Breathing Masks TRIZ Cases
- Respiratory Mask Acoustic Ribs and Ventilation Channels
Porous acoustic insulation material absorbs sound waves through structural ribs, balancing ventilation performance against noise reduction requirements.
- Head Suspension Pivot Joints for Respirator Hood Angle Adjustment
Pivot joints lock the angle between headbands to maintain stable force distribution during wear.
- Respiratory Mask Nose Support Extension Design
A respiratory mask nose region features a support extension extending away from the seal to provide structural stability.
- Curved Touch-Screen Panel Manufacturing via Intersecting Region Removal
Removing intersecting regions before bending prevents cracks in curved touch-screen panels while maintaining electrode pattern alignment.
- Dual-Molded Polyamide-Silicone Composite Bonding
An ethylene-vinyl alcohol copolymer enables autogenous bonding between polyamide and silicone, resisting high-temperature water degradation.
- Magnetic Pass-Through Controller for In-Helmet Display Adjustment
A magnetic pass-through controller rotates an in-helmet display via external magnets and a swing arm mechanism.
- Elastic Tubular Device for Low-Pressure Aircraft Mask Harness
An elastic tubular device with a silicone inner tube and aramid sheath expands longitudinally to secure an aircraft breathing mask.
- Scalable Aircraft Cargo Fire-Suppression Agent Distribution
A scalable cargo fire-suppression agent distribution system selects a subset of supply source units based on flight conditions to adjust flow rates.
- Head-Mounted Air Filtration Device for Respiratory Protection
A wearable headgear unit filters ambient air and directs it toward the user's breathing zone.
- CPAP Mask Mouth Seal One-Way Air Path
A nasal mask mouth seal redirects exhaled air through a one-way path to the nasal interface.
