Propulsion Using Ac Induction Motors TRIZ Cases
- Electric Assist Bicycle Control Using Acceleration-Based Power Adjustment
Acceleration and torque sensing let the bike adapt motor assist to slopes and headwinds without manual mode switching.
- Railway Traction Converter Using Brake Chopper Rectification
Shared brake chopper rectification lets a railway drive handle single-phase and three-phase power without extra rectifiers, saving space.
- Contactless Power Inter-Floor Transport for High-Rise Access
A contactless guide cable powers an aerial vehicle in one passage, enabling high-floor access, easier maintenance, and multiple boarding units.
- Overhead Contact Wire Layout for Automatic Pantograph Disconnection
Laterally diverging contact wires trigger controlled pantograph lowering and load-break switching to avoid arcing in restricted road sections.
