Abstract

An improved housing for a computing device is disclosed. The improved housing can have one or more of the following aspects. One aspect of the invention pertains to a computing device provided with an internal antenna. One aspect of the invention pertains to a stiffener for a computer housing so as to increase the rigidity and strength of the computer housing. One aspect of the invention pertains to a lid for a computing device, such as a portable computer, that is provided with a translucent housing.

Claims

1. A portable computing device, comprising:

a housing comprising a first member and a second member, wherein the first member is coupled to the second member to form a substantially enclosed cavity within which various functional electronic components of the portable computing device are positioned, the functional electronic components having a total volume that is substantially less than the volume of the substantially enclosed cavity such that the substantially enclosed cavity includes an unused void around the functional electronic components; and

a stiffener disposed within and substantially filling the unused void, the stiffener increasing a strength and rigidity of the housing by distributing external loads more evenly across the housing, wherein the stiffener is adjacent to the first and second members and is configured to conform to internal features of the housing adjacent to the stiffener.

2. The portable computing device as recited in claim 1, wherein various function electronic components are connected with the first member.

3. The portable computing device as recited in claim 1, wherein the stiffener is formed of foam.

4. The portable computing device as recited in claim 3, wherein the foam is packaging foam.

5. The portable computing device as recited in claim 3, wherein the foam is formed from a material selected from the group consisting essentially of:

polyurethane, expanded polystyrene, expanded polypropylene and expanded polyethylene.

6. The portable computing device as recited in claim 3, wherein the foam stiffener is machined, molded or die cut to a desired prefabricated geometry.

7. The portable computing device as recited in claim 1, wherein inner surfaces of the housing have a complex geometry, and wherein the stiffener has an outer geometry that coincides with an inner geometry of at least portions of the housing.

8. The portable computing device as recited in claim 7, wherein the stiffener further includes protrusions and depressions for filling empty spaces between inner surfaces of the housing.

9. The portable computing device as recited in claim 1, wherein the stiffener further includes a stiffener cavity.

10. The portable computing device as recited in claim 9, wherein the stiffener cavity is configured to provide clearance for functional electronic components of the portable computing device.

11. The portable computing device as recited in claim 9, wherein the stiffener cavity is a weight reduction cavity.

12. The portable computing device as recited in claim 1, wherein at least portions of the housing are thin and flexible.

13. The portable computing device as recited in claim 1, wherein the functional components include an antenna, the antenna being configured to transmit or receive RF signals, the housing being configured to enclose the antenna such that the antenna is entirely contained internal to the housing and is operable while being internal to the housing without having to extend any portion of the antenna outside the housing.

14. The portable computing device as recited in claim 1, wherein the portable computing device is a portable computer including a base and a lid, the lid being coupled to the base via a hinge, and wherein the housing corresponds to the housing of the lid or the housing of the base.

15. The portable computing device as recited in claim 1, wherein the stiffener is fastened within the housing via a lip.

16. The portable computing device as recited in claim 1, wherein the stiffener is structurally coupled to at least a portion of the housing via an adhesive.

17. The portable computing device as recited in claim 1, wherein portions of the housing and the stiffener form a laminate structure which provides resistance to point pressure loading.

18. A portable computing device, comprising:

a housing that forms a substantially enclosed cavity within which various functional electronic components of the portable computing device are positioned, the functional electronic components having a total volume that is substantially less than the volume of the substantially enclosed cavity such that the substantially enclosed cavity includes an unused void around the functional electronic components; and

a stiffener disposed within and substantially filling the void, the stiffener increasing a strength and rigidity of the housing by distributing external loads more evenly across the housing, wherein the functional electronic components include at least a flat panel display and wherein the flat panel display emits light in a forward direction and in a back direction when active; and

wherein a first member of the housing forms a back of the housing and includes a transparent portion through which a portion of the light emitted by said flat panel display in the back direction is able to pass, thereby illuminating the transparent portion when said flat panel display is active, the stiffener including an opening for allowing light to pass therethrough.

19. The portable computing device as recited in claim 18, wherein the stiffener is formed of foam.

20. The portable computing device as recited in claim 18, wherein the stiffener is configured to provide clearance for functional electronic components of the portable computing device.

21. A portable computing device, comprising:

a housing that forms a substantially enclosed cavity;

electronic components of the portable computing device within the substantially enclosed cavity, wherein the substantially enclosed cavity includes an unused volume around the electronic components; and

a stiffener disposed within the substantially enclosed cavity and substantially filling the unused volume, wherein at least a portion of the stiffener extends from a front side of the housing to a back side of the housing, wherein the stiffener is configured to conform to internal features of the housing adjacent to the stiffener, and wherein the stiffener is configured to distribute external loads more evenly across the housing.

22. The portable computing device of claim 21, wherein the stiffener comprises foam.

23. The portable computing device of claim 21, wherein the stiffener includes protrusions and depressions for filling empty spaces between inner surfaces of the housing.
