Disposable Face Mask with Integrated Color-Changing Pathogen Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting infectious diseases like COVID-19 are hindered by delays in test results and the inability to quickly identify infected individuals, leading to potential continued virus transmission, and face masks are not consistently used or worn correctly, which affects their effectiveness in reducing disease spread.
Innovation Solution
A face mask with integrated used and infectious disease detection mechanisms, including color-changing indicators that differentiate between usage and disease presence, allowing users to determine if the mask has been used too long or if they have an infectious disease, and optionally indicating environmental disease presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional testing methods are used to detect infectious diseases, then test accuracy can be maintained, but there is a delay in receiving test results which allows continued virus transmission
Solution Approach 1:
The mask enables self-testing by the wearer without requiring external laboratory facilities. The infectious disease detection mechanism allows the user to independently determine their infection status immediately, eliminating the time delay associated with professional testing while maintaining reliability through the chemical sensing mechanism.
Solution Approach 2:
The detection mechanism is built into the mask itself in advance, so that testing capability is already present and ready to use at any moment. This preliminary integration of detection functionality eliminates the need to wait for external testing appointments or results.
2Ease of operation
If face masks are made simple and comfortable, then ease of operation improves, but there is no indication of mask usage status or disease presence
Solution Approach 1:
The mask incorporates color-changing indicators that provide visual information about usage status and disease presence. The used indicator mechanism changes color to show when the mask has been worn, and the infectious disease detection mechanism changes color to indicate detected pathogens, thereby compensating for the information loss while maintaining mask simplicity.
Solution Approach 2:
The indicator mechanisms serve as intermediaries that translate internal mask state and detection results into visible visual signals. These color-changing indicators mediate between the mask's functional state and the user's understanding, providing clear information without complicating the mask's basic structure or usage.
3Loss of information
If indicator mechanisms are added to the mask, then information about usage and disease status is provided, but device complexity increases
Solution Approach 1:
The indicator mechanisms are merged with the mask body and filtering layers rather than being separate added components. The used indicator mechanism is integrated into the mask structure, and the infectious disease detection mechanism is combined with the filtering material, thereby reducing overall device complexity while still providing necessary information.
Solution Approach 2:
The mask is designed with multi-functionality, where the same structural elements serve both protective filtering functions and indicator/detection functions. The filtering material simultaneously filters pathogens and contains the detection chemistry, and the mask structure simultaneously protects and indicates usage status, thereby reducing the need for separate dedicated components.

AI summary
A face mask, including a body and at least one securing mechanism operatively attached thereto, and a used indicator mechanism for indicating that the face mask is used and an infectious disease detection mechanism for indicating if the user wearing the face mask has an infectious disease operatively integrated into the body. A method of indicating whether a face mask is used, by a user actuating a used indicator mechanism on the face mask, wearing the face mask, and the used indicator mechanism indicating that the face mask is used. A method of indicating whether a user has an infectious disease, by a user actuating an infectious disease mechanism on a face mask, wearing the face mask, and the infectious disease mechanism indicating that the user has an infectious disease by changing from a first color to a second color.
