Disc Brake Signal Cable Fixation Offset Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for mounting signal cables to disc brakes face clearance issues, particularly when the known clip protrudes and collides with components in applications requiring larger installation spaces, such as those with 19.5" wheels, limiting their suitability.
Innovation Solution
A signal cable fixation member with a connecting part that offsets the signal cable guide axis from the attachment part's engagement axis, allowing the signal cable guiding part to be displaced towards the lower edge of the cover plate, thereby increasing clearance and avoiding collisions with moving and heat-generating parts, while maintaining safety and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a known clip is used to fix the signal cable to the plate, then the signal cable can be held in place, but the clip protrudes from the surface and collides with components in applications requiring larger installation spaces
Solution Approach 1:
The signal cable guiding part is offset from the engagement axis by introducing a connecting part with specific geometry (first and second connecting elements spaced apart). This dimensional offset relocates the cable guidance function to a different spatial position, allowing the cable to be guided closer to the interior of the accommodation space while keeping the attachment point in its original location on the cover plate surface.
Solution Approach 2:
The fixation member is divided into distinct functional parts: an attachment part for securing to the cover plate, a connecting part with first and second connecting elements that provide structural support and offset, and a signal cable guiding part that actually guides the cable. This segmentation allows each part to be optimized independently for its specific function.
2Area of stationary object
If the signal cable guiding part is positioned closer to the interior of the accommodation space, then clearance is increased, but the cable may be closer to heat-generating and moving parts
Solution Approach 1:
The connecting part is configured with specific geometric properties (spaced apart connecting elements, predetermined offset distance) that create a localized protective structure. This structure provides mechanical support and maintains optimal positioning of the signal cable, ensuring it remains at a safe distance from heat-generating and moving parts while still achieving the desired clearance improvement.

AI summary
A system for mounting a signal cable to a disc brake includes a cover plate, an actuator opening in a region of the cover plate configured to allow passage of an actuation device, and a signal cable fixation member (80) for mounting the signal cable to the cover plate, the signal cable fixation member (80) including an attachment part (82) and a signal cable guiding part (84). The attachment part (82) engages with the cover plate and the signal cable guiding part (84) guides the signal cable towards a side edge of the cover plate. A connecting part (86) between the attachment part (82) and the signal cable guiding part (84) spaces apart a signal cable guide axis A of the signal cable guiding part (84) from an engagement axis B of the attachment part (82) by an offset d.
