Railway Tunnels TRIZ Cases
- Rail-Guided Electromagnetic Flying Vehicle With Compressed-Air Propulsion
Compressed-air thrust and rail-guided electromagnetic lift cut drag, energy use, and maglev maintenance complexity.
- Contactless Vehicle Trajectory Control Through Tubular Switches
Electromagnetic guidance keeps a suspended vehicle at safe lateral distances through tubular switches, enabling smooth high-speed direction changes.
- Containerized Parcel Switching Track for Low-Cost Last-Mile Routing
Independent side wheel assemblies guide containerized parcel vehicles through track bifurcations, cutting last-mile energy use and delivery cost.
