Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mask pore size is reduced to filter out small viral particles, then filtration efficacy is improved, but breathability deteriorates
Solution Approach 1:
The patent employs a mesh network with adjustable pore diameter that can dynamically change its filtration characteristics. The mesh structure allows the pore size to be modified in real-time based on environmental conditions and user needs, enabling the system to switch between high-filtration mode (small pores) and high-breathability mode (large pores), thus resolving the contradiction between filtration efficacy and breathability
Solution Approach 2:
The invention changes the physical parameter of pore diameter to resolve the contradiction. By controlling the mesh network to adjust its pore diameter between small and large states, the system can optimize both filtration performance (when pores are small) and breathability (when pores are large), allowing dynamic parameter adjustment to satisfy different operational requirements
2Reliability
If N95 masks are worn for high protection, then virus filtration is improved, but comfort and breathability deteriorate
Solution Approach 1:
The system dynamically adjusts the mesh pore diameter based on real-time environmental assessment and user physiological data. When high virus filtration is needed, the mesh contracts to small pores providing N95-level protection. When protection is less critical, the mesh expands to large pores for comfortable breathing, thus resolving the contradiction between virus filtration and comfort
Solution Approach 2:
The patent incorporates sensors that continuously monitor environmental virus levels and user physiological parameters (breathing rate, comfort level). This feedback loop allows the system to automatically adjust mesh pore diameter to provide appropriate protection levels, avoiding excessive filtration when not needed and thus maintaining comfort while ensuring adequate virus filtration when required
3Reliability
If mask filtration is increased to block pathogens, then protection level is improved, but air impedance increases reducing breathability
Solution Approach 1:
The mesh network dynamically adjusts its pore diameter to control air impedance. When high protection is required, the mesh adopts small pore configuration that naturally increases air impedance but provides superior pathogen blocking. When protection requirements are lower, the mesh expands to large pores, reducing air impedance and improving breathability, thus resolving the contradiction between protection level and air impedance
Solution Approach 2:
The invention changes the physical parameter of pore diameter to simultaneously control both protection level and air impedance. By adjusting pore size, the system optimizes the balance between filtration performance (protection level) and respiratory resistance (air impedance), allowing parameter optimization based on real-time conditions
4Adaptability or versatility
If multiple masks are maintained for different scenarios, then adaptability to different environments is improved, but device complexity and user burden increase
Solution Approach 1:
The patent creates a universal mask system that can perform multiple functions by dynamically adjusting its mesh pore diameter. A single mask device provides both high-filtration protection (N95 mode) and comfortable breathing (breathable mode) capabilities, eliminating the need for users to maintain multiple different masks for different scenarios, thus resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The mesh network's dynamic adjustability allows one mask to adapt to different environmental conditions and protection requirements. The system transitions between different operational states (high filtration, high breathability) based on real-time sensor data and user needs, providing scenario-specific performance from a single universal device, thereby resolving the contradiction between adaptability and complexity

AI summary
While facing polluted environments one does not need extreme breath filtering protection all the time. Methods of the art hardly focus on breathability aspect while working on smart masks. Embodiments of the present disclosure provide a system and method for context aware networked mask with dynamic air impedance for optimum breathability. The system provides a smart mask that regulates the air inlet (by modulating the position/pore size of filtering membrane or by using resizable gel) as per the prevalent risk at that instance. The context aware mask with a mesh network, disclosed herein, comprises sensors and processing unit, which use contextual information and Artificial Intelligence to develop models for generating alerts along with mechanism of dynamically regulating the pore size to ensure breathability by adjusting air impedance.
