Mobile workstation with adjustable height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile workstations lack sufficient vertical adjustment range and stability, often becoming shaky and imbalanced during height changes, which can disrupt the contents of the workstation surface and computer system.
Innovation Solution
A mobile workstation with a mechanical adjustable height system featuring telescopic shaft segments and pulley assemblies, allowing for a vertical adjustment range of over 25 inches, with a biasing element and lock mechanism for secure positioning, ensuring smooth and stable height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vertical adjustment is provided in mobile workstations, then user comfort and adaptability are improved, but the workstation becomes shaky and mis-balanced during height changes
Solution Approach 1:
The adjustment shaft is divided into multiple telescopic segments (first, second, and third shaft segments) that can extend and retract independently. This segmentation allows the shaft to achieve a broad vertical adjustment range while maintaining structural integrity and balance during height changes, preventing the workstation from becoming shaky or mis-balanced.
Solution Approach 2:
A biasing element (spring) is incorporated into the adjustment mechanism to provide counterbalancing force during height adjustments. This counterweight mechanism offsets the weight of the top assembly, ensuring smooth and stable raising and lowering while preventing shaking and maintaining workstation stability throughout the adjustment range.
2Adaptability or versatility
If vertical adjustment mechanism is added to mobile workstation, then adjustment range is improved, but device complexity increases
Solution Approach 1:
The adjustment shaft employs a telescopic design where the first, second, and third shaft segments are nested within each other. This nesting arrangement allows for a broad adjustment range to be achieved within a compact structure, minimizing the overall space required while providing extensive height variability. The segments telescope in and out smoothly to extend the adjustment range without proportionally increasing the retracted height.

AI summary
A mobile workstation with adjustable height of the present disclosure may comprise a top assembly, an adjustment assembly, and a bottom assembly. Adjustment assembly may comprise telescopically engaged segments. One or more pulleys or pulley assemblies may be disposed within one or more of the segments to allow for withdrawing and retracting segments from one another at the same rate. Actuation of the raising or lowering of the overall height of the mobile workstation may be realized through either a manual actuation or an electronic element such as a linear actuator.
