Systems and methods for automatically directing a height adjustable desk based on a plurality of sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact, motorized, and height-adjustable desktop system that allows users to easily transition between sitting and standing positions without manual adjustment, particularly for smaller workspaces, and existing manual lift mechanisms are cumbersome and require manual effort.
Innovation Solution
A compact motorized, software-controlled desktop system with a trapezoid-shaped base, an electric motor, and a keyboard tray that can be adjusted in height using a push-button mechanism, allowing for ergonomic adjustments while maintaining a minimalistic and space-saving design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual spring-assisted lift mechanism is used, then the structure is simple, but the user must manually lift the heavy desktop which reduces ease of operation
Solution Approach 1:
The patent replaces the manual spring-assisted mechanical lift mechanism with an electric motor system. The motorized height adjustment mechanism includes a motor coupled to a lead screw or rack and pinion system, which automatically adjusts the keyboard tray and monitor assembly height without requiring manual lifting effort. This substitution of mechanical manual operation with an electric automated system directly resolves the contradiction by improving ease of operation while accepting increased device complexity.
2Area of stationary object
If the base is made compact to save space, then the footprint is reduced, but the structure must support heavy loads which increases design difficulty
Solution Approach 1:
The patent employs composite construction for the base structure, combining steel sheet metal with wooden top surfaces and internal reinforcement elements. The base includes a steel frame with cross-bracing and reinforcing ribs that provide high strength-to-weight ratio, enabling the compact footprint to support the heavy load of the desktop, computer equipment, and adjustment mechanisms. This composite approach allows the base to maintain small footprint while achieving the necessary load-bearing capacity.
3Ease of operation
If the desktop system is made height-adjustable to improve ergonomics, then user comfort increases, but the device complexity increases due to additional mechanisms
Solution Approach 1:
The patent integrates multiple functions into a single height adjustment mechanism. The same motorized system that raises and lowers the keyboard tray also adjusts the monitor assembly height through a coupled mechanism. Additionally, the system includes preset memory functions and automatic detection capabilities that manage multiple adjustment parameters through a unified control interface. This multi-functionality approach allows the system to provide comprehensive ergonomic adaptability while consolidating control complexity into a single integrated system rather than separate mechanisms for each component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides easy, electric height adjustment, is durable, and ergonomic, reducing user fatigue and accommodating various monitor sizes with tilt and swivel adjustments, suitable for smaller workspaces.
Implementation Method 1
An electric motor allows the keyboard tray and monitor mount assembly to move up and down (away and toward the base plate)
Data Source
AI summary
Systems and methods for adjusting position and/or orientation of a height adjustable desk are disclosed. The system receives data from one or more sensors, comprising sit and stand periods associated with a user of the height adjustable desk. The system further calculates a physical condition profile for the user, based on a pre-configured set of rules obtained by a network-connected health application. The physical condition profile is based on the sit and stand periods associated with the user. Further, the system creates a sit and stand schedule for the user based on the calculated physical condition profile and transmits a signal to an electric motor connected with the height adjustable desk, to adjust the height of height adjustable desk according to the sit and stand schedule.
