Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers face issues where residual reagents in the mixed liquid chamber affect the creation of new mixed liquids, leading to inaccurate analysis results.
Innovation Solution
The automatic analyzer introduces a relaxation reagent into the mixed liquid chamber based on the characteristics of the residual reagent, neutralizing or diluting its effects to ensure accurate subsequent processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a new mixed liquid is created in the mixed liquid chamber, then the analysis process can proceed, but the residual liquid from the previous mixed liquid affects the accuracy of the new analysis
Solution Approach 1:
The relaxation reagent is introduced into the mixed liquid chamber before the new reagent to pre-neutralize the residual liquid from the previous analysis. This preliminary action ensures that when the new reagent is introduced, the chamber is already in a state that will not interfere with the new analysis, thus maintaining high accuracy without sacrificing throughput
Solution Approach 2:
The relaxation reagent acts as an intermediary substance between the residual liquid from the first mixed liquid and the new reagent. It chemically neutralizes the residual liquid's effects, creating a neutral environment that allows the new reagent to function accurately without interference from previous substances
2Loss of time
If the mixed liquid chamber is not thoroughly cleaned between analyses, then the analysis process is faster, but the residual reagent contaminates the next analysis
Solution Approach 1:
The relaxation reagent serves as a chemical intermediary that neutralizes residual reagents without requiring physical removal or extensive flushing. This chemical neutralization approach eliminates contamination risks while maintaining rapid analysis cycling, as the relaxation reagent can be introduced quickly and neutralizes contaminants in-situ
3Measurement precision
If a relaxation reagent is introduced to neutralize residual liquid, then the accuracy of subsequent analysis is improved, but an additional step is added to the process
Solution Approach 1:
The introduction of the relaxation reagent is merged with the existing reagent introduction process. The relaxation reagent is delivered through the same reagent introduction mechanism that introduces the analysis reagents, and its delivery is controlled by the same control unit. This integration means no additional physical hardware or separate operational sequence is needed, adding minimal complexity while significantly improving accuracy
