Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a nonprovisional patent application of and claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 62/048,248, filed on Sep. 9, 2014, and titled “Attachment Systems for Consumer Products,” the disclosure of which is hereby incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The present disclosure is generally directed to an attachment system for coupling two objects together and, more specifically, to an attachment system including a captive button with one or more spring bars. 
     BACKGROUND 
     Consumer products such as watches, cameras, phones, purses, and glasses may include one or more accessories attached thereto. The manner in which they are attached may be widely varied. However, they typically suffer from similar, if not the same, drawbacks. For example, many consumer products typically do not include user-friendly attachment systems. Some may require special tools and others may even require taking the consumer product into a shop in order to remove, fix or replace the accessories. 
     In one example, wristwatches typically include a case and a band. The case carries the watch mechanisms including the watch face. The band extends away from the case so that it can wrap around the wrist of a user. The band may be integral with the case. However, in most cases, the band is a separate part that is attached to the case. For example, the case may include a pin that captures the band thereby attaching the band to the case. In order to detach the band from the case, the pin needs to be removed. In some instances, band removal can be accomplished with a special tool. However, in many cases, the user may need to visit a specialty store or have the assistance of technician in order to remove the band. 
     In another example, a pair of glasses, such as, electronic glasses, sunglasses and the like, may have temples or stems that extend from a frame. These temples or stems may be coupled to the frames by a screw, a pin or other such mechanism. However, like the wristwatch, a special tool may be required to remove and/or secure the temples or stems to/from the frame. 
     In still yet another example, other electronic devices may be coupled to a lanyard or other type of band. For example a camera, a remote control, a game controller and the like may have a lanyard that is attached to a housing. However, it may be difficult to attach the lanyard to the housing as a portion of the lanyard is typically required to be inserted into a small opening within the housing. In this example, as with the other examples discussed above, the lanyard, accessory, object or article may not be attached to the electronic device or consumer product in a manner that facilitates user removal of the component. 
     It is with respect to these and other general considerations that embodiments have been made. Although relatively specific problems have been discussed, it should be understood that the embodiments should not be limited to solving the specific problems identified in this background. 
     SUMMARY 
     Embodiments described herein may be directed to an attachment system for coupling an accessory or component to a consumer product. The attachment system may include a captive locking mechanism that may be incorporated with the accessory or non-product side attachment assembly. The captive locking mechanism may be configured to engage a corresponding feature of a product-side attachment assembly of a consumer product. For example, if the consumer product is a wearable electronic device, such as a watch or other wrist-wearable device, the attachment system may be configured to attach a band or band assembly to the body or housing of the wearable electronic device. In some embodiments, the attachment system may include a captive locking mechanism integrated or incorporated with a removable module of the accessory. The captive locking mechanism may include one or more spring-bar components that anchor the engagement mechanism in a recess or feature formed in the removable module. 
     The attachment system may also include a release mechanism that may be incorporated with the product-side attachment assembly of a consumer product. The release mechanism may be configured to disengage or unlock the captive locking mechanism and facilitate removal of the removable module of the accessory. As described in more detail below, in some embodiments, the release mechanism may be captive or otherwise retained in the body of the device and may include one or more spring-bar components that anchor the release mechanism in a recess or featured formed into the body of the device. 
     Some example embodiments are directed to an attachment system of a consumer product. The system may include a removable module that is configured to slidably engage with a mating feature of the consumer product. The removable module may have an aperture formed therein for containing a locking mechanism. The locking mechanism may include a catch member that is disposed within the aperture of the removable module and configured to protrude from a first surface of the removable module. The locking mechanism may also include a ramp member disposed within the aperture and configured to protrude from a second surface of the removable module that is opposite to the first surface. One or more spring bars may be positioned within and span across a width of the aperture. A first spring may be coupled between the spring bar and the ramp member. The first spring may bias the ramp member away from the spring bar. A second spring may be coupled between the ramp member and the catch member. The second spring may bias the catch member away from the ramp member. In some embodiments, the consumer product is a wearable electronic device, and the removable module couples a band strap to the wearable electronic device. 
     In some embodiments, the catch member is configured to protrude outward from the aperture and engage a recess formed in the mating feature of the consumer product to retain the removable module with respect to the consumer product. In some cases, when the removable module is not engaged with the mating feature of the consumer product, the catch member is flush with or below the first surface, and a portion of the ramp member extends beyond the second surface. In some cases, when the removable module is partially engaged with the mating feature of the consumer product, the catch member is flush or below the first surface, and the ramp member is flush or below the second surface. In some cases, when the removable module is fully engaged with the mating feature of the consumer product, a portion of the catch member extends beyond the first surface and engages a recess formed in the mating feature, and the ramp member is flush or below the second surface. 
     In some embodiments, the spring bar includes a barrel portion and a spring-loaded protrusion that extends out from an end of the barrel portion. The spring-loaded protrusion may be configured to engage corresponding recess formed in a wall of the aperture. 
     In some embodiments, a retaining feature is formed within aperture and limits the outward movement of the ramp member. The retaining feature may include a protrusion that projects inward from a wall of the aperture. 
     In some embodiments, the ramp member includes a ramp-retaining feature that engages a catch-retaining of the catch member. In some cases, an engagement between the ramp-retaining feature and the catch-retaining feature limits the outward movement of the catch member. 
     In some embodiments, the mating feature of the consumer product includes an undercut or feature geometry that helps to retain the removable module within the feature. In some cases, the mating feature of the consumer product has an opening width at an opening of the feature and a maximum width within the feature being greater than the opening width. Similarly, the removable module may have a first portion having a first thickness that is smaller than the opening width of the opening and a second thickness that is less than the maximum width of the feature and greater than the opening width. In some cases, the opening width of the mating feature is configured to limit the movement of the removable module in a direction perpendicular to opening. 
     Some example embodiments are directed to an attachment system of an consumer product including a release mechanism for disengaging the removable module. The system may include a housing of the consumer product having a channel formed therein. The system may also include a removable module that is configured to slidably engage with the channel of the housing. The removable module may include a catch member that retains the removable module within the channel. The system may also include a release mechanism that is configured to release the catch. The release mechanism may be disposed within an aperture in a wall of the channel. The release mechanism may include a button member at least partially disposed within the aperture and configured to move up and down within the aperture. The release mechanism may also include a spring bar positioned within and spanning across a width of the aperture. The spring bar may be received by a feature formed in the button member and the spring bar may limit motion of the button member. In some cases, the feature formed in the button member is a slotted hole and the spring bar guides the button member by slidably engaging the slotted hole. 
     In some embodiments, a spring may be positioned between the button member and a feature formed into the body. The spring may be configured to bias the button away from the channel. In some embodiments, the button member includes an actuation portion and a plunger portion. The plunger portion may be configured to disengage the catch member from a recess when the actuation portion is pushed. the recess may be formed in a wall of the channel. In some embodiments, the plunger portion is configured to be flush or extend into the recess when the button member is pushed. 
     Some example embodiments are directed to a method of installing or assembling a locking mechanism in a removable module of an accessory. The method may include positioning at least one spring bar with respect to a ramp member. A first spring may be disposed between the ramp member and the at least one spring bar. The method also includes positioning a catch member with respect to the ramp member. A second spring may be disposed between the catch member and the ramp member. The at least one spring bar of the locking mechanism may be compressed and the components may be inserted into an aperture formed in the removable module. The at least one spring bar may be engaged within a recess formed in a wall of the aperture. 
     Some example embodiments are directed to a method of attaching the accessory into a consumer product using the removable module. The removable module of the accessory may be inserted into a channel of the consumer product. A side force may be applied to the removable module to slide the removable module further into the channel. As the removable module is slid into the channel, the ramp member of the locking mechanism may be compressed using the channel. The catch member of the locking mechanism may engage with a recess formed into a wall of the channel. Engagement between the catch member and the recess may prevent the removable module from sliding within the channel. In some cases, as the ramp member is compressed, a spring provides an outward bias force on the catch member pushing the catch member toward a wall of the channel. When the catch member engages the recess, the outward bias force may maintain the catch member in an extended position. 
     Some example embodiments are directed to a method of detaching the accessory from the consumer product. For example a release mechanism may be actuated by applying a force to an actuation portion of the release mechanism. The catch member may be expelled from the recess using a plunger portion that is coupled to the actuation portion of the release mechanism. A side force may be applied to the removable module to slide the removable module within the channel. The removable module may then be removed from the channel. In some cases, removing the removable module from the channel results in an extension of the ramp member from removable module. In some cases, removing the removable module from the channel results in the catch member being substantially flush with a surface of the removable module.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     Provided herein is an attachment system for a consumer product. The attachment system may include a removable module that interfaces with some portion of the consumer product. For example, the removable module may engage with a related or corresponding module, recess, aperture or component of, or associated with, the consumer product. When engaged, the removable module may be carried by the consumer product. For example, when the removable module is engaged with the consumer product, the module and the consumer product may become an integrated unit. In some cases, the removable module can extend the functionality of the consumer product. That is, the attachment system and/or the removable module can provide additional operability to the consumer product. Additionally or alternatively, the removable module may be used as an accoutrement to the consumer product. For example, the removable module may add an aesthetic or structural enhancement to the consumer product. Additionally or alternatively, the removable module may be configured to couple another object or article to the consumer product. For example, the object may be an accessory such as a cover, skin, plate, lanyard, band, strap, dock and/or the like. In all of these examples, the interface between the removable module and the consumer product may be a standard interface such that different functionality, accoutrements, and objects can be coupled to the consumer product. 
     The consumer product that may be used in conjunction with the attachment system can be widely varied. By way of example and not by way of limitation, the consumer product may be an electronic device, a mechanical device, an electromechanical device and the like. In one example, the consumer product is a portable consumer product. In another example, the consumer product is a wearable product. Additional and more specific examples of the consumer product include mobile phones, personal digital assistants, music players, mechanical timekeeping devices, electromechanical timekeeping devices, health monitoring devices, tablet computers, laptop computers, glasses (electronic or otherwise), portable storage devices and the like. Although the examples above include electronic devices, the attachment system of the present disclosure may be used with non-electronic devices. 
