Description

[Technical Field]

[0001] The present disclosure relates to aerosol generating devices and to aspects of housings for such devices, and more particularly to housings for Tobacco Heated Product (THP) devices. [Background technology]

[0002] Smoking articles, such as cigarettes and cigars, burn tobacco during use to produce tobacco smoke. Attempts have been made to provide alternatives to these tobacco-burning articles by creating products that release compounds without combustion. An example of such a product is a heating device that releases compounds by heating but not burning a material. The material may be, for example, tobacco or other non-tobacco products, and may or may not contain nicotine.

[0003] These heating devices may include a housing that holds internal components that are held by a user. Summary of the Invention

[0004] An aerosol generating device may include a housing that contains some or all of the components for generating an aerosol from received consumables. Parts of the device housing are held by a user when the device is carried or used to generate an aerosol. Thus, the particular form of the housing can affect or improve the usability of the device.

[0005] The housing of the device is used to house the aerosol-generating components and functions and to isolate some components from the user. Therefore, the shape and size of the housing can also affect the basic function of the device. For example, a device that generates aerosol by heating a tobacco product in a non-combustion heating configuration can include a housing that houses a power source, circuitry, and some form of heating zone. Devices such as THP devices can have numerous components that must be housed and isolated from the user.

[0006] For example, the ease of use of the device can be improved by providing a housing with a shape that substantially matches the shape of the housing as it is grasped by a user's hand. The housing may be flat or have a curved surface so that it can be easily held or gripped in the hand.

[0007] Therefore, the configuration of the housing, including its shape and size, can affect both the ease of use of the device and the accommodation of the aerosol generating functions. As such, certain housing configurations and shapes may be particularly desirable or advantageous for one or more particular types of aerosol generator. In particular, a combination of a flat exterior surface and a convex exterior surface may be particularly easy to grip during use of the device while providing space for accommodating certain components.

[0008] The housing may include features that provide the device with an improved "user feel" by improving tactile feedback to the user. For example, the use of particular materials in parts of the housing may impart a feel or tactile feedback that the user may associate with the high quality or robustness of the device, or that the user finds enjoyable or pleasant.

[0009] Haptic feedback can be particularly affected by the surface texture of the housing components. For example, a surface with a relatively high degree of texture can impart the feel of an easy-to-grip device and provide a reassuring haptic feedback. In another example, a relatively smooth surface (i.e., with relatively little roughness) can impart a solid feel and give the impression of a high-quality or robust device.

[0010] It may be desirable to provide a housing with different tactile textures in different locations to provide a user with an overall impression and varied tactile feedback. The housing may comprise multiple surfaces with different textures, e.g., textures with different roughnesses from one another. In one example, surfaces with a relatively greater roughness may be provided in areas of the housing intended to be gripped or held by a user, while surfaces with a relatively lesser roughness may be used in areas surrounding user interface means such as buttons.

[0011] It would therefore be advantageous to provide an aerosol generating device, a housing for an aerosol generating device, or a component of such a housing, that is configured for ease of use, houses the aerosol generating function, and provides an improved user experience.

[0012] More specifically, it may be desirable to provide these benefits in the context of heated tobacco (THP) devices, which may have a relatively large number of internal components that must be isolated from the user and, therefore, may have several elements of size, shape, and external configuration that are unique to that type of device.

[0013] To provide an improved user experience and allow users to customize the device, modular, removable housing components may be provided. The removable housing components may form side panels of the aerosol generating device that are attached or detached by the user beyond the top of the device's base housing that houses the components. The user may attach, detach, and exchange different removable housing components according to the user's preferences, for example, to customize the texture of various parts of the housing.

[0014] One removable housing component may include a side panel having a substantially curved, convex shape that conforms to a user's grip. This section of the housing may have a particular impact on the overall user experience, as the convex exterior surface is what is most likely to be held or gripped by the user during use of the device. Therefore, it may be particularly desirable to provide this section of the housing with a customizable surface, such as a textured surface.

[0015] It is desirable for removable housing components and underlying fittings to be easily attached and detached while still providing a strong connection to one another. It is also advantageous to be able to configure the amount of friction that occurs between components during attachment and detachment, as friction can create tactile feedback to the user and provide an improved impression of the robustness of the device and connection.

[0016] It is also desirable to provide removable housing components and device housings that can be easily mass-produced. Therefore, it is beneficial to be able to control gaps that may form between the removable components and the basic housing to account for manufacturing tolerances.

[0017] According to a first aspect of the present disclosure, there is provided a removable housing component for attachment to a housing of an aerosol generating device, the removable housing component having a first end and a second end, the component extending between the first end and the second end to define a component axis, a concave inner surface having a concave outer shape in a direction along the component axis, and a first plurality of elongated protrusions extending from the concave inner surface and spaced apart from each other in a direction along the component axis.

[0018] In a further embodiment, the removable housing component may further comprise a second plurality of elongated protrusions extending from the concave interior surface and spaced apart from one another in a direction along the component axis, the second plurality of protrusions being spaced apart from the first plurality of protrusions in a direction perpendicular to the axis.

[0022] In a further embodiment of any of the foregoing embodiments, the removable housing component may further comprise a convex exterior surface opposing the concave interior surface.

[0023] In a further embodiment of any of the foregoing embodiments, the convex outer surface comprises a texture that differs from the texture of the concave inner surface.

[0024] According to a further aspect of the present disclosure, there is an aerosol generating device comprising a housing having a first end and a second end, the housing extending between the first end and the second end to define a device axis, a convex outer surface having a convex profile in a direction along the device axis, and a first plurality of channels extending through the convex surface into the housing and spaced apart from each other in a direction along the device axis.

