Steering Wheel Shift Switch Layout for Marine Vessel Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine vessel steering systems lack flexibility in switch layout and operability, particularly when shifting between autopilot and fixed point holding modes, due to limited space on the maneuvering seat and the need to operate switches with one hand while maneuvering.
Innovation Solution
Integrating shift switches for autopilot and fixed point holding modes directly onto the steering wheel, allowing operators to control these modes without removing their hands from the wheel, thereby improving switch layout flexibility and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic maneuvering switches are provided on the panel or joystick located at the maneuvering seat, then the marine vessel can shift to autopilot mode and fixed point holding mode, but the limited space on the panel or joystick makes it difficult to provide other switches
Solution Approach 1:
The patent segments the control functions by separating the automatic maneuvering switches from the main panel/joystick and relocating them to the steering wheel. This segmentation allows the panel to maintain its existing layout while the steering wheel gains additional functionality, resolving the space constraint issue.
Solution Approach 2:
The patent adds control functionality to a different dimension by placing switches on the steering wheel rather than on the two-dimensional panel surface. This dimensional shift provides additional space for switches without complicating the existing panel layout.
2Ease of operation
If the automatic maneuvering switch is located away from the steering wheel on the panel or joystick, then the switch can be provided, but the marine vessel operator needs to operate the steering wheel with one hand and the switch with the other hand, making it not easy to operate the switch accurately
Solution Approach 1:
The patent merges the automatic maneuvering switches with the steering wheel, combining two previously separate control elements into one integrated unit. This allows the operator to access both steering and mode-changing functions from a single location, improving ease of operation.
Solution Approach 2:
The steering wheel acts as an intermediary that brings the automatic maneuvering switches within easy reach of the operator's hand while steering. This intermediary position eliminates the need to stretch or shift hands between separate control locations.

AI summary
A marine vessel equipped with a steering mechanism for a marine vessel that is able to not only improve the flexibility in the layout of switches but also improve the operability of the switches is provided. The marine vessel includes the steering mechanism for the marine vessel. The steering mechanism for the marine vessel includes a steering wheel. The steering wheel includes shift switches that cause the marine vessel to shift to a course holding mode for holding a course of the marine vessel, and a traveling direction maintaining mode for maintaining a traveling direction of the marine vessel, respectively.
