Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding tables made from lightweight materials face challenges in providing sufficient stability and durability while maintaining portability, as they often struggle to withstand the rigors of use without compromising on strength and sturdiness.
Innovation Solution
A folding table design featuring a table top with angled sockets and legs that rotate from a folded to an extended position, where the legs extend beyond the table's perimeter to increase mechanical stability, using a mechanism with resilient tabs and slots to lock the legs in place, allowing for enhanced stability and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight materials are used for the table, then portability is improved, but stability and strength deteriorate
Solution Approach 1:
The patent employs dynamic leg structures that can transition between folded and extended positions, allowing the table to adapt its stability characteristics based on operational needs. The legs include movable joints and extension mechanisms that enable the table to provide enhanced stability when fully extended while maintaining portability when folded for transport.
Solution Approach 2:
The patent introduces additional dimensional elements through leg extensions that protrude beyond the table perimeter in horizontal directions. This creates a wider support base footprint without increasing vertical height, thereby improving stability in the horizontal plane while maintaining the lightweight portable structure.
2Stability of the object's composition
If legs are extended beyond the table perimeter to increase stability, then mechanical stability is improved, but device complexity increases
Solution Approach 1:
The patent divides each leg into multiple segments including a main leg body, extension portions, and locking mechanisms. This segmentation allows the legs to achieve extended stable configurations while maintaining the ability to fold compactly, managing complexity through modular design that enables independent control of each leg segment.
Solution Approach 2:
The patent incorporates self-locking mechanisms within the leg structures that automatically engage to maintain extended positions during use. These self-service features reduce the need for continuous manual adjustment and simplify operation, allowing the complex extended configuration to be achieved and maintained without proportionally increasing operational complexity.

AI summary
A foldable table that provides a stable operational position in which the table legs may extend beyond the footprint of the table, and a folded, storage position in which the table legs may be tucked within the footprint of the table. An aspect provides table legs that may slide and pivot within sockets of a table top, to enable the legs to lock into the extended position and to also pivot flat against a horizontal undersurface of the table top.
