Table height adjustment system and method of using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table arrangements lack efficient mechanisms for quick and safe height adjustment, which can affect user comfort and safety, especially in office settings where tables need to accommodate both sitting and standing positions without damaging adjacent structures.
Innovation Solution
A table arrangement with an actuator and controller system that allows for automatic height adjustment between pre-set positions, using a manipulatable actuator member to store and recall sitting and standing heights, and includes safety features to prevent the tabletop from moving beyond minimum and maximum limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual height adjustment mechanisms are used, then device complexity is reduced, but adjustment speed and user comfort deteriorate
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated actuator system controlled by a controller that receives input from a sensor. The sensor detects when the tabletop reaches predetermined heights, and the actuator automatically adjusts the tabletop height, eliminating the need for manual operation and significantly increasing adjustment speed.
Solution Approach 2:
The system performs self-service through automatic height adjustment. The sensor continuously monitors the tabletop position and automatically triggers the actuator to adjust height when predetermined levels are reached, without requiring user intervention. This enables the system to service itself and maintains optimal height settings automatically.
2Adaptability or versatility
If full range height adjustment is allowed, then adaptability is improved, but safety and risk of damage worsen
Solution Approach 1:
The system performs preliminary action by pre-setting predetermined height positions before operation. The sensor is programmed with specific height thresholds, and the actuator automatically stops adjustment when these predetermined levels are reached. This prevents the tabletop from moving beyond safe limits and potentially damaging adjacent structures while still providing adequate adaptability for different working conditions.
3Productivity
If automatic height adjustment is implemented, then productivity is improved, but device complexity worsens
Solution Approach 1:
The system implements feedback through a sensor that continuously monitors the tabletop height and provides information to the controller. When the sensor detects that a predetermined height position has been reached, it sends a signal to the controller, which then stops the actuator. This closed-loop feedback mechanism enables automatic height adjustment, improving workplace productivity by eliminating manual intervention while keeping the control system relatively simple through direct sensor-actuator coupling.

AI summary
A table arrangement includes a height adjustment mechanisms for movement of one or more height adjustable tabletops. When more than one tabletop is present, each of the tabletops can be independently moveable. Embodiments of the table arrangement can be configured so that a user can manipulate an actuation mechanism to have the tabletop automatically moved to a pre-selected position without the user having to manually control the actuation mechanism to cause the tabletop to move to that pre-selected position.
