Height adjustable desktop work surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks are not easily convertible to height-adjustable sit-to-stand desks without requiring substantial modification, which can render them unsuitable for their original use.
Innovation Solution
A height-adjustable desktop system with a foot assembly and linkage assembly that allows vertical adjustment of the work surface, incorporating clamping members for stability and a biasing mechanism to maintain a horizontal orientation, enabling conversion of fixed-height desks to sit-to-stand configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed or height adjustable computer mount with clamping apparatus is used to secure the monitor to the work surface, then the monitor can be positioned at appropriate heights for standing or alternating use, but the existing desktop must be modified by drilling holes or removing edge sections, requiring substantial investment and rendering the desktop unsuitable for its original use
Solution Approach 1:
A vertical riser assembly acts as an intermediary structure between the existing desktop and the computer monitor. The riser includes a base portion that contacts the desktop surface and an upright portion that supports the monitor, allowing height adjustment without modifying the desktop itself. This mediator approach enables the monitor to be positioned at appropriate heights for standing or alternating use while preserving the original desktop.
Solution Approach 2:
The computer mount is divided into separate functional components: a base portion that interfaces with the desktop, an upright portion that provides vertical support, and a monitor-supporting component. This segmentation allows the mount to be adjusted and reconfigured without affecting the desktop, enabling height adjustability while maintaining desktop versatility for its original use.
2Reliability
If clamping apparatus such as edge clamps or grommet mounts are used to fix the riser to the work surface, then the monitor can be securely mounted, but the desktop must be permanently modified by drilling holes or removing edge sections
Solution Approach 1:
The base portion of the vertical riser serves as an intermediary that distributes mounting forces across a larger area of the desktop surface rather than concentrating stress at drill holes or edge sections. This approach secures the monitor while preserving the desktop's structural integrity and avoiding permanent modifications.
Solution Approach 2:
Instead of modifying the desktop to accommodate mounting hardware (drilling holes, removing edges), the invention inverts the approach by having the mounting hardware adapt to the existing desktop surface. The base portion is designed to contact and secure to the desktop as-is, reversing the traditional approach of forcing the desktop to conform to mounting requirements.

AI summary
In one example, a height adjustable desktop system is described that can include a work surface, a foot assembly and a linkage assembly that adjustably connects the work surface to the foot assembly allowing vertical adjustment of the work surface. The linkage assembly can include a pair of adjustment assemblies, each having a transverse linkage that maintains the work surface in a horizontal orientation as the work surface is elevated or lowered. A biasing mechanism, such as an extension spring or a torsion spring, biases the work surface toward the elevated position.
