Foldable Lifting Desk Linkage for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting desks occupy large spaces and are inconvenient for storage, movement, and transportation due to their non-foldable design, which includes a desk top and support legs.
Innovation Solution
A foldable lifting desk design featuring a support frame with an inner and outer pipe mechanism, connecting bars, a slide bar, and a control module that allows the desk top and base to be folded, reducing the overall size by forming linking mechanisms that enable the desk top and base to be inclined and folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lifting desk uses a traditional support frame with desk top and support legs, then the desk provides stable support and structural integrity, but the desk occupies large space and is inconvenient to store, move and transport
Solution Approach 1:
The patent implements a telescopic support frame where the inner pipe is inserted into the outer pipe, allowing the support structure to nest within itself. The connecting bar and drawing bar mechanisms enable the inner pipe to extend and retract smoothly within the outer pipe, reducing the overall volume when collapsed while maintaining structural integrity when extended
Solution Approach 2:
The patent employs a dynamic support frame that can transition between extended and collapsed states through the telescopic mechanism. The pivotable connections and sliding components allow the structure to adapt its configuration, transforming from a rigid fixed-size frame to a dynamic adjustable structure that minimizes storage volume
2Stability of the object's composition
If the lifting desk has a fixed non-foldable design, then the desk provides stable support, but the desk is inconvenient to store, move and transport
Solution Approach 1:
The patent transforms the static fixed design into a dynamic foldable structure. The support frame with telescopic pipes and the desk top with pivotable connections can dynamically change between extended working configuration and collapsed storage configuration, providing both stability during use and ease of storage when not in use
Solution Approach 2:
The patent divides the desk into separable components including the desk top, support frame with telescopic pipes, and base, connected through pivotable joints. This segmentation allows each component to move independently, enabling the desk to be folded and collapsed for easy storage and transport while maintaining structural integrity
3Volume of moving object
If the lifting desk uses a foldable design with linking mechanisms, then the desk reduces overall size for easier storage and transport, but the structure becomes more complex
Solution Approach 1:
The telescopic support frame with inner pipe nested within outer pipe provides an efficient folding mechanism that achieves compact storage volume without requiring multiple separate components. The nested design inherently reduces complexity compared to alternative folding mechanisms while maintaining the ability to collapse the desk to a small size

AI summary
A lifting desk includes a desk top, a support frame and a base. The support frame has an inner pipe with a top end, a bottom end, and an outer pipe. The inner pipe is movably inserted into the outer pipe, the top end of the inner pipe pivotally joining the desk top, the bottom end of the outer pipe pivotally joining the base; a connecting bar and a drawing bar, one end of the connecting bar pivotally joining the center position of the inner pipe, the other end slidably connected to the bottom surface of the desk top, one end of the drawing bar pivotally joining the base, the other end of the drawing bar slidably connected to the outer pipe. The desk top, the inner pipe and the connecting bar form a link mechanism. The outer pipe, the base and the drawing bar form a second link mechanism.
