Quick Pipe Connector with Visual Insertion Leak Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick pipe connectors do not provide a visual indication of secure pipe connection, leading to potential leakage issues.
Innovation Solution
A quick pipe connector with a visualized insertion arrangement featuring a transparent sleeve and windows allows users to visually confirm proper pipe insertion, ensuring secure connection and preventing leakage through sealing rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional quick pipe connector is used, then the connection structure is simple, but the user cannot visually confirm proper pipe insertion leading to potential leaks
Solution Approach 1:
A transparent visual indicator sleeve is introduced as an intermediary component between the pipe insertion area and the user's observation point. This sleeve allows visual confirmation of proper pipe insertion without requiring the user to directly observe internal connection mechanisms, thus improving reliability while adding minimal structural complexity.
Solution Approach 2:
The visual indicator sleeve utilizes color changes or transparency variations to indicate connection status. When the pipe is properly inserted, the sleeve displays a specific visual state (e.g., becomes transparent or changes color), providing immediate feedback to the user without complex mechanical indicators.
2Reliability
If sealing rings are added to prevent leaks, then connection reliability improves, but device complexity increases
Solution Approach 1:
The sealing ring is designed to automatically engage and seal when the pipe is inserted into the connector. The insertion action itself activates the sealing mechanism without requiring additional manual steps or complex actuation systems, thus improving leak prevention while minimizing increases in device complexity.
Solution Approach 2:
The sealing ring is pre-positioned and pre-configured within the connector body before pipe insertion. This preliminary arrangement ensures that sealing is immediately effective upon insertion, eliminating the need for additional sealing actions or complex multi-stage sealing mechanisms.

AI summary
A quick pipe connector includes a connector body, an inner sealing ring, an outer sealing ring, a biasing ring sandwiched between the inner sealing ring and the outer sealing ring, a securing ring attached to a connecting portion of the connector body, an engaging member arranged to bias against the securing ring and includes a plurality of catching claws, and a coupling sleeve. The coupling sleeve includes a main sleeve member having a through hole, and an extension sleeve extending from the main sleeve member to engage with the connecting portion of the connector body. When the pipe is inserted in the connector body, the inner sealing ring, the outer sealing ring, the biasing ring, the securing ring and the engaging member are securely biased and retained between the connector body and the main sleeve member.
