Deformable Closing Body for Regulated Airflow in Fluid Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid passage closing mechanisms in motor vehicles lack the ability to provide a regulated and adjustable air supply that can both fully close and partially open the passage while maintaining a fluid-tight seal.
Innovation Solution
A closing apparatus with a deformable base structure surrounded by a wrapper, comprising rods attached to rotating retaining plates, allows for adjustable fluid passage control by twisting the plates, enabling a transition from a closed, cylindrical shape to an opened, hyperboloidal shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing body is used to completely close the fluid passage, then sealing performance is improved, but the ability to regulate airflow is lost
Solution Approach 1:
The closing body employs a deformable base structure that can dynamically change its shape between a closed cylindrical configuration (for sealing) and an opened hyperboloidal configuration (for airflow regulation). This dynamic transformation allows the same component to provide both complete sealing and regulated airflow control.
Solution Approach 2:
The invention changes the geometric parameters of the closing body by deforming the base structure. The rod arrangement and wrapper configuration are transformed from one shape to another, altering the effective cross-sectional area of the closing body to transition between sealed and regulated states.
2Adaptability or versatility
If a deformable base structure with wrapper is used to enable adjustable fluid passage, then airflow regulation is improved, but structural complexity increases
Solution Approach 1:
The base structure is segmented into multiple rods of equal length that are hinged to retaining plates. This segmentation allows the structure to deform in a controlled manner while maintaining manufacturing simplicity and structural integrity during transformation.
Solution Approach 2:
The wrapper acts as a flexible shell that surrounds the rod structure and maintains the deformable shape. The flexible material allows the base structure to transform between cylindrical and hyperboloidal configurations while maintaining fluid-tight sealing.
3Productivity
If the closing body is fully deformed to opened position, then fluid passage is released, but complete opening is prevented
Solution Approach 1:
The closing body is designed to provide partial opening of the fluid passage rather than complete removal. The deformed state creates a hyperboloidal shape that releases enough fluid passage for adequate airflow while maintaining the closing body within the passage for continued regulation capability.
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 apparatus provides a fluid-tight seal in the closed position and adjustable opening in the opened position, facilitating regulated airflow control in motor vehicles.
Implementation Method 1
the base structure with the wrapper takes up a closed position, wherein the closing body closes the fluid passage... the base structure with the wrapper takes up an opened position

AI summary
A closing apparatus for a fluid passage having a closing body arranged in the fluid passage. In order to simplify the regulated air supply in a motor vehicle, the closing body includes a definedly deformable base structure surrounded by a wrapper, which more or less closes the fluid passage as a function of the deformation of the base structure. The closing body closes the fluid passage when the base structure takes up a closed position with the wrapper. And, the closing body partially releases the fluid passage when the base structure with the wrapper takes up an opened position.
