Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respirator face masks do not adequately customize air flow to meet the specific needs of individual users, leading to potential discomfort and inefficiency in breathing and battery usage.
Innovation Solution
A powered face mask with a variable speed fan controlled by a processor that adjusts fan speed based on user-specific data, environmental conditions, and sensor inputs, balancing air flow with power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed speed fan is used in the respirator mask, then the device structure is simple, but the air flow cannot be customized to meet individual user needs
Solution Approach 1:
The patent implements a variable speed fan that can adjust its rotation speed dynamically based on user-specific data, transforming the static fixed-speed system into a dynamic adaptive system. This allows the air flow to be customized for different users while managing the complexity through controlled variability rather than complete redesign
Solution Approach 2:
The patent changes the operational parameter of the fan from a fixed speed to a variable speed controlled by a processor. By adjusting the fan speed parameter based on user data, the system achieves air flow customization without requiring a completely different device architecture
2Ease of operation
If the fan speed is increased to provide more air flow, then breathing comfort is improved, but battery power is consumed faster
Solution Approach 1:
The patent implements a feedback control system where the processor monitors user-specific data and breathing needs, then adjusts the fan speed accordingly. This feedback mechanism ensures the fan provides sufficient air flow for breathing comfort while avoiding excessive speed that would unnecessarily deplete battery power
Solution Approach 2:
The variable speed fan dynamically adjusts its operation based on real-time conditions and user needs. Rather than running at constant high speed, the fan operates at the minimum necessary speed to provide comfortable breathing, thereby optimizing battery consumption while maintaining ease of operation

AI summary
Embodiments relate generally to respirator face masks, and specifically to powered face masks which may be custom-controllable to better provide for the specific air needs of the individual user wearing the mask. For example, the face mask embodiments typically include a filter and a motorized fan, both generally located on the face mask itself, along with a processor. The processor then may use inputs, for example specific to the user and/or the environment, to control the fan speed. Thus, the fan speed of the face mask may be custom controlled to provide the appropriate amount of filtered air as the specific user needs it.
