Steering Rudders TRIZ Cases
- Magnetic Transducer for Watercraft Control
A magnetic unit transduces mechanical displacement into electronic signals via a magnet and sensor assembly.
- Marine Rudder Assembly Separate Casting Interference Fit
Separate casting of rudder stock and blade eliminates fairing compound bonding failures while maintaining structural integrity under cyclic loads.
- Switchable Pilot Control Forces for Aircraft Trim Stability
Segmented force generation isolates manual control sensitivity from high autopilot loads, preserving the pre-set trim point during pilot intervention.
- High-Lift Rudders for Ship Deceleration Without Engine Reversal
High-lift rudders generate astern power from propeller slipstream to decelerate ships while maintaining forward rotation.
- Air-Thrust Propulsion Unit for Shallow Water Navigation
A detachable air-thrust propulsion unit mounts on boat gunwales to enable shallow water navigation.
- Marine Power Steering Flow Limiting Valve Chatter Control
A marine power steering system uses a flow limiting valve to control hydraulic fluid rates and ram speed.
- Retractable Keel and Rudder for Shallow Water Navigation
A ship hull uses a posture switching mechanism to retract keel and rudder, avoiding bottom collision in shallow water while maintaining deep water navigation.
- Dual-rudder mechanism with telescopic pivot for sailboat tilt
Telescopic rudder pivot extends during tilt to decouple higher rudder rotation, eliminating water resistance and preventing speed loss.
