Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deaerating apparatuses for motor vehicle gear mechanisms have either a high structural space requirement or inadequate oil separation capacity, making them unsuitable for compact and high-functionality applications.
Innovation Solution
A compact deaerating apparatus with an additional aerosol trap, featuring a labyrinth region with impact walls, is introduced to improve liquid separation from aerosols. The aerosol trap is designed as a separate component with a slim configuration, allowing for retrofitting in existing systems and reducing the structural space requirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional deaerating apparatus is used, then the structural space requirement is reduced, but the oil separation capacity is insufficient
Solution Approach 1:
The aerosol trap is integrated into the access line as an internal component, nesting the separation function within the existing fluid conveyage path. This allows the deaerating apparatus to achieve enhanced oil separation capacity without proportionally increasing the overall device volume, as the aerosol trap utilizes the space already allocated for fluid transport.
Solution Approach 2:
The deaerating apparatus is divided into functional segments: the access line for fluid conveyage and the integrated aerosol trap for separation. This segmentation allows the oil separation function to be added as a distinct component within the access line structure, improving separation capacity while maintaining a compact overall form factor.
2Reliability
If the deaerating membrane is directly exposed to aerosol, then the deaerating functionality is maintained, but the membrane is subjected to high liquid load reducing its service life
Solution Approach 1:
The aerosol trap is positioned upstream of the deaerating membrane within the access line, performing preliminary separation of liquid from aerosol before the fluid reaches the membrane. This preliminary action reduces the liquid load on the membrane, protecting it from excessive wetting and extending its service life while maintaining deaerating functionality.
3Adaptability or versatility
If a compact deaerating apparatus is designed, then the structural space requirement is reduced, but the functionality and oil separation capacity are compromised
Solution Approach 1:
The access line serves multiple functions: it conveys fluid from the internal space to the deaerating device and simultaneously houses the aerosol trap for oil separation. This multi-functionality allows the compact apparatus to achieve enhanced functionality with minimal increase in structural space, as the same physical space performs dual roles.
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 proposed solution achieves a high degree of liquid separation from aerosols, reducing the liquid load on the deaerating membrane and enhancing its functionality and service life, while maintaining a compact structure.
Implementation Method 1
a membrane is arranged in the deaerating device and a gas exchange and therefore the deaerating functionality are thereby carried out between the apparatus to be deaerated and the environment which surrounds this apparatus
Implementation Method 2
the deaerating labyrinth is configured to separate liquid from a gas in which liquid in the form of drops is received, so-called aerosol

AI summary
A deaerating device is provided for a drive component in a motor vehicle. The deaerating device has an access line, a membrane deaerator, which includes a deaerating membrane, and an discharge air side. The deaerating device is designed to fluidically connect the interior of a drive component to the area surrounding the drive component. The deaerating membrane is arranged downstream of the access line and upstream of the discharge air side in a planned flow direction from the drive component into the area surrounding the drive component. The access line has an aerosol trap which has a labyrinth element for accumulating liquid on at least one wall of the labyrinth element, and the aerosol trap is designed as a separate component with respect to the access line and the membrane deaerator.
