Segmented Injection Pipe for Artificial Insemination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injectors for artificial insemination in cows face issues with buckling of flexible tubes, leading to difficult insertion and potential uterine wall damage due to repeated contact during the injection process.
Innovation Solution
The design incorporates a guide pipe with an injection pipe that has a flexible front section and a more rigid rear section, allowing smooth insertion and reducing the risk of buckling, along with a cylindrical connector for easy fluid supply and improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire injection pipe is composed of a flexible tube, then the injection pipe can be easily manipulated, but buckling of the tube occurs when pushed out, preventing smooth insertion
Solution Approach 1:
The injection pipe is divided into two distinct sections: a flexible first pipe section at the frontal side for easy manipulation and navigation, and a rigid second pipe section at the rear side that provides structural support and prevents buckling during insertion. This segmentation allows each section to perform its specific function optimally.
Solution Approach 2:
Different parts of the injection pipe are given different mechanical properties: the frontal first pipe section is made flexible to allow bending and navigation through the guide pipe, while the rear second pipe section is made rigid to prevent buckling and ensure stable pushing force transmission during insertion.
2Measurement precision
If the injection pipe is pushed out repeatedly to achieve insertion, then the nozzle can reach deep parts of the uterus, but the inner wall of the uterus may be wounded
Solution Approach 1:
The rigid second pipe section acts as an intermediary that transmits pushing force from the operator to the flexible first pipe section and nozzle assembly. This allows the operator to push the injection pipe smoothly in a single action without repeated manipulations, thereby preventing trauma to the uterine wall while still achieving deep placement of the nozzle.
3Reliability
If a rigid pipe is used for the entire injection pipe, then buckling is prevented, but the pipe cannot be easily manipulated and inserted
Solution Approach 1:
The injection pipe is segmented into a flexible first pipe section for manipulation and a rigid second pipe section for buckling prevention. The flexible section allows the pipe to be easily inserted and navigated through the guide pipe, while the rigid section maintains structural integrity and prevents buckling during the pushing operation.
Solution Approach 2:
The injection pipe transitions from a static, uniform structure to a dynamic, multi-section structure where different parts have different degrees of flexibility. The flexible first pipe section can adapt its shape during insertion, while the rigid second pipe section maintains its form to prevent buckling, creating a dynamically responsive system.

AI summary
An injector for injecting a fertilized ovum(ova) or a sperm(s) for artificial insemination into a uterine body, by which an injection pipe can be introduced smoothly into a uterus, is disclosed. An injector for a fertilized ovum(ova) or a sperm(s) of the invention is characterized in that it comprises a guide pipe for insertion into a uterine body, an injection pipe which is inserted into the guide pipe and has a length longer than the guide pipe, and a nozzle connected to a frontal end of the injection pipe, wherein the injection pipe comprises a flexible 1st pipe section constituting a frontal side of the injection pipe, and a 2nd pipe section being more rigid than the 1st pipe section and constituting a rear side of the injection pipe.
