Angled Tube Holder for Microscopic Sample Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for preimplantation embryo genetic testing face challenges in sample transfer due to limited dexterity and difficulty in matching samples with corresponding tubes, leading to errors in sample identification and misdiagnosis.
Innovation Solution
A device that holds tubes at an angle, allowing for improved handling and control during sample transfer, with a drop of media placed on the lower wall for visual confirmation and a label on the device for easy identification, enabling correct sample placement and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tube is held horizontally for sample transfer, then the operator can easily hold the tube, but the operator's ability to focus the microscope on the sample is limited
Solution Approach 1:
The tube holder positions the tube at an angled orientation rather than horizontal, changing the spatial dimension of tube placement. This angle allows the operator to focus the microscope on the sample while maintaining easy tube handling, resolving the contradiction between ease of operation and detection difficulty
2Measurement precision
If the tube is made small to match sample numbers, then sample identification is easier, but the number on the tube cannot be readily observed under the microscope
Solution Approach 1:
The number is positioned on the outer surface of the tube rather than inside, utilizing the external dimension for identification. This allows the number to be observed under the microscope without obstructing the view inside the tube, while still maintaining small tube size for precise sample matching
3Ease of operation
If the tube wiggles considerably during transfer, then the tube is easy to hold, but precise sample placement control is reduced
Solution Approach 1:
The tube holder stabilizes the tube at a fixed angle, eliminating horizontal movement and wiggling. This angular positioning provides both easy tube handling and precise sample placement control, as the tube remains stationary during the transfer process

AI summary
The non-vertical tube holder enables visual control for transferring a microscopic sample into the test-tube, decreasing the chance of the sample loss. The tube holder may also be used for a tube transportation to the sample testing facility.
