Fluid Line Coupling Socket Layout for Low-Turbulence Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling devices for fluid lines often suffer from deteriorated fluid dynamics at the coupling point due to turbulence and dead areas, which can lead to uncontrolled fluid escape and potential environmental damage.
Innovation Solution
The coupling device incorporates a recording unit with a wave spring that is arranged radially outside the cylindrical section, reducing installation space while maintaining spring force. This design minimizes turbulence and dead areas by guiding fluid flow effectively through interruptions in the locking element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring element is preloaded into a specific position by spring elements, then the closure element is held in a specific position (open or closed), but the spring element causes severe disruption of the fluid flow in the area of the coupling device
Solution Approach 1:
The spring element is extracted from the fluid flow path and positioned in a recess of the closure element, separated from the fluid flow. This allows the spring to maintain the closure element in the desired position without causing turbulence or dead zones in the fluid flow.
Solution Approach 2:
The spring element is nested within a recess of the closure element, placing it inside a designated space that does not interfere with the fluid flow path. This nesting approach allows the spring to function while remaining hidden from the fluid stream.
2Reliability
If the closure element is positioned to seal or open the fluid flow channel, then fluid flow control is achieved, but dead zones can lead to accumulation of fluid within the coupling device
Solution Approach 1:
The spring element is extracted from potential dead zones and positioned within the closure element's recess, eliminating areas where fluid could accumulate. The design ensures that the spring does not create pockets or cavities that would trap fluid.
3Device complexity
If the spring element is arranged within the fluid flow path, then compact design is achieved, but turbulence and dead zones are created
Solution Approach 1:
The spring element is nested within the closure element's recess, utilizing the existing structure to house the spring without adding external complexity. This nesting achieves compact design while keeping the spring separated from the fluid flow path.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The improved fluid dynamics reduce turbulence and dead areas, preventing fluid accumulation and uncontrolled escape, thus enhancing safety and reducing the risk of environmental pollution.
Implementation Method 1
the spring element can be a wave spring. Compared to a coil spring, a wave spring requires less space while providing the same spring force.
Implementation Method 2
its closure element (20) provided with an end face for abutment against the plug-in unit (14), in a closed position configured to fluidically seal the fluid flow channel of the receiving unit (12) between a first end (16) and the second end (18)
