Ball Valve Bottle Coupling for Leak-Free Cleaning Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face issues with sealing tightness between the fluid coupling and retaining cylinder and the storage container, leading to unintentional discharge of cleaning fluid and contamination.
Innovation Solution
A fluid flow assembly featuring a ball valve assembly with a male coupling that penetrates into an outlet port of the storage container, displacing a valve ball from a closed to an open position for controlled fluid flow, and a bayonet fitting for secure attachment, along with a guide wall and mounting wall for precise alignment and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple coupling piece with cannula is used for connecting storage container to fluid coupling, then the device complexity is reduced, but the sealing tightness deteriorates leading to unintentional discharge of cleaning fluid
Solution Approach 1:
A sealing element is introduced as an intermediary component between the coupling piece and the fluid coupling retaining cylinder. This sealing element prevents cleaning fluid from passing through the coupling interface, thereby resolving the sealing tightness issue without complicating the overall coupling structure.
Solution Approach 2:
A flexible sealing ring or membrane is employed at the coupling interface to create a reliable seal. The flexible nature of this thin film component allows it to conform to the coupling surfaces, preventing leakage while maintaining a simple coupling design.
2Ease of operation
If a simple coupling piece with cannula is used for connecting storage container to fluid coupling, then the ease of operation is improved, but the sealing tightness deteriorates causing contamination
Solution Approach 1:
The sealing element acts as a mediator that prevents harmful leakage of cleaning fluid while maintaining the simple and easy-to-operate coupling mechanism. Users can still easily connect and disconnect containers, but the sealing element prevents contamination.
3Ease of operation
If the storage container is held in a releasable manner on the fluid coupling and retaining cylinder, then the ease of operation for changing containers is improved, but the sealing tightness deteriorates leading to uncontrolled discharge
Solution Approach 1:
The sealing element is positioned at the coupling interface to maintain fluid integrity during the releasable connection and disconnection process. It ensures that cleaning fluid remains contained until the container is properly connected, preventing uncontrolled discharge during operation.

AI summary
A fluid flow assembly includes a storage container connected to a fluid coupling and retaining cylinder. The connection is secured by a bayonet connection and walls between the bases of the container and cylinder. The storage container has a ball valve assembly disposed at its base, which includes an upper housing, a lower extension, and a ball valve axially disposed therein. The cylinder includes an axial hollow elongate fluid outlet on the base, co-axially aligned with an outlet port of the ball valve assembly of the container. The upper portion of the fluid outlet is a male coupling, which penetrates into the outlet port, when the container is connected to the cylinder, and axially displaces a valve ball from its closed position into an open position, enabling fluid flowing thru the ball valve assembly of the storage container, into the hollow fluid outlet of the cylinder, and downstream of it.
