Motorized, height-adjustable desktop system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable desktop systems require manual effort to change positions from sitting to standing, which can be cumbersome, especially when dealing with heavy computer equipment.
Innovation Solution
A motorized desktop system with a scissor assembly and linear actuator mechanism that allows for automatic height adjustment using a switch-actuated elevation mechanism, enabling easy transition between sitting and standing positions without manual lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual spring-assisted lift mechanism is used, then the system structure is simple, but the user must manually lift heavy computer equipment which is cumbersome and difficult to operate
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 automatically adjusts the desktop height without requiring manual lifting, thereby improving ease of operation while accepting increased device complexity through the addition of motorized components and control systems.
2Stability of the object's composition
If the desktop is made heavy to support computer equipment, then the stability is improved, but the manual adjustment becomes more difficult
Solution Approach 1:
The patent resolves this contradiction by replacing manual mechanical adjustment with an electric motor-driven system. The linear actuator can easily lift and position the heavy stable desktop assembly, maintaining stability while eliminating the difficulty of manual adjustment. The motorized system provides controlled elevation and lowering of the heavy load without requiring user strength.
3Ease of operation
If a motorized elevation mechanism is introduced, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies mechanics substitution by replacing complex manual mechanical adjustment systems with a more compact motorized linear actuator system. While this does increase device complexity, the trade-off is justified by the significant improvement in ease of operation, allowing users to effortlessly adjust height with the push of a button rather than manually lifting heavy equipment.
Solution Approach 2:
The motorized elevation mechanism enables the desktop system to adjust its own height automatically without human physical intervention. The integrated motor and control system allows the furniture to serve itself in the height adjustment function, improving operational ease while consolidating control functions within the system.

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.
