Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart clothing technologies require multiple components to connect flexible conductors on opposite surfaces to a single contact, increasing complexity and component count.
Innovation Solution
A sheet type conductive member with a tongue portion that projects and folds back to form a contact connecting portion, allowing flexible conductors on opposite surfaces to be connected to a single contact without a dedicated linking member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated linking conductive member is used to connect flexible conductors on opposite surfaces to a contact, then electrical connectivity is achieved, but the number of components and device complexity increases
Solution Approach 1:
The patent merges the functions of multiple separate components (flexible substrate, conductive members, and linking conductive member) into a single integrated sheet type conductive member. The sheet body with front and rear surfaces integrates the flexible substrate and conductive members, while the tongue portion integrates the linking conductive member function, eliminating the need for a separate dedicated linking conductive member and reducing overall component count.
Solution Approach 2:
The sheet type conductive member serves multiple functions simultaneously: it provides the flexible substrate, carries conductive members on both surfaces, and includes a tongue portion that acts as a linking conductive member. This multi-functional design eliminates the need for separate dedicated components for each function.
2Reliability
If a dedicated linking conductive member is used to connect flexible conductors on opposite surfaces, then electrical connectivity is ensured, but the number of components increases
Solution Approach 1:
The patent combines multiple functional elements into a single sheet type conductive member. The sheet body integrates the flexible substrate and conductive members, while the tongue portion integrates the linking conductive member function, reducing the total number of components from multiple separate parts to a single integrated structure.
3Reliability
If flexible conductors are connected through multiple contact points using a linking conductive member, then electrical connectivity is achieved, but the contact path becomes more complex
Solution Approach 1:
The patent extracts and eliminates the intermediate linking conductive member from the contact path. By providing direct contact between the flexible conductors on opposite surfaces through the sheet body structure, it removes the intermediate component that created complexity in the contact path, simplifying the electrical connection while maintaining connectivity.

AI summary
A sheet type conductive member includes a tongue portion projecting in a tongue shape in a predetermined plane, a contact arrangement region in which a contact of a connector is arranged being laid out on a front surface of the sheet type conductive member, a first flexible conductor being exposed on the contact arrangement region, a second flexible conductor being exposed on a rear surface of the tongue portion, at least part of the tongue portion being folded back to a front surface side of the sheet type conductive member so that a contact connecting portion composed of part of the first flexible conductor and part of the second flexible conductor is formed in the contact arrangement region.
