Wire Harness Routing Device for Sliding Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness configurations for vehicles with sliding seats require an excess length absorption box, which reduces available space and complicates the routing of wire harnesses.
Innovation Solution
A wire harness routing device that uses a rail with an insertion hole and a slider to accommodate excess length portions of the wire harness within the rail, allowing the wire harness to deform and fold back, eliminating the need for an external absorption box, and includes features like a harness routing groove and a cover opening/closing mechanism to manage wire routing and prevent protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an excess length absorption box is provided outside the rail to accommodate the excess length portion of the wire harness, then the wire harness can be properly routed, but the available space in the vehicle is reduced
Solution Approach 1:
The patent merges the excess length absorption function with the existing rail structure by routing the wire harness through the insertion hole of the rail. The excess length portion is folded back and held within the rail itself, combining two functions (routing and absorption) into a single integrated structure, thereby eliminating the need for a separate absorption box and preserving vehicle space
Solution Approach 2:
The excess length portion of the wire harness is nested within the rail structure. The wire harness is routed through the insertion hole, and the excess portion is folded back and contained within the same insertion hole, creating a nested configuration where the absorption function is embedded within the existing rail geometry
2Reliability
If an excess length absorption box is provided outside the rail, then the excess length can be accommodated, but the configuration becomes more complex
Solution Approach 1:
The patent combines the routing function and excess length absorption function into a single integrated rail structure. By routing the wire harness through the insertion hole and allowing the excess portion to be folded back within the same hole, the design eliminates the need for separate absorption boxes, guards, and complex routing mechanisms, thereby simplifying the overall configuration
Solution Approach 2:
The rail structure is given multiple functions: it serves both as a routing path for the wire harness and as an absorption mechanism for the excess length portion. The insertion hole simultaneously guides the wire harness and contains the folded-back excess portion, making the rail a multi-functional component that reduces overall system complexity

AI summary
A wire harness routing device includes a rail in which an insertion hole is formed, a slider that is inserted into the insertion hole and that slides with respect to the rail, and a wire harness that is routed in the insertion hole and moves in accordance with sliding of the slider, and an excess length portion of the wire harness that is generated in accordance with movement of the wire harness deforms in the insertion hole and is held in a state in which it is accommodated in the insertion hole.
