Telescopic Folding Table Legs for Easy Single-Person Stowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding tables often require substantial strength to fold and unfold, frequently necessitating the assistance of more than one person due to the design of their foldable legs.
Innovation Solution
A folding table design featuring a plank rotationally connected to a vertical support member, with legs that include telescopic and pivoting mechanisms allowing for easy folding and stowing, reducing the need for excessive strength and enabling single-person operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional foldable legs are used, then the table can be folded, but substantial strength is required to fold and unfold
Solution Approach 1:
The leg is divided into two telescopic sections (first leg section and second leg section) that can slide relative to each other. This segmentation allows the leg to collapse into a compact configuration during folding, reducing the force and space required compared to a solid leg structure.
Solution Approach 2:
The leg incorporates dynamic telescopic joints with sliding surfaces that allow smooth relative motion between leg sections. This dynamic mechanism enables easy extension and retraction of the leg during folding operations, significantly reducing the strength required compared to rigid leg designs.
2Ease of operation
If traditional foldable legs are used, then the table can be folded, but more than one person is needed
Solution Approach 1:
The folding mechanism is designed to be self-operating through gravity-assisted telescopic collapse. When the plank is lifted to a vertical position, the legs automatically telescope inward and fold without requiring manual manipulation of multiple components, enabling single-person operation.
Solution Approach 2:
Multiple folding functions (plank rotation, leg telescoping, leg pivoting) are merged into a coordinated single-motion system. Lifting the plank vertically simultaneously triggers all folding actions, simplifying the operation to a single intuitive motion that one person can easily perform.
3Volume of moving object
If the plank rotates to vertical position, then the table is compact for storage, but the legs must be precisely positioned
Solution Approach 1:
The first leg section nests inside the second leg section through telescopic joints when the table is folded. This nested configuration achieves compact storage volume while the self-aligning sliding surfaces maintain adequate positioning precision without requiring extremely tight manufacturing tolerances.
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
The design allows for effortless folding and unfolding of the table, reducing the physical effort required and enabling solo operation, enhancing user convenience and accessibility.
Implementation Method 1
The second leg upper section is biased into a straight collinear position relative to the second leg lower section when the second leg is in a second leg deployed position

AI summary
A folding table has a plank, a substantially vertical support member, and a first leg having a first leg first section and a first leg second section. The first leg first section slides relative to the first leg second section when the table is folded between a deployed position and a stowed position. The first leg has an adjustable length. The first leg has a first leg upper joint allowing the first leg to fold between a first leg deployed position and a vertical stowed position. A second leg has a second leg first section and a second leg second section. The second leg first section is jointed to the second leg second section. The second leg has a second leg upper joint connected to the plank or the plank frame.
