Slide Door Harness Rotating Shaft Wiring Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slide door harnesses have inadequate wiring solutions that do not effectively manage the positioning and rotation of wiring materials with the slide door's movement, leading to potential interference and stress on the wiring components.
Innovation Solution
A slide door harness design featuring a vehicle body-side fixing portion and a door-side fixing portion with rotating shafts that allow the wiring material to rotate around two axes, ensuring it is properly positioned across the vehicle body and slide door, avoiding interference with the inner surface member during the door's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wiring material is fixed rigidly to the slide door and vehicle body, then the wiring position is stable, but the wiring cannot accommodate door movement and rotation, causing stress and potential damage
Solution Approach 1:
The patent applies the dynamics principle by introducing rotating shafts that enable the wiring material to dynamically adjust its position and orientation during door movement. The first rotating shaft allows rotation in the door slide direction, while the second rotating shaft enables rotation perpendicular to the door surface, creating a dynamic wiring system that adapts to various door positions without stress accumulation
Solution Approach 2:
The wiring fixing system is segmented into multiple independent rotating components. The first rotating shaft and second rotating shaft are separate, independently functioning elements that divide the complex movement accommodation task into manageable rotational degrees of freedom, allowing each segment to handle specific aspects of door movement
2Object-affected harmful factors
If the wiring material is positioned to avoid interference with the inner surface member, then the wiring does not interfere with door components, but the wiring path becomes more complex requiring multiple rotating shafts
Solution Approach 1:
The patent resolves the interference problem by adding rotational dimensions to the wiring fixing mechanism. Instead of simply rerouting the wiring in linear space, the invention introduces two rotational degrees of freedom that allow the wiring to dynamically reposition itself in three-dimensional space, avoiding interference with the inner surface member while maintaining a relatively compact structure
3Ease of operation
If the wiring material is allowed to rotate freely during door movement, then the wiring accommodates movement smoothly, but the wiring may rotate excessively causing tangling or interference
Solution Approach 1:
The patent applies preliminary anti-action by designing the rotating shaft mechanism with predetermined rotational limits and guidance features. The first rotating shaft is configured to rotate only within the range needed for door slide movement, and the second rotating shaft is limited to rotations perpendicular to the door surface, preventing excessive rotation and potential tangling before they can occur

AI summary
A slide door harness includes a wiring material, a vehicle body-side fixing portion provided in a vehicle body to rotatably hold an end of the wiring material below a lower end of an inner surface member of a slide door, and a door-side fixing portion provided on the slide door to rotatably hold another end of the wiring material, and the door-side fixing portion includes a holding portion configured to hold the another end of the wiring material toward the lower end side of the inner surface member, a first rotating shaft configured to allow the holding portion to rotate around a first rotation axis, and a second rotating shaft configured to allow the holding portion and the first rotating shaft to integrally rotate around a second rotation axis intersecting the first rotation axis.
