Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a noise reduction tool uses a magnetic body with a fixed structure to accommodate specific wire diameters, then the noise reduction performance is ensured for that specific diameter, but the tool cannot be shared between electric wires having greatly different diameters
Solution Approach 1:
The noise reduction tool incorporates a flexible belt-like magnetic body that can dynamically adjust its winding diameter to accommodate different wire diameters. The fixing member is designed to be flexible and adaptable, allowing the same tool structure to maintain effective magnetic coupling across a range of wire sizes without requiring multiple specialized tools for each diameter.
2Ease of manufacture
If a noise reduction tool uses adhesive bonding to attach the magnetic body to the wire, then the assembly is simplified, but durability is compromised due to heat resistance and aged deterioration issues
Solution Approach 1:
The patent replaces the chemical bonding method (adhesive) with a mechanical bonding system. The fixing member is designed to mechanically secure the magnetic body to the wire through friction, compression, or interlocking mechanisms, eliminating the need for adhesives. This mechanical approach provides superior durability and heat resistance while maintaining ease of assembly through simple mechanical operations.
3Adaptability or versatility
If a noise reduction tool uses a fixed-diameter magnetic body, then manufacturing precision is maintained, but the tool cannot adapt to varying wire diameters without requiring multiple tool variants
Solution Approach 1:
The noise reduction tool employs a flexible magnetic body whose winding diameter can change according to the wire diameter. The fixing member is designed with flexible characteristics that allow it to adapt its dimensions while maintaining sufficient precision through elastic recovery and consistent compression forces, ensuring reliable magnetic coupling across different wire sizes without requiring multiple precision-manufactured tool variants.

AI summary
A noise reduction tool includes a magnetic body that can be wound around, more than one turn around an axis of an electric wire or an electric wire bundle, the electric wire or the electric wire bundle and a fixing member that fixes, to each other, overlapping sections of a stacked portion in the magnetic body having a winding shape wound around the electric wire or the electric wire bundle and fixes the magnetic body to the electric wire or the electric wire bundle while keeping the winding shape of the magnetic body. The magnetic body is capable of changing a winding diameter according to an electric wire diameter of the electric wire or an electric wire bundle diameter of the electric wire bundle, and the fixing member fixes, to each other, the overlapping sections corresponding to a winding diameter of the magnetic body irrespective of the winding diameter.
