Pipe Fitting Vibration Compensator for Noise Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press fitting systems are costly, require brand-specific tools, and often result in non-permanent seals and inadequate absorption of pipe expansions, vibrations, and noise due to rigid fixation.
Innovation Solution
A press fitting system with an elastic vibration compensator made from rubber-based materials, featuring a detachable design using standard tools, and a union nut mechanism for fluid-tight connections that can absorb vibrations and noise, eliminating the need for specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If press fittings are used to achieve non-detachable attachment and fluid-tight connection, then connection reliability is improved, but the ability to dismantle and adaptability is lost
Solution Approach 1:
The pipe connection system is divided into modular components: pipe sections, coupling elements with internal threads, and connection elements. This segmentation allows the connection to be assembled and disassembled by unscrewing the coupling element, providing adaptability while maintaining fluid-tight connection when assembled.
Solution Approach 2:
The connection system transitions from a static, permanent press fitting to a dynamic, adjustable threaded connection. The coupling element can be rotated and removed, allowing the connection to be reconfigured, dismantled, or adapted to different pipe configurations.
2Strength
If rigid fixation is used to ensure mechanical stability, then connection strength is improved, but vibration and noise absorption is reduced
Solution Approach 1:
The patent introduces flexible elements such as rubber seals and gaskets within the rigid threaded connection structure. These flexible components absorb vibrations and reduce noise transmission while maintaining the mechanical strength and stability of the overall connection through the threaded coupling mechanism.
3Manufacturing precision
If brand-specific pressing tools are required for assembly, then manufacturing precision is improved, but device complexity and cost increase
Solution Approach 1:
The threaded connection system uses standardized external and internal threads that can be assembled using general-purpose screwdrivers or wrenches, eliminating the need for brand-specific pressing tools. The universal threading standard allows the same connection elements to be used across different applications and brands, reducing device complexity and cost.
4Reliability
If press fittings are used to achieve permanent connection, then connection reliability is improved, but ease of operation and assembly time are reduced
Solution Approach 1:
Instead of using a complex pressing tool to create a permanent deformation connection, the patent inverts the approach by using a simple threaded fastening mechanism. The coupling element is screwed onto the pipe, creating a secure connection through friction and thread engagement, which can be achieved with simple hand tools rather than specialized pressing equipment.
