Pleated Filter Housing Assembly for Airtight Leak Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pleated filter housings are complex, time-consuming to assemble, and prone to air leaks due to numerous connections between separate parts, compromising air tightness.
Innovation Solution
The housing is constructed with integrally made front, back, top, and bottom walls, which are mechanically fixed or clamped together, eliminating the need for separate assembly and reducing leakage risks through form-fitting connections and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the housing is made from multiple separate parts connected together, then the housing can be manufactured and assembled, but the assembly becomes time-consuming and costly, and air tightness cannot be guaranteed
Solution Approach 1:
The patent merges multiple separate housing parts (front wall, back wall, top wall, bottom wall, and support elements) into a single integral housing structure. This eliminates the need for assembly operations, reducing assembly time and cost while ensuring air tightness by removing connection interfaces where leaks could occur.
2Ease of manufacture
If the housing is made from multiple separate parts connected together, then the housing can be manufactured and assembled, but the risk of air leaking past the filter increases
Solution Approach 1:
The patent merges multiple separate housing parts into a single integral structure, eliminating connection interfaces between parts. This ensures air tightness by removing potential leakage paths at connection points, while the single-piece construction maintains manufacturability through appropriate material selection and forming processes.
3Loss of time
If each wall is made as an integral part, then assembly is simplified and leakage risk is reduced, but the structural connection between walls must be ensured
Solution Approach 1:
The patent merges all wall components into a single integral structure, eliminating assembly operations entirely. The structural integrity is ensured through the monolithic construction itself, where all walls are formed as one continuous piece, providing inherent structural connection without requiring separate fastening mechanisms.

AI summary
The invention relates to a housing for a pleated filter, comprising a front wall having at least one inflow opening, a back wall arranged at a distance therebehind and having at least one outflow opening, and a top wall and a bottom wall which each extend between the front and back walls, wherein each of the front, back, top and bottom walls is integrally made. The top wall and the bottom wall may be mechanically fixed to each of the front and back walls, e.g. by clicking or clamping. The invention also relates to a method for manufacturing such a housing for a pleated filter.