     The attachment system can also be widely varied. In one embodiment, the attachment system may have a tool-less design such that a special tool is not needed to connect and/or disconnect the attachment system from the consumer product. As a tool may not be required, the attachment system may be easy to use and intuitive. Additionally or alternatively, a tool or other component, such as a component of the consumer product to which the attachment system is coupled, may be configured to actuate a button or other component of the attachment system to secure and/or release the attachment system from the consumer product. 
     Although a tool may not be required to secure and/or release the attachment system from the consumer product, the attachment system of the present disclosure is robust and provides a retention force that enables the attachment system to be securely coupled to the consumer product. Although the attachment system is robust, as will be discussed below and shown in the figures, the attachment system may have a low profile thereby enabling the consumer product to maintain a desirable or particular shape. 
     As will also be described below, the attachment system of the present disclosure typically includes a product-side attachment assembly and a non-product side attachment assembly that can engage and disengage to and from one another. Each of these assemblies may, for example, include a lug portion that physically interface with one another in order to secure the two assemblies together. The assemblies may also releasably interface with one another in order to free the assemblies from each other. 
     The attachment system may include a captive locking mechanism that may be incorporated with the non-product side attachment assembly. The captive locking mechanism may be configured to engage a corresponding feature of a product-side attachment assembly of a consumer device. For example, if the consumer device is a wearable electronic device, such as a watch or other wrist-wearable device, the attachment system may be configured to attach a band assembly to the body of the wearable electronic device. The band assembly may include one or more straps and a clasp that can be used to secure the wearable electronic device to the wrist of a user. In this case, the attachment system may include a captive locking mechanism that is incorporated with the band assembly and is configured to engage a corresponding feature formed in or incorporated with the body of the wearable electronic device. In some cases, the locking mechanism secures or locks the band assembly to the body of the wearable electronic device. As described in more detail below, in some embodiments, the captive locking mechanism may include one or more spring-bar components that anchor the engagement mechanism in a recess or feature formed in a component of the band assembly. 
     The attachment system may also include a release mechanism that may be incorporated with the product-side attachment assembly of a consumer device. For example, if the consumer device is a wearable electronic device, a release mechanism may be integrated with or incorporated into the body of the device. The release mechanism may be configured to disengage or unlock the captive locking mechanism and facilitate removal of a band assembly or other component. As described in more detail below, in some embodiments, the release mechanism may be captive or otherwise retained in the body of the device and may include one or more spring-bar components that anchor the release mechanism in a recess or featured formed into the body of the device. 
     In some embodiments, the attachment system includes a removable module of the non-product assembly that mechanically or slidably engages/disengages a component of the consumer product. In one example, the component may be the housing or enclosure of the consumer product and the removable module may include a removable lug that forms part of a band assembly. In some cases, the band assembly includes at least one strap and a clasp that are configured to attach the consumer product to the wrist of a user. 
     In some embodiments, the removable module of the attachment system may be configured to be inserted into an opening on the consumer product. Once the removable module, has been inserted into the opening, the removable module may slide within the opening of the consumer product. For example, the consumer product may have a channel that is disposed on one or more sides of a housing of the consumer product. The channel may be configured to receive a portion, such as an end portion, of the removable module of the attachment system. Once the end portion of the removable module has been inserted into the channel, the removable module may slide further into the channel. The sliding motion of the removable module may continue until the removable module is secured or otherwise coupled to or within the channel. Just as the removable module is configured to slide into the channel of the consumer product, the removable module may also slide out of the channel of the consumer product. Thus, the removable module may be easily inserted into and removed from the consumer product. 
     In some embodiments, opening or channel of the attachment system may be shaped to retain the removable module. For example, the opening or channel may include an undercut or narrowed portion that mechanically engages the removable module to retain the removable module in the opening or channel. As such, when the removable module is placed within the receiving module of the consumer product, the removable module may be integrated (either partially or entirely) with the consumer product. 
     The attachment system may also be used to secure various accessories to the consumer product. For example, an accessory, article or object may be coupled or otherwise attached to the removable module of the attachment system. Further, the accessory, article or object may be used to secure the consumer product to a user. In some cases, the consumer product may be configured to receive multiple different bands, accessories and the like. The consumer product, and the associated bands, may each include a common node (e.g., a removable module) that couples to a corresponding node (e.g., an opening or channel) associated with the consumer product. Accordingly, the consumer product may have a plurality of accessories or bands that may be interchangeable thereby providing a user many different aesthetic looks for the consumer product. More specifically, the consumer product may be configured to receive a first band, and second band which is different than the first band. Further, each of the first band and the second band may include a common node that couples to, or is received by, a corresponding node in the consumer product. Thus, each band may be interchangeable with respect to one another and with other bands and/or accessories. 
     Furthering the example from above, a band assembly or strap may be removably coupled to the attachment system and may further be used to secure the consumer product to the user. Because the attachment system is removably coupled to both the housing of the consumer product and a band or strap, the attachment system itself, or the band or strap, may be interchangeable with numerous other bands having different materials, designs and configurations. 
     In one particular embodiment, the consumer product is a portable electronic device. More specifically, the consumer product is may be a wearable consumer product. A wearable consumer product is one that can be worn by or otherwise secured to a user. For example, the wearable electronic device may include, but is not limited to a wearable computer, a wearable watch, a wearable communication device, a wearable media player, a wearable health monitoring device, and/or the like. In cases such as these, the attachment system may be used to couple a band, a strap, a sleeve or various types of clothing to the wearable consumer product. For example, in the case of a wrist worn product, the removable module of the attachment system may couple the device to a band that can be wrapped around and secured to a user&#39;s wrist when the removable module is attached to the wearable product. It should be appreciated, however, that this embodiment is not a limitation. 
     In certain embodiments, the band, the attachment system and/or portions of each may be made up of a variety of different materials and/or configurations. In certain embodiments, the band and/or the attachment system, may be made from rubber, metal, woven fiber, leather, rubber overlaying a woven mesh, silicon, Milanese mesh, and so on. In some embodiments, a first band, or a first portion of a first band may be made up of a first material and a second bad, or a second portion of the first band, may be made from a second different material. The band may also be made up of a plurality of links with the attachment system forming one or more of the links. As such, the band may be resizable by, for example, adding or removing links. 
     In some embodiments, the band may be coupled to a portion of the attachment system using a mechanical joint. For example the band may be attached to a removable module such as a lug using one or more pins, holes, adhesives, screws, and the like. In some embodiments, the band may be co-molded or overmolded with at least a portion of the removable module or lug. In some embodiments, the band is integrally formed with a feature that functions as the removable module or lug. 
     These and other embodiments are discussed below with reference to  FIGS. 1-16 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
       FIGS. 1A-C  illustrate an exemplary attachment system  100  according to one or more embodiments of the present disclosure. The attachment system  100  may include a removable module  110  that interfaces with some portion of a consumer product  118 . The removable module  110  may, for example, engage with a housing  120  of the consumer product  118 . The housing  120  may include, for example: a housing portion of the consumer product, an extension of another part of the consumer product  118 , a separate part fixed to a portion of the housing of the consumer product, and the like. In certain embodiments, the housing  120  may be used as a housing for various consumer products, electronic devices, mechanical devices and the like. Accordingly, the housing  120  may be referred to a housing  120  throughout this disclosure. 
     Non-limiting examples of consumer products include electronic devices, mechanical devices and so on. Mores specific examples include but are not limited to, a tablet computer, a timekeeping device, a mobile telephone, a portable music player, a personal digital assistant, glasses and the like. As such, the component or housing  120  may have various dimensions and shapes based on the anticipated use of the housing  120 . Further, the housing  120  may include various openings and/or recesses (not shown) that may be used for buttons, display screens and the like. Depending on the intended use and desired durability of the housing  120 , the housing  120  may be made of stainless steel, aluminum, plastic, gold, glass, platinum, or other such materials and combinations thereof. 
     The removable module  110  can be widely varied. The removable module may, for example, extend the functionality of the consumer product  118  (e.g., adding operational modules, electrical systems and the like). The removable module  110  may be used as an accoutrement to the consumer product thereby enhancing aesthetics of the consumer product  118 . The removable module may also be configured to couple an object or other article to the consumer product  118 . For example, the object may be a cover, skin, plate, lanyard, band, strap, and/or the like. The interface may be standard interface such that different objects can be attached to the consumer product  118  via the attachment system  100 . 
     The removable module  110  may include a body  111  that is configured for insertion into a mating feature or channel  121  of the housing  120  of the consumer product  118 . For example,  FIG. 1A  shows the removable module  110  outside of the channel  121  and  FIG. 1C  shows the removable module  110  inserted within the channel  121 . When the removable module  110  is inserted into the channel  121 , the removable module  110  is engaged with or otherwise secured to the consumer product  118  such that the consumer product  118  carries the removable module  110  (e.g., the two parts become an integrated unit). 
     In some embodiments, the shape of the body  111  of the removable module  110  may correspond to a shape of the channel  121 . Furthermore, the length of the body  111 , or the overall length of the removable module  110  may generally correspond to the length of the channel  121 . In some cases, the ends of the removable module  110  may be flush or substantially flush with the surfaces of the housing  120  when fully engaged such as shown in  FIG. 1C . However, the length of the removable module  110  may be less than or greater in length than the channel  121 . Accordingly, the removable module  110  may jut from one or more sides of the channel  121 . 
     The body  111  of the removable module  110  may be configured to engage the housing  120  by sliding within the channel  121  such as shown in  FIG. 1B . Although not shown, a keying feature may be provided to ensure proper alignment between the removable module  110  and the housing  120 . Furthermore, a retention feature such an undercut or flange may be provided to prevent disengagement in a direction that is perpendicular to the length of the channel  121 . In some implementations, the channel  121  of the consumer product  118  may be dimensioned and shaped to provide sliding movement but not lateral movement perpendicular to the sliding direction. In some embodiments, the channel  121  may include a single open end for receiving the body  111 . Alternatively, the channel  121  may include opposing open ends for receiving the body (as shown in  FIGS. 1A-C ). 
