Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex optimization algorithms are used to optimize antenna performance, then performance parameters can be improved, but the system complexity and computational requirements increase significantly
Solution Approach 1:
The patent uses simple, inexpensive scattering elements made of basic conductive materials (copper, aluminum, or conductive polymer) that can be easily manufactured and replaced. These elements achieve effective antenna optimization without requiring complex computational algorithms, thereby resolving the contradiction between performance and complexity by substituting expensive complex algorithms with cheap physical structures
Solution Approach 2:
The antenna system performs self-optimization through the physical arrangement and electromagnetic interaction of scattering elements with the antenna body. The scattering elements automatically adjust the electromagnetic field distribution based on their geometric configuration and material properties, eliminating the need for external complex optimization algorithms while maintaining high performance
2Adaptability or versatility
If traditional antenna designs are used, then manufacturing is simpler, but adaptability to different performance requirements is limited
Solution Approach 1:
The antenna is divided into a traditional antenna body and separate, discrete scattering elements that can be independently designed, manufactured, and positioned. This segmentation allows the scattering elements to be optimized for specific performance requirements (gain, beamwidth, polarization) without redesigning the entire antenna system, thereby achieving high adaptability while maintaining relatively simple overall structure
Solution Approach 2:
Different scattering elements are designed with specific local properties (shape, size, material, position) tailored to achieve particular electromagnetic functions. Each scattering element can be optimized for its specific role in the overall antenna performance, enabling versatile adaptation to different performance requirements while keeping the base antenna structure simple and manufacturable
