Boat Platform Linkage for Horizontal Lifting on Angled Transoms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile platform devices for boats, which raise and lower using hydraulic cylinders, often displace the platform horizontally, causing it to move closer to or away from the transom, especially on boats with non-vertical transoms, leading to inefficiencies and potential cantilevered positioning.
Innovation Solution
A mobile platform device with synchronized actuation means that control the pivoting of support arms and platform rotation, combined with translational movement along a perpendicular direction, maintaining the platform in a horizontal plane regardless of the transom configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support arms are lengthened to adapt to non-vertical transoms, then the platform can be positioned correctly, but the platform becomes cantilevered and unstable when raised
Solution Approach 1:
The invention adds translational movement along the Z-axis (perpendicular to the pivot axis) to the traditional rotational movement. This dimensional addition allows the platform to maintain proper positioning and stability when raised, eliminating the cantilevered effect that occurs with lengthened support arms on non-vertical transoms.
2Ease of operation
If the platform is mounted to pivot on the end of support arms, then the platform can be raised and lowered, but horizontal displacement occurs bringing the platform closer to or away from the transom
Solution Approach 1:
By introducing movement along the Z-axis (perpendicular direction) in addition to the traditional rotational movement around the horizontal pivot axis, the system can compensate for horizontal displacement. This dual-degree-of-freedom mechanism maintains the platform at a constant distance from the transom while enabling raising and lowering operations.
3Ease of operation
If hydraulic cylinders are used to raise and lower the platform, then the platform can be positioned at different heights, but the platform rotates and loses horizontal orientation
Solution Approach 1:
The invention couples rotational movement around the horizontal axis with translational movement along the perpendicular Z-axis. This combination allows the platform to change height while maintaining its horizontal orientation, as the translational component compensates for the rotational displacement that would otherwise cause the platform to tilt.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The platform maintains a horizontal position during raising and lowering, adapting to various transom configurations, ensuring stable and efficient operation.
Implementation Method 1
the raising and lowering of the support arms by rotation around a horizontal axis... One of the pulleys is fixed to the end of the hydraulic cylinder rod, so that the advance of this rod causes the support arm to descend by rotation around a horizontal axis
Implementation Method 2
On the opposite free end of these support arms, a platform is mounted in an articulated fashion, again around a horizontal axis parallel to the pivot axis of the support arms
Implementation Method 3
One of the pulleys is fixed to the end of the hydraulic cylinder rod, so that the advance of this rod causes the support arm to descend by rotation around a horizontal axis under the weight of the arm and the platform it carries

AI summary
The invention relates to a mobile platform device (1) for a boat, comprising at least one support arm (2) provided, at a first end (3), with articulated fastening means (4) designed to pivotally attach said support arm (2) to a boat about an axis X. This support arm (2) further comprises a second end (5), opposite the first (3), on which a platform (6) is articulated about an axis Y, parallel to X. The mobile platform device (1) further comprises hydraulic or motor-driven actuation means (7) for jointly controlling the pivoting of the support arm (2) about the axis X and the rotation of the platform (6) about the axis Y. Advantageously, this platform (6) is also mounted in translation on the end (5) of the support arm (2) along a direction Z, perpendicular to the axis Y.
