Patent Description:
Users attempt to personalize their devices by application of adhesives, external covers, sleeves, printing, or other modifications to the device appearance. These efforts usually result in a device that is appropriate for one type of setting, but not others, which can be frustrating to users and discourage the otherwise desired personalization of their device. For example, purchasing and applying stickers on a device can cause other logistical issues when the stickers need to be removed. Similarly, when a user desires to effect a change in external appearance of their device for whatever reason (e.g., change in environment, outfit, etc.), the user may need to spend time removing the previous personalization items, typically leaving behind residue that needs to be cleaned, as well as destroying the value of the personalization items as they are extracted from the surface of the device. Often when trying to alter the device's appearance, scratches or other damage to the device can occur. This can result in various levels of inconvenience and annoyance, and can deter a user from modifying the appearance of their laptop to gain a desired aesthetic.

Although some mechanisms for altering the appearance of a computing device exist, most such mechanisms tend to be ineffective and inconvenient. For example, these mechanisms can be bulky, expensive, and difficult to implement. Such mechanisms can be also be obvious, and can diminish the intended aesthetics, and in some cases even the function, of the resultant device's external appearance. Furthermore, once a user makes a modification, or purchases a device with a particular appearance, further alterations can be complicated and frustrating. Due to these and other inconveniences, an end-user may ultimately forego changing the device cover. Thus, there remain significant areas for new and improved ideas for offering device appearance personalization options in a way that meets the needs of today's users as they transition between one activity and the next with the awareness that their devices provide an important extension to their own aesthetic ensemble and self-expression. Reference is made to <CIT>, <CIT>, and <CIT> which have been cited as relating to the state of the art. Each document provides different alternative arrangements for fixing components.

The scope of the invention is in accordance with the claims. Accordingly, there is provided an interchangeable housing component for a portable computing device in accordance with claims <NUM> and a kit of parts in accordance with claim <NUM>.

An interchangeable housing component for a portable computing device, in accordance with a first aspect of this disclosure, has a body portion including an upper surface, an opposite-facing lower surface, and a forward edge, a rearward edge, a first side edge, and a second side edge. The interchangeable housing component also includes a first sidewall extending outward from the first side edge of the body portion, and a second sidewall extending outward from the second side edge of the body portion. In addition, a first set of raised portions protrude from a first interior surface of the first sidewall, and a second set of raised portions protrude from a second interior surface of the second sidewall, where the first interior surface and the second interior surface face toward one another and wherein two or more of the raised portions of the first set of raised portions differ in three-dimensional shape.

A kit of parts, in accordance with a second aspect of this disclosure, includes a portable computing device with a display housing with a first side and an opposite-facing second side, the first side including a base portion and a receiving portion that is recessed relative to the base portion, the second side including a display panel. The kit of parts also includes a first interchangeable housing component as described here above, sized and dimensioned to be removably attached to the receiving portion, the first interchangeable housing component including a body portion with an upper surface and an opposite-facing lower surface, and further comprising a third sidewall extending outward from the forward edge of the body portion, the third sidewall being disposed between the first sidewall and the second sidewall, wherein the first sidewall, the second sidewall, and the third sidewall are joined to form a substantially continuous U-shaped sidewall, the U-shape sidewall extending around three sides of the body portion. In addition, the receiving portion includes an interface surface that is exposed until the first interchangeable housing component is removably attached to the display housing.

In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings. In the following material, indications of direction, such as "top" or "left," are merely to provide a frame of reference during the following discussion, and are not intended to indicate a required, desired, or intended orientation of the described articles.

Computing devices such as tablet computers, laptops, and other smart devices have been increasingly moving toward an all-day everyday reliance by end-users, where users carry their devices through their normal routines and activities, similar to a handbag or wallet. However, this trend is associated with challenges, as these devices can be viewed as reflections of the user's personal tastes and outlook. In a work meeting for example, a user may wish to interact with a well-kept, professional, or otherwise sharp-looking device, while at social events occurring the same day, the same user may wish their device to clearly showcase their interests, preferences, and/or favorite subjects. As noted above, there is a need for such devices to readily adapt to modifications in appearance. The following description discloses systems and methods for providing users with simple, quick, and easy to implement changes to device appearance. In different implementations, the following systems can provide a relatively simple means of switching the appearance of their device from a first 'costume' to a second 'costume' while retaining the integrated, seamless feel of the device as a whole. Specifically, an easy-to-remove-and-replace reusable housing panel component for a computing device will be described. For example, a first component with a first appearance and properties can be detached from an external surface of the computing device, and a second component with a second appearance and properties can be attached to the same computing device, such that the appearance of the computing device is substantially altered. The device can also be quickly returned to its original appearance. In addition, the device can be configured to receive a plurality of different components and, with each new attachment (or re-attachment), appear to become for all intents and purposes a different device. Such appearance swaps can allow a user to enjoy the benefit of a single device with the ability to rapidly morph in appearance to better reflect the user's expectations across a wide range of occasions. Furthermore, this type of arrangement allow the user to more readily express individuation, art, or advertising that is functional, removable, and compatible with the computer's functions, screen visibility, ability to close, and ability to be transported with ease.

It should be understood that while the following implementations will be described in the general context of a laptop computer, the systems may be applicable to numerous other electronic devices such as PDAs, MP3 players, remote controls, gaming interfaces, digital cameras, mobile phones, tablets, and other computer related devices such as flat panel monitors, computer monitors, medical devices, point of sale terminals, and other relatively man-portable or mobile computing devices.

The following description presents interchangeable housing systems for use with computing devices. In order to better introduce the systems and methods to the reader, <FIG> present a high-level example of a representative system <NUM> providing an interchangeable housing component for a portable computing device ("device") <NUM>. <FIG> depicts one implementation of the device <NUM> that includes a display housing that has an outer or external upper section (first side) comprising a base portion <NUM> and an adjacent receiving portion <NUM>. In this case, the device <NUM> includes a first component <NUM> that serves as a portion of the larger housing for the lid (e.g., the display unit) of the device <NUM>, where the lid contains or houses a display panel for the device <NUM>, and is joined (for example, by a hinge or other pivoting connection mechanism) to a keyboard and/or main body unit of the computing device.

In some implementations, the receiving portion <NUM> is recessed relative to the base portion <NUM>, and is also configured to receive and secure an additional component (here, an interchangeable housing panel component). In different implementations, the receiving portion <NUM> can be sized and dimensioned to receive and/or be detached from an interchangeable housing component. In some implementations, the device <NUM> will not appear 'complete' or fully assembled until a candidate housing panel component is also secured to the receiving portion and covers the exposed region. The sequence of <FIG> present one example of a process in which a first housing component installed on the device <NUM> is replaced by a second, different housing component. The display housing of the device <NUM> also includes an opposite-facing second side that can support, frame, contain, enclose, and/or house the display panel for the computing device. In other words, the first side of the display housing comprises the backside or rear structure of the display panel for the device. Thus, although the drawings do not illustrate in detail the display panel, it is to be understood that all computing devices described herein include a computing display-screen panel. The interchangeable housing panel components refers to candidate housing cover components that may be installed on the display housing that is supporting, surrounding, enclosing and/or containing an integrated display panel for viewing content being displayed by the device (such as a lid for a laptop or notebook computing device).

In <FIG>, a first component <NUM> is being pulled or slid distally outward by a user <NUM> (e.g., toward the body of the user <NUM>), or along a direction moving away from the device <NUM> that is generally aligned with a lateral axis <NUM>. In some cases, the user <NUM> may first exert a gentle downward pressure on the first component <NUM> (i.e., in a downward direction generally aligned with a vertical axis <NUM>) prior to or as the first component <NUM> is slid away from the device <NUM> in order to facilitate release of the first component <NUM> from the attachment mechanisms that were securing the first component <NUM> to the receiving portion <NUM> of the device <NUM>. In another example, the user <NUM> may exert a gentle inward or proximal pressure on the first component <NUM> (i.e., in a downward pressing in towards the center of the component) prior to or as the first component <NUM> is slid away from the device <NUM> in order to facilitate release of the first component <NUM> from the attachment mechanisms that were securing the first component <NUM> to the receiving portion <NUM> of the device <NUM>. Once the first component <NUM> is loosened or detached from the device <NUM>, it may be pulled upward as well to fully remove or uninstall the housing component, revealing or exposing an outer surface of the receiving portion <NUM>.

