Engineering Contradiction Analysis
1Ease of operation
If visual inspection method is used for electromagnetic immunity testing, then the testing process is simple and easy to implement, but the analysis precision and reliability are insufficient for high-speed, high-reliability, and high-precision numerical control systems
Solution Approach 1:
The patent replaces the manual visual inspection method with an automated data acquisition and control system that uses sensors, data acquisition cards, and computer software to automatically collect and analyze position data during electromagnetic immunity testing, thereby improving measurement precision while maintaining operational simplicity
Solution Approach 2:
The patent introduces a data acquisition card and computer system as intermediaries between the numerical control system and the tester, enabling automatic data collection and quantitative analysis of electromagnetic immunity effects, which resolves the contradiction between simple testing process and precise analysis
2Measurement precision
If quantitative analysis system is implemented for electromagnetic immunity testing, then the analysis precision and reliability are improved, but the device complexity increases
Solution Approach 1:
The patent designs a multi-functional data acquisition and control system that can perform multiple functions including position data collection, electromagnetic signal generation, data processing, and quantitative analysis within a single integrated platform, thereby reducing overall device complexity while maintaining high measurement precision
Solution Approach 2:
The system implements automated data collection, processing, and analysis functions that operate autonomously without requiring complex manual intervention, allowing the system to serve itself in data acquisition and processing tasks, thus improving precision without proportionally increasing complexity