     In some embodiments, the removable module  110  may be manufactured from stainless steel, aluminum, plastic, or other such material. Although specific materials are mentioned, the removable module  110 , and/or the components of the attachment system  100 , may be manufactured from various other materials. Likewise, the housing  120  of the consumer product  118  may be made from similar or different materials or combinations of materials. 
     The body  111  of the removable module  110  may include a proximal end  112  and a distal end  113 . In certain embodiments, the proximal end  112  and the distal end  113  of the removable module  110  may each have an arm that extends beyond a width of the body  111  (not shown). In other embodiments, the width of the removable module  110  may be uniform or substantially uniform. In certain embodiments, the removable module  110  may have one or more features, such as a recess  114 , that is configured to receive an accessory, an object, an article and the like. For example, the recess  114  may be configured to receive a pin (not shown) or other connection mechanism that enables a strap or a band, such as, for example, band  422  ( FIG. 4 ), or any other accessory device or component, to be removably attached to the removable module  110 . 
     In embodiments, where the removable module  110  includes one or more arms, an inner side of each of the arms may include a recess. The recess may be used to couple or secure various accessories to the removable module  110 . In another embodiment, the arms of the removable module  110  may include one or more protrusions that extend from the arms of the removable module  110 . In such embodiments, an accessory may have one or more detents that are configured to mate with the protrusions. In yet another embodiment, the protrusions may be magnetized to enable a magnetic connection between the removable module  110  and the accessory. Although not specifically mentioned, other connection mechanisms may be used between the removable module  110  and the accessory. Examples include snaps, hooks and so on. 
     The body  111  of the removable module  110  may also include an opening or aperture (not shown) that extends from a top surface of the body  111  to a bottom side of the body  111 . The opening may be configured to receive and secure a locking mechanism within the opening. As will be explained in greater detail below, the locking mechanism may include a spring-loaded locking mechanism that includes a catch member  116  and a ramp member (not shown). In some embodiments, the opening may partially extend through the body  111  of the removable module  110 . An example locking mechanism is described in more detail below with reference to  FIGS. 7A-B ,  8 A-B and  9 A-C. 
     In some embodiments, the catch member  116  in the removable module  110  may have a top surface that is flush or substantially flush with respect to a top surface of the body  111  when the removable module  110  is not installed or assembled in the channel  121 . In some cases, a lower ramp member (not shown), or the bottom portion of the locking mechanism, may be spring-biased proud with respect to a bottom surface of the body  111 , such that a bottom surface of the ramp member extends or protrudes beyond the bottom surface of the body  111 . In some implementations, as the lower ramp member is forced into the opening of the removable module  110 , an internal spring of the locking mechanism may exert an outward force on the catch member  116 , which may cause the catch member  116  to extend or protrude beyond the top surface of the body  111  and into a corresponding recess or aperture formed in a side wall of the channel  121 . Although the catch member  116  is shown in the figures in a central location, the catch member  116  and the locking mechanism may be located at various positions on the body  111  of the removable module  110 . In addition, a removable module  110  may have multiple locking assemblies placed at various locations along the body  111 . 
     Because the locking mechanism may be spring-biased in a particular manner, such described below with respect to  FIGS. 9A-C , when the ramp member contracts or is pushed into the opening, such as, for example, when the removable module  110  is being received into the channel  121  of a consumer product  118 , the spring mechanisms within the locking mechanism cause the catch member  116  to move from a first position (e.g., the flush or substantially flush position) to a second position if available space within the channel permits the expansion. The second position is a position in which at least a portion of the catch member  116  extends beyond the top surface of the body  111 . However, the catch member  116  will not move from the first position to the second position until the catch member  116  is in proximity to a recess formed within the channel  121  as the recess permits the expansion. 
     Once the catch member  116  is in proximity to the recess within the channel, the locking mechanism expands such that at least a portion of the catch member  116  extends from the body  111  and is received into the recess. Once the catch member is received into the recess, the removable module  110  is locked in place within the channel  121 . In certain embodiments, the recess in the channel  121  is shaped and positioned in such a manner as to enable the catch member  116  to be received directly into the recess when the removable module  110  reaches a determined point within the channel. The determined point within the channel  121  may be when the body  111  of the removable module  110  is centered in the channel  121 . In some cases, the determined point may be a location at which the proximal end  112  and the distal end  113  of the removable module  110  are flush or substantially flush with one or more sidewalls of the housing  120  and/or one or more openings of the channel  121 . 
     To unlock and subsequently remove the removable module  110  from the housing  120 , the housing  120  includes a release mechanism  124  that causes the catch member  116  to be displaced from the recess within the channel when the release mechanism  124  is actuated. Once the catch member  116  has been removed from the recess, the removable module  110  may be slide within, or removed entirely from, the channel  121 . 
     When the removable module  110  is removed from the channel  121 , the spring mechanisms within the locking mechanism cause the ramp member to expand or protrude outwardly from the opening in the body  111  of the removable module  110 . As a result, the ramp member is again spring-biased proud with respect to the bottom surface of the body  111 . The spring mechanisms that cause the ramp member to be biased proud with respect to the body  111  also causes the catch member  116  to be biased flush or substantially flush to the top surface of the body  111 . 
     As discussed above, the housing  120  may include a channel  121  disposed along at least one side. Although a single channel  121  is shown in  FIG. 1A , the housing  120  may have any number of channels  121  disposed on various sides. The channel  121  may include an opening at a distal end of the channel  121  and an opening at a proximal end of the channel such as shown in  FIG. 1A . Although  FIG. 1A  depicts the channel  121  having openings at both a distal end and a proximal end, the channel  121  may have an opening at one end (e.g., the distal end) and be closed or solid at another end (e.g., the proximal end  112 ). In such embodiments, the removable module  110  may travel within the channel  121  until one end of the removable module  110  (e.g., the proximal end  112 ) comes into contact with the closed end of the channel  121 . 
     Although the channel  121  and the button portion of the release mechanism  124  are shown having a particular shape and orientation, each of the above elements may have any shape and orientation. For example, the channel  121  may be rounded or polygonal. Further, the channel  121  may be orientated at any desired position and angle. Additionally, the button portion of the release mechanism  124  may have any desired shape and size and may be positioned at any desired location on the housing  120 . 
       FIG. 1B  illustrates the removable module  110  shown in  FIG. 1A  being partially inserted into the channel  121  of the housing  120  according to one or more embodiments of the present disclosure. As shown in  FIG. 1B , the proximal end  112  of the removable module  110  may be inserted into an opening of the channel  121  of the housing  120  in the direction indicated by arrow  127 . In the present embodiment, the removable module  110  may also be slid into the channel  121  from the opposite end as shown in  FIG. 1B . 
     Although  FIG. 1B  shows the proximal end  112  of the removable module  110  being inserted into the opening of the channel  121  and sliding in the direction of arrow  127 , the distal end  113  of the removable module  110  may be inserted into the channel  121  and may slide within the channel  121  in the direction indicated by arrow  128 . However, regardless of the direction in which the removable module  110  is inserted into the channel  121 , the removable module  110  is configured to slide within the channel  121  in either direction until the locking mechanism, and more specifically the catch member  116  of the locking mechanism, is received into the recess of the channel  121 . 
     In some embodiments, as the removable module  110  is being inserted into the channel  121 , a portion of channel  121  contacts the ramp member of the locking mechanism. Continued movement in the direction indicated by arrow  127  may cause the ramp member to be compressed or withdraw into in the body  111  of the removable module  110  until the locking mechanism enters a fully compressed state (e.g., a state in which the ramp member and the catch member  116  are both contained within the body  111  of the removable module  110  and both the ramp member and catch member  116  are prohibited from expanding). 
       FIG. 1C  illustrates an attachment system  100  in which a removable module  110  is fully engaged with a housing  120  of a consumer product  118  according to embodiments of the present disclosure. In some embodiments, the removable module  110  is fully engaged with the housing  120  when the removable module  110  is centered within the channel  121 . However, in other embodiments, the removable modules  110  may be fully engaged with the housing  120  is a position that is not centered with respect to the channel  121 . 
     As also shown in  FIG. 1C , when the removable module  110  has been fully inserted into the channel  121 , a portion of the removable module  110  may extend in a direction that is perpendicular to the length of the channel  121 . In other embodiments, there may be no lateral extension of the body  111 . In still yet other embodiments, the removable module  110  may be flush or substantially flush with respect to the channel  121  or may be recessed within the channel  121 . Likewise, each of the proximal end and the distal end of the removable module  110  may extend from, be flush or substantially flush, or be recessed from one or more edges or sidewalls of the housing  120  and/or one or more edges or sides of the channel  121 . For example, a sidewall of the proximal end  112  of the removable module  110  and a sidewall of the distal end  113  of the removable module  110  may have a shape that is complimentary to the shape of the sidewall of the housing  120 . Thus, when the removable module  110  is locked in place within the channel  121  of the housing  120 , the sidewalls of the removable module  110  and the sidewalls of the housing  120  are flush and/or smooth with respect to one another. That is, the shape of the sidewall of the removable module  110  may match the shape, or otherwise is coordinated with, the sidewall of the housing  120 . 
     In alternative embodiments, the proximal end  112  and the distal end  113  of the removable module  110  may protrude or extend from the housing  120  when the removable module  110  has been locked within or is otherwise engaged with the channel  121 . Alternatively, the length of the channel  121  and/or the housing  120  may be longer than the length of the removable module  110 . In such instances the proximal end  112  and the distal end  113  of the removable module  110  may be recessed within the channel  121  or the housing  120 . 
     In some embodiments, the locking mechanism may engage with or lock to the housing  120  when the removable module  110  is fully engaged. For example, once the catch member  116  of the locking mechanism is in proximity to or beneath a recess in the channel  121 , one or more spring mechanisms within the locking mechanism cause the catch member  116  of the locking mechanism to expand or protrude into the recess. More specifically, one or more springs in the locking mechanism may cause the catch member  116  to move from a first position, in which the catch member  116  is flush or substantially flush with respect to a top surface of the body  111  of the removable module  110 , to a second position, in which at least a portion of the catch member  116  extends from the top surface of the body  111  and is received into the recess thereby preventing movement of the removable module  110  to the housing  120 . 
