Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed voltage generators are used, then the device structure is simple, but the RF circuit performance cannot be optimized and voltage levels are fixed
Solution Approach 1:
The patent implements dynamic voltage generation by using RF signal power to control the switching state of transistors in the voltage generation circuit. The voltage output level changes dynamically based on the RF signal strength, allowing the voltage generator to adapt to different operating conditions rather than being fixed at a single level.
Solution Approach 2:
The patent changes the voltage output parameter based on RF signal power levels. The voltage generation circuit responds to variations in RF signal strength by adjusting the output voltage magnitude, enabling the system to optimize performance across different signal conditions through parameter adaptation.
2Object-affected harmful factors
If conventional voltage generators are used, then the circuit design is simple, but harmonics generated by RF signals are not suppressed
Solution Approach 1:
The patent converts the harmful harmonic signals into useful information by using them to control the voltage generation circuit. The harmonics generated by RF signals are detected and used to adjust the voltage output, transforming what would normally be interference into a control mechanism that optimizes circuit performance and suppresses unwanted effects.
Solution Approach 2:
The patent introduces an intermediary voltage generation circuit that sits between the RF signal source and the rest of the system. This intermediate circuit processes the RF signal and its harmonics, using them to modulate the voltage output in a way that suppresses harmonic interference while providing appropriate voltage levels for circuit operation.
3Reliability
If fixed voltage levels are provided, then the voltage generator is simple to design, but the RF circuit cannot achieve optimal performance
Solution Approach 1:
The patent implements a feedback mechanism where the RF signal power level is continuously monitored and used to adjust the voltage generation output. The voltage generator responds to changes in RF signal strength by automatically adjusting its output voltage, creating a closed-loop system that optimizes RF circuit performance based on real-time signal conditions.
