Propulsive Elements TRIZ Cases
- Collapsible Sea Scooter Arms With Waterproof Motor Sealing
Pivotable arms and a skeleton-sealed motor make the sea scooter compact to store while blocking water and sand ingress in saltwater use.
- Marine Thrust Bearing Liner Isolation Against Deposit Wear
An electrically isolated bearing liner blocks cathodic current paths, reducing marine deposits, wear, and early thrust assembly failures.
- Controllable Pitch Propeller Hydrophilic Hydraulics for Leak Tolerance
Hydrophilic water-glycerin hydraulics let controllable pitch propellers keep operating through leaks while reducing pollution and maintenance.
- AUV Magnetometer Compensation for Vehicle Magnetic Interference
Calibration maneuvers and compensation coefficients remove AUV magnetic interference, enabling accurate subsea geological mapping without extra specialists.