[0025] In a further embodiment, the aerosol generating device may further comprise a second plurality of channels extending within the convex outer surface and spaced apart from one another in a direction along the device axis, the second plurality of channels being spaced apart from the first plurality of channels in a direction perpendicular to the axis.

[0026] In a further embodiment of any of the preceding embodiments, each of the first plurality of channels comprises a planar support surface facing in a first direction, and each of the second plurality of channels comprises a planar support surface facing in a second direction opposite and away from the first plurality of channels.

[0027] In a further embodiment of any of the foregoing embodiments, each channel of the first plurality of channels and the second plurality of channels comprises a lip on one side of the channel, the lip extending from a planar support surface facing the first direction and the second direction.

[0028] In a further embodiment of any of the preceding embodiments, each of the first plurality of channels comprises a planar support surface facing a common direction, and each of the second plurality of channels comprises a planar support surface facing the same direction.

[0029] In a further embodiment of any of the foregoing embodiments, each channel of the first plurality of channels and the second plurality of channels comprises a first planar support surface and a second planar support surface that are at an angle to each other and meet at an edge within the channel.

[0030] According to a further aspect of the present disclosure, the aerosol generating device of any of the aforementioned embodiments may further comprise the removable housing component of any of the aforementioned embodiments, wherein the first plurality of protrusions are received within the first plurality of channels so as to removably attach the housing component to the housing.

Detailed Description of the Drawings

[0036] FIG. 1 shows an aerosol generating device 100 and a modular housing component 200 that is removably attached to the device 100 .

[0037] The exemplary aerosol-generating device 100 is a heated tobacco (THP) device. The device 100 includes internal components (not shown) including a power source and a heating zone. The internal components may include an induction heater for heating the heating zone. The internal components are received within a device housing 102, which substantially surrounds or encloses the internal components such that the internal components are contained within the device 102. The device housing 102 substantially surrounds and encloses the internal components in three dimensions.

[0038] The device 100 further includes a container (not shown) for receiving the consumable product. In the illustrated example, the container is formed substantially within the device housing 102. A container opening 104 is formed in the device housing 102 and connects the container to the exterior of the device 100.

[0039] During use, a user may insert a consumable into the container of device 100 through container opening 104. In the illustrated example, the container is shaped such that the inserted consumable is only partially received within the container, with a portion of the consumable remaining outside of device 100 on the opposite side of container opening 104.

[0040] The heating zone is associated with the container such that the heating zone is configured to heat the consumable received in the container. When the device 100 is activated, the power source provides heat to the heating zone, which heats the consumable received in the container and generates an aerosol from the consumable. In the illustrated example, a user may inhale the aerosol from a portion of the consumable that is external to the device.

[0041] In other examples, the aerosol generating device may comprise a device configured to generate an aerosol from a liquid precursor material that is at least partially received within a similar device housing, with an opening in the housing provided for insertion of the material and / or for inhalation of the resulting aerosol by a user.

[0042] FIG. 2 shows the device housing 102 receiving the housing component 200. FIG. 3 shows the device housing 102 and the removably attachable housing component 200 separated from each other. The housing component 200 is attachable to the base device housing 102 by a user, as described further below. The device housing 102 is a base housing that receives the internal components of the aerosol generating device that are to be isolated from the user, and provides a means for receiving the removable housing component 200. In the attached position, the housing component 200 covers a portion of the device housing 102. Thus, a user can attach and remove the housing component 200 from the device housing 102 without exposing any of the internal components of the device.

[0043] As best seen in FIG. 2 , device housing 102 defines a device axis X extending longitudinally or lengthwise through the center of device 100. Device housing 102 includes a first or proximal end 106 and a second or distal end 108 separated longitudinally along axis X. First end 106 corresponds to the end of the device at which a user may inhale aerosol generated by the device. A container opening of the device is formed at the end of the device corresponding to first end 106 of device housing 102. Second end 108 corresponds to the opposite end of the device, substantially the end of the device farthest from a user when the user inhales the generated aerosol from the device.

[0044] The device housing 102 includes sidewalls 110 that form a hollow shell extending longitudinally between open ends. The hollow interior of the device housing 102, bounded by the sidewalls 110, receives the internal components of the device 100 described above. The sidewalls 110 extend from the first end 106 to the second end 108 of the device 100. The sidewalls 110 extend completely about the axis X. The housing 102 is hollow, and the sidewalls 110 of the housing 102 define an interior space 112 between the first end 106 and the second end 108 that can receive the internal components of the device 100 therein.

[0045] The device housing 102 may further include first and second end walls (not shown) corresponding to the first end 106 and second end 108, respectively. The first and second end walls join to side walls 110 at the first end 106 and second end 108 of the device 100 to cover or close the interior space of the device housing 102. The side walls 110 and the first and second end walls together form a substantially three-dimensional outer shell for receiving and enclosing the internal components of the device 100. During assembly of the device, the internal components may be positioned and placed within the side walls 110 before one or both of the end walls are attached to the side walls 110. This arrangement provides ease of manufacturing and assembly.

[0046] The sidewall 110 is joined or connected to both the first and second end walls of the housing 102 to form the device housing 102 in the assembled device. The sidewall 110 may be connected to either of the end walls by being integrally formed therewith. Alternatively, the sidewall 110 may be connected to one or both of the end walls by a non-removable or permanent attachment means, such as an adhesive or mechanical interlock.

[0047] The terms "non-removably connected" or "non-removable", as used herein, are taken to mean that the connected elements cannot be separated without damaging the attachment means, and thus the elements cannot be reattached by the same attachment means without repair.

[0048] In the illustrated example, the sidewall 110 of the device housing 102 is integrally formed as a unitary component. In other examples, the sidewall 110 comprises multiple pieces joined by non-removable attachment means.

