Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nucleic acid amplification processes lack adequate controls for abnormal fluorescence detection, leading to unreliable results due to equipment failures in fluorescence detection systems.
Innovation Solution
Implementing a method to monitor fluorescence signals during nucleic acid amplification by measuring intensities at multiple time points and comparing them to a predetermined threshold, detecting abnormal fluorescence if the intensity falls below this threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluorescence-based detection methods are used to monitor nucleic acid amplification, then real-time tracking of amplicon production is achieved, but equipment failures can lead to unreliable results and false negatives
Solution Approach 1:
The patent applies preliminary action by establishing baseline fluorescence measurements before the amplification reaction begins and setting control thresholds in advance. This allows the system to proactively detect deviations from normal operation during the reaction, enabling early identification of equipment failures rather than waiting for abnormal results to manifest.
Solution Approach 2:
The patent implements feedback mechanisms by continuously monitoring fluorescence signals during amplification and comparing them against predetermined control thresholds. When deviations are detected, the system provides feedback that triggers alerts or repeat measurements, creating a closed-loop control system that maintains reliability by correcting or flagging potential equipment failures in real-time.
2Productivity
If existing amplification assays are run without adequate process controls, then productivity is maintained, but equipment failures go undetected leading to wasted reagents and false negatives
Solution Approach 1:
The patent applies self-service by enabling the amplification system to autonomously monitor its own performance through built-in control mechanisms. The system automatically detects equipment failures, triggers alerts, and can initiate repeat measurements without external intervention, allowing continuous operation and maintaining productivity while preventing reagent waste through early failure detection.
3Device complexity
If fluorescence detection is performed without process controls, then device complexity is minimized, but abnormal fluorescence detection cannot be identified
Solution Approach 1:
The patent applies universality by designing control mechanisms that leverage the existing fluorescence detection infrastructure to perform dual functions: normal amplicon monitoring and equipment failure detection. By using the same fluorescence channel and detection hardware for both purposes, the system enhances functionality without adding separate complex detection subsystems.
