     BACKGROUND 
     A wearable consumer product may be attached to a user in a variety of manners. Many traditional systems for attaching a consumer product to a user may be difficult or cumbersome. Additionally, traditional systems may attach a consumer product to a user in a manner that is not aesthetically pleasing. 
     SUMMARY 
     Embodiments of the present disclosure are directed to an attachment system for a consumer product. 
     In a first aspect, the present disclosure includes an attachment system. The attachment system includes a band having an insert portion. The attachment system includes an aperture within the insert portion. The attachment system further includes a lug having a cavity. The attachment system further includes a friction element disposed at, and extending away from, an outer surface of the lug and defining a protrusion. The attachment system further includes a pin. The attachment system further includes a retention member positioned within the cavity. The attachment system may be configured to retain the pin within the aperture upon advancement of the pin past the retention member. 
     A number of feature refinements and additional features are applicable in the first aspect and contemplated in light of the present disclosure. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features that will be discussed may be, but are not required to be, used with any other feature combination of the first aspect. 
     For example, in an embodiment, the retention member may include a tapered surface extending between a first width and a second width of the cavity. The second width of the cavity may be less than a length of the pin. In this regard, the length of the pin may be elastically deformable to the second width of the cavity. In some cases, the cavity of the attachment system may include a groove disposed adjacent the retention member and configured to receive the pin. Accordingly, the pin may return to an undeformed shape upon the receipt of the pin by the groove. 
     In another embodiment, the friction element of the attachment system may include a flange. The friction element may be connected to the lug at the flange. Additionally or alternatively, the friction element may include an anchor pin. The friction element may be connected to the lug at the anchor pin. 
     According to another embodiment, the friction element may be a first friction element and the protrusion may be a first protrusion. In this regard, the attachment system may further comprise a second friction element disposed at, and extending away from, the outer surface of the lug to define a second protrusion. The attachment system may further comprise a catch member disposed between the first friction element and the second friction element at the outer surface. The catch member may be configured to move from a first position to a second position as the lug slides relative to a consumer product. In some instances, the friction element may include a shaft extending into the cavity of the lug. Accordingly, the insert portion may be configured to receive the shaft when the pin is advanced past the retention member. 
     In this regard, a second aspect of the present disclosure includes a method for assembling an attachment system for an electronic device. The method includes inserting a sleeve into a channel of an attachment structure. The method further includes attaching the sleeve to the lug. The method includes advancing a band into the sleeve.

     In this regard, a third aspect of the present disclosure includes a method for reinforcing a strap. The method includes placing a woven strap adjacent a metal sheet. The metal sheet may include a securement mechanism. The method further includes inducing a flow of electrical current across a segment of the metal sheet such that the metal sheet produces heat to melt at least a portion of the woven strap. The method further includes causing the melted portion of the woven strap to flow toward the securement mechanism for bonding of the woven strap and the metal sheet. 
     A number of feature refinements and additional features are applicable in the third aspect and contemplated in light of the present disclosure. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features that will be discussed may be, but are not required to be, used with any other feature combination of the third aspect. 
     For example, in an embodiment, the securement mechanism may be an opening. Further, the woven strap may be a hollow woven strap configured to encircle the metal sheet. 
     In another embodiment, the causing may include compressing the woven strap and the metal sheet with a non-metal fixture. In some instances, the woven strap may include a first surface and a second surface. Accordingly, the second surface of the woven strap may not be melted by the flow of electrical current across the metal sheet. 
     In this regard, a fourth aspect of the present disclosure includes a method for assembling an over-molded attachment system. The method includes placing a band within a form. The band may include a securement mechanism. The method further includes causing material to flow into the form and toward the securement mechanism to define a housing enveloping a portion of the band for bonding of the band and the housing. The method further includes creating an aperture within a region of the band that is vertically aligned with an opening of the housing. The method further includes positioning a friction element within the aperture and the opening such that at least a portion of the friction element protrudes from an outer surface of the housing. 
     A number of feature refinements and additional features are applicable in the fourth aspect and contemplated in light of the present disclosure. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features will be discussed may be, but are not required to be, used with any other feature combination of the fourth aspect. 
     For example, in an embodiment, the securement mechanism may be a groove. Additionally or alternatively, the securement mechanism may be a pin extending from a surface of the band. 
     In another embodiment, the material may be an injection-moldable plastic. In some instances, the method further includes, before the causing, positioning a plate adjacent the band. The plate may have a greater stiffness than the band. 
     According to another embodiment, the material is a first material, the housing is a first housing, and the form is a first form. In this regard, the method may further include placing the first housing into a second form. The method may further include causing a second material to flow into the second form to define a second housing enveloping the first housing. In some instances, the second housing may include a different stiffness than the first housing. 
     In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following description.

     DETAILED DESCRIPTION 
     The description that follows includes sample systems, methods, and apparatuses that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein. 
     The present disclosure describes systems, devices, and techniques related to an attachment system for a consumer product. The attachment system may attach a consumer product to a user. In one instance, this may include attaching a wearable device (e.g., including an electronic or non-electronic device) to the wrist of a user. The attachment system may include a substantially rigid component configured to removeably engage the attachment system with a consumer product. The attachment system may also include a substantially flexible component that is non-separably interlocked with the rigid component. The term “non-separable,” or variants thereof, means that associated components, elements, or the like are permanently affixed to one another, and/or are not intentionally separable. The flexible component may include one or more features to attach the consumer product to the user. 
     The attachment system may be used as an accessory for a consumer product. In one implementation, the attachment system may be interchangeable with a variety of consumer products. This may allow the attachment system to be used with an ecosystem of consumer products that includes a common engagement structure. The common engagement structure may be configured for removable engagement with any one of a group of attachment systems described herein. Accordingly, the group of attachment systems may be interchangeable with the ecosystem of consumer products. In this manner, different ones of the group of attachment systems may be interchanged with a given consumer product based on a user&#39;s preferences. 
     In some instances, it may be useful to interchange attachment systems to aesthetically, structurally, and/or functionally enhance the consumer product. The attachment system may be removeably engaged with a consumer product. In particular, the attachment system may be removeably engageable with a consumer product while maintaining a non-separable interlock between the flexible component and the rigid component of the attachment system. The rigid component may therefore include one or more features (e.g., including a catch member, various friction elements, or the like, described in greater detail below) that facilitate the removeable engagement of the attachment system with the consumer product. Further, the rigid component may include one or more features (e.g., including a cavity having a retention member, receiving groove, or the like, described in greater detail below) that may affix or non-separably interlock the rigid component and flexible component. As such, the rigid component may form a connection between the flexible component and the consumer product. In some instances, the rigid component may have a greater material stiffness as compared to the flexible component, thereby providing a reinforced connection between the flexible component and the consumer product. 
     The rigid component and the flexible component may be non-separably interlocked in a manner that maintains the aesthetic properties (e.g., color, texture, shape, etc.) of the attachment system. For example, a portion of the flexible component may be received within a cavity of the rigid component. The portion of the flexible component received within the cavity may be non-separably interlocked with the rigid component at a location within the cavity. The non-separably interlocked connection of the flexible component and the rigid component may be concealed from the user. This may create the appearance of a seamless connection between the flexible component and the rigid component. 
     In some example embodiments, the flexible component may include a band, strap, or other feature attachable to a user. The band may be a fabric or textile band, lanyard strap, or the like formed from any appropriate material (e.g., nylon, fluroelastomeric polymer, or other suitable polymer). The insert portion may be defined by a segment of the band that is received by the rigid component. In some cases, the insert portion may be defined as two prongs extending from a side surface of the band. For example, the insert portion may be received within a cavity of the rigid component to non-separably interlock the flexible component and the rigid component. In this regard, the insert portion may include one or more features configured to non-separably interlock the rigid component and the flexible component, including, for example, one or more apertures. In one example embodiment, the apertures may be coupled with a pin that projects into the cavity of the rigid component when the rigid component receives the insert portion. This may non-separably interlock the flexible component and the rigid component. 
     In an illustrative embodiment, the rigid component may be a lug, attachment structure, housing, or other structure. The lug may be a metallic or non-metallic structure having a material stiffness greater than the band. The lug provides a connection between the band and, for example, a consumer product. In particular, the lug may define a structure configured for removable engagement with the consumer product, while maintaining a non-separable interlock with the band. 
     To facilitate the foregoing, the lug may include a retention member contained at least partially within a cavity of the lug. The retention member may include various structural features to non-separably interlock the band and the lug. In one embodiment, the retention member may include a tapered surface extending between a first width and a second width of the cavity. The first width may substantially correspond to a height of a pin disposed within an aperture of the band. The second width may substantially correspond to a height of the insert portion of the band. In this regard, the pin may be elastically deformed as the pin is advanced (while being disposed within the insert portion) past the retention member (e.g., due to the second width being less than the height of the pin). 
     A groove positioned within the cavity may receive the pin (e.g., upon the advancement of the pin past the retention member). The pin may return to an undeformed state within the groove. Accordingly, the retention member may retain the pin within the cavity due in part to the second width of the tapered surface being less than an undeformed height of the pin. This may cause the retention member to restrict movement of the band by forming a barrier between the pin (disposed within an aperture of the band) and an entrance to the cavity. Additionally or alternatively, an adhesive layer may be applied within the cavity (e.g., within the groove) to secure the pin to a surface of the cavity. 
     The lug may also include one or more features configured to removeably engage the attachment system with the consumer product. As one non-limiting example, the lug may be coupled with a spring-biased mechanism at least partially disposed at an outer surface of the lug. A portion of the spring-biased mechanism may be configured to move from a first position to a second position as the lug slides relative to the consumer product. In one embodiment, the second position of the spring-biased mechanism may define a protrusion extending from the outer surface of the lug. The protrusion may be received by an aperture, groove, or other appropriate mechanism of the consumer product to removeably engage the lug and the consumer product. The receipt of the spring-biased mechanism by the consumer product may couple the attachment system to the consumer product until, for example, the spring-biased mechanism is released or otherwise disengaged from the consumer product. 
     As another example, one or more friction elements or alignment features may be disposed on the outer surface of the lug. The friction elements may define a protrusion extending away from the outer surface of the lug. The friction elements may be configured to form a friction or interference fit with a channel or other receiving aperture of the consumer product. This may allow the friction element to align the lug with the consumer product (e.g., by maintaining a spacing between the lug and the consumer product). In some implementations, the friction elements may include one or more features (e.g., such as a shaft, flange, anchor pin, or the like) that may extend into the lug and optionally couple with one or more features of the band and/or lug. 
     The attachment systems described herein may include one or more elements that facilitate the non-separable interface between the lug and the band. As one example, a sleeve may be positioned between the lug and the band. The sleeve may be coupled to the cavity and configured to receive the insert portion of the band. In some instances, the sleeve may be welded to the lug. One or more pins may be disposed within apertures of the insert portion such that the pins extend beyond a surface of the insert portion. The pins may engage an interior surface of the sleeve upon advancement of the insert portion into the cavity. In some instances, the pin may form an interference or friction fit with the sleeve. The friction or interference fit between the pin and the interior surface of the sleeve non-separably interlocks the band and the lug. 
     In some instances, it may be desirable to couple the band with a reinforcement member to structurally reinforce the band. For example, the portions of the band surrounding the one or more apertures of the insert portion may be subject to enhanced material stresses, for example, caused by forces associated with wear and tear, etc. A reinforcement member having a greater material stiffness than the band may provide structural support to selectively identified segments of the band (e.g., such as the area surrounding the one or more apertures), thereby enhancing the longevity of the attachment system. 
