Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nucleic acid amplification analysis is performed using calibrator and positive control measurements, then the reliability of amplification determination is improved, but the preparation complexity and operational complexity increase significantly
Solution Approach 1:
The invention extracts and utilizes the saturation state information from the amplification reaction curve itself, rather than requiring separate calibrator and control measurements. By taking out the key diagnostic feature (saturation state) directly from the measurement process, the system achieves reliable amplification determination without the complex preparation of additional controls
Solution Approach 2:
The measurement sample's amplification reaction provides its own reference information through the saturation state. The system uses the inherent characteristics of the amplification curve (the saturation point) as a self-reference, eliminating the need for external calibrators and controls, thereby simplifying preparation while maintaining determination reliability
2Reliability
If calibrator and positive control measurements are performed every time reagents are exchanged, then amplification reaction success determination is ensured, but the time consumption and operational steps increase
Solution Approach 1:
The invention extracts the necessary reference information directly from the amplification reaction curve's saturation state, eliminating the need for separate calibrator and control measurements that consume time. This extraction approach provides determination reliability without the time penalty of multiple measurements
Solution Approach 2:
The system performs preliminary analysis of the amplification curve to identify the saturation state during the normal measurement process itself, rather than requiring additional preliminary measurements of calibrators and controls. This integrates the reference function into the main measurement flow, reducing overall preparation time
3Measurement precision
If multiple measurement steps (calibrator, positive control, sample) are performed, then amplification success determination accuracy is improved, but the number of operational steps and ease of operation deteriorates
Solution Approach 1:
The invention merges the functions of calibrator measurement, control measurement, and sample measurement into a single integrated process. By combining these separate measurement steps and using the saturation state as a unified reference point, the system maintains determination accuracy while significantly improving operational simplicity
Solution Approach 2:
The saturation state parameter serves multiple functions simultaneously: it acts as a reference for determining amplification success, provides information about reaction completeness, and eliminates the need for separate control measurements. This multi-functionality maintains measurement precision while reducing operational complexity
