Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional algorithmic techniques or visual analysis are used to determine amplification, then the method is simple and easy to implement, but the accuracy of amplification determination is insufficient
Solution Approach 1:
The patent replaces traditional algorithmic techniques and visual analysis methods with deep learning-based artificial neural networks. The neural network model automatically learns complex patterns from amplification curve data, substituting manual or simple algorithmic evaluation with an intelligent system that achieves superior accuracy in determining amplification while automatically handling the complexity of pattern recognition.
2Productivity
If manual review of amplification curves is performed, then flexibility in analysis is maintained, but throughput of sample analysis is reduced
Solution Approach 1:
The patent implements an automated deep learning system that performs amplification determination independently without requiring manual review. The neural network model processes amplification curves automatically, extracting features and making determinations autonomously. This self-service approach enables high-throughput analysis while maintaining the flexibility and accuracy previously associated with manual expert review.
3Reliability
If existing automated methods are used, then throughput is improved, but accuracy of target presence prediction is insufficient for clinical applications
Solution Approach 1:
The patent employs a pre-trained deep learning model that has been trained on extensive amplification curve data before deployment. This preliminary training action enables the model to automatically recognize complex patterns and make reliable predictions when applied to new samples. The pre-trained system achieves clinical-grade reliability by learning from diverse training data, handling the complexity of accurate prediction through advance preparation rather than during actual sample analysis.
