Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding is used to combine desirable traits, then the breeding process is simple and well-established, but the ability to achieve multiple desirable traits simultaneously (such as disease resistance, drought tolerance, uniformity, and yield) is limited
Solution Approach 1:
The patent applies parameter changes by utilizing molecular markers and genomic information to identify and select plants with specific genetic combinations. By changing the selection parameters from traditional phenotypic selection to genotypic selection based on molecular markers, the breeding process achieves better combination of multiple traits while maintaining manageability through automated or assisted selection processes.
2Productivity
If mechanical harvesting is implemented, then harvesting efficiency is improved, but uniformity of plant characteristics (germination, stand establishment, growth rate, maturity, plant height, ear height) becomes critical and difficult to maintain
Solution Approach 1:
The patent replaces traditional mechanical selection methods with molecular marker-assisted selection. By using DNA-based markers to identify and select plants with desired characteristics, the breeding process achieves superior uniformity of plant characteristics without relying solely on mechanical selection methods, thereby supporting efficient mechanical harvesting.
Solution Approach 2:
The patent incorporates feedback mechanisms through molecular marker analysis and genomic information to continuously monitor and adjust the selection process. This feedback allows for precise control over plant characteristics to ensure uniformity required for mechanical harvesting, while maintaining high productivity.
3Productivity
If conventional breeding methods are used, then the breeding timeline is shorter, but the achievement of superior yield and agronomic quality is limited
Solution Approach 1:
The patent applies preliminary action by using molecular markers and genomic information to identify and select plants with desirable traits early in the breeding process. This allows for accelerated selection and combination of multiple traits (disease resistance, drought tolerance, uniformity, yield) in fewer generations, thereby reducing the breeding timeline while achieving superior crop yield and agronomic quality.
