Automatic Analysis Device Dynamic Maintenance Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic analysis devices face challenges in optimizing the frequency of maintenance such as periodic cleaning and replacement of passages that come into contact with specimens or reagents, as existing methods rely on standard analysis conditions rather than specific properties of the specimen or analysis protocol, leading to suboptimal usability and analysis performance.
Innovation Solution
An automatic analysis device equipped with a control device that assesses the properties of specimens, reagents, and analysis protocols to determine the necessity of maintenance, outputting recommendations for periodic cleaning or replacement based on the number of dispensing, feeding, and measuring operations, ensuring adequate maintenance frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic cleaning or replacement is performed based on standard analysis conditions, then maintenance frequency is predetermined, but it becomes too frequent or too infrequent depending on specific analysis conditions
Solution Approach 1:
The maintenance frequency is made dynamic by calculating a maintenance index based on actual measurement data including specimen properties, reagent properties, and number of measurements. This allows the maintenance schedule to adapt automatically to different analysis conditions rather than following a fixed predetermined schedule, resolving the contradiction between maintaining reliable performance and ensuring ease of operation.
Solution Approach 2:
The system implements feedback by continuously monitoring measurement data and using it to calculate the maintenance index. This feedback loop allows the system to adjust maintenance timing based on actual usage patterns and specimen characteristics, preventing both excessive and insufficient maintenance while optimizing both reliability and usability.
2Reliability
If maintenance is performed frequently to ensure analysis performance, then analysis performance is maintained, but usability deteriorates due to excessive maintenance interruptions
Solution Approach 1:
The system performs self-assessment by automatically calculating the maintenance index based on its own measurement data without requiring external judgment. This enables the system to determine the optimal maintenance timing autonomously, minimizing unnecessary maintenance interruptions while ensuring analysis performance is maintained, thus reducing time loss without sacrificing reliability.
3Device complexity
If maintenance is performed based on standard conditions without considering specific specimen properties, then maintenance schedule is simple, but analysis performance deteriorates due to inadequate maintenance timing
Solution Approach 1:
The system changes the parameter basis for maintenance scheduling from fixed standard conditions to dynamic parameters including specimen properties, reagent properties, and measurement count. By calculating the maintenance index based on these variable parameters, the system achieves accurate maintenance timing that adapts to different analysis conditions while maintaining a relatively simple operational interface.
