Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial insemination sheaths with plastic tips have complex manufacturing processes, inadequate semen distribution within the uterus, and high reflux rates, limiting fertilization chances due to inefficient semen dispersion and orientation.
Innovation Solution
An artificial insemination device with a tip featuring a semi-spherical end and multiple sloped orifices, allowing for better semen dispersion and compatibility with vanes of different diameters, reducing reflux and improving manufacturing simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic tip with two outlets at 90° angle is used, then the manufacturing process becomes complex, but the semen distribution and fertilization efficiency deteriorate
Solution Approach 1:
The tip is divided into multiple outlet openings (at least two) positioned at different locations and orientations. This segmentation allows semen to be distributed through multiple pathways simultaneously, improving coverage of both uterine horns while maintaining a simpler manufacturing process compared to complex angled single-outlet designs.
Solution Approach 2:
The outlet openings are positioned at different spatial locations and orientations within the tip structure. This dimensional arrangement ensures that semen is expelled in multiple directions to reach both uterine horns effectively, transforming a single-direction flow into a multi-directional distribution system.
2Device complexity
If semen exits through lateral orifices at 90 degrees, then the sheath structure is simplified, but semen distribution and diffusion inside the uterus deteriorates
Solution Approach 1:
Different regions of the tip are designed with specific outlet orientations tailored to their anatomical function. The outlets are positioned and angled to direct semen toward specific uterine regions, ensuring that each part of the tip contributes optimally to overall semen distribution based on local anatomical requirements.
Solution Approach 2:
The outlet openings utilize three-dimensional spatial arrangement with different orientations and positions. This allows the sheath to maintain structural simplicity while achieving effective semen diffusion by expelling semen in multiple directions rather than a single lateral direction.
3Device complexity
If a single frontal orifice is used, then the sheath anatomy is simplified, but semen reaches only one uterine horn reducing fertilization chances
Solution Approach 1:
The single frontal orifice is replaced with multiple outlet openings (at least two) positioned at different locations and orientations within the tip. This segmentation enables semen to be distributed toward both uterine horns simultaneously, increasing the versatility and coverage of the insemination device while maintaining relatively simple anatomy.
Solution Approach 2:
The tip with multiple outlets at different orientations serves multiple functions: it can direct semen to both uterine horns, accommodate different insertion angles, and ensure adequate coverage regardless of the specific anatomical variation. This multi-functional design increases adaptability without significantly complicating the sheath anatomy.
4Speed
If high reflux rate occurs during quick jet insemination, then the insemination speed is improved, but semen loss within the sheath increases
Solution Approach 1:
Multiple outlet openings are positioned along the tip to create multiple exit pathways for semen. This segmentation reduces pressure buildup and minimizes reflux by allowing semen to escape through multiple channels simultaneously, reducing the likelihood of semen being trapped and refluxing back into the sheath during quick jet insemination.
Solution Approach 2:
The outlet openings are positioned at different orientations and locations to create multi-directional semen flow. This dimensional arrangement ensures that semen is efficiently expelled in various directions, reducing the formation of high-pressure zones that cause reflux and minimizing semen loss within the sheath during rapid administration.

AI summary
It refers to an artificial insemination device which comprises a tube and a tip engageable at one end of the tube, the tip being formed by a hollow tubular body with a semi-spherical upper end provided with at least three orifices; the tip internally comprises at least a first frustoconical portion tapering towards the upper end for insertion of a first vane containing biological material to be inseminated, followed by a first annular portion for coupling this vane, a second frustoconical portion tapering toward the upper end, arranged next to the first annular portion for insertion of a second vane containing biological material having a smaller diameter than the first vane, a second annular portion, arranged after the second additional frustoconical portion, for coupling with the second vane smaller than the first one, and a niche in the region of the upper semi-spherical end where the at least three orifices are arranged.
