Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature monitoring is added to gas detectors, then safety monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent combines temperature sensing, humidity sensing, gas detection, and wireless communication functions into a single integrated wearable device. The temperature sensor and humidity sensor are incorporated alongside existing gas detection components, creating a multi-functional safety monitor that reduces overall system complexity compared to separate devices.
Solution Approach 2:
The wearable device is designed to perform multiple safety functions simultaneously: detecting hazardous gases, monitoring ambient temperature, measuring body temperature, detecting humidity levels, and providing wireless alerts. This multi-functional approach consolidates what would traditionally require multiple separate devices into one universal safety platform.
2Measurement precision
If multiple sensors and alert mechanisms are integrated, then safety monitoring accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The device automatically monitors multiple parameters (gas levels, temperature, humidity) and autonomously determines when alert conditions are met based on pre-programmed thresholds. The system self-manages data collection from multiple sensors, threshold comparison, and alert activation without requiring user intervention or complex configuration, maintaining ease of operation despite enhanced monitoring capabilities.
Solution Approach 2:
Alert thresholds for temperature, humidity, and gas levels are pre-configured in the device before deployment. The system is ready to immediately compare sensor readings against these predetermined thresholds and trigger alerts without requiring real-time user input or complex decision-making, simplifying operation while maintaining high monitoring accuracy.
3Loss of time
If wireless alert communication is implemented, then safety response time is improved, but energy consumption increases
Solution Approach 1:
The wireless communication system operates periodically rather than continuously, transmitting data and alerts at scheduled intervals or only when threshold violations occur. This periodic transmission approach minimizes energy consumption by keeping the wireless module in low-power states between transmissions, while still ensuring timely safety alerts when hazardous conditions are detected.
Solution Approach 2:
The system implements feedback mechanisms where alert transmissions are triggered by specific conditions (threshold exceedances) rather than continuous operation. The device monitors sensor inputs, compares them against thresholds, and only activates wireless communication when feedback from the sensors indicates hazardous conditions, optimizing energy usage based on actual environmental conditions.

AI summary
A gas detector includes environmental condition detection circuitry that includes one or more sensors, data processing circuitry, and wireless communication circuitry. The gas detector is configured to be carried by a user. The environmental condition detection circuitry detects the presence or lack of presence of a particular gas in a vicinity of the gas detector and further detects a temperature in the vicinity of the gas detector and communicates detection data to the data processing circuitry. In response to detection of a hazardous temperature condition, the data processing circuitry of the gas detector provides an alert notification to the user carrying the gas detector. Also disclosed is an alert system including multiple gas detectors in which a first gas detector communicates an alert to a second gas detector via wireless communication, and in response, the second gas detector transmits the alert to another gas detector or device via wireless communication.
