Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one sheet-like magnetic body is wound around multiple electric wires bundled together, then the structure is simple and easy to manufacture, but it is difficult to ensure consistent intervals among the electric wires
Solution Approach 1:
The magnetic body is divided into multiple independent magnetic sheets, each wrapping around individual electric wires. This segmentation allows each wire to be independently positioned and spaced, ensuring consistent intervals while maintaining ease of manufacture through modular assembly.
Solution Approach 2:
The invention transitions from a single 2D sheet wrapped around bundled wires to multiple 2D sheets arranged in a dimensional configuration that individually encloses each wire. This dimensional reorganization enables precise interval control while preserving manufacturing simplicity.
2Object-affected harmful factors
If electric wires are bundled together and wrapped with a single magnetic body, then the noise reduction coverage is comprehensive, but the distance between adjacent wires cannot be maintained
Solution Approach 1:
By segmenting the magnetic body into multiple individual sheets, each wire receives dedicated magnetic shielding while maintaining its specific distance from adjacent wires. This ensures both comprehensive noise reduction coverage and proper wire spacing.
Solution Approach 2:
Each magnetic sheet is locally positioned around individual wires, providing tailored noise reduction for each conductor while preserving the specific spatial relationships and distances between wires that are necessary for optimal performance.
3Volume of moving object
If a grid-shaped magnetic body is wound around bundled wires, then the structure is compact, but it is difficult to accommodate wires of varying diameters and lengths
Solution Approach 1:
The magnetic body is segmented into multiple adjustable sheets that can be independently positioned around wires of different diameters and lengths. This segmentation provides the versatility to accommodate varying wire specifications while maintaining overall structural compactness through coordinated arrangement.
Solution Approach 2:
The magnetic sheets are designed with dynamic positioning capabilities, allowing adjustment to accommodate wires of varying diameters and lengths. This dynamic adaptability enables the compact structure to flexibly fit different wire configurations without compromising compactness.

AI summary
A noise reduction tool includes a sheet-like or belt-like magnetic body that can be wound. In the magnetic body, electric wires, axial directions of which are aligned with a winding axis direction of a winding shape, are disposed side by side around an axis of a winding axis on one plane disposed on the inner side in the winding shape. For example, in the magnetic body, an adhesive to be bonded to the other plane is provided on one plane of an end portion located on the outermost side of both end portions extending along the winding axis direction in the winding shape.
