Low-Resistance Line Connector With Segmented Valve Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connectors with valves exhibit high flow resistance due to their design, which is not addressed by existing technologies, and existing connectors with valves connectors are not designed to reduce this resistance effectively.
Innovation Solution
The pipe connector design includes a valve seat with non-concentrically arranged flow openings, such as star or flower-shaped, and an axially sliding valve guide integrated into the valve seat, eliminating the need for a separate valve holder, thereby reducing flow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a valve is arranged in the inner channel of a pipe connector, then fluid loss during disconnection is avoided, but flow resistance increases significantly
Solution Approach 1:
The flow opening is segmented into multiple separate openings instead of a single large opening. This segmentation increases the total circumference of the flow path while maintaining adequate flow area, thereby reducing flow resistance while still allowing the valve to effectively control fluid loss during disconnection
Solution Approach 2:
The flow opening deviates from a conventional circular shape to an asymmetric shape (such as star-shaped or flower-shaped). This asymmetric geometry increases the circumference of the flow path, which reduces flow resistance and improves fluid flow characteristics while the valve body can still seal against the valve seat
2Reliability
If a separate valve holder is used to mount the valve guide, then the valve structure is stable, but device complexity and flow resistance increase
Solution Approach 1:
The valve guide is integrated directly into the valve seat, merging two previously separate components (valve guide and valve seat) into a single integrated structure. This eliminates the need for a separate valve holder, reduces the number of components, and removes additional flow resistance that would be created by extra structural elements
Solution Approach 2:
The valve seat is designed to serve multiple functions: it provides the sealing surface for the valve body, guides the valve body movement, and eliminates the need for a separate mounting structure. This multi-functional design simplifies the overall valve assembly while maintaining structural stability and reliability

AI summary
A fluidic coupling connector 1 with a complementary coupling connector 2 comprises a connector body 3. A valve 10 is arranged in an inner channel 8 of the connector body 3, the valve 10 having a valve guide 11, an axially movable valve body 12, and a valve seat 13. The valve guide 11 defines the direction of movement of the valve body 12, the coupling connector 1 being designed such that the valve body 12 is fluid-tight against the valve seat 13 when the valve 10 is closed. The valve seat 13 is provided to have at least one flow opening 7, the cross-section of which deviates from a circular shape arranged concentrically with respect to the central axis M, and/or the valve guide 11 is axially slidably mounted in a guide receptacle 16 of the valve seat 13.
