Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current detection methods are used for SARS-CoV-2 nucleic acid, then the detection process is simple, but the sensitivity and specificity are inadequate
Solution Approach 1:
The detection method is divided into multiple sequential steps: sample collection, nucleic acid extraction, LAMP amplification, and detection. Each step is optimized independently to improve overall sensitivity and specificity while managing complexity through systematic breakdown of the detection process
Solution Approach 2:
The invention employs LAMP primers with specific nucleic acid sequences that target multiple regions of the SARS-CoV-2 genome. By changing the parameters of primer design and amplification conditions, the method achieves high sensitivity and specificity without requiring overly complex equipment
2Measurement precision
If LAMP primers with specific nucleic acid sequences are used, then detection sensitivity and specificity improve, but the kit complexity increases
Solution Approach 1:
The LAMP primer kit is designed to detect multiple SARS-CoV-2 variants simultaneously using a set of primers that target conserved regions of the viral genome. This multi-functional approach allows a single kit to handle various strains, reducing the need for multiple specialized primer sets and thereby managing complexity while maintaining high detection accuracy
Solution Approach 2:
The primer kit incorporates multiple sets of LAMP primers with different nucleic acid sequences that can detect various SARS-CoV-2 variants. By combining multiple primer sets into a single composite kit, the invention achieves broad detection capability while presenting a unified, manageable product structure
3Measurement precision
If detection methods are optimized for high sensitivity, then diagnostic accuracy improves, but the time required for detection increases
Solution Approach 1:
The LAMP primers are designed in advance to target multiple conserved regions of the SARS-CoV-2 genome simultaneously. This preliminary design ensures that amplification occurs rapidly across multiple targets, achieving high diagnostic accuracy within a shortened time frame compared to sequential testing methods
Solution Approach 2:
The LAMP amplification process operates continuously at a constant temperature without requiring the thermal cycling steps needed for PCR. This continuous isothermal amplification maintains high diagnostic accuracy while significantly reducing the total detection time by eliminating repeated heating and cooling cycles
