Grooved Joint Adapter for Pipe Connection Without Pre-Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grooved joint technologies require pre-forming grooves in pipes, which increases construction costs, complexity, and reduces productivity due to the need for specialized equipment and skilled labor, and limits the ability to connect pipes of different materials without matching diameters.
Innovation Solution
A grooved joint adapter that connects pipes without pre-forming grooves, using a cylindrical body with an insertion port and a groove, guide portion, coupling portions, a pressure ring, stopper ring, and rubber ring to securely join pipes of various shapes and materials, including linear, T-shaped, and curved pipes, through bolt-coupling and wedge sawteeth, allowing for easy assembly and leak prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grooves are formed in pipe ends using a grooving machine, then pipes can be connected via grooved joint, but construction costs increase and productivity decreases
Solution Approach 1:
The invention extracts the groove-forming operation from the pipe connection process. Instead of forming grooves in pipe ends at the construction site, the grooves are pre-formed during pipe manufacturing, and the adapter simply receives the pipes with pre-formed grooves, eliminating the need for on-site grooving machines and skilled operators.
Solution Approach 2:
The grooves are prepared in advance during pipe manufacturing rather than at the construction site. This preliminary action transfers the groove-forming process to the factory setting, where it can be performed efficiently with standardized equipment, improving on-site construction productivity.
2Reliability
If grooves are formed in pipe ends using a grooving machine, then pipes can be connected via grooved joint, but construction costs increase
Solution Approach 1:
The invention extracts the groove-forming operation from the construction process and transfers it to pipe manufacturing. This eliminates the need for expensive on-site grooving equipment and skilled operators, thereby reducing construction costs while maintaining connection reliability through the adapter design.
3Reliability
If grooves are formed in pipe ends, then pipes can be connected, but the process requires expert workmanship which is difficult to perform
Solution Approach 1:
The invention removes the complex groove-forming operation from the on-site connection process. The adapter is designed to receive pipes with pre-formed grooves, allowing workers to simply attach the adapter without requiring expert skills in groove formation, thereby improving ease of operation.
Solution Approach 2:
The groove formation is performed in advance during pipe manufacturing, converting a difficult on-site operation into a standardized factory process. This allows on-site workers to focus on the simple task of attaching the adapter, significantly improving ease of operation.
4Reliability
If grooves are pre-formed in pipes, then connection can be made, but formability and productivity are reduced
Solution Approach 1:
The invention extracts the groove-forming process from the construction site operation and relocates it to pipe manufacturing. This separation allows factory-based mass production of grooved pipes, improving overall productivity while maintaining connection reliability through the adapter design.
