Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power line carrier communication is used to transmit communication signals on power lines, then communication capability is provided, but noise interference from power lines degrades communication quality
Solution Approach 1:
The patent implements dynamic channel switching by continuously monitoring signal noise levels on different power line channels and automatically switching to channels with lower noise levels. This dynamic adaptation allows the communication system to respond to changing noise conditions in real-time, maintaining communication quality despite the inherently noisy power line environment.
Solution Approach 2:
The system changes the operational parameter of the communication channel by switching between different power line channels based on their noise characteristics. By selecting channels with optimal signal-to-noise ratios, the system adapts to varying noise conditions while maintaining communication capability.
2Power
If three-phase power supply is used to supply power to equipment, then power delivery is achieved, but signal coupling between phases causes noise interference across multiple channels
Solution Approach 1:
The patent implements dynamic channel selection that adapts to noise patterns caused by three-phase power coupling. By continuously monitoring noise levels on different phases and switching to quieter channels, the system mitigates the harmful effects of inter-phase signal coupling while maintaining power supply functionality.
Solution Approach 2:
The channel switching mechanism acts as an intermediary that selects optimal communication paths through the power line network. By routing communication signals through channels with minimal interference from three-phase coupling, the system separates the power delivery function from the communication function, reducing mutual interference.
3Reliability
If channel switching is implemented to avoid noise interference, then communication quality is improved, but system complexity increases
Solution Approach 1:
The patent implements a self-service channel switching mechanism where the system automatically monitors noise levels and performs channel switching without external intervention. The communication device itself detects noise conditions and executes switching decisions, eliminating the need for complex external control systems while maintaining high communication quality.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring signal noise levels on available channels and using this information to make intelligent switching decisions. This feedback-driven approach enables automatic adaptation to noise conditions, improving communication reliability without requiring complex predetermined control logic.
