Vehicle Cranks TRIZ Cases
- Bicycle Pedal Integrating Strain Gauge in Pedal-Pin
A bicycle pedal embeds an electronic measurement circuit within the pedal-pin to detect mechanical deformation via strain gauges.
- Exercise Device with Pivot Shaft for Knee Joint Protection
A pivot shaft within 20 cm of the pelvis redirects force from knees to thighs, reducing joint stress during leg exercises.
- Pivoting Crank Arm Mechanism for Eliminating Pedal Dead Zones
Dynamic pivot arms eliminate top and bottom dead zones by maintaining continuous torque application during hill climbing.
- Bicycle Pedal Integrated Cable Lock Mechanism
Integrating a retractable cable lock into the pedal body eliminates carrying separate hardware while securing both wheels and frame against theft.
- Bicycle Pedal Cleat Jaw Retention Mechanism
A bicycle pedal jaw retained in the open position by a dedicated stop means, preventing untimely deactivation during cleat alignment.
- Cleat Base Assembly Blind Alignment via Conical Guides
Conical guides on a cleat and pedal base assembly create a volumetric engagement zone that enables blind alignment without precise rider positioning.
- Alternating Bicycle Drive with Spiral Spring Rope Biasing
Spiral springs bias traction ropes in alternating bicycle drives, reducing frame twisting loads and preventing rope breakage.
