Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent antennas are used to support various functions, then the functional versatility is improved, but the device volume increases
Solution Approach 1:
The patent implements a sleeving arrangement where at least two antennas are arranged in sequence with adjacent antennas partially sleeving each other. Specifically, one antenna is positioned inside the projection area of another antenna along the thickness direction, creating a nested configuration that significantly reduces the overall device volume while maintaining multiple antenna functions for diverse communication capabilities
2Adaptability or versatility
If multiple independent antennas are arranged in sequence, then the functional versatility is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple antenna structures into a compact antenna cluster where adjacent antennas are partially overlapped in the thickness direction. This merging approach integrates multiple functional antennas into a unified cluster structure, reducing device complexity compared to using completely independent antennas while maintaining functional versatility through the feed structure's ability to selectively activate different antennas
