Interlocking Folding Table Frame for Compact Storage and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banquet tables are bulky, difficult to store, transport, and require significant space due to their large size, even when legs are folded, and often lack the strength to support heavy loads, making them inconvenient and costly to use and move.
Innovation Solution
A folding table design featuring a blow-molded plastic table top and a frame with nested, interlocking side rails that allow the table to be compactly folded while maintaining strength and rigidity, enabling easier storage, transportation, and use in smaller spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional banquet tables with large table tops and folding legs are used, then the table can be more conveniently stored, but the table top retains its size and shape requiring a large storage area
Solution Approach 1:
The table top is divided into two sections that can be folded relative to each other, allowing the table to be collapsed to a fraction of its original size while maintaining the full table top area when in use
Solution Approach 2:
The frame portions are designed to nest within each other when the table is folded, with one portion containing or receiving another portion, significantly reducing the storage footprint while preserving the full operational size
2Volume of moving object
If conventional fold-in-half tables with foldable table tops are constructed, then the table can be folded to reduce size, but the connection between sections is weak and cannot support significant weight
Solution Approach 1:
The frame is constructed from high-density polyethylene material providing both strength and flexibility, allowing the frame to support significant weight while maintaining the ability to fold and collapse effectively
Solution Approach 2:
The frame portions are designed with nesting capabilities where one portion contains or receives another portion, allowing the table to collapse to a compact size while maintaining structural integrity and weight support capacity
3Area of moving object
If conventional banquet tables with extended length are used, then the table provides sufficient surface area, but it is difficult for a single person to move or transport
Solution Approach 1:
The table is designed with segmented sections that can be folded relative to each other, allowing a single person to easily lift and maneuver the table while maintaining sufficient surface area when in use
Solution Approach 2:
The table incorporates movable and collapsible components including foldable sections and nesting frame portions, transforming the table from a static, difficult-to-move object to a dynamic structure that can be easily configured and transported by one person

AI summary
A foldable table may include a table top and legs movable between an extended position and a collapsed position. A first portion of a side rail may be connected to a first table top section and a second portion of the first side rail may be connected to a second table top section. An engaging portion of the first portion of the side rail may be at least partially disposed in a receiving portion of the second portion of the side rail when the table top is in the folded position and an engaging portion of the second portion of the side rail may be at least partially disposed in a receiving portion of the first portion of the side rail when the table top is in the folded position.