     In some embodiments, once the removable modules  110  is fully engaged with the housing  120 , the removable module is retained until released. In some instances, the locking mechanism of the removable module  110  may be released from the recess when a button portion of the release mechanism  124  of housing  120  is actuated. For example, a release mechanism  124 , or portions of a release mechanism  124 , may be located in the recess of the housing  120  above the catch member  116 . When the button portion of the release mechanism  124  is pressed, a plunger of the release mechanism  124  may push or expel the catch member  116  of the locking mechanism out of the recess. Once the catch member  116  is no longer engaged with the recess, the removable module  110  may be once again slid within the channel  121 . 
     In some embodiments, the housing  120  may not include a release mechanism  124 . For example, the locking mechanism may be shaped such that when a force is applied to one end of the removable module  110 , the force causes the removable module  110  to move in the direction of the applied force. As the removable module  110  moves, the locking mechanism contracts and disengaged. The contraction of the locking mechanism may continue as the removable module  110  moves in the direction of the applied force. As a result, the locking mechanism enters a compressed state (e.g., the locking mechanism is contained within the body  111  of the removable module  110 ). When the locking mechanism is in the compressed state, the removable module  110  may slide within the channel  121  such as described earlier. 
     Although not shown, the removable module  110  may have a band, strap or other such accessory, article or object removably coupled thereto. Although a band and a strap are specifically mentioned, the removable module  110  may be coupled to various accessories or devices. For example, the removable module  110  may be used to secure a clip, a lanyard a dock, a case, or a protective cover to the consumer product  118 . In embodiments where the removable module  110  is used to couple a band, strap or other such accessory, article or object to the consumer product  118 , the band or strap may be attached to the removable module  110  using a pin (not shown), a clasp (not shown), a snapping mechanism (not shown) or other type of attachment system. The band or strap may be used to secure the consumer product  118  to a user of the consumer product  118  or to an article of clothing, a stand, a display system, or any suitable item. 
     Although the removable module  110  and the channel  121  are shown having a particular shape in  FIG. 1A-C , the removable module  110  and the channel may vary depending on the embodiment. For example, the body  111  of the removable module  110  may be rounded, squared, triangular and the like such as shown in  FIG. 2A-F . Although a square sidewall and channel are shown in  FIG. 1A-C , the sidewalls of the body  111  of the removable module  110  and the sidewalls of the component or housing  120 , in particular the proximal and distal ends of the channel  121 , may have any desired shape so long as the shapes are complimentary to one another. 
     The particular shape of the channel  121   a - f  and the corresponding shape of the removable module  110   a - f  may include any one of a number of different shapes. For example, shown in  FIG. 2A - FIG. 2F , the sidewalls of the proximal end and the distal end of the removable module  110   a - f , as well as the sidewalls of the channel  121   a - f  may have one or more flanges ( FIG. 2A ), trapezoidal ( FIG. 2B ), curvilinear ( FIG. 2C ), oval ( FIG. 2D ), polygonal ( FIG. 2E ), as well as other desired shapes such as shown in  FIG. 2F . Likewise, the attachment system may be arranged in any desired orientation within the housing  120 . 
     As shown in  FIGS. 2A-F , the channel  121   a - f  may have an undercut that is configured to retain the removable module  110   a - f  within the channel  121   a - f . As shown in  FIGS. 2A-F , the channel  121   a - f  of the consumer product has an opening width  131  at the opening of the channel  121   a - f  and a maximum width  132  within the channel  121   a - f . In some embodiments, the maximum width  132  is greater than the opening width  131  to form an undercut. Similarly, the removable module  110   a - f  may have a has a first portion with a first thickness that is smaller than the opening width  131  of the channel  121   a - f  and a second thickness that is less than the maximum width  132  of the channel  121   a - f  and also greater than the opening width  131 . Thus, due to the undercut formed by the channel, the opening width of the channel  121   a - f  may be configured to limit the movement of the removable module  110   a - f  in a direction perpendicular to opening. 
       FIGS. 3A-C  depict a simplified example of attachment system  310  having a removable module  302  being engaged with a mating feature of a mating component  340 . The mating component  340  may be the housing or body of a device or other type of consumer product. In certain embodiments, the attachment system  310  of  FIG. 3A  may be similar to the attachment system  100  discussed above with respect to  FIG. 1A - FIG. 1C  as well as the other attachment systems, removable modules and the like disclosed herein. 
       FIG. 3A  illustrates a block diagram of an exemplary removable module  302  according to one or more embodiments of the present disclosure. As shown in  FIG. 3A , the removable module  302  may include a locking mechanism having a catch member  304  and a ramp member  306 . In some embodiments, the catch member  304  is coupled to the ramp member  306  by a spring element  308 . In certain embodiments, the catch member may be spring-biased flush or substantially flush with respect to a top surface of the removable module  302  when the locking mechanism is in an expanded state (as shown in  FIG. 3A ). In addition, the ramp member  306  of the locking mechanism may be spring-biased proud with respect to a bottom side of the removable module  302 . 
       FIG. 3B  illustrates a block diagram of a housing or component  340  of a consumer product according to one or more embodiments of the present disclosure. In certain embodiments, the component  340  may be a housing for an electronic device, such as, for example housing  410  such as shown in the figures herein. The component  340  may include a mating feature such as a channel  342  having two ends and an opening extending between the ends. In some embodiments, the channel  342  may have a single opening at one end of the channel  342 . The channel  342  may be configured to receive an attachment system, such as, for example, removable module  302  of  FIG. 3A . 
     As shown in  FIG. 3B , the component  340  may also include a release mechanism  341  disposed relative to the channel  342 . The release mechanism  341  may positioned within or relative to a recess  343  formed in a side wall of the channel  342 . In some embodiments, the actuation of the release mechanism  341  causes the release mechanism  341  to expel the catch member  304  ( FIG. 3A ) from the recess  343  and disengage the removable module  302  from the component  340 . 
       FIG. 3C  illustrates a block diagram of an attachment system  310  having a removable module  302  being inserted into a component or component  340  of a consumer product according to one or more embodiments of the present disclosure. A first end of the removable module  302  may be inserted into an opening of a channel  342  of a component  340 . As the removable module  302  is inserted further into the channel  342  of the component  340 , the ramp member  306  comes into contact with a lower portion of the channel  342  causing the catch member  304  of the removable module  302  compresses. As shown in  FIG. 3C , an upward or inward movement of the ramp member  306  may cause compression of the spring element  308 , which produces an upward or outward force on the catch member  304 . If the movement of the catch member  304  were to be unimpeded, the upward or outward force would cause the catch member  304  to extend or protrude from the upper surface of the removable module  302 . However, as shown in  FIG. 3C , because the catch member  304  is at least partially inserted into the channel  342 , the catch member  304  is prevented from protruding and remains substantially flush with the upper surface of the removable module  302 . Thus, with reference to  FIG. 3C , as the removable module  302  continues to slide or move within the channel  342  of the component  340 , the locking mechanism remains in the compressed state (e.g., both the catch member  304  and the ramp member  306  being contained within the body of the removable module  302 ). The locking mechanism remains in this state until the catch member  304  is in proximity to the recess  343  or other opening within the channel  342 . 
       FIG. 3D  illustrates the removable module  302  fully engaged or inserted into the mating feature of the component  340 , in this case, the channel  342 . As shown in  FIG. 3D , the removable module  302  is positioned such that the catch member  304  is aligned with or proximate to the recess  343 . As also shown in the example of  FIG. 3D , the removable module  302  is centered with respect to the channel  342  and the sides of the removable module  302  are flush or substantially flush with respect to one or more sidewalls of the component  340 . 
     As shown in  FIG. 3D , the catch member  304  is permitted to expand, be received, or otherwise engaged with the recess  343 , which locks the removable module  302  in place within the component  340 . In particular, the catch member  304  of the locking mechanism may move from a first position, in which the catch member  304  is flush or substantially flush with respect to a top surface of the removable module  302 , to a second position in which the catch member  304  of the locking mechanism protrudes from the top surface of the removable module  302  and is received into the recess  343 . The upward or outward movement of the catch member  304  is facilitated by spring element  308 , which maintains the catch member  304  in the second position, as shown in  FIG. 3D . In the present example, the engagement between the catch member  304  and the recess  343  prevents movement of the removable module  302  with respect to the channel  342   
     In an alternative embodiment, the locking mechanism may include a catch member  304  but not a ramp member  306 . In such embodiments, the catch member  304  of the locking mechanism may be biased by a spring or similar element causing the catch member  304  to protrude from a top surface of the body of the removable module  302 . In some embodiments, when the catch member  304  of the locking mechanism comes into contact with the channel  342  of the component  340 , the contact causes the catch member  304  to be withdrawn or depressed into the removable module  302 , causing one or more springs or compressible elements of the locking mechanism to compress. However, when the catch member  304  is in proximity to the recess  343  of the channel  342 , such as described above with respect to  FIG. 3D , the catch member  304  is permitted to expand or otherwise move into the recess  343  thereby locking removable module  302  within the channel. 
     In some embodiments, a release mechanism  341  may be used to disengage or release the removable module  302 . In some cases, in order to unlock the removable module  302 , a release mechanism  341  disposed on the component  340  (e.g., housing) of the consumer product is configured to expel the catch member  304  from the recess  343 . In some implementations, when the release mechanism  341  is actuated, a plunger of the release mechanism  341  causes the catch member  304  of the locking mechanism to move from the second position back to, or substantially back to, the first position. Once the catch member  304  of the locking mechanism has been removed from the recess  343 , the removable module  302  may be moved within, or removed entirely from, the channel  342  of the component  340 . 
       FIG. 3E  illustrates the removable module  302  being removed from a housing or component  340  of a consumer product according to one or more embodiments of the present disclosure. As described above, once the catch member  304  has be expelled or is otherwise removed from the recess  343 , the removable module  302  may slide or move within the channel  342  of the component  340 . For example, as shown in  FIG. 3E , the removable module  302  may be moved in a direction away from the opening  142  and out of opening  143 . In this case, the removable module  302  may be slid out of the channel  342  completely disengaging the removable module  302  from the component  340 . 
