Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection methods are used for Zika virus nucleic acid, then the detection process is simple, but the sensitivity and specificity are inadequate
Solution Approach 1:
The detection system is segmented into distinct functional components: amplification oligomers for nucleic acid amplification, detection probe oligomers for specific binding, and separate detection mechanisms. This segmentation allows each component to be optimized for its specific function, thereby improving overall detection sensitivity and specificity without creating an impenetrably complex system.
Solution Approach 2:
The patent introduces intermediary molecules including amplification oligomers that act as mediators between the target Zika virus nucleic acid and the detection system. These intermediaries amplify the target sequence and enable sensitive detection, bridging the gap between simple detection and high sensitivity requirements.
2Productivity
If amplification oligomers are designed to hybridize to opposite ends of the target sequence, then the amplification efficiency is improved, but the oligomer design complexity increases
Solution Approach 1:
The amplification process is segmented into multiple steps with specific oligomers designed for opposite ends of the target sequence. This segmentation enables simultaneous amplification from both directions, improving productivity while maintaining manageable design complexity through standardized primer design protocols.
Solution Approach 2:
The patent optimizes parameters such as oligomer length, melting temperature, and sequence composition to achieve efficient hybridization at opposite ends of the target sequence. By systematically adjusting these parameters, high amplification efficiency is achieved without excessive design complexity.
3Measurement precision
If the target hybridizing sequence is made longer, then the detection specificity is improved, but the amplification efficiency may be reduced
Solution Approach 1:
The patent optimizes the length parameter of target hybridizing sequences to a specific range that balances specificity and amplification efficiency. By carefully controlling this parameter along with other conditions such as annealing temperature and oligomer concentrations, the system achieves both high specificity and efficient amplification.
Solution Approach 2:
The system dynamically adjusts hybridization conditions including temperature, time, and salt concentration to optimize the balance between specificity and efficiency. This dynamic approach allows longer sequences to be used for specificity without permanently sacrificing amplification efficiency, as conditions can be optimized for each specific application.
