Sensor Cable Routing in Motorcycle Brake Caliper Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sensor unit attachment structure for saddle-riding-type vehicles results in a long and meandering sensor cable, leading to increased costs and unnecessary slack, as the cable is bent and drawn in a way that causes it to meander significantly in the vehicle's front-to-rear direction.
Innovation Solution
The proposed solution involves attaching the wheel speed sensor to a lower position than the brake caliper bracket, with the sensor cable drawn upward and inward, then outward to be supported by the brake caliper bracket, minimizing meandering and maintaining a shorter cable length. This configuration includes a brake caliper bracket with a frontward extension part to regulate the sensor cable's displacement and a regulation rib to secure the sensor, ensuring appropriate fixation without position displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor cable is arranged to avoid the bolt fastening parts by bending in a meandering path, then the cable can be routed without interference, but the cable length increases significantly and costs rise
Solution Approach 1:
The patent changes the routing dimension by having the sensor cable pass through the thickness direction of the sensor stay rather than routing it along the length direction. The cable penetrates the sensor stay from one side to the other, utilizing the Z-dimension (thickness) to achieve a straighter, shorter path while still avoiding interference with fastening operations.
2Adaptability or versatility
If the sensor cable is drawn in a meandering path to reach from the sensor to the control unit, then the cable can connect all components, but unnecessary slack is created
Solution Approach 1:
The sensor cable is routed through the sensor stay during the assembly process before final installation. By preliminarily positioning the cable through the stay's thickness direction during assembly, the cable maintains a taut, direct path that prevents slack while ensuring proper connectivity between the sensor and control unit.

AI summary
In a saddle-riding-type vehicle sensor unit attachment structure, a brake caliper bracket that holds the brake caliper is attached to the rearward extension stay of the front fork, the wheel speed sensor is attached to a lower position than the rearward extension stay of the brake caliper bracket, and the sensor cable is arranged toward an upward direction at an inner side in a vehicle width direction of the rearward extension stay and is then drawn to an outer side in a vehicle width direction of the brake caliper bracket at an upper position than the rearward extension stay to be supported by the brake caliper bracket.
