Vehicle Cranks TRIZ Cases
- Bicycle Crank Assembly Axial Sprocket Support
Rolling members reduce sliding resistance between the support portion and sliding portion, preventing chain derailment while maintaining high radial strength.
- Bicycle Crank Power Measurement with Inner Surface Strain Gauges
Inner surface strain gauges protect sensors from physical damage while maintaining high bending sensitivity.
- Crankset Power Measurement via Spider Strain Sensing
Spider-mounted strain sensors measure crankset torque directly, isolating cyclist effort from drive line losses and external factors.
- Combined-Drive Bicycle Handle Mechanism for Independent Power Transmission
A combined-drive bicycle handle assembly generates motive force through a crank mechanism while steering the front wheel.
- Bicycle Motor Unit Segmented Housing for Compact Installation
Segmented bicycle motor housing fits through frame openings to reduce orthogonal size while enabling easy installation and removal.
- Pedal Locking Mechanism with Plunger and Cuff for Secure Retention
A pedal system uses a plunger to lock or release rotation relative to a drive shaft while a cuff retains the user's foot.
- Piezoelectric Sensor Material for Bicycle Components
A piezoelectric material with optimized ferroelectric particle ratios generates electric power from mechanical strain in bicycle components.
- E-bike Bottom Bracket Bearing Torque Measurement
Magnetic triggers on a torsion element detect deformation time differences, resolving shaft sensor misalignment errors in e-bikes.
