Electronic Mask Automatic Fan Control via Pressure Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic masks require manual operation, which can be inconvenient, especially when both hands are occupied or when the user cannot see the operation button, as they rely on direct button pressing to control fan functions for inhalation and exhalation.
Innovation Solution
An electronic mask with a pressure sensor and processor that automatically controls fan operations based on measured atmospheric pressure, identifying preset events such as inhalation and exhalation without user input, using stored default atmospheric pressure information and adjusting settings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used to control fan operations, then the device structure remains simple, but the ease of operation deteriorates when hands are occupied or visibility is limited
Solution Approach 1:
The mask system automatically detects breathing patterns through pressure sensors and controls fan operations without requiring user intervention. The processor identifies inhalation and exhalation events based on atmospheric pressure changes and autonomously activates the fan module accordingly, enabling the device to serve itself.
Solution Approach 2:
The patent replaces manual mechanical button pressing with an automated sensing and control system. Pressure sensors detect breathing-induced atmospheric pressure changes, and the processor translates these signals into automated fan control commands, substituting mechanical operation with sensor-based automation.
2Ease of operation
If automatic control based on pressure sensing is implemented, then ease of operation improves, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The pressure sensor serves multiple functions: detecting atmospheric pressure changes, identifying breathing patterns, and triggering fan operations. The processor handles both pressure data analysis and fan control logic, making these components multi-functional to minimize overall device complexity while achieving automatic operation.
