Height-Adjustable Table Strut Articulation for Simplified Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable tables require complex mechanisms for height adjustment and often compromise on space-saving transportability due to intricate assembly processes.
Innovation Solution
The design simplifies height adjustment by directly connecting pairs of struts with articulated joints and allowing adjusting struts to be slidably mounted on the table base and top, eliminating the need for a connecting device and enabling straightforward attachment of a drive mechanism, such as an actuator on the table top support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting device and connection strut are used to synchronize the movement sequences of the two pairs of struts, then the height adjustment mechanism is functional, but the device complexity increases and assembly becomes more complicated
Solution Approach 1:
The patent merges the synchronization function into the strut structure itself by articulating the first support strut to both the second support strut and the second adjusting strut through joints. This integration eliminates the need for separate connecting devices and connection struts, reducing device complexity while maintaining synchronized movement of the strut pairs during height adjustment.
Solution Approach 2:
The support struts and adjusting struts are designed to serve multiple functions simultaneously. The first support strut not only provides structural support but also articulates to both the second support strut and the second adjusting strut, enabling synchronization and height adjustment through a single component rather than requiring separate dedicated components for each function.
2Stability of the object's composition
If the adjusting struts are rigidly fixed to the table base and top support, then the structure is stable, but the height adjustment range and flexibility are limited
Solution Approach 1:
The patent applies dynamic mounting where the first adjusting strut is slidably mounted on the table base and the second adjusting strut is slidably mounted on the table top support. This allows the adjusting struts to move relative to the base and support during height adjustment, providing continuous adaptability across a range of heights while maintaining structural stability when locked in position.
Solution Approach 2:
The adjusting struts are divided into segments that can slide relative to each other and to the mounting surfaces. The slidable mounting creates segmented, movable connections rather than rigid fixed connections, enabling the structure to adapt to different height requirements while maintaining stability through the joint connections.
3Ease of operation
If multiple gas pressure springs are used to set the desired height, then the height adjustment capability is achieved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent extracts the height setting function from complex multi-spring mechanisms and implements it through the slidable mounting system of the adjusting struts. The simplified mechanism relies on the mechanical interaction between the slidable struts and joints rather than multiple gas pressure springs, reducing assembly complexity while maintaining the ability to set and maintain desired heights.
