Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spectral analysis methods are used to determine the origin of mixed gases and oils, then measurement precision can be achieved, but extensive calibration and large databases are required making the process inefficient and labor-intensive
Solution Approach 1:
The patent segments the complex spectral analysis problem into distinct topological features and characteristics that can be independently analyzed. By dividing the spectral data into manageable topological components, the method achieves accurate origin determination without requiring extensive calibration databases, thus resolving the contradiction between measurement precision and analysis efficiency
Solution Approach 2:
The patent replaces the conventional mechanical calibration-based spectral analysis system with a topological analysis system that uses mathematical topology to characterize spectral features. This substitution eliminates the need for extensive physical calibration samples while maintaining high measurement precision, thereby improving productivity without sacrificing accuracy
2Measurement precision
If extensive calibration with numerous standards is performed to improve origin determination accuracy, then measurement precision improves, but the complexity of the calibration process and database management increases
Solution Approach 1:
The patent extracts the essential topological characteristics from spectral data, separating the critical diagnostic features from the redundant information. By taking out only the necessary topological features needed for origin determination, the method maintains high measurement precision while significantly reducing calibration database complexity and management burden
Solution Approach 2:
The patent changes the parameter space from conventional spectral intensity values to topological descriptors that capture the essential shape and structure of spectral features. This parameter transformation enables accurate origin determination with fewer calibration standards, reducing both measurement precision loss and database complexity
3Productivity
If conventional spectral analysis is used with limited data availability, then the method can be applied with available samples, but the reliability of origin determination decreases due to nonlinear relationships and insufficient calibration data
Solution Approach 1:
The patent performs preliminary topological characterization of spectral features to extract invariant properties that are robust against variations in concentration and mixing ratios. By preparing these topological descriptors in advance, the method achieves reliable origin determination even with limited calibration data, maintaining both productivity and reliability
Solution Approach 2:
The patent uses simple topological descriptors that can be rapidly calculated from spectral data without requiring extensive calibration resources. These lightweight computational models provide reliable origin determination with minimal data requirements, enabling fast analysis while maintaining reliability even when calibration data is limited
