Motor Vehicle Loading Floor Height Adjustment Guideway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjusting devices for motor vehicle loading floors require significant force and complexity to move the loading floor from a lower to an upper position, making it difficult to efficiently adjust the height.
Innovation Solution
A dual guideway system is implemented, where the loading floor is mounted on a guide with a first guideway for vertical movement upwards and a second guideway for downwards movement, allowing spatial and kinematic separation of movements to facilitate easier handling, with support elements and guide bolts ensuring secure positioning in multiple height positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single guideway system is used for moving the loading floor vertically, then the structure is simpler, but significant force is required and the operation becomes complex
Solution Approach 1:
The guideway system is segmented into two separate guideways: a first guideway for upward movement and a second guideway for downward movement. This segmentation allows each guideway to be optimized for its specific direction of movement, reducing the force required and simplifying the overall operation while maintaining structural efficiency
2Force
If the loading floor is moved vertically with a single guideway, then the structure is more compact, but the force expenditure increases significantly
Solution Approach 1:
The guideway system is divided into two separate guideways, each optimized for a specific direction of movement. The first guideway facilitates upward movement with reduced force requirements, while the second guideway handles downward movement efficiently. This segmentation reduces the force expenditure compared to a single guideway system
Solution Approach 2:
The guideways are arranged in a spatially separated configuration, utilizing three-dimensional space efficiently. The first guideway is positioned for upward movement while the second guideway is positioned for downward movement, creating a spatial separation that reduces force requirements without significantly increasing structural complexity
3Ease of operation
If spatial separation of guideways is implemented, then movement handling is simplified, but the device structure becomes more complex
Solution Approach 1:
The guideways are arranged in a spatially separated configuration in three-dimensional space, with the first guideway positioned for upward movement and the second guideway positioned for downward movement. This spatial arrangement simplifies movement handling by providing dedicated paths for each direction while maintaining a compact overall structure that does not excessively increase device complexity

AI summary
A motor vehicle includes, but is not limited to a loading floor, a height adjusting device for the loading floor with a guide, on which the loading floor is mounted pivotably on a front end portion about a pivot axis and movably for a movement with a component in vertical direction and the loading floor with the guide can be mounted in at least two different height positions, at least two support elements formed in a different vertical orientation for supporting a rear end portion of the loading floor in the at least two different height positions. The guide includes, but is not limited to a first guideway for moving the front end portion towards the top and a second guideway for moving the front end portion towards the bottom and the first and second guideway are formed spatially separated on the guide.
