Helmet Facemask Attachment Segmentation for Aerosol Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmets with faceguards do not provide protection against airborne or aerosol particles and pathogens, posing a risk during sports or athletic activities.
Innovation Solution
A facemask design for helmets that includes multiple fabric members connected via seams and fasteners, forming an upper and lower edge, with attachment members to secure the facemask to the faceguard, providing a protective barrier against particles and aerosols while allowing for comfort and visibility.

Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional helmets with faceguards are used, then the helmet provides basic structural protection, but it does not provide protection against airborne or aerosol particles and pathogens
Solution Approach 1:
The facemask is divided into multiple fabric members (first fabric member, second fabric member, third fabric member) connected via seams, with separate attachment members distributed along the facemask. This segmentation allows the protective function to be added without redesigning the entire helmet structure, thus improving protection against particles while maintaining manageable device complexity.
Solution Approach 2:
The facemask is designed as a multi-functional component that attaches to the existing helmet and faceguard structure. It provides both particle protection and integrates with the existing helmet system through multiple attachment members (end connectors and intermediate connectors), making it a universal solution that enhances existing equipment without requiring complete redesign.
2Reliability
If multiple attachment members are added to secure the facemask to the faceguard, then the protective barrier is enhanced, but the device complexity increases
Solution Approach 1:
The attachment system is segmented into end connectors at the extremes and intermediate connectors distributed along the facemask. This segmentation provides multiple secure attachment points, enhancing reliability of the protective barrier while organizing the complexity into a systematic pattern that can be manufactured and assembled efficiently.
Solution Approach 2:
Multiple attachment members (end connectors and intermediate connectors) are combined into a unified facemask assembly that attaches to the faceguard as a single integrated unit. This merging approach provides enhanced secure attachment while presenting a single protective barrier component, thus managing the complexity through functional integration.

AI summary
A facemask assembly for a helmet is provided with a facemask. The facemask has an upper edge to be adjacent to a nose of a user and a lower edge to be adjacent to a chin of the user when the facemask is connected to the helmet. A first end attachment member is connected to a first end region of the facemask to attach to a faceguard. A second end attachment member is connected to a second end region of the facemask to attach to the faceguard. A series of intermediate attachment members are spaced apart from one another and connected to the facemask between the first and second end regions, with each intermediate attachment member to attach to the faceguard. A method of forming the facemask is also provided.
