## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This document claims the benefit of the filing date of U.S. Provisional Patent Application 61/756,872, entitled “Device and Assembly for Attaching External Optical Components to a Portable Electronic Device” to Bednarik, which was filed on Jan. 25, 2013, the contents of which are hereby incorporated by reference.


BACKGROUND
1. Technical Field
Aspects of this document relate generally to a device and an assembly for coupling external optical components to a portable electronic device such as a cell phone.
2. Background Art
The portable media player market has changed dramatically in the past several years and with it, the portable media player case market. Recent trends have focused on the emergence of the mobile media device, which simply put is a handheld phone incorporating several additional features not found in traditional handheld phones.
Mobile media devices can include one or more of the following features: the merging of a personal data/digital assistant (PDA) and a cellular phone; a keyboard interface (e.g., a QWERTY keyboard) configuration as either a touch screen or tactile keyboard; the capability to receive/download audio/video files. Furthermore, mobile media devices can: run an operating system software providing a standardized interface and platform for application developers; include advanced features like e-mail, Internet access and e-book reader capability; and/or include a built-in full keyboard or external USB keyboard and VGA connector. Mobile media devices can also include sophisticated multimedia functionality such as audio/video recording and playback capabilities previously only available in specific devices such as cameras, video cameras, and video players.
In other words, a mobile media device can be considered a miniature computer that has telephone capability and one or more multimedia capabilities that were previously reserved to many specific individual devices. Examples of mobile media devices include: the iPhone® product by Apple Inc. of Cupertino, Calif., the Blackberry® product by Research In Motion (RIM) of Waterloo, Ontario, Canada, and the Android® devices produced by Nokia of Keilaniemi, Espoo, Finland, LG Corp. of Seoul, South Korea and Samsung Group of Seoul, South Korea.
Photographic and videographic devices have also undergone significant changes in recent years. Digital cameras are widely available and even simple entry-level cameras often have video recording capabilities. Since the introduction of mobile phones, and later, mobile media devices that incorporated built-in cameras with video recording capabilities, the trend has focused on integrating what once were point-specific devices into robust multimedia platforms, as evidenced by the dominance of multimedia as one of several synergistic features offered by recent mobile media devices. Technological advances have made all but the most advanced digital cameras and camcorders obsolete. Many mobile media devices offer built-in cameras that exceed, by an order of magnitude, functionality that was only available in high-end specialty equipment only a generation earlier.
All of these devices have benefited from the breadth and depth of technological advances, ranging from miniaturization of electrical and electronic components, to the increasing power and efficiency of microprocessors, to large quantities of digital storage. In short, capabilities and market adoption are increasing while cost and physical size are decreasing—a steady improvement in the price-to-performance ratio as a consequence of diffusion into the global marketplace.
Following the introduction of mobile media devices, mobile media device cases were introduced. Cases are intended to provide physical protection for mobile media devices and the ability for users to more easily handle and use a mobile media device. They can also provide various types of aesthetic qualities. In some instances, cases offer a simple mechanical function that provides better usability or convenience.
The nexus of these developments and trends represents the current state-of-the-art. Mobile media devices are essentially handheld, highly portable multimedia-capable computers. It is now possible to take photos, record video, compose correspondence, and communicate it in near real-time over the Internet, all by using the same mobile media device.
Mobile media devices and their cases serve complementary though largely unrelated functions. The case is merely an accessory that provides a few simple features such as protecting the surfaces of the mobile media device, or providing a different surface material to enhance ergonomics usability, or providing aesthetic benefits.
Unfortunately, current mobile media device cases have many shortcomings. Some attempts have been made to create entire mobile media device cases with a fixed optics assembly, but none have the ability to use interchangeable optics assemblies that couple to, and remove from, the mobile media device case without additional tools. The current state-of-the-art either does not offer this feature or requires the user to have in his possession multiple cases, such that he must use a specific case for a specific function such as attaching a microscope to enhance the built-in camera's optical capabilities. Requiring the user to have multiple cases is not only costly, but is both impractical and inefficient. A mobile media device case having fixed optics, such as a microscope, is undesirable because the user cannot easily stow this case on his person and he must have another case when he wishes to afford the benefits of a case without the additional functionality

As shall be shown and described in greater detail hereafter, the optical component coupling may removably couple to the portable electronic device case via a tongue and groove arrangement or some other type of attachment geometry arrangement.
