Breathing Filters TRIZ Cases
- Mask Device With Partition Plate And Dual Air Cleaners
A mask device uses a partition plate and dual air cleaners to filter outside air, preventing mixing of exhaled and filtered air for better breathing comfort.
- Respirator Exhalation Valve Flashing Flap Design
Band shifting film on the valve flap flashes during movement, providing visual confirmation of proper operation without adding mechanical complexity.
- Self-Retaining Curved Filter Cartridge Design
Stiff cup-shaped casing and curved lid compress loose filter material into a uniform bed without external support structures.
- Elastic Textile Holder for Body-Conforming Thermal Pack Positioning
Segmented reusable holders and disposable packs resolve cost trade-offs while maintaining consistent heat transfer via localized elasticity.
- Replaceable Filter Cartridge Face Mask with Threaded Closure
Segmenting the mask body from a replaceable filter cartridge resolves the trade-off between consistent seal reliability and easy cartridge replacement.
- Respiratory Filter Accessory Cap with Downward Air Passage
Downwardly facing air passage restricts liquid ingress via gravity while pivotable pre-filter web enables dual shower and filtration functionality.
- Wearable Air Purifier With Pivoting Mask For Compact Storage
A head-mounted air purification system uses a moveable mask and support to deliver filtered air while enabling compact stowed storage.
- Integrated Patient Interface for Ventilator Data Communication
An electronic device integrated into a patient interface uses embedded conductors to exchange data with a ventilator, resolving calibration complexity.
- Mouthpiece Respirator Seal for Facial Hair Compatibility
Segmented mouthpiece and nose plug bypass facial hair to maintain reliable filtration seals.
- Annular Moisture Absorbing Element for Respiratory Mask
A peripheral absorbing element reduces fogging and discomfort while maintaining low breath resistance.
- Respiratory Half-Mask Strap Guide for Stable Sealing
A respiratory half-mask with a strap guide part and clamping element secures side straps to the mask body.
- Transparent Mask With Porous Resin Film
A transparent mask uses a resin film with through holes to allow air and sound permeability.
- Pleated Respirator Openwork Support for Facial Conformity
Openwork flexible plastic layers support pleated filter media in a respirator, resolving the trade-off between structural rigidity and facial conformity.
- Respirator Stiffening Member for Structural Integrity
Integral stiffening members formed by welding S-shaped pleats reinforce the mask body, preventing collapse under pressure from dirty or moisture-laden air.
- Face Mask With Neck Hanger Oxygen System
A face mask integrates a neck hanger with fans and filters to deliver purified air.
- Filter Mask With Transparent Face Plate and Downward Air Inlet
Downward air inlet prevents rain ingress while transparent face plate maintains visibility.
- Mask Structure With Air-Isolator Prevents Leakage
An air-isolator guides air through a reduced-area main filtering layer, preventing particle leakage at bonding zones.
