Slide Door Link Arm Wire Routing With Integrated Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness wiring structures for link type slide doors face challenges in ensuring adequate space for wiring between the vehicle body and the slide door, particularly when using a link arm to support the door in a sliding manner.
Innovation Solution
A wire harness wiring structure that includes a link arm with a groove-shaped portion along its extending direction to accommodate wires, allowing the wire to be slidably supported and rotated relative to the vehicle body and door main body, with a cover portion to protect and secure the wire in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a link arm is used to support the door main body in a sliding manner, then the door can move smoothly relative to the vehicle body, but adequate space for wiring between the vehicle body and the door main body cannot be ensured
Solution Approach 1:
The wire is nested within the groove portion formed on the link arm, allowing the wiring to be accommodated within the existing structural space of the link arm rather than requiring additional external space. This resolves the contradiction by utilizing the internal volume of the link arm for wiring while maintaining the door's sliding functionality.
Solution Approach 2:
The groove portion is formed along the extending direction of the link arm, utilizing the longitudinal dimension of the link arm to accommodate the wire. This dimensional approach allows wiring space to be created within the existing structural footprint, ensuring adequate wiring accommodation without compromising the door's sliding movement capability.
2Ease of manufacture
If the wire is exposed outside the link arm, then the wire can be easily accessed, but the wire's integrity is compromised during door movement
Solution Approach 1:
The wire is nested within the groove portion of the link arm, which protects the wire from external damage while maintaining a controlled and accessible routing path. The groove acts as a protective channel that secures the wire during door movement while allowing for potential future access if needed.
Solution Approach 2:
The groove portion serves as an intermediary structure between the wire and the external environment, providing mechanical protection and stable positioning. This intermediate structure shields the wire from damage during door operation while maintaining the wire's functional connectivity.
3Area of stationary object
If additional wiring space structures are added to the link arm, then proper wiring accommodation is achieved, but the device complexity increases
Solution Approach 1:
The groove portion for wire accommodation is merged into the link arm structure itself, combining the structural and wiring functions into a single integrated component. This eliminates the need for separate wiring channels or additional structural elements, thereby providing proper wiring accommodation without increasing overall device complexity.
Solution Approach 2:
The link arm is designed with multi-functionality, serving both as the mechanical support for door sliding and as the structural element that accommodates wiring through its groove portion. This universal design approach allows a single component to fulfill multiple functions, avoiding the need for additional dedicated wiring structures.

AI summary
A wire harness wiring structure includes at least a main link arm and a wire. The main link arm has one end rotatably connected to the vehicle body and a different end rotatably connected to the door main body, and slidably supports the door main body with respect to the vehicle body while relatively rotating with respect to the vehicle body and the door main body. The wire is wired along the main link arm, and connects a connection target on the vehicle body side and a connection target on the door main body side. Then, the main link arm includes a groove portion that is formed into a groove shape along an extending direction in which the main link arm extends, and can accommodate the wire.
