Abstract

An electronic device includes a backplane including a set of slots configured to receive user-removable modules; a printed circuit board, coupled to the backplane; and a set of interface blocks, electrically connected to the printed circuit board, that enable power and data transfer between modules coupled to the set of interface blocks.

First claim

We claim:

1. A modular smartphone comprising:
a backplane comprising a metal housing, a battery layer and a printed circuit board; wherein the metal housing includes a set of slots configured to receive user-removable modules; wherein the metal housing includes a set of rails configured to form the set of slots;
a set of interface blocks, electrically coupled to the printed circuit board, positioned within one or more of the set of slots, that enable power transfer and data transfer between modules coupled to the set of interface blocks; wherein power transfer and data transfer between modules occur via the printed circuit board; and
a network communication switch, located on and electrically coupled to the printed circuit board, that mediates data transfer between modules coupled to the set of interface blocks.

2. The smartphone of claim 1 , wherein the set of rails comprises a spine extending along the length of the metal housing and a set of ribs positioned perpendicular to the spine and extending from the spine to a perimeter of the backplane.

3. The smartphone of claim 2 , further comprising a front backplane configured to receive a display module.

4. The smartphone of claim 3 , wherein the set of slots and the set of rails are arranged according to a rectangular grid and the set of slots is configured to receive modules corresponding to integer multiples of a unit cell size of the rectangular grid.

5. An electronic device comprising:
a backplane including a set of slots configured to receive user-removable modules;
a set of rails defining the set of slots, wherein the set of rails comprises a spine extending along the length of a metal housing and a set of ribs positioned perpendicular to the spine and extending from the spine to a perimeter of the backplane, wherein the spine comprises a set of metal inserts, each metal insert of the set of metal inserts positioned within a slot of the set of slots, wherein the set of metal inserts is configured to retain modules inserted in the set of slots via magnetic force;
a printed circuit board, coupled to the backplane; and
a set of interface blocks, electrically connected to the printed circuit board, that enable power and data transfer between modules coupled to the set of interface blocks.

6. The device of claim 5 , wherein an interface block of the set of interface blocks includes a power contact, configured to enable power transfer between a module coupled to the interface block and the printed circuit board, and a data interface, configured to enable data transfer between the module and the printed circuit board.

7. The device of claim 6 , wherein the power contact comprises power pins and the data interface comprises capacitive pads.

8. The device of claim 5 , wherein the printed circuit board comprises a network switch that enables direct communication between modules coupled to the set of interface blocks.

9. The device of claim 8 , wherein the network switch is a packet switch.

10. The device of claim 8 , wherein data transfer between a first module coupled to the network switch and a second module coupled to the network switch is initiated by the first module and completed without using a host or an intermediate module.

11. The device of claim 5 , wherein the spine comprises a set of electropermanent magnet.

12. The device of claim 5 , further comprising first and second modules electrically coupled to the printed circuit board; wherein the first module comprises a battery and provides power to the second module via the printed circuit board.

13. An electronic device comprising:
a backplane including a set of slots configured to receive user-removable modules;
a set of rails defining the set of slots, wherein the set of rails comprises a spine extending along the length of a housing and a set of ribs positioned perpendicular to the spine and extending from the spine to a perimeter of the backplane, wherein the spine comprises a set of electropermanent magnets, each electropermanent magnet of the set of electropermanent magnets positioned within a slot of the set of slots; wherein the set of electropermanent magnets is configured to retain modules inserted in the set of slots via magnetic force;
a printed circuit board, coupled to the backplane; and
a set of interface blocks, electrically connected to the printed circuit board, that enable power and data transfer between modules coupled to the set of interface blocks.

14. The device of claim 13 , wherein an interface block of the set of interface blocks includes a power contact, configured to enable power transfer between a module coupled to the interface block and the printed circuit board, and a data interface, configured to enable data transfer between the module and the printed circuit board.

15. The device of claim 14 , wherein the power contact comprises power pins and the data interface comprises capacitive pads.

16. The device of claim 13 , wherein the printed circuit board comprises a network switch that enables direct communication between modules coupled to the set of interface blocks.

17. The device of claim 16 , wherein the network switch is a packet switch.

18. The device of claim 16 , wherein data transfer between a first module coupled to the network switch and a second module coupled to the network switch is initiated by the first module and completed without using a host or an intermediate module.

19. The device of claim 13 , wherein the spine comprises a set of metal inserts.

20. The device of claim 13 , thither comprising first and second modules electrically coupled to the printed circuit board, wherein the first module comprises a battery and provides power to the second module via the printed circuit board.
