Rail Devices TRIZ Cases
- Wireless Ground Power Diagnosis Across Multiple Charging Conditions
Multiple charging conditions reveal parameter shifts that improve abnormality diagnosis accuracy for wireless ground power supply devices.
- Pantograph Control Using Catenary Detection for Safe Power Switching
Onboard cameras and microprocessor control raise or lower the pantograph from catenary detection to avoid wire damage and battery drain.
- Wireless Charging DC-DC Converter Mode Switching for EV Power Loss
Switching a vehicle DC-DC converter between active and on-state bypass modes cuts wireless charging loss while keeping power supply stable.
- External Power Connector Layout for Safe Vehicle Maintenance Charging
A protected external DC connector lets a moving body receive maintenance power without dangerous capacitor discharge into the supply.
- Multi-Voltage Electrical Architecture for Charging Machines in Motion
Dual AC/DC and DC/DC buses let battery-powered machines charge while moving or stationary, balancing high transfer rates with compliance.
