Analyzer Specimen Container Detection and Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analyzers require manual rotation of specimen container holders to accommodate different types of specimen containers, which is burdensome for users.
Innovation Solution
An analyzer with a specimen container setting portion that includes multiple container holders, a sensor for detecting the presence of specimen containers, and a controller to automatically determine the correct holder position and move the container to the aspiration position based on sensor detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual rotation of specimen container holder is used to accommodate different types of specimen containers, then the device can handle multiple container types, but the user burden increases and operation becomes cumbersome
Solution Approach 1:
The system performs self-service by automatically detecting the specimen container type and positioning it correctly without requiring user intervention. The detection unit identifies container characteristics and the control unit automatically adjusts the holder position, allowing the system to serve itself rather than requiring manual user actions.
Solution Approach 2:
The manual mechanical rotation operation is replaced by an automated detection and control system. The detection unit (optical or sensor-based) substitutes for manual visual inspection, and the automated control unit replaces manual rotation commands, transforming a mechanical user-operated system into an automated electromechanical system.
2Device complexity
If manual rotation of specimen container holder is required, then the structure remains simple, but the operation time increases and productivity decreases
Solution Approach 1:
The system performs preliminary detection of the specimen container type before the aspiration process begins. The detection unit scans and identifies container characteristics in advance, allowing the control unit to pre-position the holder correctly, so that when the aspiration operation starts, everything is already in place, eliminating delays during the actual specimen processing.
Solution Approach 2:
The detection unit provides feedback information about the specimen container type and position to the control unit. This feedback loop allows the system to automatically adjust and optimize the holder positioning based on real-time detection data, ensuring correct positioning without manual intervention and maintaining high processing speed.
3Device complexity
If the specimen container holder is fixed in position, then the structure is simple, but the system cannot adapt to different container types
Solution Approach 1:
The specimen container holder transitions from a fixed static position to a dynamic adjustable position. The holder can be automatically rotated or repositioned based on the detected container type, allowing the system to adapt to different container configurations while maintaining structural simplicity through automated control rather than complex mechanical designs.
