Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gel electrophoresis is used to differentiate soybeans with high β-conglycinin content, then measurement precision is improved, but device complexity and labor intensity increase significantly
Solution Approach 1:
The patent replaces the mechanical/chemical gel electrophoresis system with an optical sensing system. The method involves heating soybean samples to release volatile compounds, then using optical sensors to detect these volatiles and generate electronic signals for differentiation. This substitution eliminates the need for complex gel electrophoresis equipment while maintaining the ability to accurately differentiate soybean varieties based on β-conglycinin content.
Solution Approach 2:
The patent changes the detection parameter from protein separation patterns (requiring gel electrophoresis) to volatile compound emission characteristics. By heating the samples and detecting the resulting volatiles through optical sensing, the method transforms the differentiation approach into a simpler, faster process that doesn't require complex equipment while maintaining measurement precision.
2Measurement precision
If gel electrophoresis is used to differentiate soybean varieties, then measurement precision is improved, but time consumption increases
Solution Approach 1:
The patent replaces the time-consuming gel electrophoresis process with a rapid optical sensing method. The simplified system heats samples and detects volatile compounds through optical sensors, eliminating the lengthy gel electrophoresis procedure while maintaining accurate variety differentiation capability.
Solution Approach 2:
The patent extracts only the essential information needed for differentiation through volatile compound detection, rather than performing the complete gel electrophoresis analysis. This extraction approach allows for rapid identification of soybean varieties by focusing on the most distinguishing chemical signatures released during heating.
3Measurement precision
If conventional differentiation methods are used at grain delivery points, then measurement precision is improved, but ease of operation deteriorates due to high labor intensity
Solution Approach 1:
The patent replaces labor-intensive gel electrophoresis with an automated optical sensing system that can be easily operated at grain delivery points. The system automatically heats samples, detects volatiles through optical sensors, and processes signals to provide differentiation results, eliminating the need for skilled laboratory personnel and complex manual procedures.
Solution Approach 2:
The patent enables the soybean samples to essentially differentiate themselves through their unique volatile emission patterns when heated. The optical sensing system passively detects these natural chemical signatures without requiring complex sample preparation or skilled operation, making the process self-service friendly for point-of-delivery use.
