Solution Overview
Problem
Existing continuous positive airway pressure devices do not effectively protect users from breathing airborne particles, as they either lack comprehensive filtration or rely on portable air purifiers that may not provide continuous protection against ambient air.
Innovation Solution
A wearable continuous positive airway pressure device with shoulder straps, a face mask, and a face shield, which includes an intake hose with a filter and an exhaust hose to deliver filtered pressurized air, preventing the user from inhaling ambient air and protecting against airborne bacteria and viruses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing continuous positive airway pressure devices are used, then users can receive pressurized air, but they do not effectively protect users from breathing airborne particles due to lack of comprehensive filtration
Solution Approach 1:
The device divides the respiratory protection system into separate functional components: a face mask for seal and air delivery, a face shield for external particle blocking, and an integrated filter system. This segmentation allows each component to be optimized for its specific function while collectively providing comprehensive protection against airborne particles.
Solution Approach 2:
The filter is integrated within the face mask assembly, with the intake hose connected to a filter that is positioned inside the mask structure. This nested configuration allows the filtration system to be incorporated without significantly increasing external device complexity or bulk.
2Reliability
If portable air purifiers are used, then users can filter air, but they may not provide continuous protection against ambient air
Solution Approach 1:
The device merges the functions of a portable air purifier with a wearable respiratory protection system. The pressurized air source, filter, and delivery mechanism are integrated into a single wearable unit that continuously filters and delivers clean air to the user's face, providing reliable continuous protection while maintaining portability through the compact integrated design.
3Object-affected harmful factors
If a face mask is used to inhibit breathing ambient air, then users are protected from inhalation, but the device complexity increases
Solution Approach 1:
The face mask serves multiple functions simultaneously: it acts as a seal to prevent ambient air inhalation, a delivery conduit for pressurized filtered air, and an integration point for the filter and hose assembly. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while maintaining comprehensive inhalation protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures the user breathes filtered air, preventing inhalation of airborne contaminants and providing comprehensive protection against viruses and bacteria by using a combination of a face mask and face shield with a high-efficiency particulate air filter.
Implementation Method 1
a filter is fluidly coupled to the intake hose
Implementation Method 2
continuous positive airway pressure machine that has an intake and an exhaust
Data Source
AI summary
A wearable continuous positive airway pressure assembly for protecting a user from breathing airborne particles includes a continuous positive airway pressure machine that has an intake and an exhaust. A pair of shoulder straps is each coupled to the continuous positive airway pressure machine for wearing the continuous positive airway pressure machine on the user's back. An intake hose is fluidly coupled to the intake of the continuous positive airway pressure machine, a filter is fluidly coupled to the intake hose, and an exhaust hose is fluidly coupled to the exhaust of the continuous positive airway pressure machine. A face mask is fluidly coupled to the exhaust hose to receive the pressurized air from the exhaust hose thereby inhibiting the user from breathing ambient air.
