Electric Propulsion TRIZ Cases
- Vacuum Capsule Maglev Bogie Layout for Low-Drag High-Speed Travel
A bogie-mounted maglev layout combines linear synchronous propulsion, lateral guidance, and hybrid levitation to cut drag and energy use in vacuum capsules.
- Pantograph Head Energy Harvesting for Isolated Low-Voltage Power
Transducers harvest pantograph head oscillations to deliver isolated low-voltage power for onboard monitoring without transformers or batteries.
- Integrated Pantograph End Horn With Insulated Insert for Arcing Control
A non-metallic insert supports a tubular pantograph end horn to improve conductor alignment, reduce arcing, and limit line damage.
- Pantograph Field Detection for Overhead Line Presence Control
Magnetic or electric field sensing detects overhead supply presence before pantograph lifting, helping prevent unintended collector deflection.
- Rotating Electromagnetic Field Generator for Mass Propulsion
Dynamic switching of electromagnetic field generators creates high-strength spinning poly-phased fields that efficiently lift and propel mass.
