Breathing Filters TRIZ Cases
- Mask Ear Tab Structure for Hygienic Strap Separation
Pinch-and-pull tab portions let users separate mask ear materials without touching the mask body, helping maintain sanitary handling.
- Facepiece Respirator Adapter Sealing for Airway Instrumentation
A detachable adapter and sealed instrument slot help maintain face and device sealing during airway procedures while reducing aerosol exposure.
- Replaceable Filter Mask Frame for Facial Seal and Heat Control
A convex inner and outer frame assembly improves facial sealing across face shapes while reducing heat buildup, fogging, and moisture transfer.
- Rear-Surface Mask Airflow Layout for Lower Resistance and Noise
By moving both inlet and outlet to the mask rear surface, airflow turns are reduced, cutting resistance, noise, power use, and filter exposure.
- Nebulizer Face Mask Filtration With In-Mold Laminated Filters
Integrated nebulizer delivery and spunbonded filter windows reduce medication waste while maintaining a hygienic barrier against airborne microorganisms.
- UV Air Recirculation Chamber With Multi-Pass Irradiation
Multiple UV reflections in a compact recirculation chamber raise air disinfection efficacy while cutting UVC-LED power and energy demand.
- Smart Mask Air Impedance Control for Breathable Filtration
Sensors and AI adjust mask pore size to balance filtration risk with breathability, improving comfort and protection in changing conditions.
- Pouch-Style Respirator Strap Layout for Secure Comfortable Fit
Wide side-by-side elastic head straps improve respirator comfort and fit security while simplifying attachment during manufacturing.
- Flexible Dental Mask Pleat Structure for Close Cheek Adhesion
Segmented bonded and non-bonded pleats let the mask flex to the cheeks, improving leakage control and reducing glasses fogging.
- Cantilever Rib Nasal Dilator for Stable Septum-Free Dilation
Cantilever ribs and intermediary sections keep nasal passages open without septum pinching, improving fit stability and comfort during sleep or sport.
- Respiratory Blower Layout With Upstream Air Temperature Control
An upstream thermal unit heats or cools breathing airflow before the fan, enabling a compact wearable respiratory blower with guided channels.
- Two-Layer FFP2 Mask Structure for Filtration and Breathability
Thermally fused meltblown and spunbond polypropylene layers let an FFP2 mask meet EN149 filtration while reducing thickness and weight.
- Face Mask Color Indicator for End-of-Life Exposure Timing
A semi-permeable indigo and sodium dithionite indicator turns from blue to yellow to show when a face mask should be replaced.
- Rear-Surface Respirator Mask Layout for Lower Fan Power
Rear-surface inlet and outlet routing cuts flow resistance and fan power while shielding the filter and electronics from dust and moisture.
