Integrated Brake and ABS Harness for Compact Vehicle Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ABS sensor cables and electric brake cables in vehicles are separately installed, leading to inefficient use of wiring space and complicated wiring work due to limited space and increased complexity.
Innovation Solution
A complex harness integrating an electric brake cable and an ABS sensor cable within a common outer sheath, with optional features like connectors, crosslinked thermoplastic resins, and a shield conductor to reduce fusion-adhesion and noise interference, allowing for easier separation and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ABS sensor cable and electric brake cable are separately installed, then each cable can be independently installed and maintained, but the wiring space is wasted and the wiring work becomes complicated
Solution Approach 1:
The patent combines the ABS sensor cable and electric brake cable into a single integrated harness assembly. The outer sheath encompasses both inner cables, creating a unified structure that reduces the number of separate wiring operations needed while maintaining the functional independence of each cable through their separate inner sheaths and connectors.
2Ease of operation
If ABS sensor cable and electric brake cable are separately installed, then each cable can be independently replaced, but the wiring space usage is inefficient
Solution Approach 1:
The patent implements a nested structure where the ABS sensor cable and electric brake cable are both contained within a common outer sheath. Each cable maintains its own inner sheath, creating a nested arrangement that maximizes space utilization while preserving the ability to access and replace individual cables when needed.
3Stability of the object's composition
If outer sheath and inner sheath are tightly bonded, then the structure is more stable, but separation becomes difficult during installation and maintenance
Solution Approach 1:
The patent introduces a separator as an intermediary layer positioned between the outer sheath and inner sheath. This separator prevents direct fusion-adhesion between the sheath layers, maintaining structural stability while enabling easy separation of the cables from the outer sheath during installation and maintenance operations.

AI summary
A complex harness includes first electric wires, each of which includes a first center conductor and a first insulation that covers the first center conductor, a cable including second electric wires, each of which includes a second center conductor and a second insulation that covers the second center conductor, and an inner sheath that covers the second electric wires, and an outer sheath covering the first electric wires and the cable collectively. The first electric wires are extended from an end of the outer sheath. The cable is extended from the end of the outer sheath in a state where the second electric wires are collectively covered by the inner sheath in such a manner that an extension length of the cable from the end of the outer sheath is greater than an extension length of the first electric wires from the end of the outer sheath.
