Height Adjustable Floor Guide with Tiered Support Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing height adjusting system for motor vehicle load compartments lacks sufficient physical support, causing the loading floor to bend and bow under heavy objects, leading to instability.
Innovation Solution
A height adjusting device with a guide system and tiered support elements, featuring dynamic and fixed plates with interlocking profiles, provides additional support and stability by allowing the loading floor to be adjusted in multiple height positions while preventing interference during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the loading floor is made height adjustable to vary vertical space, then the versatility of the load compartment is improved, but the structural stability deteriorates due to bending and bowing under heavy objects
Solution Approach 1:
The support system is segmented into multiple discrete support elements positioned at different locations beneath the loading floor. Each support element provides independent stabilization, collectively preventing bending and bowing while allowing height adjustment. The segmentation of support functions across multiple points maintains structural integrity during vertical movement.
Solution Approach 2:
The solution introduces support elements in the vertical dimension beneath the loading floor to counteract the vertical movement and deformation. By adding support in the downward direction (another dimension relative to the loading floor surface), the system prevents bending and bowing while maintaining height adjustability in the upward direction.
2Stability of the object's composition
If support elements are added to prevent bending and bowing, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The support elements are designed to automatically engage and disengage based on the loading floor's position and load conditions. The system self-regulates without requiring external control mechanisms, reducing complexity while maintaining structural stability. The support elements activate only when needed to prevent bending, rather than requiring continuous active management.
3Stability of the object's composition
If the loading floor is supported at multiple points, then the structural stability is improved, but the ease of operation deteriorates due to potential interference during movement
Solution Approach 1:
The support elements are designed with dynamic characteristics that allow them to adapt to the loading floor's movement. The support system transitions between engaged and disengaged states based on the floor's position, enabling smooth operation while maintaining stability when needed. This dynamic behavior prevents interference during height adjustment.

AI summary
A motor vehicle, including: a loading floor; a height adjusting device with a guide on which the loading floor is pivotably mounted and movable in a substantially vertical direction and can be mounted in at least two height positions; one or more tiered support elements for supporting the loading floor in the at least two height positions; where the guide includes a first guideway for moving the floor towards the top of the guide and a second guideway for moving the floor towards the bottom of the guide; where the first guideway is configured such that exerting a backward longitudinal pulling force on the loading floor results in movement of the loading floor from a lower height position to an upper height position; and a set of corresponding features positioned beneath the loading floor for providing physical support and stability in the at least two height positions.
