Wire Harness Protector Structure to Prevent Load-Induced Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle wire harnesses face damage due to loads acting on weak upper walls, which can cause the electric wires to be repeatedly subjected to stress, leading to potential damage.
Innovation Solution
A protector with a hollow main body that passes through a space between two articles, featuring a fixing part to secure it to one article and a suppression part to prevent inclination, dispersing loads and maintaining the protector's position using a spring structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wire harness circumvents components in the vehicle, then the wire harness can be routed around obstacles, but the upper wall may be subjected to load causing the electric wire to be repeatedly stressed
Solution Approach 1:
The patent introduces a protector as an intermediary component between the wire harness and the upper wall. This protector absorbs and distributes the load from the upper wall, preventing direct stress transmission to the electric wire. The mediator structure allows the wire to maintain its routing flexibility while being protected from harmful forces.
Solution Approach 2:
The patent applies beforehand cushioning by providing a protective structure in advance before the wire is subjected to repeated loading. The protector is pre-installed along the wire path, creating a cushioning effect that absorbs impact and distributes load before it can damage the electric wire.
2Device complexity
If a simple fixing structure is used, then the device complexity is reduced, but the protector may incline under load failing to protect the wire
Solution Approach 1:
The patent applies local quality by differentiating the functional properties of different parts of the protector. The fixing portion has different structural characteristics than the suppression portion. Each part is optimized for its specific function: the fixing part provides stable attachment while the suppression part provides load distribution and inclination prevention.
Solution Approach 2:
The patent incorporates dynamics by allowing the suppression part to flex and adapt under load. The structure can dynamically respond to applied forces, adjusting its configuration to maintain optimal protection while preventing inclination. This dynamic behavior ensures reliability without requiring overly complex rigid structures.
Applied Scientific Principles
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 protector effectively protects the electric wire by preventing inclination and distributing loads, thus reducing the likelihood of damage and noise from contact with other vehicle components.
Implementation Method 1
the suppression part is configured to suppress inclination of the protector main body with the fixing part serving as a base point
