One-Touch Pipe Coupling With Integrated Cap-Pressed Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection methods require manual insertion and removal of rubber rings and fastening members for each connection and disconnection, leading to inefficiencies, increased labor, and potential for part loss and leakage.
Innovation Solution
A one-touch pipe connection device featuring a socket main body with pipe fitting portions, a sealing member with an oval section and elastically deformable ring shape, and a cap portion with a pressure guide portion that induces flexural deformation of the sealing member for secure sealing without manual separation of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner diameter of the rubber ring is made smaller than the outer diameter of the pipe to increase sealing force, then sealing performance is improved, but manual insertion and removal of the rubber ring is required at every connection and disconnection
Solution Approach 1:
The sealing ring is nested within the cap portion, which itself is nested within the pipe fitting portion. This nested structure allows the sealing ring to be pre-positioned and protected, eliminating the need for manual insertion and removal while maintaining its sealing function through the cap's pressing action.
Solution Approach 2:
The sealing ring is pre-installed within the cap portion before the actual pipe connection is made. The cap portion is designed with a pressing ring that pre-compresses the sealing ring against the pipe, ensuring sealing is established automatically when the cap is coupled to the pipe fitting portion, without requiring manual intervention at connection time.
2Adaptability or versatility
If fastening members and sealing rings are completely separated from the pipe coupling for each connection and disconnection, then the pipe can be reconnected, but additional manual work and potential part loss occur
Solution Approach 1:
The cap portion integrates both the fastening function (through its coupling mechanism with the pipe fitting portion) and the sealing function (through the integrated pressing ring and sealing ring). This merged structure eliminates the need to handle separate fastening members and sealing rings, reducing manual work and preventing part loss while maintaining reconnection capability.
Solution Approach 2:
The cap portion serves multiple functions simultaneously: it acts as a fastening member to secure the pipe, provides sealing through the pressing ring and sealing ring, and enables easy disconnection and reconnection. This multi-functional design eliminates the need for separate components and manual operations for each function.
3Reliability
If multiple separate components (fastening member, rubber ring, pipe coupling) are used for pipe connection, then connection reliability is improved, but device complexity and manual operation difficulty increase
Solution Approach 1:
The invention merges the cap portion, pressing ring, and sealing ring into an integrated assembly that couples with the pipe fitting portion as a single unit. This reduces the number of separate components that need to be handled and assembled, simplifying the overall device structure while maintaining connection reliability through the integrated sealing and fastening mechanisms.
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
Facilitates quick and easy pipe connection and disconnection by releasing the cap portion only, reducing labor and preventing part loss, while enhancing sealing performance through dual sealing positions.
Implementation Method 1
a sealing member (120) with an oval section in which a major axis is formed in the insertion direction (I) of the pipe (10) to be connected
Implementation Method 2
a cap portion (130) with a through hole (132) formed therein to pass the pipe (10) to be connected inserted in the pipe fitting portion (111), coupled to the pipe fitting portion (111) while moving in an insertion direction (I) of the pipe (10) to be connected inserted in the pipe fitting portion (111), and, when coupled to the pipe fitting portion (111), pressing the sealing portion in a direction in which the sealing portion closely contacts the pipe (10) to be connected
