Engineering Contradiction Analysis
1Reliability
If a directional antenna is used to improve communication quality with a single terminal, then communication quality is improved, but it becomes difficult to determine appropriate antenna direction when multiple terminals are connected
Solution Approach 1:
The system acquires azimuth information and weighting coefficients from multiple terminals, calculates the optimal antenna direction based on this feedback, and adjusts the antenna direction accordingly. This closed-loop feedback mechanism enables automatic adaptation to multiple terminals while maintaining communication quality.
Solution Approach 2:
The system changes the antenna direction parameter based on calculated optimal values derived from terminal positions and weighting coefficients. By dynamically adjusting the antenna direction parameter, the system resolves the contradiction between maintaining high communication quality and adapting to multiple terminals.
2Reliability
If the antenna direction is fixed to serve one terminal, then communication with that terminal is stable, but communication range and adaptability to multiple terminals are reduced
Solution Approach 1:
The antenna direction is made dynamic rather than fixed. The system continuously calculates optimal directions based on terminal positions and weighting coefficients, allowing the antenna to adapt its direction dynamically to serve multiple terminals while maintaining stable communication with each.
Solution Approach 2:
The antenna system achieves multi-functionality by serving multiple terminals through calculated optimal directions. The same antenna can be directed to different terminals based on their respective weighting coefficients and positions, making the system universal across multiple communication scenarios.
3Adaptability or versatility
If the antenna direction is adjusted frequently to accommodate multiple terminals, then multi-terminal communication is improved, but system complexity and computational requirements increase
Solution Approach 1:
The wireless device performs self-service by automatically calculating optimal antenna directions using its own processing capabilities. The device acquires terminal information, computes weighting coefficients, determines optimal directions, and adjusts the antenna without external intervention, reducing system complexity.
Solution Approach 2:
The system performs preliminary calculations of weighting coefficients and optimal directions before actual communication adjustments. By pre-calculating these parameters based on terminal positions, the system simplifies the real-time decision-making process and reduces computational complexity during operation.
