Locking mechanism for a folding table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banquet tables are bulky, difficult to store, and require significant space due to their large size, making them inconvenient and costly to move and transport, and often lack the strength to support heavy loads, with complex setup and teardown processes.
Innovation Solution
A folding table design featuring a blow-molded plastic tabletop and movable support structures that can be easily collapsed and unfolded, with a locking mechanism for secure positioning, allowing for compact storage and transportation, and constructed from lightweight yet durable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional banquet tables are made large to provide sufficient surface area, then the table can support more people and items, but the table becomes bulky and requires large storage area
Solution Approach 1:
The tabletop is divided into two separate sections that can be folded relative to each other. When folded, the sections are positioned adjacent to each other, reducing the overall footprint and storage area required while maintaining full surface area when unfolded for use.
2Area of moving object
If conventional banquet tables are made large to provide sufficient surface area, then the table can support more people and items, but the table becomes difficult to move and transport
Solution Approach 1:
The table is divided into foldable sections that can be collapsed to a compact size. This segmentation allows a single person to easily move and transport the table by folding it to a manageable size, while still providing full surface area when set up for use.
3Ease of operation
If the connection between tabletop sections is made weak to allow easy folding, then the table becomes easier to collapse for storage, but the connection allows the tabletop to sag or slump under load
Solution Approach 1:
A locking mechanism is incorporated that automatically engages when the table is unfolded, securing the tabletop sections in a rigid position before use. This preliminary locking action ensures the table can support loads without sagging, while still allowing easy folding when the lock is disengaged.
Solution Approach 2:
The connection between tabletop sections transitions from a static rigid joint to a dynamic system that can switch between locked (rigid) and unlocked (flexible) states. This allows the table to be easily folded for storage while maintaining structural strength when locked in the unfolded position.
4Reliability
If multiple steps are required to set up and take down the table, then the locking and support mechanisms can be more secure, but the setup and teardown processes become time consuming
Solution Approach 1:
The locking mechanism is designed to automatically engage when the table is unfolded, eliminating the need for manual locking steps. This preliminary automatic locking ensures secure positioning while significantly reducing the time required for setup and teardown operations.

AI summary
A foldable table may include a tabletop and legs that are movable between an extended position and a collapsed position. The tabletop may include a first section and a second section that are connected by a hinge assembly. A locking mechanism may be sized and configured to lock the hinge assembly in a fixed position. The locking mechanism may include a locking member, and the locking member may be a unitary, one-piece structure. The locking member may be rotatably connected to a connector of the hinge assembly. The locking member may be connected to a locking structure that is movable between a locked position and an unlocked position. The locking member may be sized and configured to bias the locking structure into the locked position.