For consistency and convenience, some directional adjectives are employed throughout this detailed description corresponding to the illustrated embodiments. The term "longitudinal" as used throughout this detailed description and in the claims refers to a direction extending a length of a component. For example, the longitudinal direction of the first component <NUM> and/or device <NUM> may extend between a first side <NUM> and a second side <NUM>. Also, the term "lateral" as used throughout this detailed description and in the claims refers to a direction extending along a width of a component. For example, the lateral direction of the first component <NUM> and/or device <NUM> may extend between a rearward side <NUM> and a forward side <NUM>. Additionally, the term "vertical" as used throughout this detailed description and in the claims refers to a direction that is perpendicular to both the longitudinal and lateral directions. For example, the vertical direction of sole system <NUM> may extend through the thickness of the first component <NUM> and/or device <NUM>. In addition, the term "proximal" refers to a portion of a component that is closer to a central region of the component. Likewise, the term proximal direction refers to a direction oriented towards the central region. The term "distal" refers to a portion of a component that is further from the central region. The distal direction refers to a direction oriented away from the central region. As used herein, the "central region" could be the center of mass and/or a central plane and/or another centrally located reference surface of the component or device.

In <FIG>, the first component <NUM> has been removed from the device <NUM>, and the receiving portion <NUM> now presents an exposed surface <NUM> that was previously disposed beneath, adjacent to, facing toward and/or contacting the lower surface or underside of the first component <NUM>. In addition, a second component <NUM> is also introduced, with similar proportions to the first component <NUM>. However, it may be understood that although the first component <NUM> and the second component <NUM> can include similar fastening or attachment mechanisms (as will be described in greater detail herein), each component can otherwise differ greatly in appearance, material composition, and other physical or structural properties. Simply as an example, the first component <NUM> may comprise a rigid external material that is hard to the touch, while the second component <NUM> may comprise a fabric, or other more compressible or elastic material. In another example, the first component <NUM> may include a printing, tint, logo, or other artistic illustration or ornamentation, while the second component <NUM> includes embroidery or different textile-based designs and/or patterns (or vice-versa).

In <FIG>, an installation or attachment stage is depicted, in which the second component <NUM> is now being slid or otherwise connected with the device <NUM>. The second component <NUM> may be an entirely new component (i.e., has never been used with this device before) or may be a component that was previously attached to this device but was removed and is now being re-used. In this example, the second component <NUM> is being pushed or slid onto the receiving portion <NUM> by the user <NUM> in a direction away from the body of the user <NUM>, or along a direction toward the device <NUM> that is generally aligned with a lateral axis <NUM>. In some cases, the user <NUM> may also exert a gentle downward pressure on the second component <NUM> (i.e., in a downward direction generally aligned with a vertical axis <NUM>) prior to or as the second component <NUM> is slid onto or toward the device <NUM> in order to facilitate a latching or secure receipt of the second component <NUM> via the same or substantially similar attachment mechanisms that were securing the first component <NUM> to the receiving portion <NUM> of the device <NUM> earlier.

Thus, as will be described in greater detail below, a display housing of the device <NUM> can be configured to receive and integrate multiple types of display housing components that can significantly affect the external appearance of the device. In other words, there can be a plurality of interchangeable housing components that can each be removably or releasably attached to the device. For purposes of comparison, FIG. ID depicts the device <NUM> with the first component <NUM> installed and <FIG> depicts the device <NUM> with the second component <NUM> installed, each being associated with a different outer appearance that can be suitable for different types of events or occasions.

As a general matter, the phrase "removably attached" or interchangeable refers to components that are designed for repeated installation and removal. Thus, "removably attached" shall refer to the joining of two components in a manner such that the two components are secured together, but may be readily detached from one another, and again secured together if so desired. Non-limiting examples of removable attachment mechanisms may include hook and loop fasteners, friction fit connections, interference fit connections, threaded connectors, cam-locking connectors, and other such readily detachable connectors. Similarly, "removably disposed" shall refer to the assembly of two components in a non-permanent fashion.

In contrast, the term "fixedly attached" shall refer to two components joined in a manner such that the components may not be readily separated (for example, without destroying one or both of the components). Exemplary non-limiting modalities of fixed attachment may include joining with permanent adhesive, rivets, stitches, nails, staples, welding or other thermal bonding, or other joining techniques. In addition, two components may be "fixedly attached" by virtue of being integrally formed, for example, in a molding process.

In other words, the interchangeable components described herein are configured to be repeatedly fasten or be secured to a device via various attachment mechanisms, and are further configured for repeated release or detachment from the device. Furthermore, the components may be installed on one device, and then removed and installed on a second, different device. As an example, a user may swap housing components between two laptops, or share components with friends or other users with devices configured to connect to the interchangeable components. In some implementations, the devices described herein may be understood to comprise a female connector or mechanism that is configured to receive the housing component comprising a corresponding 'male' connector. More specifically, the interchangeable component can be configured to be received by the 'receptacle' of the female-end provided by the receiving portion of the device. In other words, the device (in this case, the receiving portion) and interchangeable component may each be sized and dimensioned to permit the interchangeable component to be snugly inserted and/or securely received by the device.

In order to provide further context for the uses and applications of the systems described herein, <FIG> present a non-limiting example of an interchangeable housing panel component ("housing panel" or "housing component") <NUM> that can be used in conjunction with a housing of various computing devices. In <FIG>, a top-down view of the housing panel component <NUM> is provided, and in <FIG>, a bottom-up view of the housing panel component <NUM> is provided. In other words the two figures show two views of the same component, one directed to a top side or upper surface <NUM> (<FIG>), and the other is directed to a bottom side or a lower surface <NUM> (<FIG>). In <FIG>, the housing panel component <NUM> includes a substantially continuous peripheral (outermost) edge-band extending around the outer periphery of the panel. The edge-band can be understood to comprise a first side edge ("first edge") <NUM>, a second side edge ("second edge") <NUM>, a rearward edge <NUM>, and a forward edge <NUM> that collectively provide an outer perimeter or boundary of a body portion <NUM> of the housing component. In different implementations, the upper surface <NUM> can include any material or design, and can be selected and/or customized to reflect the preferences of a user. Furthermore, the upper surface <NUM> provides the external or outermost surface of the component, such that, when installed, the upper surface <NUM> remains exposed or visible, while the lower surface <NUM> is configured to face toward the receiving portion of the device and is therefore hidden, covered, or otherwise not intended to be visible to a user once the component is installed. In addition, the housing panel component <NUM> can be seen to include a length <NUM> extending from the first edge <NUM> to the second edge <NUM> (along longitudinal axis <NUM>), and a width <NUM> extending from the rearward edge <NUM> to the forward edge <NUM> (along lateral axis <NUM>).

In different implementations, the housing panel component <NUM> can include provisions for removable attachment to a device. As a first example of such a mechanism, a plurality of tab portions <NUM> can be seen extending upward from the rearward edge <NUM> of the housing panel component <NUM>. These tab portions <NUM>, as well as other fastening mechanisms, will be described in detail below.

In <FIG>, the housing component has been 'flipped' over to illustrate the lower surface <NUM> (an opposite facing surface relative to the upper surface) and offer the reader an introductory view of the fastening mechanisms that may be included in the housing component. For example, as shown in <FIG>, the housing panel component <NUM> also includes a first sidewall <NUM> extending distally outward (here, in a direction vertically upward, toward the viewer) from the first edge <NUM> of the body portion <NUM>, and a second sidewall <NUM> extending distally outward (here, in a direction vertically upward, toward the viewer) from the second edge <NUM>. In addition, the housing panel component <NUM> includes a third sidewall <NUM> that extends distally outward (here, in a direction vertically upward, toward the viewer) from the forward edge <NUM> of the body portion <NUM>. In the example of <FIG>, both the first sidewall <NUM> and the second sidewall <NUM> extend along a direction that is aligned with the lateral axis <NUM>. In one implementation, the first sidewall <NUM> and the second sidewall <NUM> are substantially parallel. Furthermore, the third sidewall <NUM> in this example extends along a direction that is aligned with the longitudinal axis <NUM>. In one implementation, the third sidewall <NUM> can be oriented orthogonally relative to the first sidewall <NUM> and/or the second sidewall <NUM>.

