Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full duplex mode is used to improve spectrum utilization, then spectral efficiency is improved, but communication quality deteriorates under poor channel conditions due to self-interference
Solution Approach 1:
The patent implements dynamic duplex mode adaptation by continuously monitoring channel conditions (signal-to-noise ratio, interference levels) and switching between full duplex and non-full duplex modes. This dynamic adjustment allows the system to maximize spectral efficiency when channel conditions are good while maintaining communication quality when conditions deteriorate, thereby resolving the contradiction between productivity and reliability.
Solution Approach 2:
The system changes operational parameters (duplex mode, modulation scheme, power levels) based on measured channel conditions. By adjusting these parameters dynamically, the system optimizes spectral efficiency during favorable conditions while preventing communication quality degradation during poor conditions, thus resolving the technical contradiction.
2Quantity of substance
If full duplex mode is used to increase system capacity, then bandwidth utilization is improved, but signal attenuation under poor weather conditions causes self-interference to dominate, reducing system capacity
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously measures channel conditions including signal-to-noise ratio and interference levels. Based on this feedback, the system determines whether to operate in full duplex or non-full duplex mode. This feedback-driven adaptation allows the system to increase capacity when self-interference is manageable while avoiding capacity reduction when self-interference becomes dominant under poor weather conditions.
Solution Approach 2:
The system dynamically adjusts its operational mode based on real-time channel conditions. When weather conditions are good and self-interference is low, full duplex mode maximizes system capacity. When weather conditions deteriorate and self-interference increases, the system switches to non-full duplex mode to maintain stable operation, thus resolving the contradiction between quantity and harmful factors.
3Device complexity
If duplex mode is fixed to maintain system simplicity, then device complexity is reduced, but adaptability to varying channel conditions deteriorates
Solution Approach 1:
The patent implements dynamic duplex mode selection that adapts to varying channel conditions. The system monitors signal quality metrics and automatically switches between full duplex and non-full duplex modes, providing adaptability to different weather and channel conditions while maintaining manageable system complexity through automated decision-making algorithms.
Solution Approach 2:
The system performs self-adjustment by automatically monitoring channel conditions and selecting the appropriate duplex mode without requiring manual intervention. This self-service capability provides adaptability to varying conditions while keeping the control mechanism relatively simple, as the system makes decisions based on pre-defined thresholds and algorithms.
