Specimen Dilution Container With Second Bottom Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biological sample analysis, the existing containers fail to ensure sufficient mixing of the sample and diluting solution at specific positions, leading to incomplete dilution and inaccurate analysis results.
Innovation Solution
A container with a second bottom and a groove on the inner side wall, designed to hold the sample and facilitate mixing by allowing the diluting solution to be injected and mixed effectively, promoting homogeneous dilution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the biological sample is dropped onto various positions (bottom or inner side wall), then the container can accommodate the sample, but the sample and diluting solution are not sufficiently mixed at some positions
Solution Approach 1:
The patent applies local quality by creating a specific region (second bottom) with different properties from the rest of the container. This localized area is designed to hold the biological sample and facilitate effective mixing with the diluting solution, ensuring uniform mixing regardless of where the sample is initially dropped into the container.
Solution Approach 2:
The second bottom acts as an intermediary structure between the sample and the diluting solution. It provides a dedicated interface where the sample is held and where the diluting solution effectively contacts and mixes with the sample, mediating the mixing process to ensure homogeneity.
2Measurement precision
If the container has a simple structure, then it is easy to manufacture, but it cannot ensure sufficient mixing of sample and diluting solution
Solution Approach 1:
Rather than making the entire container complex, the patent applies local quality by adding only a specific localized feature (the second bottom) to the otherwise simple container structure. This localized modification provides the necessary mixing functionality without significantly increasing overall device complexity.
Solution Approach 2:
The container interior is segmented into different functional zones: the first bottom for general support and the second bottom for sample holding and mixing. This segmentation allows each zone to perform its specific function optimally while keeping the overall structure relatively simple.

AI summary
Provided is a container for preparing a diluted solution of a biological sample to be used for biological sample analysis. Specifically, provided is a container for specimen dilution, including: an open; a first bottom; a second bottom formed on an inner side wall of the container; and a groove upwardly formed, on the inner side wall of the container, from the second bottom, in which the groove has a constant width equal to a width of the second bottom, or the groove has, at a lower end thereof, a width equal to the width of the second bottom and upwardly widens.