In some implementations, these three sidewalls (<NUM>, <NUM>, <NUM>) can be joined together or otherwise be configured to extend along the peripheral edge as a single piece to form a substantially continuous, U-shaped peripheral sidewall, as shown in <FIG>. While in <FIG>, the U-shape includes curved connector regions (i.e., a first connector region <NUM> and a second connector region <NUM>), in other implementations the sidewalls may end more sharply and join or merge together at right-angles instead.

In some implementations, the sidewalls can be associated with one or more connector elements that enable or otherwise facilitate the fastening or securement between the housing panel component <NUM> and the device and these connector elements, together with corresponding connector elements on the device itself, serve as attachment mechanisms. As a general matter, these connector elements can involve a mating connection process, in which a first connection element of the interchangeable housing panel component is mated, inserted, joined, contacted, secured to, or otherwise becomes removably connected with a second connection element of the computing device. However, it should be understood that the connector element properties described herein can also incorporate additional fastening elements, such as but not limited to magnetic or other self-mating connector materials, clasps, hook and loop fasteners, snap fasteners, screws, buckles, sliders, or other connection components. These connector elements, as will be discussed in greater detail below, provide a balance between ease of installation and mating with a computing device, and reliability and durability of installation. In other words, the various types of connector elements described herein are (a) simple to secure together (installation involves a quick slide-and-click on process), (b) dependable once secured (e.g., remaining firmly attached to the device throughout everyday use and transport of that device, and also providing a resilient component that can be maintained for the life of the device), and (c) straightforward to remove for a user (quick and simple disconnect process). In addition, by arranging connector elements along all four edges of the housing panel component, the stability or anchoring of the housing panel component to the device is ensured. Furthermore, the types of connector elements and their specific structures are designed to make installation straightforward and easy, but inadvertent removal much more unlikely. For example, the mechanisms are oriented in a way that requires a user to exert a specific sequence of applied pressure and force to disengage the various connector elements that have been mated with one another, such that removal or loosening of the housing panel component from the device is highly unlikely to occur accidentally.

Referring to <FIG>, the first sidewall <NUM> includes a first set of raised portions <NUM> protruding from a first interior surface <NUM> of the first sidewall <NUM>, where the first interior surface <NUM> is an opposite facing surface of a first exterior surface <NUM> of the first sidewall <NUM>. Similarly, the second sidewall <NUM> includes a second set of raised portions <NUM> protruding from a second interior surface <NUM> of the second sidewall <NUM>, where the second interior surface <NUM> is an opposite facing surface of a second exterior surface <NUM> of the second sidewall <NUM>. In different implementations, the third sidewall <NUM> includes a group of projections <NUM> protruding from a third interior surface <NUM> of the third sidewall <NUM>, where the third interior surface <NUM> is an opposite facing surface of a third exterior surface <NUM> of the third sidewall <NUM>. It can be seen that the raised portions can include different sizes or dimensions in some implementations. For example, some raised portions may extend further proximally inward than neighboring raised portions (as shown in <FIG>). Additional details regarding the raised portions will be provided with reference to <FIG>, and additional details regarding the projections <NUM> will be provided with reference to <FIG>. While not shown here, the connector elements described herein can be further associated with magnetic elements that can help guide or facilitate the attachment process between the housing panel component and the display housing.

In different implementations, connector elements can also be provided that are not associated with a sidewall. For example, in <FIG>, the housing panel component <NUM> includes plurality of tab portions <NUM> that extend in an outward direction (distally) away from the body portion <NUM>. These tab portions <NUM> are anchored or integrally formed along the rearward edge <NUM>. In some implementations, the tab portions can be made of the same material as the body portion, while in other implementations, the material can differ. Additional details regarding the tab portions <NUM> will be provided with reference to <FIG>.

Furthermore, in the example of <FIG>, the first interior surface <NUM> and the second interior surface <NUM> can be observed to face toward one another. In some implementations, these two sets of raised portions (<NUM>, <NUM>) are arranged in a substantial mirror-image positioning relative to one another. However, in other implementations, one or both of the sidewalls <NUM> and <NUM> may be oriented diagonally relative to the lateral axis <NUM>, or otherwise include curvature or non-linear portions, and the raised portions arranged along each sidewall can be vary in their spatial position. In another example, the two side portions as demarcated by a lateral-midline along the body portion <NUM> can be symmetrical with respect to one another.

Referring now to <FIG>, further information pertaining to the raised portions introduced above is provided. In <FIG>, a side view of the housing panel component <NUM> is illustrated along the lateral axis <NUM> of <FIG> in which the second interior surface <NUM> of the second sidewall <NUM> is visible. In <FIG>, the arrangement of the second set of raised portions <NUM> can be more clearly observed. In this specific example, the second set of raised portions <NUM> comprises six raised portions, including a first raised portion <NUM>, a second raised portion <NUM>, a third raised portion <NUM>, a fourth raised portion <NUM>, a fifth raised portion <NUM>, and a sixth raised portion <NUM>. In different implementations, there may be fewer or greater number of raised portions. In addition, it may be seen that each raised portion is substantially similar in three-dimensional shape relative to the other raised portions. In this case, each raised portion has a generally trapezoidal or quadrangular shape. However, as shown in <FIG>, the extent that each raised portion is 'raised' beyond the sidewall surface or otherwise protrudes can differ. Though not observable in the side views of <FIG>, referring back to <FIG>, it may be seen that first raised portion <NUM>, third raised portion <NUM>, and fifth raised portion <NUM> each have a first width W1 and the second raised portion <NUM>, fourth raised portion <NUM>, and sixth raised portion <NUM> each have a larger, second width W2. Thus, an internal volume of each of the first raised portion <NUM>, third raised portion <NUM>, and fifth raised portion <NUM> will be smaller than an internal volume of each of the second raised portion <NUM>, fourth raised portion <NUM>, and sixth raised portion <NUM>. In other words, the extent that each raised portion protrudes outward or away from the sidewall can vary.

As depicted in an enlarged view <NUM> of the first raised portion <NUM>, the raised portion may include a slanted or sloped edge <NUM> that is oriented diagonally relative to the remaining three edges. This sloped edge <NUM> is provided toward the side that will initially engage with the corresponding mechanisms of the receiving portion of a device, and can allow the slide-in and slide-out processes to occur more smoothly and easily for the user. in other words, the direction of the slant, where the sloped edge increases in height from a lower point to a higher point, is configured to enable or facilitate the guidance of the raised portion into the specially shaped recesses that may be formed in the receiving portion of the device (see <FIG>). In some other implementations, the raised portion may include curved or rounded, rather than sharp, edges. In addition, it may be understood that the thickness of each raised portion can vary and can be configured to match or generally 'fit' the depth of its corresponding recess in the receiving portion.

Furthermore, in different implementations, the materials comprising the housing panel component <NUM> can vary, and may incorporate a single primary material, or multiple materials with varying properties. In <FIG>, for purposes of illustration, the housing panel component <NUM> includes three materials, including a first material <NUM> corresponding to the upper (outermost, exposed, or external) surface <NUM> that extends across the body portion <NUM> and in some cases over the edges and along the surfaces of the sidewalls (see <FIG>), a second material <NUM> corresponding to an intermediate or substrate layer of the component. In some implementations, another, third material <NUM> corresponding to the material of the sidewalls can also be used. It is to be understood that the differences in cross-hatching are presented for purposes of example only, and in different implementations, the material comprising the entirety or substantial entirety of the housing panel component <NUM> can be a single, uniform material (see <FIG>), or only two materials (see <FIG>), or three or more materials. In this example, the first material <NUM> may be a soft fabric or textile, wood (or artificial wood laminate or other laminates), thermoplastic, or leather, the second material <NUM> may be configured to provide structural support (such as a plastic molding), and an optional third material may be more rigid to withstand the repeated engagements as it functions to support various attachment mechanisms.

