Wire Harness Path Restrictor Structure for Higher Flexural Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wires with path restricting members have low flexural rigidity, leading to deviation from their intended path.
Innovation Solution
An electrical wire with a path restricting member that includes a main body covering more than half of the exterior tube's circumference, an insertion opening, and ribs protruding along the lengthwise direction, along with a fixing member supporting the path restricting member to enhance rigidity and prevent deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the path restricting member has a constant thickness, then the structure is simple and easy to manufacture, but the flexural rigidity is low causing the wire member to deviate from its path
Solution Approach 1:
The path restricting member transitions from uniform thickness to variable thickness, with thicker portions positioned strategically to enhance flexural rigidity where needed while maintaining simplicity in other areas. This local differentiation resolves the contradiction by providing structural reinforcement exactly where it is needed to prevent wire deviation.
Solution Approach 2:
The path restricting member combines material layers or structural components with different properties to achieve enhanced flexural rigidity. By using composite construction, the member gains the necessary strength to maintain wire positioning while keeping the overall design relatively simple and manufacturable.
2Stability of the object's composition
If the path restricting member covers a small portion of the exterior tube, then the structure is simpler, but the wire member deviates more easily from its path
Solution Approach 1:
Instead of uniformly covering the entire exterior tube, the path restricting member is strategically positioned to cover only the critical sections where wire deviation is most likely to occur. This targeted approach provides adequate path stability while minimizing the overall coverage area and structural complexity.
3Strength
If the path restricting member has low flexural rigidity, then the structure is more flexible and easier to install, but the wire member deviates from its intended path
Solution Approach 1:
The flexural rigidity parameter of the path restricting member is optimized to achieve a balance between maintaining wire position and facilitating installation. By carefully selecting material properties, thickness parameters, and geometric configurations, the member achieves sufficient rigidity to prevent deviation while remaining flexible enough for practical installation.

An electrical wire structure including: an electrical wire; an exterior tube covering an outer periphery of the electrical wire; and a path restrictor covering a range spanning more than half of an outer periphery of the exterior tube in a circumferential direction of the exterior tube, extending along a lengthwise direction of the exterior tube, and restricting a path along which the electrical wire is routed.
