Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single antenna element is used, then the device complexity is reduced, but the scan-angle coverage and adaptability are insufficient
Solution Approach 1:
The antenna system is divided into multiple antenna elements (first antenna element and second antenna element) with different radiation patterns. The first antenna element provides wide scan-angle coverage while the second antenna element provides focused beam coverage, together achieving comprehensive angular coverage without requiring a single complex antenna structure
Solution Approach 2:
The radiation pattern of the first antenna element is configured to be adjustable, allowing dynamic adaptation to different communication scenarios. This adjustability enables the system to optimize beam direction and coverage area based on real-time requirements, enhancing versatility without permanently increasing structural complexity
2Adaptability or versatility
If the radiation pattern is made adjustable, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The radiation pattern adjustment is achieved by changing electromagnetic parameters (amplitude and phase) of the signals fed to different antenna elements through the processing unit. This parameter-based control allows flexible radiation pattern adjustment without mechanical moving parts or complex physical structures, reducing overall device complexity while maintaining high adaptability
3Adaptability or versatility
If multiple antenna elements are added, then the scan-angle coverage is improved, but the package size increases
Solution Approach 1:
Multiple antenna elements with different radiation patterns are integrated into a single antenna assembly mounted on one surface of the supporting element. The first and second antenna elements work together in a unified structure, achieving wide scan-angle coverage without proportionally increasing the overall package area
Solution Approach 2:
The patent utilizes spatial arrangement of antenna elements in three-dimensional space on the supporting element surface. By positioning elements at different locations and orientations, the system achieves comprehensive angular coverage through spatial diversity rather than simply increasing the two-dimensional footprint area
