Specimen Processing Apparatus Position Verification During Reagent Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzing apparatuses for specimens like blood and urine face the risk of malfunction during reagent container replacement due to user contact with movable sections, potentially causing errors in measurement operations.
Innovation Solution
A specimen processing apparatus with a movable section that includes a detector for tracking displacement and a controller to determine if the section was moved during a stop, allowing for controlled preparation and restart of operations without malfunctions, ensuring the movable section returns to a precise original position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable section is stopped during reagent container replacement, then user safety and replacement ease are improved, but the risk of user contact-induced movement and subsequent malfunction increases
Solution Approach 1:
The system performs preliminary actions by saving the stop position information before the movable section is stopped and preparing operations are executed. This allows the system to restore the movable section to its correct position after user intervention, preventing malfunction while maintaining ease of replacement operation.
Solution Approach 2:
The detector provides feedback about the movable section's position during and after the stop period. The controller uses this feedback information to determine whether the movable section was moved by user contact, and accordingly adjusts the preparing operations to ensure proper positioning before restarting the measurement operation.
2Device complexity
If the movable section position is not verified after stop, then system complexity is reduced, but measurement precision and operation reliability deteriorate
Solution Approach 1:
The system performs preliminary position verification by comparing the stop position information with the actual position after the stop period. This preliminary check ensures that the movable section is at the correct position before starting the measurement operation, maintaining measurement precision without requiring continuous complex monitoring.
3Productivity
If preparing operations are performed regardless of movement, then operation speed is maintained, but malfunction risk increases due to incorrect position assumptions
Solution Approach 1:
The system dynamically adjusts the preparing operations based on the determination result. When the movable section is detected to be at the correct position, standard preparing operations are performed. When movement is detected, the system modifies the preparing operations to first restore the correct position, ensuring reliability while minimizing impact on operation speed.
