Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the in-car gas exchange system introduces external air into the vehicle, then the air freshness is improved, but the air pollution from external environment is also introduced
Solution Approach 1:
The purification device serves as an intermediary between external air and the vehicle interior. It filters harmful substances from incoming air while allowing fresh air to enter, thus mediating the contradiction between air exchange needs and pollution prevention
Solution Approach 2:
The gas detection device continuously monitors air quality both inside and outside the vehicle, providing feedback to the control device. This feedback loop enables dynamic adjustment of the gas exchange system to maintain optimal air quality while preventing pollution intake
2Object-affected harmful factors
If the purification device filters air continuously, then the air quality is improved, but the energy consumption increases
Solution Approach 1:
The purification device operates dynamically based on real-time air quality conditions. The control device adjusts the purification intensity and gas exchange rates according to detected pollution levels, enabling the system to be energy-efficient when air quality is good while providing strong purification when pollution is detected
Solution Approach 2:
The system changes operational parameters (purification intensity, air exchange rate) based on detected air quality conditions. When external air quality is poor, the system reduces air exchange and increases purification; when air quality is good, it increases air exchange and reduces purification, thus optimizing energy consumption
3Measurement precision
If multiple detection devices are installed, then the air quality monitoring is improved, but the device complexity increases
Solution Approach 1:
The control device performs multiple functions: it receives data from multiple detection devices, analyzes air quality conditions, controls the gas exchange system, and manages the purification device. This multi-functionality reduces the need for separate control units for each subsystem, thereby managing complexity while maintaining high measurement precision

AI summary
A method of preventing air pollution in a vehicle is disclosed. Firstly, an out-car gas detection device, an in-car gas detection device and a purification device are provided to detect the air pollution and transmit a respective gas detection datum to a connection device. An in-car gas exchange system is provided for intelligently selecting and controlling a gas outside the vehicle to be introduced or not introduced into the inner space of the vehicle. The connection device receives and compares the gas detection data, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the purification device, and the air pollution in the inner space of the vehicle is exchanged and filtered, so as to provide clean, safe and breathable air.
