Breathing Filters TRIZ Cases
- Carbon Nanotube Filter Layer for PM 2.5 Mask
A carbon nanotube filter layer provides efficient particulate filtration in protective masks.
- Conformal Filter Housing for Respirator Mask Integration
A concave filter housing design with integral ribs supports a flat platform to minimize protrusion and reduce respiratory resistance.
- Scented Nose Covering for Infant Odor Masking
A scented foam nose covering releases aroma to mask infant feces odor, reducing parental stress during diaper changes.
- Splash Resistant Facemask Layer Stiffness and Weight Balance
Controlled basis weight and drape stiffness in spunbond splash layers achieve high air permeability without fluorocarbon treatments.
- Face Covering With Localized Gasket Seal
A face covering uses a conforming gasket to secure the mask while minimizing breathing resistance.
- Mask Filter With Detachable Coupling Portions For Size Adjustment
A mask filter incorporates detachable coupling portions to adjust size and shape for individual facial dimensions.
- Violet Light Nozzle Decontamination for Head Wearable Air Purifiers
A head wearable air purifier uses violet light sources to illuminate and decontaminate the nozzle via photo-oxidation.
- Flat-fold respirator attachment mechanisms for shape stability
Attachment mechanisms connect mask panels to tabs, preventing collapse and resolving the trade-off between storage volume and shape stability.
- Bioplastic Respirator Mask with Sliding Gate and Segmented Filters
A bioplastic respirator mask integrates a sliding gate and segmented filters to enable eating and speaking without removing the device.
- Activated Carbon Adsorber Housing Segmentation
Segmented activated carbon adsorber housing resolves the contradiction between reliable air filtration and ease of installation through detachable half spheres.
- Inflatable Nostril Seal for Pathogen Blocking
Segmented inflatable donuts accommodate asymmetry and enable speech, preventing airborne pathogens from entering the nasal cavity.
- Smart Masks with Embedded QR Codes for Contactless Payments
Embedded electronic devices in smart masks replace physical card terminals, reducing virus transmission risk during commerce.
- Hydration Mask Apparatus for Hazardous Environments
Segmented hydration assembly maintains respiratory protection while enabling continuous fluid intake in hazardous atmospheres.
- Active Airflow Mask With Dual Filtration
A fan-driven mask uses dual filters to move air through separate pathways.
- TRPM8 Agonist Nostril Application for Mask Thermal Stress
Topical TRPM8 agonists applied to nostrils simulate cool airflow sensations, reducing thermal stress and sensory discomfort during prolonged mask use.
- Scented Face Mask Filter with Phytochemical Diffusion
A scented face mask filter integrates a diffusing structure to release volatile phytochemicals alongside air purification.
- Bayonet Respirator Mask Filter Module Attachment
Non-circular geometry prevents accidental loosening while maintaining secure attachment.
- Face Mask Strap Engagement Teeth Friction Mechanism
A face mask assembly uses strap engagement teeth to provide frictional resistance against the first strap for selective position adjustment.
- Filtering Facepiece Respirator with Sealing Layers
A filtering facepiece respirator incorporates detachable sealing layers around an instrument port to maintain a protective barrier.
- Rear-Intake Mask Reduces Flow Resistance and Power Consumption
Relocating the air inlet to the rear surface eliminates front-flow conversions, lowering power consumption and extending filter lifespan.
- CPAP Mask Pivot Arm with Threaded Slider for Leak Reduction
Threaded sliders on a CPAP mask pivot arm adjust fit to reduce air leaks while maintaining user comfort.
- Active Ventilation Mask for Pressure Stability
Variable speed fans regulate airflow to maintain consistent pressure, reducing discomfort from breathing fluctuations.
- Reusable Mouth Mask With Welded Plastic Layers
Segmenting the filter from the welded mask body resolves manufacturing complexity while enabling high-volume production.
- Wearable Dome Assembly with Acoustic Material and Seal Ring
A wearable dome assembly integrates acoustic material and a flexible seal ring to isolate sound and block environmental hazards.
- Miura-Folded Respirator Filter for Compact High-Capacity Filtration
A respirator filter folded into parallelograms expands surface area within a compact housing.
- Breathing Mask Continuous Cover Layer and Elastic Side Sections
Continuous nonwoven cover layer spans central and side sections, eliminating seams to reduce manufacturing complexity while ensuring air sealing.