     Although actuation of a release mechanism  341  is specifically mentioned, the catch member  304  may be compressed using other methods. However, this alternate design, nor any other alternate design disclosed herein, does not affect the utility of the embodiments disclosed herein. For example, a lateral force may be applied to the removable module  302  when the catch member  304  is within the recess of the channel. As the lateral force is applied to the removable module  302 , the catch member  304  of the locking mechanism may contact the side of the recess  343 . As the removable module  302  continues to move in the direction of the applied force, the side of the recess  343  may cause the catch member  304  of the locking mechanism to further contract until the catch member  304  has moved from the second position back to, or substantially back to, the first position. Once the catch member  304  of the locking mechanism has been removed from the recess, the removable module  302  may move or slide within the channel  342  and may be disengaged or separated from the component  340 .

       FIG. 5A - FIG. 6C  illustrate an exemplary attachment system  405  including a removable module  420  and housing  410  combination in accordance with an embodiment of the present disclosure. The removable module  420  may for example, correspond to the attachment system shown and described with respect to any of the previous figures. Likewise, the housing  410  may correspond to the various housings shown and described above. For example, the removable module  420  and the housing  410  of the attachment system  405  may be similar to the attachment system and housing shown and described with respect to  FIG. 4 . 
     As shown in  FIG. 5A - FIG. 5C , the removable module  420  may be removably coupled to a component or housing  410  of a consumer product. More specifically,  FIG. 5A - FIG. 6C  illustrate the attachment system  405  during various stages of insertion into a component or housing  410  of a consumer product. 
       FIG. 5A  illustrates an exemplary attachment system  405  including a removable module  420  and an exemplary housing  410  or component of a consumer product according to embodiments of the present disclosure. As will be described below, the removable module  420  is configured as an entirely separate unit that may be wholly removed from or integrated with the housing  410  of the consumer product. The removable module  420  may have a rounded and/or tapered body  426  with one or more arms  427  extending from the body  426 . The outer walls of the arms  427  may be smooth and chamfered such as shown. The shape of the arms  427  may vary based on the shape of the channel  412  and the shape of the housing  410 . Further, the arms  427  are configured to be flush or substantially flush with respect to at least a portion of an outer surface  414  of the housing  410  when the removable module  420  has been placed entirely within the housing  410  such as shown in  FIG. 5C . 
     As also shown in  FIG. 5A , the housing  410  may include a release mechanism  430  that is configured to interact with one or more components of the attachment system  405 . For example, the release mechanism  430  is configured to be actuated to release the removable module  420  from the channel  412  of the housing  410  after the removable module  420  has been locked in place within the housing  410 . A more detailed description of an example button is provided below with respect to  FIGS. 11A-B . 
       FIG. 5B  illustrates the removable module  420  being partially inserted into the channel  412  of the housing  410 . As shown in  FIG. 5B , the removable module  420  fits within the channel  412  and is moveable back and forth within the channel  412 . Although not shown in  FIG. 5B , once the body  426  of the removable module  420  has been inserted into the channel  412 , a locking mechanism of the attachment system is compressed such as shown and described with reference to  FIGS. 12A-C . 
     Once the body  426  of the removable module  420  is fully inserted into the channel  412  such as shown in  FIG. 5C , the locking mechanism, or a portion of the locking mechanism, engages with a recess in the channel, which locks the attachment mechanism in place within the channel  412 . Interaction between the locking mechanism and the recess is shown and described in greater detail below with respect to  FIGS. 12A-C  and  13 A-B. When the removable module  420  has been locked within the channel  412 , actuation of the release mechanism  430  on an outer surface  414  of the housing  410  releases the attachment system thereby permitting the removable module  420  to move within the channel  412 . 
       FIG. 6A - FIG. 6C  illustrate various plan views of an attachment system  405  including a removable module  420  and an exemplary housing  410  or component of a consumer product according to embodiments of the present disclosure. In embodiments, the removable module  420  may be similar to the attachment systems shown and described above. As such, the removable module  420  may be inserted into a housing  410  of an electronic device or otherwise coupled to a consumer product. Further, the removable module  420  may be removably connected to a band, a strap, a dock, a stand, a display system and the like. 
     The various components and features of the removable module  420  will be discussed in greater detail below with respect to  FIGS. 7A - FIG. 13B . As such, similar reference numbers may be used across the various figures to show similar components. Additionally, various cross-sectional views represented by cross-section AA and cross-section BB are discussed in greater detail below. Additionally, various cross-sectional views represented by cross-section CC and cross-section DD shown in  FIG. 6A  are discussed in greater detail below. 
       FIG. 6A  illustrates a top view of the removable module  420  not engaged or attached to the housing  410 ,  FIG. 6B  illustrates a top view of the removable module  420  being partially inserted into the channel  412  of the housing  410 , and  FIG. 6C  illustrates a top view of the attachment system being fully inserted into the channel  412  of the housing  410 . As shown in the assembly sequence of  FIGS. 6A-C , the removable module  420  is configured to slidably engage with the channel  412  of the housing  410  to connect the two components. Other components, such as a band or strap, may also be attached to the removable module  420 , which are omitted from these views for clarity. 
     As shown in  FIGS. 6A-C  a catch member of a locking mechanism  440  disposed on the body  426  may also interact with the channel  412 . As will be shown and described below with respect to  FIGS. 12A-C , the catch member of the locking mechanism  440  may be spring-biased flush with respect to the body  426  of the attachment system  405 . As a result, the catch member may be received into the channel  412  with little resistance. However, when the body  426  of the attachment mechanism has been fully received into the channel  412 , the catch member may expand into a recess within the channel  412  such as shown and described below with respect to  FIGS. 12A-C  and  13 A-B. 
     As shown in  FIGS. 6A-C , the removable module  420  may have a profile shape that corresponds to at least a portion of the profile shape of the housing  410 . In particular, as shown in  FIG. 6C , the width of the channel  412  may be substantially equivalent to the width the body  426 . In some embodiments, when the removable module  420  is fully inserted, as shown in  FIG. 6C , at least a portion of the outer surface of the body  426  is flush or substantially flush with an outer surface  414  of the housing  410 . In the present embodiment, the contour of the outer surface of the body  426  corresponds to the contour of the outer surface  414  of the housing. Also, as also shown, the arms  427  of the removable module  420  may extend from the housing  410  in a direction perpendicular to the length of the channel  412 . 
     As shown in  FIGS. 6A-C , the removable module  420  includes arms  427  for coupling the removable module  420  with another component of the accessory. In the present embodiment, an engagement feature  428  is formed in a surface of a respective arm  427 . As shown in  FIGS. 6A-C , the engagement feature  428  may include a recess that is configured to receive a pin, post, or similar protrusion feature of a mating part. In some embodiments, the mating part includes a band strap or other component that is configured to be attached to the removable module  420  using the engagement feature  428 . 
       FIGS. 7A-B  depict an example removable module  420  having a locking mechanism  440 . In particular  FIG. 7A  illustrates a perspective exploded view of a locking mechanism  440  and  FIG. 7B  illustrates a perspective (non-exploded) view of the assembled locking mechanism  440  of  FIG. 7A . The locking mechanism  440  of  FIGS. 7A-B  may correspond to the locking mechanism referenced in embodiments described above with respect to previous figures. While the terms “upper,” “upward,” “lower,” and “downward” are used with respect to surfaces and positions of elements in the following embodiments, the terms are relative in nature and are not intended to require an absolute orientation or position. 
     In general, the removable module  420  of  FIGS. 7A-B  is configured to slidably engage with a mating feature of an consumer product or component of a consumer product. The consumer product may include, for example, an electronic device, wearable electronic device, wearable device, and the like. In some embodiments, the mating feature of the consumer product forms a channel or opening for receiving the removable module  420 , as described above with respect to  FIGS. 5A-C . 
     The locking mechanism  440  of  FIGS. 7A-B  may be configured to engage with a recess, pocket, or aperture formed into or through the mating feature of the consumer product. When engaged with the recess, pocket, or aperture of the consumer product, the locking mechanism  440  may retain the removable module  420  within the mating feature. As discussed in more detail below with respect to  FIGS. 13A-B , the locking mechanism  440  may also be configured to be disengaged using a release mechanism integrated with or installed in the consumer product. 
     As shown in  FIG. 7A , the locking mechanism  440  is a spring-loaded mechanism that is configured to protrude or extend a catch member  442  with respect to an upper surface  462  of the removable module  420 . In the present example, the locking mechanism  440  is configured to be installed or disposed with respect to aperture  424  formed in the body of the removable module  420 . The locking mechanism  440  includes a catch member  442  that is disposed or positioned within the aperture  424  and oriented toward the upper surface  462  of the removable module  420 . The locking mechanism  440  also includes a ramp member  448  that is disposed or positioned within the aperture  242  and is oriented toward a lower surface  464  of the removable module  420 . 
     In the embodiment depicted in  FIG. 7A , two spring bars  444  are positioned within the aperture  242  spanning across the width of the aperture  424 . As shown in  FIGS. 7A-B , the spring bars  444  are generally positioned between the catch member  442  and the ramp member  448 . In the present example, the spring bars  444  are arranged substantially perpendicular to the long axis or length of the removable module  420 . In other embodiments, the spring bars  444  may be positioned in a different orientation with respect to the length of the removable module  420 . 
     As shown in  FIGS. 7A-B , a first spring  446  is positioned or coupled between each spring bar  444  and the ramp member  448 . The first spring  446  generally biases the ramp member  448  away from the respective spring bar  444  and also in the direction of the lower surface  464 . In the present embodiment, the first spring  446  may include a coil-type compression spring formed form a material such as steel, spring steel, stainless steel, music wire, plastic, bronze, and the like. Other types of springs may also be used including, for example, elastomeric members, foam members, spring clips, torsion springs, or any other component configured to provide a biasing force. 
     As shown in  FIGS. 7A-B , a second spring  447  is positioned or coupled between the ramp member  448  and the catch member  442 . The second spring  447  generally biases the catch member  442  away from the ramp member  448  and also in the direction of the upper surface  462 . In the present embodiment, only a single second spring  447  is used. However, in other embodiments, more than one spring may be used to bias the catch member  442  and the ramp member  448  away from each other. In the present embodiment, the first spring  447  may also include a coil-type compression spring formed form a material such as steel, spring steel, stainless steel, music wire, plastic, bronze, and the like. Other types of springs may also be used including, for example, elastomeric members, foam members, spring clips, torsion springs, or any other component configured to provide a biasing force. 
