Existing liquid filters, such as fuel filters, face challenges in being both efficient and cost-effective, particularly in designing a configuration that allows for efficient water separation and collection without increasing production complexity.
Innovation Solution
A liquid filter design featuring a ring filter insert with a central channel from radially inside to outside, utilizing a one-piece end plate made from plastic, which can be efficiently manufactured using injection molding, and incorporating a water collection chamber for separated water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional multi-piece end plate design is used, then manufacturing precision can be maintained, but production cost and complexity increase
Solution Approach 1:
The end plate is designed as a single integrated component rather than multiple separate pieces. The channel structure is directly formed as part of the end plate body, eliminating the need for separate channel components and reducing assembly steps. This merging of components directly reduces production cost and manufacturing complexity while maintaining the required functional performance.
2Productivity
If a one-piece end plate with integrated channel is used, then production efficiency increases, but manufacturing precision may be compromised
Solution Approach 1:
The manufacturing method is changed from traditional multi-step fabrication to injection molding or die casting, allowing the channel to be formed as a single integrated feature. This parameter change in the manufacturing process enables high production efficiency while maintaining dimensional accuracy through controlled molding parameters and precision tooling design.
3Reliability
If complex water separation structures are added, then water separation efficiency improves, but device complexity increases
Solution Approach 1:
The water separation function is segmented from the main filter structure and implemented through a dedicated collection chamber and drainage channel system. This segmentation allows the water separation function to be optimized independently while maintaining a relatively simple overall structure. The separated water collection and drainage path provides effective water removal without requiring complex additional components.

AI summary
A ring filter insert (3) which can be flowed through radially has, in at least one of its end disks (4, 5), at least one connecting channel (28) which runs radially between interior and exterior of this end disk (4; 5). With such a ring filter insert (3), through a liquid supply channel (14) which is conducted through the central inner space of the ring filter insert (3) which serves as the crude space or clean space, it is possible in construction and rational terms to pass liquid through the at least one connecting channel (28) in at least one of the two end disks (4, 5) of the ring filter insert (3) from the radial inside outward into one of the two crude spaces or clean spaces which are sealed from the other crude space or clean space and communicate only through the filter medium of the ring filter insert (3). The flow through the at least one connecting channel (28) in at least one of the two end disks (4, 5) may also be in the reverse direction from the radial outside inward.
