Wheel-Side Wire Harness Routing for Flex Resistance in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses for connecting vehicle body-side devices and wheel-side devices face challenges in routing in small spaces and improving flex resistance.
Innovation Solution
A wire harness comprising a first wiring member with a longer outer path length and a second wiring member with higher flex resistance, where the first wiring member is routed along a detour path to avoid bending, and the second wiring member is routed along a shorter path that is more likely to bend.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the wire harness is routed through a compact path to save space, then the routing space requirement is reduced, but the flex resistance deteriorates due to increased bending
Solution Approach 1:
The wire harness is divided into multiple separate wiring members (first wiring member and second wiring member) with different flex resistance characteristics. This segmentation allows each wiring member to be optimally routed according to its specific properties, with higher flex resistance members taking shorter paths and lower flex resistance members taking longer detour paths, thereby resolving the contradiction between compact routing and flex resistance maintenance.
2Area of stationary object
If all wiring members are routed along the same short path, then the routing space is minimized, but the overall flex resistance of the wire harness deteriorates
Solution Approach 1:
Different wiring members are assigned different routing paths based on their local quality characteristics, specifically their flex resistance. The second wiring member with higher flex resistance is routed along a shorter path, while the first wiring member with lower flex resistance is routed along a longer detour path. This local quality differentiation ensures that each wiring member's routing is optimized for its specific properties, maintaining overall flex resistance while minimizing routing space.

AI summary
A wire harness for connecting a vehicle body-side device and a wheel-side device includes: a first wiring member; and a second wiring member that has higher flex resistance than the first wiring member. A first outer path length of the first wiring member is defined by a length of a first outer path portion of the first wiring member. A second outer path length of the second wiring member is defined by a length of a second outer path portion of the second wiring member. The first outer path length of the first wiring member is greater than the second outer path length of the second wiring member.
