Retractable and foldable table leg structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable computer tables have fixed height legs, which do not allow for user-adjustable height, limiting their adaptability to different needs.
Innovation Solution
A retractable and foldable table leg structure featuring a frame with a receiving cavity and supporting legs composed of slidably and rotatably connected rods, allowing for adjustable height through sliding and locking mechanisms, enabling the legs to be fully or partially retracted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the legs are made foldable for compact storage, then the table occupies less space for transportation and storage, but the height of the table cannot be adjusted
Solution Approach 1:
The leg structure transitions from a static fixed-height design to a dynamic adjustable-height design. The telescopic mechanism allows the leg length to be changed by sliding the inner tube relative to the outer tube, enabling height adjustment while maintaining the foldable capability for compact storage.
Solution Approach 2:
The leg employs a telescopic structure where the inner tube is nested within the outer tube. When folded, the inner tube retracts into the outer tube, achieving compact storage. When extended, the inner tube slides out to provide adjustable height, resolving the contradiction between compactness and height adjustability.
2Adaptability or versatility
If the legs are made adjustable in length, then the table height can be adjusted to meet user demands, but the structure becomes more complex
Solution Approach 1:
The leg is divided into multiple segments: the outer tube, inner tube, sliding rail, and limiting pillar. This segmentation allows each component to perform a specific function while working together to achieve height adjustment. The segmented design enables adjustability without requiring an overly complex overall structure.
Solution Approach 2:
The leg structure uses a dynamic telescopic mechanism with sliding rails and limiting pillars that allow smooth height adjustment. The limiting pillars guide the sliding motion and prevent excessive extension, providing controlled adjustability while maintaining structural simplicity through well-defined mechanical constraints.

AI summary
The present disclosure provides a retractable and foldable table leg structure, including a frame and a supporting leg. The frame defines a receiving cavity. The supporting leg includes a first supporting rod, a second supporting rod, a third supporting rod and a fourth supporting rod. The third supporting rod is slidably connected with the first supporting rod. The fourth supporting rod is slidably connected with the second supporting rod. The first supporting rod and the second supporting rod are rotatably connected with the frame, respectively. The supporting leg is configured to rotate to be received within the receiving cavity, and is adjustable in height by sliding the third supporting rod and the fourth supporting rod.
