Multiple Wheel Assembly TRIZ Cases
- Dual-Wheel Obstacle-Crossing Mechanism With Low Friction Loss
A smaller driving wheel compresses a larger contact wheel to bridge obstacles while keeping friction loss low for efficient daily walking.
- Segmented Rolling Wheel Structure for Curved Surface Adhesion
Segmented annular rolling elements tilt and translate to keep contact area and magnetic adhesion on curved or uneven surfaces.
- Expandable Spare Wheel Hub Fastening for Jack-Free Installation
A nested inner-thread hub and central hex screw speed spare wheel installation without a jack while reducing hub size and machining time.
