Recessed-Handle Filter Element for Compact High-Capacity Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter elements for vehicles are cumbersome to handle due to their size and weight, and they require efficient space utilization for filtration performance.
Innovation Solution
A filter element with a recess in one side and a handle element spanning the recess, connected to the filter medium body, and a circumferential seal on the opposite side, allowing for easier handling and improved space utilization.

Engineering Contradiction Analysis
1Productivity
If the filter element is made large to improve filtration performance, then the filtration performance is improved, but the handling becomes more difficult due to size and weight
Solution Approach 1:
The filter element is divided into functional segments: the filter medium body for filtration and the handle element for handling. The handle element is a separate component that can be attached to or integrated with the filter medium body, allowing the handling function to be separated from the filtration function. This segmentation enables the filter element to maintain large dimensions for high filtration performance while incorporating a dedicated handle structure that improves grip and maneuverability during installation and removal.
2Volume of stationary object
If the filter element size is increased to maximize space utilization for filtration, then the filtration capacity is improved, but the ease of manipulation during exchange is reduced
Solution Approach 1:
The handle element extends in a direction perpendicular to the main filtration surface, adding a new dimensional aspect to the filter element design. This vertical extension allows the handle to protrude from the filter medium body, providing a gripping surface that does not interfere with the horizontal space requirements of the filtration area. The handle can be positioned to extend upward or outward, enabling operators to grasp and maneuver the large filter element without requiring additional horizontal clearance beyond what is already allocated for the filter housing.
3Volume of stationary object
If the filter element is designed with a compact structure to reduce installation space, then the space utilization is improved, but the handling becomes more difficult
Solution Approach 1:
The handle element is nested within or integrated with the filter medium body structure. The handle can be positioned within recesses or cavities of the filter medium body, or the filter medium body can be folded or configured to accommodate the handle element. This nesting approach allows the handle to be incorporated into the overall filter element volume without significantly increasing the external dimensions. The handle remains accessible for gripping while maintaining a compact overall form factor that fits efficiently within the filter housing space.

AI summary
A filter element has a filter medium body provided with an inflow side and an outflow side, wherein the filter element may be flowed through in a height direction from the inflow side to the outflow side. The filter medium body has at least one recess at the inflow side or at the outflow side and has a reduced height in the recess. A handle element is arranged in the recess and connected to the filter medium body. A circumferential seal is connected to the filter medium body at the outflow side facing away from the inflow side provided with the recess or at the inflow side facing away from the outflow side provided with the recess. The handle element spans at least a central region of the recess. A filter device has the filter element arranged in a filter housing provided with a housing pot and a housing cover.
