Slide Door Wire Harness Layout to Avoid Open-Door Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harnesses for slide doors are exposed when fully open, posing a risk of contact with occupants or cargo during entry and exit, necessitating a solution to prevent such interactions.
Innovation Solution
The wire harness is routed on the side of the slide direction using a link mechanism that connects the slide door and vehicle body, ensuring the harness is positioned behind the link mechanism when the door is fully open, thereby avoiding contact with occupants or cargo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wire harness is routed between the vehicle body and slide door, then electrical connection between the power source and switch is achieved, but the harness body becomes exposed when the slide door is fully open
Solution Approach 1:
The wire harness is routed in the depth direction (third dimension) of the vehicle interior by passing through the link mechanism, rather than simply spanning between the vehicle body and slide door in the lateral direction. This dimensional change positions the harness behind the link mechanism when the door is open, removing it from the hazardous exposure zone while maintaining electrical connectivity.
2Object-affected harmful factors
If the wire harness is positioned to avoid exposure, then contact with occupants and cargo is prevented, but the routing path becomes more complex
Solution Approach 1:
The link mechanism, which originally serves only as a mechanical connection for the slide door, is utilized as a dual-purpose routing path for the wire harness. By integrating the harness routing into the existing link mechanism structure, the patent avoids adding separate routing components or complex external pathways, thereby preventing contact while minimizing increases in overall system complexity.

AI summary
There is provided a harness body that electrically connects a first electrical connection target installed in a slide door and a second electrical connection target installed in a vehicle body, in which when the slide door is at a fully open position with respect to the vehicle body, the harness body is routed on a side of a slide direction during an opening operation of the slide door with respect to a link mechanism that couples the slide door and the vehicle body and reciprocates the slide door in the slide direction with respect to the vehicle body.