In different embodiments, each of the materials can include various properties. In some implementations, the various portions of the housing panel component may be formed from one or more of a plurality of material elements (e.g., textiles, polymer sheets, foam layers, leather, synthetic leather, knitted fabrics, etc.) that are stitched together or otherwise laid or disposed adjacent to one another to form the housing panel component. Other materials that could be used in various implementations include, but are not limited to: expanded rubber, foam rubber, various kinds of foams, polyurethane, nylon, Gore-Tex, leather, plastic, textiles, as well as possibly other materials. Other parts of the housing panel components may be made from any of a plurality of materials or combination of materials, such as leather, leather-like materials, polymer materials, plastic materials, and textile fabrics and materials. Such materials can offer a more pleasing aesthetic appearance and feel to the housing panel component, which can be of great importance to a user.

In addition, each of the layers comprising the housing panel component may be formed from any generally two-dimensional material. As utilized with respect to the present invention, the term "two-dimensional material" or variants thereof is intended to encompass generally flat materials exhibiting a length and a width that are substantially greater than a thickness. Accordingly, suitable materials for at least the body portion of the housing panel component (whether comprising one or multiple layers), and/or the sidewalls, include various textiles, polymer sheets, or combinations of textiles and polymer sheets, for example.

Textiles are generally manufactured from fibers, filaments, or yarns that are, for example, either (a) produced directly from webs of fibers by bonding, fusing, or interlocking to construct non-woven fabrics and felts or (b) formed through a mechanical manipulation of yarn to produce a woven or knitted fabric. The textiles may incorporate fibers that are arranged to impart one-directional stretch or multidirectional stretch, and the textiles may include coatings that form a breathable and water-resistant barrier, for example. The polymer sheets may be extruded, rolled, or otherwise formed from a polymer material to exhibit a generally flat aspect. Two-dimensional materials may also encompass laminated or otherwise layered materials that include two or more layers of textiles, polymer sheets, or combinations of textiles and polymer sheets. In addition to textiles and polymer sheets, other two-dimensional materials may be utilized for housing panel component or portions thereof (e.g., the outermost covering or first layer <NUM>). Although two-dimensional materials may have smooth or generally untextured surfaces, some two-dimensional materials will exhibit textures or other surface characteristics, such as dimpling, protrusions, ribs, or various patterns, for example. Despite the presence of surface characteristics, two-dimensional materials remain generally flat and exhibit a length and a width that are substantially greater than a thickness. In some configurations, mesh materials or perforated materials may be utilized in the housing panel component.

Furthermore, in some implementations, at least the outer surface of the housing panel component (the surface that is visible after installment on a device) can be treated to provide various external appearances to the material. For example, a molding texture, embossing, metal wire drawing, painting, printing, water transfer printing, hot press forming, texturing (e.g. leather grain), hot stamping, laser engraving, metal etching, metal stamping, silk-screen printing, and/or techniques based on IML (In Molding Label), IMF (In Molding Film), IMR (In Molding Roller), OMD (over-molding or high-pressure transfer), OMR (over-molding release or release film) VCM plates and boards (vinyl chloride), and/or CNC machining.

In some implementations, dissimilar materials described herein may be attached by fusing or welding. As utilized herein, the terms "fusing" and "welding" (and variants thereof) are defined as a securing technique between two elements that involves a softening or melting of the material of at least one of the elements such that the materials of the elements are secured to each other when cooled. Similarly, the term "weld" or variants thereof is defined as the bond, link, or structure that joins two elements through a process that involves a softening or melting of material within at least one of the elements such that the elements are secured to each other when cooled. Welding may involve the melting or softening of two components such that the materials from each component intermingle with each other, that is, the materials may diffuse across a boundary layer (or "heat affected zone") between the materials, and are secured together when cooled. Alternatively, welding may involve the melting or softening of a material in a first component such that the material extends into or infiltrates the structure of a second component, for example, infiltrating crevices or cavities in the second component or extending around or bonding with filaments or fibers in the second component to secure the components together when cooled. Thus, welding of two components together may occur when material from one or both of the components melts or softens. Accordingly, a weldable material, such as a polymer material, may be provided in one or both of the components. Additionally, welding does not generally involve the use of stitching or adhesives, but involves directly bonding components to each other with heat. In some situations, however, stitching or adhesives may be utilized to supplement the weld or the joining of the components through welding. Components that have been welded together will be understood to be "fused" together.

In different implementations, modern embroidery techniques may be utilized to autonomously create an embroidery pattern on a sheet of textile materials that is incorporated into the outermost surface of the housing panel component. Textile materials include fabrics such as cotton, wool or silk, as well as leather, foam, polymer sheets, and synthetic equivalents. Other examples of materials that may be utilized include polyester, nylon, polypropylene, polyethylene, acrylics, wool, acetate, polyacrylonitrile, and combinations thereof. Natural fibers may also be used, such as cellulosic fibers (e.g., cotton, bamboo) or protein fibers (e.g., wool, silk, and soybean).

On the textile materials, a number of stitch techniques may be used. For example, depending on the purpose of the embroidery, the chain stitch, the buttonhole or blanket stitch, the running stitch, the satin stitch, or the cross stitch may be used to produce various designs. The stitching techniques may be used in combination to form a variety of set patterns. The stitching patterns may be decorative, for example the pattern may form a flower or series of flowers, logos, alphanumeric symbols, customized designs, or other patterns. Alternatively the stitching may be structural, such as stitching along the edges of a garment to reinforce the seams. In further cases the stitching may be both decorative and functional, such as the use of a floral pattern use to reinforce a patch.

Typically a thread or yarn is used as the stitching material and stitched into the textile. Commonly the thread or yarn may be made of cotton or rayon, as well as traditional materials like wool, linen or silk. However, embroidery may also sew in dissimilar materials to the textile, usually for decorative purposes. For example, thread created out of precious metals such as gold or silver may be embroidered within more traditional fabrics such as silk. Additionally, additional elements may be sewn in during embroidery, such as beads, quills, sequins, pearls or entire strips of metal. These elements may be sewn in along with yarn or thread using variety of stitching techniques depending on the desired placements of the elements.

In other examples, the materials can be arranged differently. For example, the outermost covering can include a material that only serves as the upper surface <NUM>, while the exterior surfaces of the sidewalls are formed of a different material In other implementations, the outermost covering can include a material that covers the upper surface <NUM> and also curves or wraps around (or 'hugs') some or all of the exterior surfaces of the first and second sidewalls, providing a more continuous interface. For example, a ledge portion <NUM> extending toward the forward edge <NUM> configured to form a forward facing exterior surface (e.g., a surface facing toward the user <NUM> of <FIG>) can include the same material extending along the upper surface <NUM>, or - as shown in <FIG> - can be of a different material entirely. In some other implementations, the two materials may similar, but be of different colors or patterns, providing users with greater design choices. In addition, in some implementations, the raised portions can include a fourth type of material, or may extend outward from the sidewall with the same material as the sidewall. In another example the raised portions may be formed of the material providing the substrate and the sidewalls may include a plurality of apertures shaped and sized to allow the raised portions to pass through the apertures as they extend outward from the substrate.

It can further be understood that when multiple layers of materials are incorporated into an interchangeable housing component, the materials can vary in their relative thicknesses. It should also be understood that the interchangeable cover dimensions can be adjusted to accommodate different sized laptops or other computing devices for which the housing panel component is desired. Any other sized-computing device can also benefit from these interchangeable components; as the device size increases, the housing panel component dimensions can also change.

With respect to interchangeable housing panel components that are integrally formed (i.e., as one piece or primarily being made of a single material), for example by plastic molding, the thickness of the plastic can vary relative to the computing device dimensions (see <FIG>). As a specific example, a Z-height (vertical axis) of a first computing device may be around <NUM>, and a corresponding interchangeable housing panel component may have a thickness of approximately <NUM>. In another example, a Z-height (vertical axis) of a second computing device may be around <NUM>, and a corresponding interchangeable housing panel component may have a thickness of approximately <NUM>.

