Vehicle Loading System with Horizontal and Vertical Motion Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for receiving additional vehicles in vehicles like motorhomes and yachts are complex, laborious, and inefficient, often requiring inclined ramps or lifts that waste space and compromise the structural integrity or visual appeal of the vehicle.
Innovation Solution
A system with a guide assembly and two movement assemblies, allowing horizontal and vertical movement independently, enabling objects to be easily and safely loaded and unloaded without the need for external devices, maintaining a compact design and preserving the vehicle's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inclined ramp is used to load additional vehicles, then loading is simplified, but space is wasted and the structure becomes complex
Solution Approach 1:
The patent transitions from a traditional inclined ramp (2D sloping surface) to a vertically moving platform (1D linear motion along guide rails). This dimensional change eliminates the need for triangular ramp structures, freeing up significant space within the vehicle while maintaining loading functionality through vertical elevation rather than angular inclination.
Solution Approach 2:
The loading system is divided into independent functional components: guide rails for vertical movement, a separate horizontal translation mechanism, and the loading platform itself. This segmentation allows each component to be optimized independently and reduces the overall spatial footprint compared to a monolithic ramp structure.
2Ease of operation
If a lift with supporting frame is used, then vehicles can be loaded, but the floor must be partially omitted or made removable, increasing complexity and cost
Solution Approach 1:
The guide rails serve multiple functions: they provide vertical guidance for the platform, support the horizontal translation mechanism, and structurally reinforce the vehicle floor without requiring removal or special modifications. This multi-functionality eliminates the need for dedicated lift openings while maintaining loading capability.
Solution Approach 2:
Instead of creating a complex custom lift structure, the patent uses standardized guide rail components that can be vertically positioned and horizontally translated. This approach replicates the essential function of a lift using simpler, more modular elements that integrate with the existing vehicle structure.
3Ease of operation
If cables are made freely accessible for the lift mechanism, then operation is simplified, but safety hazards increase
Solution Approach 1:
The patent introduces an intermediate control mechanism that mediates between the operator and the cable system. Rather than direct manual manipulation of freely accessible cables, a controlled interface (such as a winch or automated control system) manages cable tension and movement, maintaining operational capability while eliminating safety hazards associated with exposed cables.
4Ease of operation
If the receiving area is widened to allow person access, then loading is easier, but space for storage is reduced
Solution Approach 1:
The patent provides person access through vertical movement along narrow guide rails rather than requiring wide horizontal clearance. Operators can safely access the platform at elevated positions through compact vertical pathways, eliminating the need for wide receiving areas and preserving maximum storage space within the vehicle.

AI summary
The present invention relates to a system (1, 2, 3) for accommodating objects, comprising a guide assembly (1), which can be arranged in a stationary manner, a first motion assembly (2), which is connected to the guide assembly (1) and which can be moved horizontally in the direction of a longitudinal axis (X) in relation to the guide assembly (1), and a second motion assembly (3), which is connected to the first motion assembly (2) and which can be moved vertically in the direction of a vertical axis (Z) in relation to the first motion assembly (2) and can accommodate objects, wherein the first motion assembly (2) can be moved out in the direction of the longitudinal axis (X) so far over the guide assembly (1) that the second motion assembly (3) can be moved in relation to the first motion assembly (2) past the guide assembly (1) in the direction of the vertical axis (Z).
