Underwater Equipment TRIZ Cases
- Snorkel Tube With External Float Shutter for Easy Breathing
External float and shutter hinges keep the snorkel tube cross-section constant, reducing breathing effort while blocking water entry.
- Breathable Mask Airflow Separation to Prevent CO2 Buildup
Separate intake and exhaust passages in a snorkeling mask prevent exhaled air mixing, reduce CO2 buildup, and improve water drainage.
- Breathing Regulator Pressure Reduction Without Spring Calibration
A movable balancing chamber replaces spring calibration to improve valve closure, reduce venting, and keep breathing gas flow stable.
- Diver Dry Suit Fluid Channels for Low-Bulk Thermal Management
Recessed fluid tubes in an insulated dry suit maintain diver temperature with less bulk, lower energy loss, and no electric shock hazard.
- PMP Artificial Gill Membrane for Underwater Gas Exchange
A hydrophobic PMP membrane and water flow path sustain O2 uptake and CO2 removal underwater without bulky air tanks or chemical scrubbers.
- Drysuit Stretch Panel Layout to Reduce Trapped Air
Longitudinal elastic panels compress loose drysuit regions to cut trapped air, improve fit across body types, and maintain waterproofing.
- Diving Mask Air-Cooling Channel to Prevent Lens Fogging
Finned airflow channels cool and dehumidify exhaled nose air before it reaches the lenses, helping a diving mask stay clear.
- Free Diving Weight Belt Buckle for Quick Accessory Reconfiguration
Knob-back screw fasteners let divers reconfigure accessories and secure excess belt quickly, reducing delay during underwater changes.
- Snorkeling Mask Airflow Layout for CO2 and Water Isolation
Partitioned chambers, one-way airflow, and a drain valve separate inhalation and exhalation to limit CO2 buildup and water ingress.
- Snorkeling Mask Airflow Separation for Nasal Breathing and Anti-Fogging
Separate upper and lower chambers with one-way intake and drain valves enable nasal breathing while preventing CO2 mixing and window fogging.
