Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop soybean varieties with improved traits, then genetic diversity and trait combinations can be explored, but the process requires extensive research efforts and time due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by creating isogenic lines through repeated backcrossing (BC3F3 generation) before introducing the target trait. This pre-establishment of genetic uniformity accelerates subsequent trait evaluation and variety development, reducing the overall breeding cycle time while maintaining genetic diversity exploration capabilities
2Stability of the object's composition
If multiple backcrossing generations are performed to achieve stable trait inheritance, then trait stability and uniformity are improved, but the breeding process complexity and research effort increase
Solution Approach 1:
The patent uses isogenic lines as genetic copies that are nearly identical except for the specific trait being introduced. This copying approach simplifies the breeding process by maintaining genetic uniformity across generations, reducing the complexity of tracking multiple genetic variations while ensuring stable trait inheritance in the BC3F3 and subsequent generations
3Reliability
If extensive field testing and evaluation are conducted to ensure variety stability, then variety reliability and performance consistency are improved, but the time and resources required for research efforts increase
Solution Approach 1:
The patent implements feedback through multi-environment field testing of the BC3F3 generation and subsequent varieties. The isogenic nature of the lines provides consistent baseline performance, allowing researchers to quickly identify and eliminate variable performers. This feedback mechanism accelerates the evaluation process by reducing noise from genetic variation, enabling faster confirmation of variety reliability across different locations and seasons
