Portable Braking System TRIZ Cases

Pneumatic actuators position scotch elements based on sensor data, resolving the trade-off between high safety levels and complex manual control structures.

A tire wedge system with a compressible portion reversibly deforms to fit vehicle tires.

Grate locks anchor the base while a retractor strap secures the tire, preventing upward movement during transit.

Internal webs reinforce a low-profile wheel chock body, preventing damage to wheel-well components during installation on vehicles with restricted clearance.

Sliding wheel chocks engage base plate stoppers to prevent forward and rearward vehicle movement without invasive structures.

A flexible elongate member wraps around vehicle wheels to prevent slippage on irregular surfaces while accommodating various wheel diameters.

Rotating arms form a V-shape to block wheels, extracting the mechanism from the floor to prevent dirt and ice accumulation.

Camera feedback system calculates compensating distance for motor vehicle wheels, resolving visibility constraints during manual leveling operations.

Segmented polymer guides reduce ski friction while grooved surfaces provide ATV traction on smooth trailer beds.

A composite jack block uses a central opening to store crank components, eliminating the need for stacking multiple units and reducing overall weight.

Segmented wheel cradles and sliding locks block lug nut access, resolving theft protection versus device complexity.

A toggle wedging shoe uses a spring mechanism to retract its ramp from under a wheel tread.

A foot-operated wheel chock uses a rocking body and over-center locking mechanism to secure two-wheeled vehicles.

Kinetic energy powers wireless signaling in a wheel chock, eliminating cable tripping hazards and ensuring reliable operation.

A wheel chock alarm system uses a retractable cable to monitor device displacement from its installed position.

A railway wheel block mechanism rotates a movable part to achieve tilted or ejected positions for secure vehicle placement.

A flexible U-shaped roller stop uses a bendable band to adjust side leg spacing for secure wheel engagement.
