Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive greenhouse and field trials with numerous plant transformation events are conducted to select optimal cotton events, then reliable selection of commercially suitable events is achieved, but time consumption and resource requirements increase significantly
Solution Approach 1:
The patent applies preliminary action by developing and validating a rapid PCR-based detection method before conducting extensive field trials. The method uses primers specific to the MON 88701 event to quickly identify and verify transgenic events, allowing researchers to pre-screen and validate events before committing to time-consuming greenhouse and field trials, thus reducing overall selection time while maintaining reliability
Solution Approach 2:
The patent replaces the traditional mechanical approach of physically testing numerous plant events through extensive greenhouse and field trials with a molecular detection system. The PCR-based method substitutes the time-consuming phenotypic screening process with rapid genetic identification, enabling reliable event selection without requiring extensive physical trial data collection
2Reliability
If a large number of individual plant transformation events are produced and analyzed to find optimal characteristics, then suitable commercial events are identified, but the complexity and cost of data collection and analysis increase
Solution Approach 1:
The patent extracts the essential identification function from the complex process of analyzing numerous transformation events. By developing a specific PCR assay with event-specific primers, the method isolates the critical task of event identification from the broader complexity of phenotypic screening and data analysis, enabling accurate event selection with simplified methodology
Solution Approach 2:
The patent changes the detection parameter from complex phenotypic characteristics requiring multi-year field trial data to simple molecular genetic markers. The PCR method detects specific DNA sequences unique to the MON 88701 event, transforming the selection criterion from complex agronomic performance data to straightforward genetic presence/absence detection
3Reliability
If traditional methods are used to produce herbicide-tolerant cotton, then desirable traits are achieved, but the process is resource-intensive and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-validating the MON 88701 event through molecular characterization and preliminary field testing before widespread deployment. The specific PCR method was developed and validated in advance, enabling rapid identification and verification of the event without requiring repeated resource-intensive screening processes
Solution Approach 2:
The patent uses molecular copying through PCR amplification to create multiple copies of the target DNA sequence for analysis. This allows repeated detection and verification of the herbicide tolerance trait without requiring additional plant material or re-testing, significantly improving production efficiency while maintaining reliability
