Steering Rudders TRIZ Cases
- Air Bubble Generator for Rudder Resistance Reduction
A pneumatic air bubble generator introduces gas into the water stream to isolate the rudder surface, lowering fuel consumption caused by excessive drag.
- Marine Outboard Power Steering Electronic Torque Sensor
Electronic torque sensor replaces bulky hydraulic hoses in marine outboard motors, maintaining steering precision through precise signal processing.
- Lateral Thrust Device for Watercraft Reverse Steering
Segmented deflector channels redirect reverse jet flow to generate lateral thrust, resolving counterintuitive steering and limited turning radius in watercraft.
- Life Jacket With Integrated Rudder For Current Navigation
A life jacket with an integrated dorsal fin rudder enables swimmers to steer through strong water currents using a simple cord mechanism.
- Boat Steering Control System with Pulsed Reaction Torque
A boat steering control system applies pulsed reaction torque to counteract external forces acting on the watercraft.
- Electrically Assisted Hydraulic Steering System for Marine Craft
A controller activates the hydraulic pump only during steering maneuvers, eliminating parasitic losses from continuous belt-driven operation.
- Variable-Incidence Hydrofoil Assembly for Shallow Water Safety
A variable-incidence hydrofoil assembly adjusts lift characteristics via an integral control mechanism.
- Ship Propulsion Rudder Interface Curvature Cavitation
Curved rudder cavity fits support protrusion to minimize cavitation at high speeds.
- Parallel Power Steering Layout for Small Vessels
A parallel power steering layout reduces vertical length on a common base.
