Breathing Filters TRIZ Cases
- Flat-Fold Respirator Flanges for Cup-Shaped Fit Stability
This case uses integral lateral and frontal flanges to preserve cup shape while improving respirator adjustment, fit, and storage.
- Convex Light-Transmitting Mask for Wider Lip-Reading Visibility
A convex light-transmitting sheet spreads lip visibility in a fan shape while the filter assembly supports mask air exchange.
- UV Decontaminating Mask for Exhaled-Air Cross-Contamination Control
This reusable mask combines inlet filtration, exhaust-chamber UV treatment, and check valves to limit cross-contamination and skin exposure.
- Reusable Filtering Face Mask With Detachable Trays for Sterilization
Explore a reusable face mask with modular filter trays, elastomeric sealing, speech transmission, and full disassembly for sterilization.
- Respirator Gasket Design for Airtight Eyewear-Compatible Fit
A flexible gasket with a deformable ridge conforms to facial contours, limiting air leakage and accommodating safety glasses.
- Respiratory Mask Liner Retainer for Moisture and Seal Comfort
This respiratory mask case uses an absorbent liner tethered by a retaining member to improve comfort while preserving seal integrity.
- Ultraviolet Decontaminating Mask With Dual Airflow UV Chambers
Check valves route inhaled and exhaled air through UV chambers, reducing pathogen transmission and PPE waste.
- Multi-Channel Respirator Valves for CO2 and Humidity Control
Separate nasal and oral channels with pressure-driven valves vent exhaled air while preserving filtration and user comfort.
- Adhesive Tape Release Liner for Mask Sealing
An adhesive tape with a removable release liner secures the mask to the face, preventing slipping and reducing fogging.
- Rotatable Mouth Panel Face Mask for Eating Without Removal
A face mask with a rotatable mouth panel allows users to eat and drink without removing the entire device.
- Ear-Mounted Cannular Nasal Filter with Air Mixing Chamber
Ear-mounted cannular filter recycles exhaled breath into an air mixing chamber, maintaining humidity and warmth while filtering particulates.
- UV LED Air Irradiation System with HEPA Filtration
Ultraviolet air irradiation system combines HEPA filtration with germicidal UV LEDs to neutralize viruses and bacteria, preventing pathogen transmission.
- Earless Filter Mask With Neck Closure and Multi-Layer Filtration
A multi-layer construction with an exhalation valve resolves the trade-off between filtration effectiveness and breathability while eliminating ear discomfort.
- Mouth-Only Respiratory Mask with Chin Cup Filter
A mouth-only respiratory mask uses a chin cup to anchor a filter element that covers the wearer's mouth while leaving the nose open.
- Adaptive Facial Garment with Conductive Textile Sensors
Conductive silver yarns in adaptive facial garments enable integrated sensing and actuation for real-time physiological monitoring.
- PAPR Face Shield with Foam Frame and Self-Adhesive Straps
Transparent face shield uses interior foam frame and self-adhesive straps to create a secure seal for powered air-purifying respirators.
- Breathing Apparatus Fan Control for Pressure Stability
A breath-synchronized motor fan applies micro-current during exhalation to maintain internal pressure.
- Bonded Continuous Filament Plenum for Respirator Filter Elements
Bonded continuous filament plenums distribute airflow evenly across filter media to prevent early clogging and reduce breathing resistance.
- Personal Space Protective Enclosure Using Gravity-Return Strips
Vertically-hanging strips create a protective barrier that returns to its resting position by gravity after disturbance.
