Vehicle Cranks TRIZ Cases
- Split-type footrest
See how a split-type footrest uses snapping parts and hanging arm lugs to enable detachable ass
- A cycling cleat and a cycling pedal
See how a releasably mountable resilient member in a cycling cleat regulates bias and float to
- Bicycle Pedal Battery Case With Integrated Wire-Free Contacts
Integrated conductive holders and insulating layers replace wires in a bicycle pedal battery case, improving vibration reliability and battery replacement.
- Sprocket Bearing Dust Cover With Impeller for Dirt Deflection
A radially extended dust cover and impeller keep dirt out of sprocket bearings while avoiding the friction penalty of fully sealed bearings.
- Bicycle Power Spindle Layout for Compact Sealed Measurement
A spindle-integrated battery chamber, gauge, and circuit shrink bicycle power meters while shielding signals and components from water and dust.
- Bicycle Pedal Pin Generator for Battery-Free Power Measurement
Pedaling drives a generator inside the pedal pin to power deformation sensing without batteries, charging connectors, or exposed hardware.
- Sensor-Based Bicycle Light Modules for Pedal Orientation Sensing
Position and motion sensing let pedal-mounted light modules switch forward or rearward output automatically while conserving battery power.
- Elastic Terminal Assembly for Bicycle Electrical Contact Reliability
A deformable terminal member maintains stable PCB-to-device contact while cutting assembly parts and adding static protection.
