Vehicle Cranks TRIZ Cases
- Quick-Mount Crank-Pedal Mechanism for Children Bicycles
A quick-mount crank-pedal mechanism integrates the rod and pedal into a single unit for tool-free assembly on children bicycles.
- Bicycle Crank Seal with Differential Chainring Motion
A seal ring fits onto the crank arm using retention lips and a slot tab to mate with arm grooves, ensuring a complete seal between the crank arm and chainring.
- Pedaling Force Measurement Device Using Segmented Strain Sensors
Segmented strain sensors suppress parameter interference in a pedaling force measurement device, improving detection precision.
- Bicycle Pedal Pawl Extension Prevents Cleat Recoil
Curved pawl extension prevents cleat recoil during engagement, enhancing pedal stability without adding complex separate stop mechanisms.
- Bicycle Power Meter Dual Pedal Data Aggregation
Dual measurement units calculate pedal force and transmit data for combined power output.
- Bicycle Crank Assembly Axial Offset for Wider Tires
A bicycle crank assembly positions the sprocket transverse to the axle to prevent chain contact with the chain stay.
- Bicycle Pedal Pin Internal Chambers for Sensor Protection
Internal chambers in the pedal pin protect sensors from impact damage while maintaining structural integrity.
- Crank Arm Power Meter Self-Calibration via Zero Offset
A crank arm power meter calculates a zero offset value to update power logic for accurate readings.
- Cycling Shoe Wedge Alignment for Kinetic Chain Integrity
Wedge inserts compensate for biomechanical malalignments in the kinetic chain, reducing overuse injury risk during power application.
- Bicycle Crankset Cam Preload Mechanism
A bicycle crankset uses a cam member to move a washer along the spindle axis for precise bearing preload.
- Interchangeable Bicycle Pedal Body with Anti-Slip Coupling Plate
A bicycle pedal body uses interchangeable stepping assemblies and a coupling plate to enhance traction.
- Self-Centering Dual-Axis Bicycle Pedal
Rotatable pedal housing reduces knee strain by allowing lateral foot movement while springs return the device to a resting position.
- Magnetic Engagement Mechanism for Bicycle Pedal
A bicycle pedal uses rotating magnetic platters to secure a ferrous cleat through rotational alignment.
- Bicycle Shoe Cleat with Dual-Surface Design for Pedal Compatibility
A bicycle shoe cleat features dual engaging members and adjustable slots to connect racing footwear with mountain bike pedals.
- Bicycle Crankset Asymmetric Bore Torque Adjustment
Offset connecting bore generates adjustable torque output without increasing assembly complexity.
- Bicycle Pedal Heel Triangle Reduces Metatarsal Stress
A bicycle pedal assembly with a protruding heel triangle alters foot contact points to improve cycling comfort.
- Drive Assembly with Dual Cranksets for Compact Elliptical Motion
Dual cranksets segment the elliptical motion into shorter arms, reducing device size while maintaining natural running kinematics without long guides.
- Bicycle Container Pedal Engagement Stand
A bicycle container uses a detachable engagement member to couple with the pedal for stable support.
- Bicycle Bottom Bracket with Identical Roller Bearings
Identical roller bearings in the bottom bracket resolve durability trade-offs while integrated sensors enable precise torque detection.
- Bicycle Dual Power Propulsion with Turning Track
Dual power propulsion system uses yoke-connected forearm bars to drive a crank axle via rack and pinion gears.
- Bicycle Shim Keying and Curved Screw for Cleat Stability
Interlocking shims and curved screws prevent interface slippage while maintaining precise cleat angle settings.
