Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tables are rigid, heavy, and difficult to move or store due to their inflexible structure, despite having wheels for improved mobility.
Innovation Solution
A foldable and height-adjustable table design featuring a main frame with sliding vertical posts, locking units, and a wheel assembly that allows for adjustable height and easy folding, enabling convenient use, storage, and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional table uses a rigid structure to support objects, then the table has high stability and strength, but the table becomes heavy and difficult to move and store
Solution Approach 1:
The table frame is divided into multiple telescopic leg assemblies, each independently adjustable. The legs are segmented into inner and outer tubes that can slide relative to each other, allowing the table to be disassembled into compact sections for easy storage and transport while maintaining structural integrity when assembled.
Solution Approach 2:
The table employs dynamic telescopic leg mechanisms with locking systems that allow the legs to be extended or retracted. The locking units enable the table to transition between a stable expanded state for use and a compact folded state for storage, providing both stability during operation and ease of movement when needed.
2Device complexity
If a conventional table has a fixed rigid structure, then the table is simple in design, but the table lacks height adjustability and folding capability
Solution Approach 1:
The table employs telescopic leg assemblies with locking mechanisms that enable height adjustment while maintaining a relatively simple overall structure. The locking units secure the legs at desired heights, providing adaptability without excessive complexity. The same telescopic mechanism also enables folding capability, allowing the table to transition between extended and collapsed states.
Solution Approach 2:
The telescopic leg assembly serves multiple functions: it provides height adjustment, enables folding for compact storage, and maintains structural support. This multi-functional design achieves adaptability and versatility without requiring separate mechanisms for each function, thereby controlling overall structural complexity.

AI summary
A foldable and height-adjustable table may include a main frame, a foldable frame, and a wheel assembly. The main frame has two side frames which are separated with a distance and parallel with each other. Each of the side frames has a vertical front sleeve and a vertical rear sleeve, and each of top bars horizontally located at a top end of the side frame. A table top has a pivotal side edge pivotally coupled with one of the top bars and an opposed detachable side edge detachably coupled with another top bar. The table top is configured to be coupled on tops of the top bars for use or pivotally turned over to couple at an outer edge of the side frame for store, and the main frame is configured to be folded between the folded position and unfolded position.
