Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding is used to combine desirable traits, then various traits such as disease resistance and drought tolerance can be integrated, but the process is time-consuming and lacks precision in achieving uniformity
Solution Approach 1:
The patent applies parameter changes by utilizing molecular markers and genomic information to identify and select plants with desired traits at the genetic level, rather than relying solely on phenotypic observation over multiple generations. This accelerates the breeding process while maintaining the ability to combine multiple desirable traits including disease resistance, drought tolerance, and uniformity.
2Stability of the object's composition
If conventional breeding methods are applied to achieve uniformity in plant characteristics, then genetic uniformity can be improved, but mechanical harvesting efficiency and agronomic quality are compromised
Solution Approach 1:
The patent applies local quality by selecting and maintaining specific genetic variants that provide both uniformity in key characteristics and superior local adaptations for mechanical harvesting. The breeding program identifies plants with specific combinations of traits that ensure uniformity while maintaining agronomic quality suitable for mechanical operations.
3Adaptability or versatility
If traditional breeding is used to develop new varieties, then genetic diversity can be maintained, but the development of varieties with multiple desirable traits is inefficient
Solution Approach 1:
The patent uses molecular markers and genomic tools as intermediaries to track and combine desirable traits during the breeding process. These tools allow breeders to identify plants with multiple desired traits more efficiently, reducing the complexity of managing multi-trait development by providing objective criteria for selection.
