Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic core is added to cover target wiring for noise countermeasures, then noise resistance is improved, but device complexity increases
Solution Approach 1:
The magnetic core is integrated with the base member to form a unified structure. The base member serves dual functions: maintaining the flat state of multiple wirings and supporting the magnetic core that covers the target wiring. This merging eliminates the need for separate noise countermeasure components while achieving effective electromagnetic shielding.
Solution Approach 2:
The base member is designed to perform multiple functions simultaneously: it keeps the plurality of wirings in a flat state and provides a mounting structure for the magnetic core. This multi-functional design reduces the overall number of components needed in the wire harness system while maintaining noise resistance capabilities.
2Reliability
If multiple noise countermeasure components are added to wire harness, then noise resistance is improved, but ease of manufacture deteriorates
Solution Approach 1:
By combining the magnetic core with the base member into a integrated structure, the assembly process is simplified. Instead of separately installing multiple noise countermeasure components along the wire harness, the integrated base member with embedded magnetic core can be installed as a single unit, significantly improving ease of manufacture.
