Wearable DRI Detection Device for Respiratory Infection Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals spending time in climate-controlled environments are more susceptible to respiratory infections due to abrupt changes in temperature and humidity, which can lead to Dewpoint Respiratory Inoculation (DRI), as their airway mucous membranes become compromised during transitions between environments, leaving them vulnerable to airborne pathogens.
Innovation Solution
A wearable device equipped with temperature and humidity sensors that detects abrupt changes in environmental conditions, alerting the user to potential DRI and providing a system to mitigate this risk through alerts and optional humidifying devices, such as a mask or air curtain systems in building vestibules, to maintain a safer transition zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If individuals transition between climate-controlled and outdoor environments, then temperature and humidity regulation is improved, but susceptibility to respiratory infections increases due to abrupt environmental changes
Solution Approach 1:
The system performs preliminary detection of dewpoint conditions and issues warnings before individuals enter high-risk transition zones. By detecting the combination of cold outdoor temperature, high outdoor humidity, and warm indoor temperature, the system alerts users to take preventive measures (such as wearing masks or avoiding transitions) before the harmful condensation process occurs in the airways.
Solution Approach 2:
The system continuously monitors environmental conditions (temperature and humidity) and provides real-time feedback to users about their infection risk. This feedback loop allows individuals to adjust their behavior based on current conditions, such as delaying transitions or using protective equipment when dewpoint conditions are detected.
2Use of energy by moving object
If the body increases mucous production in response to cold air, then thermal energy delivery to nasal passages is improved, but airway moisture balance is disrupted leading to DRI conditions
Solution Approach 1:
The system detects cold, humid outdoor conditions before the individual enters the climate-controlled environment and issues a warning. This preliminary detection allows the individual to take preventive actions (such as using a humidifying mask or avoiding the transition) before the harmful sequence of events—increased mucous production followed by condensation—can occur in the airways.
3Stability of the object's composition
If HVAC systems maintain stable indoor climate, then comfort is improved, but transition zones between indoor and outdoor environments create DRI conditions
Solution Approach 1:
The system introduces an intermediary warning mechanism that alerts individuals to the harmful transition conditions created by the contrast between stable indoor HVAC climate and variable outdoor conditions. The warning system acts as a mediator, allowing individuals to prepare for or avoid the transition zone where DRI conditions occur, thus resolving the conflict between maintaining stable indoor climate and preventing harmful transitions.

AI summary
Systems and methods are provided for detecting a potential for dewpoint respiratory inoculation (DRI). A method includes detecting a change in temperature over time, determining a slope of the change in temperature, comparing the slope of change in temperature with a slope threshold, and if the slope of change in temperature exceeds the slope threshold, then signaling a potential for dewpoint respiratory inoculation. Detection systems can include a personal device with temperature and humidity detectors, a processor for collecting data and identifying conditions that may provoke DRI, and providing a signal to the user.
