Engineering Contradiction Analysis
1Length of moving object
If a resonator element structure is used with changed parameters, then phase change can be achieved, but the maximum phase change is limited to 180° and the plate size is limited to about 1 cm
Solution Approach 1:
The radio wave refracting plate is divided into multiple unit structures, each containing resonators that can be independently configured. By segmenting the plate into repeating units with different resonator configurations, the overall plate can achieve larger size while maintaining controlled phase changes across different regions.
Solution Approach 2:
Different unit structures within the plate have different resonator configurations (different numbers of resonators per unit), creating local variations in phase change characteristics. This allows different regions of the plate to contribute differently to the overall phase control, enabling phase changes beyond 180° while supporting larger plate dimensions.
2Area of stationary object
If the plate size is increased beyond 1 cm, then larger coverage area is achieved, but the phase change capability is restricted due to the 180° limitation
Solution Approach 1:
The plate is segmented into multiple unit structures that can be arranged in arrays. Each unit structure contributes a controlled phase change, and by combining multiple units with different configurations, the overall plate achieves both large area and reliable refraction performance through cumulative phase control.
Solution Approach 2:
The invention changes the parameter of resonator configuration within unit structures (specifically the number of resonators per unit) to achieve different phase changes. This parameter variation allows the plate to maintain reliable refraction performance across larger areas by adjusting the local resonator configurations in different unit structures.
3Adaptability or versatility
If more resonators are added to increase phase change capability, then phase control is improved, but the device complexity increases
Solution Approach 1:
The resonators are organized into discrete unit structures with specific configurations (e.g., 0, 1, or 2 resonators per unit). This segmentation allows phase change capability to be achieved through simple combinatorial arrangements of standardized units, rather than requiring complex continuous variations, thereby improving adaptability while controlling device complexity.
