Telescopic Pipe Connector With Anti-Detachment Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection devices face issues with unreliable connections due to length mismatches and unpredictable insertion depths, leading to potential detachment under pressure, especially when connecting symmetrical pipes.
Innovation Solution
A pipe connection device comprising an inner connection pipe with a detachment preventing groove and an outer connection pipe with a detachment preventing protrusion, which are designed to catch and fix each other, limiting insertion depth and preventing separation, while using sliding mechanisms to adjust length and secure the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the connector is made relatively longer to connect symmetrical pipes, then the connection length is increased, but the connector cannot be placed between the pipes and accurate insertion depth prediction becomes impossible
Solution Approach 1:
The connector is divided into two separate pipes: an inner connection pipe and an outer connection pipe. The inner pipe has a first inserting portion that fits into the first pipe, while the outer pipe has a second inserting portion that fits into the second pipe. This segmentation allows each pipe to be independently sized and inserted to the correct depth, solving the problem of controlling insertion depth while maintaining adequate connection length.
2Length of moving object
If the connector is made relatively longer, then the connection coverage is improved, but the connector becomes easily detached due to water pressure
Solution Approach 1:
The inner connection pipe is nested within the outer connection pipe, forming a telescopic structure. The inner pipe extends from the first pipe toward the second pipe, and the outer pipe extends from the second pipe toward the first pipe, with both pipes overlapping in the middle section. This nesting arrangement distributes the mechanical stress from water pressure across multiple connection points and allows the structure to flex without detaching, improving reliability while maintaining adequate connection length.
3Length of moving object
If the connector is made relatively longer, then the pipe connection capability is improved, but the device complexity increases
Solution Approach 1:
The connector is divided into two separate pipes: an inner connection pipe and an outer connection pipe. The inner pipe has a first inserting portion that fits into the first pipe, while the outer pipe has a second inserting portion that fits into the second pipe. This segmentation allows each pipe to be independently sized and inserted to the correct depth, solving the problem of controlling insertion depth while maintaining adequate connection length.
4Length of moving object
If the connector is made relatively longer, then the connection adaptability is improved, but the ease of installation deteriorates
Solution Approach 1:
The inner and outer connection pipes are designed to slide relative to each other along their common longitudinal axis during installation. The inner pipe can be inserted first, followed by the outer pipe that slides over it, or vice versa. This dynamic telescopic capability allows the connector to be easily installed and adjusted to fit various pipe configurations without requiring complex alignment procedures.

AI summary
Disclosed is a pipe connection device for repairs that connects first and second pipes by extending a length of inner and outer connection pipes, wherein the first and second pipes are connected using the inner and outer connection pipes in a state in which the inner and outer connection pipes are fixed while extended to be proportional to a length between the first and second pipes by a detachment preventing protrusion being caught in and fixed to a detachment preventing groove while an inner catching step is caught on an outer catching step to limit sliding.
