Propulsive Elements Of Rotary Type TRIZ Cases
- Thrust Vectoring Modules for Decoupled Payload and Trajectory Control
Independent rotor and arm vectoring decouples payload orientation from trajectory, improving agility, disturbance response, and stability.
- Pool Cleaner Rotating Unit With Stopper-Based Reversing Control
Reciprocating stoppers and a buoyant plate coordinate reversing in a pool cleaner, preventing spin-in-place and improving cleaning coverage.
- Marine Propulsor Slewing Bearing Single-Stage Gear Design
A marine propulsor uses a slewing bearing with an integrated single-stage transmission gear to drive rotary blades.
- Propeller Winglets for Centrifugal Loss Reduction
Spiral winglets define variable volume channels that direct fluid rearward, minimizing centrifugal loss and preventing cavitation during high-speed rotation.
- Air-Driven Rotor Propulsion Mechanism for Maritime Vessels
Compressed air evacuates water from rotor vanes to improve efficiency while eliminating combustion emissions in coastal zones.
- Cycloidal Marine Propulsion Electric Blade Control
Independent electric motors replace mechanical gearboxes to control blade orientation, reducing drag and vibration at high speeds.
- Marine Foil Wheel Propulsion Torque Management
Dynamic pitch angle profiles manage peak motor torque while boosting bollard pull thrust by 33%.
- Paddle Wheel Yacht High-Speed Propulsion
Symmetrical paddle wheels flap the water surface to generate forward and upward forces, reducing drag and improving stability at high speeds.
- Tugboat Propulsion Positioning for Heading Control
Longitudinal propulsion positioning uses hydrodynamic resistance to correct heading control without increasing engine thrust.
- Voith-Schneider Propeller Thrust Control via Variable Pitch
Variable pitch blades adjust thrust without altering diesel engine speed, reducing fuel consumption and mechanical wear during ship maneuvering.
