Gas Detection System with Dynamic Alarm Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal gas monitors only alert users when gas levels reach predetermined hazardous levels, failing to warn of potentially dangerous exposure at lower levels or rapid increases, which can occur before the environment becomes dangerous.
Innovation Solution
A system with sensors and notification devices that alert users based on user-defined minimum notification levels below conventional thresholds and detect changes or rates of change in gas levels, allowing for earlier warnings through adjustable signal frequencies and amplitudes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional monitors only alert at predetermined hazardous levels, then the alarm system is simple and easy to operate, but users are not warned of potential hazards at lower levels or rapid increases
Solution Approach 1:
The system performs preliminary action by alerting users at minimum notification levels that are below conventional predetermined hazardous levels. This early warning allows users to take preventive action before the environment becomes dangerous, improving safety reliability without requiring complex additional hardware
Solution Approach 2:
The system applies dynamics by changing the frequency and/or amplitude of the alarm signal as the measured level approaches the predetermined hazardous level. This dynamic signal adjustment provides progressively stronger warnings while maintaining a relatively simple monitoring system structure
2Loss of time
If the system alerts at lower minimum notification levels, then users receive earlier warnings of potential hazards, but the system requires additional programming and threshold settings
Solution Approach 1:
The system is pre-programmed with minimum notification levels and predetermined hazardous levels, allowing it to automatically provide early warnings without requiring complex real-time configuration. This preliminary setup enables early hazard detection while maintaining ease of operation
Solution Approach 2:
The system changes the parameters of the alarm signal (frequency and/or amplitude) based on the measured level approaching the predetermined hazardous level. This parameter adjustment provides escalating warnings without requiring additional configuration complexity
3Object-generated harmful factors
If the alarm signal frequency and amplitude change as levels approach hazardous thresholds, then users receive more intense warnings, but the notification device becomes more complex
Solution Approach 1:
The notification device applies dynamics by dynamically changing the frequency and/or amplitude of the alarm signal based on the measured gas level approaching the predetermined hazardous level. This dynamic behavior enhances warning effectiveness while using a relatively simple notification device structure

AI summary
Systems and methods thereof for detecting at least one material in an environment prior to the environment reaching levels deemed dangerous by conventional monitors and standards includes at least one sensor adapted to measure a level of the at least one material in the environment surrounding the sensor, at least one notification device adapted to produce a signal, and a memory comprising a preprogrammed level of the at least one material in the environment. The system is programmed with a minimum notification level of the at least one material in the environment that is below the preprogrammed level and is adapted to notify a user with the signal if the level exceeds the minimum notification level. The frequency and/or amplitude of the signal is changed as the level approaches the preprogrammed level.
