Folding Table Locking Mechanism for Compact Storage Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banquet tables are bulky, difficult to store, and require significant space due to their fixed size and length, making them inconvenient and costly to rent, transport, and store, especially for smaller facilities.
Innovation Solution
A table design with a foldable top and legs that can be easily moved between extended and collapsed positions, featuring a locking mechanism that automatically locks the top in the unfolded position when the legs are extended, allowing for compact storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the table top is made foldable to reduce storage space, then the storage area requirement decreases, but the table top may unintentionally fold or unfold and the structure becomes more complex
Solution Approach 1:
The table top is divided into two separate sections that can be folded relative to each other. This segmentation allows the table to be collapsed to a fraction of its original size for storage while maintaining structural integrity when extended for use.
Solution Approach 2:
A locking mechanism is pre-configured to automatically engage when the table top is in the extended position, preventing unintentional folding. The locking arms are positioned and dimensioned to automatically lock the table top sections together when the table is set up, eliminating the need for manual locking actions.
2Reliability
If conventional locking mechanisms are used to prevent unintentional folding, then the table top stability improves, but the mechanism becomes complex and heavy
Solution Approach 1:
The locking mechanism is designed to be self-actuating based on the table's configuration. When the table top is extended to its full length, the locking arms automatically engage with the locking surfaces to secure the table top sections together. When the table is collapsed, the locking arms disengage automatically, eliminating the need for separate locking actions or complex control systems.
Solution Approach 2:
The locking mechanism utilizes changes in the geometric parameters of the table structure during extension and collapse. As the table top sections move relative to each other, the distance and angle between locking surfaces change, causing the locking arms to naturally engage or disengage based on the table's extended or collapsed state.
3Ease of operation
If the table length is reduced to enable single-person transport, then the ease of operation improves, but the table functionality for large groups is compromised
Solution Approach 1:
The table is designed with dynamic characteristics that allow it to change its effective length and configuration. The table top can be folded to reduce the overall length for transport, and the legs can be collapsed to minimize the footprint. When set up, the table extends to its full functional length to accommodate large groups, providing adaptability between transport and use states.

AI summary
A table may include a table top and a leg assembly. The leg assembly may be moved between use and storage positions, and the movement of the leg assembly may move a cross member between a first position in which the cross member resists folding of the table top and a second position in which the cross member facilitates folding and unfolding of the table top. The table top may include first and second sections with portions that overlap and/or interlock when the table top is unfolded. When the table top is in the unfolded position, movement of the leg assembly towards the use position may move the cross member towards the overlapping and/or interlocking portions, which may move the overlapping and/or interlocking portions towards each other. When moved towards each other, the overlapping and/or interlocking portions may be securely connected.
