Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of antenna elements are combined to control designated directions of antenna beams, then beam directionality is improved, but the arrangement area of the antenna structure is greatly enlarged
Solution Approach 1:
The antenna structure is divided into multiple antenna units, each with independent feeding ports. By segmenting the antenna into modular units with i feeding ports each, the system achieves beam directionality control without requiring a large number of separate antenna elements, thus reducing the overall arrangement area while maintaining adaptability.
Solution Approach 2:
The patent implements dynamic control of feeding port vectors to adjust beam directions. By dynamically configuring the vectors of feeding ports in each antenna unit according to designated directions, the system can control beam directionality adaptively without enlarging the physical antenna structure, resolving the contradiction between versatility and area.
2Adaptability or versatility
If conventional antenna designs are used to control designated directions, then beam directionality is achieved, but polarization loss occurs due to mismatched polarized directions
Solution Approach 1:
Each antenna unit is designed with multi-functional capability to handle multiple polarized directions. By incorporating i feeding ports with independently controllable vectors in each antenna unit, the system can adapt to different polarization requirements and achieve beam directionality control without polarization loss, as the antenna can match the polarized direction of incoming electromagnetic waves.
Solution Approach 2:
The patent changes the parameters of feeding port vectors to optimize performance. By independently controlling the vectors of feeding ports and adjusting their parameters according to designated directions, the system can match polarized directions and eliminate polarization loss while maintaining beam directionality control.
3Area of stationary object
If antenna size is reduced for compact electronic devices, then adaptability to compact design is improved, but antenna effect may be compromised
Solution Approach 1:
The patent applies local quality by optimizing each antenna unit with i feeding ports to have superior local performance. Each antenna unit is designed with high-quality independent vector control capabilities, allowing compact antenna size while maintaining or improving overall antenna effect through the enhanced performance of individual units.
Solution Approach 2:
The antenna structure uses a composite approach by combining multiple antenna units with independent feeding port systems. This composite structure allows the overall antenna to be compact while each component unit contributes to maintaining strong antenna effect, achieving both small size and high reliability.
