Face Mask Pocket with Side Opening for Mesh Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The face mask with a copper mesh sheet insert, as disclosed in Patent Literature 1, tends to loosen the opening edge at the top due to interference with the nose, allowing unfiltered air to enter the nasal cavity and mouth without passing through the copper mesh.
Innovation Solution
A face mask with a metal mesh insert featuring a face mask body with a pocket that has a side-opened opening, allowing the antibacterial metal mesh component to be easily inserted or removed, and ensuring the opening edge remains closed when worn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening edge is placed at the top of the face mask to allow easy insertion and removal of the metal mesh component, then the ease of operation is improved, but the opening edge loosens due to interference with the nose, causing unfiltered air to enter
Solution Approach 1:
The invention changes the opening direction from the top (vertical dimension) to the side (horizontal dimension). The side-opened opening is formed at the lateral side of the face mask body, allowing the metal mesh component to be inserted and removed from the side rather than from the top. This dimensional change eliminates the interference with the nose while maintaining ease of operation.
Solution Approach 2:
The invention provides a alternative configuration (side-opened opening) that copies the functionality of the top-opened opening (easy access for insertion/removal) without replicating its structural weakness (loosening due to nose interference). The side opening achieves the same operational convenience through a different spatial arrangement.
2Adaptability or versatility
If the top-opened pocket is used to enclose the metal mesh component, then the metal mesh component can be easily inserted and removed, but the opening edge loosens and allows air to bypass the filtration layer
Solution Approach 1:
The invention relocates the opening from the top of the face mask body to the side. The side-opened opening is positioned at the lateral side, allowing the metal mesh component to be inserted and removed horizontally rather than vertically from the top. This eliminates the structural weakness of the top opening edge loosening while preserving the adaptability of removing the metal mesh component.
Solution Approach 2:
The invention extracts the opening function from the top edge of the face mask body and relocates it to the side edge. This separation allows the main top edge to maintain its structural integrity and proper fit against the face, while the side opening provides the necessary access for component removal without compromising filtration effectiveness.
3Device complexity
If the opening edge is positioned at the top for metal mesh access, then the device complexity is reduced, but the structural stability deteriorates due to loosening from nose interference
Solution Approach 1:
The invention maintains the simplicity of the pocket structure by using a single opening, but relocates it from the top to the side. This positional change in another dimension (from vertical to horizontal access) eliminates the structural instability caused by nose interference while preserving the overall simplicity of the design.
Solution Approach 2:
The invention applies the opening function locally at the side of the face mask body rather than at the top. This localized placement at the lateral side allows the opening edge to remain stable during wear, as it is not subjected to the same mechanical interference from the nose that affects the top opening edge.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the antibacterial and antiviral effects of the face mask by ensuring that all inhaled air passes through the metal mesh component, thereby improving filtration efficiency.
Implementation Method 1
an antibacterial metal mesh component attachable to the face mask body. The face mask body has a pocket into which the metal mesh component is enclosed, and the pocket has a side-opened opening, through which the metal mesh component can be inserted or taken out.

AI summary
Provided is a face mask with metal mesh insert (1) that includes a face mask body (2) structured to cover a human mouth and around; a mask cord (3) provided to each of both lateral sides of the face mask body (2); and an antibacterial metal mesh component (4) attachable to the face mask body. The face mask body (2) has a pocket (5) into which the metal mesh component (4) is enclosed. The pocket (5) has a side-opened opening (5b), through which the metal mesh component (4) can be inserted or taken out. The side-opened opening (5b) is likely to close when the face mask with metal mesh insert (1) is worn by a human.
