Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid collection cups often fail to allow for full extraction of fluid, which can limit their effectiveness in medical procedures such as artificial insemination.
Innovation Solution
A sample collection cup with an inner surface profile designed to direct fluid into an accumulation area, combined with a syringe system that includes a nub for tactile feedback and a plunger for efficient fluid extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional collection cup is used, then the cup can collect fluid, but the fluid cannot be fully extracted from the cup
Solution Approach 1:
The collection cup incorporates a curved inner surface with a specific profile that guides fluid toward the base, replacing flat or irregular surfaces. This curvature ensures fluid flows smoothly to the extraction point, enabling complete removal by syringe while maintaining ease of operation.
Solution Approach 2:
The invention modifies the geometric parameters of the collection cup's inner surface, specifically creating a profile with defined curvature and slope angles. These parameter changes optimize fluid flow characteristics, allowing 100% extraction efficiency while keeping the device simple to use.
2Quantity of substance
If the inner wall is extended inward and downward, then fluid is directed into the accumulation area, but the cup structure becomes more complex
Solution Approach 1:
The inner wall is segmented into distinct functional zones: an upper collection zone and a lower accumulation zone separated by the curved profile. This segmentation directs fluid systematically from collection to accumulation, improving efficiency without requiring multiple separate components or complex mechanisms.
Solution Approach 2:
The inner wall features a curved profile that naturally guides fluid downward into the accumulation area at the base. This curvature achieves efficient fluid direction using a simple continuous surface, avoiding complex segmented structures or mechanical elements.

AI summary
A device may include a top region defining an opening having a top diameter. A device may include a bottom region opposite the top region and defining a base. A device may include an outer wall extending from the top region to the bottom region. A device may include an inner wall coupled to the outer wall and extending inward away from the outer wall and downward toward the base, the inner wall defining an accumulation area and having a profile configured to direct fluid into the accumulation area.
