Air Filter Element Radial Seal Monolithic End Disk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter systems for internal combustion engines face challenges in simplifying the exchange of filter elements, particularly due to the clogging of filter media and the need for secure attachment within the filter housing.
Innovation Solution
The air filter system incorporates a filter element with a clean air seal that is monolithically formed with a first end disk, allowing for radial protrusion past the filter medium. This design simplifies the configuration of the filter housing and facilitates easy exchange of the filter element by ensuring a secure seal-tight contact with the filter housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter element is securely attached in the filter housing, then the sealing performance is improved, but the exchange of the filter element becomes more difficult
Solution Approach 1:
The filter element is divided into functionally independent components: the filter medium for filtration and the clean air seal for sealing. The clean air seal is embodied as a separate one-piece component that can be easily removed and replaced, allowing the sealing function to be maintained while simplifying the exchange process. The filter medium remains embedded in the end disk, separating the filtration function from the sealing function.
Solution Approach 2:
The clean air seal is extracted as a distinct component from the filter medium. The seal is embodied as one piece with the end disk but can be easily detached, allowing the sealing function to be independently maintained while the filter medium is replaced during routine maintenance.
2Reliability
If the clean air seal protrudes radially past the filter medium, then the sealing ability is improved, but the device complexity increases
Solution Approach 1:
The clean air seal is merged with the end disk as a one-piece monolithic component. This integration simplifies the overall structure by eliminating the need for separate sealing components and assembly steps, while the radial protrusion of the seal past the filter medium ensures effective sealing between the filter element and filter housing.
Solution Approach 2:
The end disk serves multiple functions: it provides structural support for the filter medium, creates the clean air seal through its radially protruding portion, and facilitates the embedding of the filter medium. This multi-functionality reduces the number of separate components needed in the filter element.

AI summary
An air filter element for an air filter for an internal combustion engine is provided with a filter medium surrounding annularly a longitudinal axis of the air filter element. A first end disk is provided at a first end face of the air filter element, wherein the filter medium is embedded in the first end disk at the first end face. A clean air seal is configured to seal a raw side of the air filter against a clean side of the air filter. The clean air seal and the first end disk are embodied together as one piece. The clean air seal protrudes continuously radially past the filter medium. A filter housing for the air filter element is provided with a filter pot and a cover and has a clean air outlet and a raw air inlet arranged at a side wall of the filter pot.
