Pipe Connection Sleeve With Seal Protection and Insertion Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for pipes lack effective protection for the sealing device, leading to potential damage from burrs and improper insertion angles, which can result in tilting and uneven sealing.
Innovation Solution
A connection system featuring a sliding device with a protective and display function, where the protective device and display device are positioned in the same direction but not equally, providing enhanced resistance and stability, and incorporating an elastic buffer element or compensation element to manage insertion angles and prevent tilting, along with a clamping device for centering and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective sleeve is provided to cover the sealing device, then the sealing device is protected from burrs, but the protective sleeve is pushed off the sealing device before the pipe engages, failing to fulfill its protective function
Solution Approach 1:
The sliding device is pre-positioned in the receiving chamber to cover the sealing device before pipe insertion begins. The device is designed to maintain its protective position throughout the insertion process, preventing burrs from contacting the sealing device while allowing proper pipe engagement.
Solution Approach 2:
The sliding device acts as an intermediary protective barrier between the pipe end and the sealing device. It is designed to interact with the pipe during insertion, maintaining its protective function while allowing the pipe to engage properly with the connection assembly.
2Ease of operation
If the pipe is not properly deburred after cutting, then insertion is easier, but the sealing device is damaged by burrs during insertion
Solution Approach 1:
The sliding device is positioned in advance to prevent the harmful effect of burrs from reaching the sealing device. By creating a physical barrier before insertion occurs, the system protects the sealing device without requiring perfect pipe preparation, thus maintaining ease of operation while ensuring reliability.
3Productivity
If the pipe is inserted at an angle, then insertion speed increases, but the sliding device tilts and the sealing unit is pushed out unevenly
Solution Approach 1:
An elastic buffer element is provided at the end of the sliding device facing the pipe. This buffer element absorbs and distributes forces from angled insertion, preventing the sliding device from tilting and ensuring the sealing unit remains evenly positioned. The cushioning effect maintains stability even when pipes are inserted at angles, allowing faster insertion without compromising alignment.
4Force
If the protective device and indicator device are connected operationally in a one-piece design, then the mass increases providing more resistance, but the device complexity increases
Solution Approach 1:
The protective device (sliding device) and indicator device are merged into a single operational unit. The sliding device incorporates both the protective sealing function and the indication function, with the indicator ring integrated into the sliding device structure. This merging increases the overall mass for better resistance during insertion while the integrated design actually reduces complexity compared to separate components.