     Accordingly, embodiments described herein relate to a method for reinforcing a band, strap, or other feature attachable to user (e.g., such as a band formed from the flexible component described above). To facilitate the foregoing, the band may be disposed adjacent a metal sheet. The metal sheet may define a reinforcement member. The reinforcement member may structurally reinforce the band. The metal sheet may include at least one securement mechanism (e.g., an aperture, protrusion, and/or other feature of the metal sheet) configured to receive a portion of the adjacently disposed band. A flow of electrical current may be induced across the metal sheet to produce heat to melt at least a portion of the band. The melted portion of the flexible band may flow toward (and be received by) the securement mechanism (e.g., due to a compressive force applied to the surface of the flexible band) to bond the band and the metal sheet. 
     The metal sheet may be joined to the band in a manner that maintains the aesthetic properties of the band (e.g., in a manner that renders the band substantially free of surface defects and/or other imperfections indicative of the joining process). In one implementation, a portion of the band disposed adjacent the metal sheet may be caused to melt. This may prevent a portion of the band opposite the metal sheet from melting by the induced flow of electrical current. As such, the non-melted portions of the flexible band may be substantially free of defects, notwithstanding the joining of the band to the metal sheet. 
     In certain other embodiments, it may be desirable to directly attach (e.g., via welding) the band to the lug. This may be accomplished, in one embodiment, by positioning a portion of a reinforcement member (coupled with the band according to the techniques described herein) to extend beyond the perimeter of the band. The portion of the reinforcement member that extends beyond the perimeter of the band may be received by an aperture and/or any other appropriate structure of the lug. A welded connection may be formed between the reinforcement member and the aperture. This may non-separably interlock the band to the lug. 
     In another embodiment, the lug may be an over-molded component. The lug may be constructed from an injection-moldable plastic that is molded over the band. To attach the band to the lug, the band may be placed within a form that may substantially define the shape of the lug. Material (e.g., injection-moldable plastic and/or any other suitable polymers) may flow into the form and towards the band to create a lug that envelops a portion of the band within the form. In some instances, the band may include a securement mechanism (e.g., an aperture, protrusion, and/or other feature of the band) to facilitate the bonding of the band and the material. For example, the band may include a recess such that material introduced into the form is directed toward the recess to affix the band and the material. Additionally or alternatively, the over-molded lug may be coupled with various features configured to removeably engage the attachment system with the consumer product (e.g., such as a catch member, friction elements, and/or the like). 
     Reference will now be made to the accompanying drawings, which assist in illustrating the various features of the present disclosure. The following description is presented for purposes of illustration and description. Furthermore, the description is not intended to limit the inventive aspect to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the present inventive aspect. 
       FIG. 1  depicts an example system  100  including an attachment system  104 , such as the attachment system generally discussed above and described in more detail below. The attachment system  104  includes a lug configured for removable engagement with a consumer product  108 . It will be appreciated that the lug may be an attachment structure, housing, or other structure configured to removeably engage with a consumer product. 
     The attachment system  104  may be used with a variety of consumer products. Some example consumer products may include an electronic device, a mechanical device, an electromechanical device, or the like. In one example, the consumer product may be a wearable product, including watches, glasses, rings, or the like. Other examples of the consumer products may include mobile phones, personal digital assistants, music players, timekeeping devices, health monitoring devices, tablet computers, portable storage devices, or the like. Although the above examples include electronic devices, the attachment system  104  may be used with non-electronic devices, including purely mechanical timepieces, luggage, purses, jewelry, or the like. 
     For purposes of illustration,  FIG. 1  depicts a consumer product  108  including a device housing  112 ; a display  116 ; one or more input/output members  120 ; a crown  124 ; and a channel  128 . It should be noted that the consumer product  108  may also include various other components, such as one or more ports (e.g., charging port, data transfer port, or the like), additional input/output buttons, and so on. As such, the discussion of any consumer product, such as consumer product  108 , is meant as illustrative only. 
     As further illustrated in  FIG. 1 , the attachment system  104  may include a lug  132  configured for removable engagement with the consumer product  108 . The lug  132  may be an attachment structure, housing, or the like and may include (or be coupled with) a spring-biased mechanism (not shown in  FIG. 1 ), described in greater detail below. The spring-biased mechanism may removeably engage the attachment system  104  with the consumer product  108 . As shown in  FIG. 1 , the lug  132  may be at least partially received within the channel  128  of the consumer product  108 . The spring-biased mechanism may at least partially extend from an outer surface of the lug  132  to engage a corresponding receiving structure of the channel  128  (e.g., including a corresponding receiving aperture, recess, or the like). This may allow the lug  132  to be coupled to the consumer product  108  until the spring-biased mechanism is released or otherwise disengaged from the consumer product  108 , according to the embodiments described herein. 
     The attachment system  104  may also include a band  136 . The band  136  may be non-separably interlocked with the lug  132 . The band  136  may include an insert portion (not shown in  FIG. 1 ) that is received by a cavity of the lug  132 . The insert portion of the band  136  may be coupled with one or more features (e.g., including a pin, sleeve, plate, or the like, described in greater detail below) configured to non-separably interlock the band  136  and the lug  132 . The band  136  may be a fabric or textile band, lanyard, strap, or the like formed from any appropriate material (e.g., including nylon, fluroelastomeric polymer, or other suitable polymers). More broadly, the band  136  may be any appropriate “soft good” material that exhibits sufficiently compliant and flexible characteristics. For example, the band  136  may be sufficiently elastic or resilient such that the band  136  does not permanently deform from applied force. (e.g., the band  136  may substantially return to an original or un-deformed shape after the force ceases). The band  136  may not be limited to the above exemplary materials, and may also include any other appropriate materials consistent with the various embodiments presented herein, including silicone, plastic or other flexible materials. 
     The lug  132  may be constructed from any sufficiently rigid material. In one embodiment, the lug  132  may be formed from a material having a greater material stiffness than the band  136 . The lug  132  may be a metallic component, including stainless steel, aluminum, or other metals or metal alloys having a greater material stiffness than the band  136 . Additionally or alternatively, the lug  132  may be formed substantially from a plastic component. As one example, the lug  132  may be formed from a hardened injection-moldable plastic. 
       FIGS. 2A-2D  illustrate various views and components of an attachment system  200 , according to one or more embodiments of the present disclosure. The attachment system  200  shown and described with respect to  FIGS. 2A-2D  may be substantially analogous to the attachment system  104  described above with respect to  FIG. 1 . For example, the attachment system  200  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  200  may include a substantially flexible component and a substantially rigid component. Specific shapes and orientations are described below with respect to the attachment system  200  and the various components of the attachment system  200 . However, the disclosed shapes and orientations of the attachment system  200 , and its associated components, are not limiting and are used as examples. Accordingly, similar shapes and orientations of the attachment system  200 , and its associated components, described below with respect to  FIGS. 2A-2D  may be used with the various embodiments of the attachment system described herein. 
       FIG. 2A  illustrates an exploded view of the attachment system  200 , according to one or more embodiments of the present disclosure. The attachment system  200  may include a lug  204 . As described above, the lug  204  may be an attachment structure, housing, or other appropriate structure configured to removeably engage with a consumer product. A cavity  206  may be defined within an internal volume of the lug  204 . As such, the lug  204  may be a substantially hollow structure. The lug  204  may be configured for removable engagement with the consumer product  108  while maintaining a non-separable interlock between the lug  204  and a flexible component of the attachment system  200  (e.g., such as a band, strap, or other feature that is attachable to a user, as described in greater detail below). 
     The lug  204  may have an elongated and rounded shape that is configured to be at least partially received by a receiving structure of the consumer product  108  (e.g., such as channel  128  depicted in  FIG. 1 ). The lug  204  may be coupled with one or more features to facilitate the removable engagement of the lug  204  with the consumer product  108 . For example, as depicted in  FIG. 2A , the lug  204  may be coupled with a catch member  208 , a ramp  210 , and friction elements  212 . 
     The catch member  208  and the ramp  210  may together define a spring-biased locking mechanism that is configured to removeably engage the lug  204  with the consumer product  108 . In one embodiment, the catch member  208  and the ramp  210  may be disposed at opposing external surfaces of the lug  204 . The lug  204  may include port  216  that extends between the opposing external surfaces of the lug  204 . The port  216  may be configured to receive the catch member  208  and the ramp  210  for coupling of the catch member  208  and the ramp  210  to the lug  204 . The lug  204  may include biasing springs  209  that may be positioned within the port  216  and extend between the catch member  208  and the ramp  210  in an assembled configuration. In the assembled configuration, the catch member  208  may be substantially flush against a first surface of the lug  204  and the ramp  210  may protrude from the opposing, second surface of the lug  204 . 
     The biasing springs  209  may be engaged with each of the catch member  208  and the ramp  210  such that the catch member  208  is biased away from the ramp  210 . Thus, when the ramp  210  moves in a direction toward the catch member  208  (and the catch member  208  is not prevented from expanding), the biasing springs  209  may cause the catch member  208  to move in a direction away from the ramp  210 . This may cause the catch member  208  to be biased to protrude from an external surface of the lug  204  upon the advancement of the ramp  210  towards the catch member  208 . 
     In one implementation, the insertion of the lug  204  into the channel  128  of the consumer product  108  may cause the biasing springs  209  to compress. To illustrate, the insertion of the lug  204  into the channel  128  may cause the ramp  210  to move towards the catch member  208  while the channel  128  prevents the catch member  208  from expanding. Upon further advancement into the channel  128 , the catch member  208  may be allowed to expand into a recess of the channel  128 . The expansion of the catch member  208  into the recess of the consumer product  108  may cause the lug member  204  to removeably engage the consumer product  108  (e.g., movement of the lug  204  may be restricted upon the expansion of the catch member  208  into the recess). 
     The lug member  204  may be removed from the consumer product  108  by causing the catch member  208  to move towards the ramp  210  such that the catch member  208  is no longer received by the recess of the channel  128 . For instance, in some embodiments, the recess of the channel  128  may be a through portion. This may allow a surface of the catch member  208  to receive a force that moves the catch member  208  towards the ramp  210 . Upon the movement of the catch member  208  towards the ramp  210  (e.g., such that the catch member  208  is no longer received by the recess), the movement of the lug member  204  may be substantially unrestricted. Accordingly, the lug member  204  may be slideably removed from the channel to facilitate the removable engagement of the attachment system  200  with the consumer product  108 . 
     The lug  204  may also by coupled with friction elements  212 . The friction element may be an alignment feature that is configured to maintain a spacing between, for example, the lug  204  and an associated consumer product. Friction elements  212  may be disposed on, and protrude from, one or more exterior surfaces of the lug  204 . The friction elements  212  may be configured to maintain a spacing between the lug member  204  and the channel  128  of the consumer product  108 . The friction elements  212  may form a friction or interference fit between the lug  204  and an interior surface of the channel  128 . As depicted in  FIG. 2A , each of the friction elements  212  may include substantially similar components. However, individual ones of the friction elements  212  may include any appropriate components, including different or varying components, according to the embodiments described herein. 
     The friction elements  212  may be coupled to an outer surface of the lug  204  at an opening of the lug  204 . In one embodiment, the lug  204  may include openings  218 . The friction elements  212  may be positioned within the openings  218  to couple the friction elements  212  to the lug  204 . The friction elements  212  may be coupled to the openings  218  in a variety of manners. For example, in the embodiment depicted in  FIG. 2A , the attachment system  200  may include flanges  220 . 
