Rider Propulsion TRIZ Cases
- Removable Spindle Assembly for Snow Vehicle Ski Maintenance
Segmented spindle assembly couples ski to steering frame via removable interfaces, resolving maintenance difficulty under high impact loads.
- Motorized Bicycle Drive with Unidirectional Power Transmission
Unidirectional transmission modules decouple motor and pedal power, eliminating frame modifications for standard bicycle installation.
- Snowmobile Tunnel Resilient Rear Bendable Impact Absorption
A snowmobile tunnel rear section bends downward under impact and returns to its original shape using a resilient material segment.
- Pedal Drive Clearance Detection for Ghost Pedaling Prevention
Spring return devices detect idle positions in pedal drive clearances, preventing ghost pedaling and self-pedaling without complex sensors.
- Reciprocating Handlebar Bicycle Front Wheel Drive Linkage
A bicycle front wheel drive mechanism uses a two-arm and three-arm linkage system to convert reciprocal handlebar movement into rotational power.
- Electric Bicycle Motor Mounting Assembly with Adapting Pieces
Adapting pieces connect motor units to lateral covers and frames, resolving stability issues from heavy loads while enabling universal compatibility.
- Segmented Chain Guard for Electric Bicycle Motor Housing
A segmented chain guard mounts to an electric bicycle motor housing using parallel lateral sections and a peripheral gap to accommodate the drive chain.
- Vehicular Drive System On-the-Fly Mode Switching
A control unit monitors speed ratio and drive request signals to enable FWD-only operation without stopping the vehicle.
