Reaction Cuvette Loading Device Vertical Return Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reaction cuvette loading devices occupy excessive space due to the movement range of the push rod, leading to a large volume and inefficient operation in chemiluminescence immunoassay apparatus.
Innovation Solution
Incorporation of a guiding control block that allows the push rod to return above the reaction cuvette, reducing its movement range and duration, and utilizing an inclined transmission groove to prevent cuvette crashes, along with a top blocking surface to control cuvette movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push rod moves horizontally to bypass the reaction cuvette, then the cuvette can be pushed to the next position, but the movement range occupies at least two cuvette positions causing huge overall volume
Solution Approach 1:
The push rod's return path is changed from horizontal to vertical by introducing a guiding control block with an arch-shaped groove. The push rod moves upward along the arch-shaped groove to bypass the reaction cuvette vertically instead of horizontally, reducing the horizontal space occupied to less than one cuvette position while maintaining the cuvette pushing function
2Volume of stationary object
If the push rod movement range is reduced to less than two cuvette positions, then the device volume is reduced, but the push rod must return above the cuvette which requires precise control
Solution Approach 1:
A guiding control block is introduced as an intermediary component between the push rod and the reaction cuvette. This block contains an arch-shaped groove that guides the push rod's movement path, providing precise control for the push rod to return above the cuvette without requiring complex control mechanisms
Solution Approach 2:
The guiding control block introduces a vertical dimension to the push rod's return path through the arch-shaped groove, allowing the push rod to bypass the cuvette in the vertical direction rather than requiring extended horizontal movement, thus reducing device volume while maintaining simplicity
