Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single-layer inductor is used, then the structure is simple, but the applicability is limited to one-way input or output and the space occupied is large
Solution Approach 1:
The patent transitions from a conventional single-layer planar structure to a multi-layer three-dimensional structure by adding extension portions that extend in different directions (first direction and second direction). This dimensional change enables multiple input and output terminals while compacting the overall footprint, thereby increasing adaptability without proportionally increasing occupied space
Solution Approach 2:
The inductor structure is segmented into multiple functional portions: first extension portion, second extension portion, third extension portion, fourth extension portion, and fifth extension portion. Each portion serves specific input/output functions, allowing the inductor to handle multiple signals simultaneously. This segmentation enables versatile connectivity while maintaining a compact integrated structure
2Power
If a larger inductor is used to achieve better performance, then the inductive effect is improved, but the space consumed in the power product increases
Solution Approach 1:
The patent employs a nested arrangement where extension portions are integrated within the overall inductor structure. The first, second, third, fourth, and fifth extension portions are arranged in a compact nested configuration that maximizes the inductive effect within a minimized footprint, allowing strong inductive performance without proportional space increase
3Adaptability or versatility
If a multi-layer coil structure with extension portions is used, then multiple inputs and outputs are achieved and space is reduced, but the structural complexity increases
Solution Approach 1:
The patent merges multiple functional extension portions into a single integrated inductor body. The first extension portion, second extension portion, third extension portion, fourth extension portion, and fifth extension portion are combined in one cohesive structure, achieving multiple inputs and outputs without requiring separate discrete components, thus managing complexity through integration
