Ship Steering Parameter Setup With Parallel Thrust Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initial setting of control parameters for a ship's propulsors in a joystick-based steering system is cumbersome and time-consuming, requiring separate adjustments for forward and reverse thrust parameters, which complicates the setting process and prolongs the work time.
Innovation Solution
A steering system for ships that allows simultaneous input of forward and reverse thrust parameters through separate input devices (electronic gauge and joystick) with real-time reflection, enabling parallel setting while confirming the ship's action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If control parameters are set one by one while switching setting items using an electronic device, then each parameter can be adjusted individually, but the workload increases and setting time is prolonged
Solution Approach 1:
The setting process is segmented into two independent parallel channels: forward thrust parameter setting and reverse thrust parameter setting. Each channel has its own input device and can be operated independently, allowing simultaneous adjustment without interference between settings.
Solution Approach 2:
The patent merges the setting functions for forward and reverse thrust parameters into a unified parallel processing system where both parameters are reflected to the propulsors simultaneously. This combines previously sequential operations into concurrent execution, reducing total setting time while maintaining precision.
2Manufacturing precision
If multiple control parameters are adjusted sequentially, then each parameter receives focused attention, but the overall setting workload increases
Solution Approach 1:
The control system is divided into separate input devices for forward and reverse thrust parameters. This segmentation allows each parameter to be set independently with focused attention while the other is simultaneously being set, reducing the sequential workload without sacrificing precision.
Solution Approach 2:
Each input device independently handles its assigned parameter setting and the controller automatically reflects both parameters to the propulsors. The system serves itself by automatically coordinating the parallel settings without requiring manual switching or complex coordination by the operator.
3Adaptability or versatility
If separate setting procedures are used for forward and reverse thrust parameters, then each parameter can be optimized independently, but the setting process becomes more complex
Solution Approach 1:
The setting process is segmented into independent forward and reverse thrust parameter channels, each with its own input device. This allows independent optimization of each parameter while the overall system complexity is managed through the simple parallel architecture that requires no complex coordination between settings.

AI summary
A steering system (1) is employed in a ship to which left and right propulsors (2L, 2R) are attached. The steering system (1) includes a first input device (11) configured to receive an input of any one of a forward thrust parameter and a reverse thrust parameter of the propulsors, a second input device (15) configured to receive an input of the other of the forward thrust parameter and the reverse thrust parameter of the propulsors, and a controller (17) configured to reflect the forward thrust parameter and the reverse thrust parameter to the propulsors in real time. In the steering system, the first input device and the second input device receive the inputs in parallel when a steering pattern for a ship is set.
