Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional self-pollination breeding methods are used, then genetic stability is maintained, but breeding efficiency and productivity are limited
Solution Approach 1:
The patent extracts and removes the self-pollination capability from the corn plant by introducing cytoplasmic male sterility genes, preventing the plant from producing functional pollen. This forces cross-pollination while maintaining genetic control through the extraction of the harmful self-pollination function.
Solution Approach 2:
The patent uses cytoplasmic male sterility genes as an intermediary mechanism to control pollination. These genes act as a mediator that prevents self-pollination while allowing controlled cross-pollination, thereby improving breeding efficiency without compromising genetic stability through uncontrolled selfing.
2Adaptability or versatility
If cross-pollination is enforced to improve genetic diversity, then genetic stability may be compromised, but breeding efficiency improves
Solution Approach 1:
The patent extracts the self-pollination function through cytoplasmic male sterility, completely removing the ability of the plant to self-fertilize. This ensures cross-pollination and genetic diversity while maintaining stability through controlled breeding programs that use known genetic parents.
Solution Approach 2:
The patent changes the pollination parameter from self-compatible to self-incompatible by introducing cytoplasmic male sterility genes. This parameter change forces cross-pollination and increases genetic diversity while maintaining breedability through controlled crossing programs.
3Productivity
If male sterility traits are introduced to prevent self-pollination, then cross-pollination efficiency improves, but device complexity increases
Solution Approach 1:
The patent extracts pollen production capability through cytoplasmic male sterility genes, preventing self-pollination and ensuring cross-pollination. This genetic extraction simplifies the breeding process by eliminating the need for manual emasculation while the genetic complexity is managed through established molecular breeding techniques.
