Solution Overview
Problem
Current indoor air purifying devices are either fixed or require manual operation, limiting their ability to accurately identify and remove pollution sources across large spaces, especially when multiple sources with changing emission intensities are present.
Innovation Solution
An automatic source-seeking device equipped with pollutant concentration sensors, a control unit, position sensors, a moving mechanism, a telescopic device, and a filtering and purifying system, which identifies pollution sources and adjusts its movement to collect pollutants at any position and height, using Tikhonov regularization to determine hourly release rates and positions of sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If air purifying devices are placed in fixed positions or require manual movement, then the device structure is simple and easy to operate, but the device cannot accurately identify and reach pollution sources in large spaces
Solution Approach 1:
The patent combines the air purification function with mobile robot navigation and pollution source identification capabilities into an integrated system. The air purifier is mounted on a mobile platform that can autonomously navigate to identified pollution sources, merging three separate functions (purification, navigation, identification) into one unified device that resolves the contradiction between simplicity and effectiveness.
Solution Approach 2:
The system enables the air purifying device to autonomously locate and navigate to pollution sources without requiring manual operation. The mobile platform self-navigates based on identification data from sensors, allowing the device to service itself by automatically positioning at optimal purification locations.
2Area of stationary object
If traditional air purifiers are used in large indoor spaces, then the device structure is simple, but the purification coverage is insufficient and cannot handle multiple pollution sources
Solution Approach 1:
The patent transforms the static air purifier into a dynamic mobile system that can move throughout the indoor space. The mobile platform allows the purification device to dynamically reposition itself to different locations and pollution sources, dramatically expanding the effective coverage area and improving productivity by addressing multiple contamination points sequentially.
3Measurement precision
If pollutant concentration sensors are used to identify multiple pollution sources, then the identification accuracy improves, but the calculation time increases due to repeated concentration field simulations
Solution Approach 1:
The system performs preliminary identification of pollution sources using sensor data before initiating the mobile purification process. By pre-identifying source locations and concentrations, the system avoids time-consuming repeated simulations during the purification phase, reducing overall calculation time while maintaining identification accuracy.
