Propulsive Elements TRIZ Cases
- Watercraft Trim System Adaptive Nozzle Control
A watercraft trim system pivots a nozzle via a control unit to adjust operating angles based on detected conditions.
- Propeller Shaft Seal Arrangement with Pressure Differential Control
Intermediate compartment air pressure stays below seawater levels, reducing component count and simplifying maintenance access for propeller shaft sealing.
- Propeller Blade Pitch Adjustment via Indexed Limit Stop Abutment
Indexed slots on the propeller hub modify limit stop abutment positions, resolving imprecise manual grub screw adjustments.
- Vessel Propulsion Nozzle Deflector F Bucket Lateral Thrust
A vessel propulsion apparatus uses a forward bucket to tilt water streams from a deflector, generating lateral thrust for turning.
- Movable Nozzle Biasing for Personal Propulsion Control
Adjustable biasing components on a movable nozzle resolve the contradiction between maneuverability and stability in personal propulsion devices.
- Variable Pitch Propeller Stopping Maneuver Control
A control system adjusts blade angles during watercraft stopping maneuvers to minimize the required stopping distance.
- Watercraft Impeller Reversal Linkage for Debris Clearance
A watercraft propulsion system inverts impeller rotation via a disconnected direct linkage to clear jet clogs.
- Jet Propulsion Venturi Door Mechanism for Watercraft Clog Clearance
Movable venturi doors open apertures during reverse rotation to clear debris clogs and maintain thrust without manual hull access.
- Ship Propulsion Control Unit Optimizing Power for Cavitation Prevention
A control unit adjusts power to ship propellers based on real-time operating parameters.
