Compact Pipe Connector with Integrated Fixing Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connectors have a complex structure with a large overall height, making them difficult to assemble and install, especially in hard-to-reach locations, due to their dual connection types and additional components like union nuts.
Innovation Solution
A pipe connector design where the fixing part can be slid over the support body, eliminating the need for a separate union nut, with a claw element connected to the clamping element to securely hold the pipe end, and made from high-performance plastics for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pipe connector uses a separate union nut and clamping arrangement for threaded engagement, then secure connection is achieved, but the overall height and structural complexity increase
Solution Approach 1:
The patent combines the union nut and clamping arrangement into a single integrated fixing part made of plastic. This fixing part simultaneously provides threaded engagement with the pipe connection and houses the clamping mechanism for the pipeline end, eliminating the need for separate components and reducing overall height while maintaining connection security
Solution Approach 2:
The fixing part serves multiple functions: it provides threaded engagement with the pipe connection, houses the clamping mechanism for securing the pipeline end, and integrates the seal assembly. This multi-functional design reduces the number of components needed and simplifies the overall structure
2Adaptability or versatility
If a pipe connector uses multiple separate components for dual connection types, then connection versatility is achieved, but assembly difficulty increases in hard-to-reach locations
Solution Approach 1:
The fixing part integrates both the threaded connection interface and the plug connector clamping mechanism into a single component. This allows the pipe connector to provide both connection types (threaded and push-fit) while requiring fewer separate components to be assembled, making installation easier in hard-to-reach locations
3Reliability
If a pipe connector uses a separate union nut and clamping element, then reliable pipe end clamping is achieved, but device complexity increases
Solution Approach 1:
The fixing part integrates the clamping mechanism directly into its structure, with the clamping element positioned within the fixing part itself. This eliminates the need for a separate union nut while maintaining reliable pipe end clamping through the integrated clamping arrangement

AI summary
The pipe connector has a supporting portion (6) that is provided at secondary terminal end. A fixing portion (7) is provided for fixing pipe end. A clamping element (8) is radially arranged between fixing portion and the supporting portion. The clamping element is moved relative to the fixing portion in clamping direction. The wall portion of the clamping element is pressed against the outer side of the pipe end such that the end portion (15) of fixing portion is connected with primary terminal end by screw element (14).
