Automatic Analyzer Re-execution Logic for Consumable Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic analyzers face inefficiencies and resource wastage when maintenance processes are suspended, requiring re-execution of all steps or manual operator intervention, leading to unnecessary consumable consumption and prolonged maintenance times.
Innovation Solution
An automatic analyzer with an analyzing unit, input unit, display unit, storage unit, and control unit that stores and executes maintenance information for sequential tasks, allowing re-execution of maintenance from the suspended point with minimal essential items, reducing consumable usage and operator burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pipe functions are re-executed from the start after suspension, then all maintenance items can be completed, but consumable supply is unnecessarily consumed and maintenance time is wasted
Solution Approach 1:
The system stores execution status information of each maintenance item in advance during normal execution. When suspension occurs, this pre-stored status information enables the system to identify which items were already completed and which need re-execution, avoiding unnecessary consumption of consumables for already-completed items.
Solution Approach 2:
The system continuously monitors and stores the execution status of each maintenance item, providing feedback information about completion state. This feedback mechanism allows the control unit to make intelligent decisions about re-execution scope, ensuring that only necessary maintenance items are re-executed after suspension, thereby reducing consumable waste.
2Reliability
If pipe functions are re-executed from the start after suspension, then all maintenance items can be completed, but maintenance time is increased
Solution Approach 1:
The system pre-stores execution status information for each maintenance item during normal operation. Upon suspension and subsequent restart, this pre-stored information enables immediate identification of the resumption point, eliminating the time required to re-execute already-completed maintenance items and reducing overall maintenance time.
Solution Approach 2:
The system dynamically adjusts the re-execution scope based on stored execution status information. Instead of statically re-executing all maintenance items from the beginning, the control unit dynamically determines the optimal resumption point, adapting the maintenance process to the actual suspension circumstances and minimizing time loss.
3Loss of substance
If operator manually designates and executes maintenance items one by one after suspension, then unnecessary consumable consumption is avoided, but operator work time increases
Solution Approach 1:
The system automatically identifies the resumption point using pre-stored execution status information and autonomously determines which maintenance items need re-execution. This self-service capability eliminates the need for manual operator intervention to identify completed items, reducing operator work time while maintaining optimal consumable usage by only re-executing necessary items.
Solution Approach 2:
The system uses stored execution status information as feedback to automatically determine the appropriate resumption point and scope of re-execution. This automated feedback mechanism replaces manual operator judgment, reducing operator burden and time investment while achieving the same consumable conservation goals through systematic tracking of maintenance item completion status.
4Ease of operation
If simple re-execution of suspended maintenance items is performed, then operator work is reduced, but maintenance completeness may be insufficient
Solution Approach 1:
The system uses stored execution status information as feedback to intelligently determine the resumption point and scope of re-execution. This feedback mechanism ensures that maintenance completeness is maintained by automatically identifying which items were not completed and need re-execution, while still reducing operator burden through automated decision-making about the re-execution scope.
Solution Approach 2:
The system autonomously analyzes execution status information to determine the appropriate resumption point and re-execution scope, performing self-service maintenance management. This self-service approach ensures maintenance completeness by systematically identifying未完成 items while minimizing operator intervention, achieving both ease of operation and reliability.

AI summary
There is provided an automatic analyzer achieving both restraining unnecessary usage of a consumable supply and reducing burdens on an operator in a re-execution processing in a case where pipe functions are suspended/stopped, and being capable of completely efficiently performing an analysis preparation processing or an analysis terminating processing. In the automatic analyzer, a storage unit 25 stores information on pipe functions, and information on re-execution setting for setting a re-execution maintenance item from which re-execution is started with respect to a suspended maintenance item if pipe functions of a plurality of maintenance items are suspended halfway, and a computer 3 sequentially executes the plurality of maintenance items, based on the information on pipe functions, and re-executes maintenance from the re-execution maintenance item associated with a suspended maintenance item, based on the suspended maintenance item and the information on re-execution setting, if the pipe functions of the plurality of maintenance items are suspended halfway.
