Boat Hauling Vehicle With Adjustable Support Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current boat hauling and launching vehicles are unable to easily navigate areas with varying slope differences, requiring multiple vehicles and resulting in time-consuming and risky transfers, especially when dealing with boats in basins with inclined bottoms or ramps with different slopes.
Innovation Solution
A vehicle with a 'U'- or 'H'-shaped frame and hydraulically controlled telescopic cross-bar, equipped with swiveling carriages and adjustable support posts to maintain the boat's inclination relative to the travel plane, allowing for smooth operation on varying slopes and inclinations, either manually or automatically using electronic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-slope vehicle is used, then it can operate on a specific slope, but it cannot adapt to varying slope differences requiring multiple vehicles
Solution Approach 1:
The vehicle employs dynamically adjustable support legs with telescopic sections and articulation joints that can independently adapt to varying slope angles. The support legs can extend, retract, and articulate to maintain vehicle stability on ramps with different inclinations, eliminating the need for multiple fixed-slope vehicles.
Solution Approach 2:
The vehicle changes its geometric parameters (support leg length, articulation angles) in response to varying slope conditions. By adjusting these parameters, the vehicle can operate on ramps with different slope angles, achieving versatility without increasing overall system complexity.
2Reliability
If multiple vehicles are used for different slopes, then each vehicle can be optimized for its specific slope, but transfer time increases and damage risk increases
Solution Approach 1:
The vehicle is designed as a universal platform that can handle boats on various slope configurations through its adjustable support legs. This multi-functionality eliminates the need to transfer boats between multiple specialized vehicles, reducing both transfer time and the risk of hull damage.
Solution Approach 2:
The support system is segmented into multiple independently adjustable support legs, each capable of adapting to different slope angles. This segmentation allows the vehicle to maintain stability and safety across varying terrain without requiring multiple complete vehicle systems.
3Stability of the object's composition
If the support structure is rigid, then it provides stable support, but it cannot adapt to varying inclinations and extensions
Solution Approach 1:
The support structure incorporates dynamic elements including telescopic sections that can extend and retract, and articulation joints that can pivot to match varying inclinations. These dynamic components maintain structural stability while adapting to different slope angles and terrain conditions.
Solution Approach 2:
The support structure is divided into segmented components (telescopic sections, articulation joints) that can independently adjust their position and angle. This segmentation allows each component to contribute to both stability and adaptability, resolving the contradiction between rigid support and flexible adjustment.
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
Enables seamless hauling and launching of boats across different slope conditions, reducing transfer time and risk of damage, and accommodating boats of various sizes by maintaining the boat's hull parallel to the water plane during movement, even on sandy bottoms.
Implementation Method 1
Said posts are three in number for each side of the vehicle. In addition, the middle post has a fixed length, whereas the two posts adjacent thereto are telescopic. Still according to the invention, the upper support structure is therefore articulated to the lower frame so as to vary its distance and/or inclination relative to the frame depending on the inclination and extension of the telescopic posts.
Implementation Method 2
carriages for hauling, launching and transporting a boat are known, which can be moved along a surface such as a ramp, in a harbor or in a shipyard
