Innovation Solution
A facemask integrated with a virus detection system that includes virus binding molecules and detection reagents, capable of detecting SARS-CoV-2 through respiratory droplets and aerosol particles, providing a positive indicator signal after exposure, which can be used for early detection and continuous monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RT-PCR tests are used for SARS-CoV-2 detection, then detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential detection function from complex RT-PCR systems by using only virus binding molecules (antibodies) and simple detection reagents on a test region, eliminating the need for complex nucleic acid amplification equipment and procedures while maintaining detection capability
Solution Approach 2:
The facemask with integrated test region uses disposable virus binding molecules and detection reagents that are single-use, eliminating the need for expensive, complex, and reusable laboratory equipment while providing adequate detection for the intended purpose
2Measurement precision
If RT-PCR tests are used for SARS-CoV-2 detection, then detection accuracy is improved, but cost increases
Solution Approach 1:
The patent employs inexpensive disposable components including virus binding molecules printed on the test region and single-use detection reagents, dramatically reducing manufacturing costs compared to expensive RT-PCR reagents and equipment while maintaining sufficient detection accuracy
Solution Approach 2:
The invention extracts only the essential detection components from complex RT-PCR systems, using simple antibody-antigen binding reactions instead of complex nucleic acid amplification, thereby reducing manufacturing costs while preserving core detection functionality
3Measurement precision
If RT-PCR tests are used for SARS-CoV-2 detection, then detection capability is improved, but ease of operation worsens
Solution Approach 1:
The facemask detection system is self-service in that the user simply wears the mask and the detection occurs automatically through respiratory droplet collection on the test region, with results visible without requiring trained personnel or complex operational procedures
Solution Approach 2:
The patent removes the complex operational steps of RT-PCR including sample collection, nucleic acid extraction, amplification, and analysis, retaining only the essential virus binding and detection steps that can be performed by anyone with minimal training
4Loss of time
If facemask with detection system is used, then early detection capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the protective facemask function with the virus detection function by integrating the test region and virus binding molecules directly into the mask structure, allowing simultaneous protection and early detection without requiring separate devices
Solution Approach 2:
The facemask serves multiple functions: it provides respiratory protection, collects viral particles through normal breathing, and performs detection, eliminating the need for separate protective equipment and detection devices
5Duration of action of stationary object
If facemask with detection system is used, then continuous monitoring capability is improved, but ease of operation worsens
Solution Approach 1:
The detection system operates continuously throughout the time the facemask is worn, with the test region continuously exposed to respiratory droplets containing viral particles, enabling real-time monitoring without interrupting normal activities
Solution Approach 2:
The system requires no active user intervention during monitoring - the facemask automatically collects and detects viral particles through normal breathing, making continuous monitoring as easy as wearing the mask
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
Enables early detection of SARS-CoV-2 even at low viral loads and during asymptomatic phases, providing a practical solution for continuous monitoring in public and workplace settings, reducing the risk of transmission by identifying infected individuals before symptoms appear.
Implementation Method 1
The virus detection system includes virus binding molecules in the test region. The virus binding molecules may be antibodies.
Implementation Method 2
The virus detection system may further include one or more detection reagents to provide a signal when the virus is bound to the virus binding particles. The virus detection system may be an enzyme immunoassay (EIA) test.

AI summary
Facemasks with an integrated vims detection system are described. The virus detection system is embedded in or on a acemask worn by an individual susceptible to a viral infection. The individual wears a facemask for protective purposes during work or leisure. If the individual develops a viral infection and begins discharging viral particles from mouth and/or nose, the vims detection system embedded in the facemask retains the virus particles. The virus particles are detected in an immunoassay. The virus particles in the virus detection system embedded in the facemask are detected by avian antibodies. The virus detection system in the facemask is configured to detect one or more viruses, for example, SARS-CoV-2.
