Engineering Contradiction Analysis
1Measurement precision
If multiple tuning algorithms are used to control different circuit components, then the tuning precision and performance optimization are improved, but the device complexity and control difficulty increase
Solution Approach 1:
The patent divides the tuning control into multiple independent algorithms, each responsible for a specific circuit component (impedance matching network, reactive elements, amplifier, filter). This segmentation allows each algorithm to focus on optimizing a particular component without being overwhelmed by the complexity of the entire system, thereby maintaining high tuning precision while managing control complexity through modular organization.
Solution Approach 2:
The patent implements dynamic execution control where the order and activation of tuning algorithms are adjusted based on operational conditions. The system determines when to execute each algorithm and when to pause others, creating a dynamic control structure that adapts to different operating scenarios. This dynamic approach allows the system to maintain precision across varying conditions while reducing instantaneous control complexity by not all algorithms running simultaneously.
2Productivity
If multiple circuit components are tuned simultaneously, then the overall system performance is improved, but the stability and convergence of tuning algorithms deteriorate
Solution Approach 1:
The patent employs periodic execution of tuning algorithms in structured sequences rather than continuous simultaneous operation. The system organizes algorithm execution into periodic cycles where different algorithms are activated in turns based on the operational phase. This periodic structure allows each algorithm to complete its convergence process before the next one begins, maintaining tuning stability while achieving overall system performance optimization through repeated cycling through all components.
Solution Approach 2:
The patent implements feedback mechanisms where the execution state and convergence status of each tuning algorithm are continuously monitored. Based on this feedback, the system dynamically adjusts the execution order and timing of subsequent algorithms. When one algorithm achieves stability, it triggers the next phase of tuning. This feedback-driven control ensures that simultaneous tuning operations do not interfere with each other's convergence, maintaining stability while achieving comprehensive system performance improvement.
3Productivity
If tuning algorithms are executed in parallel, then the tuning speed and productivity are improved, but the resource consumption and computational load increase
Solution Approach 1:
The patent implements dynamic resource allocation where computational resources are allocated to tuning algorithms based on real-time needs and operational context. Rather than dedicating fixed resources to each algorithm, the system dynamically adjusts processing power and memory allocation according to which algorithms are currently active and their convergence progress. This dynamic resource management enables faster tuning when resources are available while reducing computational load during resource-constrained periods, achieving a balance between tuning speed and resource consumption.
