Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single 8-shaped coil is used, then the device structure is simple, but magnetic field bias occurs and inductive efficiency is reduced
Solution Approach 1:
The inductive device is segmented into two separate 8-shaped coils (first and second coils) disposed side by side, with each coil forming an independent loop. This segmentation allows each coil to contribute symmetrically to the magnetic field, eliminating the magnetic field bias that occurs in single asymmetric 8-shaped coils while maintaining structural simplicity.
2Ease of manufacture
If asymmetric coil structure is used, then manufacturing is easier, but magnetic cancellation is unbalanced and noise increases
Solution Approach 1:
The invention employs symmetric arrangement of two 8-shaped coils side by side, where each coil is individually symmetric and their combined configuration creates balanced magnetic fields. This symmetric design ensures that magnetic fields from corresponding segments of each coil cancel each other effectively, reducing magnetic noise while maintaining ease of manufacture through standardized coil fabrication.
3Use of energy by moving object
If coil size is increased to improve coupling, then induction coupling effects are enhanced, but circuit volume increases
Solution Approach 1:
The two 8-shaped coils are merged into a single integrated inductive device structure, disposed side by side to form a compact configuration. This merging approach enhances induction coupling effects through the combined magnetic fields of both coils while maintaining a compact overall volume, as the coils share the same space rather than requiring separate volumes.
