Collapsible adjustable height table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collapsible, adjustable height tables are limited in their compactness due to the dimensions of their legs, which restrict the minimum width of the collapsed apparatus and the achievable height when extended.
Innovation Solution
The use of telescoping legs with a central pivot mechanism that allows for folding and expansion without limiting the leg length, combined with a gas compression spring for height adjustment, enables a reduced folded size without compromising the maximum height of the table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the legs are made longer to achieve greater table height, then the maximum height of the table is improved, but the minimum width of the collapsed apparatus increases
Solution Approach 1:
The patent implements telescoping legs where one leg section is nested within another, allowing the legs to collapse into a compact configuration that does not extend beyond the table width while maintaining the capability to extend to greater heights when deployed
Solution Approach 2:
The patent introduces a vertical telescoping dimension to the leg structure, allowing the legs to achieve greater effective length in the vertical direction without increasing the horizontal footprint when collapsed, thereby resolving the contradiction between height and collapsed width
2Area of stationary object
If the ironing surface is reduced in size to make the apparatus more compact, then the collapsed dimensions are improved, but the legs extend beyond the width of the surface when collapsed
Solution Approach 1:
The telescoping leg mechanism allows the legs to be nested within the table structure when collapsed, ensuring they do not extend beyond the table surface width, thereby maintaining a compact and aesthetically pleasing collapsed configuration regardless of surface size
3Area of stationary object
If conventional folding mechanisms are used to reduce collapsed size, then the compactness is improved, but the maximum achievable height is limited
Solution Approach 1:
The legs are divided into multiple telescoping sections that can be independently extended and locked at various heights, allowing the table to achieve greater maximum heights while maintaining a compact collapsed size, as each section can be nested within the others when not in use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for a compact folded configuration without the legs extending beyond the table width, maintaining the ability to achieve desired heights, thus offering a more versatile and space-efficient solution for collapsible tables and similar apparatuses.
Implementation Method 1
A collapsible, adjustable height table is disclosed that provides a reduced folded size compared to conventional collapsible, adjustable tables and other apparatuses. This multi-purpose apparatus may include a gas compression spring, or similar mechanism, to facilitate extending the table to desired heights.

AI summary
A range limiter to secure or position a adjustable height, foldable table at a particular height. A two-way spring-loaded plunger is positioned at the end of a leg for engagement with a stop component. The stop component is affixed to the bottom of the table top. When the leg is in a storage position, the plunger is pushed outward preventing the table leg from opening too far. The two springs have different forces or strengths associated with them. An extension section of the leg pushes against a heavy spring when the table is collapsed, thereby pushing the plunger outward. A light spring keeps the plunger withdrawn when the leg is extended.
