Vehicle Cranks TRIZ Cases
- Bicycle Pedal Polymer-Metal Platform Segmentation
Segmenting the pedal body and combining polymer grip sections with metal plates resolves strength versus comfort trade-offs.
- Cycling Shoe Fixing Device Automatic Release via Brake Sensing
A cycling shoe fixing device uses a brake sensing module to automatically release shoes from pedals.
- Extendable Bicycle Cranks With Eccentric Telescopic Mechanism
Telescopic crank arms extend and retract via an eccentric mechanism to optimize force application without complex gears.
- Bicycle Front Sprocket Axial Movement for Multi-Sprocket Chain Alignment
Axial movement of the front sprocket compensates for increased axial length in eleven-plus rear sprocket assemblies, maintaining driving efficiency.
- Tri-Power Exerciser Integrating Linear Core Motion Into Rotational Torque
Tri-power exerciser converts linear core sliding into rotational torque via inverted racks, enabling simultaneous upper and lower body engagement.
- Bicycle Bottom Bracket Hanger Water Ingress Sealing
Nested tubular hangers with internal O-rings prevent water ingress into the bearing assembly, reducing maintenance needs and extending component reliability.
- Adjustable Crank Arm With Notched Retention Block
Notched crank arms lock via cam-driven blocks to eliminate vibration and play during rehabilitation adjustments.
- Bicycle Crank Arm Assembly Sprocket Twisting Prevention
Crank arm elements contact front sprocket sides to block twisting deformation, enhancing motion transmission efficiency.
- Pivoting Foot Platform Decouples Drive Arm Angle for Elliptical Trainers
Segmenting the foot platform via a pivot mechanism allows independent angular adjustment, reducing frame size while preventing extreme foot angles.
- Bottom Bracket Generator for Wireless Sensor Power
An integrated electrical generator converts bottom bracket shaft rotation into electricity, eliminating battery replacement and wiring complexity.
- Curved Drum Pedal with Self-Locking Tension Adjustment
A curved drum pedal design enhances foot comfort and dexterity during extended playing sessions.
- Non-Visual Pedaling Balance Feedback via Audio and Haptic Cues
A controller processes left-right crank arm data to generate non-visual notification commands for auditory or tactile feedback.
- Cycling Crank Casing Protrusion for Pedaling Measurement
A cycling crank casing uses a protrusion to connect signal processing circuitry with spindle measurement electronics.
- Bicycle Shoe Sole with Variable Groove Width for Pedal Engagement
Variable groove width accommodates foot rotation during pedaling, resolving the trade-off between secure engagement and comfortable operation feeling.
- Bicycle Pedal Signal Detection Device Power Supply Inversion
Inverting power placement to stationary pedal body simplifies structure and extends battery life for bicycle signal detection devices.
- Pedal Coupling Unit With Pivoting Cleat Release Mechanism
Segmenting the coupling unit into pivotable members eliminates complex twisting motions required for cleat disengagement.
- Exercise Bicycle Planar Four-Bar Linkage Seat Dynamics
A planar four-bar linkage moves the seat with translation and rotation.
