Oil Filter Element Integrated Sealing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil filter elements with radial and axial sealing elements are expensive to manufacture due to their complex design, requiring separate components and assembly steps.
Innovation Solution
The oil filter element integrates an elastically deformable radial sealing element formed from the inside circumferential section of the first end disk and an axially deformable axial sealing element held by retaining elements on the outside of the first end disk, allowing for simplified and cost-effective manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radial and axial sealing elements are designed as separate components, then sealing functionality is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent merges the radial sealing element and axial sealing element into a single integrated sealing component. The radial sealing element forms the inner circumference of the first end disk, while the axial sealing element is positioned on the outer circumference, both as unified structures that simplify manufacturing while maintaining effective sealing at both the outlet opening and the drain opening interfaces
2Ease of manufacture
If sealing elements are integrated into the end disk structure, then manufacturing cost decreases, but sealing effectiveness may be compromised
Solution Approach 1:
The patent applies local quality by giving different regions of the end disk different sealing properties. The radial sealing element at the outlet opening and the axial sealing element at the drain opening are designed with specific elastic deformability tailored to their respective sealing requirements, ensuring effective sealing at each interface while maintaining overall manufacturing simplicity
3Reliability
If complex three-dimensional sealing designs are used, then sealing performance is improved, but manufacturing expense increases
Solution Approach 1:
The patent segments the sealing function into two distinct but integrated elements: the radial sealing element for the outlet opening and the axial sealing element for the drain opening. This segmentation allows each element to be optimized for its specific sealing task while being manufactured as unified structures, reducing overall complexity and expense compared to a single complex three-dimensional sealing design

AI summary
An oil filter element has first and second end disks between which an annular filter medium is held. The oil to be filtered flows through the filter medium in a direction radial to the longitudinal axis of the oil filter element. The oil filter element has a central channel arranged on the clean side and provided with a central outlet opening in the region of the first end disk. A radial sealing element, formed by an elastically deformable inside circumferential section of the first end disk, is arranged in the region of the outlet opening. In addition, an axial sealing element is arranged on the outside of the first end disk. This axial sealing element is held on the first end disk by retaining elements. An oil filter having such an oil filter element is provided.
