Wire Harness Path Regulating Member for Flexible Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses require significant time and cost to change wiring paths due to the need for remaking molds for protectors, which are resin molded articles with open sides, making it difficult to modify the wiring configuration efficiently.
Innovation Solution
A wire harness design that uses a path regulating member with higher flexural rigidity than the wires, allowing for two-dimensional or three-dimensional bending to easily change the wiring path, with an electromagnetic shielding member covering the path regulating member and wires fixed using multiple fixation members, enabling flexible reconfiguration without the need for mold remaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a protector (resin molded article) is used to regulate the wiring path, then the wiring path can be regulated, but changing the wiring path requires remaking molds which increases cost and time
Solution Approach 1:
The invention divides the path regulation function from the fixed protector structure into a separate path regulating member that can be independently configured. This allows the wiring path to be segmented and reconfigured without remaking the entire protector mold, enabling flexible path changes while maintaining the protective function.
Solution Approach 2:
The path regulating member is designed to be bendable in two dimensions or three dimensions, providing dynamic adaptability to different wiring path requirements. This dynamic characteristic allows the same path regulating member to be reused for different path configurations without requiring new molds, thus reducing time and cost for path changes.
2Adaptability or versatility
If the path regulating member is made flexible to allow bending, then the wiring path can be easily changed, but the structural strength may be compromised
Solution Approach 1:
The path regulating member is constructed from composite materials or a metal material that provides both the necessary flexibility for bending and the structural strength to maintain its shape and protect the wires. This composite structure enables the member to be bent into different configurations while retaining sufficient strength to perform its protective and regulatory functions.
3Object-affected harmful factors
If an electromagnetic shielding member is added to cover the wires, then electromagnetic noise is reduced, but the device complexity increases
Solution Approach 1:
The electromagnetic shielding member is merged with the path regulating member or integrated into the existing wire harness structure, combining the path regulation function with the electromagnetic shielding function in a single integrated component. This merging approach provides electromagnetic noise protection while minimizing the increase in device complexity.
Solution Approach 2:
The path regulating member is designed to serve multiple functions: it regulates the wiring path, provides structural support, and when made of metal material, provides electromagnetic shielding. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while still providing electromagnetic noise reduction.
