A method for remotely controlling an air purification device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air purification device remote control systems do not consider the replacement of filters based on the working conditions and time of operation, relying solely on geolocalization information for operation control.
Innovation Solution
A method for remotely controlling air purification devices that includes setting initial configuration parameters via a user terminal, receiving geolocalization information, determining pollution parameters, and computing a filtering efficiency parameter using historical data to output instructions for operation and filter replacement, with the ability to automatically switch the device on or off and indicate filter replacement needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is implemented via cloud server using only geolocalization information, then device can be operated remotely, but filter replacement timing cannot be determined
Solution Approach 1:
The system implements feedback by having the air purification device send operational data (working hours, filter status) back to the cloud server. The server processes this feedback information and generates filter replacement recommendations, creating a closed-loop system that continuously monitors and responds to device status.
Solution Approach 2:
The system performs preliminary action by calculating and storing filter efficiency parameters in advance based on historical operational data. Before the user needs to replace filters, the system has already analyzed the data and prepared replacement recommendations, enabling proactive maintenance scheduling.
2Ease of manufacture
If filter replacement is determined only by fixed time intervals, then maintenance scheduling is simple, but filtering efficiency cannot be optimized based on actual working conditions
Solution Approach 1:
The system applies dynamics by transitioning from static, fixed-time maintenance schedules to dynamic schedules that adapt based on actual device usage patterns. The filter replacement timing is continuously adjusted according to real operational data, environmental conditions, and filter load variations.
Solution Approach 2:
The system changes parameters by using multiple variables (working hours, pollution levels, airflow resistance) instead of a single time-based parameter. These parameter changes enable the calculation of a comprehensive filter efficiency metric that reflects actual filter condition rather than just elapsed time.
3Reliability
If cloud server collects detailed operational data for filter efficiency calculation, then filtering efficiency can be optimized, but data transmission and processing complexity increases
Solution Approach 1:
The system extracts only the essential data elements needed for filter efficiency calculation (working hours, basic operational status) from the device and transmits them to the cloud server. Complex calculations and analysis are performed on the server side, keeping the device itself simple while achieving sophisticated filter management.
Solution Approach 2:
The cloud server acts as an intermediary that handles the complexity of data collection, processing, and analysis. The device communicates simple status information to the server, which then performs the complex computations and returns simplified recommendations, shielding the device from complexity.
