Propeller Parts TRIZ Cases
- Marine Propulsion Drive Shaft with Dual Opposed Threads and Taper
Dual opposed threads and a tapered section on the drive shaft eliminate keyway misalignment, reducing vibration and maintaining torque transmission.
- Outboard Motor Transmission Lubrication Circuit Design
A propulsor-driven pump circulates lubricant through a dedicated circuit to the transmission and angle gears, preventing filter blockages via a bypass valve.
- Aqua Lift Man Lift Translatable Brackets
Translatable mounting brackets and inflatable pontoons stabilize a raised man lift during repositioning to prevent instability in wave-prone areas.
- Buoyant Toothed Rollers for Shoreline Hull Protection
Rotating buoyant toothed rollers on a protruding flotation structure protect the hull from rocks and debris during high-speed shoreline navigation.
- Diffuser Endplate Propeller Cavitation Control
Curved endplates with optimized radii diffuse flow at outer sides, preventing sheet cavitation that increases resistance and hull vibration.
- Magnus Rotor Body Segmented Panel Assembly
Segmented arcuate panels minimize deformation and wobble in rotating machinery.
- Asymmetric Propulsion System for Aquatic Vehicles
An asymmetric propulsion system uses unevenly distributed propeller blades to generate axial thrust and lateral maneuverability from a single rotating axis.
