Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting tables require manual effort to expand the upper platform from the lowest position due to negligible lifting force from elastic elements, resulting in a laborious and poor user experience.
Innovation Solution
Incorporating sliding components connected with elastic elements that apply an upward lifting force to the lifting component, allowing the upper platform to be easily expanded by the elastic force when folded to the lowest position, with a simple structure and low manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the elastic elements are positioned horizontally when the upper and lower platforms are folded to the lowest position to minimize folded thickness, then the folded thickness is reduced, but the lifting force applied to the upper platform becomes negligible requiring manual effort to expand
Solution Approach 1:
The patent introduces a sliding component that moves horizontally along the lower platform, converting the vertical lifting function into a horizontal sliding motion. This dimensional change allows the elastic element to remain horizontal (maintaining minimal folded thickness) while still providing lifting force through the mechanical advantage of the sliding mechanism.
Solution Approach 2:
The sliding component acts as an intermediary between the elastic element and the upper platform. It transfers the horizontal elastic force into vertical lifting motion, enabling the system to maintain both compact folded thickness and effective lifting capability without requiring manual intervention.
2Force
If the elastic elements are made stronger to provide sufficient lifting force when the upper platform is at the lowest position, then the lifting force is improved, but the folded thickness increases due to the larger amplitude required for the elastic elements
Solution Approach 1:
By introducing horizontal sliding motion as an intermediate step, the system converts what would require large vertical elastic element amplitude into small horizontal displacement. This allows the elastic elements to remain compact (minimal folded thickness) while still generating sufficient lifting force through the sliding mechanism's mechanical advantage.
Solution Approach 2:
The patent changes the operational parameters of the elastic elements from large vertical amplitude movements to small horizontal sliding movements. This parameter transformation enables the elastic elements to maintain a compact folded state while still providing the necessary lifting force through the modified motion path.
3Device complexity
If manual effort is required to separate the upper platform from the lower platform when folded to the lowest position, then the structure can be simplified, but the user experience deteriorates due to the laborious operation
Solution Approach 1:
The sliding component enables the system to serve itself by automatically providing the lifting force needed to expand the upper platform. The elastic element-driven sliding mechanism self-activates to separate the platforms without requiring manual intervention, maintaining structural simplicity while dramatically improving ease of operation and user experience.

Function Achieved in This Case
The lifting table effectively provides an upward force for the upper platform to rise quickly and easily from the lowest position, enhancing user experience and simplifying operation.
Implementation Method 1
One end of the elastic element is hinged with the first or second strut, while the other end thereof is hinged on the upper or lower platform... the sliding component slides with the aid of the elastic force of the elastic element
