Folding Table with Adjustable Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding tables face challenges in quick height adjustment and stability, particularly when used outdoors, due to the need to simultaneously press and hold buttons on telescopic legs, leading to wobbling and instability.
Innovation Solution
A foldable leg frame with first and second adjustment bars that flip up and down relative to their respective table legs, supported by hinged first and second support bars that rotate into a straight-line state with a locking mechanism to ensure stability, allowing quick height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopic tubes are used to adjust table leg height, then height adjustment is achieved, but the adjustment process requires pressing and holding buttons on two table legs simultaneously, making it impossible to achieve quick adjustments
Solution Approach 1:
The height adjustment mechanism is divided into independent segments: the adjustment bar can be operated independently on each table leg, and the support bar provides additional independent support. This segmentation allows one-legged adjustment without requiring simultaneous operation of multiple legs, significantly reducing adjustment time and operational complexity.
2Ease of operation
If telescopic rods are used for height adjustment, then the rod extends into the leg tube to adjust height, but there is inevitably a gap between the telescopic rod and the leg tube, leading to wobbling
Solution Approach 1:
The support bar acts as an intermediary element between the adjustment bar and the ground. It provides additional support and stabilization, filling the functional gap left by the telescopic rod-leg tube clearance. The support bar connects to the adjustment bar and extends to the ground, creating a triangular support structure that eliminates wobbling and enhances table stability during and after height adjustment.
3Device complexity
If telescopic rods are used for height adjustment, then the rod cannot be additionally supported by a support rod, but since outdoor tables frequently bear weight, the resulting wobbling inevitably affects the stability of the tabletop
Solution Approach 1:
The support bar is merged with the adjustment bar to form an integrated height adjustment and stabilization system. The support bar is connected to the adjustment bar, combining the height adjustment function with the stability support function into a single coordinated mechanism. This merging allows the system to maintain simplicity while providing enhanced stability under outdoor loading conditions.

AI summary
The present invention discloses a folding table that can be quickly increased in height, including a first table leg and a second table leg arranged oppositely. The bottom end of the first table leg is provided with a first adjustment bar that can flip to achieve height adjustment, and the bottom end of the second table leg is provided with a second adjustment bar that can flip to achieve height adjustment. By simply flipping the first adjustment bar and the second adjustment bar outward simultaneously to a vertical state, the foldable leg frame can quickly increase in height. Additionally, by providing a locking mechanism, the stability of the folding table is further enhanced.