FIGS. 1-3 depict various views of a non-limiting embodiment of an assembly for coupling an external optical component to a portable electronic device. FIG. 1 depicts a front perspective view of a portable electronic device case 1, an optical component coupling 2, and an optical component 3. FIG. 2 depicts a rear perspective view of a portable electronic device case 1, an optical component coupling 2, and an optical component 3. FIG. 3 depicts a side perspective view of a portable electronic device case 1, an optical component coupling 2, and an optical component 3.
In one or more embodiments of assembly for coupling an external optical component 3 to a portable electronic device, the portable electronic device case 1 comprises a rear wall 8 comprising an inner surface 15 and an outer surface 10. The portable electronic device case 1 further comprises two opposing sidewalls 7 coupled to the rear wall 8. The two opposing sidewalls 7 are positioned on portable electronic device case 1 to hold the portable electronic device between the two opposing sidewalls 7. When a portable electronic device is coupled to the portable electronic device case 1, the rear surface of the portable electronic device is typically positioned adjacent the inner surface 15 of the rear wall 8.
The rear wall 8 further comprises a camera opening 4 extending through the rear wall 8 and positioned to align with the camera and/or flash component of the portable electronic device when the portable electronic device case 1 is coupled thereto. Accordingly, the rear wall 1 does not cover the camera and/or flash component of the portable electronic device when the portable electronic device 1 is coupled to the portable electronic device. As depicted in the non-limiting figures of FIGS. 2 and 3, the portable electronic device case 1 may further comprise a cord port slot 17, a volume button slot 16, and a top slot opposite the cord port slot 17. In one or more embodiments, the sidewalls 7 of the portable electronic device case 1 may at least partially extend over the top and/or bottom of the portable electronic device case 1 to prevent the portable electronic device from sliding out of the portable electronic device case 1.
One or more embodiments of a portable electronic device case 1 further comprise at least one rear groove 5 on the outer surface 10 of the rear wall and at least one side groove 9 on an outer surface 14 of at least one sidewall 7 of the two opposing sidewalls 7. In the particular non-limiting embodiment depicted in FIGS. 1-3, the portable electronic device case 1 comprises three rear grooves 5 on the rear wall 8 and one side groove 9 on the side wall 7 nearest the camera opening 4. Although not required in all embodiments, the camera opening 4 may be positioned between two rear grooves 5.
The one or more rear grooves 5 of the portable electronic device case 1 are sized to allow the one or more rear tongues 14 (shown in FIGS. 2 and 3) of the optical component coupling 2 to slide within the one or more rear grooves 5 when removably coupling the optical component coupling 2 to the portable electronic device case 1. The one or more rear grooves 5 are likewise sized to engage with the one or more rear tongues 14 when the optical component coupling 2 is coupled to the portable electronic device case 1 and, in combination with the engagement of the side groove 9 and side tongue 19, prevent the optical component coupling 2 from uncoupling from the portable electronic device case 1.
The one or more side grooves 9 of the portable electronic device case 1 are sized to allow the one or more side tongues 19 (shown in FIG. 3) of the optical component coupling 2 to slide within the one or more side grooves 9 when removably coupling the optical component coupling 2 to the portable electronic device case 1. The one or more side grooves 9 are likewise sized to engage with the one or more side tongues 19 when the optical component coupling 2 is coupled to the portable electronic device case 1 and, in combination with the engagement of the rear grooves 5 and rear tongues 14, prevent the optical component coupling 2 from uncoupling from the portable electronic device case 1.
One or more embodiments of an optical component coupling 2 comprise a face plate 12 and a side plate 11 coupled to or integral with one another. The optical component coupling 2 is typically sized such that the face plate 12 is adjacent the outer surface 10 of the rear wall 8 of the portable electronic device case 1 and the side plate 11 is adjacent the outer surface 14 of the sidewall 7 of the portable electronic device case 1 when the optical component coupling 2 is coupled to the portable electronic device case 1.
