Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of test signal parameters is used, then the test device can be simpler in structure, but the testing process becomes cumbersome and time-consuming
Solution Approach 1:
The patent implements automated feedback loops that continuously monitor test parameters and automatically adjust the test signal characteristics based on measured results. This eliminates manual adjustment while maintaining simple device structure, resolving the contradiction between device simplicity and testing efficiency
Solution Approach 2:
The test device performs self-adjustment of test parameters through automated control systems that modify test signal frequency, amplitude, and waveform characteristics without operator intervention. This enables the device to serve itself, reducing both structural complexity and testing time
2Adaptability or versatility
If multiple variable factors are present in the test device, then the test device can simulate real-world conditions better, but the test results become inconsistent due to variations
Solution Approach 1:
Automated feedback mechanisms monitor and compensate for variations in test parameters, maintaining consistent test results even when simulating diverse real-world conditions. The system measures output voltage variations and automatically adjusts test parameters to maintain precision across different test scenarios
Solution Approach 2:
The patent systematically varies test parameters such as load current, switching frequency, and waveform characteristics while maintaining controlled conditions through automated regulation. This enables versatile simulation of real-world operating conditions while preserving measurement precision through parameter control
3Measurement precision
If automated control and feedback loops are implemented, then the testing process becomes more precise and consistent, but the device complexity increases
Solution Approach 1:
The patent employs universal control modules and integrated circuits that perform multiple functions including signal generation, parameter adjustment, and measurement. This multi-functionality reduces the number of separate components needed, achieving automated precise control without proportionally increasing device complexity
Solution Approach 2:
The test device combines multiple control functions and measurement capabilities into integrated circuits and combined signal paths. By merging functions that would traditionally require separate components, the system achieves high measurement precision while limiting the increase in overall device complexity
