Automatic Analyzer Sample Positioning Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers require operators to manually preset the arrangement positions of calibrators and controls, which can lead to errors, especially for inexperienced operators, and result in inaccurate measurements.
Innovation Solution
An automatic analyzer that includes a sample-container array unit, a display unit, an input unit, and a control unit. The control unit automatically determines the arrangement position of a sample necessary for measurement by referring to the selected measurement content and availability information, and presents this position to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator manually presets the arrangement positions of calibrators and controls, then the measurement process can be initiated, but operator errors occur leading to inaccurate measurements
Solution Approach 1:
The system automatically determines and assigns arrangement positions for calibrators and controls without requiring manual operator input. The control unit autonomously queries availability information from the storage unit and specifies positions based on predetermined rules, eliminating operator errors while maintaining ease of use.
Solution Approach 2:
The manual mechanical process of operator positioning is replaced by an automated information processing system. The control unit retrieves availability data from storage, processes it according to arrangement rules, and automatically determines positions, substituting human judgment with automated computational logic.
2Reliability
If the operator presets arrangement positions for all calibrators and controls, then complete measurement coverage is achieved, but the number of settings increases making the system complex
Solution Approach 1:
The system extracts only the essential information needed for position assignment - availability status of positions - from the complete configuration data. By querying only availability information rather than managing all possible position settings, the system reduces complexity while ensuring measurement completeness through automated assignment.
3Measurement precision
If calibration measurement is performed frequently to maintain accuracy, then measurement precision is improved, but the time required for preparation increases
Solution Approach 1:
The system performs preliminary automated determination of arrangerment positions before calibration measurement begins. By pre-querying availability information and pre-specifying positions according to predetermined rules, the system prepares the measurement configuration in advance, reducing the time required during actual calibration operations.

AI summary
An automatic analyzer includes a control unit that performs a process when a sample necessary to perform measurement for measurement content selected on an item selection screen is not arranged in a sample-container array unit. The process includes referring to the measurement content selected on the item selection screen and availability information that is information indicating whether each position in the sample-container array unit is available. A position in the sample-container array unit at which a container containing the sample necessary to perform measurement for the selected measurement content is to be arranged is specified in accordance with a specified arrangement rule, and information on the specified position in the sample-container array unit is displayed on a display unit.
