Breathing Mask Continuous Cover Layer and Elastic Side Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable breathing masks are complex to produce and require multiple materials and sections, making them costly and difficult to manufacture in large quantities while maintaining good functional properties and comfort.
Innovation Solution
A breathing mask design featuring a continuous nonwoven cover layer over the middle and side sections, with elastic restoring layers only on the side sections, allowing for adjustable fit and easy production as an endless web, reducing material usage and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate sections and materials are combined to create breathing masks with good functional properties, then wearing comfort and protection are improved, but manufacturing complexity and production time increase
Solution Approach 1:
The patent merges the central section and side sections into a single continuous nonwoven cover layer, eliminating the need to combine multiple separate components. This single-layer construction maintains functional integrity while dramatically simplifying manufacturing processes and reducing production time.
Solution Approach 2:
The continuous nonwoven cover layer serves multiple functions simultaneously: it provides the main body structure, ensures particle filtration across the entire mask surface, and eliminates the need for separate sealing components. This multi-functionality reduces manufacturing complexity while maintaining protective effectiveness.
2Reliability
If multiple materials and sections are used to ensure good functional properties, then protection and comfort are improved, but material costs and production expenses increase
Solution Approach 1:
The patent combines multiple functional requirements into a single nonwoven cover layer that provides both structural integrity and particle filtration across the entire mask surface, eliminating the need for separate filtration components and reducing overall material consumption.
Solution Approach 2:
The use of a homogeneous nonwoven material throughout the entire mask structure simplifies material selection and procurement while ensuring consistent protective properties across all areas of the mask, reducing the need for multiple specialized materials.
3Reliability
If separate sections are joined together to create breathing masks, then functional properties are improved, but pronounced seams are created that reduce wearing comfort
Solution Approach 1:
The patent eliminates seams by merging the central and side sections into a single continuous nonwoven cover layer. This seamless construction removes uncomfortable joints and edges that would otherwise be present at the interfaces between separate components, significantly improving wearing comfort.
4Reliability
If elastic bands are attached to secure the mask to ears, then the mask stays in place, but the structure becomes more complex and harder to manufacture
Solution Approach 1:
The patent merges the side sections directly into the continuous nonwoven cover layer, creating an integrated structure that eliminates the need for separate elastic bands and attachment components. This integration maintains mask security while dramatically simplifying the overall structure and manufacturing process.

AI summary
The invention relates to a breathing mask (3) with a central section (8) and with a first side section (9a) and a second side section (9b), which adjoin the central section (8) opposite each other along a transverse direction (Q), wherein a first cover layer (2) extends continuously along the central section (8) and the two side sections (9a, 9b). According to the invention, an elastic recovery layer with a first recovery layer section (4a) and a second recovery layer section (4b) is provided only at the two side sections (9a, 9b) and is connected there to the first cover layer (2). The invention also relates to a method for manufacturing the breathing mask.
