Engineering Contradiction Analysis
1Device complexity
If power line communication is used for data transmission, then space and cost are saved by using the supply line simultaneously as data line, but data transmission reliability deteriorates due to voltage fluctuations affecting signal stability
Solution Approach 1:
The patent implements dynamic parameter adjustment by continuously monitoring voltage fluctuations and adapting the modulation scheme in real-time. The system switches between different communication modes (e.g., frequency shift keying, amplitude shift keying) based on current voltage stability conditions, allowing reliable data transmission despite power line voltage variations.
Solution Approach 2:
The patent changes communication parameters such as modulation depth, baud rate, and threshold levels according to the measured voltage fluctuation magnitude. When voltage stability is high, higher data rates are used; when volatility increases, the system reduces data rate or switches to more robust modulation schemes to maintain transmission reliability.
2Reliability
If voltage stabilization measures are implemented to improve signal stability, then data transmission reliability is improved, but technical complexity and cost increase
Solution Approach 1:
The patent implements self-service by having the communication system automatically monitor voltage conditions and adjust its own transmission parameters without external intervention. The system includes built-in voltage sensing and adaptive modulation capabilities that allow it to self-regulate and maintain reliable communication without additional stabilization hardware.
Solution Approach 2:
The patent employs feedback mechanisms where the received signal quality is continuously monitored and used to adjust transmission parameters. The system measures voltage fluctuations during communication and feeds this information back to the transmitter, which then adapts its modulation scheme or power level to compensate for the observed variations, maintaining signal stability without complex external stabilization.
