Steering Initiations TRIZ Cases

Wind and current vectors reshape electric boat range into a directional battery map, improving range-to-empty accuracy and reducing range anxiety.

Joystick thrust control coordinates multiple propulsion devices to hold lateral vessel movement against wind, current, yaw, and fore-aft drift.

Predicted yaw from trim tab deployment and vessel speed is countered with steering compensation to keep marine heading stable.

An integrated hub protrusion and stopper regulator limits steering wheel rotation with fewer parts, simpler assembly, and less harness strain.

Coordinated steering and auxiliary lateral thrust help a jet propulsion boat turn more safely and with less driver effort during maneuvers.

Automatic trim-down control limits prolonged bow-up attitude to reduce hull loads and protect engine lubrication and cooling.

Three independently controlled 120° thrusters use vector calculations to move a boat in any direction with precise heading and rotation control.

Adjustable helm tilt uses paired pivots, a lock mechanism, and electromagnetic brake resistance to improve steering operability and secure angle holding.

When adjacent water jets raise steering load torque, the controller limits twin propulsive force to keep both propulsion units on target.

Intermittent Hi/Low throttle pulses with coordinated rudder control help ships turn more accurately at low speed without side thrusters.

Independently controlled water resistance bodies help a marine hull follow a drifting buoy, reducing line entanglement and propulsion use.

Mode-based propulsion and rudder response adjustment reduces overshoot and improves ride comfort during low-speed automatic heading changes.

Hand-position sensors on a fixed steering wheel generate steering signals without rotation, avoiding cable twisting, wear, and contact failures.

Selectable joystick steering modes let marine drives match user steering preference during reverse-thrust yaw maneuvers.

Integrated processing in a marine control input adjusts saturation from obstacle distance, cutting latency and improving close-range maneuvering.

Selectable joystick response modes switch between wheel-like and direct yaw mapping, improving reverse-thrust maneuvering for marine drives.

Integrated processing in a marine control input uses obstacle distance to adjust saturation, reducing latency and easing vessel integration.

A threaded mount, liner, and screw-adjusted extension fit different boat steering axle lengths without panel drilling, enabling easier autopilot installation.

An electric auxiliary thruster with a wider steering angle rotates the hull without main thrust, simplifying control and cutting CO2 emissions.

When bow azimuth deviation grows, coordinated thrust reduction cuts ship speed to shrink turning radius and limit course-change overshoot.

Placing the manual engagement member at the reduction gear output cuts emergency steering turns while keeping lubrication access and a compact layout.

Alternating rear-drive thrust and steering with a bow lateral drive enables precise sideways vessel motion despite limited single-drive angles.

Periodic forward-reverse thrust with bow lateral thrust cancels unwanted surge, enabling precise sway movement from a single rear drive.

Coordinated bow-thruster and single outboard thrust creates lateral watercraft motion without requiring multiple outboard motors.

Acceleration and heading sensing separate object strikes from environmental drift, preventing damaging correction attempts in marine drives.

Automatic GPS-based thrust and steering control keeps a jet-propelled boat within a target anchor range for rescue, fishing, and low-fuel station keeping.

A geared rack fixed relative to the lower jacket lets an absolute sensor track steering column axial position accurately during stow and rake motion.

Dual steering sensors are fused to detect faults and switch smoothly to backup sensing, reducing uncommanded steering changes in marine drives.
