Wiring Harness Guide for Sliding Car Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring harness guiding apparatuses require large space, have complex structures, and are difficult to assemble due to the need for multiple components and slits in the floor mat, which complicates the routing of wiring harnesses between a car body and a slide body.
Innovation Solution
A simplified wiring harness guiding apparatus using a long-pipe-shaped rail with a protector and lead-out member that allows the wiring harness to be routed through a single slit, reducing the need for multiple slits and components, and featuring a support body mount member that moves along the width of the rail to accommodate dispersion and absorb rattle motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wiring harness rail and protector are arranged separately under the floor mat, then the wiring harness can be guided between the floor and seat, but the mount space increases and multiple slits are required in the floor mat
Solution Approach 1:
The patent combines the support body and protector into a single integrated component that slides along the support rail while guiding the wiring harness. This merging eliminates the need for a separate wiring harness rail, reducing mount space and requiring only a single slit in the floor mat instead of multiple slits.
Solution Approach 2:
The integrated support body serves multiple functions simultaneously: it supports the seat foot portion, guides the wiring harness through its internal passage, and protects the wiring harness. This multi-functionality reduces the number of components needed and simplifies the overall structure.
2Reliability
If a winding device with reel and spiral spring is used to manage excess wiring harness length, then the wiring harness can be pulled through the support rail, but the device complexity and mount space increase
Solution Approach 1:
The patent extracts and eliminates the complex winding device with reel and spiral spring from the system. Instead, the wiring harness is simply laid in the support rail and fixed at the seat side, with excess length managed passively without active winding mechanisms.
Solution Approach 2:
The wiring harness manages its own excess length passively by being laid along the support rail and fixed at the seat, without requiring an active winding device. The system uses the natural flexibility and routing of the wiring harness itself to handle excess length.
3Ease of operation
If a guide pipe is arranged inside the support body and large opening is provided, then the wiring harness can be passed through, but the support body structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent segments the support body into functional regions: an internal passage for wiring harness routing and an external fixing portion for securing the harness. This segmentation allows simple internal routing without requiring complex guide pipes or large openings, as the wiring harness passes through the dedicated passage and is fixed externally.
4Stability of the object's composition
If the support body is fixed rigidly to the rail, then the structure is stable, but it cannot accommodate dispersion and rattle motion
Solution Approach 1:
The patent makes the support body movable along the support rail instead of rigidly fixed, allowing it to accommodate dispersion and rattle motion dynamically. The support body can slide along the rail while maintaining wiring harness guidance, providing both stability and adaptability.

AI summary
A wiring harness guiding apparatus guides a wiring harness 4 between a floor of a car and a seat arranged slidably at the floor, and includes a support body 7A supporting the seat; a protector 8A guiding the airing harness 4 toward the seat; a rail arranging the support body 7A and the protector 8A slidably therein; and an excess portion receiving section receiving a excess portion of the wiring harness 4. The protector 8A includes a wiring harness fixing member 80 fixing the wiring harness 4 led into the rail; a lead-out member 83 extending with a pipe shape from the wiring harness fixing member 80 and leading the wiring harness 4 therethrough toward the slide body; and a support body mount member 87 arranged at a mounted member of the support body so as to be movable along a widthwise direction of the rail by having a clearance.
