Thus far Patently Apple has covered about 14 patents covering wireless charging in one form or another and all could be reviewed in our special archive. The patent filing hints of a coming solution for desktops as well. Whether the desktop solution will be ready for 2017 iMac isn't known yet but wireless charging solutions from an alliance of players are allegedly being prepared to launch next year, so I can't see Apple far behind.
In 2013 Patently Apple posted a report titled "The Cordless Home is now in Reach with Magnetic Resonance" In that report we pointed to a Company called Rezence. The photo above was an example of wireless charging being built into a home's countertop. This is the type of solution that Apple's patent application revealed today.
The reason for the delay in this technology coming to market was that there were two very powerful competing standards that could have hurt the industry if the market was badly split. Think Betamax vs VHS. Engadget reported last year that the two companies had reportedly merged and time was needed to iron out a single powerful standard.
So the timing of this patent filing coming public helps us to see that Apple is preparing for wireless charging solutions across the board. You can't have Apple Store product tables with embedded wireless charging if you don't have products with it built-in. Duh. Its very admission would tell you that a host of products with wireless charging built-in are around the corner.
Wireless Charging Station
Apple's patent FIG. 1 noted below illustrates an exemplary wireless charging station #100 which includes a charging surface #102. The charging surface may be a surface upon which a device having a receiver may rest to wirelessly charge its battery.
In other embodiments, the charging surface may include curvature such that regions of the charging surface are substantially non-planar. The curvature may be convex or concave, or may include multiple convex and concave profiles organized in a predetermined or random arrangement.
Apple's patent FIG. 10 noted above is a simplified diagram illustrating a charging surface configured to selectively energize certain transmitters closest to an electronic device
Apple's patent FIG. 7B noted below is a simplified diagram illustrating a receiver including coils having bow tie-shaped loop portions and a shielding disk disposed above the coils
Future Apple Store Product Table / Charging Table
Apple's patent FIG. 5 noted below illustrates a side-view cross-sectional perspective of a future Apple Store product tablet noted here as "charging structure" #500 that includes an upper charging surface 502 and a transmitter 504 having a plurality of transmitting coils 504a-504d.
With reference to a three-dimensional space, Z and X directions of magnetic fields are observable in FIG. 5, while magnetic fields in the Y direction, although existing in the embodiment of FIG. 5, are not shown for ease of description. In some embodiments, the table can be located in a retail environment and used to display and charge multiple electronic devices for potential purchase.
Alternative Design for a Desktop
Apple notes that although the charging structure shown in patent FIG. 5 is that of a table having a charging surface #502 supported by a plurality of legs, it is to be appreciated that the charging structure can be any structure having a charging surface upon which an electronic device may be placed. For example, in other embodiments, the charging structure can be a charging mat that is sized and shaped for personal use (e.g., to be placed on a desktop or similar surface).
For all of the finer invention details about the coils and so forth could be found in a pair of Apple's patent applications revealed today that were filed just this past June. Considering that this is a patent application, the timing of such a product to market is unknown at this time.
