Wearable Air Quality Module for Hazardous Gas Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient air in certain areas often contains harmful gases and particulates, making it difficult for individuals to determine when to wear personal protection equipment (PPE) such as masks, as they may not be aware of the presence of harmful substances.
Innovation Solution
A wearable air quality module with sensors, such as PM 2.5 and gas sensors, communicates data to a mobile device, which processes the information to alert the user when harmful substances are detected and provides guidance on necessary PPE and locations to obtain it, while also transmitting data to a cloud server for further analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wearable air quality module with sensors is used to detect harmful substances, then user safety and health protection is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (PM 2.5 sensor, gas sensor), microcontroller, wireless communication module, and alert mechanism into a single integrated wearable air quality module. This merging approach maintains comprehensive detection capabilities while consolidating components into one wearable device that users can carry conveniently.
Solution Approach 2:
The wearable module performs multiple functions: detecting particulate matter (PM 2.5), detecting harmful gases, communicating data wirelessly to mobile devices, and providing visual/audio alerts. This multi-functionality ensures comprehensive air quality monitoring and user protection within a single device.
2Ease of operation
If real-time air quality monitoring and PPE guidance is provided through mobile device, then ease of operation is improved, but loss of time for data processing and communication increases
Solution Approach 1:
The system pre-processes sensor data on the mobile device and maintains a lookup table of PPE recommendations for different air quality conditions. When harmful substances are detected, the mobile device can quickly retrieve and display appropriate PPE guidance without requiring complex real-time analysis, thus reducing processing time.
Solution Approach 2:
The system provides immediate visual and audio feedback through the mobile device when harmful substances are detected. The mobile device continuously receives data from the wearable module and provides real-time alerts and PPE recommendations, creating a fast feedback loop that minimizes the perceived delay for users.
3Measurement precision
If comprehensive air quality data is collected and transmitted to cloud server, then air quality monitoring accuracy is improved, but use of energy increases
Solution Approach 1:
The wearable module and mobile device transmit air quality data to the cloud server at periodic intervals rather than continuously. This periodic transmission approach maintains comprehensive data collection for accurate air quality monitoring while significantly reducing the energy consumption associated with constant wireless communication.

AI summary
Embodiments relate generally to systems and methods for detecting harmful substances in the ambient air around a user, such as particulate matter and toxic gases, and communicating this information to the user and other interested parties. In certain areas, the ambient air in a city or area may sometimes contain harmful gases and/or particulates. People may be encouraged to wear and/or carry certain PPE devices, such as masks, to protect themselves from the harmful substances in the air. However, a user may not always know when they are breathing in a harmful substance and should be wearing a mask. Also, a method may comprise activating an alarm to user to when environment is polluted, and alerting the user when to wear the respiratory mask. Additionally, a system may provide information on where a user may be able to obtain a mask or other PPE, based on the detected harmful substance.
