Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are disposed underground in concrete in advance, then the sensor system is stable and protected, but it becomes impossible to replace or inspect the sensors
Solution Approach 1:
The sensor system is divided into modular components: sensor modules, communication modules, and power sources. Each sensor module can be independently replaced without affecting other components, enabling maintenance while maintaining system stability during operation.
Solution Approach 2:
The system transitions from a static embedded sensor configuration to a dynamic modular architecture where components can be dynamically replaced and reconfigured. Sensor modules are designed to be interchangeable, allowing inspection and replacement while the system remains operational.
2Device complexity
If a single integrated power source is used for the entire sensor device, then the device structure is simple, but it becomes impossible to maintain the device when the power source fails
Solution Approach 1:
The power supply system is segmented into multiple independent power sources, each dedicated to specific modules (sensor module power source, communication module power source). This modular power architecture allows individual power sources to be replaced without affecting other system components.
Solution Approach 2:
Different power sources are assigned to different functional modules based on their specific power requirements and operational characteristics. Each module has its own power source optimized for its function, enabling localized maintenance and replacement.
3Reliability
If conventional gas detection systems are installed underground, then they provide gas leak detection capability, but they cannot monitor gas leaks at all times due to inability to inspect or replace sensors
Solution Approach 1:
The system performs preliminary actions by implementing a modular architecture with replaceable sensor modules and independent power sources before failures occur. This design enables proactive maintenance and ensures continuous operational capability by allowing quick replacement of failed components.
Solution Approach 2:
The system maintains continuous gas leak monitoring capability through modular redundancy. When one sensor module fails, it can be replaced without interrupting overall system operation, ensuring uninterrupted detection coverage and continuous useful action.

AI summary
A gas monitoring system includes at least one sensor device that detects gas and outputs a detection result; and a gateway that receives the detection result. The at least one sensor device includes a sensor module having a gas sensor that detects gas; an analog-to-digital (A/D) converter that processes the detection result outputted from the gas sensor; a communication module that communicates with the sensor module and transmits information processed by the A/D converter exteriorly of the at least one sensor device; a power source that is an electric power source of the sensor module; and a power source that is an electric power source of the communication module.
