Water Pipe Connector With Pressure-Activated Reverse-Tooth Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water pipe connection devices require additional tools for installation and can become loose under excessive water pressure, leading to separation of the water pipes.
Innovation Solution
A water pipe connection device featuring a connecting tube with a tubular member, a fastening member, and a fixing unit with reverse toothed structures that secure the water pipe using water pressure to prevent separation, eliminating the need for additional tools and ensuring stability under high pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional tools are used for hot-pressing or ring fixation, then the water pipe can be securely attached to the connection device, but the installation process becomes more troublesome and complex
Solution Approach 1:
The water pressure from the flowing water automatically pushes the fastening member to move the fixing unit, causing the teeth portions to clamp and position the water pipe securely without requiring any additional tools or manual intervention for fixation
Solution Approach 2:
The patent utilizes the hydraulic pressure of flowing water as the driving force to move the fastening member and fixing unit, converting the water pressure into mechanical motion that automatically secures the water pipe to the connection device
2Device complexity
If conventional connection devices are used without self-fixing mechanisms, then the structure remains simple, but the device may come loose and separate from the water pipe due to excessive water pressure
Solution Approach 1:
The fixing unit is designed to be movable rather than fixed, allowing it to respond dynamically to water pressure by automatically adjusting its position to clamp and secure the water pipe, ensuring the device remains stable under varying pressure conditions
Solution Approach 2:
The fastening member and fixing unit automatically activate in response to water pressure, with the flowing water itself providing the force needed to secure the connection, eliminating the need for complex external fixation mechanisms
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 allows for tool-free installation and secure attachment of water pipes, maintaining connection integrity even under high water pressure without the need for hot pressing or rings.
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

AI summary
A water pipe connection device includes a connecting tube, a fastening member, and a fixing unit. The connecting tube includes a tapering tube head and a tubular member. The fastening member is disposed in the tube head. The fixing unit is disposed in the tube head, and includes a fixing ring and a plurality of reverse toothed structures. A water pipe is clamped and positioned by teeth portions of the reverse toothed structures. When the water pipe connection device is in use, water flows into the tube head 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 a tapered end of the tube head, so that the fixing unit is pressed by the tube head to fix the water pipe.
