Cycle Control Systems TRIZ Cases

A bicycle operating device integrates an adjusting structure to position a supporting structure relative to a base member.

Controller adjusts transmission ratio based on negative accelerator grip rotation to provide speed reduction without adding device complexity.

Asymmetric housing expands the center section beyond end portions to resolve volume versus appearance trade-offs.

A bicycle operating device integrates first and second structures on a base member to enable separate component control.

A bicycle cable control body moves within a defined range using a stopping member and biasing member for precise positioning.

A bicycle shift control device integrates a gear indicator within the housing using a flexible elongated member visible through a window.

External biasing members guide the lever and piston to reduce internal complexity while maintaining reliable hydraulic actuation for brakes and gears.

Nested linkage assembly converts lever rotation to linear slide movement, reducing required activation force and easing operation.

Segmenting the main and connection terminal substrates prevents water ingress through the USB port from causing short circuits in vehicle handle switches.

Segmented hydraulic pumps resolve the trade-off between device complexity and independent suspension control to reduce peddling-induced bobbing.

A bicycle operating device uses a movable member and biasing structure to manage operation cable movement.

Offset bushings accommodate outer post deformation from clamping pressure, maintaining inner post range of motion.

Nested radial master cylinders reduce aerodynamic drag while managing hydraulic fluid expansion inside the handlebar structure.

Segmented pedal tread with outer notch allows elastic cover insertion while protrusion locks position, resolving attachment difficulty.

Cutout in lower post enables internal actuator routing, resolving cable complexity and weight trade-offs.

Segmentation and dynamics principles allow the hose to rotate freely during installation, preventing oil leaks while maintaining a secure connection.

Winding feeder cables on an engaging section resolves space interference with the accelerator position sensor while housing components in a compact case.

A base member support abutment contacts the handlebar outer surface to pivotally couple an operating mechanism.
