Syringe Nub and Rounded Edges for Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional syringes used for artificial insemination often have sharp edges and corners, which can be uncomfortable and may not provide adequate tactile feedback during the procedure, leading couples to seek expensive medical solutions for fertility issues.
Innovation Solution
A fluid dispensing apparatus with a substantially cylindrical body and a nub extending from its distal end, featuring rounded edges and shapes to provide a smooth transition and tactile feedback, allowing for comfortable insertion and precise positioning against the cervix.

Engineering Contradiction Analysis
1Ease of operation
If conventional syringes with sharp edges and corners are used, then the device structure is simple and easy to manufacture, but the user comfort and tactile feedback are inadequate
Solution Approach 1:
The patent applies curvature by rounding all edges and corners of the syringe body, including the distal end, proximal end, and insertion tip. This creates a smooth, rounded contour that provides tactile feedback to the user during insertion and positioning, while eliminating sharp edges that cause discomfort. The rounded geometry maintains manufacturability through standard molding processes.
2Ease of operation
If rounded edges and shapes are implemented, then user comfort and tactile feedback improve, but manufacturing complexity increases
Solution Approach 1:
The entire syringe body is formed with rounded geometry including rounded edges at the distal end, rounded corners at the proximal end, and a rounded insertion tip. This uniform curvature approach provides consistent tactile feedback throughout the device while maintaining relatively simple manufacturing through integral molding of the rounded features.
