Solution Overview

Problem

Conventional workstations have fixed desk heights, which do not accommodate user preferences for height adjustments and can narrow the space under the desk, limiting flexibility and comfort.

Innovation Solution

A workstation with a pneumatic height-adjustable desk system, where pneumatic devices connected to the partitions allow the desk board to be lifted and lowered synchronously, using a synchronizing device to maintain stability and prevent tilting, while enlarging the space underneath.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional fixed-height desk is used, then the structure is simple and stable, but the desk height cannot be adjusted to accommodate different user needs

Engineering Contradiction:

Improvedesk height adjustabilityVSAvoiddesk structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The desk transitions from a static fixed-height structure to a dynamic height-adjustable structure by integrating pneumatic lifting devices that enable the desk board to move between different height positions, allowing the system to adapt to various user needs while maintaining structural integrity through controlled movement mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Pneumatic lifting devices are incorporated into the desk structure to provide height adjustment capability. These pneumatic mechanisms enable smooth elevation and lowering of the desk board, offering ergonomic flexibility without requiring complex mechanical linkages or manual adjustment systems

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Ease of operation

If multiple pneumatic devices are used to lift the desk board, then the desk board can be lifted smoothly, but the devices may move asynchronously causing instability

Engineering Contradiction:

Improvedesk board lifting smoothnessVSAvoiddesk board stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

A synchronizing device is integrated into the system that monitors and coordinates the operation of multiple pneumatic lifting devices. This feedback mechanism ensures that all pneumatic actuators move in unison, maintaining the desk board's horizontal stability during height adjustment and preventing tilting or uneven positioning

Inventive Principle:

Principle #23Feedback
