Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional plant breeding methods are used to develop squash hybrids, then the breeding process is simpler and less costly, but the resulting hybrids do not achieve sufficient improvement in yield, fruit quality, and disease resistance
Solution Approach 1:
The patent applies parameter changes by modifying genetic parameters through CRISPR/Cas technology to achieve superior hybrid traits. The breeding process transitions from conventional methods to genome editing, changing the fundamental parameter of genetic modification to resolve the contradiction between improved productivity and increased complexity.
Solution Approach 2:
The patent replaces mechanical breeding methods (crossing and selection) with molecular biology techniques (CRISPR/Cas genome editing). This substitution enables precise genetic modifications that conventional mechanical breeding cannot achieve, thereby improving yield and disease resistance despite the increased technical complexity.
2Reliability
If advanced genetic modification techniques like CRISPR/Cas are used, then disease resistance and nutritional quality are improved, but the breeding process becomes more complex and technologically demanding
Solution Approach 1:
The patent changes genetic parameters by introducing specific gene edits through CRISPR/Cas technology to enhance disease resistance and nutritional quality. This parameter change approach allows precise modification of traits related to reliability while managing the complexity through targeted genetic interventions.
Solution Approach 2:
The patent applies local quality by making specific, targeted genetic modifications at particular loci using CRISPR/Cas technology. Rather than genome-wide changes, the approach focuses on specific genes or regions responsible for disease resistance and nutritional quality, thereby improving reliability while controlling the overall complexity of the breeding process.
3Stability of the object's composition
If multiple breeding cycles including backcrossing are performed, then desirable traits are stabilized in the hybrid, but the breeding time and resource requirements increase
Solution Approach 1:
The patent replaces multi-generational mechanical breeding cycles with direct genome editing using CRISPR/Cas technology. This substitution achieves trait stabilization in fewer generations by directly introducing desired genetic modifications, thereby reducing the time loss associated with conventional backcrossing and multiple breeding cycles.
Solution Approach 2:
The patent applies preliminary action by performing genome editing to pre-establish desired traits before hybridization. By using CRISPR/Cas to pre-modify parental lines with target traits, the breeding process achieves stable hybrid composition more quickly, reducing the time required for multiple stabilization cycles.
