Automatic Analyzer Maintenance Priority Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of automatic analyzers is complex and inefficient, with multiple consumables and operations requiring periodic replacement and operator involvement, making it difficult to prioritize and execute maintenance tasks effectively without omission.
Innovation Solution
The automatic analyzer employs a barcode system for reagents and samples, coupled with a microcomputer-controlled operation and display unit, to manage maintenance schedules, prioritize tasks, and involve operators as needed, allowing for efficient execution of maintenance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple maintenance tasks are managed with individual execution times, then maintenance accuracy is improved, but device complexity increases
Solution Approach 1:
The maintenance management system segments maintenance tasks into different priority levels (first priority for expired maintenance, second priority for approaching expiration, third priority for scheduled maintenance). This segmentation allows the system to manage multiple maintenance tasks with individual execution times without overwhelming complexity, as each task is categorized and handled according to its priority level.
Solution Approach 2:
The automatic analyzer performs self-diagnosis and self-management of maintenance tasks. The system automatically tracks execution times, determines priority levels, and manages the scheduling of maintenance operations without requiring external intervention. This self-service capability simplifies the overall management complexity while maintaining accurate tracking of individual maintenance tasks.
2Reliability
If multiple maintenance operations are executed, then reliability is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary identification and prioritization of maintenance tasks before execution. By determining priority levels in advance (expired, approaching expiration, scheduled), the system prepares the maintenance schedule optimally, allowing efficient execution without unnecessary delays. This preliminary action ensures that critical maintenance is addressed first, maintaining reliability while minimizing total time loss.
Solution Approach 2:
The maintenance management system operates continuously, automatically monitoring execution times and updating priority levels without interruption to analyzer operation. This continuous management allows maintenance tasks to be executed efficiently in priority order without causing downtime or interrupting the useful action of the analyzer, thereby maintaining reliability while minimizing time loss.
3Ease of operation
If operator involvement is required for maintenance, then ease of operation is improved, but productivity decreases
Solution Approach 1:
The priority determination unit acts as an intermediary between the automatic maintenance system and the operator. It automatically determines priority levels and presents them to the operator in a clear, organized manner, making it easy for the operator to understand which tasks to perform first. This intermediary function maintains productivity by automating the decision-making process while still requiring operator execution, thus balancing ease of operation with execution efficiency.

AI summary
The present invention realizes an automatic analyzer in which required maintenance can be executed efficiently, without omission. An operation control unit 3 controls operations of an analysis module (ISE, AU1, AU2) including a sample vessel transport mechanism 2, a reagent vessel transport mechanism 26, a reaction vessel transport mechanism 9, a sample dispensing mechanism 5, and a reagent dispensing mechanism 8, and of a display unit 18, and analyzes a sample accommodated in a reaction vessel 6. The operation control unit 3 stores a validity period for each maintenance item of the analysis module (ISE, AU1, AU2) and an execution time for each maintenance item in a memory 25, displays an execution time together with an identification representation of execution priority level based on the expiration dates on the display unit 8, rearranges the display order of the maintenance items on the basis of the execution priority level, in accordance with an operator's instruction inputted through an operation input portion 21, and displays the rearranged maintenance items on the display unit 8.
