Nested Sleeve Pipe Connector for Leak-Resistant Outlet Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water management systems, such as stormwater and sanitary sewer management systems, suffer from poor connections between underground mainline pipes and outlet pipes, leading to fluid leakage.
Innovation Solution
A system comprising a first sleeve on an outlet pipe with a lip abutting the mainline pipe interior and a second sleeve with a lip abutting the mainline pipe exterior, secured by fasteners and ridges to inhibit movement, ensuring a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection methods are used between mainline pipes and outlet pipes, then the device complexity is low, but the reliability of fluid containment deteriorates due to poor connections and fluid leakage
Solution Approach 1:
The connection system uses nested sleeves where an inner sleeve is positioned within an outer sleeve, both surrounding the outlet pipe. The inner sleeve has an interior lip that contacts the mainline pipe interior, while the outer sleeve has an exterior lip that contacts the mainline pipe exterior. This nested configuration provides multiple sealing surfaces and structural support layers, significantly improving fluid containment reliability without requiring completely separate connection components.
Solution Approach 2:
The connection system divides the sealing and support functions into distinct segmented components: the inner sleeve handles interior sealing and support, the outer sleeve provides exterior sealing and structural reinforcement, and fasteners secure the assembly. This segmentation allows each component to be optimized for its specific function while working together to solve the fluid leakage problem.
2Stability of the object's composition
If simple connection methods are used, then the ease of manufacture is high, but the connection stability deteriorates leading to poor connection between pipes
Solution Approach 1:
The nested sleeve configuration provides inherent stability through multiple concentric layers that support each other. The inner sleeve stabilizes the interior connection, while the outer sleeve reinforces the exterior connection. This nested structure naturally resists displacement and maintains connection stability without requiring complex assembly procedures or specialized manufacturing processes.
Solution Approach 2:
The sleeves are pre-formed with integrated lips and fastening mechanisms before installation. The interior and exterior lips are already positioned at the correct locations on the sleeves, and fastener recesses are pre-formed. This preliminary preparation of connection features simplifies the actual installation process while ensuring stable, reliable connections between the outlet pipe and mainline pipe.

AI summary
The embodiments of the present disclosure provide a system for connecting a mainline pipe with an outlet pipe. The system comprises an outlet pipe configured to be coupled to a mainline pipe near a proximal end of the outlet pipe, a first sleeve disposed on an exterior surface of the outlet pipe and comprising a first lip at a proximal end of the first sleeve, and a second sleeve disposed on the first sleeve and comprising a second lip at a proximal end of the second sleeve. The first lip of the first sleeve may be configured to abut an interior surface of the mainline pipe, and the second lip of the second sleeve may be configured to abut an exterior surface of the mainline pipe.