     In the present example, the spring bars  444  are configured to facilitate the installation of the locking mechanism  440  within the aperture  424  of the removable module  420 . In particular, the spring bars  444  are configured to be at least partially collapsible such that the spring bars  444  may be inserted into the aperture  424  in a partially collapsed or compressed state. Once inserted, the spring bars  444  may expand or extend into respective mating features formed into the sidewall of the aperture  424 . As described in more detail below with respect to  FIGS. 10A-B , the mating features may include one or more recesses or pockets formed into the wall of the aperture  424 . In the present example, two spring bars  444  are used to retain or capture the locking mechanism  440 . However, in other embodiments, a single spring bar may be used or more than two spring bars may be used to retain or capture the locking mechanism  440  within the removable module  420 . 
     The spring bars  444  may include a spring-loaded mechanism that is configured to partially collapse when loaded and return to an extended position when unloaded. In some embodiments, the spring bar  444  includes a barrel portion and two spring-loaded protrusions that extend out from each end of the barrel portion. The spring-loaded protrusions may be configured to engage a recess feature formed into the wall of the aperture  424 . In some embodiments, the spring bar  444  includes only a single spring-loaded protrusion that extends out from one end of the barrel portion. In the present embodiment, the spring bars  444  are generally formed as a straight cylindrical shape. However, in other embodiments, the spring bars  444  may be formed from a curved cylindrical shape, bent cylindrical shape, or be formed from a variety of other types of shapes. 
       FIGS. 8A-B  depict cross-sectional views of the locking mechanism  440  of  FIGS. 7A-B . The configurations depicted in  FIGS. 8A-B  are illustrative in nature and the specific geometry or location of the various feature may vary without departing from the concepts described herein. In particular,  FIGS. 8A-B  depict an example mechanism that uses spring bars  444  to capture or secure the locking mechanism  440  within the aperture  424  and features that provide an engagement between the catch member  442  and the ramp member  448 . 
       FIG. 8A  illustrates a cross-sectional view of the locking mechanism of  FIG. 7A  taken along section  8 A- 8 A. As shown in  FIG. 8A , the first springs  446  are coupled between the respective spring bars  444  and the ramp member  448 . As discussed above, the first springs  446  bias the ramp member  448  away from the spring bars  444 . In the present example, the ramp member  448  protrudes from the lower surface  464  due to the biasing force provided by the first springs  446 . 
     As shown in  FIG. 8A , the second spring  447  biases the catch member  442  away from the ramp member  448 . In the present example, the catch member  442  remains substantially flush with the upper surface  462  due to the biasing force provided by the second spring  447 . Additionally, the catch member  442  is mechanically engaged to the ramp member  448  to limit the upward or outward movement of the catch member  442 . In the present example, a catch-retaining feature  454  mechanically engages with a ramp-retaining feature  456  to prevent the upward or outward movement of the catch member  442 . In particular, the catch-retaining feature  454  includes a protrusion that is configured to engage with a mating protrusion formed by the ramp-retaining feature  456 . While  FIG. 8A  depicts the retaining features  454 ,  456  as being integrally formed elements of the respective parts, in alternative embodiments, the retaining features  454 ,  456  may be formed from separate components that are attached to the respective members. 
     As shown in  FIG. 8B , the locking mechanism  440  is retained or captured within the aperture  424  by the spring bars  444 . In particular, the spring bars  444  are configured to engage a recess  466  formed in the wall of the aperture  424 . In some embodiments, the recess  466  is formed in a middle or central portion of the aperture  424  to hold the spring bars  444  across the width of the middle or central portion of the aperture  424 . In the present example, the spring bars  444  are used to couple to a pair of first springs  446  that exert a downward or outward biasing force on the ramp member  448  toward the lower surface  464 . Thus, the spring bars  444  limit the upward or inward movement of the ramp member  448 . 
     As shown in  FIG. 8B , the ramp member  448  is retained within the aperture  424  by retaining feature  425 . In the present embodiment, the retaining feature  425  is a shoulder or shelf projecting from the wall of the aperture  424 . In some embodiments, the retaining feature may be formed from a protrusion, boss, or other type of feature that extends inward from the wall of the aperture  424 . In some embodiments, the retaining feature  425  is formed from a separate part that is installed or attached to the removable module  420 . For example, the retaining feature  425  may be formed by a collar or snap ring that is fastened or attached to the removable module  420 . 
     In some embodiments, the spring bars  444  may also partially guide one or more components of the locking mechanism  440 . For example, as shown in  FIG. 8A , the spring bars  444  may slidably engage with a corresponding slot or opening formed in the ramp member  448 . In the present example, the spring bars  444  may slidably engage with the walls of the slot or openings to guide the ramp member  448  as it moves up and down within the aperture  424 . In some embodiments, the catch member  442  may also include a slot or opening for slidably engaging one or both of the spring bars  444 . 
       FIGS. 9A-B  illustrates cross-sectional views of the body of a removable module  420  and spring bars  444 . As previously discussed, the spring bars  444  may be configured to be installed within the aperture  424  formed in the body of the removable module  420 . As shown in  FIGS. 9A-B , each spring bar  444  engages a respective recess  466  formed in the wall of the aperture  424 . In some embodiments, the recess  466  includes an undercut or shelf that prevents the upward (or downward) movement of the spring bar  444  along the length of the aperture  424 . As shown in  FIGS. 9A-B , the recess  466  may be elongated laterally with respect to the axis of the aperture  424 , which may facilitate installation of the spring bars  444  and the locking mechanism. In particular, the elongated recess  466  may allow for some variation in the tolerance in the placement of the spring bars  444  within the locking mechanism in a direction that is lateral to the axis of the aperture  242 . In some embodiments, the recesses  466  may also include an edge break or lead-in feature that facilitates installation of the spring bars  444 . 
     As also shown in  FIGS. 9A-B , a retaining feature  425  is formed within a lower portion of the aperture  424 . A cross-sectional view of the retaining feature  425  is also depicted in  FIG. 8B , discussed above. In the present example, the retaining feature  425  includes a shelf that protrudes inward toward the center of the aperture  424 . As shown in  FIGS. 9A-B , the retaining feature  425  may be formed along one edge of the aperture  424 . In other embodiments, the retaining feature  425  may not extend fully along the edge of the aperture  424 . In other embodiments, the retaining feature  425  may extend all the way around the perimeter of the aperture  424 . 
     The locking mechanism  440  described above with respect to  FIGS. 7A-9B  may be installed or assembled into the removable module  420  by positioning the components of the locking mechanism  440  relative to each other, compressing the spring bars  444 , and inserting the locking mechanism  440  into the aperture  424  of the removable module  420 . For example, the spring bars  444  may be positioned with respect to the ramp member  448  by placing the two components into a fixture or a tooling jig. The first spring  446  may also be disposed between the ramp member  448  and each of the spring bars  444 . As part of the installation or assembly, the catch member  442  may be positioned with respect to the ramp member  448 . In some implementation, the respective engagement features  454 ,  456  of the catch member  442  and the ramp member  448 , respectively, are engaged or interlocked with each other. The second spring  447  may be disposed between the catch member  442  and the ramp member  448 . To install or assemble the locking mechanism  440 , both spring bars  444  may be compressed using a clamp or other installation tool. While the spring bars  444  are compressed, the locking mechanism  440 , including the ramp member  448 , catch member  442 , and the spring bars  444 , may be inserted into the aperture  424  formed within the removable module. When fully inserted, each of the spring bars  444  may engage with a respective recess  466  formed in a wall of the aperture  424 . 
     In some embodiments, the locking mechanism  440  may be configured to be placed in a variety of states, depending on the forces exerted on the mechanism while being inserted into a mating feature of a component.  FIGS. 10A-C  illustrate front cross-sectional view of a locking mechanism in various states as it is being engaged with a mating feature of a consumer product. 
       FIG. 10A  illustrates an uncompressed state of the locking mechanism  440  of an example removable module  420 .  FIG. 10A  may correspond to the state of the locking mechanism  440  when the removable module  420  is not engaged with a mating feature (e.g., a channel) of a mating component. As shown in  FIG. 10A , a portion of the ramp member  448  protrudes beyond the lower surface  464  of the removable module  420 . In particular, the ramp member  448  includes curved outer surface having a middle portion that protrudes beyond the lower surface  464  and side portions that are flush or nearly flush with the lower surface  464 . The curved outer surface of the ramp member  448  may facilitate the installation of the removable module  420  by reducing or eliminating potential catch points as the body of the removable module is inserted into a mating feature, such as a channel. 
     As shown in  FIG. 10A , in the uncompressed state of the locking mechanism  440 , the catch member  442  is substantially flush or below flush with respect to the upper surface  462 . As discussed above with respect to  FIGS. 8A-B , the catch-retaining features and the ramp-retaining features prevent the upward or outward movement of the catch member  442 , which may maintain the flush or below flush position when in an uncompressed state, as depicted in  FIG. 10A . As shown in  FIG. 10A , the catch member  442  may also include a chamfer or edge break around the perimeter of the upper surface of the catch member  442 , which may reduce or eliminate potential catch points as the body of the removable module is inserted into a mating feature, such as a channel. 
       FIG. 10B  illustrates an partially compressed state of the locking mechanism  440  of an example removable module  420 .  FIG. 10B  may correspond to the state of the locking mechanism  440  when the removable module  420  is partially engaged with a mating feature (e.g., a channel) of a mating component. As shown in  FIG. 10B , the ramp member  448  is flush or below flush with respect to the lower surface  464 . As also shown in  FIG. 10B , the catch member  442  is flush or below flush with respect to the upper surface  462 . 
