Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid treatment devices face limitations in efficiency and versatility, particularly in performing different treatment steps such as separation of solids, liquids, or combinations thereof, depending on intended use.
Innovation Solution
A fluid treatment device with first and second tubular elements forming a flow chamber, where the first element has a uniform or non-uniform contour and the second element has a complementary contour, allowing for tailored treatment steps and flow behavior, with the selection of contour determining the treatment properties and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional filter device with single or multiple filter cartridges is used, then basic filtration function is achieved, but treatment efficiency and versatility for different separation requirements (solids-liquid, liquid-liquid) are limited
Solution Approach 1:
The device is divided into multiple treatment chambers (first treatment chamber with first filter element, second treatment chamber with second filter element) that can be arranged in series. Each chamber performs a specific treatment step, allowing the system to handle different separation requirements (solids-liquid separation in first chamber, liquid-liquid separation in second chamber) independently and efficiently
Solution Approach 2:
The device is designed to perform multiple treatment functions within a single integrated system. By combining different filter elements (depth filter, surface filter, coalescing filter) in different chambers, the device can accomplish both solids-liquid separation and liquid-liquid separation, making it versatile for various applications without requiring multiple separate devices
2Ease of manufacture
If filter elements with fixed contours are used, then manufacturing simplicity is maintained, but flow distribution uniformity and treatment performance are compromised
Solution Approach 1:
The filter elements are designed with non-uniform contours that create different local flow characteristics. The contour is specifically shaped to distribute flow more uniformly across the filter surface in critical areas, improving treatment performance without requiring complex manufacturing processes throughout the entire element
3Device complexity
If a single chamber design is used, then device complexity is reduced, but the ability to perform sequential treatment steps (solids separation followed by liquid separation) is limited
Solution Approach 1:
The second treatment chamber is positioned inside or adjacent to the first treatment chamber, with the first filter element extending into the second chamber. This nested arrangement allows sequential treatment steps to occur in a compact configuration, maintaining relatively simple device complexity while enabling sophisticated multi-stage treatment functionality

AI summary
A device for treating fluid, in particular a filter device, has first and second tubular elements (12), (14) forming an element assembly (10). One element (14) is accommodated in the other element (12) forming a flow chamber (33) between the two elements (12, 14), with a first element (12) arranged in the direction of the inflow side (29) of a fluid to be treated and a second element (14) arranged in the direction of the outflow side (31) of the treated fluid in the element assembly (10). During the fluid treatment, the flow is routed through both elements (12, 14) in succession from the direction of the inflow side (29) towards the outflow side (31). In a joint viewing direction (P), the first element (12) facing the inflow side (29) at least partially has a uniform or non-uniform contour and the second element (14) facing the outflow side (31) at least partially has a non-uniform or uniform contour.
