Electric Power TRIZ Cases
- Wireless Power Phase Control Using Backscatter Feedback
Backscatter feedback lets the transmitter optimize RF phase for higher received power without power-hungry wireless synchronization.
- Vehicle Battery Interrupter Using a Wedged Ball Disconnect
A spring-loaded conductive ball breaks and locks out the battery circuit after a collision, preventing false trips and post-crash fire risk.
- Vehicle Battery Isolation for Abnormal ECU Current Drain
A switched vehicle power layout isolates abnormal ECU current drain while keeping communications active for user alerts.
- USB-PD Controller for Wireless Charging Power Coordination
A unified USB-PD controller directly adjusts adapter voltage and wireless charging power to cut latency, regulators, and overload risk.
- Ambient Power Transmission Scheduling for Collision-Free Uplinks
A mediator-based scheduler coordinates charging and uplink timing for ambient power devices to cut collisions and improve throughput.
- Dynamic Impedance Matching for Wireless Power Reception
Dynamic impedance matching adapts RF and load conditions to cut reflections and improve wireless power delivery to DC loads.
- Charging Control Circuit Layout for Battery Heat Isolation
Separated transformer modules and an intermediate stage improve heat dissipation, lowering cell temperature in compact portable chargers.
- Welding Power Supply Interlock for High-to-Low Voltage Isolation
An auxiliary switch and dual contactors block welding voltage from reaching the battery charge output, preventing high-voltage damage.
- Battery Passport Distribution Module for Secure Data Transparency
Distributed battery passport access uses blockchain and fraud detection to improve lifecycle transparency without centralizing sensitive data.
- Digital Battery Passport Module for Lifecycle Data Traceability
A modular digital battery passport records composition, sustainability, and performance data to improve lifecycle traceability and access.
- NFC-Latched Load Disconnect Circuit for Safe Wireless Power
An NFC-powered relay latch couples a wireless appliance only when connected, preventing hazardous induction power transfer.
- Battery Passport Supervision Module for Fraud Detection and Traceability
Centralized supervision of digital battery passports improves lifecycle data transparency with performance evaluation, fraud detection, and traceability.
