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 time due to the complexity of genetic combinations and environmental factors
Solution Approach 1:
The patent applies preliminary action by pre-introducing specific transgenic genes (MON89788, A5547-127, MON87708) into the soybean variety 01083659 during the breeding process. This allows the desired traits for herbicide resistance and disease tolerance to be established in advance through genetic transformation, rather than relying on traditional slow methods of selecting and combining these traits through multiple generations of crossing and screening. The backcrossing process also preliminarily establishes the genetic background before final variety development.
2Reliability
If transgenic genes are introduced to achieve herbicide resistance and disease tolerance, then specific trait performance is improved, but the genetic modification process and trait stability prediction become more complex
Solution Approach 1:
The patent applies segmentation by introducing each desired trait through separate, well-defined transgenic events (MON89788 for glyphosate resistance, A5547-127 for glufosinate resistance, MON87708 for dicamba tolerance). Each gene insertion is an independent, characterized event with known genetic mechanisms. The backcrossing process further segments the genome to recover the desired genetic background while retaining the specific transgenic loci, making the complex genetic modification process more manageable and predictable.
3Adaptability or versatility
If multiple transgenic events are combined in a single variety, then multiple traits are achieved simultaneously, but the genetic stability and trait expression consistency become more difficult to predict
Solution Approach 1:
The patent uses backcrossing as an intermediary process to stabilize the genetic composition of the multi-trait variety. By repeatedly crossing the transgenic parent with the desired recurrent parent and selecting progeny that retain the transgenic events while recovering the recurrent parent's genome, the backcrossing process acts as a mediator that reduces genetic background complexity and stabilizes trait expression. This intermediary step ensures that the multiple transgenic events are maintained in a stable genetic context.
