Push-Fit Conduit Joint Release Structure With Multilayer Gear Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-fit conduit connection technologies suffer from issues of excessive fittings, poor structural stability, and insufficient clamping due to the single-layer structure of the gear ring, which complicates installation and removal processes.
Innovation Solution
A multilayered gear ring design with a first notch and limit ring groove, combined with a propeller and sleeve structure, allows for improved clamping and structural stability, enabling easy installation and removal of conduits without additional support components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer gear ring structure is used, then the device complexity is reduced, but the clamping force and structural stability are insufficient
Solution Approach 1:
The patent transitions from a single-layer gear ring to a multi-layer gear ring structure, adding the dimensional aspect of layering. This multi-layer configuration increases the clamping force and structural stability without significantly increasing device complexity, as the layers are integrated within the same component framework.
Solution Approach 2:
The gear ring employs a composite structure with teeth made of different material hardness than the body. The teeth are made of harder material to increase clamping force on the conduit, while the body provides structural support. This material composite approach resolves the contradiction between complexity and strength.
2Stability of the object's composition
If additional seal ring support components and pipeline support components are added, then the structural stability is improved, but the quantity of fittings increases
Solution Approach 1:
The patent merges the functions of seal ring support and pipeline support into the gear ring structure itself. The limit ring groove in the main body and the gear ring's integrated design eliminate the need for separate support components, reducing the number of fittings while maintaining structural stability.
Solution Approach 2:
The gear ring is designed to perform multiple functions: clamping the conduit, providing structural support, and stabilizing the seal ring. This multi-functional design replaces multiple specialized components with a single versatile element, reducing fitting quantity while improving stability.
3Ease of manufacture
If the gear ring is made with a single-layer structure, then the manufacturing process is simplified, but the clamping reliability is insufficient
Solution Approach 1:
The gear ring is segmented into distinct functional zones: the body portion and the teeth portion with different material properties. This segmentation allows each zone to be optimized for its specific function while maintaining a relatively simple integrated manufacturing process, achieving both ease of manufacture and clamping reliability.

AI summary
A push type conduit joint release structure is provided, and relates to the field of conduits. The push type conduit joint release structure includes a tubular main body. The main body is internally provided with a gear ring and a propeller. The gear ring includes an outer ring with a first notch, and a plurality of teeth slantly protrude towards an axial direction of the outer ring on an inner wall of the outer ring. An inner circumferential wall of the main body is concave at the position of the gear ring to form a limit ring groove. When the gear ring is located inside the limit ring groove, the teeth protrude out of an inner circumferential wall of the propeller.
