Filtration Module Bracketing Profile for Uniform Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filtration modules face challenges with labor-intensive assembly, uneven contact pressure distribution, and difficulty in achieving secure engagement due to the use of multiple clamps or snap-fit connectors, which complicates production and increases costs.
Innovation Solution
A filtration module design featuring a resilient bracketing profile that clasps plates along their side surfaces, ensuring uniform contact pressure and secure engagement with a single pressing means, utilizing a curved base and inwardly curved lateral brackets for pre-tensioning and a common peripheral edge seal for simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple clamps are used as pressing means, then secure engagement and contact pressure can be achieved, but assembly becomes labor-intensive and production time increases
Solution Approach 1:
Multiple separate clamps are merged into a single integrated bracketing profile that spans across both plates. This single profile incorporates multiple contact points and pressing zones, combining the functions of what would otherwise require multiple separate clamping devices, thereby reducing assembly complexity and time while maintaining secure engagement.
Solution Approach 2:
The bracketing profile is designed with segmented functional zones along its length, with different sections providing varying degrees of contact pressure and engagement. This segmentation allows a single component to deliver differentiated pressing forces at multiple locations, achieving the effect of multiple clamps while using only one physical component.
2Manufacturing precision
If multiple snap-fit connectors are used to achieve even contact pressure, then uniform pressing force can be obtained, but device complexity and manufacturing cost increase
Solution Approach 1:
Multiple snap-fit connectors are merged into a single continuous bracketing profile with integrated pressing features. The profile incorporates multiple contact surfaces and elastic elements along its length, combining the functions of multiple discrete snap-fit connectors into one unified component, thereby reducing part count while maintaining uniform contact pressure distribution.
Solution Approach 2:
The bracketing profile features locally differentiated properties along its length, with varying thickness, material density, or geometric configuration at different sections to provide optimized contact pressure distribution. This allows a single component to deliver non-uniform local characteristics (different pressing forces at different locations) while maintaining overall structural integrity and simplicity.
3Device complexity
If a single pressing means is used to simplify the device, then fewer parts and lower cost are achieved, but uniform contact pressure distribution becomes difficult
Solution Approach 1:
The bracketing profile incorporates curved and contoured surfaces that conform to the geometry of the plates and filter elements. These curved features distribute contact pressure more evenly across the interface, allowing a single pressing component to achieve uniform pressure distribution that would otherwise require multiple precisely positioned clamps or connectors.
Solution Approach 2:
The bracketing profile utilizes changes in material parameters (such as elastic modulus, hardness, or damping characteristics) and geometric parameters (thickness, cross-sectional area, or contour shape) along its length to modulate the contact pressure distribution. This allows a single component to adapt its pressing characteristics at different locations, achieving uniform pressure distribution without requiring multiple separate pressing means.

Implementation Method 1
The bracketing profile (3) is made of resilient material and has a base (13) which is curved inwards transversely to the longitudinal direction (14) of the plates (4, 5). The base (13) is delimited in the longitudinal direction (14) by lateral brackets (16, 17), which are curved inwards at their free ends (18, 19).

AI summary
A filtration module (1) has a filter unit (2) with at least one filter element (6) arranged between first and second plates (4, 5). The filter element (6) has at least one layer of filter material (9, 10) sealed off at a periphery by an edge seal (12). The plates (4, 5) are pressed against each other by a resilient bracketing profile (3) that engages around the plates (4, 5) at their opposite side surfaces (21, 22, 23, 24). The bracketing profile (3) has a base (13) that curves inward transversely to the longitudinal direction (14) of the plates (4, 5) and that is delimited by lateral brackets (16, 17) that are bent inward at their free ends (18, 19) to engage laterally around a surface (20) of the filter element (6) facing away from the base (13). A method also is provided for producing a filtration module.
