Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional analytical techniques (titration methods) are used to evaluate tallow characteristics, then measurement precision can be achieved, but the process becomes laborious, costly, and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical/chemical analytical techniques (titration methods requiring manual operations, chemical reagents, and lengthy procedures) with near-infrared spectroscopy, an optical-based method that provides rapid, automated analysis of tallow characteristics including moisture, free fatty acids, and insoluble impurities
Solution Approach 2:
The patent changes the measurement parameter from chemical composition analysis (requiring titration and chemical reactions) to spectroscopic analysis in the near-infrared region, enabling simultaneous multi-component analysis through wavelength-specific absorption patterns
2Reliability
If traditional analytical techniques are used, then reliable quality verification can be obtained, but environmental harm increases due to chemical reagent usage
Solution Approach 1:
The patent substitutes chemical-based analytical methods that require hazardous reagents with a physical optical method (near-infrared spectroscopy) that uses no chemicals, thereby eliminating environmental contamination while maintaining reliable quality verification capability
Solution Approach 2:
The near-infrared spectroscopy method is self-sufficient, requiring no external chemical reagents or complex sample preparation, and directly provides reliable quality data through non-destructive optical measurement
3Measurement precision
If traditional bench analytical techniques are used, then detailed characterization can be achieved, but device complexity and operational difficulty increase
Solution Approach 1:
The near-infrared spectroscopy system performs multiple characterization functions simultaneously (moisture content, free fatty acid levels, insoluble impurities) through a single instrument and measurement process, eliminating the need for multiple separate analytical procedures and reducing operational complexity

AI summary
A characteristic of tallow may be evaluated using a spectrometer such as a near infrared (NIR) spectrometer. For example, optical reflectance data may be obtained from tallow, the reflectance data corresponding to a specified range of infra-red wavelengths. A value corresponding to the characteristic may be output based on the reflectance data generated by the spectrometer. The characteristic may include moisture, free fatty acid, or insoluble impurities as a percentage or concentration in a sample, for example.