       FIG. 10C  illustrates an engaged state of the locking mechanism  440  of an example removable module  420 .  FIG. 10C  may correspond to the state of the locking mechanism  440  when the removable module  420  is fully engaged with or fully inserted into a mating feature (e.g., a channel) of a mating component. As shown in  FIG. 10C , the ramp member  448  remains flush or below flush with respect to the lower surface  464 . As also shown in  FIG. 10C , a portion of the catch member  442  extends beyond the upper surface  462  of the removable module  420 . As described in more detail with respect to  FIGS. 12A-C  and  13 A, the extended catch member  442  may engage a corresponding feature, such as a recess or pocket formed in the wall of the mating feature or channel of the mating component. The engagement provided by the catch member  442  may prevent removable module  420  from sliding within the mating feature thereby retaining or locking the removable module  420  to the mating component. 
     As previously discussed, an example attachment system may include a release mechanism for disengaging a locking mechanism of removable module.  FIGS. 11A-B  depict an example release mechanism installed in a housing of a consumer product. The release mechanism may be configured to disengages or release a locking mechanism of a removable module, in accordance with embodiments described herein. In particular,  FIG. 11A  illustrates an exploded view of an example release mechanism and  FIG. 11B  illustrates an assembled release mechanism. 
     As shown in  FIGS. 11A-B , the release mechanism  430  includes a button member  432  at least partially disposed within an aperture  416  formed in the body of the housing  410 . In the present embodiment, the aperture  416  is aligned with a recess  417  formed into the wall of the channel  412  and extends through to an upper surface of the housing  410 . In the present example, the aperture  416  has a length that is greater than the length of the recess  417 . However, in other embodiments, the length (or width) of the aperture  416  may be less than the length (or width) of the recess  417 . 
     On the present embodiment, the button member  432  is configured to move up and down within the aperture  416  formed in the surface of the housing  410 . The button member  432  may be at least partially retained by one or more spring bars  434  that are positioned within the aperture  416 . The spring bars  434  may be received by an aperture feature formed in the button member  432  otherwise referred to an button aperture. In the present example, the spring bars  434  are received in respective elongated or slotted holes formed in the button member  432 , as shown in  FIG. 11A . In some embodiments, the feature of the button member  432  that engages the spring bars  434  is not an aperture and may be formed by one or more protrusions or other features formed into the button member  432 . In some embodiments, the spring bars  434  limit the motion of the button member  432  in at least one direction. For example, the spring bars  434  may limit the upward or outward motion of the button member  432  to prevent the button member  432  from being completely removed from the aperture  416 . 
     In the present example, a pair of spring bars  434  span across the width of the aperture  416  and are retained by respective recesses or pockets formed in the wall of the aperture  416 . The configuration of the recesses or pockets in the aperture  416  may be similar to the recesses  466  described above with respect to  FIGS. 9A-B . In particular, the recesses or pockets may be elongated along a direction perpendicular to an axis of the aperture  416  to facilitate installation of the spring bars by allowing for variations in the (horizontal) position of the spring bars  434  with respect to the axis of the aperture  416 . 
     In the present example, two spring bars  434  are used to retain or capture the button member  432 . However, in other embodiments, a single spring bar may be used or more than two spring bars may be used to retain or capture the button member  432  within the aperture  416 . In some embodiments, the one or more spring bars  434  slidably engage a corresponding feature(s) formed into the button member  432  and help to guide the button member  432  as it moves up and down within the aperture  416 . 
     Similar to the example described above with respect to  FIGS. 7A-B , the spring bars  434  may include a spring-loaded mechanism that is configured to partially collapse when loaded and return to an extended position when unloaded. In some embodiments, the spring bar  434  includes a barrel portion and one or more spring-loaded protrusions that extend out from the end(s) of the barrel portion. In the present embodiment, the spring bars  434  are generally formed as a straight cylindrical shape. However, in other embodiments, the spring bars  434  may be formed from a curved cylindrical shape, bent cylindrical shape, or be formed from a variety of other types of shapes. 
     As shown in  FIG. 11A , a pair of springs  438  are positioned between the button member  432  and a feature formed into the body of the housing  410 . The springs  438  bias the button member  432  outward or upward away from the channel  412 . In the embodiment of  FIGS. 11A-B , each spring  438  is coupled between a lower surface of the button member  432  and a shoulder feature formed between the aperture  416  and the recess  417 . In an alternative embodiment, the springs  438  may be disposed in a separate hole or recess that is formed into the body of the housing  410 . In yet another alternative embodiment, one or more springs may be disposed between the button member  432  and another component coupled to the body of the housing  410 . In some embodiments, the spring  438  may include a coil-type compression spring formed form a material such as steel, spring steel, stainless steel, music wire, plastic, bronze, and the like. Other types of springs may also be used including, for example, elastomeric members, foam members, spring clips, torsion springs, or any other component configured to provide a biasing force. 
     In some embodiments, there is no spring included in the release mechanism  430 . That is, an internal spring is not used to bias the button member  432  outward or away from the channel  412 . In such embodiments, the spring-loaded locking mechanism (e.g.,  440  of  FIGS. 7A-B ) may provide a biasing force to the button member  432 . 
     As shown in  FIG. 11A , the button member  432  includes a actuation portion  435  and a plunger portion  436 . The actuation portion  435  may include an upper part of the button member  432  that is configured to be actuated by the press of a finger. In some embodiments, the actuation portion  435  is sized to receive a finger press or actuation. In some embodiments, the actuation portion  435  is sized to receive or be actuated by a pointed object, such as a pen or pointed tool. In some embodiments, the actuation portion  435  protrudes slightly above the surface of the body of the housing  410 . In some embodiments, the actuation portion  435  is flush or slightly below flush with respect to the body of the housing  410 . 
     As shown in  FIG. 11A , the button member  432  may also include a plunger portion  436  that is configured to enter the recess  417  and engage a catch member of a locking mechanism (e.g., item  442  of  FIGS. 7A-B ). In some embodiments, the plunger portion  436  may be sized to substantially fill the recess  417 . In other embodiments, the plunger portion  436  may be significantly smaller than the recess  417 . For example, in some embodiments, the plunger portion  436  may be formed from a cylindrical rod section or multiple cylindrical rod sections. 
       FIGS. 12A-C  depict the relative movement of the locking mechanism  440  with respect to features formed in a housing  410  and the operation of the release mechanism  430 . The sequence depicted in  FIGS. 12A-C  may be applicable to the embodiments described above, particularly  FIGS. 4-11B . The cross-sectional views depicted in  FIGS. 12A-C  may correspond to section A-A of  FIGS. 6A-C . 
       FIG. 12A  illustrates a front cross-section view of a removable module  420  being inserted into a channel  412  of a housing  410  of a consumer product. The configuration depicted in  FIG. 12A  may correspond to an uncompressed state or condition of the locking mechanism. In an uncompressed state or condition, the catch member  442  may be substantially flush or below flush with respect to the upper surface  462 . As shown in  FIG. 12A , a portion of the ramp member  448  protrudes beyond the lower surface  464  of the removable module  420 . In particular, the ramp member  448  includes curved outer surface having a middle portion that protrudes beyond the lower surface  464  and side portions that are flush or nearly flush with the lower surface  464 . The curved outer surface of the ramp member  448  may facilitate the installation of the removable module  420  by reducing or eliminating potential catch points as the body of the removable module is inserted into a mating feature, such as a channel. 
     As shown in  FIG. 12A , the ramp member  448  is in contact with an edge of the channel  412  formed in the housing  410 . In the present embodiment, as the removable module  420  is inserted further into the channel  412 , the ramp member  448  will be compressed or withdrawn into the aperture of the removable module  420  due to the contact with the channel  412 . As shown in  FIG. 12A , the curved shape of the lower surface of the ramp member  448  facilitates a smooth compression of the locking mechanism as the removable module  420  is being inserted. 
     Also, as shown in  FIG. 12A , the catch member  442  is already engaged within the channel  412  as the ramp member  448  contacts the edge of the channel  412 . Thus, as the ramp member  448  is compressed or withdrawn into the removable module  420 , the catch member  442  will not protrude significantly beyond the upper surface  462  of the removable module  420  because it has already been at least partially inserted or engaged with the channel  412 . As shown in  FIG. 12A , an upper edge of the channel  412  may extend slightly beyond the lower edge of the channel  412  to engage the catch member  442  while it is still flush or nearly flush with respect to the upper surface  462 . 
       FIG. 12B  illustrates a front cross-section view of the attachment system partially inserted into the channel of the housing of the consumer product. The configuration depicted in  FIG. 12B  may correspond to the state or condition of the locking mechanism being compressed. As shown in  FIG. 12B , the removable module  420  has been inserted into the channel  412  such that both the catch member  442  and the ramp member  448  are held within the channel  412 . As shown in  FIG. 12B  the ramp member  448  is flush or below flush with respect to the lower surface  464 . As also shown in  FIG. 10B , the catch member  442  is flush or below flush with respect to the upper surface  462 . The locking mechanism may remain in this compressed state as the removable module  420  is being inserted until the catch member  442  is aligned with a recess, as shown in  FIG. 12C . 
       FIG. 12C  illustrates a front cross-section view of the locking mechanism of the attachment system fully inserted into the channel of the housing in which a catch member of the locking mechanism is engaged with a recess formed in the channel of the housing of the consumer product. As shown in  FIG. 12C , the ramp member  448  remains flush or below flush with respect to the lower surface  464 . Also, as shown in  FIG. 12C , a portion of the catch member  442  extends beyond the upper surface  462  of the removable module  420  and engages recess  417  formed into the housing  410 . The engagement between the catch member  442  and the recess  417  may prevent removable module  420  from sliding within the channel  412  thereby retaining or locking the removable module  420  to the housing  410 . In the present embodiment, the internal springs (e.g., second spring  447  of  FIG. 7A ) biases the catch member  442  toward the recess  417  thereby maintaining the engagement between the catch member  442  and the housing  410 . 
     As shown in  FIG. 12C , the release mechanism  430  is also positioned above the recess  417  and is depicted in an un-actuated or uncompressed state. When the release mechanism  430  is in an un-actuated or uncompressed state, the catch member  442  may remain at least partially inserted in the recess  417  maintaining the engagement between the locking mechanism of the removable module  420  with respect to the housing  410 . 
