Expandable folding table with removable insert panel assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional expandable folding tables cannot be both folded and extended without structural interference, limiting their adaptability to varying space needs.
Innovation Solution
A retractable panel assembly featuring a movable panel connected to a sliding rail device within a pivot frame, allowing the panel to extend the table length when needed and fold under the fixed frame for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If an extra panel is added to extend the table length, then the table space is increased, but the folding function is interfered with due to structural interference
Solution Approach 1:
The table top is divided into multiple independent panels (first panel, second panel, and movable panel) that can move relative to each other. The movable panel is separated from the fixed panels and connected via sliding rail device, allowing independent movement for extension without interfering with the folding mechanism of the fixed panels.
Solution Approach 2:
The movable panel is designed to be stored within the space between the fixed panels when not in use. During extension, the movable panel slides out from its stored position; during folding, it retracts back into the nested space, allowing the extended table to collapse to its original compact size.
2Volume of moving object
If the table is designed to be folded for compact storage, then the storage space is reduced, but the table top cannot be expanded
Solution Approach 1:
The table design incorporates a dynamic movable panel that can transition between extended and retracted positions. When the table is in use, the movable panel extends to increase table top area; when storage is needed, it retracts to allow compact folding, making the table adaptable to different spatial requirements.
Solution Approach 2:
The movable panel serves dual functions: it extends the table top area during use and provides compact storage during folding. This multi-functional design allows a single table structure to satisfy both expansion and compact storage requirements without needing separate designs for different scenarios.
3Adaptability or versatility
If a movable panel is added to enable extension, then the table length is adjustable, but the device complexity increases
Solution Approach 1:
The sliding rail device acts as an intermediary mechanism between the movable panel and the fixed panels. It provides a simple guide and constraint system that enables smooth extension and retraction of the movable panel without requiring complex actuators, motors, or control systems, thus adding adjustability with minimal complexity increase.

AI summary
The present subject matter discloses a removable panel assembly for an expandable folding table. The removable panel assembly includes a movable panel and a frame that is retractable. The expandable frame also includes a fixed frame connected with a pivot device and a movable frame. The movable panel is foldable and can be horizontally arranged between two panels of the folding tables when it is in use. Furthermore, the movable panel can be stored under the fixed frame when it is collapsed. With the removable panel assembly, the table can be both foldable and extendable without structural interference. In addition, while being easy to operate, the removable panel assembly further enhances the functions and appearance of the table.
