Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antenna designs are used in high-frequency bands, then device integration is simplified, but communication performance and gain are insufficient
Solution Approach 1:
The patent combines multiple antenna elements (first antenna with first radiator and second antenna with second radiator) into a single integrated antenna assembly. The conductive plates are merged with the support member to form integrated radiating structures, achieving high-frequency communication performance while maintaining compact device integration through unified design rather than separate components
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning the first and second antennas at different locations and orientations within the device housing. The radiators extend in different directions (first direction and second direction perpendicular to each other), creating multi-dimensional beam coverage and achieving wide coverage in high-frequency bands through spatial diversity
2Adaptability or versatility
If antenna elements are added to improve beam coverage, then communication coverage increases, but device complexity increases
Solution Approach 1:
The antenna assembly is designed to provide multiple functions through a unified structure. The same antenna assembly supports both first and second antennas with different polarizations and orientations, enabling the system to handle multiple communication standards and beam directions simultaneously. The conductive plates serve dual purposes as both structural support and radiating elements
Solution Approach 2:
The antenna assembly is segmented into distinct functional modules - the first antenna module with its conductor plate and radiator for one polarization direction, and the second antenna module with its conductor plate and radiator for the perpendicular polarization direction. This segmentation allows independent optimization of each antenna element while maintaining overall system integration through the shared support member
