Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soybean breeding methods are used to combine desirable traits, then the variety can achieve high yield and disease resistance, but the development process takes 6-12 years and requires multiple directional changes
Solution Approach 1:
The patent applies preliminary action by using self-pollination to establish homozygosity and phenotypic stability before initiating the breeding program. This preparatory step ensures that the parental lines are genetically uniform and stable, reducing the need for later directional changes and accelerating the overall breeding process while maintaining trait reliability
2Manufacturing precision
If traditional breeding methods are used to develop new varieties, then trait combination is achieved, but the process requires precise planning and efficient resource use with minimal directional changes
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: selection of germplasm with specific traits, self-pollination to establish homozygosity, controlled crossing to combine traits, and evaluation. This segmented approach simplifies the overall program complexity while maintaining precision in trait combination by focusing on one objective at each stage
3Stability of the object's composition
If self-pollination is used to ensure homozygosity, then phenotypic stability is achieved, but the breeding process becomes more resource-intensive
Solution Approach 1:
The patent applies self-service by utilizing the natural self-pollination capability of soybean plants to achieve homozygosity. This eliminates the need for complex人工 intervention systems while maintaining phenotypic stability. The plants serve themselves by self-pollinating, reducing the resource intensity compared to methods requiring extensive manual pollination or sophisticated controlled environments
