Engineering Contradiction Analysis
1Reliability
If digital beamforming mode is used, then communication performance and flexibility are improved, but power consumption and device complexity increase
Solution Approach 1:
The patent implements dynamic switching between digital and analog beamforming modes based on real-time channel conditions and communication requirements. The system transitions from a static beamforming configuration to a dynamic one where the beamforming mode can be adjusted according to varying signal quality, data rate requirements, and power consumption constraints, thereby optimizing the trade-off between performance and energy usage.
Solution Approach 2:
The system changes the beamforming operational parameters by switching between different modes (digital vs. analog) based on measured channel conditions. When channel quality is good, the system may transition to analog beamforming to reduce power consumption, while in poor channel conditions, it switches to digital beamforming to maintain communication reliability, thus adapting parameters to environmental conditions.
2Reliability
If digital beamforming mode is used, then communication performance and flexibility are improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts beamforming complexity by switching modes based on communication needs. Instead of always employing complex digital beamforming, the system transitions to simpler analog beamforming when high performance is not required, thereby reducing device complexity and resource utilization while maintaining adequate communication quality.
Solution Approach 2:
The patent changes the operational parameters of the beamforming system by selecting between digital and analog modes. This parameter change allows the system to match computational complexity and hardware resource usage to the actual communication requirements, avoiding unnecessary complexity when simple beamforming suffices.
3Use of energy by moving object
If analog beamforming mode is used, then power consumption is reduced, but communication performance and flexibility decrease
Solution Approach 1:
The system implements dynamic mode selection where beamforming transitions between analog and digital based on real-time channel quality assessments. When channels are favorable, analog beamforming provides sufficient performance with lower power consumption. When channel conditions deteriorate, the system dynamically switches to digital beamforming to maintain communication reliability, thus adaptively balancing power efficiency and performance.
Solution Approach 2:
The system changes operational parameters by switching beamforming modes in response to channel conditions. This allows the system to optimize power consumption during good channel conditions while ensuring communication performance is maintained through digital beamforming when channel quality degrades, effectively adapting parameters to environmental variations.
4Productivity
If beamforming modes are switched frequently, then communication efficiency is optimized, but system stability and resource overhead increase
Solution Approach 1:
The system performs preliminary assessment of channel conditions and communication requirements before switching beamforming modes. By evaluating channel quality metrics and predicting future communication needs, the system avoids unnecessary mode transitions, thereby maintaining system stability while still optimizing communication efficiency when conditions warrant a change.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors channel conditions and communication performance metrics. Based on this feedback, mode switching decisions are made only when performance thresholds are crossed or significant channel changes are detected, preventing excessive switching and maintaining system stability while achieving optimal communication efficiency.
