Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting platforms face challenges in efficiently adjusting to loads with varying ground clearances and chassis types, requiring significant time and energy to reposition support devices, and there is a need for a cost-effective and reliable solution that allows independent height adjustment of support devices.
Innovation Solution
A support device with a hollow bushing that can be continuously adjusted and a support element that can be adjusted in a stepwise manner relative to the bushing, using a screwing and insertion mechanism, allowing for precise positioning and adaptation to different vehicle heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support device is moved along the lifting axis to accommodate different ground clearances, then the lifting platform can handle vehicles with varying heights, but the adjustment time and energy consumption increase significantly
Solution Approach 1:
The support device incorporates a hollow bushing with an external thread that allows continuous adjustment along the lifting axis, enabling the support element to dynamically adapt to different ground clearances without requiring time-consuming repositioning operations
Solution Approach 2:
The support device is divided into separable components (hollow bushing, support element, stop element) that can be independently adjusted and positioned, allowing efficient adaptation to various vehicle heights through modular assembly and disassembly
2Adaptability or versatility
If the support device is moved along the lifting axis to accommodate different ground clearances, then the lifting platform can handle vehicles with varying heights, but the energy consumption increases
Solution Approach 1:
The threaded hollow bushing enables continuous, fine-adjustment movement along the lifting axis with minimal energy input, allowing the support element to dynamically adapt to different ground clearances without requiring large energy-consuming repositioning operations
Solution Approach 2:
The support device is designed to be self-adjusting through the threaded mechanism, where the hollow bushing can be rotated to move the support element along the lifting axis without requiring external power or energy-intensive actuation systems
3Manufacturing precision
If the hollow bushing is made with an external thread for continuous adjustment, then the support device can be precisely positioned, but the manufacturing complexity increases
Solution Approach 1:
The hollow bushing serves multiple functions simultaneously: it provides continuous adjustment through the external thread, supports the support element, and incorporates the stop element for positioning control, thereby achieving precise positioning without proportionally increasing structural complexity
Solution Approach 2:
The support element is inserted into the hollow bushing, with the stop element positioned within the hollow bushing's cavity, creating a nested arrangement where multiple functional components are integrated within a compact structure, minimizing overall complexity while maintaining precision
4Adaptability or versatility
If the support element can be adjusted in stepwise manner relative to the hollow bushing, then the device can adapt to different vehicle heights, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into two distinct functions: continuous adjustment via the threaded hollow bushing and stepwise adjustment via the stop element, allowing the device to adapt to different vehicle heights through simple, separate operations rather than a complex integrated mechanism
Solution Approach 2:
The stepwise adjustment mechanism operates through periodic rotational movements of the support element relative to the hollow bushing, where each rotation engages the stop element at discrete positions, providing adjustable height in simple, repeated motions without requiring complex continuous control systems

Function Achieved in This Case
Enables rapid and efficient adjustment of support devices to accommodate vehicles with varying ground clearances, reducing adjustment time and energy consumption while maintaining reliability and cost-effectiveness.
Implementation Method 1
the outer side of the hollow bushing may have an external thread, by means of which the hollow bushing is fastenable to the lifting platform in a continuously adjustable manner with a screwing movement
Implementation Method 2
A stop element arranged in the cavity is designed in such a way that an insertion depth of the support element in the cavity can be set in a stepwise manner, wherein the insertion depth depends on a relative rotational position between the support element and the hollow bushing about the insertion axis
