Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding methods are used, then breeding simplicity is maintained, but yield stability and fruit quality improvement are insufficient
Solution Approach 1:
The patent combines traditional breeding methods with New Breeding Techniques (NBTs) like CRISPR/Cas endonucleases to create a hybrid approach. This merging allows the integration of conventional crossing and selection procedures with precise genetic editing, achieving both yield improvement and breeding simplicity through complementary strengths of each method.
Solution Approach 2:
The patent utilizes CRISPR/Cas endonucleases to make precise parameter changes in the plant genome by targeting specific genes or sequences. This enables controlled modification of traits such as yield, fruit quality, and disease resistance without the complexity of traditional multi-generation breeding, directly addressing the contradiction between productivity improvement and breeding complexity.
2Reliability
If New Breeding Techniques like CRISPR/Cas endonucleases are used, then disease resistance and fruit quality are improved, but breeding technology complexity increases
Solution Approach 1:
The patent extracts and utilizes specific functional elements from the CRISPR/Cas system to achieve disease resistance. By focusing on the endonuclease activity and guide RNA components, the technology isolates the essential function of gene editing while managing complexity through targeted application rather than comprehensive system implementation.
Solution Approach 2:
The patent employs an intermediary approach by using CRISPR/Cas endonucleases as precise tools to modify plant genomes. This intermediary technology enables direct manipulation of genetic sequences responsible for disease resistance and fruit quality, achieving reliable trait improvement with controlled technical complexity through standardized protocols.
3Productivity
If hybridization is performed to improve fruit traits, then fruit quality and yield are enhanced, but genetic stability across generations may be compromised
Solution Approach 1:
The patent applies preliminary action by performing genetic editing with CRISPR/Cas endonucleases before hybridization to establish stable genetic modifications in parent lines. This preliminary genetic enhancement ensures that when hybrids are produced, the desired traits for fruit quality and yield are already encoded with high genetic stability, preventing deterioration across generations.
Solution Approach 2:
The patent creates composite genetic materials by combining CRISPR-edited parent lines with traditional hybridization. This composite approach integrates the genetic stability of edited lines with the vigor of hybrids, achieving both improved fruit traits and maintained genetic stability across generations through the synergistic combination of different breeding strategies.
