Pleasure Boat Launching System with Movable Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for launching and hauling water crafts on pleasure boats require significant space, complex kinematic systems, and manual intervention, posing challenges in space optimization and safety, especially in open sea conditions.
Innovation Solution
A system featuring a platform movable between a flush position within the garage room and a submerged position, with independent handling assemblies for automatic transfer of the water craft using guides and cradles, allowing for remote control and minimizing space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inclined plane with rollers and sliders is used for launching and hauling water craft, then the water craft can be moved along the inclined plane, but large spaces are required which contradicts space optimization requirements in pleasure boats
Solution Approach 1:
The invention transitions from a horizontal inclined plane system to a vertical platform system. The platform moves vertically between a first position (flush with garage room floor) and a second position (below water surface), eliminating the need for large horizontal space while maintaining launching and hauling functionality.
Solution Approach 2:
The system divides the launching/hauling function into two independent handling assemblies: one in the garage room for moving the cradle horizontally to the platform, and another on the platform for moving the cradle vertically. This segmentation allows each assembly to be compact and specialized.
2Stability of the object's composition
If a platform with complex kinematic system is used to maintain horizontal position during movement, then the platform remains parallel to floor and water surface, but maintenance complexity and failure risks increase
Solution Approach 1:
The invention extracts the horizontal positioning function from the moving platform system. The platform simply moves vertically between two fixed positions without requiring complex kinematic mechanisms to maintain horizontal orientation, as the vertical movement inherently preserves platform stability.
Solution Approach 2:
Instead of using complex mechanisms to actively maintain horizontal position during movement, the system inverts the approach by using simple vertical translation where horizontal stability is naturally maintained without active control.
3Ease of operation
If manual intervention is required for transferring water craft between garage room and platform, then the transfer process can be controlled, but automation and convenience are reduced
Solution Approach 1:
The system enables automatic transfer of water craft between garage room and platform through two independent handling assemblies that operate autonomously. The first assembly moves the cradle horizontally, transfers it to the platform, and the second assembly moves it vertically, all without manual intervention.
Solution Approach 2:
The invention introduces a cradle as an intermediary device that receives the water craft in the garage room and facilitates its automatic transfer to the platform. The cradle serves as a mediator between the handling assemblies and the water craft, enabling automated operation.
4Area of stationary object
If the platform is kept flush with garage room floor when not in use, then additional space is provided for passengers, but the transfer operation becomes more complex
Solution Approach 1:
The platform is designed to be dynamic, moving between a first position (flush with garage room floor to maximize passenger space) and a second position (below water surface for launching/hauling). This dynamic repositioning allows the system to optimize for different functions without permanent structural compromise.
Solution Approach 2:
The transfer operation is segmented into two independent phases handled by separate assemblies: horizontal movement by the first handling assembly and vertical movement by the second handling assembly. This segmentation simplifies each individual transfer phase while enabling the platform to remain flush with the garage room floor when not in use.

AI summary
Pleasure boat (1) provided with a system for launching and hauling a water craft, such as a tender or a jet ski. The system for launching / hauling the water craft comprises a platform (11), which is movable at least from a first position, in which it is substantially flush with the floor of the parking area (7) of the boat, to a second position, in which it is below the water surface, a cradle (15) for the water craft, a guiding system for said cradle, comprising first guides (21) extending in the parking area and second guides (23) extending on the platform, and a handling system comprising a first handling assembly (33), arranged in said parking area and intended to move said cradle along said first guides, and a second handling assembly (35), arranged in said platform and intended to move said cradle along said second guides. The device allows to automatically transfer the water craft from said parking area to said platform, and vice versa, with no manual intervention.
