Gas Handling Applications TRIZ Cases
- Liquefied Gas Containers With CO2 Inerting to Prevent Liquid Formation
This case replaces nitrogen with CO2 to prevent liquid formation and support pressure-based leak detection in cryogenic containers.
- Bidirectional Hydrogen Fueling Parameter Exchange For Safer Compatibility
The case uses mobility-dispenser parameter exchange to negotiate protocols and adapt hydrogen fueling in real time.
- Hydrogen Refuelling Gas Verification Through Vehicle Tank Measurements
Compare station meter readings with vehicle pressure and temperature data to detect hydrogen quantity discrepancies during refuelling.
- Cryogenic Storage Pipe for Thermo-Acoustic Pressure Production
A shut-off valve controls thermo-acoustic oscillations in a cryogenic tank, raising pressure without heaters, blowers, or pumps.
- Hydrogen Fueling Feedback for Real-Time Pressure Ramp Control
Pressure and temperature data from the CHSS dynamically adjust the ramp rate, keeping hydrogen fueling within preset safety thresholds.
- Cryogenic Hydrogen Storage Control for Boil-Off Loss Prevention
This case adjusts hydrogen charge before vehicle stops to limit tank pressure, prevent boil-off, and avoid gaseous hydrogen venting.
- Vehicle Hydrogen Storage Charge Control for Cryogenic Boil-Off
The control system uses route, stop-duration, and tank-level data to avoid venting hydrogen during extended vehicle stops.
- Demountable Aeronautical Cryogenic Tank With Leak-Tight Access
Demountable cryogenic tanks help preserve leak-tight insulation during aircraft maintenance.
