WIRELESS POWER TRANSMISSION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17867016 titled 'WIRELESS POWER TRANSMISSION APPARATUS
Simplified Explanation
The abstract describes a wireless power transmission apparatus that includes an upper housing, a lower housing, and a substrate. It also includes a transmit coil, at least one temperature sensor, and a flexible printed circuit board (FPCB).
- The transmit coil is wound in a rotating form on the substrate, between the upper and lower housing.
- The temperature sensor includes a pattern resistor, which has a resistance value that changes with temperature.
- The temperature sensor is placed on the FPCB, which is a flexible circuit board.
- The pattern resistor is wound in a specific pattern on the FPCB, starting from one point and winding around the central portion of the FPCB before rewinding in the opposite direction.
Potential applications of this technology:
- Wireless charging systems for electronic devices such as smartphones, tablets, and wearables.
- Power transmission for electric vehicles, eliminating the need for physical charging cables.
- Industrial applications where wireless power transmission can be used for automation and machinery.
Problems solved by this technology:
- Enables wireless power transmission, eliminating the need for physical connections and cables.
- Provides a temperature sensor to monitor the heat generated during power transmission, ensuring safe and efficient operation.
Benefits of this technology:
- Convenience and ease of use, as devices can be charged without the need for physical connections.
- Improved safety by monitoring and controlling the temperature during power transmission.
- Potential for increased efficiency in power transmission, reducing energy loss.
Original Abstract Submitted
A wireless power transmission apparatus is provided. The wireless power transmission apparatus includes an upper housing, a lower housing coupled to the upper housing, a substrate disposed between the upper housing and the lower housing, a transmit coil disposed between the upper housing and the substrate and formed by being wound in the form of rotating on the substrate, at least one temperature sensor including a pattern resistor, a resistance numerical value which varies with temperature, and a flexible printed circuit board (FPCB) on which the at least one temperature sensor is disposed. The pattern resistor is disposed on the FPCB in a pattern of being wound in a first direction from any first point on the FPCB to any second point different from the any first point on the FPCB around a central portion of the FPCB and being rewound in a second direction opposite to the first direction.
