Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding tables and benches are not conveniently integrated, requiring separate unfolding and folding operations, making them less practical for combined use and storage.
Innovation Solution
A folding integrated table and bench design featuring pivotally connected front and rear legs with sliding grooves and connecting shafts allows for synchronous folding and unfolding, enabling the bench and table boards to be turned vertically for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the folding table and folding bench are designed as independent products with firm structures, then structural stability is improved, but ease of operation deteriorates because they cannot be folded and unfolded synchronously
Solution Approach 1:
The patent combines the folding table and folding bench into a single integrated structure where the table board and bench board share common support legs. The legs are designed with unified folding mechanisms that allow both the table and bench to be folded and unfolded simultaneously through a single operation, resolving the contradiction between structural stability and ease of operation.
Solution Approach 2:
The patent introduces dynamic folding mechanisms with rotating joints and sliding grooves that enable the structure to transition between unfolded (stable for use) and folded (compact for storage) states. The legs can rotate relative to the support rod, and connecting shafts can slide within arc-shaped grooves, providing dynamic adaptability while maintaining stability when deployed.
2Device complexity
If the folding table and folding bench are designed to be folded separately, then structural simplicity is improved, but loss of time increases due to separate unfolding and folding operations
Solution Approach 1:
The patent merges the folding operations of the table and bench by integrating their support structures. Both the table board and bench board are supported by the same legs, which are connected to the support rod through rotating joints. This integration allows a single folding action to collapse both the table and bench simultaneously, reducing the time required for folding and unfolding while maintaining reasonable structural simplicity.
3Ease of operation
If the folding integrated table and bench use rotating joints and sliding grooves for synchronous folding, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent employs rotating joints at the connections between legs and support rod, and sliding grooves with connecting shafts that move along arc-shaped paths. These dynamic elements enable synchronous folding of both table and bench through intuitive rotational and sliding motions. While these mechanisms increase device complexity compared to simple hinged designs, they provide smooth, coordinated movement that significantly improves ease of operation.
Solution Approach 2:
The patent uses arc-shaped sliding grooves instead of straight grooves, allowing the connecting shafts to follow curved paths during folding. This curvature enables the legs to rotate inward in a coordinated manner, achieving compact folding while maintaining ease of operation. The arc-shaped design simplifies the folding motion compared to complex mechanical linkages.
4Adaptability or versatility
If the folding table and folding bench are used in combination as independent products, then adaptability is improved, but ease of operation deteriorates due to lack of coordination during folding
Solution Approach 1:
The patent merges the table and bench into a coordinated system where both seating and dining functions are provided by structures that fold together. The integrated design maintains adaptability by allowing the table board and bench board to be used separately or together, while the shared folding mechanism ensures synchronized collapse for compact storage, resolving the coordination issue.

AI summary
The present disclosure discloses a folding integrated table and bench comprising a front table board, a front bench board, a bracket, and two front legs. The front table board is pivotally connected to the bracket and is configured to be rotated relative to the bracket. Each of the two front legs comprises a first upper cross rod, a first vertical rod, a first lower cross rod, and a first standing rod connected in sequence. A top end of the first standing rod comprises a first connecting shaft, and the first vertical rod is rotatably connected to the bracket so that each of the two front legs is configured to be rotated to be folded and unfolded. A bottom surface of the front bench board is symmetrically disposed with two first sliding grooves.
