Tapered Annular Joint Assembly for Pipe Diameter Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aftertreatment systems for internal combustion engines face challenges in minimizing cost while maintaining a compact arrangement, as rigid pipes require additional transitional pipework to connect pipes of different sizes, increasing system size and complexity.
Innovation Solution
A joint assembly with an annular section and clamp portion that gradually transitions between pipes of different diameters, providing a smooth flow path and rotational flexibility, eliminating the need for additional transitional pipework and allowing for a more compact system design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rigid pipes are used to connect pipes of different sizes, then cost is reduced, but additional transitional pipework is required which increases system size
Solution Approach 1:
The joint assembly merges the transition function and connection function into a single integrated component. The annular section provides the diameter transition while the clamp portions provide the connections, eliminating the need for separate transitional pipework and reducing overall system size.
Solution Approach 2:
The joint assembly performs multiple functions simultaneously: it transitions between different pipe diameters, provides mechanical connection for both pipes, and maintains flow path continuity. This multi-functionality replaces what would traditionally require multiple separate components.
2Ease of operation
If additional transitional pipework is added to connect pipes of different sizes, then connection is achieved, but system complexity increases
Solution Approach 1:
The joint assembly combines the transition function and connection function into a single integrated component. The annular section provides the diameter transition while the clamp portions provide the connections, eliminating the need for separate transitional pipework and reducing overall system size.
3Volume of stationary object
If flexible pipes are used for conduits, then compact arrangement is facilitated, but system cost increases
Solution Approach 1:
The joint assembly changes the geometric parameters of the flow path through its tapered annular section, gradually transitioning from the smaller inner diameter to the larger inner diameter. This parameter change enables smooth flow transition while maintaining rigid pipe construction.

AI summary
A joint assembly for connecting a first pipe having a first inner diameter and a second pipe having a second inner diameter which is larger than the first inner diameter comprises, an annular section comprising an annular wall defining a flow path through the annular section and configured to connect to the first pipe and the second pipe, and a clamp portion configured to clamp the second pipe between an outer surface of the annular section and an inner surface of the clamp portion. An inner diameter of the annular section varies from a first inner diameter at a first end of the annular section to a second inner diameter at a second end of the annular section. The first inner diameter is substantially equal to the inner diameter of the first pipe. The second inner diameter is substantially equal to the inner diameter of the second pipe.
