Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies for fluid communication between components fail to ensure a sealed state when disconnected and efficient fluid flow when connected, often leading to leaks or improper sealing.
Innovation Solution
A connector assembly comprising a male and female connector with integrated push rods and valve cores, featuring elastic devices and slope surfaces for sealing, allowing for easy assembly and disassembly while maintaining a sealed state when disconnected and enabling fluid communication when connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a male connector and female connector are used for fluid communication, then fluid can flow between components when connected, but the connectors may leak fluid when disconnected
Solution Approach 1:
The valve core is pre-configured in a closed position that automatically seals the fluid passage when the connector is disconnected. This preliminary sealing action prevents fluid leakage before disconnection occurs, eliminating the harmful effect of potential leaks during the transition state between connected and disconnected states.
Solution Approach 2:
The valve core acts as an intermediary element between the fluid passage and the external environment. When disconnected, the valve core closes the fluid passage, mediating between the internal fluid pressure and the external atmosphere to prevent harmful fluid leakage while maintaining the integrity of the fluid communication system.
2Ease of operation
If push rods are added to open valve cores for fluid communication, then fluid flow is enabled when connected, but the structure becomes more complex
Solution Approach 1:
The push rod is integrated with the connector housing as a single unified structure rather than being a separate component. This merging of the push rod with the housing simplifies the overall structure by reducing the number of discrete parts while maintaining the functionality of opening the valve core for fluid communication during assembly and disassembly operations.
Solution Approach 2:
The integrated push rod structure serves multiple functions: it acts as both a structural support element of the connector housing and as the actuating mechanism to open the valve core. This multi-functionality eliminates the need for separate components, simplifying the overall device structure while enabling easy assembly and disassembly operations.

AI summary
A connector assembly includes a male connector and a female connector. The male connector comprises a male connector housing, a male connector valve core, and a male connector push rod. The female connector comprises a female connector housing, a female connector valve core, and a female connector push rod. The male connector valve core has a closed position, the female connector valve core has a closed position, and the male connector is capable of being at least partially inserted into the female connector. When the male connector is inserted to a proper place in the female connector, the male connector push rod pushes the female connector valve core away from the closed position, and the female connector push rod pushes the male connector valve core away from the closed position, so that the male connector fluidly communicates with the female connector.
