Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiring harnesses require an energizing device to melt the exterior member for disassembly, making the process time-consuming and labor-intensive.
Innovation Solution
A wiring harness design featuring a tape member bundled by a tape cutting wire that can be easily cut by pulling an end part, allowing for efficient disassembly without the need for additional energizing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a heating wire and energizing device are used to melt the exterior member for disassembly, then the exterior member can be removed for recycling, but the disassembly process becomes time-consuming and requires additional equipment
Solution Approach 1:
A cutting wire is pre-installed within the exterior member at a predetermined location during manufacturing. This cutting wire remains dormant during normal operation but becomes activated during disassembly to automatically sever the exterior member, eliminating the need for external heating equipment and manual labor. The preliminary placement of the cutting wire enables self-contained disassembly capability.
Solution Approach 2:
The disassembly function is extracted from the exterior member itself by incorporating a cutting wire that can be independently activated. This allows the exterior member to possess inherent disassembly capability without requiring external energizing devices or heating wires, simplifying the overall system while maintaining recyclability.
2Ease of operation
If a heating wire is embedded in the exterior member to enable melting and removal, then disassembly is possible, but the structure becomes more complex and requires additional components
Solution Approach 1:
The cutting wire is integrated within the exterior member structure during manufacturing, merging the disassembly function with the exterior member itself. This eliminates the need for separate heating wires, energizing devices, and control systems, reducing the total component count while enabling simple disassembly operations through cutting wire activation.
Solution Approach 2:
The cutting wire serves multiple purposes: it is embedded within the exterior member structure, provides the disassembly cutting function, and can be activated through various means (pulling, heating, etc.). This multi-functional design reduces the need for dedicated disassembly components while maintaining operational simplicity.
