Check-link Harness Guide for Vehicle Closure Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring harness guides for vehicles often suffer from pinching and damage when closure panels are moved to a closed position due to improper routing and limited space between the vehicle body and closure panels, and the uneven positioning of grommets increases these issues.
Innovation Solution
A check-link harness guide system that includes a base member with a mounting and receiving portion, a guide member, and a channel member pivotally connected to accommodate the movement of the wiring harness between the vehicle body and closure panels, ensuring the harness is not pinched and can span the necessary distance without being drawn into the guide member when the panels are closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If grommets are disposed at different heights to accommodate vehicle body and closure panel structures, then the wiring harness can be routed through the body structure, but the harness is pinched and damaged when the closure panel moves to closed position
Solution Approach 1:
The channel member is made movable relative to the guide member, allowing it to dynamically adjust its position as the closure panel moves between open and closed positions. This dynamic configuration prevents pinching of the wiring harness while maintaining proper routing guidance.
Solution Approach 2:
The channel member acts as an intermediary between the guide member and the wiring harness, providing a movable guide that accommodates panel movement. This intermediary structure prevents direct contact between the rigid grommets and the flexible harness, eliminating pinching.
2Length of moving object
If the wiring harness is made long enough to span the distance when closure panel is open, then the harness can connect body structure to closure panel, but the harness cannot be properly routed in the limited space between panels when closed
Solution Approach 1:
The channel member's movable configuration allows it to extend when the closure panel is open, guiding the long harness across the full distance. When closed, the channel member retracts or adjusts to accommodate the limited space, maintaining proper harness routing without requiring excessive length.
3Object-affected harmful factors
If fixed grommets are used at vehicle body and closure panel, then wire protection is provided, but the grommets pinch the harness during panel movement
Solution Approach 1:
The channel member is made movable relative to the guide member, allowing it to dynamically adjust its position as the closure panel moves between open and closed positions. This dynamic configuration prevents pinching of the wiring harness while maintaining proper routing guidance.
Solution Approach 2:
The channel member acts as an intermediary between the guide member and the wiring harness, providing a movable guide that accommodates panel movement. This intermediary structure prevents direct contact between the rigid grommets and the flexible harness, eliminating pinching.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The check-link harness guide system effectively prevents pinching of the wiring harness and ensures smooth movement of the closure panels by maintaining the harness's integrity and facilitating proper routing, even in limited spaces with varying grommet heights.
Implementation Method 1
A channel member is rotatably fixed to the receiving portion of the base member and movably received by the guide member

AI summary
A vehicle body structure includes first and second body structures defining first and second interior cavities. A mounting portion of the base member is fixed to the first body structure. A guide member is fixed to the second body structure. A channel member is movably received by the guide member. A first end of the channel member is rotatably fixed to a receiving portion of the base member and defines a first end opening such that the receiving portion extends into the first end opening. A second end is positioned within the second interior cavity and defines a second end opening with a channel extending from the first end opening to the second end opening. The channel member extends across an exterior space between the first and second body structures. A wiring harness passes through the channel from the first interior cavity to the second interior cavity.
