Wiring Member Shape Maintaining Uneven Surface Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat cables struggle to maintain contact with uneven surfaces, leading to separation and inefficient arrangement when attached to such surfaces.
Innovation Solution
A wiring member comprising a flat wiring member with wire-like transmission members and a base member, along with a shape maintaining member that keeps the wiring member in an uneven shape, allowing it to be positioned closely to the surface by forming fixing holes and protrusions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat cable is arranged along an uneven surface, then the cable can be attached to the surface, but the cable significantly separates from the uneven surface having a difference in height
Solution Approach 1:
The wiring member is divided into multiple segments including a flat wiring member portion and a shape maintaining member portion. This segmentation allows different parts to serve different functions: the flat portion maintains electrical connection while the shape maintaining portion adapts to uneven surfaces, resolving the contradiction between maintaining flat shape and ensuring reliable contact.
Solution Approach 2:
The shape maintaining member is configured with a curved or bent shape that corresponds to the uneven surface geometry. This curvature allows the wiring member to conform to the uneven surface while the flat wiring member portion remains intact for electrical connections, solving the separation problem caused by height differences.
2Ease of operation
If the flat cable is made thin to maintain flexibility, then flexibility is improved, but the cable cannot maintain contact with uneven surfaces
Solution Approach 1:
The cable system is segmented into a thin flexible flat wiring member and a separate shape maintaining member. The thin flat portion preserves flexibility for ease of installation and routing, while the attached shape maintaining member provides the necessary structural support to bridge gaps and maintain contact with uneven surfaces.
Solution Approach 2:
The wiring member combines different structural elements: a thin flexible flat cable portion for electrical transmission and a shape maintaining member (which may be rigid or semi-rigid) for structural support. This composite structure integrates the advantages of both flexibility and surface adaptation.
3Reliability
If a shape maintaining member is added to keep the wiring member in an uneven shape, then contact with uneven surface is improved, but the device complexity increases
Solution Approach 1:
The shape maintaining member is merged with the flat wiring member to form an integrated wiring member assembly. This combination allows the shape maintaining function to be incorporated without requiring separate installation steps or additional components, thus improving reliability while minimizing the increase in device complexity.
Solution Approach 2:
The shape maintaining member is designed to automatically conform to the uneven surface geometry through its inherent structural properties (such as pre-bending or flexible mounting). This self-adjusting capability eliminates the need for complex adjustment mechanisms or additional fastening components, maintaining simplicity while ensuring reliable contact.

AI summary
The wiring member includes a flat wiring member and a shape maintaining member. The flat wiring member includes a plurality of wire-like transmission members (for example, insulated wires) and a base member (for example, a sheet member) keeping the plurality of wire-like transmission members in a flat state. The shape maintaining member is provided in at least a part of the flat wiring member to keep at least the part of the flat wiring member in an uneven shape.
