Foldable height adjustable table stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foldable height adjustable table stands suffer from structural instability and reduced usage strength due to their half-covering structure, leading to vibrations and discomfort during long-term use.
Innovation Solution
A foldable height adjustable table stand design featuring a U-shaped cross-section for the pivoting stabilizers to contact the support crossbar with three surfaces, combined with a folding transmission mechanism including a driving motor and connecting rods, enhances stability and strength by preventing shake and facilitating smooth folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a half-covering support cover structure is used to connect the crossbar, then the device complexity is reduced, but the stability and structural integrity deteriorate due to vibration and reduced using strength
Solution Approach 1:
The patent merges the support cover with the crossbar to form an integrated U-shaped structure. The support cover is extended to cover both sides of the crossbar completely, eliminating the gap present in half-covering designs. This integration strengthens the overall structure, prevents vibration, and improves stability while maintaining manufacturing simplicity.
2Ease of manufacture
If a half-covering support cover structure is used, then the ease of manufacture is improved, but the using strength deteriorates due to reduced contact area with the crossbar
Solution Approach 1:
The support cover is designed as a U-shaped structure that completely encompasses the crossbar, merging these components into a unified load-bearing assembly. This increases the contact area between the support cover and crossbar, distributing forces more effectively and significantly improving the using strength without complicating the manufacturing process.
3Device complexity
If the support cover is connected with two sides of the crossbar with a half-covering shape, then the device complexity is reduced, but vibration increases resulting in structural instability
Solution Approach 1:
By extending the support cover to completely enclose the crossbar in a U-shaped configuration, the patent eliminates the gaps that allow vibration in half-covering designs. The merged structure creates continuous contact surfaces that dampen vibrations and prevent structural instability, all while maintaining a simple, manufacturable design.

AI summary
A table stand includes a first pivoting stabilizer, a second pivoting stabilizer, a first height adjustable pole connected to the first pivoting stabilizer, a second height adjustable pole connected to the second pivoting stabilizer, a folding transmission mechanism separately connected to the first height adjustable pole and the second height adjustable pole, and a support crossbar connected to the folding transmission mechanism. The first pivoting stabilizer and the second pivoting stabilizer are movably connected to two ends of the support crossbar. Each of the first pivoting stabilizer and the second pivoting stabilizer includes a first blocking edge, a second blocking edge, and a first shaft sequentially passing through the first blocking edge and the second blocking edge. The support crossbar is disposed between the first blocking edge and the second blocking edge.
