Pipe Connection Locking Ring for Leak-Tight Corrugated Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for pipes with outer peripheral projections struggle to achieve a reliable, sealing connection, particularly for corrugated pipes, due to movement and leakage issues.
Innovation Solution
A connection device comprising a receptacle with a central axis and a peripheral wall, a ring element that surrounds the pipe, and a securing part made of deformable material, which forms a block to prevent the ring element from moving out, ensuring a fluid-tight connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple receptacle structure is used for inserting pipes, then the device complexity is reduced, but the reliability of sealing connection deteriorates due to pipe movement and leakage
Solution Approach 1:
The connection device is divided into distinct functional segments: the receptacle for insertion, the ring element for positioning and sealing, and the securing part for locking. This segmentation allows each component to perform its specific function optimally while maintaining overall simplicity
Solution Approach 2:
The ring element acts as an intermediary component between the pipe and the receptacle. It provides the sealing function and prevents pipe movement without requiring complex integrated structures, thus maintaining simplicity while improving reliability
2Reliability
If a ring element is added to prevent pipe movement, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The ring element serves multiple functions simultaneously: it acts as a sealing element, a positioning element to prevent radial movement, and a support for the securing part. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity
3Reliability
If a deformable securing part is used to lock the ring element, then the connection reliability is improved, but the ease of operation deteriorates due to additional forming steps
Solution Approach 1:
The securing part utilizes material property changes (deformation) to achieve locking. The deformable material allows the securing part to be inserted in a flexible state and then locked in place through deformation, providing reliable connection without requiring complex mechanical locking mechanisms
Solution Approach 2:
The deformable securing part is designed to lock itself through material deformation. Once inserted and deformed, it automatically secures the ring element without requiring additional tools or complex operating steps, balancing reliability with ease of operation

AI summary
A connection device for a pipe with an outer peripheral projection comprises a connection part with a receptacle for inserting a longitudinal portion of the pipe. The portion comprises the projection, therein. A central axis extends in an insertion direction. A peripheral wall extends around the central axis. A base surface is arranged transversely to the central axis for contacting the projection of the pipe or an end of the pipe. A ring element can be introduced into a gap between the peripheral wall and the pipe such that an axial end of the ring element blocks the projection and secures the pipe against moving out of the receptacle. A securing part is assigned to the connection part and has at least one deformable material portion which can be brought into a blocking position by deformation to form a block against the ring element moving out of the receptacle.
