Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for converting caravans and vehicles for land-water use are complex and do not allow for equivalent intensive use on both land and water, with difficulties in assembly and disassembly, and limitations in accessibility during transport and water usage.
Innovation Solution
An amphibious caravan design featuring a detachable cuboid housing container attached to a chassis with flexible, rotatable rods and platforms that can fold down to accommodate boats, allowing for easy transition between land and water use, utilizing support wheels and adjustable mechanisms for seamless conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If floating bodies are detachably fastened on the roof of the caravan trailer, then the caravan gains buoyancy for water use, but the accessibility of the container is limited during transport state
Solution Approach 1:
The platforms are designed to be movable between different positions - folded up during transport to clear the rear opening, and folded down during water use to provide access. This dynamic reconfiguration allows the same structure to serve different functions in different operational states, resolving the contradiction between water usability and transport accessibility
Solution Approach 2:
The floating bodies are divided into multiple separate platforms that can be independently positioned. The rear platform can be folded up separately from the side platforms, allowing the rear opening to be accessible during transport while the side platforms remain in position for structural support
2Adaptability or versatility
If the caravan is converted for water use with floating bodies, then buoyancy is achieved, but the assembly and disassembly process becomes complex
Solution Approach 1:
The floating bodies are integrated with the caravan structure through shared attachment points on the chassis. The platforms are combined with the support rods and attachment mechanisms to form a unified conversion system, reducing the number of separate components that need to be assembled and disassembled
Solution Approach 2:
The floating bodies are pre-positioned on the chassis in a ready state, with attachment mechanisms prepared in advance. The platforms are designed to be quickly secured to the chassis using pre-installed attachment points, eliminating the need for complex on-site assembly procedures
3Adaptability or versatility
If support wheels are used for land-water transition, then the caravan can be moved onto water, but the transition process requires overcoming friction and precise timing
Solution Approach 1:
Support wheels are introduced as an intermediary element to facilitate the transition between land and water. The wheels provide a mechanical interface that allows the caravan to be rolled onto the floating bodies with reduced friction, making the transition process smoother and more controllable
Solution Approach 2:
The support wheels are positioned and adjusted to create an equipotential transition path between the land-based caravan and the water-based floating bodies. By aligning the wheels at appropriate heights and positions, the transition requires minimal force to overcome friction, making the process easier to execute

AI summary
The invention relates to an amphibious caravan consisting of a separate living container (1) detachably arranged on a chassis (2), which is equipped on each longitudinal side with platforms (8) that can be accessed later, and on its front and/or rear, which are folded against the container (1) in the driving state and are to be folded down in the water state so that they are locked in a nearly horizontal position at a height such that the container (1) is supported above the waterline, wherein boats of appropriate size and load-bearing capacity, which are used as floats, are detachably attached to the platforms (8 and 10) which are raised in the driving state.that in the water state they support the container in a floating position resting on the water and which can be removed in the folded-down state and are to be used as intended and have additional foldable platforms (12) for the lateral extension of the usable area outside the container in the floating state and for connecting the platforms (8 and 10), which are rotatably mounted on the outer longitudinal edges of the platforms (10) by 180°.