As briefly noted above, the optical component coupling 2 typically comprises one or more rear tongues 14 and one or more side tongues 19. The one or more rear tongues 14 are positioned on an inner surface 18 of the face plate 12 to align with and slidably couple to one or more rear grooves 5 of the portable electronic device case 1. The one or more rear tongues 14 are sized to fit within the one or more rear grooves 5 of the portable electronic device case 1. In the particular non-limiting embodiment depicted in FIGS. 1-3, the optical component coupling 2 comprises two rear tongues 14 positioned to align and engage with the two rear grooves 5 adjacent the camera opening 4. In other embodiments, only a single rear tongue 14 is required.
The optical component coupling 2 typically comprises one or more side tongues 19. The one or more side tongues 19 are positioned on an inner surface of the side plate 11 to align with and slidably couple to one or more side grooves 9 of the portable electronic device case 1. The one or more side tongues 19 are sized to fit within the one or more side grooves 9 of the portable electronic device case 1. In the particular non-limiting embodiment depicted in FIGS. 1-3, the optical component coupling 2 comprises two side tongues 19. A first of the two side tongues 19 is positioned to engage with the one side groove 19, and a second of the two side tongues 19 is positioned to engage with the side wall 7 opposite the rear wall 8. In other embodiments, only a single side tongue 9 is required.
One or more embodiments of an optical component coupling 2 comprise a shoulder 20. The shoulder 20 is typically positioned on the inner surfaces of the optical component 2 to abut the top of the portable electronic device case 1 when the optical component coupling 2 is coupled to the portable electronic device case 1 and the optical component opening 100 is aligned with the camera opening 4. In abutting the top of the rear wall 8 and/or sidewall 7, the shoulder 20 prevents the optical component opening 100 and the optical component 3 from sliding past the camera opening 4. Thus, the shoulder 20 assisting in the proper alignment of the optical component 3 with the camera of the portable electronic device.
As just referenced, embodiments of the optical component coupling 2 typically comprise an optical component opening 100. The optical component opening 100 is positioned to align with the camera opening 4 when the optical component coupling 2 is removably coupled to the portable electronic device case 1. The optical component opening 100 is likewise positioned to align with the camera of the portable electronic device when the optical component coupling 2 and the portable electronic device are removably coupled to the portable electronic device case 1. In one or more embodiments, the optical component coupling 2 further comprises an optical component coupling mount 6 protruding from an outer surface 13 of the face plate 12. The optical component opening 100 typically extends through the optical coupling mount 6. The optical coupling mount 6 is configured to securely mount or couple the optical component 3 to the optical component coupling 2.
The optical component 3 may comprise any of optical components previously referenced. In some embodiments, the optical component 3 is removably coupled to the optical component mount 6 of the optical component coupling 2, thus allowing for interchanging of the various type of optical components to the optical component coupling 2. In other embodiments, the optical component 3 is fixedly coupled to the optical component coupling 2 and/or the optical component mount 6. Coupling of the optical component 3 to the optical component coupling 2 may be accomplished the any of a number of mechanisms known in the art, such as but not limited to adhesives, friction, threaded coupling, snap fits, and the like.
In operation of coupling the optical component coupling 2 with the portable electronic device case 1 of an assembly for coupling an external optical component 3 to a portable electronic device, one or more rear tongues 14 are aligned with one or more rear grooves 5 and one or more side tongues 19 are aligned with one or more side grooves 9. The optical component coupling 2 is then slid onto the portable electronic device case 1 until the shoulder 20 abuts the portable electronic device case 1, the one or more rear tongues 14 being engaged with the one or more rear grooves 5 and the one or more side tongues 19 being engaged with the one or more side grooves 9. When the shoulder 20 abuts the portable electronic device case 1, the optical component opening 100, and optical component 3 if present, are aligned with the camera opening 4 of the portable electronic device case 1.
FIGS. 26 and 27 depict a more detailed view of a non-limiting example of an optical component coupling 2.

Various implementations may be manufactured using conventional procedures as added to and improved upon through the procedures described here. Some components may be manufactured simultaneously and integrally joined with one another, while other components may be purchased pre-manufactured or manufactured separately and then assembled with the integral components.
Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, routing, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components.
In places where the description above refers to particular implementations of an assembly, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other assemblies. The accompanying claims are intended to cover such modifications as would fall within the true spirit and scope of the disclosure set forth in this document. The presently disclosed implementations are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than the foregoing description. All changes that come within the meaning of and range of equivalency of the claims are intended to be embraced therein.