[0049] The integral formation and / or non-removable attachment of the first and second end walls and side wall 110 of the device housing 102 prevents or limits a user's ability to disassemble or access internal components of the device housing 102. This may help to avoid exposure of the user to heated or electrical components within the device 102, or may help to prevent the user from accidentally disassembling or destroying the device 102.

[0050] As best seen in FIG. 3 , sidewall 110 comprises a plurality of exterior surfaces that are also exterior surfaces of device housing 102. The plurality of exterior surfaces includes surfaces that are exposed to a user when the device is fully assembled. The plurality of surfaces includes one or more surfaces that are intended to be exposed during normal use of the device and at least one surface that may be covered by a modular housing component 200 that is removably attachable by a user to the assembled device prior to use of the device. The plurality of exterior surfaces are differently shaped and positioned to facilitate attachment / detachment of the modular housing component and / or to provide a suitable configuration for user handling during use.

[0051] The multiple exterior surfaces are surfaces facing the interior space 112 defined by the side wall 110. In other words, the multiple exterior surfaces are surfaces of the side wall 110 that are separated from the interior space 112 in the thickness direction of the side wall 110.

[0052] Figure 4 shows the device housing 102 in a view taken along section AA of Figure 3. The plurality of exterior surfaces comprises a first exterior surface 114 having a first portion 118, a second portion 120, and a third portion 122 that bound different portions of the surface. The first exterior surface 114 is the surface exposed to a user during use, and the first portion 118, the second portion 120, and the third portion 122 are shaped to conform to a user's grip.

[0053] The first exterior surface 114 is generally continuous across the first portion 118, the second portion 120, and the third portion 122. That is, the portions 118, 120, and 122 are smoothly joined and are not separated by edges or other surface features. The first portion 118 and the second portion 120 have a flat or planar shape. In this regard, the first portion 118 and the second portion 120 are generally tangential to a circumferential direction about the axis X. The first portion 118 and the second portion 120 are separate from each other on opposite sides of the device housing 102. The first portion 118 and the second portion 120 are separate and disposed on opposite sides of the device housing 102, separated by the interior space 112.

[0054] The third portion 122 extends between the first portion 118 and the second portion 120 and joins the first portion 118 and the second portion 120 to form the first exterior surface 114. The third portion 122 forms a curved or arcuate surface. The third portion 122 has a convex shape and defines a curved surface having an exterior inflection point. The third portion 122 is convex in a direction along the axis X so as to form a convex longitudinal profile or convex shape when viewed in the direction of the axis X. The third portion 122 forms a substantially complete arc shape and may have a substantially constant curvature throughout the substantially complete arc shape.

[0055] The curved and convex shape of the third portion 122 of the first exterior surface 114 can be defined in terms of a center of curvature. The third portion 122 of the first exterior surface 114 faces away from the center of curvature and defines a convex shape. The third portion 122 can extend approximately 180 degrees, or between 160 and 200 degrees, around the center of curvature to form a substantially complete arc.

[0056] The first portion 118, second portion 120, and third portion 122 of the first exterior surface 114 form a continuous surface, i.e., portions 118, 120, 122 are not separated by discontinuities, such that the first exterior surface 114 comprises at least two relatively planar portions joined by a relatively curved or arcuate portion.

[0057] The plurality of exterior surfaces of the side wall further comprises a second exterior surface 116. The second exterior surface 116 may be covered by a modular housing component in use and is shaped to receive the modular housing component.

[0058] The second exterior surface 116 is similar to the third portion 122 of the first exterior surface 114 in that it forms a curved or arcuate surface. The second exterior surface 116 has a convex shape and defines a curved surface having an external inflection point. The second exterior surface 116 is convex in a direction along the axis X so as to form a convex longitudinal profile or convex shape when viewed in the direction of the axis X. The second exterior surface 116 may form a substantially complete arc shape and may have a generally constant curvature throughout the substantially complete arc shape.

[0059] The curved and convex shape of second exterior surface 116 can be defined in terms of a center of curvature. Second exterior surface 116 faces away from the center of curvature and defines a convex shape. Second exterior surface 116 can extend approximately 180 degrees, or between 160 and 200 degrees, around the center of curvature to form a substantially complete arc.

[0060] The second exterior surface 116 is disposed on the opposite side of the device housing 102, opposite a similarly shaped third portion 122 of the first exterior surface 114, and is separated from the third portion 122 by the interior space 112.

[0061] The first exterior surface 114 and the second exterior surface 116 are separated from one another by first and second abutments or ledges 124, 126 formed in the sidewall 110. The first and second ledges 124, 126 partially define a recess 128 for receiving the modular housing component 200 on the device housing 102.

[0062] First ledge 124 and second ledge 126 provide a discontinuity in the exterior of sidewall 110 separating first exterior surface 114 and second exterior surface 116 such that second exterior surface 116 is recessed relative to first exterior surface 114. Thus, housing component 200 can be received on second exterior surface 116 at ledges 124, 126 so as to be flush with first exterior surface 114.

[0063] Each of the ledges 124, 126 includes a pair of edges, each edge separating the respective ledge 124, 126 from one of the first exterior surface 114 and the second exterior surface 116. The edges extend longitudinally of the device housing 102. The edges are formed where one of the first ledge 124 and the second ledge 126 intersects with the first exterior surface 114 or the second exterior surface 116. The first ledge 124 separates the second exterior surface 116 from the first portion 118 of the first exterior surface 114. The second ledge 126 separates the second exterior surface 116 from the second portion 120 of the first exterior surface 114. The ledges 124, 126 are formed inwardly of the first exterior surface 114. That is, the ledges 124 , 126 extend inward toward the interior space 112 of the housing 102 .

