Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to develop disease-resistant varieties, then disease resistance is improved, but the breeding process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with known disease resistance traits and using marker-assisted selection to track desired resistance genes through generations. This allows breeders to anticipate and plan for resistance inheritance patterns, significantly reducing the time required to develop resistant varieties compared to traditional trial-and-error breeding approaches.
2Reliability
If multiple disease resistance traits are combined in a single variety, then comprehensive resistance is improved, but the breeding complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct modules: selecting for resistance to specific diseases (e.g., cyst nematode, sudden death syndrome, brown stem rot) independently, then systematically combining these resistance traits. This modular approach allows breeders to manage complexity by handling one resistance trait at a time while using marker-assisted selection to track multiple traits simultaneously.
Solution Approach 2:
The patent applies universality by developing a standardized breeding protocol using marker-assisted selection that can be applied across multiple disease resistance traits. The same molecular markers and selection procedures are used universally for different diseases, reducing the need for separate breeding programs for each disease and simplifying the overall process of combining multiple resistance traits.
3Stability of the object's composition
If extensive field testing is conducted to ensure variety stability, then trait uniformity is improved, but the time required for variety development increases
Solution Approach 1:
The patent applies mechanics substitution by replacing extensive phenotypic field testing with molecular marker-based genotypic analysis. Instead of growing and evaluating thousands of plants across multiple locations to assess trait uniformity, breeders use DNA markers to directly detect the presence and consistency of desired resistance genes, dramatically reducing testing time while maintaining or improving accuracy in assessing variety stability.
