Integrated Folding Table Frame for Stable Compact Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding tables are inconvenient to operate due to separate unfolding of the table plane and support frame, lack stability, and are difficult to pack and transport due to inhomogeneous forces from the support legs.
Innovation Solution
A conjoined folding table design with a table plane connected to support frames via battens, slide support rods, slant support rods, pull rods, and pivotal members, forming stable triangle structures for integral support and folding, allowing for compact storage and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the table plane and support frame are separated into two parts, then the table can be assembled in a conventional manner, but the table becomes inconvenient to pack, transport, and carry
Solution Approach 1:
The patent combines the table plane and support frame into a single integrated folding structure. The table plane is directly connected to the support frame through folding joints, allowing both components to move together as one unit. This eliminates the need to separate the table plane from the support frame during packing, making the entire table foldable into a compact form for easy transport and storage.
2Ease of manufacture
If the table plane and support frame are unfolded separately, then the assembly process is conventional, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The table plane and support frame are connected through folding joints that allow them to unfold simultaneously. When the support frame is unfolded, the table plane automatically follows and unfolds at the same time, eliminating the sequential unfolding process of conventional tables. This synchronized unfolding mechanism significantly reduces the time and steps required to set up the table.
3Device complexity
If conventional support legs are used, then the structure is simple, but the table shakes due to inhomogeneous forces when the table plane is pressed
Solution Approach 1:
The support legs are designed with folding joints and connecting rods that allow dynamic adjustment and coordination of forces. When the table plane is pressed, the connecting rods transmit and distribute the applied force uniformly across all support legs through a system of linked joints. This dynamic force distribution mechanism prevents the inhomogeneous forces that cause shaking in conventional static support leg designs.

AI summary
A conjoined folding table includes a table plane and plane support frames, wherein under the table plane are disposed two groups of identical support frames. Each group of plane support frames includes two support legs, two slide support rods, a slide block, two slant support rods, a pull rod, a stay bar, two plane support traverse tubes, a pivotal member, and a U-shaped hinge. The slide support rod is connected to the support leg via a slide block, and the upper end of the slide support rod is movably hinged with the plane support traverse tube. The lower ends of the two slide support rods are rotatably connected via a rotary member, or one end of slide support rod is connected to the support leg via a slide block, and the other end is connected to the plane support traverse via a slide block and is provided with a cross support rod.
