Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hot water distribution pipes for boilers are complex and costly to construct due to the need for threaded connections, which complicate the coupling of branch pipes and make it difficult to achieve airtight connections, especially at limited rotation angles.
Innovation Solution
A manifold type pipe structure featuring a joint coupler with a connection valve and finishing coupler that allows for easy coupling of branch pipes at limited rotation angles using engaging protrusions and a pressurizing mechanism, enabling airtight connections without the need for conventional threading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections are used for coupling branch pipes, then airtight connections can be achieved, but the structure becomes complicated and construction work becomes difficult
Solution Approach 1:
The coupling system is divided into separate components: a coupling body with internal threading and separate coupling nuts. This segmentation allows the complex threaded connection function to be isolated to specific parts rather than requiring complex threading on all surfaces, simplifying the overall structure while maintaining airtight connection capability.
Solution Approach 2:
A sealing member (gasket or O-ring) is introduced as an intermediary element between the coupling body and the branch pipes. This intermediary provides the airtight seal function, allowing the main coupling structure to be simpler without threaded connections on all surfaces, thus reducing structural complexity while ensuring reliability.
2Reliability
If multiple nuts are coupled after sealing member engagement, then airtight connections are ensured, but construction costs increase
Solution Approach 1:
Multiple coupling nuts are merged into a single integrated coupling body with multiple internal threading locations. This consolidation reduces the total number of separate parts (fewer nuts to purchase and install), simplifying the bill of materials and reducing construction costs while maintaining the airtight connection function through internal sealing mechanisms.
3Adaptability or versatility
If branch pipes are coupled at limited rotation angles, then installation flexibility is improved, but achieving airtight connections becomes difficult
Solution Approach 1:
The coupling body incorporates a rotating joint mechanism that allows dynamic adjustment of the branch pipe angle during installation. This dynamic capability enables coupling at various rotation angles while maintaining proper sealing surface alignment, thus providing installation flexibility without compromising airtight connection reliability.
Solution Approach 2:
The coupling system allows change in the angular parameter of the branch pipe connection. By designing the coupling body with adjustable orientation and flexible sealing mechanisms, the system can adapt to different rotation angles while maintaining effective sealing, thus improving adaptability without sacrificing connection reliability.
