Detachable Pipe Stopper Plug for Unobstructed High-Pressure Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline repair methods require the insertion line to remain connected to the plug during and after repairs, limiting accessibility and efficiency in the repair process.
Innovation Solution
An inflatable or compressible plug system with a detachable and reconnectable inflation/insertion line, utilizing a magnetic coupling for easy connection and disconnection, allowing the line to be detached during repairs and reconnected for plug removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the insertion line remains connected to the plug during repairs, then the plug can maintain its sealing function, but the repair process is obstructed and accessibility is limited
Solution Approach 1:
The system is divided into separable components: the plug with sealing elements and the insertion line with coupling mechanisms. The quick-connect/coupling allows these segments to be detached from each other, enabling the line to be removed for unobstructed repair access while the plug remains in place maintaining the seal.
Solution Approach 2:
The quick-connect coupling acts as an intermediary mechanism that facilitates easy connection and disconnection between the insertion line and the plug. This intermediary allows the system to transition between connected and detached states without compromising the sealing function when connected or the accessibility when detached.
2Ease of operation
If the insertion line is detached from the plug during repairs, then accessibility is improved, but the plug cannot be easily retrieved after repair
Solution Approach 1:
The quick-connect coupling mechanisms are pre-configured on both the plug and insertion line before the repair process begins. This preliminary setup ensures that when retrieval is needed, the connection can be quickly re-established without time-consuming alignment or complex coupling procedures.
Solution Approach 2:
The traditional complex mechanical coupling systems are replaced with simpler quick-connect mechanisms that use features such as magnetic attraction, spring-loaded latches, or bayonet-style connectors. These substituted mechanisms dramatically reduce the time and effort required for reconnection during the retrieval phase.
3Productivity
If a traditional stopping device is used, then the pipeline can be sealed, but the device complexity increases and efficiency is reduced
Solution Approach 1:
The inflation/insertion line is extracted as a separate, removable component from the plug assembly. This extraction allows the plug to function independently as a simple sealing device while the line serves as a temporary delivery and control mechanism that can be completely removed, reducing overall system complexity during the repair phase.
Solution Approach 2:
The insertion line is designed to be temporarily used (discarded after use) for installing and inflating the plug, then completely removed from the system. The plug itself is recovered and retained in the pipeline for the duration of the repair, while the complex line infrastructure is discarded, simplifying the overall system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and safe temporary or permanent sealing of pipelines for repairs, allowing for unobstructed access and easy retrieval of the plug after repairs are completed, improving the overall repair process.
Implementation Method 1
The coupling may further include a magnet for simplifying the connection of the line to the plug

AI summary
A system for stopping flow in a pipe with a plug positioned in the pipe to allow for repairs of the pipe. The plug comprises a body with an inflatable or compressible member, and a cap and connector valve on the body. An inflation line with a coupling connects to the valve for blocking off and sealing a damaged area of the pipe. An inflation line is used to deposit and retrieve the plug within the pipe before and after a repair is made.
