Electronic Device Dust Filter Maintenance Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require manual checking of dust filter maintenance, which is inefficient and lacks automation for determining when the filter needs cleaning.
Innovation Solution
An electronic device incorporating a shell, fan, dust filter assembly, wind speed sensor, and controller that automatically determines if the dust filter needs cleaning by comparing detected air flow rates, eliminating the need for manual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual checking method is used to determine dust filter maintenance needs, then device complexity is low, but productivity is low and loss of time occurs
Solution Approach 1:
The system enables self-service by allowing the electronic device to automatically monitor its own dust filter status through the wind speed sensor and controller, which continuously detect air flow rates and compare them against threshold values to determine when maintenance is needed, eliminating the need for external manual inspection
Solution Approach 2:
The patent replaces the mechanical/manual inspection process with an automated sensing and control system. The wind speed sensor electronically detects air flow characteristics, and the controller processes this data to automatically determine maintenance needs, substituting human manual checking with an electronic automation system
2Loss of time
If manual inspection method is used, then device complexity is low, but loss of time occurs due to frequent user intervention
Solution Approach 1:
The system implements continuous feedback by using the wind speed sensor to monitor air flow rates in real-time, comparing detected values against predetermined thresholds, and automatically generating maintenance notifications when degradation is detected, creating a closed-loop monitoring system that eliminates the need for user intervention
Solution Approach 2:
The electronic device performs self-monitoring and self-diagnosis of its dust filter status through the integrated sensor and controller system, which automatically tracks performance degradation and notifies users only when maintenance is actually needed, freeing users from routine manual checking

AI summary
An electronic device includes a shell, a fan, a dust filter assembly, a wind speed sensor, and a controller. The shell includes an accommodation space. The fan is arranged in the accommodation space. The dust filter assembly is at least partially arranged at an air opening of the shell and is configured to filter dust. The wind speed sensor is arranged on a side of the air opening of the fan and is configured to detect a first flow rate of air on the side of the air opening of the fan. The controller is electrically connected to the wind speed sensor and is configured to determine whether the dust filter assembly needs to be cleaned based on the first flow rate and a determined flow rate.
