Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional water pipe connection device is used to interconnect two water pipes, then the water pipes can be connected together, but additional tools are required for installation which makes the process more troublesome
Solution Approach 1:
The water pipe connection device enables self-service installation through its integrated design. The bell-shaped tube head with tapered structure allows the water pipe to be inserted and fixed automatically without external tools. The fastening member and fixing unit work together to secure the connection through the insertion force alone, eliminating the need for additional installation tools and simplifying the installation process.
2Reliability
If a conventional water pipe connection device is used to connect water pipes, then the pipes can be joined, but the device may come loose and separate from the water pipe due to excessive water pressure
Solution Approach 1:
The device applies preliminary anti-action by pre-positioning the fastening member and fixing unit in a configuration that anticipates water pressure forces. The tapered bell-shaped structure and the interlocking mechanism between the fastening member and fixing unit create a preliminary constraint that counteracts the separating force of water pressure before it can cause loosening or separation.
Solution Approach 2:
The device incorporates dynamic elements that allow it to adapt to water pressure conditions. The fastening member and fixing unit are designed with movable components that can adjust their positioning in response to water pressure, maintaining optimal clamping force dynamically rather than relying on a fixed rigid structure.
3Reliability
If additional tools are used for hot-pressing or ring fixation in conventional connection devices, then secure connection can be achieved, but the installation process becomes more troublesome and complex
Solution Approach 1:
The invention merges multiple functions into a single integrated connection device. The bell-shaped tube head, fastening member, and fixing unit are combined into one device that performs both connection and securing functions simultaneously. This eliminates the need for separate hot-pressing equipment or additional rings, reducing installation complexity while maintaining connection security.
Solution Approach 2:
The connection device exhibits multi-functionality by combining the roles of the bell-shaped coupling, fastening mechanism, and fixing unit into a single universal device. This unified structure can accommodate water pipes of appropriate sizes and provides both mechanical connection and pressure-resistant securing capabilities without requiring multiple specialized tools or components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device securely connects water pipes without additional tools and maintains the connection even under high water pressure by using the fastening member and fixing unit to clamp and seal the pipe effectively.
Implementation Method 1
water flows into the installation space through a space between the tubular member and the water pipe, and the fastening member is pushed by the water to move the fixing unit towards the small tubular section
Implementation Method 2
The water pipe is clamped and positioned by the teeth portions of the reverse toothed structures

AI summary
A water pipe connection device includes a connecting tube (1), a fastening member (2), and a fixing unit (4). The connecting tube (1) includes a tapering tube head (11) and a tubular member (12). The fastening member (2) is disposed in the tube head (11). The fixing unit (4) is disposed in the tube head (11), and includes a fixing ring (41) and a plurality of reverse toothed structures (42). A water pipe (9) is clamped and positioned by teeth portions of the reverse toothed structures (42). When the water pipe connection device is in use, water flows into the tube head (11) through a space between the tubular member (12) and the water pipe (9), and the fastening member (2) is pushed by the water to move the fixing unit (4) towards a tapered end of the tube head (11), so that the fixing unit (4) is pressed by the tube head (11) to fix the water pipe (9).
