Method for mounting a filter cell for a room air installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling filter cells for ventilation systems are complex and time-consuming due to the high number of individual components and long drying times of liquid PU adhesives, leading to increased production times and costs.
Innovation Solution
A method where passage surfaces are formed in one piece with adjacent side surfaces, and all open housing edges are glued to seal and fix the housing surfaces, reducing the number of components and eliminating the need for rivets or screws, with the adhesive serving both for sealing and stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If six separately formed housing surfaces are riveted together and tightly cast with filter plates using liquid PU adhesive, then the filter cell achieves structural integrity and sealing, but the manufacturing process becomes very complex and production times become long due to large number of individual components and long drying times
Solution Approach 1:
The patent merges multiple separately formed housing surfaces into integrally formed housing surfaces. Specifically, opposite housing surfaces are formed as single integral pieces, eliminating the need for rivets or screws at these joints. This reduces the number of individual components from six separate pieces to fewer integral structures, directly addressing the complexity and production time issues while maintaining structural integrity through the adhesive bonding system.
2Reliability
If six separately formed housing surfaces are assembled with multiple rivets, screws, and adhesive applications, then comprehensive sealing and fixation are achieved, but the number of individual components increases and assembly complexity increases
Solution Approach 1:
The patent combines multiple housing surfaces into integral structures (opposite surfaces as single pieces), reducing the component count. Additionally, the adhesive system is designed to perform multiple functions simultaneously: it seals edges, fixes housing surfaces together, and secures filter plates in place. This multi-functionality reduces the need for separate sealing elements, fasteners, and adhesives, thereby reducing overall device complexity while maintaining comprehensive sealing.
3Reliability
If liquid PU adhesive is used to tightly cast both housing surfaces and filter plates, then comprehensive fixation and sealing are achieved, but drying times become long and production efficiency decreases
Solution Approach 1:
The patent employs preliminary positioning and clamping mechanisms that hold housing surfaces and filter plates in their final positions before adhesive application. This preliminary action ensures proper alignment and contact, allowing the adhesive to cure more efficiently once applied. The clamping system maintains precise positioning during the adhesive drying process, reducing the overall time required by eliminating the need for extended drying periods to ensure proper bonding and alignment.
4Stability of the object's composition
If multiple rivets, screws, and adhesive applications are used to assemble housing surfaces, then structural stability is achieved, but the overall weight of the filter cell increases
Solution Approach 1:
The patent removes heavy mechanical fastening elements such as rivets and screws from the housing assembly process. Instead, it relies on adhesive bonding between integrally formed housing surfaces and between the housing and filter plates. This extraction of heavy components significantly reduces the overall weight of the filter cell while maintaining structural stability through the adhesive bonding system and integral surface design.

AI summary
The invention relates to a method for assembling a filter cell for an air handling system for separating fine dust and/or suspended particles, such as aerosols, toxic dusts, viruses and/or bacteria, from the supply and exhaust air, wherein the filter cell has a box-shaped housing and at least one rectangular filter plate (4) arranged in the housing, wherein the housing has six housing surfaces, two housing surfaces being designed as passage surfaces (1, 13), namely as an inlet surface with at least one, preferably rectangular, inlet opening (6) and as an outlet surface with at least one, preferably rectangular, outlet opening (18), and the four remaining housing surfaces being designed as closed side surfaces connecting the two passage surfaces (1, 13) and forming a flow channel with a rectangular cross-section extending from the inlet surface to the outlet surface.wherein this filter plate (4) has two longitudinal edges (8) aligned parallel to the inlet opening (6) and the corresponding outlet opening (18), and two parallel side edges (3), wherein one longitudinal edge (8) of this filter plate (4) abuts the inside of one passage surface (1), the other longitudinal edge (8) of this filter plate (4) abuts the inside of the other passage surface (13), and the two side edges (3) of this filter plate (4) abut each of a side surface (2) abuts the inside, respectively, and wherein the orientation of this filter plate (4) with respect to the inlet opening (6) and the outlet opening (18) is selected such that the air flowing into the housing through the inlet opening (6) and out of the housing through the corresponding outlet opening (18) flows through this filter plate (4). To specify a method,By means of which a filter cell can be manufactured more easily and quickly, a passage surface (1) is to be formed in one piece with the two side surfaces (2) adjacent to opposite edges, which in the assembled state are in contact with a side edge (3) of each filter plate (4), and with respect to the remaining three housing surfaces, the other passage surface (13) and the two other side surfaces (11) are each formed separately or in one piece with at least one of the remaining housing surfaces, and all open housing edges are glued and thus sealed. The invention also relates to a filter cell for an air handling system.
