Direction Of Current Indication TRIZ Cases
- Battery Orientation Polarity Detection Circuit
A polarity-sensing circuit detects battery insertion orientation to switch operational modes, resolving power polarization issues without mechanical switches.
- Capacitive Voltage Indicator for Power Cord Detection
A capacitive voltage indicator detects AC potential on insulated power cords using a non-contact sensor and human ground path.
- Parallel Energy Accumulator Polarity Comparison Fault Detection
Comparing polarity of electrical measurands across parallel energy accumulators identifies faulty units for isolation without disrupting system operation.
- Trailer Brake Flyback Diode Protection via MOSFET Blocking
A blocking MOSFET in series with a flyback diode prevents reverse polarity damage in trailer brake modules.