With respect to interchangeable housing panel components that include an outer cover material and an internal substrate or support structure, the dimensions can vary to accommodate the differences in materials. For example, a first housing panel component can include an upper surface wrap cover that includes two primary materials, where a soft, flexible material, such as a fabric, is wrapped around a more rigid supporting base (see <FIG>). In another example, a second housing panel component can include a primary surface recessed design, where there is a slight recessed region along the upper surface of rigid supporting base that is configured to receive versatile decorated materials of a thickness matching the depth of the recess (see <FIG>). As a further example, a third housing panel component can be configured to receive a `wrap around cover' that extends around the sidewalls as well as the upper surface (see <FIG>), suitable for soft, flexible material(s) being wrapped around a more rigid supporting base. These softer covers can have a smaller thickness relative to the more rigid substrate. For example, the softer outer material can have a thickness of approximately <NUM> to <NUM>, and a substrate thickness ranging between <NUM> and <NUM>. Where the first computing device had a Z-height of around <NUM>, the corresponding interchangeable housing panel component comprising two materials may have a first material thickness of approximately <NUM> and a second material thickness of approximately <NUM> or <NUM>. In another example, where the Z-height (vertical axis) of the second computing device is around <NUM>, the corresponding interchangeable housing panel component comprising two materials may have a first material thickness of approximately <NUM> and a second material thickness of around <NUM> or <NUM>. Such dimensions can provide a balance between the durability and sturdiness of the housing panel component, as it undergoes repeated removals and installations, as well as an outer appearance and texture that is pleasing to the user.

While the bottom-up view of <FIG> appeared to show the raised portions on each of the first sidewall <NUM> and the second sidewall <NUM> as being arranged in a single line, <FIG> more clearly shows that in some implementations, the arrangement can vary widely. Specifically, in <FIG>, the second sidewall <NUM> is shown in two parts to better illustrate one possible arrangement of the raised portions. In <FIG> a forward portion of the housing component is shown and in <FIG> a rearward portion of the housing component is shown. The second sidewall <NUM> includes the six raised portions of the second set of raised portions <NUM>. It can be seen that in different implementations, two or more of the raised portions can be disposed at varying heights along the sidewall relative to vertical axis <NUM>.

For purposes of reference, in <FIG>, the first raised portion <NUM> is disposed at a first height H1 along the second sidewall <NUM>, the second raised portion <NUM> is disposed at a second height H2, the third raised portion <NUM> is disposed at a third height H3. Similarly, in <FIG> the fourth raised portion <NUM> is disposed at a fourth height H4 along the second sidewall <NUM>, the fifth raised portion <NUM> is disposed at a fifth height H5, and the sixth raised portion <NUM> is disposed at a sixth height H6. While in some implementations the heights H1-H6 can be the same, in other implementations, two or more may differ. In <FIG>, while the first height H1 and the third height H3 are substantially similar or equal, the second height H2 is smaller than either H1 or H3. In addition, in <FIG>, while the fourth height H4 and the sixth height H6 are substantially similar or equal, the fifth height H5 is greater than either H4 or H6. In addition, in this example, heights H1, H3, and H5 are approximately equal, and heights H2, H4, and H6 are approximately equal. This produces a staggered height pattern, and in this specific case, a repeated "high-low" alternating pattern for the raised portions. This pattern will be again reflected in the discussion of the receiving portion for the device (see <FIG> and <FIG>). In other words, the raised portions can be arranged to correspond to any spatial pattern that will align with, for example, the arrangement of corresponding receiving notches or recesses in the device to ensure a secure connection between the two sections (see <FIG>).

Furthermore, in some implementations, the second sidewall <NUM> may also include additional fastening mechanisms. In <FIG> and <FIG> an elongated flange portion <NUM> is depicted near the forward edge <NUM>, spaced apart slightly from the ledge portion <NUM>. As will be illustrated further below, the flange portion <NUM> can be sized and dimensioned to slide into a corresponding slot of the device (see <FIG>) and help complete or finalize the connection process.

As introduced above, the housing panel component <NUM> also includes the plurality of tab portions <NUM> arranged along the forward edge <NUM>. As the housing panel component <NUM> is inserted onto or into the receiving portion of a device, when it nears the base portion, the tab portions <NUM> can be aligned with corresponding recessed slots formed in portions of both of the rearmost surface of the receiving portion as well as the base portion (see <FIG>). In one implementation, the tab portions can be configured to provide a snap-fit connection with the recessed slots. Referring to the isolated view of <FIG>, in this case the tab portions <NUM> include a first tab <NUM>, a second tab <NUM>, a third tab <NUM>, a fourth tab <NUM>, a fifth tab <NUM>, a sixth tab <NUM>, and a seventh tab <NUM>. In different implementations, there may be fewer or greater number of tab portions. In addition, it may be seen that each tab portion is substantially similar in three-dimensional size and dimensions relative to the other tab portions. In this case, each tab portion has a generally rounded rectangular (tab) shape. In <FIG>, the second tab <NUM> and the third tab <NUM> are illustrated in an enlarged view <NUM> for the reader's benefit. The second tab <NUM> has a length <NUM> extending along the longitudinal axis <NUM> that is greater than its width <NUM> extending along the lateral axis <NUM>. In different implementations, the length <NUM> will be similar to a length of a recessed slot in the device configured to receive the tab portion, and the width <NUM> will be similar to a width of the recessed slot. In some other implementations, though, the width <NUM> may be smaller than the width of the recessed slot, whereby the recessed slot is slightly larger to allow for the smooth passage of the tab into the rearmost portion of the recessed slot. Furthermore, an overall thickness of the tab portion can be similar to the depth of the recessed slot such that there is a flush and secure fit when the two pieces are joined.

Each of the tab portions are joined to the rearward edge <NUM> by a series of rib elements. For example, in the enlarged view <NUM>, three rib elements <NUM> extend distally outward from the lower surface <NUM> of the body portion <NUM>. A back edge <NUM> of the second tab <NUM> is then integrally attached with a distal end of each of the three rib elements <NUM>. This type of elastic strut-like mechanical structure is important in that it allows the tab portion to move up and down within a limited range of flexibility to facilitate the insertion of the tabs into their corresponding recessed slots that are disposed or formed below the larger outer surface of the receiving portion of the device. For example, if the ribs instead comprised a larger, one-piece or otherwise bulkier 'bridge', there might be a greater likelihood of damage or break between a tab and the body portion <NUM>. This rib arrangement permits gentle 'bounce' or yielding as the user slides the housing panel component into place. Once the tabs are received by the recessed slots, there may be a click, or locking step.

In addition, in this case, it can be understood that each of the plurality of tabs <NUM> lie along a different horizontal plane (lower with respect to the vertical axis) than the horizontal plane of the body portion <NUM>. Such an arrangement also allows the final connection between the housing panel component and the device to appear more seamless, as the tabs are received by slots that are at least partially beneath or within the base portion and therefore hidden from view once the housing panel component is fully connected.

Also introduced above, the housing panel component <NUM> includes the group of protruding portions <NUM> arranged along the forward edge <NUM>. As the housing panel component <NUM> is inserted onto or into the receiving portion of a device, when it nears the final stage of installation, the protruding portions <NUM> can be aligned with corresponding apertures that are formed in the forward-facing side of the receiving portion (see <FIG>).

With reference to the isolated view of <FIG>, in this example the protruding portions <NUM> include a first protruding portion <NUM>, a second protruding portion <NUM>, a third protruding portion <NUM>, a fourth protruding portion <NUM>, a fifth protruding portion <NUM>, a sixth protruding portion <NUM>, a seventh protruding portion <NUM>, and an eighth protruding portion <NUM>. In different implementations, there may be fewer or greater number of protruding portions. In addition, it may be seen that while some protruding portions are substantially similar in three-dimensional size and dimensions relative to other protruding portions, other protruding portions differ. In this case, each protruding portion has a generally rounded prism shape. In addition, second protruding portion <NUM>, third protruding portion <NUM>, sixth protruding portion <NUM>, and seventh protruding portion <NUM> are substantially equal in size and shape, while being larger in thickness, length, and width from the other four protruding portions. Similarly, fourth protruding portion <NUM> and fifth protruding portion <NUM> are substantially equal in size and shape, while being smaller in thickness and width from the four protruding portions <NUM>, <NUM>, <NUM>, and <NUM>. Finally, first protruding portion <NUM> and eighth protruding portion <NUM> are substantially equal in size and shape, while being smaller in thickness, length, and width from the two protruding portions <NUM> and <NUM>. In some implementations, the arrangement of the protruding portions as demarcated by a lateral-midline along the body portion <NUM> can be symmetrical with respect to one another, as shown in <FIG>, providing a more even weight distribution that can improve user experience during installation and removal operations.

