Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick pipe couplings are not convenient to use and do not allow for immediate visualization of the installation state, leading to potential water leakage issues during pipe installation.
Innovation Solution
A new quick pipe coupling design featuring a hollow tubular joint body with a spiral interface, a transparent lower outer shell, and interlocking inner and outer ring gears with oblique anti-skid teeth, along with a movable cavity and visual ring for visual confirmation of proper pipe insertion, ensuring a self-locking and leak-proof connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional quick pipe coupling is used, then quick installation is achieved, but the installation state cannot be visually confirmed and water leakage risks remain hidden
Solution Approach 1:
The patent uses a transparent lower outer shell to enable visual confirmation of the installation state. This allows operators to directly observe whether the pipe is properly inserted and locked without disassembling or guessing, transforming the hidden installation state into visible information and eliminating the risk of undetected water leakage.
2Productivity
If a simple quick coupling structure is used, then installation speed is improved, but the locking mechanism may not be reliable under water pressure
Solution Approach 1:
The patent employs a dynamic self-locking mechanism where the inner ring gear and outer ring gear interact through oblique anti-skid teeth. When water pressure acts on the pipe, it automatically drives the ring gears to engage the anti-skid teeth, creating a self-locking effect that prevents the pipe from moving or leaking, thereby enhancing reliability without compromising installation speed.
Solution Approach 2:
The quick pipe coupling utilizes the water pressure itself as the locking force. The oblique anti-skid teeth on the inner and outer ring gears are designed to engage automatically when pressure is applied, making the system self-locking without requiring additional components or manual adjustment, thus maintaining quick installation while ensuring reliable locking under pressure.
3Loss of information
If a transparent outer shell is used for visual confirmation, then installation state visibility is improved, but the structural strength may be reduced
Solution Approach 1:
The patent divides the outer shell into an upper outer shell and a lower outer shell that are spliced together. The lower outer shell is made transparent for visual confirmation, while the upper outer shell can be made of stronger opaque material. This segmentation allows different parts of the shell to serve different functions - transparency for observation and material strength for structural support - thereby resolving the contradiction between visibility and strength.

AI summary
The present invention discloses a new quick pipe coupling, which includes a joint body, an inner ring gear, an inner ring gear bushing, an outer ring gear, an outer shell and a visible ring. The upper part of the joint body is provided with sealing ring grooves, the middle part of the joint body is provided with an inner ring gear groove, the lower part of the joint body is provided with a spiral interface. The inner ring gear is sleeved inside the inner ring gear groove, and the bottom of the inner ring gear is provided with an inner ring gear bushing. The outer ring gear is fixed on the inner side wall of the outer shell, and the lower part of the outer ring gear is provided with a visible hole. A cavity between the inner ring gear and the outer ring gear is a movable cavity, and the visible ring is movably arranged inside the movable cavity. The present invention belongs to a self-locking structure and adopts the form of double locking inside and outside the pipe. The larger the water pressure is, the more tightly the pipe locks. Construction personnel can quickly install the pipe without using tools, and can visually check whether the pipe is installed properly through the visual hole and visual ring, thus improving the installation qualification rate of the pipe, saving time and labor and improving the working efficiency, which will be a new innovative technology for connection and installation.