[0064] The ledges 124, 126 may be formed by variations in thickness of the sidewall 110. In the illustrated example, the sidewall 110 includes a relatively thin portion separated by the ledges 124, 126 from a relatively thicker portion, the thinner portion defining the second exterior surface 116 and the thicker portion defining the first exterior surface 114.

[0065] The ledges 124, 126 and the second exterior surface 116 define a recess 128 in the housing sidewall 110. The recess 128 is recessed relative to the first exterior surface 114 and provides an arc- or crescent-shaped area of ​​empty space on the exterior of the device housing 102. The recess 128 extends across the second exterior surface 116 between the first ledge 124 and the second ledge 126. The ledges 124, 126 thereby space the first exterior surface 114 outwardly from the second exterior surface 116.

[0066] 3 , the configuration of first exterior surface 114 and second exterior surface 116, and first ledge 124 and second ledge 126 allows modular housing component 200 to be received in device housing 102. Recess 128 in device housing 102 receives modular housing component 200. Recess 128 and housing component 200 are shaped to correspond to one another such that housing component 200 can be received in recess 128 with a snug fit in the space between first ledge 124 and second ledge 126. When housing component 200 is received in recess 128, exterior surface 214 of the housing component is aligned or flush with first exterior surface 114 of device housing 102.

[0067] 5 is a rear view of the isolated modular housing component 200. The housing component 200 comprises a removable panel or shell that covers a portion of the housing 102 in an installed position. The housing component 200 has a structure and shape that matches the device housing 102 in the area to be covered. In particular, the housing component 200 matches the shape of the exterior surface 116 and recess 128 to cover a portion of the device housing 102 in the installed position.

[0068] The housing component 200 includes a wall 202 having a first end 204 and a second end 206 extending therebetween to define a longitudinal axis Y of the housing component 200. When the housing component 200 is received in the device 102, the longitudinal axis Y of the housing component 200 is aligned parallel to the longitudinal direction X of the device 102. The wall 202 further includes a first edge 208 and a second edge 210 each extending longitudinally between the first end 204 and the second end 206. The wall 202 includes an interior surface 212 and an opposing exterior surface 214. The interior surface 212 and the exterior surface 214 each extend longitudinally from the first end 204 to the second end 206 and extend laterally from the first edge 208 to the second edge 210.

[0069] The interior surface 212 of the wall 202 is shaped to correspond and match the second exterior surface 116 of the device housing 102 so that the housing component 200 can be easily received on the second exterior surface 116. As such, the interior surface 212 of the wall 202 is curved or arcuate in a generally opposite or negative shape to the second exterior surface 116.

[0070] The curved interior surface 212 of the wall 202 forms a curved or arcuate surface. The interior surface 212 has a concave shape and defines a curved surface with an internal inflection point. The interior surface 212 is concave in a direction along the axis Y so as to form a convex longitudinal profile or convex shape when viewed along the axis Y of the housing component 200. The interior surface 212 forms a substantially complete arc shape and may have a generally constant curvature throughout the substantially complete arc shape.

[0071] The curved and concave shape of the inner surface 212 may be defined in terms of a center of curvature. The inner surface 212 faces toward the center of curvature and defines a concave shape. The inner surface 212 may extend approximately 180 degrees, or between 160 and 200 degrees, around the center of curvature to form a substantially complete arc.

[0072] The exterior surface 214 of the wall 202 is exposed to a user during normal use of the device and may therefore be shaped to conform to a user's grasp. As best seen in FIG. 3 , the exterior surface 214 comprises a generally convex shape similar to that of the third portion 122 of the first exterior surface 114 of the device housing 102. When the housing component 200 is attached to the device housing 102, the first exterior surface 114 of the device housing 102 and the exterior surface 214 of the housing component 200 provide a device exterior that is easily gripped or held.

[0073] The exterior surface 214 of the wall 202 forms a curved or arcuate surface. The exterior surface 214 has a convex shape and defines a curved surface with an exterior inflection point. The exterior surface 214 is convex in a direction along the axis X so as to form a convex longitudinal profile or convex shape when viewed in the direction of the axis X. The exterior surface 214 may form a substantially complete arc shape and may have a substantially constant curvature throughout the substantially complete arc shape.

[0074] The curved and convex shape of exterior surface 214 may be defined in terms of a center of curvature. Exterior surface 214 faces away from the center of curvature and defines a convex shape. Exterior surface 214 may extend approximately 180 degrees, or between 160 and 200 degrees, around the center of curvature to form a substantially complete arc.

[0075] In the illustrated example, the wall 202 of the housing component 200 has a substantially constant thickness between the interior surface 212 and the exterior surface 214. The thickness of the wall 202 is constant between the first edge 208 and the second edge 210. When the wall 202 has a constant thickness, the interior surface 212 and the exterior surface 214 have similarly shaped and aligned curved surfaces. Forming the housing component 200 with a substantially constant thickness provides a more structurally efficient shape that is robust and easily manufactured.

[0076] The device housing 102 and the housing component 200 may each have a substantially consistent longitudinal profile. That is, the cross-sectional shapes of the device housing 102 and the housing component 200 may be the same along substantially the entire length of each component. For example, the device housing 102 may have a substantially consistent longitudinal cross-sectional shape and size along between 10% and 90% of the length of the device housing 102 between the first end 106 and the second end 108. Additionally or alternatively, the housing component 200 may have a substantially consistent longitudinal cross-sectional shape and size along between 10% and 90% of the length of the housing component 200 between the first end 204 and the second end 206.

[0077] Alternatively, in an embodiment not shown, the housing component 200 may be formed such that the inner surface 212 is concave to match the second outer surface 116 of the device housing 102, while the outer surface 214 has a different shape or different features that may match the user's grip or provide an improved impression to the user.

