Engineering Contradiction Analysis
1Area of stationary object
If multiple internal coil parts are disposed in an array-type inductor to decrease mounting area, then the area required for mounting is reduced, but harmful mutual interference of magnetic fields occurs leading to malfunction and efficiency deterioration
Solution Approach 1:
A spacer part made of non-magnetic material is introduced as an intermediary element positioned between adjacent internal coil parts. This spacer part physically separates the coil parts and prevents direct magnetic field coupling, thereby eliminating harmful mutual interference while maintaining the compact array-type structure. The spacer acts as a mediator that allows close spacing for miniaturization while blocking harmful magnetic interactions.
Solution Approach 2:
The magnetic body is segmented into multiple regions by inserting spacer parts between adjacent internal coil parts. This segmentation divides the continuous magnetic path into separate sections, preventing magnetic field lines from one coil part from directly coupling with adjacent coil parts. The segmentation strategy enables multiple coils to coexist in a compact space without harmful interactions.
2Object-affected harmful factors
If coil shapes and positions are adjusted to suppress magnetic field interference, then mutual interference is reduced, but the ability to adequately suppress interference during miniaturization is insufficient
Solution Approach 1:
The spacer part serves as a dedicated intermediary element that provides reliable magnetic field isolation without requiring complex coil shape modifications or precise positioning adjustments. This intermediary approach achieves effective interference suppression even in miniaturized configurations where traditional adjustment methods become insufficient.
Solution Approach 2:
By changing the material parameter of the spacer part to non-magnetic material, the magnetic field distribution and coupling characteristics are fundamentally altered. This parameter change enables effective interference suppression in compact designs where geometric adjustments alone cannot achieve sufficient isolation.
3Object-affected harmful factors
If spacer parts are disposed between internal coil parts with a predetermined interval, then harmful mutual interference is suppressed, but device complexity increases
Solution Approach 1:
The spacer part is designed with uniform cross-section and consistent material properties throughout, creating a homogeneous non-magnetic region between coil parts. This homogeneous design simplifies manufacturing and analysis while effectively maintaining magnetic field isolation. The simplicity of the homogeneous spacer structure offsets the added complexity of including multiple components.
Solution Approach 2:
The spacer part serves multiple functions simultaneously: it provides magnetic field isolation, maintains precise spacing between coil parts, provides structural support, and enables thermal management. This multi-functionality justifies the added structural element by eliminating the need for separate components for each function.
