Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed coil structure is used, then the inductor provides a stable inductance value, but the inductance value cannot be adjusted or varied
Solution Approach 1:
The coil is divided into multiple independent coil sections (first coil section, second coil section, third coil section, fourth coil section) that can be selectively connected through switching circuits. This segmentation allows the inductor to provide different inductance values by activating different combinations of coil sections, thereby achieving inductance adjustability without requiring a completely different coil structure for each inductance value.
Solution Approach 2:
The patent introduces route switching circuits that can dynamically change the connection configuration between coil sections based on control signals. The switching circuits enable the inductor to transition between different operating modes (first mode, second mode, third mode, fourth mode, fifth mode) with different inductance values, making the inductance value dynamic and adjustable rather than fixed.
2Adaptability or versatility
If multiple coil sections with switching circuits are implemented, then variable inductance values are achieved, but the device complexity increases
Solution Approach 1:
The route switching circuits are designed to perform multiple functions: they selectively connect different coil sections, control the signal transmission paths, and determine the overall inductance value of the inductor. This multi-functionality reduces the need for separate control mechanisms for each coil section, thereby managing the complexity of the switching circuit while achieving variable inductance values through a unified control approach.
3Ease of operation
If route switching circuits are added to enable inductance adjustment, then inductance control is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent combines multiple coil sections and switching circuits into a single integrated inductor structure. The coil sections are positioned in close proximity and the switching circuits are integrated within the same device, allowing for combined fabrication processes. This merging approach enables the entire variable inductor to be manufactured as a single integrated component rather than assembling separate discrete components, thereby reducing manufacturing complexity despite the increased functional complexity.