[0078] The housing component 200 and the device housing 102 include respective attachment means for removably attaching the housing component 200 to the device housing 102. The attachment means of the illustrated embodiment can be best seen in Figures 6 and 7. Figure 6 shows the interior surface 212 of the housing component 200, which includes a plurality of elongated protrusions 216, 220 extending therefrom. Figure 7 shows the second exterior surface 116 of the device housing 102, which includes a plurality of elongated channels 130, 132 extending therefrom into the device housing 102.

[0079] The plurality of protrusions 216, 220 and the plurality of channels 130, 132 interact with one another to removably attach the housing component 200 to the device housing 102. A user may move the housing component 200 longitudinally relative to the device housing 102 to different longitudinal positions to attach and detach the housing component 200 from the device housing 102. Figures 8a-8c illustrate stages of attaching the housing component 200 to the device housing 102.

[0080] 8a shows the housing component 200 separated from the device housing 102. The housing component 200 moves in the direction indicated by arrow 1 onto the second exterior surface 116 of the device housing at a first longitudinal position. The protrusions of the housing component 200 are received in the channels of the device housing 102, and the housing component 200 is inserted into the device housing 102.

[0081] 8b shows housing component 200 being inserted into device housing 102 at a first longitudinal position. The housing component moves longitudinally along device housing axis X in the direction indicated by arrow 2 to a second longitudinal position. The protrusions of housing component 200 move in the same direction within the channels of device housing 102.

[0082] 8c shows the housing component attached and secured to the device housing 102 in a second longitudinal position. The protrusions may be secured within the channels in the second longitudinal position, as described in more detail below. To remove the housing component 200, the user may move the housing component 200 back to the first longitudinal position in the direction opposite to arrow 2, and then completely remove the housing component 200.

[0083] By providing multiple longitudinal protrusions and multiple channels, securing of housing component 200 to device housing 102 can be accomplished with a relatively small longitudinal movement (indicated by arrow 2). Housing component 200 is inserted onto second exterior surface 116 in a surface-facing direction before the small longitudinal movement locks housing component 200 in place.

[0084] This can provide a more robust attachment means and method than, for example, a single channel and protrusion extending along the entire length of the device housing and housing component. Smaller longitudinal locking movement means that manufacturing tolerance requirements for the channel and protrusion can be reduced. Smaller movement results in less chance of damage or deformation of the housing component or device housing. Also, the specific movement of the housing component onto the device housing can result in an improved user experience, for example, by providing an improved impression of robustness.

[0085] Returning to FIG. 6, the housing component 200 includes a first plurality of projections 216 extending from the interior surface 212 for attachment to a device housing as described above.

[0086] Each of the first plurality of protrusions 216 is elongated and longitudinally spaced apart from one another. The first plurality of protrusions 216 are aligned with one another along a line parallel to the longitudinal axis Y. Each of the protrusions 216 is elongated longitudinally along the housing component axis Y, such that a longitudinal dimension of the protrusion is greater than another dimension of the protrusion that is perpendicular to the longitudinal direction. In the illustrated embodiment, the first plurality of protrusions 216 includes three protrusions 216. The protrusions 216 have substantially the same longitudinal lengths as one another.

[0087] The protrusions 216 are separated longitudinally by gaps or spaces 218. The spaces 218 are areas defined between two protrusions 216 and the interior surface 212 that are free of any features of the housing component 200. The longitudinal extent of each space 218 may be greater than the longitudinal extent of one or both of the adjacent protrusions 216.

[0088] The housing component 200 can be attached to the device housing 102 as described above using only one of the longitudinally aligned projections 216. However, in the illustrated embodiment, the housing component 200 additionally includes a second projection 220 to further improve the robustness of the attachment to the device housing.

[0089] The second plurality of protrusions 220 are similar in shape and arrangement to the first plurality of protrusions 216, with similar corresponding longitudinal spacings 222. The second plurality of protrusions 220 are laterally spaced apart from the first plurality of protrusions 216, such that they are not aligned with the first plurality of protrusions 216. That is, each of the first plurality of protrusions 216 is separated from each of the second plurality of protrusions 220 in a direction perpendicular to the longitudinal axis Y, as indicated by arrow 3.

[0090] The second plurality of protrusions 220 may include the same number of protrusions as the first plurality of protrusions 216. For example, in the illustrated embodiment, the second plurality of protrusions 220 includes three protrusions. Each of the first plurality of protrusions 216 may substantially correspond to a respective one of the second plurality of protrusions 220 and have the same longitudinal position and longitudinal length as each of the other protrusions.

[0091] The second plurality of protrusions 220, spaced laterally from the first plurality of protrusions 216, provide attachment points between the housing component 200 and the device housing 102 that are spaced further apart across the second exterior surface 116, which may result in a more robust connection.

[0092] Returning to FIG. 7, the device housing 102 includes a first plurality of channels 130 configured to receive the first plurality of protrusions 216 to removably attach the housing component 200 to the device housing 102.

[0093] A first plurality of channels 130 are formed in the sidewall 110 of the device housing 102 through the second exterior surface 116. The channels 130 each extend partially through the sidewall 110 toward an interior space 112 bounded by the sidewall 110. In the illustrated embodiment, the channels 130 do not extend completely through the sidewall 110, but are separated from the interior space 112 by a portion of the sidewall 110.

[0094] Each of the channels 130 is elongated longitudinally along the device housing axis X, such that the longitudinal dimension of the channel is greater than the other dimension of the channel that is perpendicular to the longitudinal direction. The channels 130 are spaced apart longitudinally from one another. The channels 130 are aligned with one another along a line parallel to the longitudinal axis X.

