Single-Command Marine Vessel Control for Steering and Trim Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling marine vessels require multiple operator commands to adjust steering, trim, and other structural elements, which can be cumbersome and inefficient, especially in dynamic operating conditions.
Innovation Solution
A system that utilizes a single operator command to control both a first and second structural element of a marine vessel, incorporating an input device, sensors, and a controller to manage engine function variables and vessel dynamics, allowing simultaneous adjustment of propulsion unit position, steering, and trim using actuators and sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operator commands are used to control different structural elements, then each element can be adjusted independently, but the operator workload and system complexity increase
Solution Approach 1:
The patent combines multiple control functions into a single integrated control system. The controller receives a single operator command and coordinates the adjustment of multiple structural elements (propulsion unit position, steering, trim) simultaneously, reducing operator workload while managing system complexity through unified control logic.
Solution Approach 2:
The control system is designed with multi-functionality to handle various control tasks through a single command interface. The controller can adjust propulsion unit position, steering angle, and trim settings based on one operator input, making the system versatile and reducing the number of separate controls needed.
2Productivity
If multiple structural elements are adjusted simultaneously, then vessel performance improves, but the precision of individual element control may be compromised
Solution Approach 1:
The control system incorporates feedback mechanisms where sensors detect the position and status of multiple structural elements, and the controller continuously adjusts their positions based on this feedback. This closed-loop control ensures that simultaneous adjustments maintain the required precision for each element while optimizing overall vessel performance.

AI summary
A system for controlling a marine vessel comprises an input device for inputting an operator command, a sensor which senses and signals an engine function variable or a vessel dynamic variable, and a first structural element and a second structural element. The first structural element and the second structural element each control speed or direction of motion of the marine vessel, and the first structural element and the second structural element each affect the marine vessel dynamic variable. There is a controller which receives the operator command and the engine function variable or the vessel dynamic variable. The controller moves the first structural element and the second structural element based on the engine function variable or the vessel dynamic variable, after receiving the single operator command.
