Reaction Disc Washing Control for Analysis Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic analysis devices face challenges in efficiently performing soaking and washing of reaction containers without hindering the analysis process, especially in facilities operating 24/7, where securing time for soaking and washing during urgent sample analysis is not guaranteed, leading to potential degradation in analysis efficiency.
Innovation Solution
The device incorporates a control system that allows for concurrent or delayed initiation of the soaking and washing process during the analysis preparation phase, using a dispensing mechanism to distribute soaking and washing detergent to reaction containers, ensuring efficient washing without interrupting the analysis cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soaking and washing are performed during standby period, then washing quality is improved, but analysis efficiency deteriorates when urgent samples arrive
Solution Approach 1:
The system performs preliminary washing actions during idle periods by storing washing information and executing it when the analysis device becomes idle. This allows the washing process to be prepared in advance without interrupting ongoing analysis operations, resolving the conflict between washing quality and analysis efficiency.
Solution Approach 2:
The analysis device automatically manages its own washing schedule by monitoring its own operational state and initiating washing during idle periods without external intervention. This self-service mechanism ensures washing is performed when appropriate without requiring manual scheduling that could conflict with urgent analyses.
2Reliability
If soaking and washing are forcibly completed, then washing quality is improved, but analysis process is hindered
Solution Approach 1:
The washing process is made dynamic by allowing it to be executed only when the analysis device is in an idle state. The system continuously monitors operational status and adjusts washing execution timing accordingly, ensuring that washing quality is maintained without forcing interruptions to ongoing analysis processes.
Solution Approach 2:
The system uses feedback from its own operational state to control washing execution. By monitoring whether the device is busy or idle, the system automatically determines the appropriate timing for washing, preventing interference with analysis processes while ensuring washing is performed when conditions are favorable.
3Measurement precision
If washing is performed immediately before analysis, then analysis accuracy is maintained, but accumulated dirt from repeated use cannot be removed
Solution Approach 1:
The system performs preliminary washing during idle periods before the next analysis cycle begins. By storing washing information and executing it in advance, the system removes accumulated dirt from repeated use while ensuring that analysis accuracy is maintained through proper washing, without creating timing conflicts.

AI summary
After an analysis start instruction is input in a state where a sample is not dispensed to all of reaction containers 104 mounted on a reaction disc 105, before completing an analysis preparation washing process for washing the reaction container 104 to be used in analyzing the sample to be first analyzed, a soaking and washing process for performing soaking and washing during a predetermined period of time is controlled to be started by dispensing a soaking and washing detergent to another reaction container 104 different from the reaction container 104. In this manner, the soaking and washing can be efficiently performed on the reaction container without hindering an analysis process.