[0095] The device housing 102 may additionally include a second plurality of channels 132 formed in the sidewall 110 through the second exterior surface 116 for receiving the second plurality of protrusions 220 of the housing component 200. The second plurality of channels 132 are similar in shape and arrangement to the first plurality of channels 130. The second plurality of channels 132 are laterally spaced apart from the first plurality of channels 130 and, as a result, are not aligned. That is, each of the first plurality of channels 130 is separated from each of the second plurality of channels 132 in a direction perpendicular to the longitudinal axis X, as indicated by arrow 4.

[0096] The second plurality of channels 132 may include the same number of channels as the first plurality of channels 130. For example, in the illustrated embodiment, the second plurality of channels 132 includes three channels. Each of the first plurality of channels 130 may substantially correspond to a respective one of the second plurality of channels 132 and have the same longitudinal position and longitudinal length as each of the other channels of the plurality of channels.

[0097] The first plurality of channels 130 may include a number of channels corresponding to the number of protrusions in the first plurality of protrusions 216. The second plurality of channels 132 may include a number of channels 132 corresponding to the number of protrusions in the second plurality of protrusions 220. For example, in the illustrated embodiment, the first plurality of channels 130 and the second plurality of channels 132 each include three channels. The channels 130, 132 receive each of the three protrusions in the first and second plurality of protrusions 216, 220, respectively.

[0098] The channels 130, 132 and protrusions 216, 220 may each include additional features, as described below, to improve the robustness of the attachment between the housing component 200 and the device housing 102 and the impression it provides to the user.

[0099] Figure 9 shows a detailed view of the housing component 200 and the features of the protrusions 216, 220. Figure 10 shows a view along section BB of Figure 9. The following features will only be described for one protrusion 216, but may be included on each of the protrusions 216, 220 in each plurality of protrusions. The features of the protrusions 220 of the second plurality are similar to the features of the protrusions 216 of the first plurality except that they are on opposite sides of the interior surface 212 of the housing component 200 and are mirror images or opposites.

[0100] Each of the protrusions 216 forms a shape with a first portion 224 and a second portion 226 and includes a first support surface 228 and a second support surface 230 for contacting a portion of the channel 130 to define a fit between the housing component 200 and the device housing 102.

[0101] The first portion 224 extends outward from the interior surface 212 to join the second portion 226. The second portion 226 extends from the junction with the first portion 224 to be separated from the interior surface 212 by the first portion 224. The first portion 224 and the second portion 226 cooperate to form a hook-like shape. The second portion and the first portion 224, 226 each have a longitudinally elongated shape. The first portion 224 extends laterally outward from the interior surface 212, and the second portion 226 extends laterally away from the first portion at an angle. In the illustrated embodiment, the first portion 224 forms an approximately right angle with the second portion 226 in a plane defined by the longitudinal axis Y.

[0102] The protrusions 216, 220 may be unitarily formed with the housing component 200 at the interior surface 212. Alternatively, the protrusions 216, 220 may be formed or partially formed and then permanently joined to the housing component 200 on the interior surface 212.

[0103] The protrusion 216 includes a first bearing surface 228a and a second bearing surface 230a that are formed at an angle to one another. The first bearing surface 228a and the second bearing surface 230a are configured to contact corresponding bearing surfaces that define the channel 130 when the housing component 200 is attached to the device housing 102. The bearing surfaces 228a, 230a may be formed as part of the second portion 226. The second bearing surface 230a forms an end of the second portion 228 remote from the junction to the first portion 224. The first bearing surface 228 forms a side of the second portion 226 that extends from the junction with the first portion 224 to the end of the second portion 226 remote from the junction.

[0104] Each of the bearing surfaces 228a, 230a is generally flat in the longitudinal direction. The bearing surfaces are disposed at an angle to one another. In the illustrated embodiment, the first bearing surface 228a forms an approximately perpendicular angle with the second bearing surface 230a in a plane defined by the longitudinal axis Y. The protrusion may include one or more chamfered corners 232, one of which separates the first bearing surface 228 from the second bearing surface 230 to improve the robustness of the protrusion 216 and its fit with the channels 130, 132. The chamfered corners 232 separate the protrusion from the sharp angled edges formed between the bearing surfaces of the channels 130.

[0105] As explained above, one protrusion 220 of the second plurality of protrusions may include first and second portions that are similar to first and second portions 224, 226 of first plurality of protrusions 216 except for having similar features and opposite or mirror image shapes. One protrusion 220 of the second plurality of protrusions may include first and second bearing surfaces 228b, 230b that are similar to first and second bearing surfaces 228a, 230a of protrusion 216.

[0106] The first bearing surfaces 228a, 228b of the first protrusion 216 and the second protrusion 220 may be arranged to face each other. The first bearing surfaces 228a, 228b that face each other comprise respective planar surfaces that define planes that intersect with each other at an acute angle. Alternatively, as in the illustrated embodiment, the first bearing surfaces 228a, 228b may be arranged to face directly toward each other. The first bearing surfaces 228a, 228b that face directly toward each other comprise respective planar surfaces that define non-intersecting planes.

[0107] By providing first support surfaces 228a, 228b facing towards each other, the two plurality of protrusions 216, 220 may form a gripping shape for retaining the protrusions 216, 220 within the channels 130, 132, as further described below.

[0108] The second bearing surfaces 230 a, 230 b of the first protrusion 216 and the second protrusion 220, respectively, may be arranged to face a common direction. In the illustrated embodiment, the second bearing surfaces 230 a, 230 b may be coplanar and may comprise respective planar surfaces that define a common plane.

[0109] By providing second support surfaces 230a, 230b facing a common direction, the two plurality of protrusions 216, 220 can abut against channels 130, 132 in a common direction to hold the housing component 200 a predetermined distance away from the device housing 102, as further described below.

[0110] The first and second plurality of channels 130, 132 include features for interacting with the first and second bearing surfaces 228a, 228b, 230a, 230b of the protrusions 216, 220.

