Flat Wiring Member Layout Using Fixed and Free Parallel Wires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in easily keeping multiple electrical wires flat using a sheet material.
Innovation Solution
A wiring member design that includes a first sheet material, a second sheet material, and fixed and free wire-like transmission members, where the second sheet material is fixed to the first sheet material at two points, and the free wire-like transmission members are disposed parallel to the fixed members between the first and second sheet materials, allowing their routes to be regulated by the fixed members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all wire-like transmission members are fixed to the sheet material, then the routing and positioning of wires is controlled, but the manufacturing complexity and time increase due to requiring fixation for each wire
Solution Approach 1:
The wire-like transmission members are segmented into two categories: fixed wires (first and second wire-like transmission members) that are attached to the sheet material, and free wires (third wire-like transmission member) that are not fixed. This segmentation allows different wires to have different fixation states, reducing overall manufacturing complexity while maintaining routing control where needed.
Solution Approach 2:
The fixed wire-like transmission members act as intermediaries that define the routing path. The free wire-like transmission member follows the route defined by the fixed wires, using them as a guide or template. This intermediary approach allows indirect control of the free wire's position without direct fixation, improving manufacturing efficiency.
2Shape
If multiple wires are kept flat using a sheet material, then the wiring member maintains a compact structure, but the ease of manufacture decreases when requiring direct welding of insulating coverings
Solution Approach 1:
The requirement for direct welding between insulating coverings is extracted and removed from the manufacturing process. Instead, the patent uses a structure where wires are positioned between two sheet materials, eliminating the need for complex welding operations while maintaining the flat wiring structure.
Solution Approach 2:
The patent uses flexible sheet materials to maintain the flat structure of the wiring member. The sheet materials can be bent and shaped to keep wires flat without requiring rigid structures or complex welding, thereby simplifying manufacturing while maintaining the desired compact flat shape.
3Stability of the object's composition
If the second sheet material is fixed at multiple points, then the structural stability and wire positioning is improved, but the manufacturing time and complexity increase
Solution Approach 1:
The fixation points of the second sheet material are segmented into specific locations (first and second fixing parts) rather than continuous fixation. This segmentation provides sufficient stability for wire positioning at critical points while reducing the total fixation time and complexity compared to full-surface bonding.

AI summary
A wiring member includes: a first sheet material; a second sheet material overlapped with the first sheet material; and a fixed wire-like transmission member and a free wire-like transmission member located between the first sheet material and the second sheet material, wherein the second sheet material is fixed to the first sheet material in a first fixing part and a second fixing part away from the first fixing part, the fixed wire-like transmission member is fixed to the first sheet material between the first fixing part and the second fixing part, and the free wire-like transmission member is disposed between the first sheet material and the second sheet material while being parallelly arranged to the fixed wire-like transmission member.
