Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive research and time due to unpredictability of genetic combinations
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with desired traits (herbicide resistance, disease resistance, yield characteristics) before crossing. The breeding program systematically evaluates parental germplasm and plans crosses based on predetermined breeding objectives, reducing the time needed to develop varieties with specific trait combinations.
Solution Approach 2:
The patent employs feedback mechanisms through systematic evaluation of breeding progeny for desired traits. Performance data from field trials and genetic analysis feed back into the breeding program to guide selection decisions and improve subsequent crosses, accelerating the development of varieties with predictable trait expressions.
2Manufacturing precision
If backcrossing and genetic transformation techniques are used to introduce specific traits, then precision in trait introduction is improved, but device complexity and breeding process complexity increase
Solution Approach 1:
The patent applies segmentation by breaking down the complex breeding process into distinct stages: parental selection, controlled crossing, backcrossing generations, and trait evaluation. Each stage focuses on specific objectives, making the overall complex process more manageable and systematic while maintaining precision in trait introduction.
Solution Approach 2:
The patent uses molecular markers as intermediaries to track and select for desired traits during backcrossing. These markers serve as proxies for complex genetic traits, enabling precise selection without directly observing all genetic combinations, thus reducing process complexity while maintaining precision.
3Reliability
If extensive breeding research is conducted to ensure variety stability and uniformity, then variety reliability is improved, but productivity and breeding efficiency decrease
Solution Approach 1:
The patent replaces traditional mechanical phenotypic evaluation with molecular marker-based genotypic analysis. This substitution allows for more efficient and accurate assessment of genetic stability and uniformity, reducing the time and resources needed for extensive field trials while maintaining or improving variety reliability.