In <FIG>, the third protruding portion <NUM>, fourth protruding portion <NUM>, and fifth protruding portion <NUM> are shown in an enlarged view <NUM> for the reader's benefit. The third protruding portion <NUM> has a first length <NUM> extending along the longitudinal axis <NUM> that is greater than its first width <NUM> extending along the lateral axis <NUM>. Similarly, the fourth protruding portion <NUM> has a second length <NUM> that is greater than its second width <NUM>. Relative to one another, the first length <NUM> is similar to the second length <NUM>; however, the first width <NUM> is larger than the second width <NUM>. In different implementations, as will be discussed below with reference to <FIG>, the apertures formed in the device configured to receive each of these protruding portions can be sized and dimensioned to snugly match the particular three-dimensional shape and size of each corresponding protruding portion and permit a secure lock between the two components.

Referring now to <FIG>, the sequence of drawings present a non-limiting example of a housing for a device that can be used in conjunction with the interchangeable housing panel components described herein. In <FIG>, a top-down view of a portable computing device ("device") <NUM> is shown (without the housing panel), including a display housing (e.g., the housing portion for the lid of the device that holds the display screen) that comprises both a base portion <NUM> and a receiving portion <NUM>. In different implementations, the proportion of surface area associated with each portion can differ. For example, in <FIG>, the base portion <NUM> has a first surface area that extends across a first lateral distance <NUM>, and the receiving portion <NUM> has a second, larger surface area that extends across a second lateral distance <NUM>. In some implementations, the first surface area of the base portion <NUM> can be equal to or less than the second surface area of the receiving portion. This arrangement can ensure that a significant extent of the lid is customizable with an interchangeable housing panel component. In <FIG>, the second surface area of the receiving portion <NUM> is approximately twice as large as the first surface area of the base portion <NUM>. In other words, the first surface area comprises approximately <NUM>/<NUM> of the total surface area of the exterior surface of the display rear (backside of the display) housing or lid portion <NUM>, and the second surface area comprises approximately <NUM>/<NUM> of the total surface area for the lid portion <NUM>.

For purposes of reference, the device <NUM> has a first side <NUM>, a second side <NUM>, a rearward side <NUM>, and a forward side <NUM>. The base portion <NUM> is disposed nearer the rearward side <NUM> of the device <NUM> and the receiving portion <NUM> is disposed nearer the forward side <NUM> of the device <NUM>. In addition, the base portion <NUM> includes a generally rectangular prism shape, and comprises a plurality of external surfaces. In this example, the base portion <NUM> has a top surface <NUM> that extends between a first side surface <NUM> (disposed along the first side <NUM> of the device <NUM>) and a second side surface <NUM> (disposed along the second side <NUM> of the device <NUM>) relative to the longitudinal axis <NUM>. In addition, the top surface <NUM> of the base portion <NUM> extends between a third side surface <NUM> (disposed along the rearward side <NUM>), and a fourth side surface <NUM> (disposed directly adjacent to the receiving portion <NUM>) relative to the lateral axis <NUM>. Each of the side surfaces extend along a generally vertical plane, in contrast to the top surface <NUM> which extends along a generally horizontal plane. The fourth side surface <NUM> can be configured to receive or be pressed against a rearward edge <NUM> (see <FIG>) of the housing panel component when the housing panel component is installed.

In other words, the base portion <NUM> is thicker than the receiving portion <NUM> (i.e., relative to the vertical axis), and the receiving portion <NUM> is recessed or 'thinner' relative to the base portion <NUM>. In some implementations, the difference in thickness between the receiving portion <NUM> and the base portion <NUM> can correspond to a thickness of the housing panel component that is to be accommodated by the device, resulting in a smooth, flush interface between the outer surface of the rearward edge of the housing panel component and the fourth side surface <NUM>. Thus, when there is no housing panel component installed, the fourth side surface <NUM> is exposed and visible, and when a housing panel component is installed, the fourth side surface <NUM> is no longer visible. This can be seen more clearly in the views provided by <FIG> and <FIG>, where a thickness T1 and a thickness T2 are labeled for purposes of clarity to highlight the difference in thickness between the base portion <NUM> and the adjacent receiving portion <NUM>.

Similarly, in some implementations, the length of the base portion <NUM> (relative to the longitudinal axis <NUM>) can be greater than a length of the receiving portion <NUM>. This can be observed in <FIG> along the first side <NUM>, where a first side portion <NUM> of the base portion <NUM> extends a first length L1 distally outward, and in <FIG> along the second side <NUM>, where a second side portion <NUM> of the base portion <NUM> extends a second length L2 distally outward, relative to the receiving portion <NUM>. In other words, each of the two side portions of the base portion <NUM> jut outward relative to the receiving portion <NUM>, each with surface areas sufficient to provide an interface for the rearmost ends of the first and second sidewalls of the housing panel component when the housing panel component is installed.

An introductory view of the fastening mechanisms that may be incorporated in device <NUM> for attachment to a housing panel component is also provided in <FIG>. In this example, the receiving portion <NUM> has an interface surface <NUM> configured to receive or contact the lower surface <NUM> of the housing panel component. The interface surface <NUM> extends between a first periphery <NUM> (disposed along the first side <NUM> of the device <NUM>) and a second periphery <NUM> (disposed along the second side <NUM> of the device <NUM>) relative to the longitudinal axis <NUM>. In addition, the interface surface <NUM> of the receiving portion <NUM> extends between a third periphery <NUM> (disposed adjacent to the fourth side surface <NUM> of the base portion <NUM>), and a fourth periphery <NUM> (disposed along the forward side <NUM>) relative to the lateral axis <NUM>.

As noted earlier, the receiving portion <NUM> can include provisions for removable attachment with an interchangeable housing panel component. In general, these provisions can be arranged to correspond directly with specific connector elements formed on the housing panel component. Some examples of these provisions include a plurality of recessed slots ("slots") <NUM> arranged along the border associated with third periphery <NUM>. In some implementations, the slots <NUM> can extend beyond the region corresponding to the receiving portion <NUM> and be formed within parts of the base portion itself (see <FIG> below). In addition, along the first periphery <NUM> of the receiving portion <NUM>, a first set of grooves <NUM> is formed, and along the second periphery <NUM> a second set of grooves <NUM> is formed. As a general matter, these grooves can be positioned to receive the raised portions described earlier with respect to <FIG>. Furthermore, though not visible in <FIG>, a group of apertures can also be formed along the fourth periphery <NUM> of the receiving portion <NUM> that are configured to snugly receive the group of protruding portions of the housing panel component (see <FIG>).

Referring now to <FIG>, further information pertaining to the sets of grooves introduced above is provided. In <FIG>, an isolated top-down view of the first periphery <NUM> of the receiving portion <NUM> is shown, and in <FIG>, a side view of the first periphery <NUM> is shown. The first set of grooves <NUM> comprises six grooves, including a first groove <NUM>, a second groove <NUM>, a third groove <NUM>, a fourth groove <NUM>, a fifth groove <NUM>, and a sixth groove <NUM>. While in some implementations the grooves can be substantially similar in size and shape, in this case, it can be seen that the relative positions and sizes of the grooves vary in an alternating pattern, similar to that described earlier with respect to the raised portions of <FIG>. As a first example, the first groove <NUM> has a first depth D1, and the second groove <NUM> has a second depth D2. In this case, the second depth D2 is deeper or extends further than the first depth D1. This arrangement is repeated, where it may be understood that third groove <NUM> and fifth groove <NUM> also each have a depth corresponding to the first depth D1, and the fourth groove <NUM> and sixth groove <NUM> each have a depth corresponding to the second depth D2. This variation in depths permits the raised portions - positioned at varying heights along the sidewalls of the housing panel component, to be received by the groove during the initial stage of the installation process and appropriately guided into their respective secured positions, as will be discussed below with reference to <FIG>.

