Engineering Contradiction Analysis
1Adaptability or versatility
If only one type of electromagnetic unit is used in the intelligent surface, then the device complexity is reduced and production costs are lowered, but the capability for manipulating spatial electromagnetic wave signals is insufficient
Solution Approach 1:
The patent applies local quality by dividing the intelligent surface into different regions with different electromagnetic unit types. Each region is equipped with electromagnetic units having specific geometric shapes and manipulation capabilities tailored to local requirements, enabling precise manipulation of electromagnetic wave signals in different spatial zones while maintaining overall system functionality
Solution Approach 2:
The patent employs composite materials principle by integrating multiple types of electromagnetic units (different geometric shapes, manipulation manners, and electromagnetic parameters) into a single intelligent surface system. This composite structure combines the advantages of various unit types to achieve superior electromagnetic wave manipulation capability compared to using a single type of unit
2Manufacturing precision
If multiple types of electromagnetic units are incorporated into the intelligent surface, then the manipulation precision of electromagnetic wave properties is improved, but the device complexity and production costs increase
Solution Approach 1:
The patent applies segmentation by dividing the intelligent surface into multiple modular units, each with specific functions for manipulating different electromagnetic wave properties (phase, amplitude, polarization direction, frequency). This modular segmentation enables precise manipulation of each property independently while allowing flexible configuration to achieve desired manipulation precision
Solution Approach 2:
The patent implements dynamics by making the intelligent surface reconfigurable through controllable electromagnetic units that can dynamically adjust their parameters (phase shift, amplitude modulation, polarization rotation, frequency adjustment) in real-time. This dynamic capability allows the system to adapt to different manipulation precision requirements for various application scenarios
