Folded Metal Mesh Filter Cover for Frame-Free Air Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner filter devices with multi-layer mesh structures require frame members for edge fixation, increasing weight and cost, and existing mesh filters lack effective antiviral and anti-mold purification actions.
Innovation Solution
A filter device with a mesh filter cover formed by folding metal mesh material with a minutely uneven surface, providing antiviral and anti-mold actions, and configured to be self-supporting through fold lines and leg portions, eliminating the need for additional frame members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-layer mesh structure is used for sufficient purification function, then air purification performance is improved, but weight and cost increase due to required frame members
Solution Approach 1:
The patent combines multiple mesh layers into a single integrated mesh structure where the mesh itself forms both the purification layers and the structural support. This eliminates the need for separate frame members while maintaining the multi-layer purification function, thereby reducing weight without compromising air purification performance.
Solution Approach 2:
The mesh structure serves multiple functions simultaneously: it acts as the purification medium, provides structural support, and eliminates the need for separate frame components. This multi-functionality resolves the contradiction by achieving sufficient purification without additional weight from frame members.
2Reliability
If a multi-layer mesh structure is used for sufficient purification function, then air purification performance is improved, but cost increases due to required frame members
Solution Approach 1:
By merging the purification layers and structural support into a single mesh component, the patent reduces the number of parts that need to be manufactured and assembled. This simplification lowers manufacturing costs while maintaining the multi-layer purification function through the integrated mesh design.
Solution Approach 2:
The patent extracts and eliminates the frame member component from the traditional multi-layer mesh structure, retaining only the essential mesh elements that provide purification function. This reduction in components directly lowers manufacturing cost while preserving air purification performance.
3Ease of operation
If frame members are used to fix outer edges of mesh members, then handling is facilitated, but device complexity increases
Solution Approach 1:
The patent merges the structural support function into the mesh itself through self-supporting designs such as folded edges or rigid mesh configurations. This eliminates separate frame members and reduces device complexity while maintaining ease of handling through the inherent structural integrity of the integrated mesh design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances air purification by integrating antiviral and anti-mold actions while simplifying handling and reducing weight and cost by using the metal mesh material itself for structural support, ensuring effective dust collection and purification without additional framing.
Implementation Method 1
on the metal mesh material, a minutely uneven surface is formed... the uneven surface has an antiviral action

AI summary
A filter device 2 is provided with: a filter body 3 equipped with a filtering material 30; and a mesh-like filter cover 5 that is mounted to the filter body 3 in such a manner as to cover at least part of a filtering surface 32 of the filtering material 30. The filter cover 5 is provided with: a purification part 50 which includes multiple layers formed by folding a single sheet of metal mesh material and which has a rectangular shape that is substantially identical to that of the filtering surface 32 in a plan view; and a first leg 51 and a second leg 52 which intersect with the purification part 50 in a side view. The metal mesh material has a finely corrugated surface formed thereon. The entire outer peripheral edge 59 of the filter cover 5 is completely fitted within the filtering surface 32.
