Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding techniques are used to combine multiple desirable traits, then the breeding process becomes increasingly complex and time-consuming, but the ability to effectively combine traits like disease resistance, drought tolerance, and herbicide resistance remains limited
Solution Approach 1:
The patent employs molecular markers as intermediary tools to facilitate trait combination. These markers serve as detectable indicators that guide the breeding process, allowing breeders to select plants with desired trait combinations more efficiently. The markers act as mediators between the complex genetic makeup and the selection process, simplifying the overall breeding complexity while enhancing the ability to combine multiple desirable traits.
Solution Approach 2:
The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of relying on visual inspection and manual selection of trait expressions, the invention uses DNA-level molecular markers to identify and select plants with desired traits. This substitution of mechanical selection with molecular analysis reduces breeding process complexity and improves trait combination efficiency.
2Stability of the object's composition
If multiple generations of breeding and selection are performed to stabilize traits, then trait stability improves, but the time required to develop new varieties increases significantly
Solution Approach 1:
The patent performs preliminary molecular marker analysis at early breeding stages to identify plants with desired trait combinations before advancing to later generations. By conducting DNA-based selection early in the breeding process, the invention eliminates the need for multiple generations of phenotypic testing and stabilization, thereby reducing development time while maintaining trait stability through marker-guided selection.
Solution Approach 2:
The invention replaces traditional multi-generational phenotypic selection and stabilization processes with molecular marker-based selection. This substitution allows for direct identification of stable trait combinations at the DNA level, eliminating the time-consuming iterative process of growing multiple generations to stabilize traits while ensuring genetic stability through marker verification.
3Reliability
If extensive field testing and evaluation are conducted to ensure variety performance, then reliability of the variety improves, but the cost and time of variety development increase
Solution Approach 1:
The patent conducts preliminary molecular marker-based screening and evaluation at early stages of variety development to identify plants with desired trait combinations and performance characteristics. By performing DNA-level analysis and preliminary phenotypic evaluation before extensive field testing, the invention reduces the number of plants requiring full-scale field trials, thereby maintaining variety performance reliability while reducing overall testing time and costs.
