Desktop Riser Clamping Assembly for Non-Destructive Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks are not easily convertible to height-adjustable sit-to-stand desks without requiring substantial modifications, such as drilling holes or removing edge sections, 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, using parallel and transverse linkages to maintain a horizontal orientation and include a clamping mechanism for stability, enabling conversion of fixed height desks to sit-to-stand configurations without permanent modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a clamping apparatus is used to secure the riser 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
Solution Approach 1:
The patent introduces a riser assembly as an intermediary component between the work surface and the monitor/keyboard. This riser can be secured using clamping apparatus that attaches to the edges of the desktop without drilling holes, thereby achieving height adjustability while avoiding damage to the desktop surface.
Solution Approach 2:
The system is divided into separate functional components: the work surface, the riser assembly, and the monitor/keyboard mounting. This segmentation allows the riser to be independently positioned and secured at different heights without modifying the original work surface, thus enabling height adjustment while preserving the desktop integrity.
2Reliability
If the desktop is modified by drilling holes or removing edge sections to secure the riser, then the riser can be firmly attached, but the desktop is rendered unsuitable for its original intended use or other uses
Solution Approach 1:
The clamping apparatus serves as a mediator that provides firm attachment of the riser to the desktop edges without penetrating or removing material. This maintains the desktop's original integrity and versatility while achieving reliable riser attachment through the clamping mechanism's friction and mechanical grip.
3Ease of operation
If a vertical riser mount is used for standing use, then computer use can be performed while standing to prevent back strain, but the monitor must be fixed to the work surface to avoid tipping
Solution Approach 1:
The patent combines multiple functions into the riser assembly: it provides vertical elevation for standing use, serves as the mounting structure for the monitor and keyboard, and includes the clamping apparatus for attachment to the desktop. This integration reduces overall system complexity compared to having separate components for each function.

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.
