Transparent Face Mask with Adjustable Fit and Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional face masks impede communication and comfort due to their generic shape, lack of transparency, and inadequate fit, which can lead to irritation and uncertainty about blocking harmful debris and pathogens.
Innovation Solution
A face mask design featuring a transparent shell with inhale and exhale ports, removable filters, and a custom-fit option using image capture and AI-driven measurement for precise facial dimensions, along with additional features like UV-C LEDs, sensors, and an audio system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a generic shape face mask is used, then manufacturing is simple and cost-effective, but the fit and comfort are poor
Solution Approach 1:
The face mask incorporates adjustable straps and elastic components that allow dynamic adaptation to different face shapes and sizes, enabling a single generic mask design to provide customized fit for multiple users while maintaining manufacturing simplicity
Solution Approach 2:
The mask design allows adjustment of key parameters such as strap length, tension, and positioning to optimize fit for different facial dimensions, transforming a static generic design into an adaptable solution that maintains both ease of manufacture and operational comfort
2Reliability
If an opaque face mask is used, then filtration effectiveness is maximized, but communication ability is impaired
Solution Approach 1:
The face mask incorporates transparent windows or panels in specific locations (such as over the mouth area) while maintaining opaque filtration material in other areas, creating local variations in transparency that enable visual communication while preserving filtration effectiveness in the covered regions
3Device complexity
If a simple fabric mask is used, then the design is simple and cost-effective, but protection against pathogens is uncertain
Solution Approach 1:
The face mask combines multiple materials with different properties including filtration layers, sealing materials, and structural components in a composite construction, achieving enhanced pathogen protection while maintaining relative design simplicity through the integration of specialized functional layers
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
The face mask enhances communication and comfort by allowing visual observation of the mouth, providing a snug fit, and ensuring effective filtration and sanitization of air, while also offering customizable fit and advanced features for health monitoring and communication.
Implementation Method 1
at least a portion of the shell having sufficient transparency to provide for visual observation of the mouth of the person
Implementation Method 2
the first filter positioned in the inhale port such that air passing through the inhale port passes through the first filter, the first filter being configured to deactivate a pathogen in the air
Implementation Method 3
the inhale and exhale ports further comprise one or more ultraviolet-C light emitting diodes (UVC LEDs) to sanitize air passing therethrough

AI summary
Masks for being worn by a person are described herein. The masks include a shell configured to cover a nose and a mouth of the person, at least a portion of the shell having sufficient transparency to provide for visual observation of the mouth of the person when the person is wearing the mask. The shell includes an inhale port configured to provide for air to pass from an environment into a cavity defined by the shell when the person wearing the mask inhales and an exhale port configured to provide for air to pass from the cavity to the environment when the person wearing the mask exhales. The masks also include a retaining element coupled to the shell for retaining the mask on the person.
