Cycle Control Systems TRIZ Cases
- Collapsible Control Lever Device for Motorcycle Impact Protection
Segmented transmission isolates hydraulic components from crash forces, protecting the piston and simplifying post-fall maintenance.
- Bicycle Shift Controller With Independent Levers
A bicycle shift controller uses two independent levers to rotate a cable take up member for intuitive gear changes.
- Bicycle Brake Lever Reach Adjustment via Threaded Cam Mechanism
A bicycle brake lever adjusts its reach position using a threaded connection and cam surface interaction for precise rider alignment.
- Bicycle Control Device with Integrated Suspension and Gear Shifting
A bicycle control device integrates suspension and gear shifting functions into a single unit mounted on the handlebar.
- Bicycle Hydraulic Reservoir with Transparent Inspection Portion
Segmented base member and transparent resin tank allow direct visual inspection of hydraulic fluid flow without disassembly.
- Bicycle Take-Up Device for Independent Cable Control
A take-up device moves control cables to manage bicycle components within a tubular frame structure.
- Bicycle Operating Device Wireless Control via Multi-Directional Switch
A bicycle operating device integrates an electrical switch into a multi-directional additional operating member to generate electric signals for wireless transmission.
- Hydraulic Brake Master Cylinder Tool-Free Free Stroke Adjustment
Nested knurled adjuster rotates a rod-mounted seal to change channel distance, eliminating tool requirements for brake pad contact point adjustment.
- Bicycle Shifting Device with Asymmetric Pawl Mechanism
A bicycle operating device uses two pivotally mounted pawls with distinct contact point distances to enable independent ratchet engagement.
- Twist Grip Rotary Actuator With Spring-Loaded Pressure Element
A twist grip actuator uses a spring-loaded pressure element to mechanically scan electrical control variables.
- Bicycle Bar End Attachment Radial Shoe Compression
A bicycle bar end attachment uses a rotating member and transmission structure to compress a shoe radially against the handlebar inner surface.
- Metallic Snowmobile Choke Lever Assembly
Replacing brittle plastic components, this metallic choke lever assembly resists breakage and maintains functionality in snowmobile engines.
- Bicycle Motor Controller Automatic Boost Adjustment
A bicycle motor controller sets boost and assist ratios via user input to manage drive motor output.
- Inclined Cylinder Bicycle Shifter Design
A 45-degree cylinder inclination breaks parallel alignment constraints to improve design freedom and manufacturing simplicity.
- Bicycle Handlebar Mounting Device with Asymmetric Guide Structure
An asymmetric guide structure with interlocking recess and protrusion elements prevents unintentional removal of the holding member while reducing part count.
