Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dielectric lenses are used to control electromagnetic waves, then radio wave control is achieved, but performance consistency across wide frequency band deteriorates
Solution Approach 1:
The reflective plate is divided into multiple unit structures, each containing resonators that can be independently designed with specific resonance frequencies. This segmentation allows different frequency ranges to be handled by different unit structures, achieving wide frequency band coverage while maintaining consistent performance through optimized local resonance characteristics
Solution Approach 2:
The resonance frequencies of the resonators are adjusted by changing geometric parameters such as the width, length, and shape of the resonating portions. By optimizing these parameters, the resonators can be tuned to specific frequency ranges, enabling consistent performance across different frequency bands while maintaining adaptability
2Ease of operation
If resonator parameters are changed to control radio waves, then radio wave refraction is achieved, but frequency stability deteriorates
Solution Approach 1:
The unit structures are designed with resonators that have fixed geometric parameters optimized for specific frequency ranges. This dynamic design allows the structures to naturally resonate at predetermined frequencies, providing frequency stability while maintaining the ability to control radio waves through resonant enhancement at target frequencies
3Adaptability or versatility
If unit structures with multiple resonators are used, then frequency adjustment capability is improved, but device complexity increases
Solution Approach 1:
The complex frequency control function is segmented into multiple simple resonator units, each responsible for a specific frequency range. By arranging these segmented resonators in arrays, the system achieves wide frequency adjustment capability while keeping each individual unit structurally simple and easy to manufacture
Solution Approach 2:
The unit structures are designed with universal configurations where resonators of different geometries can be used to cover different frequency ranges. This multi-functionality allows the same basic unit structure to serve multiple frequency adjustment purposes, reducing overall device complexity while maintaining versatility
