Filter Device Guide Ramp Segmentation for Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern engine compartments of motor vehicles, the increasing scarcity of installation space poses a challenge for filter devices, as traditional guide ramps occupy the entire base region of the filter housing cup, leaving no room for additional components.
Innovation Solution
The guide ramp is redesigned to form a ring segment extending over at most 270°, allowing unused space to be utilized for additional components, and a guide device with multiple positioning elements ensures reliable positioning and flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a guide ramp is formed in an almost closed annular shape to advance the positioning element, then the positioning reliability is improved, but the installation space is occupied and cannot be used for other components
Solution Approach 1:
The guide ramp is segmented into a ring segment shape that extends over at most 270° of the circumference, rather than forming a complete annular shape. This segmentation allows the positioning function to be maintained while freeing up the remaining 90° or more of the base region for additional components such as pumps, valves, or heaters.
2Ease of operation
If the guide ramp occupies the complete base region to ensure proper guidance, then the guidance function is improved, but the versatility for additional components is reduced
Solution Approach 1:
The guide ramp provides partial annular guidance (at most 270°) rather than complete 360° coverage. This partial action is sufficient to ensure proper guidance and positioning of the insert during installation, while the remaining space provides versatility for adding functional components without compromising the guidance function.

AI summary
A filter device comprises a filter housing having a filter housing cup and a filter housing cover. An insert insertable into the filter housing comprises an eccentrically arranged and axially projecting first positioning element configured to engage a positioning contour on a side of the filter housing cup. A guide ramp is provided on the filter housing cup and interacts with a guide device arranged on the insert. The guide ramp is formed of at least one ring segment and extends continuously over at most 270°, and the guide device has a second positioning element. At least one web is arranged on the insert and forms the second positioning element, and the at least one web comprises at least two webs with different axial longitudinal extents arranged one of on the lower end plate of the insert and directly on the insert.
