Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional masks are worn for long continuous hours, then protection against airborne droplets is provided, but skin abrasions and discomfort occur due to inadequate fit
Solution Approach 1:
The mask system is divided into multiple functional components: a rigid outer shield for structural integrity and droplet blocking, a flexible inner seal for comfort and fit, and separate sensor/communication modules. This segmentation allows each component to be optimized for its specific function while reducing overall discomfort.
Solution Approach 2:
Different regions of the mask have different properties: the outer shield is rigid and impermeable for maximum protection, while the inner seal is soft and flexible for comfort against the skin. The communication unit and sensors are localized to specific areas that do not interfere with the sealing surfaces.
2Measurement precision
If smart communication technologies are added to detect viral contamination, then detection capability is improved, but device complexity increases
Solution Approach 1:
The microcontroller unit serves multiple functions: it controls the sensors for viral detection, manages the communication protocols for data transmission, controls the LED indicators for status display, and processes sensor data. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The communication unit acts as an intermediary between the sensors and the external monitoring system. It collects data from the sensors, formats it according to communication protocols, and transmits it wirelessly, thereby simplifying the overall system architecture by providing a single interface for data output.
3Illumination intensity
If transparent acrylic shield is used, then visibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The mask is segmented into the transparent acrylic shield as a separate, pre-manufactured component with standardized dimensions. This allows the shield to be manufactured independently with high precision using specialized equipment, while the other components can be attached to it during assembly.
Solution Approach 2:
The design specifies particular parameters for the acrylic shield such as thickness, transparency level, and curvature radius. By standardizing these parameters, the manufacturing process can be optimized for mass production while maintaining the required visibility and protective properties.

AI summary
A smart mask including sensors, an RFID tag, a microcontroller and a communications device communicates by a near field communications protocol with a WiFi access point, which sends sensor readings, a location, and an identification to a cloud based smart mask monitoring application, which registers the smart mask, and stores the identification. The sensor readings are analyzed by the cloud based smart mask monitoring application to determine when a person wearing the smart mask may be contaminated by COVID-19. A neighborhood analysis is conducted to identify other smart mask wearers who may have come in contact with the contaminated person, and the other smart mask wearers are notified. Instructions are sent to the microcontroller to activate LEDs which indicate whether the health status of the person is normal, is possibly infected or is contaminated. A smart phone including a native smart mask monitoring application may display the health status.