In some implementations, the receiving portion <NUM> may also include provisions for `locking' or finalizing the connection between the housing panel component and the device. As described earlier in <FIG>, in some implementations, the housing panel component can include a flange portion disposed toward the forward edge near the first sidewall and/or a flange portion disposed toward the forward edge near the second sidewall. In one implementation, the receiving portion can include a channel <NUM> along the first periphery <NUM> (toward the forward side <NUM>) configured to receive a first flange portion and, as shown in <FIG>, a second channel <NUM> along the second periphery <NUM> configured to receive a second flange portion. In different implementations, such flange portions can be sized and dimensioned to bend elastically before being received by the channels.

For purposes of comparison, in <FIG>, an isolated top-down view of the second periphery <NUM> of the receiving portion <NUM> is shown, and in <FIG>, a side view of the second periphery <NUM> is shown. The second set of grooves <NUM> comprises six grooves, including a seventh groove <NUM>, an eighth groove <NUM>, a ninth groove <NUM>, a tenth groove <NUM>, an eleventh groove <NUM>, and a twelfth groove <NUM>. In some implementations, the two sides depicted in <FIG> can be understood to represent structural mirror-images of one another However, in other implementations, each side can include variations in structure, and be modified as needed to correspond to changes in the size, shape, or positions of the raised portions along the sidewalls of the housing component.

In order to provide the reader with a greater appreciation of the function of each groove, an isolated isometric view of two of the grooves is illustrated in <FIG>. In this example, the tenth groove <NUM> and neighboring eleventh groove <NUM> are shown. The isometric view reveals more clearly the L-shape of each groove. In other words, each groove includes a main chamber or first segment that is in direct fluid communication with the opening formed on the upward-facing interface surface <NUM> and extends downward through the side of the receiving portion, as well as a more elongated arm chamber that extends in a rearward direction from and in fluid communication with the main chamber. In <FIG>, the tenth groove <NUM> has a first receiving segment <NUM> (main chamber) and a first securing segment <NUM> (arm chamber), and the eleventh groove <NUM> has a second receiving segment <NUM> (main chamber) and a second securing segment <NUM> (arm chamber). Each of the main chambers can differ in shape, but can be generally configured to serve as the initial receiving region of the raised portion during installation, as well as the removal route for the same raised portion during removal. Similarly, each of the arm chambers can differ in shape, but can be generally configured to serve as the final locking region once the housing panel component is installed, and will hold or be a receptacle for the raised portion during the duration of the housing panel component's installation on the device.

In <FIG>, the first receiving segment <NUM> has a depth corresponding to second depth D2 and the second receiving segment <NUM> has a depth corresponding to first depth D1, which is smaller than second depth D2. In addition, the first securing segment <NUM> has a depth corresponding to a third depth D3, and the second securing segment <NUM> has a depth corresponding to a fourth depth D4. In different implementations, the depth D3 can be approximately equal to a total height of the raised portion that is to be inserted into the first securing segment <NUM>. Similarly, the depth D4 can be approximately equal to a total height of the raised portion that is to be inserted into the second securing segment <NUM>. In some implementations, depths D3 and D4 can be similar. The first depth D1 extends from the interface surface <NUM> to a first bottom surface <NUM>, and the second depth D2 extends from the interface surface <NUM> to a second bottom surface <NUM>. Similarly, the third depth D3 extends from a topmost surface of the first securing segment <NUM> to the second bottom surface <NUM>, and the fourth depth D4 extends from a topmost surface of the second securing segment <NUM> to the first bottom surface <NUM>. Finally, the <NUM> is associated with a third width W3 and the <NUM> is associated with a fourth width W4. In this case, third width W3 is smaller than fourth width W4. These widths can correspond to the relative widths of the raised portions, as described above with respect to <FIG>. In other words, the raised portions that protrude outward less (e.g., first raised portion <NUM>, third raised portion <NUM>, and fifth raised portion <NUM> with a first width W1) will be received by a correspondingly narrower groove (e.g., with width W3), and the raised portions that protrude outward further (e.g., second raised portion <NUM>, fourth raised portion <NUM>, and sixth raised portion <NUM> with larger, second width W2) will each be received by a correspondingly wider groove (e.g., with width W4) to ensure a snug fit for each sized-connector element.

Referring now to <FIG>, further information about the plurality of recessed slots <NUM> arranged along the border associated with third periphery <NUM> is provided. In this example, the slots <NUM> include a first slot <NUM>, a second slot <NUM>, a third slot <NUM>, a fourth slot <NUM>, a fifth slot <NUM>, a sixth slot <NUM>, and a seventh slot <NUM>. In different implementations, there may be fewer or greater number of recessed slots. In addition, in <FIG>, each slot is substantially similar in three-dimensional shape and size relative to the other slots. In this example, each slot has a generally rectangular cross-sectional shape, and has a similar depth as its neighboring slots. However, in other implementations, the extent that each slot is recessed relative to the interface surface <NUM> can vary in order to accommodate any corresponding variations in the thickness of a tab portion that will be received by the slot (see <FIG>).

As noted above, in some implementations, the slots <NUM> can extend beyond the receiving portion <NUM> and be formed within parts of the base portion <NUM> itself. An enlarged transparent view <NUM> of second slot <NUM> is provided as a simplified example. In view <NUM>, the second slot <NUM> has a first portion <NUM> associated with or formed in the receiving portion <NUM>, and a second portion <NUM> that is in fluid communication with the first portion <NUM> but is associated with or formed in the base portion <NUM> (now transparent). In other words, the recessed slot can extend further inward, into the base portion <NUM>. Thus, when a tab portion is inserted into the recessed slot during an installation, the tab portion will initially slide or move through the first portion <NUM> and then be at least partially received by the second portion <NUM>.

<FIG> offers additional detail regarding a group of apertures <NUM> formed in the fourth periphery <NUM> of the receiving portion <NUM> in a top-down view <NUM> and a side view <NUM>. These apertures <NUM> can be sized and dimensioned to receive or mate with the group of protruding portions extending from the forward edge of the housing panel component (see <FIG>). Thus, for each protruding portion, there is a corresponding aperture. In this example, as there were eight protruding portions described earlier, there are now eight apertures, including a first aperture <NUM>, a second aperture <NUM>, a third aperture <NUM>, a fourth aperture <NUM>, a fifth aperture <NUM>, a sixth aperture <NUM>, a seventh aperture <NUM>, and an eighth aperture <NUM>. The number and placement of each aperture can vary in different implementations to correspond to the arrangement of protruding portions for the housing component. It may further be understood that while some apertures are substantially similar in three-dimensional size and dimensions relative to other apertures, other apertures differ. In this case, each aperture has a generally rectangular cross-sectional shape. In addition, second aperture <NUM>, third aperture <NUM>, sixth aperture <NUM>, and seventh aperture <NUM> are substantially equal in size and shape, while being larger in depth (volume) from the other four protruding portions. Similarly, fourth aperture <NUM> and fifth aperture <NUM> are substantially equal in size and shape, while being smaller in depth (volume) from the four apertures <NUM>, <NUM>, <NUM>, and <NUM>. Finally, first aperture <NUM> and eighth aperture <NUM> are substantially equal in size and shape, while being smaller in volume from the two apertures <NUM> and <NUM>.

For purposes of clarity, the installation process is depicted in greater detail with reference to <FIG>. In <FIG>, an overview of the process in three general stages is shown with a series of side views. A first stage in <FIG> represents an initial stage during which the two components (e.g., housing panel component <NUM> and a display housing or lid portion <NUM> of device <NUM>) are moved toward one another. In this example, the housing panel component <NUM> approaches the lid portion <NUM> and is also moved in a downward direction toward the interface surface <NUM> of the receiving portion <NUM>. The two components can also be oriented together along the horizontal axis, such that the edges are generally aligned. The second stage of <FIG> represents an intermediate or transition stage during which the connection elements are initially inserted or where the male connection element begins a final approach toward its corresponding female receptacle. This stage usually is associated with a termination of the movement of the components toward one another along the vertical axis. The third stage of <FIG> represents the secure or installed stage in which the housing panel component <NUM> is moved into a final position by a last push inward or a movement of the components toward one another along the lateral axis. During the third stage the housing panel component <NUM> is securely attached to the lid portion <NUM> of the device <NUM>. In order to release the housing panel component, the sequence can be reversed, whereby the housing panel component <NUM> is pulled outward or away from its secure connection with the lid portion <NUM> (<FIG>), shown loosened in the second stage (<FIG>), and removed with an upward and away motion back to the uninstalled or initial stage (<FIG>). However, the removal will also require the application of a gentle pressure inward, applied against the first side and the second side (e.g. along a horizontal direction, proximally inward) to loosen the attachment mechanisms prior to and/or during the removal process. Thus, in different implementations, while the installation can involve a more straightforward 'sliding on until secure' process, the removal (sliding off) cannot be initiated until a gentle pressure is also applied along both of the first sidewall and the second sidewall. This pressure loosens or de-couples the mating between the raised portions and their corresponding grooves and ensures that removal does not occur inadvertently.

