Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas monitoring is performed without automated response systems, then the system complexity is low, but the reliability of gas leakage prevention is insufficient
Solution Approach 1:
The system pre-configures multiple response strategies (natural ventilation, forced ventilation, emergency shutdown) and automatically selects the appropriate strategy based on real-time gas concentration data. This preliminary preparation of response options enables rapid automated reaction to gas leaks without requiring complex real-time decision-making logic, thereby improving reliability while controlling system complexity
Solution Approach 2:
The system continuously monitors gas concentration and compares it against threshold values, then automatically adjusts ventilation strategies based on the feedback from concentration measurements. This closed-loop feedback mechanism ensures reliable gas leakage prevention by dynamically responding to actual conditions without requiring overly complex manual intervention systems
2Loss of time
If manual gas leakage response is used, then the device complexity is low, but the loss of time in responding to gas leaks is significant
Solution Approach 1:
The system pre-configures multiple response strategies (natural ventilation, forced ventilation, emergency shutdown) and automatically selects the appropriate strategy based on real-time gas concentration data. This preliminary preparation of response options enables rapid automated reaction to gas leaks without requiring complex real-time decision-making logic, thereby improving reliability while controlling system complexity
Solution Approach 2:
The system automatically monitors gas concentrations and executes appropriate response strategies without requiring human intervention. The automated system serves itself by detecting gas leaks and immediately implementing pre-configured mitigation measures, dramatically reducing response time while maintaining manageable automation levels through rule-based decision logic
3Loss of information
If generic gas alarm notifications are sent, then the ease of operation is high, but the loss of information about specific leakage types is significant
Solution Approach 1:
The system analyzes the temporal pattern of gas concentration changes to identify specific leakage characteristics (continuous vs. intermittent, rate of increase) and sends customized notification messages tailored to each leakage type. This localized differentiation of information based on specific leakage characteristics provides detailed leakage type information without requiring complex user interpretation, as each notification is optimized for its specific scenario
4Reliability
If fan operation strategies are implemented for gas removal, then the effectiveness of gas leakage treatment is improved, but the use of energy increases
Solution Approach 1:
The system dynamically adjusts fan operation based on real-time gas concentration measurements and leakage characteristics. Fans operate at variable speeds and durations tailored to the specific leakage scenario, providing effective gas removal when needed while minimizing energy consumption during normal operation or minor fluctuations. This dynamic control optimizes the balance between treatment effectiveness and energy usage

AI summary
Disclosed is a determination and alarm method and a determination and alarm Internet of Things (IoT) system for a gas leakage of smart gas. The determination and alarm method comprises obtaining gas monitoring data based on a data acquisition instruction, and determining whether the gas leakage occurs; in response to occurrence of the gas leakage, generating a control instruction based on a fan operation strategy to control operation of a fan, and obtaining the gas monitoring data under the fan operation strategy; generating a notification instruction based on the gas monitoring data and an operating strategy of an indicator light, and controlling the indicator light to issue an alarm notification based on the notification instruction; and determining a type of the gas leakage by processing the fan operation strategy, the operating condition of the indicator light, and the gas monitoring data of at least one time point.
