Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties, then breeding programs can be established, but the process is time-consuming and unpredictable, resulting in significant research costs and variability in soybean varieties
Solution Approach 1:
The patent applies preliminary action by using molecular marker-assisted selection to identify and select plants with desirable traits before completing the full breeding cycle. This allows breeders to make informed decisions early in the process, reducing the time needed for conventional phenotypic selection and increasing breeding predictability through genetic markers that indicate desired characteristics.
Solution Approach 2:
The patent replaces mechanical/phenotypic selection methods with molecular genetic tools. Instead of relying on physical observation and manual selection of traits, the invention uses DNA-based molecular markers to identify and select plants with desired characteristics, thereby reducing breeding time and increasing reliability while maintaining the ability to develop stable, high-yielding varieties.
2Manufacturing precision
If conventional breeding techniques are used, then breeding programs can progress, but the resulting soybean varieties show significant variability and require extensive research costs
Solution Approach 1:
The patent substitutes conventional phenotypic evaluation methods with molecular marker analysis. This allows for precise identification of plants with desired genetic traits, ensuring variety consistency while reducing the need for extensive resource-intensive field testing and multiple breeding cycles required by conventional methods.
Solution Approach 2:
The patent implements feedback through molecular marker analysis that provides immediate genetic information about plant traits. This feedback mechanism allows breeders to quickly identify and select plants with desired characteristics, reducing the number of breeding cycles needed and thereby decreasing overall research resource requirements while improving variety consistency.
3Object-affected harmful factors
If transgenic genes are introduced for herbicide resistance and disease resistance, then plant protection is improved, but the complexity of the breeding program increases
Solution Approach 1:
The patent applies preliminary action by introducing transgenic genes with desired resistance traits early in the breeding program. Molecular markers are used to track the inheritance of these transgenic genes, allowing breeders to select for resistance characteristics before the plants are fully grown, thereby simplifying the overall breeding process despite the added complexity of transgenic technology.
