Solution Overview
Problem
Existing pipe fittings for expansion tanks are not easily adaptable to different types of ducts, leading to inefficient production processes that depend on the specific hydraulic system and connection type.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pipe fitting is made as a single integrated component with a fixed shape, then the manufacturing process is simple, but the adaptability to different duct types is poor
Solution Approach 1:
The pipe fitting is divided into two separate components: a coupling body (first component) and an adapter body (second component). The coupling body remains fixed in the expansion tank, while the adapter body can be removed and replaced with different types depending on the duct connection requirements. This segmentation allows the system to maintain a simple base structure while achieving versatility through component interchangeability.
Solution Approach 2:
The coupling body serves as a universal base component that can work with multiple types of adapter bodies. The standardized interface between the coupling body and various adapter bodies allows a single coupling body design to support multiple duct connection types (threaded, flanged, welded, etc.), achieving multi-functionality without increasing the complexity of the base component.
2Ease of manufacture
If the pipe fitting is customized for each specific hydraulic system type, then the connection compatibility is perfect, but the production process becomes inefficient and costly
Solution Approach 1:
By separating the pipe fitting into a standard coupling body and customizable adapter bodies, the manufacturing process can be optimized. The coupling body can be produced in large quantities as a standard component, while only the adapter bodies need to be customized for specific applications. This reduces production complexity compared to creating entirely custom fittings for each application.
Solution Approach 2:
The coupling body is designed and manufactured in advance as a universal base component with standardized dimensions and connection interfaces. This preliminary action allows the expansion tank production to proceed efficiently without waiting for custom fitting designs, while adapter bodies can be added later to match specific duct requirements.
3Adaptability or versatility
If the pipe fitting uses multiple separate components, then the adaptability to different connection types is improved, but the device complexity increases
Solution Approach 1:
The pipe fitting is segmented into exactly two components (coupling body and adapter body) - no more, no less. This minimal segmentation achieves the necessary adaptability while keeping the number of components low. The coupling body provides the fixed connection to the expansion tank, and the adapter body provides the variable connection to different duct types.
Solution Approach 2:
The coupling body and adapter body are designed to combine into a unified assembly that functions as a complete pipe fitting. The interface between the two components is designed to be simple and direct, allowing them to work together as an integrated system while maintaining the flexibility of separate components.
