Elastic Bushing Fluid Connector for High-Pressure Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid connectors struggle to maintain a secure connection with main pipes under high-pressure conditions due to expansion in the circumferential and longitudinal directions, leading to separation or gaps that cause water leakage.
Innovation Solution
A fluid connector design featuring a socket, elastic bushing, washer, and tightening nut that pressurize inner and outer corners of the coupling hole in multiple directions, including the longitudinal and circumferential directions, using elastic deformation to maintain a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the socket head is pressurized only in the thickness direction to connect to the main pipe, then the connection is simple to implement, but the connector cannot hold the expanding main pipe under high-pressure water conditions
Solution Approach 1:
The elastic bushing is designed to pressurize the main pipe not only in the thickness direction but also in the longitudinal and circumferential directions. This multi-directional pressurization approach adds dimensional complexity to the connection mechanism, enabling the connector to reliably hold the expanding main pipe under high-pressure water conditions while maintaining ease of installation.
2Reliability
If the socket head is pressurized in multiple directions to hold the main pipe, then the connection stability under pressure is improved, but the structure becomes more complex
Solution Approach 1:
The elastic bushing is made of flexible elastic material that can deform and pressurize the main pipe in multiple directions (thickness, longitudinal, and circumferential directions). This flexible component achieves multi-directional holding force without requiring a complex multi-component structure, thus improving connection stability while controlling structural complexity.
3Reliability
If the elastic bushing pressurizes the main pipe in longitudinal and circumferential directions, then the connector prevents separation and leakage, but the installation process becomes more complex
Solution Approach 1:
The elastic bushing is designed to automatically deform and pressurize the main pipe in multiple directions upon installation. The elastic material self-adjusts to the pipe's expansion under pressure, maintaining seal integrity without requiring complex installation procedures or additional adjustment steps, thus achieving reliable sealing while keeping installation relatively simple.
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 design effectively prevents separation and leakage by firmly securing the connector to the main pipe, minimizing deformation and ensuring a tight seal under high-pressure conditions.
Implementation Method 1
the elastic bushing is provided to pressurize each of an inner corner, positioned at a lower end of an inner peripheral surface of the coupling hole, and an outer corner, positioned at an upper end thereof, in a height direction of the main pipe and, at the same time, in at least one direction of a longitudinal direction and circumferential direction of the main pipe while being elastically deformed by pressure delivered through the socket and the washer

AI summary
Provided is a fluid connector, the fluid connector being coupled to a coupling hole formed by perforating a main pipe, wherein the fluid connector includes: a socket, at least a portion of which is inserted into the coupling hole; an elastic bushing movably mounted on the socket such that at least a portion of the elastic bushing is inserted into the coupling hole together with the socket; a washer movably mounted on the socket to be disposed outside the main pipe in a state of facing the elastic bushing; and a tightening nut screw-coupled to the socket to be disposed outside the main pipe in a state of facing the washer.
