Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional extraction and chromatography methods are used to determine fatty acid profiles, then measurement precision is improved, but loss of time and productivity are worsened
Solution Approach 1:
The patent replaces mechanical extraction and chromatographic separation methods with Fourier transform infrared spectroscopy (FTIR), an optical/spectroscopic method. This substitution eliminates time-consuming extraction, hydrolysis, and separation steps while providing rapid fatty acid profile determination through direct spectral analysis of seed samples.
Solution Approach 2:
The patent uses FTIR spectroscopy to obtain a spectral fingerprint copy of the seed's fatty acid composition without physically extracting or destroying the sample. The infrared spectrum serves as an information copy that contains all necessary data for fatty acid profile determination, enabling rapid analysis while preserving the original seed.
2Measurement precision
If extraction methods are used to analyze fatty acids, then measurement precision is improved, but seeds are destroyed
Solution Approach 1:
The patent replaces destructive mechanical and chemical extraction methods with non-destructive FTIR spectroscopy. The infrared radiation penetrates the seed and interacts with fatty acid bonds, providing compositional information without removing or destroying the seed sample, thus preserving it for further use in breeding programs.
Solution Approach 2:
The FTIR spectrum creates an informational copy of the seed's fatty acid composition through vibrational transitions of chemical bonds. This copying process extracts analytical data without physically altering or destroying the seed, maintaining seed integrity while obtaining precise fatty acid profile information.
3Measurement precision
If laborious sampling and extraction procedures are followed, then measurement precision is improved, but ease of operation is worsened
Solution Approach 1:
The patent replaces complex manual procedures involving sampling, solvent extraction, hydrolysis, and chromatographic separation with a single FTIR spectroscopic measurement. This substitution automates and simplifies the analytical process, requiring minimal sample preparation and eliminating multiple manual操作步骤, thereby greatly improving ease of operation.
Solution Approach 2:
The patent merges multiple separate analytical steps (extraction, hydrolysis, separation, detection) into a single FTIR spectroscopic measurement. This consolidation of functions into one operation eliminates the need for separate procedural steps, reducing operational complexity while maintaining analytical precision through comprehensive spectral analysis.
