Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices for fluids, such as oil, often have complex designs and inefficient filtering characteristics due to separate filtering media and strainers, leading to difficulties in assembly and reduced filtering efficiency.
Innovation Solution
A filter device with a flat filter element and a parallel strainer, allowing for a compact and simplified construction, where the fluid flows linearly through a pleated filter medium and strainer, enhancing the filtering area and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate filtering media and strainers are used in existing filter devices, then filtering function is achieved, but device complexity increases and assembly becomes difficult
Solution Approach 1:
The patent combines the filter medium and strainer into a single integrated filter element. The filter medium is arranged in a pleated configuration with the strainer positioned parallel to it, creating one unified component that performs both filtering and straining functions simultaneously, thereby reducing device complexity while maintaining filtering reliability
2Productivity
If traditional filter designs are used, then basic filtering is achieved, but filtering area is limited and efficiency is reduced
Solution Approach 1:
The filter medium is configured in a pleated arrangement that extends in multiple directions, effectively increasing the filtering surface area within a compact volume. The pleats create additional filtering surfaces that are stacked in the height direction, thereby enlarging the total filtering area without significantly increasing the footprint of the filter device
3Productivity
If flat filter element with parallel strainer is used, then filtering area is enlarged and efficiency improved, but device design becomes more complex
Solution Approach 1:
The filter element is segmented into distinct functional zones: the pleated filter medium section and the parallel strainer section. This segmentation allows each component to be optimized for its specific function while maintaining a relatively simple overall structure that is easier to manufacture and assemble compared to fully integrated complex designs

AI summary
A filter device for filtering a fluid may include a flat filter element. The flat filer element may extend flat in a longitudinal direction and a transverse direction. The filter element may include at least one pleated filter medium through which a flow path of the fluid leads in a height direction. The at least one filter medium may include a top side and a bottom side facing away from the top side. At least one strainer may be arranged on the top side. The at least one strainer may extend flat parallel to the filter medium and may include a strainer material having multiple passages such that the flow path leads through the strainer in the height direction.
