Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple inductors and capacitors with varying values are used to adjust resonant frequencies, then resonant frequency adaptability is improved, but device complexity and size increase
Solution Approach 1:
The patent changes the operating parameters of existing inductor and capacitor components by dynamically adjusting their effective values through switching arrangements. Instead of using multiple physical components with different values, the system varies the parameters of single components by controlling which portions are active, thereby achieving frequency adaptability without increasing component count
Solution Approach 2:
The patent introduces dynamic switching mechanisms that allow the inductor and capacitor values to be adjusted in real-time during operation. The switching arrangement enables the system to transition between different resonant frequencies by dynamically reconfiguring the active portions of the inductor and capacitor, replacing static multiple-component solutions with a dynamic single-component approach
2Adaptability or versatility
If multiple inductors and capacitors with varying values are used to adjust resonant frequencies, then resonant frequency adaptability is improved, but device size increases
Solution Approach 1:
The patent merges the functions of multiple inductors and capacitors with different values into single inductor and capacitor components. By using switching arrangements to select different effective portions of these single components, the system achieves the functionality of multiple components while occupying the space of only one inductor and one capacitor, thereby reducing overall device size
3Adaptability or versatility
If resonant frequency is changed using selectively switched in devices, then frequency calibration capability is improved, but the number of required devices increases
Solution Approach 1:
The patent segments the inductor and capacitor into multiple effective portions that can be selectively activated. Instead of using multiple complete inductor and capacitor devices, the system divides each component into segments and uses switching arrangements to activate only the necessary portions, achieving frequency calibration capability while minimizing the total number of devices required
