Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are used to form various beams for adaptive communication, then the adaptability and network capacity are improved, but the device complexity increases due to the need for dynamic connection management and phase control
Solution Approach 1:
The patent implements dynamic beam formation by enabling switches to dynamically connect different antenna groups to different RF signal sources based on communication requirements. The system can adaptively reconfigure antenna connections in real-time to form beams toward different directions, allowing the same physical antenna structure to serve multiple communication functions without physical movement.
Solution Approach 2:
The patent divides the antenna system into multiple separable antenna groups (first antenna group and second antenna group) that can be independently connected to different RF signal sources. This segmentation allows flexible combination and reconfiguration of antenna elements to form different beam patterns, simplifying the control logic by managing smaller antenna subsets rather than the entire array simultaneously.
2Reliability
If physical antenna movement is avoided, then the device structure is simplified and reliability is improved, but the ability to adapt to changing wireless environments is reduced
Solution Approach 1:
The patent replaces the mechanical antenna movement system with an electrical reconfiguration system. Instead of physically moving antennas to change beam direction, the system uses electronic switches and phase control to dynamically reconfigure the antenna connections and signal phases, achieving beam steering purely through electrical means. This eliminates mechanical wear and failure points while maintaining environmental adaptability.
Solution Approach 2:
The patent achieves beam direction control by changing electrical parameters (connection configurations and phase shifts) rather than physical position. By adjusting the phase of RF signals and the connection state of switches, the system can steer beams in different directions without moving the antennas, thus improving reliability while preserving adaptability to changing wireless environments.
