Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding methods are used to develop new soybean varieties, then genetic diversity and adaptability are maintained, but the process is unpredictable and time-consuming
Solution Approach 1:
The patent applies preliminary action by using genomic selection to predict breeding outcomes before actual crossing occurs. Genomic estimated breeding values (GEBV) are calculated for parental lines based on genomic data, allowing breeders to select and cross lines with predicted superior performance. This predictive approach enables more reliable breeding decisions to be made earlier in the process, reducing the time needed for traditional phenotypic evaluation and selection cycles.
Solution Approach 2:
The patent replaces the mechanical system of traditional phenotypic selection and field testing with a genomic-based predictive system. Instead of relying on physical observation and manual selection over multiple generations, the invention uses genomic data analysis, statistical models, and computational algorithms to predict and select superior breeding combinations, thereby increasing reliability and reducing breeding program duration.
2Reliability
If extensive breeding programs are implemented to achieve superior traits, then variety performance improves, but research effort and cost increase
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct modular components: (1) genomic data collection and processing, (2) genomic selection and prediction, (3) targeted crossing design, and (4) validation testing. This segmentation allows each component to be optimized independently and reduces overall program complexity by focusing resources on high-impact activities rather than conducting comprehensive evaluations of all possible breeding combinations.
Solution Approach 2:
The patent uses copying in the form of genomic data replication and verification. Genomic information is collected from multiple individuals and replicated across different populations to create robust predictive models. This copying approach allows the breeding program to rely on replicated genomic data rather than requiring extensive unique field testing for each potential parent line, thereby reducing program complexity while maintaining performance reliability.
3Adaptability or versatility
If multiple traits are combined in a single variety, then agronomic quality improves, but genetic combination unpredictability increases
Solution Approach 1:
The patent applies universality through the use of a unified genomic selection framework that simultaneously predicts multiple traits. The genomic prediction models are designed to evaluate diverse traits including yield, disease resistance, drought tolerance, and quality characteristics using the same genomic data and analytical platform. This multi-functional approach allows breeders to combine multiple traits in a single variety while maintaining predictability, as the genomic system can assess the additive and interactive effects of multiple genes and loci across different traits.
