Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional soybean breeding methods are used, then desirable traits can be combined in a single variety, but the process is time-consuming and requires many years (6-12 years) from first cross to finished seed delivery
Solution Approach 1:
The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting germplasm with desired traits before crossing, and planning multiple generations of selection and evaluation in advance. This organized approach reduces the 6-12 year development time by ensuring efficient use of resources and minimal changes in direction throughout the breeding process.
Solution Approach 2:
The patent implements feedback through continuous evaluation of breeding progress, monitoring trait expression in successive generations, and adjusting selection criteria based on performance data. This feedback mechanism ensures the breeding program stays on track and achieves desired traits efficiently, reducing overall development time.
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then agronomic performance improves, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: germplasm selection, crossing, F1 generation evaluation, F2 generation selection, and advanced generation testing. Each phase focuses on specific traits or objectives, making the overall complex process of combining multiple desirable traits more manageable and systematic.
Solution Approach 2:
The patent applies local quality by concentrating on specific trait combinations in specific generations. For example, early generations focus on basic trait inheritance while later generations focus on stabilizing specific agronomic characteristics. This localized approach to trait combination reduces overall program complexity by addressing one aspect at a time.
3Stability of the object's composition
If self-pollination is used to ensure homozygosity and phenotypic stability, then variety uniformity improves, but the breeding process becomes more restrictive
Solution Approach 1:
The patent applies dynamics by using self-pollination selectively in later generations (F3 and beyond) when homozygosity is needed for stability, while allowing controlled cross-pollination in earlier generations (F1, F2) to maintain breeding flexibility and combine diverse traits. This dynamic approach to pollination strategy balances phenotypic stability with breeding adaptability.
