Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter mesh structures experience uneven surface wind speeds, leading to high pressure loss and non-uniform consumption of filter materials, which reduces their usage efficiency and adsorption effect.
Innovation Solution
A filter mesh frame comprising a first mesh and a second mesh, where the second mesh includes bar structures with a U-shaped cross section, forming a groove that faces the first mesh, thereby creating a structure with a larger surface area and reduced pressure loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional cylindrical meshes are used in filter mesh structure, then the structure is simple and easy to manufacture, but the surface area is small and pressure loss is high
Solution Approach 1:
The invention transforms the conventional two-dimensional cylindrical mesh into a three-dimensional hollow hemispherical structure with internal partitions. This dimensional change creates multiple internal surfaces for filtration, dramatically increasing the effective surface area from a single cylindrical surface to multiple hemispherical surfaces separated by partition walls, thereby resolving the contradiction between surface area and structural complexity.
Solution Approach 2:
The hollow hemispherical mesh is divided into multiple compartments by internal partition walls. Each partition creates a separate filtration chamber, effectively segmenting the single large surface into multiple smaller surfaces. This segmentation increases the total surface area available for filtration while maintaining a compact overall structure, addressing the surface area requirement without excessive complexity.
2Loss of energy
If conventional cylindrical meshes are used in filter mesh structure, then the structure is simple, but pressure loss is high and filter material cannot be consumed uniformly
Solution Approach 1:
The transition from a compact cylindrical form to an expanded hollow hemispherical form with internal partitions creates longer and more varied airflow paths. Air must traverse multiple compartments separated by partitions, increasing the effective path length and surface area contact time. This dimensional transformation reduces pressure loss by distributing the filtration load across multiple surfaces rather than forcing all air through a single cylindrical surface.
Solution Approach 2:
The partition walls divide the hollow hemisphere into multiple independent compartments, segmenting the airflow into separate streams. Each compartment processes a portion of the total airflow, preventing concentration of pressure drop in a single location. This segmentation ensures more uniform air distribution across the filter material surface, enabling uniform consumption and improving overall usage efficiency.
3Reliability
If conventional filter mesh structure is used, then the adsorption effect of filter material is insufficient, but increasing surface area increases structural complexity
Solution Approach 1:
The hollow hemispherical configuration with internal partitions creates multiple internal surfaces that collectively provide vastly increased adsorption capacity. The three-dimensional arrangement of partition walls generates additional surface areas that are not present in conventional cylindrical designs, allowing more filter material to be effectively utilized for adsorption without simply scaling up the external dimensions.
Solution Approach 2:
The partition walls create multiple separate compartments, each containing filter material that contributes to the overall adsorption effect. This segmentation allows the system to achieve high total adsorption capacity through the cumulative effect of multiple smaller surfaces rather than relying on a single large surface, improving adsorption reliability while maintaining structural manageability.

AI summary
A filter mesh frame is provided. The filter mesh frame includes a first mesh and a second mesh. The first mesh surrounds to form a cylinder with respect to a first pivot direction. The second mesh surrounds the first mesh with respect to a first pivot direction and includes a plurality of bar structures, where the bar structures protrude outward with respect to the first mesh and are disposed parallel to the first pivot direction. A groove parallel to the first pivot direction is formed on one side of each bar structure with respect to the first mesh.
