Nested Collapsible Table Structure for Stable Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible tables are difficult to assemble and lack structural stability, making them inefficient for compact storage and handling.
Innovation Solution
A collapsible table design featuring a horizontal support surface that articulates between extended and collapsed positions, with primary and secondary legs that pivot independently to maintain stability and facilitate easy assembly and disassembly, incorporating locking mechanisms to prevent unintended movement and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the table is designed to collapse for compact storage, then storage space efficiency is improved, but structural stability deteriorates
Solution Approach 1:
The patent implements a nested leg structure where secondary legs are positioned inside primary legs when collapsed, and primary legs are positioned inside table top apertures when fully collapsed. This nesting arrangement achieves compact storage volume while maintaining structural stability through the hierarchical support configuration.
Solution Approach 2:
The patent employs dynamic leg configurations that can transition between extended and collapsed positions. The legs include articulation points and locking mechanisms that allow the structure to adapt between stable extended configurations for use and compact collapsed configurations for storage, resolving the contradiction between stability and storage efficiency.
2Ease of operation
If the table legs are designed to pivot for collapse, then ease of assembly is improved, but structural stability worsens
Solution Approach 1:
The patent divides the leg structure into segmented components including primary legs, secondary legs, and articulation points. This segmentation allows independent pivoting of each leg segment for easy assembly while maintaining overall structural stability through the coordinated arrangement of segmented parts in extended positions.
Solution Approach 2:
The patent incorporates dynamic pivoting joints that enable easy assembly through simple rotational movements. The articulation points allow legs to pivot between stored and extended configurations, and when extended, the legs form stable geometric structures that maintain structural integrity during use.
3Stability of the object's composition
If locking mechanisms are added to prevent unintended movement, then structural stability is improved, but device complexity worsens
Solution Approach 1:
The patent implements self-locking mechanisms that automatically engage when legs are extended to their support positions. The locking features utilize the natural geometry and force distribution of the extended leg configuration to automatically secure the structure, eliminating the need for separate manual locking devices and keeping the mechanism simple while ensuring stability.
Solution Approach 2:
The patent integrates locking functions into the existing leg articulation points and connection joints rather than adding separate locking mechanisms. The connection structures combine pivoting capability with automatic locking features, merging multiple functions into unified components that maintain structural stability without increasing overall device complexity.

AI summary
Disclosed is a collapsible furniture article. The collapsible furniture article comprises a horizontal support surface that articulates about a main support between an extended position and a collapsed position with respect thereto. A first primary leg is connected to the main support pivotally between an extended position and a collapsed position with respect thereto. A first secondary leg is pivotally connected to the first primary leg pivotally between an extended position and a collapsed position with respect thereto. The legs in the extended position are disposed to support the horizontal support surface in a horizontal position. In collapsed position, the primary legs are positioned between the collapsed support horizontal surface and the collapsed secondary legs.
