Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current genetic modification techniques are used, then yield increase is limited, but the complexity of developing effective modifications increases
Solution Approach 1:
The invention segments the complex genetic modification process by identifying and targeting specific gene families (BG1, BG2, BG3) that control yield-related traits. Instead of attempting comprehensive genome modification, the patent focuses on modifying specific genes within these families, breaking down the complex problem into manageable genetic targets that can be addressed individually through targeted mutagenesis or gene editing approaches.
Solution Approach 2:
The invention changes genetic parameters by introducing specific mutations or modifications to BG1/BG2/BG3 gene sequences that alter their expression patterns or protein function. This involves changing nucleotide sequences, amino acid compositions, or regulatory elements of these genes to achieve desired yield increases while avoiding the need for complex multi-gene modification systems.
2Reliability
If current methods are used to improve drought tolerance, then effectiveness is limited, but the time and resources required for development increase
Solution Approach 1:
The invention performs preliminary action by pre-identifying BG1/BG2/BG3 gene family members that are associated with drought tolerance through sequence analysis and homology searches. By preparing targeted modification strategies for these specific genes before field testing, the patent reduces the time required for developmental iterations and accelerates the breeding process for drought-tolerant varieties.
Solution Approach 2:
The invention uses copying by identifying and utilizing homologous sequences from related plant species to design modification strategies for BG1/BG2/BG3 genes. By copying successful genetic modifications or regulatory elements from drought-tolerant species and adapting them to target crops, the patent reduces development time while maintaining effectiveness.
3Productivity
If yield is increased through genetic modification, then kernel row numbers increase, but the precision of controlling specific traits decreases
Solution Approach 1:
The invention applies local quality by targeting specific BG1/BG2/BG3 gene family members that are responsible for particular yield components such as kernel row number, kernel number per row, or test weight. By modifying individual genes within these families rather than applying blanket modifications, the patent can precisely control specific traits while achieving overall yield increases, maintaining trait control precision.
Solution Approach 2:
The invention segments yield into controllable components by associating specific BG1/BG2/BG3 genes with specific yield traits. This allows the patent to modify genes that control kernel row number independently from those controlling other traits, enabling precise manipulation of individual yield components to achieve targeted improvements without compromising overall trait control.
