Vehicle Transporter Plateau Vertical Lowering for Low Clearance Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car transporters with box bodies face difficulties in loading vehicles with low ground clearance, as they require driving up an inclined ramp, which is challenging and requires significant effort.
Innovation Solution
The car transporter features a plateau that can be lowered vertically using lifting elements, allowing it to rest horizontally on the road, eliminating the need for vehicles to drive up an inclined ramp, and includes castors for easier movement and retraction into the box body, along with motor-driven support devices for controlled extension and retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plateau is arranged in an inclined position for loading, then the loading process is simplified, but vehicles with low ground clearance cannot be loaded easily
Solution Approach 1:
The patent applies the dynamics principle by making the plateau's inclination adjustable rather than fixed. The support device allows the plateau to transition between inclined (for easy loading) and horizontal (for low ground clearance vehicles) positions dynamically, resolving the contradiction between loading ease and vehicle compatibility.
Solution Approach 2:
The patent changes the geometric parameter of the plateau's angle of inclination from a fixed value to a variable parameter. By adjusting the inclination angle through the support device, the system can adapt to different vehicle types, including those with low ground clearance, while maintaining ease of operation.
2Ease of operation
If the front end of the plateau is fixed at the rear loading opening level, then the plateau forms an inclined ramp, but vehicles with very low ground clearance face loading difficulties
Solution Approach 1:
The support device enables the front end of the plateau to move vertically, transforming the static inclined ramp into a dynamic structure. This allows the system to adapt its geometry to eliminate loading difficulties for low clearance vehicles while preserving loading convenience when needed.
Solution Approach 2:
The support device acts as an intermediary mechanism between the plateau and the box body, providing the necessary vertical movement capability. This mediator allows the plateau to achieve both inclined and horizontal positions, resolving the conflict between loading convenience and accessibility for low clearance vehicles.
3Ease of operation
If the plateau is extended out of the box body for loading, then vehicles can be loaded, but the transport security is reduced
Solution Approach 1:
The patent applies dynamics by making the plateau's position between extended (for loading) and retracted (for security) adjustable. The support device enables this dynamic positioning, allowing the system to provide both loading capability and transport security as needed.
Solution Approach 2:
The loading and transport functions are segmented into distinct positional states of the plateau. The plateau can be extended for loading operations and retracted for secure transport, with the support device facilitating transitions between these segmented functional states.
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
This design enables effortless loading and unloading of vehicles with low ground clearance and allows for the transportation of heavy or multiple vehicles discreetly within a closed box body, ensuring secure and efficient operations.
Implementation Method 1
at least one lifting element is present, through which the front end of the plateau can be lowered in an approximately vertical movement
Implementation Method 2
The rear end of the plateau can preferably be equipped with castors. As a result, the rear end of the plateau can be shifted a little backwards when the front end of the plateau is lowered. In addition, the castors at the rear end of the platform make it easier to slide the platform into the box body.
Implementation Method 3
the support device can be equipped with at least one gearwheel and can be mounted longitudinally displaceably via this gearwheel on at least one toothed rack arranged in the longitudinal direction of the box body

AI summary
A vehicle (10.2) for transporting at least one passenger car (12) has a closed box body (14.2) and a platform (20.2) which, in its transport position, is located inside the box body (14.2). From this transport position, the platform (20.2) can be moved into a loading position in which the rear end (26) of the platform (20.2) rests on the roadway (28) and the front end (30.2) of the platform (20.2) is secured in the area of the rear loading opening of the box body (14.2). The front end (30.2) of the platform (20.2) can be lowered approximately vertically by at least one lifting element (32.2) so that the front end (30.2) of the platform (20.2) also rests on the roadway (28).
