Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Height-adjustable tables with hydraulic or motorized mechanisms are bulky, heavy, and inflexible, making them unsuitable for frequent position changes and space-efficient storage.
Innovation Solution
A table design featuring a height-adjustable tabletop supported by straps that connect to side walls, allowing manual, stepless height adjustment and easy folding for compact storage, using a system of bands and a winding shaft with a hand crank for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulic or motorized mechanisms are used for height adjustment, then height adjustment comfort is improved, but device weight and bulk increase
Solution Approach 1:
The patent replaces complex hydraulic or motorized mechanisms with a simple manual crank mechanism. The crank converts rotational motion into linear motion of the support leg, enabling height adjustment through manual operation. This substitution eliminates heavy hydraulic cylinders or motors while maintaining adjustability functionality.
Solution Approach 2:
The invention extracts and removes the heavy hydraulic or motorized components from the support structure, retaining only the essential height adjustment functionality through a simplified manual mechanism. This extraction reduces overall device weight and bulk while preserving the core function of height adjustment.
2Measurement precision
If hydraulic or motorized mechanisms are used for height adjustment, then height adjustment precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex hydraulic control systems or motorized actuators with a simple manual crank mechanism. The crank provides direct mechanical control over the support leg position, achieving sufficient height adjustment precision without the complexity of fluid pressure control or electrical motor control systems.
Solution Approach 2:
The height adjustment mechanism is segmented into discrete rotational positions of the crank, which correspond to specific height positions of the table. This segmentation allows for controlled, precise height adjustments through discrete crank rotations rather than continuous complex control.
3Stability of the object's composition
If traditional support structures are used, then table top stability is improved, but storage space efficiency deteriorates
Solution Approach 1:
The support structures are designed to be dynamically adjustable between extended and retracted positions. When the table is not in use, the support legs can be folded or retracted to minimize the storage footprint, while during use they extend to provide stable support for the table top.
Solution Approach 2:
The support structures are designed to nest or fold into a compact configuration when not in use. The legs can be folded against each other or nested within the table frame, allowing the entire table to occupy minimal storage space while maintaining full functionality during use.
4Ease of manufacture
If fixed height tables are used, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The table incorporates dynamically adjustable support structures that allow the table height to be changed according to different user needs. This dynamic capability enables the same table to accommodate both sitting and standing work positions, as well as different user heights, while maintaining relatively simple manufacturing through the use of standardized adjustable components.

AI summary
In a table having a height-adjustable table top and supporting structures, the table top is secured on the supporting structures so that the supporting structures support the table top. The supporting structures are placeable on a floor. The table includes at least one band which connects the supporting structures and the table top to each other, so that the table top is supported by the supporting structures in that it hangs at the supporting structures with the aid of the band. The table permits a simple, convenient, quick and precise adjustment of the height of the table top according to the needs of the respective user of the table.
