Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a conventional signal processing circuit is used to control reactance, then the circuit structure is simple, but the time to achieve maximum electric field amplitude is prolonged and power consumption increases
Solution Approach 1:
The patent implements dynamic reactance control by switching between different reactance values based on detected electric field amplitude. The control circuit dynamically adjusts the reactance section configuration (series/parallel switching) to optimize electric field amplitude, transitioning from static to dynamic control to reduce the time to achieve maximum amplitude.
Solution Approach 2:
The patent employs a feedback mechanism where the electric field amplitude is detected and used to control the reactance adjustment. The detection circuit monitors the amplitude and provides feedback signals to the control circuit, which then adjusts the reactance accordingly, creating a closed-loop system that accelerates convergence to maximum amplitude.
2Productivity
If reactance is adjusted to maximize electric field amplitude, then data communication efficiency improves, but power consumption increases
Solution Approach 1:
The patent implements periodic reactance adjustment cycles rather than continuous adjustment. The control circuit periodically switches between different reactance configurations and measures the resulting electric field amplitude, allowing the system to achieve optimal communication efficiency while reducing continuous power consumption through intermittent operation.
Solution Approach 2:
The patent applies partial adjustment of reactance by switching between discrete reactance values rather than continuous adjustment. This partial action approach achieves sufficient electric field amplitude for effective communication while consuming less power than full continuous optimization would require.
3Reliability
If multiple reactance values are tested to find the optimal value, then electric field amplitude is maximized, but the adjustment time increases
Solution Approach 1:
The patent applies preliminary action by pre-setting multiple discrete reactance values that are likely to include the optimal value. Instead of searching through all possible values, the system pre-configures a limited set of reactance options, allowing rapid switching and testing to find the optimal value without exhaustive search.
Solution Approach 2:
The patent implements dynamic switching between pre-set reactance values based on real-time detection results. The control circuit dynamically selects from multiple pre-configured reactance options, adjusting the configuration based on detected electric field amplitude to quickly identify and lock onto the optimal value.
