Height-adjustable table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjustable tables for children and adults are not interchangeable due to differences in adjustment range and initial height, leading to increased space occupancy and costs, and existing solutions face issues with weight, stability, and processing costs.
Innovation Solution
A height adjustable table design featuring a lifting column with two sections of sleeves, allowing the tabletop support bracket to be installed at any position on the outer sleeve, driven by a mechanism that inverts the traditional arrangement to enable smooth adjustment and accommodate both children and adults without increasing weight or cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three or more sections of sleeve are used to increase adjustment range, then the adjustment range is improved, but the weight of the entire product increases
Solution Approach 1:
The patent inverts the traditional lifting column structure by placing the outer sleeve above the inner sleeve instead of the conventional arrangement. This inversion allows the telescopic sleeves to be arranged more efficiently, achieving the required adjustment range with only two sections rather than three or more, thereby reducing the overall weight of the product.
Solution Approach 2:
The lifting column is designed with a universal structure that can accommodate both children's tables (lower height) and adult tables (higher height) through the same two-section telescopic sleeve configuration. The outer sleeve can be positioned at different heights relative to the inner sleeve, providing adjustable range that serves multiple user groups without requiring separate specialized designs.
2Adaptability or versatility
If three or more sections of sleeve are used to increase adjustment range, then the adjustment range is improved, but the overall stability becomes difficult to guarantee
Solution Approach 1:
By inverting the sleeve arrangement with the outer sleeve positioned above the inner sleeve, the patent creates a more stable structural configuration. This inverted arrangement distributes mechanical loads more effectively and reduces the probability of problems compared to using three or more sections, while still achieving the required adjustment range.
Solution Approach 2:
The patent extracts the unnecessary third section of the telescopic sleeve, determining that only two sections are required to achieve the desired adjustment range. This reduction eliminates the instability issues associated with multiple sections while maintaining the necessary functionality.
3Adaptability or versatility
If three or more sections of sleeve are used to increase adjustment range, then the adjustment range is improved, but the number of screw rod sections increases causing interlacing waste
Solution Approach 1:
The inverted sleeve configuration allows the screw rods to be arranged more efficiently with only two sections instead of three or more. This eliminates the interlacing situation between adjacent sections that occurs in traditional multi-section designs, reducing material waste while maintaining the full adjustment range capability.
4Adaptability or versatility
If a long screw is used to achieve low and high height adjustment, then the height adjustment range is improved, but the processing costs increase and straightness deteriorates
Solution Approach 1:
The patent segments the lifting mechanism into two separate telescopic sleeve sections rather than using a single long screw. This segmentation allows each section to be manufactured independently at reasonable lengths, avoiding the high processing costs and straightness issues associated with manufacturing very long screws, while still achieving the required height adjustment range.

AI summary
The present invention discloses a height adjustable table, comprising a lifting column, a tabletop support bracket and a driving mechanism, wherein the lifting column is composed of a telescopic sleeve, and the telescopic sleeve comprises an outer sleeve and at least one inner sleeve. The tabletop support bracket is movably connected to the outer sleeve, and a connection position/area for the tabletop support bracket is formed on the side wall of the outer sleeve, and the tabletop support bracket is relatively fixed with the outer sleeve after adjusting the height from the ground according to the required installation position. The driving mechanism is configured to drive the lifting column to lift and lower, and the tabletop support bracket moves with the outer sleeve and stays at a preset position when the lifting and lowering stops. Compared with the prior art, the tabletop support bracket can be installed after adjusting the height from the ground according to the required installation position, so that the initial height of the tabletop support bracket is variable, thereby adapting to different lifting groups, and can be used by children and adults. During lifting and lowering, the inner sleeve does not move, and the driving mechanism drives the outer sleeve to lift and lower, so that the tabletop support bracket can be installed at any position of the outer sleeve and can be lifted and lowered smoothly.
