Collapsible adjustable height table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collapsible, adjustable height tables are limited by the length of their legs, which restricts the minimum width of the collapsed apparatus and the maximum height it can achieve.
Innovation Solution
The use of novel telescoping legs with a central pivot that allows the legs to rotate and fold, enabling the table to be adjusted to various heights without the legs extending beyond the width of the table top when collapsed.
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 form. The telescoping mechanism enables the legs to reduce to a minimum width when collapsed, independent of their extended length, thereby resolving the contradiction between achieving greater table height and maintaining compact collapsed dimensions.
Solution Approach 2:
The patent introduces a central pivot mechanism that allows the legs to rotate and fold in a different dimensional plane. Instead of the legs extending linearly outward when collapsed, they rotate about the central pivot to fold against the table top, effectively utilizing a rotational dimension to achieve compact storage while maintaining full leg length for height adjustment.
2Area of stationary object
If the legs are shortened to reduce collapsed width, then the minimum width of the collapsed apparatus is improved, but the maximum height of the table is reduced
Solution Approach 1:
The telescoping leg design allows multiple leg sections to nest within each other during collapse, enabling the legs to achieve a compact width without sacrificing their fully extended length. This nesting mechanism decouples the relationship between collapsed width and extended height, allowing optimization of both parameters independently.
3Area of stationary object
If the ironing surface is reduced in size to achieve compactness, then the collapsed width is improved, but the legs extend beyond the width of the ironing surface when collapsed
Solution Approach 1:
The central pivot mechanism enables the legs to rotate and fold in a dimensional plane that allows them to retract within the boundaries of the table top when collapsed. This rotational folding action, rather than linear collapse, ensures that the legs remain positioned within the table top width even when the table is in its compact state, eliminating the protrusion issue.

AI summary
A telescoping leg assembly with a pivot apparatus having a first and second telescoping leg, each with an extension section and a sleeve component, the sleeve component divided longitudinally into a first space and second space. The leg extension sections are dimensioned to retract into and telescope from the first space in the first leg sleeve component. The telescoping legs are pivotally attached to one another by a pivot apparatus on the sleeve portions, wherein the pivot apparatus extends into the second spaces of the sleeve components.
