Automotive Harness Clip With L-Shaped Lock Against Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harness clips for automobiles fail to stably hold the harness on the rocker panel due to easy disengagement under load, particularly from the kicking plate or carpet, leading to instability.
Innovation Solution
A harness clip design featuring a base portion with a leg for engagement on the rocker panel, a side wall with a hinge-connected curved harness holding portion, and a lock portion forming an L-shape to securely engage with the base, along with additional features like an engagement portion for the kicking plate support and a rib for carpet retention, enhancing stability and resistance to loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the retaining claw and retaining groove engagement is used to hold the harness, then the harness can be retained, but the engagement can be easily canceled when large loads are applied, leading to disengagement
Solution Approach 1:
The invention transitions from a single-point engagement (claw in groove) to a multi-point engagement system. The L-shaped lock portion engages with the base portion at multiple locations: the distal end engages with the base portion while the angular portion contacts the upper surface of the base portion, creating a two-dimensional engagement area that distributes loads and prevents disengagement
Solution Approach 2:
The lock portion is designed to engage with the base portion before the harness is subjected to large loads. This preliminary engagement establishes a stable connection that prevents the retaining claw and groove engagement from being canceled when loads are applied
2Device complexity
If the first and second bow-like piece portions are engaged through retaining claw and groove, then the harness can be held, but the structure becomes complex and prone to disengagement
Solution Approach 1:
The invention merges the functions of multiple separate components into a single integrated lock portion. The lock portion combines the retaining claw, the L-shaped engagement structure, and the angular portion contact surface into one unified component that engages with the base portion, simplifying the overall structure while maintaining reliability
Solution Approach 2:
The lock portion is segmented into functional zones: the distal end for primary engagement with the base portion, and the angular portion for secondary contact with the upper surface. This segmentation allows each zone to perform its specific function while working together to provide stable retention

AI summary
A harness clip includes a base portion having a leg portion for engagement with a rocker panel, a side wall portion standing on and extending from one side edge of the base portion, and a harness holding portion which is connected to the side wall portion through a hinge portion, and a lock portion for engagement with the base portion at a distal end edge portion of the harness holding portion. The distal end edge portion of the harness holding portion is formed into a substantially L-shape when viewed from an end surface thereof to provide an angular portion, and this angular portion is locked to the base portion in contacting relation to an upper surface of the base portion. Therefore, even when a load is applied to the harness clip, the harness can be stably held without canceling the engagement of the lock portion with the base portion.
