In-Car Air Exchange Control for Pollution-Aware Cabin Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing air pollution due to harmful pollutants like carbon dioxide, carbon monoxide, formaldehyde, bacteria, fungi, VOCs, and particulate matters in enclosed car spaces poses a significant threat to human health, necessitating an effective method for maintaining clean and breathable air inside vehicles.
Innovation Solution
A method involving an in-car gas exchange system comprising an air-conditioning unit, a cleaning unit, and a control driving unit that detects pollutants outside and inside the car, uses artificial intelligence to determine if outside air should be introduced to filter and purify the interior air, ensuring it remains safe and breathable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If gas exchange system is activated to filter and purify air continuously, then air quality inside the car is improved, but energy consumption increases
Solution Approach 1:
The gas exchange system operates periodically rather than continuously. The control unit activates the gas exchange operation when detection data shows polluted gas concentration exceeds predetermined thresholds, and deactivates it when thresholds are satisfied, thereby reducing unnecessary energy consumption while maintaining air quality
Solution Approach 2:
The system uses detection units to continuously monitor gas concentration inside and outside the car, and the control unit adjusts the gas exchange operation based on this feedback. When polluted gas is detected above thresholds, the system activates filtration and gas exchange; when thresholds are met, it deactivates, creating a closed-loop control that optimizes energy usage
2Object-affected harmful factors
If gas exchange operation is performed frequently, then polluted gas is removed effectively, but loss of time occurs due to system activation/deactivation cycles
Solution Approach 1:
The system performs preliminary gas exchange operations when pollution thresholds are first detected, establishing a buffer of clean air inside the car. This allows the system to remain inactive for longer periods afterward, reducing the frequency of activation/deactivation cycles and minimizing time loss while still maintaining air quality
3Use of energy by moving object
If intelligent selection is used to determine gas exchange timing, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit automatically determines when gas exchange operations should be activated or deactivated based on detection data from the detection units. The system compares detected gas concentrations with predetermined thresholds and autonomously controls the gas exchange operation without requiring manual intervention, achieving energy efficiency through intelligent automation while keeping the control logic relatively simple

AI summary
A method for preventing and handling in-car air pollution includes providing an out-car gas detector to detect a polluted gas outside a car and transmit an out-car gas detection data; providing an in-car gas detector to detect a polluted gas in an interior space of the car and transmit an in-car gas detection data; providing an in-car gas exchange system for controlling and determining whether to introduce a gas outside the car into the interior space, where the in-car gas exchange system includes a cleaning unit for filtering and purifying the polluted gas in the interior space and a control driving unit for receiving and comparing the out-car gas detection data with the in-car gas detection data; and filtering and exchanging the polluted gas in the interior space after the control driving unit compares the out-car gas detection data with the in-car gas detection data.