       FIGS. 13A-B  depict an example actuation of the release mechanism  430  in accordance with some embodiments. The cross-sectional views of  FIGS. 13A-B  correspond to section B-B depicted on  FIG. 6C . In particular,  FIG. 13A  illustrates a side cross-sectional view of a locking mechanism  440  engaged with a housing  410  of a consumer product. In the state or configuration depicted in  FIG. 13A , the catch member  442  is at least partially disposed within the recess formed within the housing  410 . Also as shown in  FIG. 13A , the release mechanism  430  is in an uncompressed or un-actuated state similar to the configuration depicted in the front cross-sectional view of  FIG. 12C , discussed above. In the present embodiment, the plunger portion  436  of the button member is touching or nearly touching the top of the catch member  442 . In some embodiments, the catch member  442  exerts an upward force on the plunger portion  436  of the button member. 
       FIG. 13B  illustrates actuation of a release mechanism being actuated or compressed. As indicated by the arrow in  FIG. 13B , a downward or inward actuation force may be applied to the actuation portion  435  of the release mechanism  430 . The actuation force may cause the spring of the release mechanism  430  to compress and cause the button member to move downward or inward toward the channel formed in the housing  410 . As shown in  FIG. 13B , the downward or inward movement of the button member causes the plunger portion  436  compress the catch member  442  back into the aperture formed in the removable module. In some embodiments, the actuation of the release mechanism  430  causes the catch member  442  to be flush or below flush with respect to the upper surface of the removable module. In some implementations, the catch member  442  may still slightly protrude above the upper surface of the removable module when the release mechanism  430  is actuated. In the present embodiment, the actuation force must be great enough to overcome both the spring elements of the release mechanism (if any) and the spring elements of the locking mechanism used to bias the catch member  442  toward the recess formed in the housing  410 . 
     In some implementations, the actuation of the release mechanism  430 , as depicted in  FIG. 13B  allows the movement of the removable module within the channel of the housing  410 . In particular, the release mechanism  430  may be actuated while simultaneously moving the removable module within the channel to prevent re-engagement between the catch member  442  and the recess in the housing  410 . Once the catch member  442  and the recess are no longer aligned, the release mechanism  430  may be un-actuated or uncompressed and the removable module may be continued to be slideably disengaged from the housing  410 . 
       FIG. 14  illustrates a process  1400  of inserting and securing a removable module into a channel of a housing or component of a consumer product according to one or more embodiments of the present disclosure. In some embodiments, the process  1400  may be used to insert various attachment systems into various channels, components, apertures, and the like such as described herein. For example, process  1400  may be used to insert the removable module  110 ,  420  into a channel  121 ,  412  of a housing  120 ,  410  shown and described with respect to  FIGS. 1A-C  and  4 - 13 B, respectively. Although specific attachment systems and channels are described, the process  1400 , or portions thereof, may be used to insert any of the attachment systems described herein into any of the channels of the various devices described herein. 
     In operation  1410 , a removable module may be inserted into the channel of a housing or component. In some embodiments, the removable module has a body with a profile shape that is extruded or extended along a length of the body. Similarly, the housing or component may have a corresponding opening or feature having a similar profile shape that is extended along a length or direction. With regard to operation, the removable module may be inserted by sliding the body of the removable module into the opening in the housing along a direction that is substantially aligned with both the length of the body and the length of the opening. 
     As previously described, the removable module may include a spring-loaded locking mechanism. In some embodiments, a first portion of the locking mechanism may be spring-biased flush with respect to the attachment system. The first portion of the locking mechanism may correspond to the catch member described above with respect to the previous figures. A second portion of the locking mechanism may be spring-biased proud with respect the removable module. The second portion of the locking mechanism may correspond to the ramp member described above with respect to the previous figures. The locking mechanism may also include a first set of spring elements or mechanisms that cause the first portion of the locking mechanism and the second portion of the locking mechanism to be biased away from each other. In addition, a second set of spring elements or mechanisms may cause the second portion to be biased proud with respect to a surface of the removable module. The second set of spring elements or mechanisms may also cause the first portion of the locking mechanism to be biased flush with respect to the removable module. 
     In operation  1420 , a force is applied to at least one side of the removable module. As the force is applied to the removable module, the removable module slides within the channel in generally the direction of the side force. In some embodiments, the first portion of the locking mechanism has a length that is substantially equal to, or slightly greater than, a length of the second portion of the locking mechanism. As such, as the removable module slides further into the housing, the first portion of the locking mechanism enters the channel prior to the second portion of the locking mechanism coming into contact with an outer edge of the channel. Alternatively, the channel may have a first edge that protrudes beyond a second edge resulting in the first portion of the locking mechanism engaging the first edge before the second portion of the locking mechanism engages the second edge. In either case, the channel may to keep the first portion of the locking mechanism in a compressed state even when the second portion of the locking mechanism is begins to enter a compressed state due to contact with the channel such as described above. 
     In operation  1430 , the second portion of the locking mechanism of the removable module comes into contact with the channel. In some embodiments, when the second portion of the locking mechanism comes into contact with the channel and force is continually applied on the removable module, the channel causes the second portion of the locking mechanism to compress or withdraw into the removable module. 
     In some embodiments, as the removable module is further inserted into the channel, the first set of spring elements or mechanisms and a second set of spring elements or mechanisms enable the second portion of the locking mechanism to compress until the second portion of the locking mechanism is contained within the removable module or at least until the second portion of the locking mechanism is contained within the channel. Although the first and the second set of spring elements or mechanisms are compressed, and although the first set of spring elements or mechanisms cause the first portion of the locking mechanism to be biased away from the second portion of the locking mechanism, the first portion of the locking mechanism is contained within the channel which prohibits the first portion of the locking mechanism from expanding. Therefore, the locking mechanism may remain in a compressed state. In some embodiments, the locking mechanism remains in the compressed state as the removable module continues to slide within the channel. However, when the locking mechanism is in proximity to, or beneath a recess contained in the channel, the flow of process  1400  may proceed to operation  1440  and the locking mechanism may expand or extend into a recess of the housing. 
     In operation  1440 , the first portion of the locking mechanism aligns with and engages the recess in the channel. In some embodiments, the first set of spring elements mechanisms of the locking mechanism expand. The expansion of the first set of spring elements or mechanisms causes the first portion to move in a direction toward the recess. When the first portion of the locking mechanism is in the recess, the removable module may be locked in place. Although the first portion of the locking mechanism is in an expanded state (e.g., a state in which a portion of the first portion of the locking mechanism extends beyond the removable module), one or more embodiments provide that the second portion of the locking mechanism remains in a contracted or withdrawn state due to continued contact with the channel of the housing. 
     In some embodiments, the removable module may be retained or locked with respect to the housing until the first portion is disengaged or released with respect to the recess in the channel of the housing. In some embodiments, the resulting engagement of the removable module with respect to the housing results in a secure connection between the housing of a device and an accessory such as a band, strap, or other attachment accessory. 
       FIG. 15  illustrates an example process  1500  of removing an removable module from a housing or component of a consumer product according to one or more embodiments of the present disclosure. In some embodiments, the process  1500  may be used to remove various removable modules from various channels such as described herein. For example, process  1500  may be used to disengage a locking mechanism of the removable module  110 ,  420  from the channel  121 ,  412  of a housing  120 ,  410  shown and described with respect to  FIGS. 1A-C  and  4 - 13 B, respectively. Although specific removable modules and channels are described, the process  1500 , or portions thereof, may be used to remove any of the removable modules described herein from any of the channels, components, apertures, housings, and the like described herein. 
     In operation  1510 , a release mechanism on a housing of a consumer product is actuated. The release mechanism may be actuated, for example, by applying a force to an actuation portion or first portion of the release mechanism using an object, such as a finger or tool. In some embodiments, when a first portion of the release mechanism is actuated, a spring mechanism in the release mechanism compresses and enables the first portion of the release mechanism to move within an opening in the housing. In some embodiments, the first portion of the release mechanism corresponds to the actuation portion described with respect to the previous figures. The actuation of the first portion may also cause a second portion of the release mechanism to move from a first position in a recess of a channel in the housing to a second position within the recess of the channel. In some embodiments, the second portion of the release mechanism corresponds to the plunger portion described above with respect to the previous figures. 
     In operation  1520 , the movement of the release mechanism may cause the second portion of the release mechanism to expel a first portion of a locking mechanism of an removable module from the recess. As previously discussed with respect to  FIGS. 13A-B , the second portion of the release mechanism may depress the first portion of the locking mechanism to be flush or nearly flush with a surface of the removable module, thereby disengaging the locking mechanism from the housing. 
     Once the first portion of the locking mechanism has been expelled from the recess, in operation  1530 , a force may be applied to the removable module to move the removable module within the channel. For example, when the first portion of the release mechanism is actuated, spring elements or mechanisms in the release mechanism may compress and enable the first portion to move within the housing. Actuation of the first portion of the release mechanism may also cause the second portion of the release mechanism to move from a first position in the recess to a second position within the recess. As the second portion of the release mechanism moves from the first position to the second position, the second portion of the release mechanism may cause a spring element or mechanism in the locking mechanism to compress. The compression may result in the first portion of the locking mechanism to be removed from the recess. Once the first portion of the locking mechanism has been removed from the recess, the removable module may move within the channel in a direction of applied force. 
     In operation  1540 , the removable module may be removed from the channel and a second portion of the locking mechanism of the removable module may expand. In some implementations, when the second portion of the locking mechanism is removed from the channel of the housing of the consumer product, the second spring elements or mechanism may cause the second portion of the locking mechanism to be biased proud with respect to the removable module while causing the first portion of the locking mechanism to be biased flush or substantially flush with respect to the removable module. 
     In some embodiments, the result of process  1500  is that band, strap, or other attachment accessory is detached from the housing of a device. In some embodiments, process  1500  may be used to detach a first type of band, strap, or other attachment accessory and process  1400  can be used to attach a different, second type of band, strap, or other attachment accessory. In some embodiments, the attachment systems and methods described herein may be used to create an interchangeable system of components and accessories that can be attached to a consumer product. The interchangeable components or accessories may alter the functionality and/or appearance of the consumer product and thereby expand the applicability or use of a particular consumer product.