     In one embodiment, the flanges  220  may be positioned on the friction elements  212  such that the flanges  220  may be interposed between the friction elements  212  and the lug  204 . The flanges  220  may be configured to couple the friction elements  212  to the lug  204 . For example, in one embodiment, the flanges  220  may extend beyond a perimeter of the friction elements  212 . This may allow the friction elements  212  to be disposed within the openings  218  such that the flanges  220  extend into the cavity  206  of the lug  204 . The flanges  220  (when positioned in the cavity) may restrict movement of the friction elements  212 , thereby facilitating the coupling of the friction elements  212  to the lug  204 . Additionally or alternatively, an adhesive layer may be applied adjacent to the flanges  220  to couple the friction elements  212  to the lug  204 . 
     The attachment system  200  may also include a band  224 . The band may be a strap or other feature attachable to a user. The band  224  may be non-separably interlocked with the lug  204 . A portion of the band  224  may be received within the cavity  206  of the lug  204  to non-separably interlock the band  224  and the lug  204 . The band  224  may include an insert portion  228 . The insert portion  228  may be defined by a segment of the band  224  that is configured to be received by the lug  204 . In some case, the insert portion  228  may be defined by two prongs extending from a side surface of the band  224 . The insert portion  228  may include various features configured to non-separably interlock the band  224  with the lug  204 . For example, the insert portion  228  may include apertures  232 . The apertures  232  may be configured to receive a pin and/or other appropriate mechanism that may engage with the lug  204 . 
     The attachment system  200  may include pins  236 . The pins  236  may be a substantially cylindrical shape. The pins  236  may be disposed within the apertures  232  and extend beyond a surface of the insert portion  228 . For example, the pins  236  may have a length that is greater than a height of the insert portion  228 . Accordingly, the pins  236  may protrude from one, or both, sides of the insert portion  228  when disposed within the apertures  232 . 
     In one embodiment, the pins  236  may include studs  240 . The studs  240  may define protrusions extending from opposing external surfaces of the pins  236 . In one instance, the studs  240  may have a diameter that is less than a diameter of the pins  236 . The studs  240  may be configured for engagement with a surface of the cavity  206  to non-separably interlock the lug  204  and the band  224 . 
     The cavity  206  may include, or be coupled with, retention members  244 . The retention members  244  may include a tapered surface that extends between a first cavity width and a second cavity width. Both a top and bottom surface of the cavity  206  may be tapered in this manner to define the retention members  244 . In one instance, the tapered surface may be configured such that the first width may correspond to a height of the pins  236  and the second width may correspond to a height of the insert portion  228 . 
     The cavity may include grooves  248 . The grooves  248  may be positioned adjacent to the retention members  244  and opposite entrance to the cavity  206  (e.g., such as cavity entrance  207 ). Grooves  248  may be configured to receive the pins  236 . By way of example, the grooves  248  may be dimensioned corresponding to the dimension of the studs  240 . As such, the studs  240  may be received by the grooves  248  upon the advancement of the pins  236  past the retention members  244 . This may non-separably interlock the lug  204  and the band  224 . 
       FIG. 2B  illustrates a top view of the assembled attachment system  200  of  FIG. 2A , according to one or more embodiments of the present disclosure. The insert portion  228  is placed within the cavity  206  such that the band  224  is non-separably interlocked with the lug  204 . The insert portion  228  may be substantially disposed within the cavity  206  such that the various components described herein to facilitate the non-separable interlock of the band  224  and the lug  204  (e.g., the retention members  244 , the pins  236 , etc.) may be concealed from view in the assembled state. Further, the one or more features used to couple the friction elements  212  to the lug  204  (e.g., such as flanges  220 ) may similarly be concealed from view. In this regard, the attachment system  200  may non-separably interlock the band  224  and the lug  204  in a manner that maintains the aesthetic properties of the attachment system  200 . 
       FIGS. 2C-2D  illustrate various cross-sectional views of the attachment system  200 . In particular,  FIG. 2C  is a cross-sectional view of the attachment system  200 , taken along line A-A of  FIG. 2B .  FIG. 2D  is a cross-sectional view of the attachment system  200 , taken along line B-B of  FIG. 2B . As illustrated, the band  224  may be non-separably interlocked with the lug  204 . To facilitate the foregoing, the insert portion  228  may be disposed within the cavity  206  such that the apertures  232  are positioned past retention members  244  (e.g., the retention members  244  may be interposed between the apertures  232  and the cavity entrance  207 ). In some instances, the apertures  232  may be vertically aligned with the grooves  248  and/or the friction elements  212 . 
     In the assembled configuration, the pins  236  may be disposed within the apertures  232  and extend into the grooves  248 . A portion of the pins  236  (e.g., such as studs  240 ) may extend beyond an external surface of the insert portion  228  such that the pins  236  may be received by the grooves  248 . The grooves  248  may be defined by a shape corresponding to the shape of the studs  240  (e.g., the grooves  248  may have a diameter substantially equal to or greater than the studs  240 ). 
     In some instances, the cavity  206  may include grooves  248 . The grooves  248  may be disposed adjacent opposing external surfaces of the pins  236  in the assembled state. In this manner, the studs  240  extending from the opposing external surfaces of the pins  236  may be received by the grooves  248 . This may allow the grooves  248  to restrict axial movement of the pins  236 . 
     The disposition of the pins  236  within the grooves  248 , in conjunction with the retention members  244 , may non-separably interlock the band  224  and the lug  204 . For example, the retention members  244  may be positioned within the cavity  206  to retain the pins  236  upon the advancement of the pins  236  past the retention members  244 . The retaining of the pins  236  within the cavity  206  may non-separably interlock the band  224  and the lug  204 . To illustrate, in the assembled configuration, the pins  236  may be disposed within the apertures  232  of the insert portion  228  and advanced into the cavity  206  past the retention members  244 . Once advanced past the retention members  244 , at least a portion of the pins  236  may extend into the grooves  248 . Upon receipt by the grooves  248 , movement of the band  224  relative to the lug  204  may be substantially restricted. By way of particular example, the retention members  244  may form a barrier between the pins  236  and the cavity entrance  207 . The band  224  may therefore be prevented from exiting the cavity  206  for at least because the pins  236  (which are restricted from moving) may be disposed within apertures  232 . 
     To facilitate the foregoing, the retention members  244  may be at least partially defined by a tapered surface of the cavity  206  that extends between a first cavity width  252  and a second cavity width  256 . The first cavity width  252  may have a cross dimension that may be greater than a cross dimension of the second cavity width  256 . As such, the cavity  206  may have a cross-dimensional area that may gradually decrease between the first cavity width  252  and the second cavity width  256 . In one implementation, the first cavity width  252  may substantially correspond to a pin length  260  and the second cavity width  256  may substantially correspond to an insert portion length  264 . The pin length  260  may be a longitudinal length of the pins  236  and the studs  240 . 
     The insert portion  228  may be advanced into the cavity  206  in a state in which the pins  236  are disposed within the apertures  232 . Upon advancement of the insert portion  228  into the cavity  206 , the first cavity width  252  may accommodate the pin length  260  such that the pins  236  may initially pass into the cavity  206  in an undeformed state. Upon further advancement of the insert portion  228  into the cavity  206 , the pins  236  may be compressed. In particular, the pins  236  may be elastically deformed from the pin length  260  to the second cavity width  256  as the pins  236  move past the retention members  244 . 
     The pins  236  may be advanced past the retention members  244  to non-removeably capture the pins  236  within the cavity  206 . Upon advancement of the pins  236  past the retention members  244 , the pins  236  may be received by the grooves  248 . The grooves  248  may be dimensioned such that the pins  236  may return to an undeformed shape upon the receipt of the pins  236  by the grooves  248 . As such, the retention members  244  may define a barrier between the pins  236  and the cavity entrance  207 . Accordingly, the retention members  244  may non-removeably capture the pins  236  within the cavity  206 . The non-removable capture of the pins  236  may non-separably interlock the band  224  and the lug  204  (e.g., the pins  236  disposed within the apertures  232  may prevent the band  224  from exiting the cavity  206 ). 
       FIGS. 3A-3E  illustrate various views and components of an attachment system  300 , according to one or more embodiments of the present disclosure. The attachment system  300  shown and described with respect to  FIGS. 3A-3E  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  300  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  300  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  300  may include: lug  304 ; cavity  306 ; cavity entrance  307 ; catch member  308 ; ramp  310 ; biasing springs  309 ; friction elements  312 ; port  316 ; openings  318 ; band  324 ; insert portion  328 ; apertures  332 ; pins  336 ; studs  340 ; retention members  344 ; and grooves  348 . Further, analogous to the embodiments of  FIGS. 2A-2D , the cavity  306  may include a first cavity width  352  and a second cavity width  356 ; the pins  336  may include a pin length  360 ; and the insert portion  328  may include an insert portion length  364 . 
       FIG. 3A  illustrates an exploded view of the attachment system  300 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  300  may include one or more sets of anchor pins configured to couple the friction elements  312  to the lug  304 . As illustrated in the embodiment depicted in  FIG. 3A , the attachment system  300  may include anchor pins  320 . 
     In one embodiment, the anchor pins  320  may be positioned adjacent the friction elements  312  such that the anchor pins  320  may be interposed between the friction elements  312  and the lug  304 . The anchor pins  320  may be configured to couple the friction elements  312  to the lug  304 . The anchor pins  320  may be positioned on the friction elements  312  such that the anchor pins  320  protrude from an external surface of the friction elements  312 . This may allow the friction elements  312  to be disposed with the opening  318  such that the anchor pins  320  extend into the cavity  306  of the lug  304  in an assembled state. In one embodiment, the lug  304  may include holes  321  that may be configured to receive the anchor pins  320  to facilitate coupling the friction elements  312  to the lug  304 . Additionally or alternatively, an adhesive layer may be applied adjacent to one or more of the anchor pins  320  to attach the corresponding friction elements  312  to the lug  304 . 
       FIG. 3B  illustrates a top view of the assembled attachment system  300  of  FIG. 3A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  328  is placed within the cavity  306  such that the band  324  is non-separably interlocked with the lug  304 . The insert portion  328  may be substantially disposed within the cavity  306  such that the various components described herein to facilitate the non-separable interlock of the band  324  and the lug  304  (e.g., the retention members  344 , the pins  336 , etc.) may be concealed from view in the assembled state. Further, the one or more features used to couple the friction elements  312  to the lug  304  (e.g., such as anchor pins  320 ) may similarly be concealed from view. In this regard, the attachment system  300  may non-separably interlock the band  324  and the lug  304  in a manner that maintains the aesthetic properties of the attachment system  300 . 
       FIGS. 3C-3E  illustrate various cross-sectional views of the attachment system  300 . In particular,  FIG. 3C  is a cross-sectional view of the attachment system  300 , taken along line C-C of  FIG. 3B ;  FIG. 3D  is a cross-sectional view of the attachment system  300 , taken along line D-D of  FIG. 3B ; and  FIG. 3E  is a cross-sectional view of the attachment system  300 , taken along line E-E of  FIG. 3B . As illustrated, the band  324  may be non-separably interlocked with the lug  304  in a manner substantially analogous to that described with respect to the attachment system  200  depicted in  FIGS. 2A-2D . For example, insert portion  328  may be disposed with the cavity  306  such that the retention members  344  may retain the pins  336 . 
