Rotatable Outboard Motor Deck for Ship Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to improve space utilization on vessels equipped with electric outboard motors, as traditional designs do not efficiently utilize the space above the motor body.
Innovation Solution
The design includes an outboard motor deck provided directly above the outboard motor body, which allows for effective use of the space above the motor, enhancing space utilization and facilitating easier maintenance and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If an outboard motor deck is provided directly above the outboard motor body, then space utilization on the vessel is improved, but the tilt-up mechanism may be interfered with
Solution Approach 1:
The outboard motor deck is designed to be movable rather than fixed, capable of rotating about one side to move between a horizontal position (for space utilization) and a raised position (for tilt-up operation). This dynamic configuration allows the deck to adapt its state based on operational requirements, resolving the contradiction between maintaining space efficiency and enabling easy tilt-up access.
Solution Approach 2:
The outboard motor deck is divided into a stationary support structure and a movable deck portion that can be independently raised. This segmentation allows the deck to be partially lifted to clear the tilt-up path while maintaining the structural integrity and spatial benefits of having a deck above the motor body.
2Ease of repair
If the outboard motor deck is made rotatable to facilitate maintenance, then accessibility is improved, but the structural complexity increases
Solution Approach 1:
The rotatable deck introduces a single degree of freedom motion capability, allowing the deck to pivot to an inclined position for maintenance access. This dynamic feature provides easy repair capability while maintaining relatively simple structural implementation through a hinge connection and actuation mechanism.

AI summary
The present invention enhances the utility of space in a ship. A ship 100 comprises a hull 10, an electric outboard motor 70, a hull deck 21, and an outboard motor deck 27. The electric outboard motor 70 comprises an outboard motor body 60 provided with a propeller and an electric motor for driving the propeller, and an attachment part 50 for attaching the outboard motor body 60 to a rear part of the hull 10. The hull deck 21 overlaps with at least a portion of the rear part of the hull 10 as seen from above. The outboard motor deck 27 is provided above the outboard motor body 60, and overlaps with at least a portion of the outboard motor body 60 as seen from above.
