Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual preprocessing is performed on specimens, then specimen preparation can be completed, but errors occur during the preprocessing step
Solution Approach 1:
The patent replaces manual preprocessing operations with an automated imaging system that captures images of specimens and uses image analysis to automatically determine preprocessing status, eliminating human error in the preprocessing determination step
Solution Approach 2:
The system enables self-service by automatically detecting and determining preprocessing status through image analysis, where the specimen processing state is assessed without requiring operator intervention or visual determination
2Ease of operation
If automated image analysis is used to detect specimen status, then operator workload is reduced, but preprocessing errors still occur
Solution Approach 1:
The patent implements feedback by capturing images of specimens after preprocessing, analyzing these images to determine whether preprocessing was performed correctly, and providing this information back to the analysis system to decide whether to proceed with analysis or reject the specimen
Solution Approach 2:
The system performs preliminary action by capturing images and analyzing preprocessing status before the main analysis procedure, allowing for early detection and rejection of defective specimens to prevent errors in subsequent analysis
3Device complexity
If visual determination by operator is used, then simple determination can be made, but errors and workload increase
Solution Approach 1:
The patent substitutes the operator's visual determination with an automated image analysis system that objectively measures specimen characteristics, eliminating subjective judgment and human error while maintaining simplicity through automated processing

AI summary
An object of the invention is to provide an automatic analyzer that reduces an error specimen caused by a preprocessing step and reduces a workload of an operator. For this purpose, the invention provides an automatic analyzer for analyzing a specimen, the automatic analyzer including: a preprocessing registration information acquisition unit configured to read or receive, for each specimen, preprocessing registration information for specifying a preprocessing execution source that performs preprocessing on the specimen or a preprocessing date and time at which preprocessing is performed on the specimen; an error determination unit configured to determine, for each specimen, presence or absence of occurrence of an error caused by the preprocessing; and a statistical data output unit configured to statistically output an error occurrence status for each preprocessing execution source or preprocessing date and time.
