Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe joining methods are prone to rupture due to vibrations caused by fluid flow, as they do not allow for movement between the pipes, and often require extensive welding or gluing, which complicates installation and reuse.
Innovation Solution
A pipe joining apparatus featuring a snap-fit fastener with interlocking semi-circular portions that enables relative movement between couplers, reducing the need for extensive welding or gluing and allowing for vibration absorption, while incorporating sealing rings to prevent fluid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If pipes are joined by welding or gluing with rigid clamps or collars, then the join strength is improved, but the ability to absorb vibrations is worsened
Solution Approach 1:
The coupling device incorporates a resilient element that allows dynamic movement between the first and second couplers, enabling the joint to absorb vibrations from fluid flow while maintaining secure connections. This dynamic capability resolves the contradiction by allowing movement without compromising joint integrity.
Solution Approach 2:
The invention changes the physical state of the connection from rigid to flexible by introducing a resilient element. This parameter change allows the joint to maintain strength while gaining vibration absorption capability, effectively resolving the contradiction between join strength and vibration resistance.
2Reliability
If extensive welding or gluing is used to secure pipe joints, then the connection reliability is improved, but the installation complexity and time are worsened
Solution Approach 1:
The coupling device is segmented into separate components (first coupler, second coupler, and resilient element) that can be independently assembled. This segmentation eliminates the need for extensive welding or gluing operations, significantly reducing installation time while maintaining connection reliability through the snap-fit mechanism.
Solution Approach 2:
The invention replaces thermal joining methods (welding and gluing) with a mechanical snap-fit system. This substitution maintains connection reliability through the interlocking coupler design while dramatically reducing installation time and complexity.
3Stability of the object's composition
If rigid clamps or collars are used to join pipes, then the structural stability is improved, but the reusability is worsened
Solution Approach 1:
The resilient element provides structural stability through controlled flexibility, allowing the joint to maintain its composition while enabling easy assembly and disassembly. This dynamic design resolves the contradiction by providing stability without permanent bonding, thus improving reusability.
4Stability of the object's composition
If no movement is allowed between pipe joints, then the positional stability is improved, but the vibration absorption capability is worsened
Solution Approach 1:
The resilient element introduces controlled movement capability between couplers, allowing the joint to absorb vibrations from fluid flow while maintaining positional stability during normal operation. This resolves the contradiction by enabling movement only when needed for vibration absorption.
Solution Approach 2:
The resilient element acts as a pre-positioned cushion that absorbs vibrations before they can cause damage to the pipe joint. This beforehand cushioning resolves the contradiction by providing vibration protection while maintaining positional stability through the cushioning action.

AI summary
Apparatus for joining a first conduit to a second conduit comprising a first coupler for attachment to an end of the first conduit, a second coupler for attachment to an end of the second conduit and for engagement to the first coupler, and a snap-fit fastener for fastening the first coupler to the second coupler. The snap-fit fastener is arranged in at least two portions to fit around the periphery of the first and second couplers when the first and second couplers are engaged. The apparatus enables relative movement between the first coupler and the second coupler.