     As depicted in  FIGS. 3C-3E , friction elements  312  may be connected to anchor pins  320 . In an assembled state, the anchor pins  320  may be positioned within holes  321 . The holes  321  may restrict movement at the anchors pins  320 . As such, the friction elements  312  may be coupled to the lug  304  using the anchor pins  320 . In some cases, an adhesive and/or other appropriate bonding technique may be used for affixing the anchor pins  320  to the lug  304  at the holes  321 . As shown in  FIG. 3E , the anchor pins  320  may include a first and a second of anchor pins  320  disposed at opposing ends of the friction elements  312 . 
       FIGS. 4A-4D  illustrate various views and components of an attachment system  400 , according to one or more embodiments of the present disclosure. The attachment system  400  shown and described with respect to  FIGS. 4A-4D  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  400  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  400  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  400  may include: lug  404  cavity  406 ; cavity entrance  407 ; catch member  408 ; ramp  410 ; biasing springs  409 ; friction elements  412 ; port  416 ; openings  418 ; band  424 ; insert portion  428 ; apertures  432 ; pins  436 ; studs  440 ; retention members  444 ; and grooves  448 . Further, analogous to the embodiments of  FIGS. 2A-2D , the cavity  406  may include a first cavity width  452  and a second cavity width  456 ; the pins  436  may include a pin length  460 ; and the insert portion  428  may include an insert portion length  464 . 
       FIG. 4A  illustrates an exploded view of the attachment system  400 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  400  may include one or more shafts configured to couple the friction elements  412  to the lug  404 . The one or more shafts may also be configured to non-separably interlock the band  424  and the lug  404  (e.g., by providing a barrier between a segment of the insert portion  428  and the cavity entrance  407 ). As illustrated, in the embodiment depicted in  FIG. 4A , the attachment system  400  may include shafts  420 . 
     In one embodiment, the shafts  420  may be positioned on the friction elements  412  such that the shafts  420  may be interposed between the friction elements  412  and the lug  404 . The shafts  420  may be configured to couple the friction elements  412  to the lug  404 . To illustrate, the shafts  420  may protrude from an external surface of the friction elements  412  In an assembled state, the shafts  420  may extend into the cavity  406  and through the insert portion  428  to couple the friction elements  412  with the lug  404 . 
     In one embodiment, the insert portion may include holes  421 . In the assembled state, the shafts  420  may extend through the holes  421 . As such, the shafts  420  may be used to non-separably interlock the band  424  and the lug  404 , for example, because the shafts  420  form a physical barrier between a portion of the band  424  and the cavity entrance  407 . In some embodiments, the shafts  420  may extend through the holes  421  for engagement with another of the friction elements  412 . 
     To facilitate the foregoing, the friction elements  412  may include receiving recesses  422 . The receiving recesses  422  may be configured to receive at least a portion of the shafts  420  that extends through the holes  421 . This may allow a pair of the friction elements  412  disposed at opposing external surfaces of the lug  404  to operate together to couple the pair of friction elements  412  to the lug  404 . For example, each of the pair of friction elements  412  may include one of the shafts  420  and one of the receiving recesses  422 . Each one of the shafts  420  may extend through a corresponding one of the holes  421  and engage a receiving recess  422  of the other one of the friction elements  412  (e.g., the shafts  420  of one of the friction elements  412  may be received by one of the receiving recesses  422  of another of the friction elements  412  that is disposed on the opposite external surface of the lug  404 ). In some instances, the receiving recesses  422  may form a friction or interference fit with the shafts  420 . Additionally or alternatively, an adhesive layer may be applied adjacent to the receiving recesses  422  to couple the shafts  420  to the receiving recesses  422 . 
       FIG. 4B  illustrates a top view of the assembled attachment system  400  of  FIG. 4A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  428  is placed within the cavity  406  such that the band  424  is non-separably interlocked with the lug  404 . The insert portion  428  may be substantially disposed within the cavity  406  such that the various components described herein to facilitate the non-separable interlock of the band  424  and the lug  404  (e.g., the retention members  444 , the pins  436 , etc.) may be concealed from view in the assembled state. As shown in  FIG. 4A , insert portion  428  may include two prongs. Further, the one or more features used to couple the friction elements  412  to the lug  404  (e.g., such as shafts  420 ) may similarly be concealed from view. In this regard, the attachment system  400  may non-separably interlock the band  424  and the lug  404  in a manner that maintains the aesthetic properties of the attachment system  400 . 
       FIGS. 4C-4D  illustrate various cross-sectional views of the attachment system  400 . In particular,  FIG. 4C  is a cross-sectional view of the attachment system  400 , taken along line F-F of  FIG. 4B .  FIG. 4D  is a cross-sectional view of the attachment system  400 , taken along line G-G of  FIG. 4B . In this regard, as illustrated, the band  424  may be non-separably interlocked with the lug  404  in a manner substantially analogous to that of attachment system  200  depicted in  FIGS. 2A-2D . For example, insert portion  428  may be disposed within the cavity  406  such that the retention members  444  may retain the pins  436 . 
     The shafts  420  may define a barrier between a segment of the insert portion  428  and the cavity entrance  407  to non-separably interlock the lug  404  and the band  424 . For example, shafts  420  may extend through holes  421  of the insert portion  428  and be received by receiving recess  422 . This may cause the band  424  to be prevented from exiting the cavity  406 . Further, in the assembled configuration, pins  436  may be disposed adjacent the holes  421 . Accordingly, both the pins  436  and the shafts  420  may provide a structural barrier operative to non-separably interlock the band  424  and the lug  404 . 
       FIGS. 5A-5C  illustrate various views and components of an attachment system  500  according to one or more embodiments of the present disclosure. The attachment system  500  shown and described with respect to  FIGS. 5A-5C  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  500  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  500  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  500  may include: lug  504 ; cavity  506 ; cavity entrance  507 ; catch member  508 ; ramp  510 ; biasing springs  509 ; friction elements  512 ; port  516 ; openings  518 ; band  524 ; insert portion  528 ; apertures  532 ; pins  536 ; studs  540 ; retention members  544 ; and grooves  548 . Further, analogous to the embodiments of  FIGS. 2A-2D , the cavity  506  may include a first cavity width  552  and a second cavity width  556 ; the pins  536  may include a pin length  560 ; and the insert portion  528  may include an insert portion length  564 . 
       FIG. 5A  illustrates an exploded view of the attachment system  500 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  500  may include friction elements  512  that extend through the openings  518 . For example, in an assembled configuration, the friction elements  512  may be dimensioned to extend between, or protrude from, opposing external surfaces of the lug  504  such that the friction elements  512  may extend beyond the opposing external surfaces of the lug  504 . 
       FIG. 5B  illustrates a top view of the assembled attachment system  500  of  FIG. 5A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  528  may be placed within the cavity  506  such that the band  524  may be non-separably interlocked with the lug  504 . The insert portion  528  may be substantially disposed within the cavity  506  such that the various components described herein to facilitate the non-separable interlock of the band  524  and the lug  504  (e.g., the retention members  544 , the pins  536 , etc.) may be concealed from view in the assembled state. In this regard, the attachment system  500  may non-separably interlock the band  524  and the lug  504  in a manner that maintains the aesthetic properties of the attachment system  500 . 
       FIG. 5C  is a cross-sectional view of the attachment system  500 , taken along line H-H of  FIG. 5B  In this regard, as illustrated, the band  524  may be non-separably interlocked with the lug  504  in a manner substantially analogous to that of attachment system  200  depicted in  FIGS. 2A-2D . For example, insert portion  528  may be disposed within the cavity  506  such that the retention members  544  may retain the pins  536 . 
     As depicted in  FIG. 5C , the friction elements  512  may be disposed within openings  518  such that the friction elements  512  extend beyond opposing external surfaces of the lug  504 . In this regard, in the assembled state, the pins  536  may be offset from the friction elements  512 . The offset of the pins  536  from the friction elements  512  may allow the friction elements  512  to extend through the opposing external surfaces of the lug  504 . 
       FIGS. 6A-6D  illustrate various views and components of an attachment system  600  according to one or more embodiments of the present disclosure. The attachment system  600  shown and described with respect to  FIG. 6A - FIG. 6D  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  600  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  600  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  600  may include: lug  604 ; cavity  606 ; cavity entrance  607 ; catch member  608 ; ramp  610 ; biasing springs  609 ; friction elements  612 ; port  616 ; openings  618 ; band  624 ; insert portion  628 ; apertures  632 ; retention members  644 ; and grooves  648 . 
       FIG. 6A  illustrates an exploded view of the attachment system  600 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  600  may include one or more elements that are configured to non-separably interlock the band  624  and the lug  604  via an ultrasonic welded connection. For example, in the embodiment depicted in  FIG. 6A , the attachment system  600  may include ultrasonic pins  636 , so named as they may be ultrasonically welded to the band. It should be appreciated that the ultrasonic pins  636  may be bonded to the band through other attachment techniques and/or structures, in various embodiments. 
     In one embodiment, the ultrasonic pins  636  may be bonded to the band  624  through ultrasonic welding (e.g., application of high-frequency ultrasonic vibrations). For example and as described in greater detail below with reference to  FIG. 20 , the ultrasonic pins  636  may be joined to the band  624  (for example, at a surface and/or sidewall of the apertures  632 ) upon the application of a high-frequency ultrasonic vibration to the ultrasonic pins  636 . To illustrate, the ultrasonic vibration of the ultrasonic pins  636  may cause a portion of the band  624  disposed adjacent to the ultrasonic pins  636  to melt due to absorption of vibrational energy. The melted portion of the band  624  may bond with the ultrasonic pins  636 , or vice versa, such that the band  624  is non-separably interlocked with the pins  636 . 
     To facilitate the foregoing, at least a portion of the ultrasonic pins  636  may be a knurled surface. The knurled surface of the ultrasonic pins  636  may increase the surface area of the ultrasonic pins  636  disposed adjacent to the band  624 . In turn, the increased surface area disposed adjacent the band  624  may increase the relative strength of the bond between the band  624  and the ultrasonic pins  636 . For example, the increased surface area of the band  624  may increase the locations at which the band  624  and the ultrasonic pins  636  may be bonded together, thereby increasing the resulting strength of the bond between the band  624  and the ultrasonic pins  636 . Additionally or alternatively, the ultrasonic pins  636  may include other features or surface geometries (e.g., including various protrusions and/or recesses) to facilitate the bonding of the band  624  to the ultrasonic pins  636 . Further, analogous to the embodiments of  FIGS. 2A-2D , the cavity  606  may include a first cavity width  652  and a second cavity width  656 ; the ultrasonic pins  636  may include a pin length  660 ; and the insert portion  628  may include an insert portion length  664 . 
       FIG. 6B  illustrates a top view of the assembled attachment system  600  of  FIG. 6A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  628  may be placed within the cavity  606  such that the band  624  may be non-separably interlocked with the lug  604 . The insert portion  628  may be substantially disposed within the cavity  606  such that the various components described herein to facilitate the non-separable interlock of the band  624  and the lug  604  (e.g., including the ultrasonic pins  636 , etc.) may be concealed from view in the assembled state. In this regard, the attachment system  600  may non-separably interlock the band  624  and the lug  604  in a manner that maintains the aesthetic properties of the attachment system  600 . 
