Filter Cover Fluid Channel and Dual Seal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems for internal combustion engines, particularly in commercial vehicles, face challenges in efficiently exchanging filter elements due to clogging and limited installation space, requiring complex sealing mechanisms and secure mounting solutions.
Innovation Solution
A filter system with a cover featuring a fluid channel at its inner side, connected to the filter element, and a seal comprising two sealing rings connected by flanks, allowing for easy exchange and secure sealing of the filter element, while also guiding clean fluid efficiently through the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex sealing mechanism is used to securely mount the filter element, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The seal is divided into two separate sealing rings instead of using a single complex sealing mechanism. Each sealing ring handles a specific sealing function, simplifying the overall design while maintaining reliable sealing. The first sealing ring seals between the cover and housing part, and the second sealing ring seals at the opening, dividing the sealing function into manageable segments.
Solution Approach 2:
The seal acts as an intermediary component between the cover and the housing part, providing a dedicated sealing interface. This intermediary element isolates the sealing function from the main structural components, allowing for simpler overall design while ensuring reliable sealing through the specialized seal component.
2Reliability
If the filter element is securely clamped in the housing, then the mounting reliability is improved, but the ease of exchange deteriorates
Solution Approach 1:
The mounting system is segmented into the housing part, cover, and seal components, allowing the filter element to be securely held during operation but easily accessed when the cover is removed. The segmentation enables independent access to the filter element without affecting the structural integrity of the housing.
Solution Approach 2:
The mounting system transitions from a static secure clamping to a dynamic state where the cover can be easily removed and reinstalled. The filter element remains securely mounted during operation, but the removable cover provides dynamic access for exchange, balancing security with ease of maintenance.
3Volume of moving object
If inlet and outlet are arranged in the same housing part, then the installation space requirement is reduced, but the fluid flow path becomes more complex
Solution Approach 1:
The inlet and outlet connections are merged into the same housing part (the cover), reducing the overall installation space required. The fluid channel within the cover integrates the flow path, combining what could be separate components into a single integrated structure, thereby saving space while managing the flow complexity internally.
Solution Approach 2:
The fluid flow path is arranged in three-dimensional space within the cover, utilizing vertical and radial dimensions to route fluid from inlet to outlet. This spatial arrangement accommodates the complex flow path within a compact volume by using multiple dimensions rather than extending linearly.

AI summary
A cover for a filter system for filtering a fluid has a fluid channel arranged at an inner side of the cover. The cover has a rim and at least one opening arranged in the rim to allow the fluid to pass through, wherein the opening is connected in fluid communication with the fluid channel. The fluid channel is connected in fluid communication with the interior of a filter element of the filter system. A seal for the cover has a first sealing ring and a second sealing connected to each other by flanks. The filter system has a housing with a housing part that is closable by the cover. A filter element is exchangeably arranged in the housing, and the fluid channel of the cover is connected in fluid communication to the interior of the filter element.
