Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-dimensional filter structure body with comb-like support structure is used, then the stability and effective area of the filter module are improved, but the device complexity increases
Solution Approach 1:
The support structure is divided into multiple comb-like segments that are arranged parallel to each other. Each segment consists of a base and multiple prongs, creating a modular structure that provides stability while maintaining manufacturability. The segmentation allows the filter sheet to be supported at multiple points without requiring a complex continuous support framework.
Solution Approach 2:
The filter structure transitions from a two-dimensional flat filter sheet to a three-dimensional corrugated structure by inserting the filter sheet between the prongs of the comb-like segments. This dimensional change increases the effective filtering area and structural stability without proportionally increasing the footprint or complexity of the overall device.
2Ease of manufacture
If the filter sheet is fastened using clamping wedges in the corrugation valleys, then the ease of assembly is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The clamping wedges are designed to be inserted into the corrugation valleys where they automatically clamp the filter sheet between the wedge and the comb-like segments. The geometry of the wedges and valleys creates a self-aligning mechanism that guides the filter sheet into the correct position during assembly, reducing the need for high-precision manual positioning while ensuring secure fastening.
3Quantity of substance
If the filter sheet is given a corrugated shape, then the storage capacity and flow distribution are improved, but the device complexity increases
Solution Approach 1:
The filter sheet is formed with a corrugated shape featuring rounded crests and troughs rather than sharp angles. This curvature design increases the volume available for storing separated paint within the corrugation valleys while maintaining a relatively simple overall structure. The rounded geometry also improves flow distribution by reducing turbulence and facilitating uniform paint collection across the filter surface.

AI summary
A filter module for separating impurities from a raw gas stream containing impurities includes at least one three-dimensional filter structure body, through which the raw gas stream can be conducted, and an outer frame for receiving the filter structure body between a raw-side opening and a clean-side opening. The three-dimensional filter structure body includes at least one support structure and a filter layer arranged thereon. The support structure has at least one comb-like segment with a base, from which prongs, which are spaced apart from one another, project jointly in a direction in the longitudinal direction of the base. A laying direction of the filter layer extends in the longitudinal direction of the base. A filter structure body, a kit, and a method for producing a filter structure body are also provided.
