Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed gas-quality monitoring station is used, then the monitoring location is stable, but it cannot detect suspended particle concentration in the current environment due to unstable gas flow and variable wind direction
Solution Approach 1:
The patent transitions from a fixed monitoring station to a mobile monitoring device that can be moved to different locations. The mobile device includes a gas sensor, processor, and communication module, enabling real-time detection of suspended particles at various positions to adapt to changing environmental conditions and provide current location-specific air quality data
2Measurement precision
If general gas-quality monitoring stations are deployed, then air quality can be monitored at fixed points, but real-time detection and warning capabilities are insufficient due to unstable gas flow
Solution Approach 1:
The mobile monitoring device incorporates real-time detection and feedback mechanisms. The gas sensor continuously monitors suspended particle concentrations, the processor analyzes the data in real-time, and the system provides immediate warnings through the communication module when hazardous levels are detected, enabling timely response to air quality changes
Solution Approach 2:
The patent replaces traditional fixed mechanical monitoring infrastructure with a mobile electronic monitoring system. The mobile device uses electronic sensors, processors, and wireless communication to achieve real-time detection and warning capabilities, substituting the static mechanical monitoring station with a dynamic electronic system that can rapidly respond to environmental changes
3Loss of information
If indoor air quality is monitored without targeted pollution removal, then general air quality can be assessed, but indoor air pollution sources cannot be effectively controlled and removed
Solution Approach 1:
The patent extracts and removes the harmful pollution source from the indoor environment. The system identifies kitchen units as specific pollution sources and uses exhaust devices to extract and remove contaminated air, separating the harmful pollutants from the indoor air supply to protect occupants
4Productivity
If multiple negative pressure exhausting devices are deployed above and in front of the cooking device, then air pollution can be rapidly exhausted, but the system complexity increases with multiple gas detectors and cloud computing servers
Solution Approach 1:
The patent segments the pollution control system into multiple functional components: gas detectors positioned above and in front of the cooking device, negative pressure exhausting devices, filter elements, and cloud computing servers. This segmentation allows each component to perform its specific function efficiently while enabling modular installation and maintenance
5Extent of automation
If cloud computing servers are used for intelligent computing and control command issuance, then pollution removal can be optimized, but the system requires real-time data transmission and processing infrastructure
Solution Approach 1:
The patent introduces a cloud computing server as an intermediary between the gas detectors and exhaust devices. The server receives real-time pollution data from detectors, performs intelligent analysis and computing, generates optimized control commands, and transmits them to the exhaust devices. This intermediary enables automated intelligent control while centralizing the complex data processing functions

AI summary
An air pollution prevention system for a kitchen unit in an indoor field includes a cooking device (H), negative pressure exhausting devices (A), gas detectors (1) and a cloud computing server (2). The negative pressure exhausting devices (A) are disposed above and in front of the cooking device (H) and respectively connected to exhausting channels (B). Each of the negative pressure exhausting devices (A) includes a fan (A1) and a filter element (A2). The gas detectors (1) detect air pollution and output air pollution information. The cloud computing server (2) receives the air pollution information, calculates the concentration of air pollution, and issues the control command to the negative pressure exhausting devices (A) to enable the fans (A1), so as to guide the air pollution to flow into exhausting channels (B) and pass through the filter elements (A2) for exhausting to the outdoor, thereby achieving a gas state in the kitchen unit with a level of air pollution close to zero.
