Bellows-Connected Wire Harness for Shielded Cable Bendability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness technologies do not adequately address the bendability of wires inserted into shield pipes, resulting in limited flexibility and potential mechanical stress.
Innovation Solution
A wire harness configuration that includes a first core wire, a second core wire, and an electrical connection with a bellows portion between the connecting portions, allowing for easy bending and flexibility.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a wire is inserted into a shield pipe to provide shielding, then electromagnetic interference protection is improved, but the bendability of the wire is deteriorated
Solution Approach 1:
The electrical connection is divided into three functional segments: a first connecting portion for electrical connection, a bellows portion for bending accommodation, and a second connecting portion for electrical connection. This segmentation allows each part to perform its specific function optimally while resolving the contradiction between shielding and bendability.
Solution Approach 2:
The bellows portion acts as an intermediary element between the two connecting portions. It mediates the mechanical stress and bending movements, protecting the electrical connection while enabling the wire to bend freely. The bellows structure absorbs mechanical deformation without transmitting it to the electrical connection points.
2Stability of the object's composition
If a flat portion is formed by pressing a conductive portion to maintain shape, then structural stability is improved, but bendability is deteriorated
Solution Approach 1:
The bellows portion is designed with a dynamic structure that can adapt its shape during bending operations. Unlike rigid flat portions, the bellows can expand and contract, allowing the wire to bend dynamically while maintaining electrical connection stability at the connecting portions.
Solution Approach 2:
The bellows portion functions as a flexible protective shell that covers the core wire. This flexible structure provides protection while accommodating bending movements, replacing the rigid flat portion approach with a more adaptable solution that maintains both stability and bendability.
