Desk-mounted lifting platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior desk-mounted lifting platforms have a complicated structure that provides weak lifting force at the lowest position and poor user experience due to the need for additional springs and cumbersome disassembly of keyboard trays.
Innovation Solution
A desk-mounted lifting platform with an X-shaped first and second lifting arm configuration, a gas spring between the upper and lower supports, and an obliquely intersecting axis to enhance lifting force, along with a detachable keyboard support that can be assembled/disassembled without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a gas spring is disposed horizontally in the lifting workbench, then the lifting force is applied to the workbench, but the lifting force becomes weak when the lifting platform is located in or lowered to the lowest position
Solution Approach 1:
The gas spring axis is arranged obliquely rather than horizontally, changing the spatial dimension and orientation of the force application. This oblique arrangement allows the gas spring to maintain effective lifting force throughout the full range of motion, including at the lowest position where horizontal springs fail.
2Force
If an additional spring is arranged on the bottom of the plate to provide lifting force at the lowest position, then the lifting force at the lowest position is improved, but the structure becomes complicated
Solution Approach 1:
The patent extracts and eliminates the need for additional springs by repositioning the single gas spring to an oblique arrangement. This removes the complexity of multiple spring components while maintaining the necessary lifting force at all positions, including the lowest position.
3Strength
If a screwed connection is used to connect the keyboard tray to the workbench, then the connection is secure, but the disassembly requires hand tools and takes long time
Solution Approach 1:
The patent replaces the traditional screwed mechanical connection with a quick-release mechanism that uses a releasing component to detach the keyboard tray. This substitution maintains secure connection during use while enabling tool-free, rapid disassembly by simply operating the releasing component.
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
The platform offers a simple structure with strong lifting force at the lowest position and improved user experience through balanced gas spring action and tool-free keyboard tray assembly/disassembly.
Implementation Method 1
A gas spring is arranged between the upper support and the lower support. The gas spring is used for providing a lifting force to lift the upper support
Implementation Method 2
A first lifting arm and a second lifting arm are X-shaped and hinged at an intersection thereof. An upper end of the first lifting arm is hinged with the upper support. A lower end of the first lifting arm is slidably fitted on the lower support
Implementation Method 3
an axis of the gas spring intersects a working plane of the workbench obliquely
