Plug-In Connection Sealing With O-Ring Retention Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connection arrangements for components, such as motor housings, often require additional transport securing elements to prevent disconnection during assembly, leading to increased production costs and inefficiencies, particularly since wire snap rings do not provide a sealing function effectively.
Innovation Solution
A plug-in connection arrangement featuring a resilient connection element, like an O-ring, that allows for both retention and sealing engagement positions, enabling secure transport and operation while minimizing production complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a wire snap ring is used to secure components during transport, then retention is improved, but sealing function deteriorates and device complexity increases
Solution Approach 1:
The patent combines the retention function and sealing function into a single integrated component - the resilient connection arrangement element. This element simultaneously provides mechanical retention through its resilient engagement with the grooves and sealing through its deformable body that fills the gap between components, eliminating the need for separate wire snap ring and seal components
Solution Approach 2:
The resilient connection arrangement element serves multiple functions: it provides retention by engaging with the annular grooves to prevent component separation, provides sealing by deforming to fill gaps between components, and enables easy assembly through its resilient properties that allow temporary disengagement and re-engagement
2Stability of the object's composition
If a wire snap ring is used for retention, then retention is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the retention function and sealing function into a single integrated component - the resilient connection arrangement element. This element simultaneously provides mechanical retention through its resilient engagement with the grooves and sealing through its deformable body that fills the gap between components, eliminating the need for separate wire snap ring and seal components
Solution Approach 2:
The resilient connection arrangement element is designed to be self-retaining through its elastic properties. The element automatically engages with the grooves when components are assembled and maintains retention without requiring additional fastening operations or specialized assembly tools, thereby simplifying the manufacturing process
3Stability of the object's composition
If additional transport securing elements are used, then retention is improved, but assembly complexity increases
Solution Approach 1:
The patent combines the retention function and sealing function into a single integrated component - the resilient connection arrangement element. This element simultaneously provides mechanical retention through its resilient engagement with the grooves and sealing through its deformable body that fills the gap between components, eliminating the need for separate wire snap ring and seal components
Solution Approach 2:
The resilient connection arrangement element utilizes dynamic elastic deformation to facilitate assembly. The element can be temporarily deformed to allow component insertion, then automatically returns to its original shape to provide retention, enabling a simple single-step assembly process without complex fastening operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures reliable sealing and retention of components during transport and operation, reducing production costs and assembly complexity by using a standard, industrially produced O-ring for both functions, allowing for easy manual or automated transition between positions without additional assembly steps.
Implementation Method 1
via a resilient connection arrangement element arranged between the first portion and the second portion in the second annular groove, the first portion and the second portion can have a retention position relative to each other
Implementation Method 2
The second position is a sealing engagement position

AI summary
A plug-in connection arrangement for a component includes a first portion having a first groove contour in a first annular groove arranged in the first portion, and a second portion having a second groove contour in a second annular groove arranged in the second portion. Via a resilient connection arrangement element arranged between the first portion and the second portion in the second annular groove, the first portion and the second portion can have a retention position relative to each other in a first position and which can be moved in an axial direction into a second position which is provided for operation. The second position is a sealing engagement position.
