Abstract

A mobile electronic device (100), suitable for operation in a first configuration and a second configuration, includes a first housing (102) and a second housing (104) coupled to the first housing. The second housing includes a rotatable keypad (202). The rotatable keypad rotates when the first housing (102) and the second housing (104) are changed from a first configuration to a second configuration.

Claims

1. An mobile electronic device suitable for operation in a first configuration and a second configuration, the mobile electronic device comprising:

a first housing moveable between a first configuration position and a second configuration position; and

a second housing coupled to the first housing, the second housing comprising a rotatable keypad, wherein the rotatable keypad is mechanically coupled to the first housing such that the rotatable keypad rotates when the mobile electronic device is switched from the first configuration to the second configuration.

2. The mobile electronic device according to claim 1 wherein the first housing is offset from the second housing in one direction in the first configuration and offset from the second housing in another direction in the second configuration.

3. The mobile electronic device according to claim 1 wherein the rotatable keypad rotates when the mobile electronic device is switched from the second configuration to the first configuration.

4. The mobile electronic device according to claim 1 wherein the first housing comprises a display unit.

5. The mobile electronic device according to claim 1 wherein the first housing comprises external keys.

6. The mobile electronic device according to claim 5 wherein the external keys are navigation keys.

7. The mobile electronic device according to claim 5 wherein the external keys are implemented virtually.

8. The mobile electronic device according to claim 1 wherein the second housing further comprises a set of keys.

9. The mobile electronic device according to claim 1 wherein the first housing comprises a slot, the slot facilitating rotation of the rotatable keypad by guiding movement of a first pin in the slot, the first pin being located on the rotatable keypad.

10. The mobile electronic device according to claim 1 further comprising a link mechanism, the link mechanism comprising:

a first link coupled to the first housing;

an elbow joint couple to the first link; and

a second link coupled to the elbow joint and the rotatable keypad,

wherein the link mechanism facilitates rotation of the rotatable keypad.

11. The mobile electronic device according to claim 1 further comprising one or more magnets.

12. The mobile electronic device according to claim 1 further comprising one or more sensors.

13. The mobile electronic device according to claim 1 further comprising a stepper motor, the stepper motor facilitating rotation of the rotatable keypad.

14. The mobile electronic device according to claim 1 further comprising a groove for allowing a second pin to move inside the groove, the groove being located on one of the first housing and the second housing, and the second pin being located on another of the first housing and the second housing, the second pin preventing the mobile electronic device from operating in the first configuration and the second configuration simultaneously.

15. The mobile electronic device according to claim 1 further comprising a dual slide mechanism, the dual slide mechanism comprising:

one or more bushings; and

one or more rods for sliding within the one or more bushings,

wherein the dual slide mechanism facilitates switching of the mobile electronic device between the first configuration and the second configuration.

16. The mobile electronic device according to claim 1 further comprising a flexible circuit wherein the flexible circuit provides electrical connections between the first housing and the second housing.

17. The mobile electronic device according to claim 1 wherein the rotatable keypad comprises at least 12 keys.

18. A portable electronic device comprising:

a first housing moveable between a most compact configuration position and a less compact configuration position; and

a second housing coupled to the first housing, the second housing comprising a rotatable keypad that is mechanically coupled to the first housing such that the rotatable keypad rotates when the first housing is moved to the less compact configuration position from the most compact configuration position.

19. The portable electronic device according to claim 18 wherein the first housing comprises a display.

20. The portable electronic device according to claim 19 wherein the display changes orientation when the first housing is moved to the less compact configuration position from the most compact configuration position.
