Boat Transom Rear Platform with Pivotable Hatch for Outboard Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marine outboard engines mounted on transoms limit the size of the rear platform, creating limited usable space and obstructing access to the engine, as the platform must be discontinuous or on different levels to accommodate the engine's presence.
Innovation Solution
A marine outboard engine with a bumper connected to its housing that fits under a pivotable hatch, allowing the engine to be positioned under the rear platform, enabling the hatch to pivot open and providing access while maintaining the platform's continuity and increasing usable space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the marine outboard engine is mounted on the transom, then the engine is properly positioned for operation, but the rear platform size is limited and usable space is reduced
Solution Approach 1:
The engine is positioned within the space defined by the rear platform and hatch, nesting the engine mounting arrangement within the existing boat structure to maximize space utilization without compromising access
Solution Approach 2:
The hatch is made pivotable to provide dynamic access to the engine, allowing the platform to maintain continuity while enabling user access when needed
2Area of stationary object
If the rear platform extends above the marine outboard engine, then more space is provided, but access to the engine from above is limited
Solution Approach 1:
The hatch is designed to be pivotable rather than fixed, enabling it to open and provide access to the engine from above while still allowing the platform to extend and provide additional space when closed
3Area of stationary object
If the rear platform is made continuous across the transom, then usable space is increased, but the engine mounting becomes more complex
Solution Approach 1:
The bumper acts as an intermediary element between the engine and the hatch, simplifying the mounting structure by providing a direct abutting interface that enables continuous platform design without complex engine mounting arrangements

AI summary
A boat having a transom and a rear platform extending at least partially across the transom. The rear platform includes a hatch defining at least partially the rear platform, the hatch having a bottom surface, and a hatch pivot for pivoting the hatch about a hatch pivot axis from a first hatch position to a second hatch position. The boat is free of an enclosed engine compartment. The hatch at least partially defines thereunder a space for receiving a marine outboard engine. The space extends rearwardly of the transom and is open at a rear of the boat.
