Sample Holder Advancing Mechanism Pushing Portion Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional automatic sample introduction apparatuses in biomedical examination systems face challenges when new sample holders are added, as they can lead to sample falling or pouring issues, requiring pauses in the sample holder advancing mechanism and detection operations.
Innovation Solution
A continuous sample introduction method and apparatus that uses a pushing portion to abut against the side wall of sample holders during movement, allowing for seamless integration of new sample holders without pausing the mechanism or detection operations, utilizing a control device to manage the advancing and returning operations between initial and limiting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a new sample holder is additionally placed into the sample loading device while the sample holder advancing mechanism is moving, then the sample introduction operation can continue without pausing, but there may be hidden dangers or failures such as falling and pouring of the sample in the sample holder
Solution Approach 1:
The control device controls the sample holder advancing mechanism to perform a returning operation before a new sample holder is added. The pushing portion moves to a safety position away from the sample holder, creating a safe state that prevents sample spillage when the new sample holder is introduced. This preliminary action eliminates the risk before the potentially harmful event occurs.
2Reliability
If the sample holder advancing mechanism pauses during sample introduction to prevent sample falling, then sample safety is improved, but the detection operation efficiency decreases
Solution Approach 1:
The sample holder advancing mechanism operates continuously without pausing during sample introduction. By controlling the pushing portion to move to a safety position and then automatically returning to the pushing position after the new sample holder is added, the system maintains continuous operation, preventing both sample spillage and operational interruptions.
3Reliability
If the pushing portion remains in contact with the sample holder during movement, then the sample holder is reliably pushed, but collisions may occur when new sample holders are added
Solution Approach 1:
The sample holder advancing mechanism dynamically adjusts the position of the pushing portion. During normal operation, the pushing portion contacts the sample holder for reliable pushing. When a new sample holder is added, the control device automatically moves the pushing portion to a safety position away from the sample holder, then returns it to the pushing position. This dynamic adjustment eliminates collision risk while maintaining pushing reliability.

AI summary
A continuous sample introduction method is provided. The method includes controlling a current sample holder advancing mechanism to perform an advancing operation according to a sample introduction trigger signal, so that the current sample holder advancing mechanism moves in a direction from an initial position to a limiting position, and during the movement, a pushing portion of the current sample holder advancing mechanism is capable of abutting against a side wall of a sample holder in a current sample loading device; controlling the current sample holder advancing mechanism to perform a returning operation when the current sample holder advancing mechanism moves to the limiting position, and during the movement, the pushing portion is capable of avoiding contacting with the sample holder; and the current sample holder advancing mechanism automatically repeats the advancing operation and the returning operation when the current sample holder advancing mechanism moves to the initial position.
