Electric Power TRIZ Cases
- Resonant Wireless Charging for Electric Toothbrushes
Segmented charging transmitters enable flexible device placement and simultaneous multi-device charging while maintaining high efficiency.
- Contactless Power Supply Foreign Object Detection via Weighted Feedback
Weighted feedback signals in a contactless power supply detect foreign objects and coil shifts, preventing overheating without temperature sensors.
- Battery Charger Preventing Lithium Plating via Anode Potential Control
A battery charger adjusts charging current based on calculated anode resistance and voltage to prevent lithium plating during fast charge cycles.
- Vertical Wireless Charger Foreign Object Detection via Thermal Sensing
A vertical wireless charger uses a bottom thermal sensor to detect metal foreign objects generating unusual heat during charging.
- Software Thermal Charging Regulation for Cellular Phones
A software controlled thermal feedback system dynamically adjusts charging power levels in portable devices.
- Wireless Power Receiver Antenna Reconfiguration
A wireless power receiver dynamically adjusts antenna configurations to optimize signal reception.
