Wheel Adhesion TRIZ Cases
- Accumulator-Fed Water Injection for Vehicle Anti-Aquaplaning
Pressurized accumulators and targeted wheel-path injectors cut pump bulk, weight, and power while enabling rapid anti-aquaplaning response.
- Magnetic Wheel Flux Switching for Secure Grip and Release
A motor rotates annular discs to vary magnetic flux, giving metallic wheels strong adhesion for stability and lower release force when needed.
- Self-Feeding Traction Strip for Vehicle Recovery on Ice
Wheel rotation pulls a tapered traction strip under the tire, improving single-person vehicle recovery on ice and other low-friction surfaces.
- Anti-Aquaplaning Liquid Injection Using Pre-Pressurized Accumulators
Pre-pressurized fluid accumulators enable fast anti-aquaplaning injection ahead of the tires without heavy high-power hydraulic pumps.
- Vehicle-Mounted Sand Ladder Release for Rapid Off-Road Traction
A vehicle-mounted sand ladder uses a track and activatable release to deploy under the wheels quickly, cutting manual effort in soft terrain.
- Recovery Board Inner Valley Structure for Tire Traction
Raised outer gripping rows and a lowered inner valley improve tire engagement on loose soil or snow, reducing slippage during vehicle recovery.
- Dual-Layer Recovery Board for Lightweight Traction Durability
A metallic inner core with a flexible traction layer helps recovery boards stay light, resist wheel heat, and grip uneven ground.
- Movable Sand Discharge Opening for Wheel-Rail Contact
A movable discharge opening places sand at the wheel-rail contact point during sanding, then retracts to limit splash exposure and sand waste.
