Breathing Mask Venting System Predictive Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breathing masks are uncomfortable to wear for extended periods due to high breathing resistance and increased temperature, CO2, and humidity levels, which prior active venting systems have not adequately addressed while also consuming excessive power.
Innovation Solution
A breathing mask with a venting system controlled by a detector and controller that predicts future respiration cycles based on historic data, activating the venting system before inhaling or exhaling to maintain comfortable conditions with low power consumption, using sensors for temperature, humidity, CO2, and oxygen levels, and adjustable airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If active venting systems are installed in the breathing mask to reduce temperature, CO2 and humidity levels, then user comfort is improved, but power consumption increases
Solution Approach 1:
The controller predicts future respiration data based on historic respiration data and activates the venting system before the determined future inhaling or exhaling cycle commences. This preliminary action allows the venting system to be activated proactively based on predicted breathing patterns rather than reactively responding to current conditions, optimizing the timing of ventilation to maintain comfort while minimizing unnecessary operation and power consumption.
2Object-affected harmful factors
If active venting systems are installed in the breathing mask to ventilate the mask, then temperature, CO2 and humidity levels are controlled, but device complexity increases
Solution Approach 1:
The controller uses historic respiration data provided by the detector to predict future respiration data and automatically determines when to activate the venting system. This self-service approach allows the system to autonomously manage ventilation based on predicted breathing patterns without requiring external intervention or complex manual control mechanisms, thereby reducing device complexity while maintaining effective control of CO2, temperature, and humidity levels.
3Ease of operation
If the venting system is activated continuously to maintain comfortable conditions, then user comfort is improved, but power consumption increases
Solution Approach 1:
The controller activates the venting system periodically based on predicted respiration cycles rather than continuously. By predicting future inhaling or exhaling cycles using historic respiration data and activating the venting system only before these predicted cycles, the system provides comfortable ventilation intermittently rather than continuously, significantly reducing power consumption while maintaining user comfort during actual breathing events.
Data Source
AI summary
A breathing mask including a vent system for ventilating the mask, a detector for providing respiration data of a user and located for sensing at least one physical property of air inside the breathing mask when worn by a user and a controller configured to activate the vent system based on the respiration data. The controller may be configured to predict future respiration data based on historic respiration data of at least one earlier detected inhaling or exhaling cycle, determine whether a future inhaling or exhaling cycle will occur based on predicted future respiration data and activate the vent system before the determined future inhaling or exhaling cycle commences.
