Solution Overview
Problem
Residents are often unaware of how to prevent and respond to gas leaks in indoor gas systems, leading to potential personal and property losses due to inadequate solutions.
Innovation Solution
An alarm-based prevention and control method for smart gas systems that includes obtaining gas monitoring data, determining gas leaks, generating control instructions for fans to remove leaking gas, and using indicator lights to alert users through dynamic flicker patterns and frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas monitoring data is obtained and fan operation strategy is applied to remove leaking gas, then the effectiveness of gas leakage control is improved, but the response time and system complexity increase
Solution Approach 1:
The system pre-establishes fan operation strategies and notification instructions before gas leakage occurs. When leakage is detected, the pre-prepared control instructions are immediately executed, eliminating the need for real-time decision-making and reducing response time while maintaining effective gas leakage control.
Solution Approach 2:
The system automatically generates control instructions for fan operation and notification instructions for indicator lights based on detected gas leakage data, without requiring human intervention. This automated self-service approach reduces response time while ensuring reliable and consistent gas leakage control effectiveness.
2Loss of information
If indicator light is used to provide alarm notifications with different flicker states and frequencies, then the information transmission to users is improved, but the device complexity increases
Solution Approach 1:
The indicator light uses different flicker states and frequencies to represent different types of gas leakage and notification priorities. This visual encoding method transmits multiple types of information through a single indicator light device, improving information transmission without requiring multiple separate notification devices.
Solution Approach 2:
The indicator light employs periodic flickering at different frequencies to convey different information about gas leakage situations. This periodic action allows the system to transmit detailed information about leakage severity and type using a simple on/off light mechanism, avoiding the need for complex display systems.
3Reliability
If fan operation strategy is applied to remove leaking gas, then the safety response effectiveness is improved, but the energy consumption increases
Solution Approach 1:
The system applies fan operation strategies selectively based on the detected gas leakage situation. Fan operation is activated only when gas leakage is detected and the concentration exceeds thresholds, rather than running continuously. This partial action approach maintains high safety response effectiveness while significantly reducing overall energy consumption compared to continuous operation.
