Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new soybean varieties, then genetic diversity and adaptability can be improved, but the process is time-consuming and unpredictable
Solution Approach 1:
The patent applies preliminary action by creating and maintaining a diverse germplasm collection before the actual breeding process. The germplasm collection is pre-assembled with diverse genetic material from multiple sources, allowing breeders to immediately utilize this pre-prepared genetic diversity when initiating new variety development, thereby reducing the overall time required for breeding.
Solution Approach 2:
The patent uses an intermediary approach by introducing a controlled pollination system that acts as a mediator between the diverse germplasm collection and the target variety development. This controlled pollination system enables precise combination of genetic material from the diverse collection with selected parents, facilitating predictable and efficient variety development while maintaining genetic diversity.
2Adaptability or versatility
If conventional breeding methods are used to develop new soybean varieties, then genetic diversity can be maintained, but the final variety is unpredictable
Solution Approach 1:
The patent implements feedback mechanisms through systematic evaluation and selection processes. Performance data from trial crops is fed back into the breeding program to guide subsequent selection decisions, allowing breeders to adjust their approach based on actual performance results. This feedback loop increases the reliability and predictability of variety development while maintaining genetic diversity through informed selection.
Solution Approach 2:
The patent replaces purely mechanical/conventional breeding approaches with a more systematic, data-driven approach that incorporates controlled pollination and selective breeding. This substitution of breeding methodology increases predictability by using controlled crosses and selection criteria rather than relying solely on natural pollination and random selection, while still maintaining genetic diversity through strategic germplasm utilization.
3Productivity
If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the breeding complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct, manageable modules. The germplasm collection is segmented into different genetic sources, and the breeding process is segmented into sequential steps: selection of parents, controlled pollination, evaluation, and selection. This segmentation allows complex multi-trait varieties to be developed through systematic, step-by-step combination of desirable traits from different genetic sources, reducing overall program complexity.
Solution Approach 2:
The patent uses a universal germplasm collection that serves multiple functions simultaneously. The diverse germplasm collection acts as both a source of genetic diversity, a repository for specific trait combinations, and a resource for creating controlled crosses. This multi-functionality of the germplasm collection enables the efficient combination of multiple desirable traits in single varieties while reducing breeding program complexity through a single, versatile resource base.