       FIGS. 6C-6D  illustrate various cross-sectional views of the attachment system  600 . In particular,  FIG. 6C  is a cross-sectional view of the attachment system  600 , taken along line I-I of  FIG. 6B .  FIG. 6D  is a cross-sectional view of the attachment system  600 , taken along line J-J of  FIG. 6B . In this regard, as illustrated, the band  624  may be non-separably interlocked with the lug  604  according to the embodiments described herein. In the illustrated assembled configuration, the insert portion  628  may be disposed within the cavity  606  such that the apertures  632  may be vertically aligned with grooves  648 . As shown in  FIG. 6A , insert portion  28  may include two prongs. The ultrasonic pins  636  may be disposed within apertures  632 . In particular, the ultrasonic pins  636  may be disposed within the apertures  632  and bonded to the band  624  at a position within the apertures  632  (e.g., by applying a high-frequency ultrasonic vibration to the ultrasonic pins  636 ). 
     The ultrasonic pins  636  may facilitate the non-separable interlock of the band  624  and the lug  604 . For example, the ultrasonic pins  636  may provide a structure extending from a surface of the insert portion  628  that engages one or more features of the lug  604  (e.g., such as groove  648 ) to restrict the movement of the band  624  relative to the lug  604 . By way of particular example, in the assembled configuration, the insert portion  628  may be positioned within the cavity  606  such that opposing external surfaces of the insert portion  628  are substantially adjacent and/or flush with surfaces of the cavity  606  (e.g., the insert portion length  664  may substantially equal the second cavity width  656 ). The ultrasonic pins  636  may have an ultrasonic pin length  660  that is greater than the insert portion length  664  and/or the second cavity width  656 . In this regard, the ultrasonic pins  636  disposed within the apertures  632  may at least partially extend from either or both of the external opposing surfaces of the insert portion  628  and into the cavity  606 . 
     The grooves  648  may be configured to receive the ultrasonic pins  636 . For example, the ultrasonic pins  636  may be disposed within the apertures  632  and extend into the grooves  648 . In this manner, the grooves  648  may restrict the movement of the band  624  relative to the lug  604  by providing a barrier between the ultrasonic pins  636  (e.g., the portion of the ultrasonic pins  636  extending from one or more surfaces of the insert portion  628 ) and the cavity entrance  607 . 
     In one embodiment, the grooves  648  may be a through portion. Accordingly, the ultrasonic pins  636  may be advanced through the grooves  648  and into the cavity  606  for disposition into the apertures  632 . In this regard, the insert portion  628  may be disposed within the cavity  606  during the application of the high-frequency ultrasonic vibration to the ultrasonic pins  636  such that the ultrasonic pins  636  may be bonded to the band  624  in a state in which the band  624  is disposed within the cavity  606 . 
       FIGS. 7A-7D  illustrate various views and components of an attachment system  700 , according to one or more embodiments of the present disclosure. The attachment system  700  shown and described with respect to  FIGS. 7A-7D  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  700  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  700  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  700  may include: lug  704 ; cavity  706 ; cavity entrance  707 ; catch member  708 ; ramp  710 ; biasing springs  709 ; friction elements  712 ; port  716 ; opening  718 ; band  724 ; insert portion  728 ; apertures  732 ; pins  736 ; retention members  744 ; and grooves  748 . Further analogous to the embodiments of  FIGS. 2A-2D , the cavity  706  may include a first cavity width  752  and a second cavity width  756 . 
       FIG. 7A  illustrates an exploded view of the attachment system  700 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  700  may include one or more elements that are configured to couple the pins  736  with the band  724 . For example, in the embodiment depicted in  FIG. 7A , the attachment system  700  may include tubes  737 . The tubes  737  may have retention features  738  configured to engage a surface feature of the pins  736 . The tubes  737  may be configured to receive the pins  736  for coupling of the pins  736  and the band  724 . The pins  736  may include engagement members  739  (e.g., as depicted in  FIGS. 7C-7D ). The engagement members  739  may be configured to couple the pins  736  and the tubes  737 . For example, the engagement members  739  may couple with the retention features  738  upon the advancement of the pins  736  into the tubes  737 . 
       FIG. 7B  illustrates a top view of the assembled attachment system  700  of  FIG. 7A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  728  may be placed within the cavity  706  such that the band  724  may be non-separably interlocked with the lug  704 . As shown in  FIG. 7A , insert portion  728  may include two prongs. The insert portion  728  may be substantially disposed within the cavity  706  such that the various components described herein to facilitate the non-separable interlock of the band  724  and the lug  704  (e.g., including the pins  736 , the tubes  737 , etc.) may be concealed from view in the assembled state. In this regard, the attachment system  700  may non-separably interlock the band  724  and the lug  704  in a manner that maintains the aesthetic properties of the attachment system  700 . 
       FIGS. 7C-7D  illustrate various cross-sectional views of the attachment system  700 . In particular,  FIG. 7C  is a cross-sectional view of the attachment system  700 , taken along line K-K of  FIG. 7B .  FIG. 7D  is a cross-sectional view of the attachment system  700 , taken along line L-L of  FIG. 7B . In this regard, as illustrated, the band  724  may be non-separably interlocked with the lug  704  according to the embodiments described herein. In the illustrated assembled configuration, the insert portion  728  may be disposed within the cavity  706  such that the apertures  732  may be vertically aligned with the grooves  748  (e.g., the apertures  732  and the grooves  748  may be positioned along a common axis). The pins  736  may be disposed within apertures  732 . This may allow the pins  736  to be coupled to the band  724  at a position within the apertures  732  via the tubes  737 . 
     The pins  736  may facilitate the non-separable interlock of the band  724  and the lug  704 . For example, the pins  736  may provide a structure extending from a surface of the insert portion  728  that engages one or more features of the lug  704  (e.g., such as groove  748 ) to restrict the movement of the band  724  relative to the lug  704 . By way of particular example, in the assembled configuration, the insert portion  728  may be positioned within the cavity  706  such that opposing external surfaces of the insert portion  728  are substantially adjacent and/or flush with surfaces of the cavity  706  (e.g., the insert portion length  764  may substantially equal the second cavity width  756 ). The pins  736  may have a pin length  760  that is greater than the insert portion length  764  and/or the second cavity width  756 . In this regard, the pins  736  disposed within the apertures  732  may at least partially extend from either, or both, of external opposing surfaces of the insert portion  728  and into the cavity  706 . 
     The cavity  706  may include grooves  748 . The grooves  748  may be configured to receive the pins  736 , which partially extend from the opposing external surfaces of the insert portion  728 . For example, the pins  736  may be disposed within the apertures  732  and extend into the grooves  748 . In this manner, the grooves  748  may restrict the movement of the band  724  relative to the lug  704  by providing a barrier between the pins  736  (e.g., the portion of the pins  736  extending from one or more surfaces of the insert portion  728 ) and the cavity entrance  707 . 
     In one embodiment, the grooves  748  may be a through portion. Accordingly, the pins  736  may be advanced through the grooves  748  and into the cavity  706  for positioning within the apertures  732 . To illustrate, the pins  736  may be advanced into the cavity  706  in a state in which the insert portion  728  is disposed within the cavity  706 . The insert portion  728  disposed within the cavity  706  may include the tubes  737 . For example, the tubes  737  may be affixed to the insert portion  728  at the aperture  732 . In this regard, the pins  736  may be coupled with the band  724  by advancing the pins  736  into the grooves  748  (e.g., via the application of a compressive force acting on the pins  736 ) to couple the pins  736  with the tubes  737 . 
       FIGS. 8A-8C  illustrate various views and components of an attachment system  800 , according to one or more embodiments of the present disclosure. The attachment system  800  shown and described with respect to  FIGS. 8A-8C  may be substantially analogous to the attachment system  200  described above with respect to  FIGS. 2A-2D . For example, the attachment system  800  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  800  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  800  may include: lug  804 ; cavity  806 ; cavity entrance  807 ; catch member  808 ; ramp  810 ; biasing springs  809 ; friction elements  812 ; port  816 ; openings  818 ; band  824 ; insert portion  828 ; apertures  832 ; pins  836 ; and studs  840 . 
       FIG. 8A  illustrates an exploded view of the attachment system  800 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  800  may include one or more connecting members configured to non-separably interlock the band  824  to the lug  804 . For example, in the embodiment depicted in  FIG. 8A , the attachment system  800  may include sleeve  870 . 
     In one embodiment, the sleeve  870  may be interposed between the band  824  and the lug  804 . The sleeve  870  may provide a structure for connecting the band  824  and the lug  804 . As one non-limiting example, the sleeve  870  may be an elongated structure that is substantially hollow. The sleeve  870  may include a sleeve cavity  872  that is defined by an internal volume of the sleeve  870 . The sleeve  870  may be dimensioned such that the sleeve  870  receives the insert portion  828  within the sleeve cavity  872 . In some embodiments, the sleeve cavity  872  may include a sleeve inner surface  874  that may include one or more features to engage the insert portion  828  (e.g., such that the pins  836  may engage the sleeve  870  to non-separably interlock the band  824  and the sleeve  870 ). 
     Further, sleeve  870  may include tabs  876 . The tabs  876  may be configured for attachment with the lug  804 . For example, the tabs  876  may extend from the sleeve  870  for positioning within the cavity  806 . In some embodiments, the sleeve  870  may be attached to the lug  804  via a welded connection. In other instances, adhesives may be applied at the tabs  876  to attach the sleeve  870  to the lug  804 . 
       FIG. 8B  illustrates a top view of the assembled attachment system  800  of  FIG. 8A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  828  may be received by the sleeve  870  in order to non-separably interlock the band  824  with the lug  804 . The insert portion  828  may be dimensioned such that an external surface of the band  824  and an external surface of the sleeve  870  may be substantially flush in a state in which the insert portion  828  is received by the sleeve  870 . This may allow the attachment system  800  to non-separably interlock the band  824  and the lug  804  in a manner that maintains the aesthetic properties of the attachment system  800 . 
       FIG. 8C  is a cross-sectional view of the attachment system  800 , taken along line M-M of  FIG. 8B . In this regard, as illustrated, the band  824  may be non-separably interlocked with the lug  804  according to the embodiments described herein. In the assembled configuration, the insert portion  828  may be disposed within the sleeve cavity  872 . The insert portion  828  may include pins  836  (which may be disposed in the apertures  832 ) of the insert portion  828 . The pins  836  may include studs  840  that may extend from an external surface of the insert portion  828  for engagement with sleeve inner surface  874 . 
     As depicted in  FIG. 8C , the studs  840  may contactably engage the sleeve inner surface  874  to form an interference or friction fit with the sleeve inner surface  874 . The interference or friction fit of the sleeve inner surface  874  and the studs  840  may restrict the movement of the band  824  relative to the sleeve  870  such that the band  824  may be non-separably interlocked with the sleeve  870 . Additionally or alternatively, the band  824  may be non-separably interlocked with the lug  804  via an adhesive layer applied between the insert portion  828  and the sleeve  870 . In some instances, a welded connection may be formed between the insert portion  828  and the sleeve  870  to non-separably interlock the band  824  and the lug  804 . 
