Telescopic column with stabilizing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telescopic columns in height-adjustable furniture face instability due to the increasing distance between stabilization points when extended, limiting the stroke and stability, especially in long-term use.
Innovation Solution
A telescopic column design featuring a combination of static and mobile stabilizing devices, where static devices provide supportive and bearing functions, and the mobile device is axially movable to enhance stability throughout the column's stroke, with static devices arranged radially between telescopic tubes and the mobile device positioned within the inner space to adjust support based on extension or retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the distance between stabilizing points is increased to provide lateral support, then the stability of the telescopic column is improved, but the total stroke of the telescopic tubes is limited
Solution Approach 1:
The patent introduces a mobile stabilizing device that can move axially along with the telescopic tubes, transforming the static stabilizing system into a dynamic one. This allows the stabilizing points to maintain their relative positions to the tubes while the entire system can extend and retract, resolving the contradiction between stability and stroke length
Solution Approach 2:
The stabilizing system is divided into multiple independent stabilizing devices distributed at different axial positions. Each stabilizing device provides localized stabilization, allowing the column to maintain stability across varying lengths without limiting the overall stroke
2Stability of the object's composition
If stabilizing means are statically attached to provide lateral support, then the construction is stabilized, but the bearing function is insufficient for long-term height adjustment
Solution Approach 1:
The stabilizing devices are designed to perform multiple functions simultaneously: providing lateral stabilization and serving as bearing surfaces for the telescopic tubes during height adjustment. This multi-functionality ensures both stability and reliable bearing capability for long-term use
Solution Approach 2:
The stabilizing function and bearing function are merged into a single integrated stabilizing device. The stabilizing means are designed with bearing surfaces that can support axial loads while providing lateral stability, eliminating the need for separate bearing mechanisms
