Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional 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 is difficult to predict due to complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by creating isogenic lines through repeated backcrossing before the final cross. This preliminary generation of genetically uniform lines (advanced to F6-F8 generations) establishes a controlled genetic background that reduces unpredictable variation in subsequent generations, thereby reducing the time and research efforts needed for variety development while maintaining trait combination diversity
2Reliability
If multiple backcrossing generations are performed to achieve isogenic lines, then genetic uniformity and predictability are improved, but the breeding process complexity and time requirement increase
Solution Approach 1:
The patent applies copying by repeatedly backcrossing the donor parent to the recurrent parent to create multiple copies of the recurrent parent's genome in the progeny. This generates isogenic lines that are genetic copies of the recurrent parent except for the introgressed trait segments, achieving genetic uniformity while standardizing the breeding process
Solution Approach 2:
The patent applies segmentation by dividing the breeding process into distinct generational stages (F1, F2, F3, F4, F5, F6, F7, F8) with specific selection criteria at each stage. This segments the complex breeding process into manageable steps, reducing overall process complexity through systematic progression
3Measurement precision
If extensive breeding research is conducted to predict trait performance, then accuracy of trait prediction is improved, but cost and time associated with traditional breeding methods increase
Solution Approach 1:
The patent applies preliminary action by conducting multiple generations of backcrossing and selection (F2-F8 generations) before final variety development. This preliminary establishment of isogenic lines with known genetic backgrounds enables more accurate prediction of trait performance in subsequent generations, reducing the need for extensive ongoing research while improving prediction accuracy
Solution Approach 2:
The patent applies feedback by evaluating and selecting plants at each generation based on desired traits (herbicide resistance, disease resistance, yield components). This iterative feedback process refines the genetic lines progressively, improving trait prediction accuracy for the final variety while reducing overall development time through targeted selection