       FIGS. 9A-9C  illustrate various views and components of an attachment system  900 , according to one or more embodiments of the present disclosure. The attachment system  900  shown and described with respect to  FIGS. 9A-9C  may be substantially analogous to the attachment system  800  described above with respect to  FIG. 8A - FIG. 8C . For example, the attachment system  900  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  900  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 8A-8C , the attachment system  900  may include: lug  904 ; cavity  906 ; cavity entrance  907 ; catch member  908 ; ramp  910 ; biasing springs  909 ; friction elements  912 ; port  916 ; openings  918 ; band  924 ; insert portion  928 ; apertures  932 ; studs  940 ; sleeve  970 ; sleeve cavity  972 ; sleeve inner surface  974 ; and tabs  976 . 
       FIG. 9A  illustrates an exploded view of the attachment system  900 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  800 , the attachment system  900  may include one or more engagement members configured to couple the band  924  to the sleeve  970 . For example, in the embodiment depicted in  FIG. 9A , the attachment system  900  may include plate  936 . The plate  936  may include a pattern of fingers  937  configured for engagement with the apertures  932  of the insert portion  928  (e.g., at least a portion of the pattern of fingers  937  may be received by apertures  932 ). The plate  936  may be coupled to the sleeve  970  to facilitate the non-separable interlock of the band  924  and the lug  904 . 
       FIG. 9B  illustrates a top view of the assembled attachment system  900  of  FIG. 9A  according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  928  may be received by the sleeve  970  in order to non-separably interlock the band  924  with the lug  904 . The insert portion  928  may be dimensioned such that an external surface of the band  924  and an external surface of the sleeve  970  may be substantially flush in a state in which the insert portion  928  is received by the sleeve  970 . In this regard, the attachment system  900  may non-separably interlock the band  924  and the lug  904  in a manner that maintains the aesthetic properties of the attachment system  900 . 
       FIG. 9C  illustrates a cross-sectional view of the attachment system  900 , taken along line N-N of  FIG. 9B . In this regard, as illustrated, the band  924  may be non-separably interlocked with the lug  904 , according to the embodiments described herein. In the illustrated assembled configuration, the insert portion  928  may be disposed within the sleeve cavity  972 . As such, the pattern of fingers  937  of the plate  936  may be disposed within the apertures  932 . For example, the pattern of fingers  937  may extend from the plate  936  such that the pattern of fingers  937  may be received by the apertures  932 . In this regard, the plate  936  may be disposed on an external surface of the insert portion  928  (e.g., such that the pattern of fingers  937  may be received by the apertures  932 ) and interposed between the insert portion  928  and the sleeve inner surface  974 . Accordingly, the plate  936  may contactably engage the sleeve inner surface  974  to form an interference or friction fit with the sleeve inner surface  974 . 
     The interference or friction fit of the sleeve inner surface  974  and the plate  936  may restrict the movement of the band  924  relative to the sleeve  970  such that the band  924  may be non-separably interlocked with the sleeve  970 . Additionally or alternatively, a welded connection may be formed between the plate  936  and the sleeve inner surface  974  to non-separably interlock the band  924  and the lug  904 . In some instances, an adhesive layer may be applied between the insert portion  928  and the sleeve  970  to non-separably interlock the band  924  to the lug  904 . 
       FIGS. 10A-10C  illustrate various views and components of an attachment system  1000 , according to one or more embodiments of the present disclosure. The attachment system  1000  shown and described with respect to  FIGS. 10A-10C  may be substantially analogous to the attachment system  500  described above with respect to  FIGS. 5A-5D . For example, the attachment system  1000  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  1000  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 5A-5D , the attachment system  1000  may include: lug  1004 ; cavity  1006 ; cavity entrance  1007 ; catch member  1008 ; ramp  1010 ; biasing springs  1009 ; friction elements  1012 ; port  1016 ; openings  1018 ; band  1024 ; insert portion  1028 ; and apertures  1032 . 
       FIG. 10A  illustrates an exploded view of the attachment system  1000 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  500 , the cavity  1006  of the attachment system  1000  may have a substantially uniform cross-dimensional area. This may allow the insert portion  1028  to be received within the cavity  1006  substantially free of any retention members and/or other protrusions or other features of the cavity  1006 . 
     The attachment system  1000  may include plates  1036 . The plates  1036  may include a pattern of fingers  1037 . The apertures  1032  may be configured to receive the pattern of fingers  1037  to couple the plate  1036  to the insert portion  1028 . In some instances, the plates  1036  may be a pair of plates disposed on external opposing surfaces of the insert portion  1028 . This may allow the pattern of fingers  1037  of one of the pair of plates to be interposed with the pattern of fingers  1037  of another of the pair of plates at a position within the insert portion  1028 . To facilitate the foregoing, the pattern of fingers  1037  may be received at non-adjacent ones of the apertures  1032 . 
       FIG. 10B  illustrates a top view of the assembled attachment system  1000  of  FIG. 10A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  1028  may be placed within the cavity  1006  in order to non-separably interlock the band  1024  with the lug  1004 . Notably, the insert portion  1028  may be substantially disposed within the cavity  1006  such that the various components described herein to facilitate the non-separable interlock of the band  1024  and the lug  1004  (e.g., the plates  1036 ) may be concealed from view in the assembled state. In this regard, the attachment system  1000  may non-separably interlock the band  1024  and the lug  1004  in a manner that maintains the aesthetic properties of the attachment system  1000 . 
       FIG. 10C  is a cross-sectional view of the attachment system  1000 , taken along line O-O of  FIG. 10B . In this regard, as illustrated, the band  1024  may be non-separably interlocked with the lug  1004 , according to the embodiments described herein. In the assembled configuration, the insert portion  1028  may be disposed within the cavity  1006 . The plates  1036  may be disposed within the cavity  1006  and adjacent the insert portion  1028 . For example, each of the pair of plates  1036  may be disposed adjacent opposing external surfaces of the insert portion  1028 . In turn, the pattern of fingers  1037  of each of the plates  1036  may be disposed within the apertures  1032 . 
     In one implementation, the plates  1036  may contact a surface of the cavity  1006 . For example, as shown in  FIG. 10C , at least a portion of the plates  1036  may extend beyond a perimeter of the insert portion  1028 . A welded connection may be formed between the plates  1036  and the cavity  1006 . The welded connection may be operative to non-separably interlock the band  1024  and the lug  1004 . For example, the welded connection between the plates  1036  and the cavity  1006  may non-separably interlock the plates  1036  and the cavity  1006 . This may allow the pattern of fingers  1037  of the plates  1036  (e.g., which are received by apertures  1032 ) to provide a structural barrier that restricts the movement of the band  1024  relative to the lug  1004 . Additionally or alternatively, an adhesive layer may be applied within the cavity  1006  to couple the plate  1036  to the cavity  1006 . 
       FIGS. 11A-11C  illustrate various views and components of an attachment system  1100 , according to one or more embodiments of the present disclosure. The attachment system  1100  shown and described with respect to  FIGS. 11A-11C  may be substantially analogous to the attachment system  800  described above with respect to  FIG. 8A - FIG. 8C . For example, the attachment system  1100  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  1100  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 11A-11C , the attachment system  1100  may include: lug  1104 ; cavity  1106 ; cavity entrance  1107 ; catch member  1108 ; ramp  1110 ; biasing springs  1109 ; friction elements  1112 ; port  1116 ; openings  1118 ; band  1124 ; insert portion  1128 ; apertures  1132 ; studs  1140 ; sleeve  1170 ; sleeve cavity  1172 ; sleeve inner surface  1174 ; and tabs  1176 . 
       FIG. 11A  illustrates an exploded view of the attachment system  1100 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  800 , the attachment system  1100  may include an insert portion  1128  that may be vertically aligned with the friction elements  1112 . By way of particular example, the insert portion  1128  may extend through the sleeve  1170  such that the apertures  1132  may be vertically aligned with the friction elements  1112  (e.g., the apertures  1132  and the friction elements  1112  may be positioned along a common axis). 
     The friction elements  1112  may include shafts  1120 . The shafts  1120  may extend from a surface of the friction elements  1112  and into the lug  1104  to engage the insert portion  1128 . For example, the shafts  1120  may be received by the apertures  1132  of the insert portion  1128 . The dispositions of the shafts  1120  may non-separably interlock the band  1124  and the lug  1104  by providing a structural barrier that restricts the movement of the band  1124  relative to the lug  1104 . 
     To facilitate the foregoing, at least a subset of the friction elements  1112  may include receiving recesses  1122 . The receiving recesses  1122  may be configured to receive a portion of the shafts  1120  that extend through the apertures  1132 . The receiving recesses  1122  may also be configured to receive studs  1140  in a configuration in which the pins  1136  are disposed within insert portion  1128 . 
       FIG. 11B  illustrates a top view of the assembled attachment system  1100  of  FIG. 11A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  1128  may be received by the sleeve  1170  in order to non-separably interlock the band  1124  with the lug  1104 . The insert portion  1128  may be dimensioned such that an external surface of the band  1124  and an external surface of the sleeve  1170  may be substantially flush in a state in which the insert portion  1128  is received by the sleeve  1170 . In this regard, the attachment system  1100  may non-separably interlock the band  1124  and the lug  1104  in a manner that maintains the aesthetic properties of the attachment system  1100 . 
       FIG. 11C  illustrates a cross-sectional view of the attachment system  1100 , taken along line P-P of  FIG. 11B . In this regard, as illustrated, the band  1124  may be non-separably interlocked with the lug  1104  according to the embodiments described herein. In the illustrated configuration, the insert portion  1128  may be disposed within the cavity  1106  such that the insert portion  1128  is vertically aligned with the friction elements  1112 . The vertical alignment of the insert portion  1128  and the friction elements  1112  may allow the apertures  1132  to receive pins  1136  and shafts  1120 . The receipt of the pins  1136  and the shafts  1120  may non-separably interlock the band  1124  and the lug  1104 . 
     Accordingly, the pins  1136  and the shafts  1120  may each facilitate the non-separable interlock of the band  1124  and the lug  1104 . For example, the pins  1136  and the shafts  1120  may form a barrier between a portion of the insert portion  1128  and the cavity entrance  1107  to restrict movement of the band  1124  relative to the lug  1104 . Additionally or alternatively, an adhesive layer may be applied within the lug  1104  to non-separably interlock the lug  1004  with the band  1124 . 
       FIGS. 12A-12C  illustrate various views and components of an attachment system  1200 , according to one or more embodiments of the present disclosure. The attachment system  1200  shown and described with respect to  FIGS. 12A-12C  may be substantially analogous to the attachment system  1000  described above with respect to  FIGS. 10A-10D . For example, the attachment system  1200  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  1200  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 10A-10D , the attachment system  1200  may include: lug  1204 ; cavity  1206 ; cavity entrance  1207 ; catch member  1208 ; ramp  1210 ; biasing springs  1209 ; friction elements  1212 ; port  1216 ; openings  1218 ; band  1224 ; insert portion  1228 ; apertures  1232 ; plates  1236 ; pattern of fingers  1237 ; retention members  1244 ; and grooves  1248 . 
       FIG. 12A  illustrates an exploded view of the attachment system  1200 , according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  1000 , the attachment system  1200  may include pins  1238  having studs  1240 . The plate  1236  may contain bores  1222  that are configured to receive the studs  1240 . Accordingly, the pins  1238  may be disposed within the apertures  1232  such that the studs  1240  extend from an external surface of the insert portion  1228 . In this manner, the pins  1238  may extend from the external surface of the insert portion  1228  to engage a surface of the cavity  1206 . 
