Solution Overview
Problem
Conductive paths with welded single-core and stranded wires face disconnection risks when subjected to external forces that skew the axes of the wires, compromising connection reliability.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a welded connection is used between single-core wire and stranded wire, then axial pulling strength is improved, but connection reliability deteriorates when external forces cause axial skewing
Solution Approach 1:
A support member is introduced as an intermediary component between the single-core wire and stranded wire. This support member maintains coaxial alignment of the two conductors, preventing relative skewing that would compromise the welded connection. The support member thus mediates the interaction between the two wires, ensuring they remain properly aligned under external forces while allowing the welded connection to maintain its axial strength.
2Reliability
If a rigid support structure is added to maintain coaxial alignment, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The support member is designed as a thin-walled cylindrical structure that provides rigid coaxial alignment maintenance while remaining flexible enough to be integrated with the existing conductor assembly. This thin-walled structure achieves the alignment function without adding significant structural complexity, as it can be简单地套设 on the conductors and maintained by the holding member.
3Stability of the object's composition
If a holding member is used to integrate the support member with conductors, then coaxial stability is improved, but manufacturing complexity increases
Solution Approach 1:
The support member is nested within the holding member, creating a compact integrated assembly. The holding member envelops the support member and conducts, forming a nested structure that maintains coaxial stability while simplifying the overall assembly. This nesting approach allows the components to be manufactured separately but assembled in a straightforward sequential manner, reducing manufacturing complexity.
Solution Approach 2:
The holding member utilizes heat shrinkage phase transition to achieve integration. By applying heat, the holding member shrinks and tightly secures the support member and conductors together, creating a stable coaxial assembly. This phase transition approach simplifies the integration process, as it requires only heating rather than complex mechanical fastening operations.

AI summary
A conductive path includes: a first conductor in which a terminal end portion serves as a first connection portion; a second conductor in which a second connection portion at a terminal end portion is coaxially fixed to the first connection portion; a support member that is more rigid than the first and second conductors, and is disposed so as to extend along a fixed portion between the first and second connection portions; and a heat-shrinkable tube (holding member) that integrates the support member with the first and second conductors while enveloping the support member. Even when an external force acts on the first and second conductors so as to skew the axes of the two conductors, the support member and the heat-shrinkable tube keep the two conductors in the coaxial state.
