Plug-In Connection Sealing Lock for Airtight Component Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pluggable connection arrangements for components, such as motor housings, face challenges in providing a sealed connection that can be reliably maintained during operation while also being cost-effective and easy to assemble, as they often require additional sealing elements that increase production costs and complexity.
Innovation Solution
A pluggable connection arrangement featuring a first and second part with annular grooves and an elastic connection element, such as an O-ring, that transitions from a holding position for transport to a sealing detent position for operation, ensuring airtight sealing without additional assembly steps and allowing for easy disassembly and replacement of the connection element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire snap ring is used to fasten two parts of a connection arrangement, then the connection can be established, but the sealing function cannot be provided and the ring can be removed or replaced
Solution Approach 1:
The patent combines the fastening function and sealing function into a single integrated solution. The elastic connection arrangement element (O-ring) serves both to secure the first part to the second part and to provide sealing between them, eliminating the need for separate fastening and sealing components.
Solution Approach 2:
The elastic connection arrangement element performs multiple functions simultaneously: it acts as a fastening element to hold the connection arrangement together, provides sealing to prevent leakage, and enables the transition between holding position and sealing detent position. This multi-functionality resolves the contradiction by making one component do the work of multiple components.
2Reliability
If additional transport safety elements are used to seal a pluggable connection arrangement at the factory, then the connection can be protected, but production costs increase
Solution Approach 1:
The elastic connection arrangement element serves as both the operational sealing element and the transport safety element. During factory assembly, the element is in a first position providing protection, and during operation, it transitions to a second position providing sealing. This eliminates the need for separate transport safety elements, reducing production costs while maintaining protection capabilities.
Solution Approach 2:
The elastic connection arrangement element is designed to be movable between a first position (for transport and factory assembly) and a second sealing detent position (for operation). This dynamic capability allows the same element to fulfill different protective functions at different stages, eliminating the need for additional static protective elements.
3Reliability
If multiple sealing elements are used in a connector, then sealing is improved, but the device complexity and assembly steps increase
Solution Approach 1:
The patent merges the functions of multiple sealing elements into a single elastic connection arrangement element (O-ring). This single element provides the sealing function that would otherwise require multiple separate sealing rings, thereby reducing device complexity while maintaining sealing performance.
Solution Approach 2:
The elastic connection arrangement element provides both fastening and sealing functions simultaneously, replacing what would traditionally require separate fastening elements and multiple sealing elements. This multi-functionality reduces the total number of components needed while ensuring reliable sealing.
