Emergency Oxygen Systems TRIZ Cases
- Aircraft Lavatory Alcove Layout for Cabin Space and Seating
An alcove-based modular aircraft lavatory frees cabin space for added seating or seat pitch while preserving FAA-compliant exit paths.
- Breathing Gas Backup Regulator With Pneumatic Pressure Control
A pneumatic backup regulator replaces a calibrated orifice to maintain comfortable breathing gas pressure without electrical power.
- Aircraft Oxygen Pressure Reducer for Stable High-Flow Supply
A piston reducer with an axial flow path and radial control chamber keeps aircraft oxygen outlet pressure stable at higher mask flow rates.
- Aircraft Oxygen Pressure Reducer for Stable High-Flow Outlet Pressure
A piston-based pressure reducer uses an axial flow path and radial control chamber to keep aircraft oxygen outlet pressure stable at high flow.
- Plastic Attachment Clip for Tool-Free Aircraft Rail Fastening
A single-piece elastic plastic clip fastens aircraft rail-mounted units without tools, cutting parts, weight, and assembly effort.
- Aircraft Oxygen Pressure Regulator With Sensor-Based Demand Flow
Pressure and temperature feedback let the regulator meter oxygen by demand and altitude, cutting waste while maintaining mask pressure.
- Breathing Gas Regulator With Pressure-Regulated Backup Oxygen
A pneumatic pressure regulator in the backup line prevents overpressure and low flow, improving pilot comfort and extending mission duration.
- Aircraft Breathing Gas Monitoring for Oxygen and CO2 Alerts
Real-time oxygen and carbon dioxide sensing helps aircraft crews detect unsafe breathing gas conditions and trigger timely alerts.
- Mechanical Oxygen Release for Breath and Altitude Compensation
A mechanical initiator and aneroid metering device tailor oxygen flow to inhalation and ambient pressure without continuous electrical power.
- Dosed Oxygen Delivery Tube Bypass for Moisture Blockage Prevention
Continuous trickle flow and gas pulses keep aircraft oxygen delivery tubes clear, supporting reliable passenger respiration detection.
- Aircraft Oxygen Mask Dynamic Flow Control
Real-time blood saturation monitoring modulates oxygen flow rates to eliminate oversupply and reduce consumption by half.
- Adaptive Aircraft Oxygen Supply System for Breathing Frequency Control
Breath sensors detect passenger inhalation rates to dynamically adjust oxygen flow, preventing premature depletion during cabin pressure loss emergencies.
- Aircraft Cockpit Mask With Integrated Video Display
Mask with integrated video display projects flight data onto shared viewing surface, maintaining situational awareness in smoke-filled cockpits.
- Mask Stowage Door Securement Mechanism for Vibration Resistance
Monolithic elastic U-shaped bracket resists lateral separation of striker and retainers, preventing inadvertent door opening during acceleration.
- Electromechanical Oxygen Valve Actuation
Replacing binding mechanical cables, an electric motor with worm gear actuates the valve to ensure reliable remote operation and pressure regulation.
- Aircraft Stowage Bin Assemblies Decoupled from Oxygen Systems
Decoupling stowage bin assemblies from passenger service units and emergency oxygen systems increases overhead cabin space.
- Aircraft Oxygen Module Segmentation for Flexible Layout Adaptation
Segmented oxygen modules with partial opening test modes resolve assembly errors and simplify maintenance across changing aircraft seat layouts.