[0111] Figure 11 shows a detailed view of the device housing 102 and the features of the channels 130, 132. Figure 12 shows a view along cross section CC of Figure 11. The following features will only be described for one channel 130, but may be included in each of the channels 130, 132 in each plurality of channels. The features of the second plurality of channels 132 are similar to the features of the first plurality of channels 130, except that they are on the opposite side of the second exterior surface 116 of the device housing 102 and are mirror images or opposite.

[0112] The channels 130 are defined in part by a first bearing surface 134 and a second bearing surface 136. Each of the first bearing surface 134 and second bearing surface 136 of the plurality of channels 130 is a planar surface formed by cutting into the sidewall 110 through the exterior surface 116. The bearing surfaces 134, 136 are generally flat along their longitudinal direction.

[0113] The first bearing surface 134a defines a first side 138 extending longitudinally of the channel 130, the first side 138 comprising an edge where the bearing surface 134 meets the convex second exterior surface 116. Similarly, the second bearing surface 136a defines a second side 140 extending longitudinally of the channel 130, the second side 140 comprising an edge where the bearing surface 136a meets the convex second exterior surface 116. The first bearing surface 134a and the second bearing surface 136a meet to define an edge 142 within the channel 130 that is recessed into the sidewall 110. The first bearing surface 134 and the second bearing surface 136 are disposed at an angle to each other at the edge 142. In the illustrated embodiment, the planes defined by the first bearing surface 134a and the second bearing surface 136a form a right angle with each other.

[0114] The second plurality of channels 132 may each include a first bearing surface 134b and a second bearing surface 136b that are similar to the bearing surfaces of the first plurality of channels 130 except that they have an opposite or mirror image shape.

[0115] The first support surfaces 134a, 134b of each of the first channel 130 and the second channel 132 may be arranged to face away from one another. The first support surfaces 134a, 134b that face away from one another comprise respective planar surfaces that define planes that intersect with one another at an acute angle. Alternatively, as in the illustrated embodiment, the first support surfaces 134a, 134b may be arranged to face away from one another directly. The first support surfaces 134a, 134b that face directly toward one another comprise respective planar surfaces that define non-intersecting planes.

[0116] The second bearing surfaces 136 a, 136 b of each of the first and second channels 130, 132 may be arranged to face a common direction. In the illustrated embodiment, the second bearing surfaces 136 a, 136 b may be coplanar and may comprise respective planar surfaces that define a common plane.

[0117] The housing component 200 is attached to the device housing 102 by inserting the protrusions 216, 220 into the respective channels 130, 132. Upon insertion, the first bearing surfaces 228a, 228b of the protrusions 216, 220 contact the first bearing surfaces 134a, 134b of the channels 130, 132. The protrusions 216, 220 are sized to have a configuration that fits within the channels 130, 132, such that the first bearing surfaces 228 of the protrusions generate a supporting force against the first bearing surfaces 134 of the channels 130, 132.

[0118] The form fit is established by positioning the first bearing surfaces 228a, 228b of the protrusions 216, 220 at a first separation distance and positioning the first bearing surfaces 134a, 134b of the channels 130, 132 at a second separation distance that is slightly greater than the first distance. The effect of this arrangement is that the protrusions 216, 218 must deform very slightly to be inserted into the channels 130, 132, generating a force. Because the first bearing surfaces 228a, 228b of the protrusions 216, 220 face inward toward each other, the force generated by the form fit urges these surfaces against the outward-facing first bearing surfaces 134a, 134b of the plurality of channels 130, 132.

[0119] The force between the respective support surfaces 228 and 134 creates a resultant frictional force that acts against, but does not completely impede, movement of the protrusions 216, 220 within the channels 130, 132. The friction occurs when a user inserts the housing component 200 into the device housing 102 and moves the housing component 200 longitudinally to an installed position.

[0120] Providing two pluralities of protrusions 216, 220 with first bearing surfaces 228 a, 228 b facing toward one another allows for setting a desired degree of friction fit of the housing component 200 to the device housing 102. The separation distance between the first bearing surfaces 228 of the first and second pluralities of protrusions 216, 218 can be reduced to increase frictional resistance, or the relative separation distance can be increased to decrease frictional resistance. The angled shapes of the first and second portions 224, 226 of the protrusions 216, 220 allow the desired separation of the first bearing surfaces 228 a, 228 b to be set independently of other factors by selecting the length of the first portions 224 of the protrusions 216, 220.

[0121] The second bearing surfaces 230a, 230b of the protrusions 216, 220 contact the second bearing surfaces 136a, 136b of the channels 130, 132 when the protrusions 216, 220 are fully inserted into the channels 130, 132. The second bearing surfaces 230a, 230b of the protrusions 216, 220 face a common direction substantially away from the housing component 200 and toward the device housing 102. The second bearing surfaces 136a, 136b of the channels 130, 132 face a common direction toward the second bearing surfaces 230 of the protrusions 216, 220.

[0122] Contact between the second bearing surfaces 230a, 230b of the protrusions 216, 220 and the second bearing surfaces 136a, 136b of the channels 130, 132 maintains separation of the housing component 200 from the device housing 102. In the inserted and attached positions, the housing component 200 is separated from the device housing 102 by a gap between the interior surface 212 of the housing component 200 and the second exterior surface 116 of the device housing 102.

[0123] By providing second support surfaces 230 facing the same direction, protrusions 216, 220 can be configured to set a desired gap between interior surface 212 and second exterior surface 116, for example, to account for manufacturing tolerances for irregularities that might otherwise impair the fit of housing component 200 to device housing 102. The angled shapes of first portion 224 and second portion 226 of protrusions 216, 220 allow the size of the desired gap to be set independently of other factors by selecting the length of second portion 226 of protrusions 216, 220. A longer second portion 226, for example, increases the gap between housing component 200 and device housing 102.

