Height adjustable desktop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most work surfaces are stationary, failing to accommodate the health benefits of adjustable height, which can be impractical for individuals to replace entire desks, and existing height-adjustable desks may not provide sufficient ergonomic flexibility.
Innovation Solution
A height-adjustable desktop system comprising an upper work surface platform, a base platform, and a scissoring motion-based height adjustment mechanism with actuators and feedback sensors, allowing for precise vertical and horizontal adjustment of the keyboard tray to optimize ergonomic positioning without protruding outward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an entire desk is replaced with a height-adjustable desk, then height adjustability is achieved, but cost and space requirements increase
Solution Approach 1:
The invention divides the height adjustment function from the entire desk structure, creating a separate adjustable desktop unit that can be placed on top of an existing desk. This segmentation allows the height adjustment mechanism to be independent, reducing overall system complexity and cost while maintaining the adaptability benefit.
Solution Approach 2:
The adjustable desktop unit is designed to be universally compatible with existing desks and work surfaces. By making the adjustment mechanism independent and modular, it can be applied to various desk types without requiring complete desk replacement, thus achieving multi-functionality across different work environments.
2Ease of operation
If a stationary desk is used, then simplicity and cost-effectiveness are maintained, but ergonomic flexibility is insufficient
Solution Approach 1:
The invention transforms the static desk surface into a dynamic one by incorporating a height adjustment mechanism with movable components. The scissor-like linkage system allows the desktop to transition between different height positions, providing ergonomic flexibility while maintaining operational simplicity through automated or manual adjustment controls.
3Ease of operation
If the keyboard tray protrudes outward when adjusted, then ergonomic positioning is improved, but space requirements increase
Solution Approach 1:
The keyboard tray is designed to nest within or alongside the main desktop structure when not in use. The adjustment mechanism allows the tray to be positioned ergonomically when needed, then retracted or folded into the desktop's existing space, eliminating the need for additional horizontal space while maintaining ergonomic benefits during operation.
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
Enables users to adjust the work surface to various heights and positions, promoting ergonomic comfort, reducing back strain, and enhancing productivity by allowing seamless transitions between sitting and standing, with no pre-set locking points and increased load capacity.
Implementation Method 1
a height adjustment mechanism that in part includes two sets of two arms that connect at a pivot point along their lengths so that the arms move in a scissoring motion to raise and lower the upper work surface

AI summary
A height adjustable desktop includes an upper work surface platform, and a base platform, which configured to rest on an existing desk, platform, surface, or table. The height adjustable desktop further includes a height adjustment mechanism that includes two sets of two arms that connect at pivot points along their lengths so that the arms configured to move in a scissoring motion to raise and lower the upper work surface platform. The height adjustable desktop also includes two actuators that apply a force to the two sets of two arms, the actuators each containing feedback sensors that provide data regarding the current position and distance each actuator has extended, retracted or moved.
