Cycle Control Systems TRIZ Cases
- Bicycle Propelling Device Using Hand Grip Levers
Hand grip levers pull strings connected to a free wheel, resolving balance instability caused by arm-powered propulsion.
- Power Supply Controller for Human-Powered Vehicle Communication
A power supply controller manages electric power sources to optimize energy consumption and communication efficiency in human-powered vehicles.
- Bicycle Brake Lever Cap Off-Center Foot Design
Off-center foot portion distributes impact force over a larger area to prevent impalement without interfering with handlebar operation.
- Inverted Pendulum Vehicle Steering via Seat Weight Shift
A dynamically stabilized vehicle uses a tiltable seat to transfer lateral weight shifts into steering commands through a central pivot mechanism.
- Vehicle Accelerator Grip Reaction Force Control
Adjusts accelerator grip reaction force via motor control to provide tactile feedback, resolving stability-drivability trade-offs during cornering.
- Bicycle Brake Lever Wireless Signal Transmission
A bicycle brake lever actuates an electrical switch to generate an electric signal for wireless transmission.
- Synchronous Stem and Handle Folding Mechanism for Electric Scooters
Integrated driving mechanisms synchronize stem telescoping and handle folding to eliminate separate manual operations, improving user convenience.
- Bicycle Hydraulic Component Sealing with Misalignment Tolerance
A bicycle hydraulic component uses a stepped bore and fluid stopper to seal passages without precise alignment.
- Pole Propelled Velocipede Lower Body Steering
A two-wheeled vehicle uses handheld poles for propulsion and a saddle interface for steering.
- Bicycle Control Device Gear Indicator Mechanism
A bicycle control device integrates a second gear with indicia to visually display current gear positions on the handlebar.
- Self-Locating Controls via Capacitive Hand Tracking
Capacitive sensor arrays detect hand position and orientation to adapt control locations dynamically.
- Bicycle Brake Master Cylinder with Bladder and Retainer
A bicycle brake master cylinder uses a bladder and retainer to manage fluid volume during piston movement.
- Bicycle Hydraulic Lever Integrating Reservoir and Cylinder
Integrating the reservoir tank and cylinder bore into a single base member reduces assembly complexity while maintaining hydraulic pressure generation.
- Adjustable Switch Base for Human-Powered Vehicle
A pivotally coupled switch base adjusts position relative to a vehicle structure, resolving complexity trade-offs in user-operated controls.
- Bicycle Control Device Short Shifting Action
A bicycle control device uses a pivoting wire takeup member to shift gears.
- Bicycle Operating Device With Magnetic Return
A coaxial bicycle operating device uses magnetic cooperation to bias an operating ring back to a display position.
- Bicycle Hydraulic Brake Lever Ergonomic Protuberance Design
A bicycle manual control device features a support body protuberance and specific hydraulic cylinder angle for secure hand grip.
- Bicycle Lever Wireless Switch Base Mount
Placing the electrical switch on the base member simplifies lever structures while enabling wireless operation of electrical components.
- Motorcycle Switch Unit Light Shielding Film Design
A motorcycle switch unit uses a transmissive portion with an outer light shielding film to direct LED illumination toward operation marks.
