Last week Patently Mobile posted a patent report titled "Samsung Working on Dual Device Charging Pad that will work with both Magnetic Inductive and Resonant Methods." Today's report is based on a granted patent issued to Samsung late this month that illustrates another wireless charger idea. It's the charging device toaster. You slide in your device, it's lowered to align the wireless charging components and when it's full charged it pops up signifying to the user its done.
Granted Patent: The Wireless Charging Toaster
Samsung's granted patent covers an invention relating to a wireless battery charger.
Samsung's patent FIG. 6 is a perspective view of a second example of the wireless charger: FIG. 8A is a cross-sectional view of the second example cradling a mobile phone for charging; FIGS. 11 is a schematic illustrating one of the possible arrangements for minimizing standby power consumption of the wireless charger.
Technically, Samsung notes in their summary that "A general aspect of the disclosed examples provides a wireless charger that optimizes charging efficiency in the charging of portable terminals (mobile phones, or the like) of various sizes. In general, such a wireless charger includes a housing with an insertion hole through which a portable terminal can be inserted, and a transmitting coil in the housing disposed to face a receiving coil of an inserted portable terminal. A pair of laterally spaced side supports in the housing are disposed to move laterally toward and away from each other on opposite sides of an inserted portable terminal, while a bottom support in the housing is disposed to move lengthwise of the housing and support a portion of the bottom of an inserted portable terminal. The side supports are mechanically linked to the bottom support such that movement of the bottom support is coordinated with movement of the side supports.
One or more elastic members may be interposed between the housing and any one or more of the side and bottom supports to provide a return force for the supports after the portable terminal is removed from the housing.
According to another aspect, the bottom support may comprise two separate bottom support portions, each connected to a separate side support to form two support assemblies; and movement of each support assembly may be guided by a guide protrusion slidably engaged with a guide rail inclined with respect to the side supports and the bottom support.
The gradient of the guide rail may substantially correspond to an aspect ratio of an insertable portable terminal.
According to yet another aspect, a power transfer unit including gears coordinates movement of the bottom support and at least one of the side supports.
The power transfer unit may have a first gear that meshes with teeth on the bottom of a side support and is rotated by lateral movement of the side support; and a second gear that meshes with the first gear and with teeth on the bottom support to move the bottom support lengthwise of the housing."
Samsung's recently granted patent was originally filed in the U.S. in Q4 2015.
Samsung was also granted a design patent earlier this month for a next-gen headset design as noted below.
