Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measurement is performed under different temperature environments, then the structure can be evaluated under various operational conditions, but evaluation accuracy decreases due to uncorrected temperature influences
Solution Approach 1:
The patent applies parameter changes by introducing temperature as a correction parameter. The system changes the evaluation parameters based on temperature conditions, using temperature-specific correction values to adjust the elastic wave source location information. This allows the system to adapt to different temperature environments while maintaining evaluation accuracy through parameter adjustment.
Solution Approach 2:
The patent implements feedback by using temperature information to correct evaluation results. The system measures temperature, uses it to determine correction values, applies these corrections to the location information, and thereby improves evaluation accuracy. This feedback mechanism ensures that temperature influences are compensated for in the evaluation process.
2Measurement precision
If temperature correction is applied to improve evaluation accuracy, then measurement precision increases, but device complexity increases due to additional correction mechanisms
Solution Approach 1:
The patent applies preliminary action by pre-determining correction values for different temperature conditions. Instead of complex real-time calculations, the system uses pre-computed correction values that are applied based on measured temperature. This approach improves evaluation accuracy while avoiding the complexity of complex real-time correction algorithms.
