Dual-purpose folding table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding tables are space-inefficient when not in use, unstable when placed against a wall, and inconvenient to clean, as they often slip and occupy valuable floor space.
Innovation Solution
A dual-purpose folding table design featuring symmetrically disposed supporting frames with X-shaped rotatable connections, a hook structure for wall mounting, and sliding sleeves with a locking mechanism to securely hang and open the table board, allowing it to be used as a conventional table or mounted on the wall, preventing slipping and optimizing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the folding table is placed against the wall to save space, then the space occupation is reduced, but the table becomes unstable and easily slips
Solution Approach 1:
The patent introduces a hook structure that enables the folding table to be mounted on the wall in a vertical dimension, transforming it from a ground-based horizontal placement to a wall-mounted vertical suspension. This dimensional change allows the table to be stored against the wall without occupying floor space while maintaining stability through the hook's anchoring mechanism.
Solution Approach 2:
The hook structure serves as an intermediary element between the folding table and the wall. It provides a stable connection point that prevents the table from slipping when placed against the wall, resolving the instability issue while enabling space-saving vertical storage.
2Adaptability or versatility
If the folding table is opened for use, then the table function is available, but the space becomes more crowded and inconvenient to use
Solution Approach 1:
The patent employs a dynamic design where the table board can be rotated between a folded position (against the wall) and an opened position (for use). The supporting frames with X-shaped rotatable connections enable smooth transition between these states, allowing the table to adapt to different usage scenarios while minimizing space occupation when not in use.
Solution Approach 2:
The table is divided into separable components: the table board and the supporting frames. This segmentation allows the table board to be independently rotated and opened for use, while the supporting frames remain anchored to the wall, enabling functional versatility without requiring the entire structure to occupy significant space.
3Stability of the object's composition
If the folding table is placed on the ground, then the table is stable, but it occupies valuable floor space
Solution Approach 1:
The patent transitions the table from ground-based horizontal placement to wall-mounted vertical suspension. By utilizing the vertical dimension and mounting the table on the wall through the hook structure, the design eliminates floor space occupation while maintaining stability through the wall's structural support.
4Area of stationary object
If the folding table is folded and placed against the wall, then space is saved, but the table slips and is inconvenient for cleaning the floor
Solution Approach 1:
The hook structure acts as an intermediary that securely anchors the folding table to the wall, preventing it from slipping during storage. This stable wall-mounted position elevates the table above the floor surface, creating clear access for floor cleaning operations and eliminating the inconvenience of cleaning around a slippage-prone ground-based table.

AI summary
A dual-purpose folding table comprises a table board and two supporting frames. An upper portion of an outer leg pipe is pivotally connected to a rear portion of a side of the table board. A front portion of a bottom surface of the table board comprises a blocking portion corresponding to an inner leg pipe. The two supporting frames comprise a hook structure. The outer leg pipe is sleeved with a sliding sleeve located above a rotation point of the inner leg pipe and the outer leg pipe. A supporting rod is connected between a middle portion of the side of the table board and the sliding sleeve. Two ends of the supporting rod are pivotally connected to the sliding sleeve and the table board. The sliding sleeve is disposed with a locking member for locking the sliding sleeve to the outer leg pipe.