[0124] The two portions 226, 228 of the projections 216, 220 may be sized differently from one another to independently set the desired friction fit and component separation gap.

[0125] With continued reference to Figures 11 and 12, and with reference to Figures 8a-8c, channels 130, 132 may further include discontinuities or features formed in the otherwise planar first and second support surfaces 134a, 134b, 136a, 136b that may function to allow for more free insertion or removal of housing component 200 in a first longitudinal position of component 200 (as shown in Figure 8b), and to more fully secure component 200 to device housing 102 in a second longitudinal position (as shown in Figure 8c).

[0126] The features are described below with respect to one channel 130, but may apply to each channel 130, 132 of both the first and second pluralities of channels. The channel 130 may include a first tab or lip 144 formed in the first bearing surface 134a. The first lip 144 extends away from the first bearing surface 134a at a side 138 of the channel 130 where the first bearing surface 134a meets the second exterior surface 116. The first lip 144 includes a convex exterior surface that is continuous with the second exterior surface 116, forming a partial arcuate profile.

[0127] First lip 144 is formed by the area of ​​sidewall 110 that is not cut away to form channel 130, thereby creating a discontinuity in the otherwise planar first bearing surface 134a of channel 130. The discontinuity in first bearing surface 134a allows protrusion 216 to be secured or released from channel 130 depending on the position of protrusion 216.

[0128] The first edge 144 extends only partway along the longitudinal length of the first support surface 134, and thus the first support surface 134a comprises a portion of the planar surface adjacent the first edge 144 and, together with the second support surface 136, extends completely from the side 138 up to the edge 142.

[0129] During insertion of the housing component 200 into the device housing 102, the protrusion 216 can be received within the channel 130 at this planar portion adjacent the first lip 144 by sliding laterally across the first support surface 134a and approaching or contacting the second support surface 136a.

[0130] The first edge 144 also extends only partway across the first support surface 134 from the side 138 towards the edge 142 between the support surface 134 and the support surface 136, so that the first support surface 134 has a portion of a planar surface between the first edge 144 and the edge 142 with the second support surface 136.

[0131] During a subsequent step of longitudinally moving the housing component 200 to the second position, the protrusion 216 moves longitudinally along the axis X into this portion of the planar surface 134a so that it is received within the channel 130 between the first lip 144 and the second bearing surface 136a. The protrusion 216 is held between the first lip 144, the second bearing surface 136a, and the end of the channel 130. This prevents the protrusion 216 and the attached component 200 from moving in any direction except longitudinally back to the first position. The housing component 200 may subsequently be removed by moving the component 200 to the first longitudinal position where the protrusions 216, 220 are not secured.

[0132] The first lip 144 thereby provides a locking means for securing the housing component 200 to the device housing 102 depending on the longitudinal position of the housing component 200 .

[0133] The channels 130, 132 may further include second and third edges 146, respectively, formed on a side 140 of the channel 130 where the second support surface 136 meets the second exterior surface 116. The second and third edges 146 are formed by areas of the sidewall 110 that are cut off by the channels 130, 132 below the second exterior surface 116. The edges 146 each extend partially across the channel 130 from the side 140. The edges 146 are separated longitudinally. The edges 146 form covering portions of the channel 130 in which the projections are received at first and second longitudinal locations.

[0134] 9, the housing component 200 may further include an embossment 234 formed by a raised area of ​​the interior surface 212, which may act as a "stop" feature for movement of the housing component 200. The embossment 234 may have a generally oval or racetrack peripheral shape. Referring to FIG. 9, the device housing 102 includes a corresponding recess 148 formed in the side wall 110 through the second exterior surface 116 and having a corresponding oval or racetrack peripheral shape.

[0135] The embossed portion 234 is aligned with the recessed portion 148 when the housing component 200 is in an installed position on the device housing 102, such that the embossed portion 234 fits within the recessed portion 148. When the housing component 200 is not installed, for example, when it is being moved into position by a user, the embossed portion 234 may abut the exterior surface 116.

[0136] As explained above, when housing component 200 is moved to the attached position, embossment 234 moves from abutting exterior surface 116 into recess 148, creating a click and noise in housing component 200 that can be felt by the user, providing tactile feedback and an impression of solidity to the user. When embossment 234 is within recess 148, a small resistance to movement of housing component 200 is created, giving the user the impression of a stationary point through tactile feedback.

[0137] As described above, the device housing 102 may be manufactured in a single piece or by attaching separate components. The housing 102 may be formed in whole or in part in a single piece by injection molding and then further processed to form the channels 130, 132. The channels 130, 132 may be formed by cutting or routing through the sidewall 110 of the device housing 102. The shapes of the channels 130, 132 described above are easily formed by cutting or routing, resulting in relatively easy and reliable manufacturing of the device housing 102. In particular, the alignment planar support surfaces 134, 136 and the protruding ridges 144 and lips 146 that are part of the sidewall 110 are easily formed by cutting or routing into the sidewall 110.

[0138] The cutting or routing can be performed by computer numerically controlled (CNC) machining, allowing the channels to be entirely formed by cutting or routing in an automated process that can be easily and reliably repeated to create multiple device housings with the same features.

[0139] As explained above, the housing component 200 may also be manufactured in a single piece or by attaching separate pieces. Injection molding may be used to form the housing component 200 and the protrusions 216, 220 in a single piece. Machining may then be used to form the features of the housing component 200, including the molding of the protrusions 216, 220.

[0140] While exemplary embodiments have been described, those of ordinary skill in the art will recognize that certain modifications would come within the scope of the present disclosure. For that reason, the following claims should be studied to determine the scope and content of the present disclosure.
