Multi-Tube Handling Device for Simultaneous Lab Cap Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laboratory test tubes with integral snap-type sealing caps require individual handling for opening, filling, or emptying, which is time-consuming and inefficient.
Innovation Solution
A manually operated device that allows multiple test tubes to be simultaneously opened, held open for filling or emptying, and closed for sealing, featuring a top plane with color indicators, lifting devices, and a sliding mechanism for easy operation, accommodating 10 to 12 test tubes with integral snap-type sealing caps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual handling of test tubes is used for opening, filling, and closing, then each operation can be performed carefully, but the process is time-consuming and inefficient
Solution Approach 1:
The patent combines multiple test tube handling operations into a single integrated device. The rack holds multiple test tubes simultaneously, the lid assembly covers all tubes at once, and the sliding plate can engage all caps together. This merging of functions allows simultaneous opening, filling, and closing of multiple tubes, dramatically improving productivity while keeping the device structure manageable through modular design elements.
2Loss of time
If multiple test tubes are handled simultaneously, then time and effort are reduced, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into distinct functional modules: a rack for holding tubes, a lid assembly for covering tubes, a sliding plate for engaging caps, and individual levers for opening and extracting. Each module performs a specific function, allowing simultaneous operation on multiple tubes without requiring an overly complex integrated mechanism. This segmentation reduces overall device complexity while enabling parallel handling of multiple test tubes.
Solution Approach 2:
The sliding plate serves multiple functions: it can engage all test tube caps simultaneously for closing, can be positioned to open all caps at once, and works with tubes of various sizes through its design. The lid assembly similarly provides universal coverage for multiple tubes. This multi-functionality allows a single device structure to handle various operations on multiple tubes, reducing the need for separate specialized devices and thereby reducing overall complexity.
3Productivity
If the lid assembly is designed to open all caps simultaneously, then efficiency is improved, but the mechanism requires more components
Solution Approach 1:
The test tube caps are designed with integral hinges that allow them to be opened by a simple lifting motion of the lid assembly. The caps self-open as the lid is lifted, without requiring separate mechanisms for each cap. Similarly, the spring-loaded pins automatically engage with the cap notches when the sliding plate is moved, and the open lever uses spring assistance to reduce the effort needed to lift the lid. This self-service design enables simultaneous operation of multiple caps while minimizing the number of active components required.
