Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional data processing methods are used in chromatographic mass spectrometry systems, then data processing can be performed with simple algorithms, but the system retains large amounts of noise and unwanted information
Solution Approach 1:
The patent segments the complex data processing task into multiple distinct modules: data acquisition, preprocessing (baseline correction, smoothing), feature detection (peak identification), factor analysis (PCA, ICA), and result generation. Each module handles a specific aspect of noise reduction and signal extraction, making the overall complex system manageable and effective.
Solution Approach 2:
The patent introduces intermediate processing steps between raw data acquisition and final results. Preprocessing operations (baseline correction, smoothing filters) act as intermediaries to condition the data before analysis. Factor analysis serves as an intermediary technique that transforms complex spectral data into meaningful chemical information while filtering noise.
2Measurement precision
If advanced processing techniques are applied to reduce noise, then the accuracy of differentiating relevant information from noise improves, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary preprocessing operations (baseline correction, smoothing, normalization) on the entire dataset before detailed analysis. This preliminary action prepares the data in advance, making subsequent factor analysis and peak detection more efficient and accurate, reducing overall processing time despite the added initial steps.
Solution Approach 2:
The patent employs multiple factor analysis methods (PCA, ICA, MCR) with adjustable parameters and thresholds. By optimizing these parameters based on data characteristics, the system achieves high accuracy in noise differentiation while controlling processing time through efficient algorithm selection and parameter tuning.
3Manufacturing precision
If multiple factor analysis methods are used to process chromatographic data, then the resolution and accuracy of results improve, but the device complexity and processing requirements increase
Solution Approach 1:
The patent implements a universal data processing framework that can accommodate multiple factor analysis methods (PCA, ICA, MCR) within a single integrated system. This multi-functional approach allows the same processing pipeline to handle different data types and analysis requirements, achieving high resolution through method selection rather than requiring separate dedicated systems for each technique.
