Dual-Sealed Quick Connector for Air Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick connectors suffer from limited sealing effectiveness, leading to air leakage during connection due to reliance on a single sealing ring, which compromises the connection's integrity.
Innovation Solution
Incorporating a metal inner bushing with an insertion slot, an annular slot, a wall sealing ring, a groove on the inner end surface, and a rubber end surface gasket with perforations, along with a plug insertion portion, to enhance sealing by utilizing dual sealing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a sealing ring is used for sealing, then the structure is simple, but the sealing effectiveness is limited and air leakage occurs
Solution Approach 1:
The sealing function is segmented into two independent sealing rings: a first sealing ring for wall sealing and a second sealing ring for end surface sealing. Each sealing ring addresses a specific sealing need, allowing the system to achieve comprehensive sealing without excessive complexity by dividing the sealing task into manageable segments.
Solution Approach 2:
Different sealing solutions are applied to different locations: the first sealing ring is positioned in the annular slot for wall sealing, while the second sealing ring is positioned in the groove for end surface sealing. This local differentiation optimizes sealing effectiveness at each critical location without requiring a complex unified sealing structure.
2Reliability
If a single sealing ring is used, then the manufacturing process is simple, but air leakage occurs at the end
Solution Approach 1:
The sealing system is segmented into two separate sealing rings with distinct functions and positions. The first sealing ring handles wall sealing while the second sealing ring handles end surface sealing, allowing each component to be manufactured and assembled independently, which maintains manufacturing simplicity while improving connection integrity.
Solution Approach 2:
The second sealing ring acts as an intermediary element specifically addressing the end surface sealing issue. By introducing this intermediate sealing component between the plug and the outer shell, the patent eliminates air leakage at the end without fundamentally redesigning the entire manufacturing process.
3Reliability
If dual sealing mechanism is added, then complete sealing is achieved, but the structure becomes more complex
Solution Approach 1:
The dual sealing mechanism is implemented through segmentation of the sealing function into two distinct rings positioned at different locations. This segmentation allows each sealing ring to be optimized for its specific function while maintaining overall structural simplicity, as each ring is a separate, straightforward component rather than a complex integrated system.
Solution Approach 2:
Each sealing ring is designed with local quality appropriate to its function: the first sealing ring is configured for wall contact and sealing, while the second sealing ring is configured for end surface contact. This local optimization achieves complete sealing without requiring complex overall structure, as each component is simple but well-suited to its specific sealing location.

AI summary
The present invention provides a quick connector, which includes a socket and a plug. The socket includes an inner bushing arranged therein, an insertion slot arranged in the inner bushing, an annular slot arranged on a wall surface of the insertion slot, and a wall sealing ring arranged in the annular slot. The plug includes an insertion portion arranged thereon and inserted into the insertion slot, and the wall sealing ring is sleeved on the outer wall of the insertion portion. The socket includes a groove arranged on an inner end surface of the insertion slot in the inner bushing, and an end surface gasket arranged in the groove. The end surface of the plug is abutted against the end surface gasket of the socket. The quick connector is double sealed by the end surface gasket and the wall sealing ring.