       FIG. 12B  illustrates a top view of the assembled attachment system  1200  of  FIG. 12A , according to one or more embodiments of the present disclosure. By way of illustration, the insert portion  1228  may be placed within the cavity  1206  in order to non-separably interlock the band  1224  within the lug  1204 . The insert portion  1228  may be substantially disposed within the cavity  1206  such that the various components described herein to facilitate the non-separable interlock of the band  1224  and the lug  1204  (e.g., including the plates  1236 ) may be concealed from view in the assembled state. In this regard, the attachment system  1200  may non-separably interlock the band  1224  and the lug  1204  in a manner that maintains the aesthetic properties of the attachment system  1200 . 
       FIGS. 12C-12E  illustrate various cross-sectional views of the attachment system  1200 . In particular,  FIG. 12C  is a cross-sectional view of the attachment system  1200 , taken along line Q-Q of  FIG. 12B ;  FIG. 12D  is a cross-sectional view of the attachment system  1200 , taken along line R-R of  FIG. 12B ; and  FIG. 12E  is a cross-sectional view of the attachment system  1200 , taken along line S-S of  FIG. 12B . In this regard, as illustrated, the band  1224  may be non-separably interlocked with the lug  1204  in a manner substantially analogous to that of attachment system  200  depicted in  FIG. 2A - FIG. 2D . For example, insert portion  1228  may be disposed within the cavity  1206  such that the retention members  1244  may retain the pins  1238 . Additionally or alternatively, a welded connection may be formed between the plates  1236  and the lug  1204  to non-separably interlock between the band  1224  and the lug  1204 . 
     As depicted in  FIGS. 12C-12E , the bores  1222  of the plates  1236  may be through holes. In this regard, in the assembled configuration, the studs  1240  may extend from an external surface of the insert portion  1228  and through one of the bores  1222  to engage a surface of the cavity  1206 . For example, the studs  1240  may be received by the grooves  1248 . The plates  1236  may have a greater material stiffness than the insert portion  1228 . In this manner, the plates  1236  may structurally reinforce the insert portion  1228  where the studs  1240  engage with the grooves  1248 . 
       FIGS. 13A-13E  illustrate various views and components of an attachment system  1300 , according to one or more embodiments of the present disclosure. The attachment system  1300  shown and described with respect to  FIGS. 13A-13B  may be substantially analogous to the attachment system  200  described above in relation to  FIGS. 2A-2D . For example, the attachment system  1300  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  1300  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  1300  may include: lug  1304 ; cavity  1306 ; cavity entrance  1307 ; catch member  1308 ; ramp  1310 ; biasing springs  1309 ; friction elements  1312 ; port  1316 ; openings  1318 ; band  1324 ; insert portion  1328 ; apertures  1332 ; pins  1336 ; and grooves  1348 . 
       FIG. 13A  illustrates an exploded perspective view of the attachment system  1300  according to one or more embodiments of the present disclosure. Notwithstanding the foregoing similarities to the attachment system  200 , the lug  1304  may be an over-molded component. It will be appreciated that the lug  1304  may be an over-molded attachment structure, housing, or other like component. For example, the lug  1304  may be formed from an injection moldable plastic that is molded over the band  1324 . In this regard, the lug  1304  may be directly bonded to an external surface of the insert portion  1328  such that the band  1324  may be non-separably interlocked with the lug  1304 . In some instances, additional injection-moldable plastic layers may be bonded to an external surface of the lug  1304  to form a multi-layer lug structure which envelops the band  1324 . 
     To facilitate the bonding of the lug  1304  and the band  1324 , the attachment system  1300  may include one or more securement mechanisms. For example, the band  1324  may include apertures  1332 . In one embodiment, the injection-moldable plastic of the lug  1304  may be caused to flow into the apertures  1332  such that the injection moldable plastic may form a bond with the band  1324 . Additionally or alternatively, the attachment system  1300  may include pins  1336 . The pins  1336  may be positioned with the aperture  1332  such that the pins  1336  extend beyond a surface of the insert portion  1328 . In some instances, the lug  1304  may be molded over the pins  1336 . 
     In an alternative embodiment, the lug  1304  may include grooves  1348 . The grooves  1348  may be through portions that may be vertically aligned with one or more of the apertures  1332  (e.g., the grooves  1348  and the pins  1336  may be positioned along a common axis). Accordingly, in an assembled, over-molded configuration, the pins  1336  may be positioned within the grooves  1348  and the apertures  1332 . 
       FIG. 13B  illustrates a top view of the assembled attachment system  1300  of  FIG. 13A , according to one or more embodiments of the present disclosure. In the assembled configuration, lug  1304  is shown as being molded over the insert portion  1328 . In this regard, the attachment system  1300  may non-separably interlock the band  1324  and the lug  1304  in a manner that maintains the aesthetic properties of the attachment system  1300 . For example, the band  1324  may be directly bonded with the lug  1304  in a manner that is concealed from the user. 
       FIGS. 14A-14B  illustrate various views and components of example bands  1400   a  and  1400   b  (collectively referred to as “the example bands”), according to one or more embodiments of the present disclosure. The example bands shown and described with respect to  FIGS. 14A-14B  may be substantially analogous to the band  136  described above with respect to  FIG. 1 . For example, the example bands may non-separably interlock with a lug, attachment structure, housing, or other like feature (e.g., such as the lug  132  depicted in  FIG. 1 ). In this regard, the example bands may be a component of an attachment system (e.g., such as the attachment system  104  depicted in  FIG. 1 ) that is operative to attach a consumer product to a user. Specific shapes and orientations are described below with respect to the example bands and the various components of the example bands. However, the disclosed shapes and orientations of the example bands, and any associated components, are not limiting and are used as examples. Accordingly, similar shapes and orientations of the example bands, and the associated components, described below with respect to  FIGS. 14A-14B , may be used with the various embodiments of the attachment system described herein. 
       FIG. 14A  illustrates an assembled view of the band  1400   a . The band may be a strap or other feature attachable to a user. The band  1400   a  may have an insert portion  1402   a  configured to non-separably interlock with a lug. As shown in  FIG. 14A , insert portion  1402   a  may include two prongs. The lug may an attachment structure, housing, or other structure configured for removable engagement with a consumer product. The band  1400   a  may include a plate  1404 . The plate  1404  may be positioned within the band  1400   a  such that the band  1400   a  envelops the plate  1404 . The plate  1404  may have a greater material stiffness than the band  1400   a . In this regard, the plate  1404  may structurally reinforce a portion of the band  1400   a.    
     In some instances, the plate  1404  may include apertures  1406  that are vertically aligned with the insert portion  1402   a . For example, the apertures  1406  may be vertically aligned with one or more through portions of the insert portion  1402   a  that may be configured to receive one or more elements to non-separably interlock the band  1400   a  and lug (e.g., such as lug  132  depicted in  FIG. 1 ). In some instances, additional structural elements may be disposed within the band  1400   a , including additional plates disposed within the band  1400   a  in spaced relation with the plate  1404 . 
       FIG. 14B  illustrates an assembled view of the band  1400   b . The band  1400   b  may have an insert portion  1402   b  configured to non-separably interlock with a lug. As shown in  FIG. 14B , insert portion  1402   b  may include two prongs. The band  1400   b  may include plates  1420 . The plates  1420  may be disposed within the band  1400   b  such that the band  1400   b  envelops the plates  1420 . The plates  1420  may be positioned within the band  1400   b  in spaced relation to one another and provide structural reinforcement to the band  1400   b.    
     The band  1400   b  may include reinforcement bars  1424 . The plates  1420  may be connected to, or integrally formed with, the reinforcement bars  1424 . The reinforcement bars  1424  may be disposed within the band  1400   b  to provide structural reinforcement to the insert portion  1402   b . For example, the reinforcement bars  1424  may have a greater material stiffness than the band  1400   b.    
     In some instances, the reinforcement bars  1424  may include apertures  1428 . The apertures  1428  may be vertically aligned with a through portion of the insert portion  1402   b . In some embodiments, the apertures  1428  may be configured to engage one or more features to facilitate the non-separable interlock of the band  1400   b  one or more of the lugs described herein. In this regard, the reinforcement bars  1424  may be configured to reinforce the non-separable interlock of the band  1400   b  and the lug. As shown in  FIG. 14B , the plates  1420  may be coupled with the reinforcement bars  1424  to provide additional structural reinforcement of the band  1400   b  of the insert portion  1402   b . In another embodiment, the plates  1420  may be integrally formed with the reinforcement bars  1424  such that the plates  1420  and the reinforcement bars  1424  form a single, unitary component. In some instances, the reinforcement bars  1424  may define a portion of an outer surface of the insert portion  1402   b.    
       FIGS. 15A-15B  illustrate exploded views of an attachment system  1500 , according to one or more embodiments of the present disclosure. The attachment system  1500  shown and described may be substantially analogous to the attachment system  200  described above with respect to  FIG. 2 . For example, the attachment system  1500  may be configured for removable engagement with a consumer product (e.g., such as the consumer product  108  depicted in  FIG. 1 ). Further, the attachment system  1500  may include a substantially flexible component and a substantially rigid component. In this regard, analogous to the components described in relation to the embodiments of  FIGS. 2A-2D , the attachment system  1500  may include: lug  1504 ; cavity  1506 ; cavity entrance  1507 ; catch member  1508 ; ramp  1510 ; biasing springs  1509 ; friction elements  1512 ; port  1516 ; opening  1518 ; band  1524 ; insert portion  1528 ; apertures  1532 ; pins  1536 ; studs  1540 ; retention members  1544 ; and grooves  1548 . 
     Notwithstanding the foregoing similarities to the attachment system  200 , the attachment system  1500  may include one or more structural members configured to reinforce the band  1524 . For example, in the embodiment depicted in  FIG. 15 , the attachment system  1500  may include plate  1570 . The plate  1570  may be substantially analogous to the plate  1404  described with respect to  FIG. 14A . The plate  1570  may be positioned within the band  1524  such that the band envelops the plate  1570 . The plate  1570  may have a greater material stiffness than the band  1524 , thereby providing structural reinforcement to the band  1524 . 
     In some embodiments, the plate  1570  may be disposed within the insert portion  1528  to structurally reinforce the non-separably interlocked connection between the band  1524  and the lug  1504 . For example, the plate  1570  may include holes  1574 . The holes  1574  may be vertically aligned with apertures  1532 . In this regard, pins  1536  may be received by the apertures  1532  and the holes  1574  to facilitate the non-separable interlock between the band  1524  and the lug  1504 . 
     In another embodiment, the plate  1570  may be configured to non-separably interlock the lug  1504  and the band  1524 . For example, plate  1570  may include tab  1578 . Tab  1578  may be coupled to, or integrally formed with, the plate  1570  (e.g., such that the plate  1570  and the tab  1578  may be a single, unitary component). The tab  1578  may extend beyond a perimeter of the insert portion  1528  to define a protrusion. The tab  1578  may be engaged with a portion of the lug  1504  to non-separably interlock the band  1524  and the lug  1504 . For example, lug  1504  may include receiving socket  1582 . Receiving socket  1582  may be configured to receive the tab  1578 . In one embodiment, a welded connection may be formed between the tab  1578  and the receiving socket  1582  to non-separably interlock the band  1524  and the lug  1504 . 
       FIG. 16  illustrates an example reinforcement system  1600 . Reinforcement system  1600  may be configured to join a substantially flexible component and a substantially rigid component in a manner that maintains the aesthetic characteristics of the flexible component. For example, the reinforcement system  1600  may be configured to structurally reinforce the flexible component in a manner that maintains at least a portion of the band substantially free of defects or other imperfections indicative of bonding a flexible band to a reinforcement structure. 
