Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas detection module and cleaning device are integrated into the vehicle, then air quality monitoring and purification capability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The system is divided into separate functional modules: a gas detection module with sensor array, a cleaning device with filtration components, and a control module. Each module can be independently installed, maintained, and replaced, reducing overall system complexity while maintaining comprehensive air quality monitoring and purification capabilities
Solution Approach 2:
The external modular base is designed to accommodate multiple types of gas sensors (carbon monoxide, carbon dioxide, VOC, PM2.5, nitric oxide, sulfur monoxide detectors) and can interface with various cleaning devices, creating a universal platform that handles multiple air quality parameters and purification methods through a single integrated system
2Measurement precision
If real-time gas detection is implemented throughout the vehicle, then detection accuracy and response time are improved, but system cost and power consumption increase
Solution Approach 1:
The gas detection system operates with periodic sampling cycles rather than continuous monitoring, allowing the sensor array to take measurements at predetermined intervals. This approach maintains adequate detection accuracy for air quality monitoring while significantly reducing power consumption compared to continuous real-time monitoring
Solution Approach 2:
The system uses a sensor array with multiple sensors that can selectively activate based on detected gas levels. When air quality is good, only minimal sensing is performed. When hazardous gases are detected, the system activates additional sensors and increases monitoring frequency, providing excessive detection capability only when needed to maintain high measurement precision while managing power consumption
3Adaptability or versatility
If an external modular base with multiple connection ports is used, then system adaptability and installation flexibility are improved, but device complexity increases
Solution Approach 1:
The external modular base incorporates a universal power connector that can interface with various vehicle power sources and a standardized data connection port that works with different cleaning devices and detection modules. This universal interface design provides high installation flexibility and adaptability across different vehicle types and configurations
Solution Approach 2:
The external modular base serves as an intermediary component between the vehicle's existing electrical system and the air quality management system. It provides voltage regulation, signal conditioning, and standardized interfaces that simplify integration while managing the complexity of connecting multiple sensors and actuators to the vehicle's power and data networks
Data Source
AI summary
A gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.
