Wire Harness Bracket Locking Structure for Stronger Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness fixing devices require complex structures and high costs due to the use of two locking components, which also result in insufficient retention force, causing the wire harness to be prone to loosening.
Innovation Solution
A wire harness fixing device comprising a bracket with a locking part and a locking component with a wire pressing portion, where the locking component is installed in the bracket and engaged with the locking part to press and hold the wire harness in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pair of locking components are used to fix the wire harness, then the wire harness can be secured in the bracket, but the structure becomes complex and the cost increases
Solution Approach 1:
The patent combines two separate locking components into a single integrated locking component that performs the function of both original components. The locking component includes a locking protrusion that engages with a locking groove in the bracket, and simultaneously includes a pressing portion that presses the wire harness against the bracket, thereby merging the locking function and pressing function into one component.
Solution Approach 2:
The single locking component is designed to perform multiple functions: it provides locking engagement through the locking protrusion and locking groove interface, and simultaneously provides pressing force through the pressing portion to secure the wire harness. This multi-functional design eliminates the need for separate locking and pressing components.

The locking component includes a locking protrusion that engages with a locking groove in the bracket, and simultaneously includes a pressing portion that presses the wire harness against the bracket, thereby merging the locking function and pressing function into one component.
Solution Approach 2:
The pressing portion of the locking component is designed with a curved surface that contacts the wire harness. This curved surface distributes the pressing force more effectively across the wire harness, increasing the friction force and preventing loosening while maintaining a compact component design.
