Solution Overview
Problem
Existing water toxicity monitoring systems are limited by their inability to analyze multiple samples simultaneously with high precision and accuracy, and they require significant time for analysis, making them unsuitable for rapid intervention in unexpected water contamination events. Additionally, these systems are prone to cross-contamination and fouling due to hydraulic handling of microorganisms.
Innovation Solution
A device based on random access technology that allows for continuous, autonomous monitoring and analysis of multiple samples simultaneously, using a reaction tray with luminometric and fluorimetric modules for rapid measurement and a mechanical arm for precise handling and washing, reducing the risk of contamination and fouling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If flow technology analyzers are used for automated toxicity monitoring, then automation is achieved, but multiple samples cannot be analyzed simultaneously and analysis time is extended
Solution Approach 1:
The device divides the analysis system into multiple independent measurement chambers (at least two chambers) that can simultaneously analyze different samples. Each chamber operates independently with its own flow path, allowing parallel processing of multiple samples without cross-contamination, thus increasing productivity while maintaining automation.
Solution Approach 2:
The invention transitions from sequential single-sample analysis to parallel multi-sample analysis by adding spatial dimensionality through multiple measurement chambers. This dimensional expansion allows simultaneous analysis of multiple samples along the time axis, resolving the contradiction between automation and productivity.
2Extent of automation
If hydraulic handling of microorganisms is used in flow analyzers, then automated analysis is achieved, but cross-contamination and fouling occur
Solution Approach 1:
The system segments the hydraulic flow paths into separate, isolated channels for each measurement chamber. Each chamber has its own dedicated inlet and outlet ports, preventing cross-contamination between samples while maintaining automated hydraulic handling. The physical separation ensures that microorganisms in different chambers cannot mix.
Solution Approach 2:
The invention introduces separate hydraulic intermediaries (individual pumps and flow control mechanisms) for each measurement chamber. These intermediaries manage the hydraulic handling of microorganisms independently, ensuring automated operation while preventing fouling and cross-contamination through isolated flow paths.
3Measurement precision
If manual analysis methods are used with luminometers, then measurement precision is maintained, but analysis time is extended and operator involvement is required
Solution Approach 1:
The invention merges multiple measurement chambers into a single integrated device with unified control systems. This consolidation allows simultaneous analysis of multiple samples while maintaining the precision of individual luminometric measurements. The combined system eliminates the need for sequential manual analysis, reducing total analysis time while preserving measurement accuracy through standardized measurement protocols.
Solution Approach 2:
The device enables continuous automated analysis by maintaining constant flow of microorganisms through multiple measurement chambers. The hydraulic system ensures uninterrupted measurement sequences, eliminating idle time between samples while preserving measurement precision through consistent flow conditions and standardized measurement protocols.
