Eccentric Multi-Diameter Flue Gas Adapter for Secure Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flue gas outlet adapters are limited in accommodating multiple pipe diameters and often fail to securely fasten pipes, which does not meet stringent safety and regulatory standards, especially in countries with specific requirements.
Innovation Solution
A multi-diameter adapter with eccentrically disposed and mutually tangent cylinder-shaped walls, equipped with a pipe securing member and sealing rings, allowing secure engagement and sealing of pipes of various diameters, and a manually operable tightening mechanism for easy installation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-diameter adapter design is used, then the adapter structure is simple, but it cannot accommodate multiple pipe diameters
Solution Approach 1:
The adapter is segmented into multiple cylindrical chambers (first chamber, second chamber, third chamber) with different internal diameters, each capable of receiving a pipe of corresponding diameter. This segmentation allows a single adapter to accommodate multiple pipe sizes without requiring separate adapters for each diameter.
Solution Approach 2:
The adapter is designed as a universal component that can receive and secure pipes of different diameters (e.g., 60mm, 80mm, 100mm) through its multi-chamber structure. The pipe securing member can clamp onto pipes of various diameters, making the adapter versatile for different pipe sizes.
2Reliability
If no pipe securing member is used, then the adapter structure is simpler, but the pipe cannot be securely fastened meeting safety standards
Solution Approach 1:
The pipe securing member integrates multiple functions into a single component: it secures the pipe to the adapter, provides a sealing interface, and ensures proper alignment. This merging of functions achieves reliable pipe fastening while minimizing the number of separate components needed.
Solution Approach 2:
The adapter structure is designed with pre-positioned securing features and sealing surfaces that prepare the connection interface before the pipe is fully inserted. The pipe securing member is positioned to automatically engage with the pipe upon insertion, ensuring secure fastening without requiring additional adjustment steps.
3Reliability
If separate pipe securing members are used for each pipe diameter, then secure fastening is achieved, but the number of components increases
Solution Approach 1:
A single pipe securing member is designed to universally secure pipes of different diameters. The securing member can be adjusted or is designed with a clamping mechanism that adapts to various pipe sizes (60mm, 80mm, 100mm), eliminating the need for multiple dedicated securing members for each pipe diameter.
Solution Approach 2:
The pipe securing member incorporates dynamic adjustment capabilities, allowing it to adapt its clamping force and positioning to accommodate pipes of different diameters. This dynamic design enables a single component to perform the function of multiple fixed-size securing members.

AI summary
Adapter for a flue gas outlet with a first end (2), a second end (4), and a central passageway (6) extending there between. The second end (4) has at least two interconnected cylinder shaped walls (8, 10, 12) having different internal diameters (d1, d2, d3), each cylinder shaped wall (8,10,12) being arranged for sealed engagement with a corresponding pipe to be inserted into the adapter (1). An internal diameter of the at least two cylinder shaped walls (8,10,12) decreases with increased insertion depth (h) as measured from the second end (4) toward the first end (2). The at least two cylinder shaped walls (8,10,12) are eccentrically disposed and mutually tangent in a longitudinal direction of the adapter (1). The adapter (1) further has a pipe securing member (14) circumferentially disposed at the second end (4).
