Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination between different plant varieties is used to create hybrid plants, then genetic diversity and adaptability are improved, but uniformity and predictability of performance deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct stages: creating F1 hybrid plants with desired traits, then developing inbred lines through repeated self-pollination. This segmentation allows the benefits of cross-pollination (genetic diversity) to be captured in the F1 generation while achieving uniformity in the subsequent inbred lines through controlled self-pollination over multiple generations.
Solution Approach 2:
The patent employs preliminary action by first creating uniform F1 hybrid plants through controlled cross-pollination before proceeding to develop inbred lines. This preliminary F1 generation establishes the desired genetic combination, which is then maintained and stabilized through subsequent self-pollination generations, ensuring both uniformity and predictability in the final inbred lines.
2Stability of the object's composition
If self-pollination is used to create homozygous inbred plants, then uniformity and predictability are improved, but genetic diversity and adaptability deteriorate
Solution Approach 1:
The patent segments the breeding process to first create F1 hybrids with genetic diversity through cross-pollination, then develops inbred lines through self-pollination. This segmentation allows the inbred lines to achieve uniformity while the F1 generation maintains the genetic diversity needed for adaptability.
Solution Approach 2:
The F1 hybrid generation acts as an intermediary between the diverse parental varieties and the uniform inbred lines. The F1 plants carry the genetic diversity from different parents while serving as a uniform starting point for developing inbred lines through self-pollination, thus mediating between the need for diversity and uniformity.
3Adaptability or versatility
If broad-based breeding pools are used to combine genetic backgrounds, then adaptability and trait combination are improved, but uniformity and breeding complexity deteriorate
Solution Approach 1:
The patent segments the breeding process into manageable steps: selecting parental varieties with desired traits, creating F1 hybrids, then developing inbred lines through systematic self-pollination. This segmentation reduces the complexity of working with broad-based breeding pools by breaking down the complex process into discrete, controllable stages.
Solution Approach 2:
The patent utilizes parameter changes by transitioning from cross-pollination (increasing genetic diversity) to self-pollination (decreasing genetic diversity while increasing uniformity). This parameter change in the pollination method allows the breeding program to manage complexity by systematically controlling the genetic composition at each stage.
