Protective Mask Actuation Control for Adaptive Respiratory Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective masks require manual handling, which can lead to contamination, damage, or forgetting to wear them when necessary, and existing automated masks are cumbersome or inefficient in managing respiratory protection based on environmental conditions.
Innovation Solution
A control system for a protective mask that uses information signals to automatically adjust between closed and open states based on environmental conditions, reducing respiratory flow resistance and ensuring proper mask usage without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling of protective masks is used, then device complexity is reduced, but reliability of mask usage and protection against contamination decreases
Solution Approach 1:
The mask system automatically monitors environmental conditions and adjusts its state without manual intervention. Sensors detect air quality parameters and trigger automatic opening/closing of the mask, making the system self-regulating and eliminating the need for manual operation while ensuring consistent protection.
Solution Approach 2:
The system incorporates sensors that continuously monitor environmental conditions (air quality, particulate matter, gases) and provide feedback to a control unit. Based on this feedback, the control unit automatically adjusts the mask state, creating a closed-loop control system that ensures reliable protection while adapting to changing conditions.
2Ease of operation
If automated control based on environmental conditions is implemented, then reliability and convenience are improved, but device complexity and cost increase
Solution Approach 1:
The mask automatically monitors and responds to environmental conditions without requiring user intervention. The system self-adjusts based on sensor input, making operation as simple as wearing the mask while maintaining high reliability through automated environmental response.
3Reliability
If the mask remains closed continuously, then respiratory protection is maintained, but respiratory flow resistance increases and comfort decreases
Solution Approach 1:
The mask transitions from a static closed state to a dynamic system that automatically opens and closes based on real-time environmental conditions. The mask remains closed when protection is needed and opens when environmental quality is good, optimizing both protection and comfort through adaptive behavior.
Solution Approach 2:
Sensors provide continuous feedback on air quality, enabling the control system to make real-time decisions about mask state. When air quality is good, the mask opens to improve breathing comfort; when pollution is detected, the mask closes to maintain protection, creating an optimal balance between comfort and safety.
4Reliability
If manual mask removal is required, then device complexity is reduced, but risk of contamination and damage increases
Solution Approach 1:
The mask system automatically manages its own protection state and can be integrated with automated removal or storage systems. The mask monitors when it is no longer needed and can automatically transition to a storage state or be removed by external mechanisms, eliminating manual handling and associated contamination risks.

AI summary
A technique for controlling an actuator of a protective mask configured to assume selectively a closed state for respiratory protection and an open state is described. A respiratory flow resistance of the open state is reduced compared to a respiratory flow resistance of the closed state. As to a method aspect of the technique, at least one information signal indicative of an environment of the protective mask is received. A control signal is sent to the actuator of the protective mask for assuming selectively the closed state and the open state depending on the at least one information signal.
