Problem
Existing connection devices for aeration and venting elements in automotive transmissions are not easily mountable or dismountable while ensuring secure attachment and preventing impurities and moisture from entering the transmission interior space.
Innovation Solution
A connection device with a torsion ring and connecting rockers that form a form-fitting, latching connection to a membrane venting element, allowing for easy manual release without tools, ensuring secure attachment and preventing moisture entry while allowing gas exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection device uses a complex latching mechanism to ensure secure attachment, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The connection device employs a dynamic latching mechanism where the rocker lever can be easily actuated to release the latching connection. The resilient torsion ring provides automatic resetting after release, enabling simple manual operation while maintaining secure attachment during normal operation.
Solution Approach 2:
The resilient torsion ring automatically returns the rocker lever to its latched position after release, eliminating the need for additional components or complex mechanisms to reset the connection device. The system serves itself by using the stored elastic energy in the torsion ring.
2Ease of operation
If a connection device is designed for quick mounting and dismounting, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The connection device separates the mounting function into two distinct phases: a quick initial engagement phase where the connector is simply inserted, and a secure latching phase where the rocker lever automatically engages the latching connection. This segmentation allows quick mounting while ensuring reliable attachment.
3Ease of operation
If the connection device uses a resilient torsion ring for the latching mechanism, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connection device merges multiple functions into the single rocker lever component: it serves as the actuation lever for release, the latching element that engages with the counter, and the indicator of latched status. This merging reduces the number of separate components needed while maintaining ease of operation.
4Adaptability or versatility
If the venting element uses a membrane structure for gas permeability, then functionality is improved, but ease of manufacture deteriorates
Solution Approach 1:
The membrane venting element is designed as a universal component that can be integrated with different connection devices and transmission types. The standardized connection interface allows the same membrane venting element to be used across multiple applications, simplifying manufacturing and inventory management while maintaining the gas-permeable function.
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 connection device enables quick and secure mounting and dismounting of the venting element, maintaining a gas-permeable but liquid-impermeable seal, facilitating efficient air exchange while preventing impurities and moisture from entering the transmission.
Implementation Method 1
a gas-permeable but liquid-impermeable membrane
Implementation Method 2
a gas-permeable but liquid-impermeable membrane
Implementation Method 3
the torsion ring, and thus the connecting rocker, springs back into its original position again
Implementation Method 4
the torsion ring serves as a hinge device for the connecting rocker and preferably as a combined hinge-and-spring device

AI summary
A connection device for a ventilation element includes a transmission connection and a vent connection, the vent connection connects the connection device to a ventilation element, the component connection has a connection piece extending along a connecting axis, and a torsion ring surrounding the connection piece. A connecting rocker is arranged on the torsion ring, and the torsion ring is connected to the connection piece by a connecting bridge, and the connecting rocker has an actuation section and an engaging section for forming an interlocking connection. The torsion ring runs between the actuation section and the engaging section in a connecting region, in which it is connected to the connecting rocker, and the connecting bridge has a connecting arm, which starts from the connection piece and extends in the direction of the connecting axis up to the torsion ring and retains same at a radial distance from the connection piece.