     By way of particular example, the reinforcement system  1600  may include band  1604 . The band  1604  may be a woven band that may be formed from a variety of appropriate materials, including nylons and other appropriate polymers. In this regard, the band  1604  may be configured to melt upon the localized application of heat. In one embodiment, the band  1604  may be a substantially hollow structure having a cavity  1608 . 
     The reinforcement system  1600  may also include a metal sheet  1612 . The metal sheet  1612  may be disposed within the cavity  1608  such that the band  1604  surrounds at least a portion of the metal sheet  1612 . The metal sheet  1612  may be constructed from any appropriate material that is electrically conductive. In particular, the metal sheet  1612  may be any conductive material that generates a sufficient quantity of heat upon the induction of an electric current across a portion of the metal sheet  1612 . Possible materials may include silver, copper, gold, aluminum, and/or other appropriate metals or metal alloys. 
     Electrical current is induced across at least a portion of the metal sheet  1612 . As depicted in  FIG. 16 , the metal sheet  1612  may include a first end  1616  having a first electric potential and a second end  1620  having a second electric potential. The first electric potential and the second electric potential may be different such that electrical current may flow between the first end  1616  and the second end  1620  or the second end  1620  and the first end  1616 . For example, the metal sheet  1612  may be connected to an external power source in order to cause the first end  1616  to have the first electric potential and the second end  1620  to have the second electric potential. 
     The inducement of electrical current between the first end  1616  and the second end  1620  may generate heat. The generation of heat by the metal sheet  1612  may melt at least a portion of the band  1604 . When the band  1604  is in a melted state, the melted portion may be manipulated to facilitate the joining of the band  1604  and the metal sheet  1612 . 
     The metal sheet  1612  may include one or more features to facilitate the attachment of the band  1604  to the metal sheet  1612 . For example, the metal sheet  1612  may include securement mechanisms  1624 . The securement mechanisms  1624  may be holes, apertures, recesses, and/or other features of the metal sheet  1612 . In this regard, in one implementation, the securement mechanisms  1624  may be through portions. Accordingly, the securement mechanisms  1624  may be configured to receive a portion of the band  1604  to facilitate the joining of the band  1604  with the metal sheet  1612 . For example, a melted portion of the band  1604  may be caused to flow into and/or through one or more of the securement mechanisms  1624  to join the band  1604  and the metal sheet  1612 . 
     The band  1604  may be configured to receive a force “F” on opposing external surfaces of band  1604 . The force “F” applied at both of the opposing external surfaces of the band  1604  may compress the band  1604  relative to the metal sheet  1612 . In one implementation, the force may be received from a non-metallic object. 
     To facilitate the reader&#39;s understanding of the various functionalities of the embodiments discussed herein, reference is now made to the flow diagrams in  FIGS. 17-20 , which illustrates processes  1700 ,  1800 ,  1900 , and  2000 , respectively. While specific steps (and orders of steps) of the methods presented herein have been illustrated and will be discussed, other methods (including more, fewer, or different steps than those illustrated) consistent with the teachings presented herein are also envisioned and encompassed with the present disclosure. 
     In this regard, with reference to  FIG. 17 , process  1700  relates generally to assembling an attachment system for a consumer product. The process  1700  may be used in conjunction with the consumer product described herein (e.g., consumer product  108 ). At operation  1704 , a sleeve may be inserted into a channel of a lug. The lug may an attachment structure, housing, or other structure configured for removable engagement with a consumer product. For example and with reference to  FIG. 8A , the sleeve  870  may be inserted into the cavity  806  via the cavity entrance  807 . In some cases, the sleeve  870  may include tabs  876 . In this manner, the sleeve  870  may be inserted into the cavity  806  such that at least a portion of tabs  876  engage an interior surface of the cavity  806 . 
     At operation  1708 , the sleeve may be welded to the lug. For example and with reference to  FIG. 8A , a welded connection may be formed between a portion of the sleeve  870  and the lug  804 . For example, a welded connection may be formed between the tabs  876  and an interior surface of the cavity  806 . The welded connection between the sleeve  870  and the lug  804  may non-separably interlock the sleeve  870  to the lug  804 . 
     At operation  1712 , a band may be advanced into the sleeve to non-separably interlock the band and the sleeve. For example and with reference to  FIG. 8A , the band  824  may be advanced into the sleeve  870 . In one embodiment, the band  824  may be coupled with one or more engagement members (e.g., such as pins  836 ) that are configured to non-separably interlock the band  824  to the sleeve  870 . For example, the pins  836  may be disposed within the band  824  such that a portion of the pins  836  extend beyond a perimeter of the band  824  for engagement with the sleeve inner surface  874 . The engagement of the pins  836  may form a friction or interference fit with the sleeve inner surface  874  that facilitates non-separably interlocking the band  824  with the sleeve  870 . Additionally or alternatively, an adhesive layer may be applied between the band  824  and the sleeve  870  to non-separably interlock the band  824  and the sleeve  870 . 
     At operation  1716 , a friction element may be secured to an outer surface of the lug. The friction element may be an alignment feature configured to maintain a spacing between the lug  804  and an associated consumer product. For example and with reference to  FIG. 8A , the friction elements  812  may be secured to the lug  804  at the openings  818 . Various structures may be employed to secure the friction elements  812  to the lug  804 , including flanges, anchor pins, shafts, and adhesive layers, according to the embodiments described herein. 
       FIG. 18  illustrates a process  1800  that relates generally to reinforcing a strap. For example, the process  1800  may be used to create a reinforced strap, such as band  1400   a  depicted in  FIG. 14A . In this regard, at operation  1804 , a woven strap may be placed adjacent a metal sheet. For example and with reference to  FIG. 16 , the woven strap  1604  may be placed adjacent to the metal sheet  1612 . In some instances, the metal sheet  1612  may include one or more securement mechanisms, such as a hole, recess, or other feature that may be configured to facilitate the attachment of the metal sheet  1612  to the woven strap  1604 . 
     At operation  1808 , a flow of electrical current may be induced across a segment of the metal sheet. For example and with reference to  FIG. 16 , an electrical current may be induced between first end  1616  and the second  1620 . The inducement of electrical current may be configured to generate heat at the metal sheet  1612 . The heat may melt at least a portion of the woven strap  1604  disposed adjacent to the metal sheet  1612 . 
     At operation  1812 , the melted portion of the woven strap may be caused to flow toward a securement mechanism for bonding of the woven strap and the metal sheet. For example and with reference to  FIG. 16 , the application of force “F” on the adjacent woven strap  1604  may cause the melted portion of the woven strap  1604  to flow toward the one or more securement mechanisms  1624  of the metal sheet  1612 . For example, the melted portion of the woven strap  1604  may flow toward the securement mechanism  1624  to facilitate the bonding of the woven strap  1604  and the metal sheet  1612 . The woven strap  1604  may be joined with the metal sheet  1612  in a manner that may cause at least a portion of the woven strap  1604  (e.g., a portion of the woven strap  1604  opposite the metal sheet  1612 ) to be substantially free from surface defects. 
       FIG. 19  illustrates a process  1900  that relates generally to assembling an over-molded attachment system. At operation  1904 , a band may be placed within a form. For example and with reference to  FIG. 13A , the band  1324  may be placed within a form that may be constructed to define the shape of a lug that may envelop a portion of the band  1324 . In some instances, the band  1324  may include a securement mechanism, for example, including a recess, pin, or other structure that may be configured to facilitate the joining of the band  1324  and the lug. The lug may an attachment structure, housing, or other structure configured for removable engagement with a consumer product. 
     At operation  1908 , material may be caused to flow into the form to define a lug enveloping a portion of the band. For example and with reference to  FIG. 13A , an injection-moldable plastic may be caused to flow into the form to envelop a portion of the band  1324  (e.g., the portion of the band  1324  disposed within the form). The injection-moldable plastic may be cooled and hardened. This may cause the injection-moldable plastic to bond to the band  1324  and create the lug  1304 . 
     At operation  1912 , an aperture may be created within a region of the band that is vertically aligned with an opening of the lug. For example and with reference to  FIG. 13A , the apertures  1332  may be created within the band  1324  such that the apertures  1332  and the opening  1318  are positioned along a common axis. This may be accomplished by cutting or otherwise removing excess material from the band  1324 . 
     At operation  1916 , a friction element may be positioned within the aperture and the opening. The friction element may be an alignment feature configured to maintain a spacing between the lug  804  and an associated consumer product. For example and with reference to  FIG. 13A , the friction elements  1312  may be secured to the lug  1304  at the opening  1318 . Various structures may be employed to secure the friction elements  1312  to the lug  1304 , including flanges, anchor pins, shafts, welded connections, and adhesive, according to the embodiments described herein. 
       FIG. 20  illustrates a process  2000  that relates generally to assembling an attachment system for use with a consumer product. At operation  2004 , an aperture may be created in a band. For example and with reference to  FIG. 6A , the apertures  632  may be created in the band  624  at insert portion  628 . The apertures  632  may be created by cutting or otherwise removing excess material from the band  624 . 
     At operation  2008 , an insert portion may be slid into a cavity of the lug. The lug may be an attachment structure, housing, or other structure configured for removable engagement with a consumer product. For example and with reference to  FIG. 6A , the insert portion  628  may be slid into the cavity  606  via cavity entrance  607 . The insert portion  628  may be slid into the cavity  606  such that the apertures  632  may be vertically aligned with the opening  618 . 
     At operation  2012 , a pin may be advanced through the opening and the aperture to non-separably interlock the band and the lug. For example and with reference to  FIG. 6A , in one embodiment, the ultrasonic pins  636  may be advanced through the openings  618  and the apertures  632  to non-separably interlock the band  624  and the lug  604 . In some instances, a high-frequency ultrasonic vibration may be applied to the ultrasonic pins  636  such that a portion of the band  624  (e.g., a surface of the apertures  632  adjacently disposed to the ultrasonic pins  636 ) may be caused to melt. The melting and subsequent cooling of the melted portion of the band  624  may cause the band  624  to bond to a surface of the ultrasonic pins  636  (e.g., the melted portion of the band  624  may bond to a knurled surface of the ultrasonic pins  636 ). 
     At operation  2016 , a friction element may be secured to an outer surface of the lug. The friction element may be an alignment feature configured to maintain a spacing between the lug  804  and an associated consumer product. The friction element may be configured to engage a consumer product. For example and with reference to  FIG. 6A , the friction elements  612  may be secured to the lug  604  at the openings  618 . Various structures may be employed to secure the friction elements  612  to the lug  604 , including flanges, anchor pins, shafts, and adhesive layers, according to the embodiments described herein. In one implementation, the friction elements  612  may protrude from an outer surface of the lug  604  for engagement with a consumer product. 
       FIG. 21  is a block diagram illustrating example components, such as, for example, hardware components of a consumer product  2100  according to one or more embodiments of the present disclosure. The consumer product  2100  may be similar to the consumer product  108  described above. Although various components of the consumer product  2100  are shown, connections and communication channels between each of the components are omitted for simplicity. As previously discussed, the consumer product may be a wearable device such as a watch or glasses, a tablet computing device, a telecommunications device such as a phone, a laptop computer or the like, a remote control, and so on. 
     In a basic configuration, the consumer product  2100  may include at least one processor  2104  or processing unit and a memory  2108 .
