Abstract

A portable device having improved configurability and adaptability. The portable device has a case or chassis that can be placed in either an open or closed position, to thereby allow for insertion and removal of other devices within the portable device. When increased functionality is required or desired, the device'"'"'s case is expanded by placing it in an open position, to allow additional devices to be operated in conjunction with the portable device. These devices can provide various types of electronic or computer operations, such as electronic adapters or media drives, as well as mechanical operations such as air movement with one or more additional fans or other types of heat sink. When decreased functionality is required or desired, such as to reduce the overall size and weight of the portable device, the device'"'"'s case is contracted by placing it in a closed position. This allows on-demand expansion and contraction capability for the portable device. The expandable case provides dual functionality by also providing improved cooling for the portable device when in an open position.

Claims

1. A portable electronic device, comprising:

a hinged cover that is operable to open and close, wherein when open, an expansion bay is accessible by a user to add at last one fan to the portable electronic device, wherein the fan is moveable to a retracted position when the cover is closed, and moveable to an extended position when the cover is open.

2. The portable electronic device of claim 1, wherein the fan is coupled to the cover by a lockable hinge to allow the fan to be raised, lowered and locked into position.

3. A portable electronic device, comprising:

a hinged cover that is operable to open and close, wherein when open, an expansion bay is accessible by a user to add at least one fan to the portable electronic device, wherein the hinged cover is a bottom cover of the electronic device.

4. A portable electronic device, comprising:

a chassis; and

a cover that is fixedly attached to the chassis, and is operable to lock in an open position and lock in a closed position, wherein when locked in the open position at least one expansion bay is user accessible to add at least one fan to the portable electronic device, wherein the fan is moveable to a retracted position when the cover is in the closed position, and moveable to an extended position when the cover is in the open position.

5. The portable electronic device of claim 4, the fan is coupled to the cover by a lockable hinge to allow the fan to be raised, lowered and locked into position.

6. A portable electronic device, comprising:

a chassis; and

a cover that is fixedly attached to the chassis, and is operable to lock in an open position and lock in a closed position, wherein when locked in the open position at least one expansion bay is user accessible to add at least one fan to the portable electronic device, wherein the cover is a bottom cover of the electronic device.

7. A portable electronic device, comprising:

a chassis; and

a cover that is fixedly attached to the chassis, and is operable to lock in an open position and lock in a closed position, wherein when locked in the open position at least one expansion bay is user accessible to add at least one fan to the portable electronic device, wherein the expansion bay collapses from an extended position when the cover is positioned to the closed position.

8. A portable electronic device, comprising:

a chassis; and

a cover that is fixedly attached to the chassis, and is operable to lock in an open position and lock in a closed position, wherein when locked in the open position at least one expansion bay is user accessible to add at least one fan to the portable electronic device, wherein the expansion bay extends from a collapsed position when the cover is positioned to the open position.

9. A method of operating a portable electronic device, comprising the steps of:

unlatching a bottom cover of the portable electronic device;

opening the unlatched bottom cover;

latching the unlatched bottom cover in an open position, wherein the bottom cover has a plurality of sides, and at least two of the plurality of sides is hingedly attached to the portable electronic device, and the step of opening the unlatched bottom cover comprises a step of rotating the bottom cover about one of the at least two hingedly attached sides; and

adding an additional device to the portable electronic device through the open position.

10. A housing for a portable electronic devices, comprising:

a top surface;

a perpendicular side around the perimeter of the top surface, wherein the perpendicular side has a height to physically accommodate internal components;

an expandable bottom surface at least partially within the height of the perpendicular side when in a collapsed position, and at least partially outside the height of the perpendicular side when in an expanded position to enable addition of at least one heat dissipating device by a user; and

at least one additional internal component coupled to the expandable bottom surface.

11. The housing of claim 10, further comprising a latching mechanism to latch the expandable bottom surface when in the collapsed position.

12. The housing of claim 10, further comprising a latching mechanism to latch the expandable bottom surface when in the expanded position.

13. A housing for a portable electronic device, comprising:

a top surface;

a perpendicular side around the perimeter of the top surface, wherein the perpendicular side has a height to physically accommodate internal components;

an expandable bottom surface at least partially within the height of the perpendicular side when in a collapsed position, and at least partially outside the height of the perpendicular side when in an expanded position; and

a latching mechanism that provides both (i) rotational movement of the expandable bottom surface to provide partial expansion of the portable electronic device and (ii) linear movement of the expandable bottom surface to provide full expansion of the portable electronic device.
