An automatic analysis device that sets and displays specific check items based on operator skill levels, ensuring all necessary checks are confirmed before starting analysis, preventing errors and ensuring accurate measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator-dependent visual checks are used before analysis start, then device operation flexibility is maintained, but measurement reliability deteriorates due to missed check items
Solution Approach 1:
The device performs self-checks automatically before analysis start, including verifying water temperature, photometer light quantity, and reagent levels. This eliminates dependency on operator skill for these critical checks, ensuring measurement reliability while maintaining operational simplicity.
Solution Approach 2:
The system provides automated feedback to the operator through the display unit, showing the status of each check item (normal or abnormal). This feedback mechanism guides the operator through necessary checks without requiring expert knowledge, improving both reliability and ease of operation.
2Measurement precision
If automated consistency checks for analysis parameters are implemented, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
The system performs consistency checks for analysis parameters (prozone parameters, calibration parameters) automatically before analysis start. This preliminary verification ensures measurement precision without requiring complex manual verification procedures, as the checks are integrated into the startup sequence.
Solution Approach 2:
Multiple check functions (parameter consistency verification, water temperature check, photometer check, reagent level check) are merged into a single integrated check execution unit. This reduces device complexity by consolidating what could be separate complex systems into one unified module that manages all pre-analysis checks.
3Reliability
If comprehensive pre-analysis checks are performed manually, then measurement reliability improves, but analysis start time increases
Solution Approach 1:
The check execution unit operates continuously and automatically through the analysis startup process, performing all necessary checks (water temperature, photometer, reagent levels, parameter consistency) without interrupting the workflow. This eliminates time loss associated with manual checking while maintaining measurement reliability through comprehensive verification.

AI summary
Disclosed is an automatic analysis device in which a check item at a time of an analysis start can be set in accordance with a skill level of an operator, an analysis can be performed after the check item being displayed and confirmed, and erroneous measurement caused due to a missed check can be prevented. The check item such as checking the remaining quantity of a reagent or the like displayed in a check screen before the analysis start can be set for each type of operator, each day, each time. The set check item is configured to be displayed in a screen before the analysis start, and unless the operator confirms the check item, the analysis start is not allowed in principle. An automatic analysis device which can prevent erroneous measurement caused due to a missed check of the operator before the analysis start is realized.
