Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current detection methods are used for VZV, then the detection process is simple, but the sensitivity and specificity are insufficient
Solution Approach 1:
The detection system is segmented into distinct functional components: amplification oligonucleotides for DNA amplification, detection probes for specific target recognition, and detection reagents for signal generation. This segmentation allows each component to be optimized independently for sensitivity and specificity while maintaining overall system manageability
Solution Approach 2:
The patent introduces amplification oligonucleotides and detection probes as intermediary elements between the VZV target and the detection system. These intermediaries enable indirect detection through amplification and specific hybridization, significantly improving detection sensitivity and specificity compared to direct detection methods
2Productivity
If rapid detection of VZV is implemented, then the detection time is reduced, but the accuracy may be compromised
Solution Approach 1:
The detection system performs preliminary amplification of the VZV target using specific amplification oligonucleotides before detection. This preliminary action increases the amount of target material available for detection, enabling rapid and accurate detection even from small initial samples
Solution Approach 2:
The patent employs parameter changes in the form of temperature cycling and chemical conditions optimization to enable rapid amplification and detection. By carefully controlling reaction parameters, the system achieves both speed and accuracy in VZV detection
3Reliability
If specific amplification oligonucleotides and probes are developed, then the detection specificity is improved, but the development complexity increases
Solution Approach 1:
The amplification oligonucleotides and detection probes are designed with local quality optimization, where specific regions of the oligonucleotides are tailored for binding to particular VZV genomic regions. This localized optimization ensures high specificity while using standard oligonucleotide synthesis methods
Solution Approach 2:
The detection system uses universal components such as standard PCR buffers, common fluorophores, and widely-used polymerases. These universal reagents simplify the manufacturing and implementation process while the specificity is achieved through the customized oligonucleotide sequences
