Motorized Desktop Stand with Switch-Actuated Linear Actuator Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable desktop systems require manual adjustment, which can be cumbersome and labor-intensive, especially when heavy computer equipment is present.
Innovation Solution
A motorized desktop system with a scissor assembly and linear actuator mechanism, powered by a motor, allows for automatic adjustment of desktop height through a switch-actuated elevation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual spring-assisted lift mechanism is used, then the system allows height adjustment, but the user must manually lift heavy computer equipment which increases labor intensity
Solution Approach 1:
The patent replaces the manual spring-assisted mechanical lift mechanism with an electric motor-driven linear actuator system. The motorized elevation mechanism eliminates the need for manual lifting force while providing automated height adjustment, directly resolving the contradiction between ease of operation and required user force.
Solution Approach 2:
The motorized system enables the desktop to adjust its own height automatically without requiring user physical intervention. The switch-actuated elevation mechanism allows the system to serve itself by transitioning between sitting and standing positions autonomously, reducing labor intensity to minimal button pressing.
2Extent of automation
If a motorized elevation mechanism is implemented, then automatic height adjustment is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the motorized elevation system into distinct functional modules: a linear actuator for vertical movement, a scissor assembly for mechanical advantage and stability, and a simple switch control interface. This segmentation allows each component to perform its specific function efficiently while keeping the overall system manageable and maintainable despite the added automation.

AI summary
A motorized desktop stand unit having a main surface assembly designed to accommodate a monitor or laptop and a secondary surface assembly designed to accommodate a keyboard. The desktop stand unit also has a frame assembly having an upper frame and a lower frame. An elevation mechanism is provided between the upper frame and lower frame. A switch provided in the main surface assembly, when actuated, causes the elevation mechanism to adjust the space between the upper frame and lower frames, changing the height of the main surface assembly.
