Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties, then multiple desirable traits can be combined, but the breeding process becomes complex and time-consuming
Solution Approach 1:
The patent applies parameter changes by modifying specific genetic loci through targeted breeding approaches. Instead of attempting to combine all desirable traits simultaneously through complex multi-parent crosses, the invention focuses on changing specific genetic parameters at key loci while maintaining the existing genetic background, thereby simplifying the breeding process while still achieving trait combination.
Solution Approach 2:
The breeding approach is segmented into distinct steps: first establishing a base variety with certain desirable traits, then separately introducing additional traits through targeted crosses and backcrosses. This segmentation allows each trait introduction to be managed independently, reducing overall process complexity while achieving cumulative trait combinations.
2Stability of the object's composition
If multiple generations of breeding are performed to stabilize varieties, then trait stability improves, but the breeding time increases
Solution Approach 1:
The patent employs preliminary action by performing multiple backcrosses to the original variety before final stabilization steps. This preliminary backcrossing establishes the genetic background early in the breeding process, allowing subsequent trait stabilization to proceed more efficiently and reducing the total time required for variety development.
Solution Approach 2:
The breeding method uses copying by repeatedly backcrossing to the original variety, effectively copying its stable genetic background into the new variety. This ensures that the final variety maintains the stability and desirable characteristics of the parent while incorporating new traits, reducing the need for extensive additional stabilization generations.
3Productivity
If extensive crossing and selection is performed to achieve high yield, then yield potential increases, but the breeding program complexity increases
Solution Approach 1:
The patent applies local quality by focusing selection efforts on specific traits and loci that have the greatest impact on yield, rather than attempting to optimize all traits simultaneously. This targeted approach allows yield potential to be maximized through improvement at key genetic locations while keeping the overall breeding program manageable in complexity.
