Engineering Contradiction Analysis
1Productivity
If multi-antennas are used to improve transmission data rate, then transmission data rate is improved, but mutual interference between antennas increases
Solution Approach 1:
The patent implements dynamic switching between different antenna units based on real-time performance evaluation. The system continuously monitors antenna performance metrics and dynamically selects the optimal antenna configuration, transforming the static multi-antenna system into a dynamic one that adapts to changing conditions, thereby maintaining high data rates while minimizing interference.
Solution Approach 2:
The system changes operational parameters by switching between different antenna units with varying characteristics. Each antenna unit has different radiation patterns, gain, and interference characteristics. By selecting antennas based on current performance parameters, the system optimizes the trade-off between transmission data rate and mutual interference.
2Device complexity
If fixed single frequency operation is used, then device complexity is reduced, but adaptability to different environments deteriorates
Solution Approach 1:
The patent introduces dynamic environmental adaptation through continuous performance evaluation and antenna switching. The system monitors communication quality and environmental conditions, then dynamically selects the most suitable antenna unit, enabling the fixed single-frequency system to adapt to varying environments without increasing operational complexity.
Solution Approach 2:
The system performs self-adjustment by automatically evaluating antenna performance and switching between units based on environmental conditions. The performance evaluation module continuously monitors system state and triggers antenna switching without external intervention, allowing the system to self-optimize for different environments while maintaining simple fixed-frequency operation.
3Reliability
If antenna performance is continuously monitored and switched, then system performance is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic performance evaluation mechanism that continuously monitors antenna metrics such as signal strength, interference level, and radiation pattern. Based on real-time performance data, the system dynamically switches between antenna units, achieving high reliability through adaptive selection while managing complexity through automated decision-making algorithms.
Solution Approach 2:
The system employs feedback control by continuously evaluating antenna performance and using this information to drive switching decisions. The performance evaluation module provides feedback on antenna effectiveness, and this feedback loop enables the system to maintain optimal communication quality by selecting the best-performing antenna unit at any given time.
