Wheel Based Transmission TRIZ Cases
- Adjustable Ride-On Toy Seatback With Multi-Position Snap Mounting
Resilient snaps and hooks let a ride-on toy seatback lock into multiple hole sets, fitting different child sizes without a complex mechanism.
- One-Piece Plastic Vehicle Seat for Multi-Activity Mobility
A hollow one-piece plastic seat with integrated rear conduits cuts vehicle cost while supporting ergonomic, multi-activity mobility.
- Motorcycle Oil Pump Control for Transmission and Clutch Protection
ECU-driven motor rotation primes a mechanical oil pump in neutral or clutch-off states to prevent startup oil starvation in the transmission and clutch.
- Electric Scooter Output Gear With Spline Fit for Stable Wheel Torque
A spline-fitted output gear transfers reduced torque directly to the wheel, reducing clearance errors and stabilizing electric scooter rotation.
- Cycle Gear Motor Bearing Layout for Self-Centering Torque Balance
Deformable rolling elements let a cycle gear motor shaft self-center under load, reducing torque imbalance, noise, and vibration.
- Hub Drive Structure With Coaxial Gear Set for Low Jitter Noise
An internal hood fixes the stator to the hub shaft and aligns the gear set coaxially to boost starting force, cut kinetic loss, and reduce jitter noise.
- Bicycle Wheel Hub Gear Train for Low-Tension Motor-Assisted Shifting
A fixed-ratio hub gear train separates torque paths to keep chain tension low, enabling smoother motor-assisted shifting and less wear.
- Mid-Drive Gearbox With One-Way Bearings for Isolated Power Paths
One-way bearings isolate pedal and motor power paths in a mid-drive gearbox, cutting friction losses and preventing pedal interference.