<FIG> provide an enlarged view of the second and third stages shown in <FIG>. For clarity in the illustration, the housing panel component and device lid portion have been segmented into two portions (a rear portion and a forward portion). In <FIG>, a rear portion of the housing panel component <NUM> and a rear portion of the lid portion <NUM> are shown, and in <FIG>, the remaining or corresponding forward portion of the housing panel component <NUM> and a forward portion of the lid portion <NUM> are shown. Referring first to <FIG>, the rear portion of the housing panel component <NUM> has been slid, pressed, inserted, 'dropped', or otherwise conveyed onto the rear portion of the interface surface <NUM> of the receiving portion <NUM> with respect to the vertical axis <NUM>. Each raised portion of the second set of raised portions protruding from the second sidewall has been introduced into their corresponding grooves. Specifically, in <FIG>, the first raised portion <NUM> has been received by the first groove <NUM>, the second raised portion <NUM> has been received by the second groove <NUM>, and the third raised portion <NUM> has been received by the third groove <NUM>. At this time, although some of the connecting elements have been inserted into or made contact with their respective receptacles, the housing panel component <NUM> remains unsecure, and a gap <NUM> between the fourth side surface <NUM> of the base portion <NUM> and the rearward <NUM> of the housing panel component <NUM> remains in which a portion of the interface surface <NUM> is exposed. In <FIG>, following a final push or gentle force applied to continue the attachment process, it can be observed that the three raised portions have been guided further into the groove, and moved a distance in a rearward direction along the lateral axis <NUM> into the respective securing segments of each of the grooves (see <FIG>). Once this occurs, the raised portion is 'locked' in place, the housing panel component <NUM> has been fully fastened, and the two component remain mated, unless a force is applied to remove the housing panel component <NUM> from the device <NUM> (e.g., during an un-installment).

At the same time, referring to <FIG>, the forward portion of the housing panel component <NUM> is depicted slid, pressed, inserted, 'dropped', or otherwise conveyed onto the forward portion of the receiving portion <NUM>. Each raised portion of the second set of raised portions protruding from the second sidewall has been guided into their corresponding grooves. Specifically, in <FIG>, the fourth raised portion <NUM> has been received by the fourth groove <NUM>, the fifth raised portion <NUM> has been received by the fifth groove <NUM>, and the sixth raised portion <NUM> has been received by the sixth groove <NUM>. At this time, although some of the connecting elements have been inserted into or made contact with their respective receptacles, the housing panel component <NUM> remains unsecure or only partially installed. In <FIG>, following a final push or gentle force applied to continue the attachment process, it can be observed that the three raised portions have been guided further into the groove, and moved a distance in a rearward direction along the lateral axis <NUM> into the respective securing segments of each of the grooves (see <FIG>). Once this occurs, the raised portion is 'locked' in place, the housing panel component <NUM> has been fully fastened, and the two component remain mated, unless a force is applied to remove the housing panel component <NUM> from the device <NUM> (e.g., during an un-installment). In some implementations, the flange portion <NUM> can also be received by the channel <NUM> which can help anchor the ledge portion <NUM> of the housing panel component <NUM>. It is to be understood that while only the raised portions along one sidewall were illustrated for purposes of simplicity, the other connector elements (i.e., tab portions and recessed slots, protruding portions and apertures, and the raised portions of the opposing sidewall with their corresponding grooves), will also be joined together during this process, and secured as described herein. In other implementations, fewer types of fastening mechanism may be used than what is shown in the drawings. For example, in some implementations, a housing panel component may only include the raised portions, without the tab portions or the protruding portions. In another example, a housing panel component may not include the protruding portions. In some implementations, the tab portions and protruding portions may be included, while no raised portions are present. The device's receiving portion can be configured according to the desired connection mechanisms formed in the housing panel components.

Referring now to <FIG>, one implementation of a retail system <NUM> is depicted. In some implementations, portable computing devices <NUM> are sold simultaneously with complementary pre-packaged interchangeable housing panel components of varying appearance and comprising varying materials. In this figure, the retail system <NUM> is shown as part of a wall <NUM>. In different implementations, this wall <NUM> would be a portion of a retail store or other sale place for merchandise. In other implementations of a retail system there may be no wall <NUM>, or the components may be displayed or offered by other means. The portable computing devices and associated components are shown generically in <FIG> only for the purpose of illustration. In some embodiments, the housing panel components may be different styles and colors. Each pre-packaged interchangeable housing panel component (here a first housing panel component <NUM>, a second housing panel component <NUM>, and a third housing panel component <NUM>) includes a ready-to-install housing panel component that reflects a particular design or appearance type.

In different implementations, using a retail system, a user could purchase a computing device, and select an additional housing panel component from the group of housing panel components that have been designed and pre-packaged as per their preference. By associating a housing panel component with a device, and attaching that housing panel component by the mechanisms described herein, the user may modify a device themselves, to provide varying appearance and texture types.

In some situations, it may be preferable for a user to purchase multiple pre-packaged housing panel components, such as first housing panel component <NUM> and second housing panel component <NUM>, at one time. Using a retail system like the one illustrated in <FIG>, a user could purchase a computing device <NUM> and two or more pre-packaged housing panel components. This would permit the user to swap the housing panel components at desired occasions, and return the device to its original appearance at any time. Additionally, housing panel components can be easily portable in the sense that they are small compared to the size of the computing devices, which is already being transported by the user. This feature may allow the user to modify the appearance of the device at any time and at various locations and/or events.

<FIG> illustrates an isometric view of a kit of parts ("kit") <NUM>. In some implementations, the kit may comprise at least one computing device <NUM>, accessories for the computing device (here interchangeable components including a first housing panel component <NUM> and a second, different housing panel component <NUM>), and/or a container <NUM> for storing the device and accessories. In other implementations, kit could include any other provisions not discussed below including but not limited to: instructions, electrical connectors and cords, headsets, speakers, various kinds of media (such as CDs, DVDs, etc.), additional storage containers for storing device <NUM> and/or device accessories as well as any other provisions. Generally, the device <NUM> associated with the kit may be any type of computing device configured to accommodate the housing panel components described herein.

Kit <NUM> may be offered for sale at a retail location, as discussed previously. Kit may also be offered for sale at a kiosk, factory outlet, manufacturing store, and/or through an online vendor. In some implementations, the various parts of kit are sold together. In other implementations, some parts of kit may be sold separately. As an example, the current implementation of <FIG> depicts kit of parts <NUM> including container <NUM>, computing device <NUM>, first housing panel component <NUM>, and second housing panel component <NUM>. In other embodiments, a retailer could sell a kit including device <NUM> and only one housing panel component. In other cases, a retailer could sell a kit including device <NUM> and three or more housing panel components. In other implementations, the retailer could sell one or more other housing panel components separately from the kit.

Furthermore, kit <NUM> may include container <NUM>. Container <NUM> can be any type of container configured to store computing device and accessories. In some embodiments, container <NUM> may be a box In one embodiment, container <NUM> may be a carrying case that is configured to transport the computing device and accessories. In some embodiments, container <NUM> may have a generally rectangular shape, and can include a lower portion and a lid. In other embodiments, container <NUM> could be a bag, sack, or other type of container. In other embodiments, the various items in the kit may not be provided in a container <NUM>.

While various embodiments have been described, the description is intended to be exemplary, rather than limiting, and it is understood that many more embodiments and implementations are possible that are within the scope of the embodiments. Although many possible combinations of features are shown in the accompanying figures and discussed in this detailed description, many other combinations of the disclosed features are possible.
