Sample Analyzer Lock Mechanism for Irregular Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sample processing apparatuses connected to transportation lines face operational disruptions due to irregular sample delivery times, leading to suspended operations and potential misalignment of moving mechanisms, which complicates smooth sample processing.
Innovation Solution
A sample analyzer with a lock mechanism for the body cover that automatically adjusts between locked and unlocked states based on operational modes, preventing unnecessary repositioning of moving mechanisms during irregular sample delivery intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sample processing apparatus is connected to a transportation line with irregular sample delivery intervals, then the apparatus can receive samples from multiple sources, but the operation is frequently suspended and moving mechanisms are displaced
Solution Approach 1:
The system performs preliminary actions by detecting cover opening status before sample arrival and proactively returning moving mechanisms to original positions. The controller monitors cover sensor signals and preemptively repositions mechanisms to prevent displacement, rather than waiting for displacement to occur.
Solution Approach 2:
The system implements feedback through cover sensors that detect whether the cover is opened or closed, and this information is fed back to the controller. The controller uses this feedback to determine when to return moving mechanisms to their original positions, creating a closed-loop control system that responds to actual operational states.
2Ease of operation
If the cover is made openable for reagent replacement and maintenance, then user accessibility is improved, but moving mechanisms may be displaced during suspension periods
Solution Approach 1:
Cover sensors provide feedback to the controller about the cover's open/closed state. When the cover is detected as opened, the controller knows to return moving mechanisms to their original positions before closing the cover, ensuring positioning accuracy is maintained while still allowing user access for maintenance.
Solution Approach 2:
The system automatically monitors cover status and self-corrects moving mechanism positions without requiring user intervention. The controller autonomously detects cover opening and initiates the return-to-origin sequence, making the system self-aware and self-correcting regarding mechanism positioning.
3Manufacturing precision
If the moving mechanism is returned to original position every time a sample is transported, then positioning accuracy is maintained, but processing time is increased due to frequent repositioning operations
Solution Approach 1:
The system performs the repositioning action preliminarily - detecting cover opening status and initiating return-to-origin sequences before the next sample arrives. This prevents displacement from occurring in the first place, eliminating the need for corrective repositioning after displacement happens.
Solution Approach 2:
The cover sensor feedback system allows the controller to make intelligent decisions about when repositioning is actually necessary. By monitoring cover status, the system only repositions mechanisms when the cover has been opened, avoiding unnecessary repositioning operations and reducing time loss.

AI summary
A sample processing apparatus includes: a sample processing unit comprising a moving mechanism and configured to perform a sample processing operation by moving the moving mechanism; a cover configured to cover the moving mechanism of the sample processing unit; a lock mechanism configured to lock the cover to prevent the cover from being opened; and a controller configured to control the lock mechanism, wherein the controller is configured to set either of a first mode and a second mode, wherein in the first mode, the cover is kept locked after the sample processing unit has completed the sample processing operation until an instruction to unlock the cover is received from a user, and in the second mode, the cover is automatically unlocked after the sample processing unit has completed the sample processing operation.
