Detachable Sprinkler Pipe Coupling for Leak-Free Branch Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinkler systems require welding to connect inlet and branch pipes, leading to potential fluid leaks, increased assembly time, and higher construction costs, with further issues when the branch hole diameter is increased to enhance fluid flow.
Innovation Solution
A sprinkler system utilizing detachable couplers to connect pipes without welding, featuring locking protrusions and gaskets to prevent leaks, and a second coupler design that increases gasket pressure with distance to effectively manage increased branch hole diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect inlet pipe and branch pipe, then connection strength is improved, but reliability deteriorates due to faulty welding causing fluid leaks
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a mechanical coupling system consisting of a coupling body, locking protrusions, and locking grooves. This mechanical connection method eliminates the reliability issues associated with welding while maintaining connection strength through the interlocking mechanism and sealing elements.
Solution Approach 2:
The coupling body serves as an intermediary component that connects the inlet pipe and branch pipe without direct welding. The coupling body includes sealing surfaces and locking mechanisms that mediate the connection between pipes, preventing fluid leaks while maintaining structural integrity.
2Duration of action of stationary object
If welding is used to connect pipes, then connection durability is improved, but ease of repair deteriorates due to difficulty in maintenance operations
Solution Approach 1:
The patent segments the pipe connection system into separate, detachable components: inlet pipe, coupling body, and branch pipe. This segmentation allows the branch pipe to be easily disconnected and removed for maintenance without affecting the main inlet pipe, significantly improving ease of repair while maintaining connection durability through the robust coupling mechanism.
3Productivity
If branch hole diameter is increased to increase fluid flow rate, then productivity is improved, but reliability deteriorates due to fluid leakage
Solution Approach 1:
The patent employs a flexible sealing structure within the coupling body that includes a sealing surface and locking mechanism. This sealing structure adapts to the branch hole diameter and maintains effective sealing even when the diameter is increased to improve fluid flow rate, preventing leakage while maintaining productivity.
