Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional breeding techniques are used to develop soybean varieties with desirable traits, then the breeding process is time-consuming and unpredictable, but the resulting varieties exhibit genetic variability and environmental dependence
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional phenotypic selection to molecular marker-assisted selection, changing the fundamental parameter of trait detection from physical characteristics to genetic markers. This enables earlier and more accurate identification of desired traits, reducing breeding cycle time while improving predictability through direct genetic analysis rather than phenotypic observation.
Solution Approach 2:
The patent replaces the mechanical/phenotypic breeding system with a molecular genetics system. Instead of relying on manual selection based on physical traits and environmental performance, the invention uses molecular markers and genetic transformation techniques to directly manipulate and select for desired traits, thereby reducing the time and uncertainty inherent in conventional breeding methods.
2Stability of the object's composition
If conventional breeding techniques are used, then the process is simple and accessible, but it produces genetic variability and environmental dependence in the resulting varieties
Solution Approach 1:
The patent replaces conventional phenotypic selection with molecular marker-assisted selection and genetic transformation. This substitution uses molecular biology tools to directly manipulate and stabilize the genetic composition of soybean varieties, eliminating the genetic variability and environmental dependence that characterize conventionally bred varieties, while the complexity of molecular techniques is managed through standardized protocols.
Solution Approach 2:
The invention changes the parameter of trait identification from phenotypic characteristics to molecular genetic markers. This parameter change enables precise control over genetic composition by selecting and transforming specific genes and DNA sequences, thereby achieving genetic stability and consistency in the resulting varieties that cannot be obtained through conventional breeding methods.
3Productivity
If conventional breeding techniques are used to achieve high yield and desirable traits, then the process is straightforward, but the varieties lack stable performance and desirable traits are not consistently achieved
Solution Approach 1:
The patent applies molecular marker-assisted selection and genetic transformation to replace conventional breeding methods. This substitution enables the consistent achievement of high yield and desirable traits by directly manipulating specific genes and genetic pathways, thereby producing varieties with both high productivity and stable performance that reliably express desired characteristics across different environments.
Solution Approach 2:
The invention changes the approach from phenotypic selection to molecular genetic manipulation. By working at the DNA level rather than the phenotypic level, the patent achieves precise control over traits such as yield, disease resistance, and nutritional quality, ensuring consistent expression of these traits in the resulting varieties while maintaining stability across generations and environmental conditions.
