Height adjustable table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer stands and desks often lack ergonomic adjustability, limiting user comfort during long periods of use, as they typically allow only a few pre-set positions or are difficult to adjust.
Innovation Solution
A height-adjustable table design featuring a worksurface, base, and linkage system that allows the worksurface to move between raised and lowered positions while remaining parallel to a fixed surface, incorporating telescoping risers and counterbalance mechanisms for easy height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stands or desks are used, then structural simplicity is maintained, but ergonomic adjustability is limited
Solution Approach 1:
The patent implements telescoping risers where movable members are nested within stationary members, allowing the worksurface to be adjusted to multiple heights while maintaining a compact structure when collapsed. This nesting approach enables height variability without proportionally increasing the overall structural complexity.
Solution Approach 2:
The patent transitions from a static fixed worksurface to a dynamic adjustable worksurface by incorporating telescoping risers with movable members that can extend and retract. This allows the table height to be changed from a fixed state to a variable state, improving adaptability while using controlled mechanical mechanisms.
2Ease of operation
If pre-set position stands are used, then adjustment mechanism is simplified, but user comfort is reduced
Solution Approach 1:
The patent implements a dynamically adjustable worksurface using telescoping risers that can be extended or retracted to achieve multiple height positions. The linkage mechanism enables smooth transitions between positions, providing both ease of operation and continuous position variability rather than fixed pre-set positions.
Solution Approach 2:
The patent divides the worksurface into a fixed surface and a height-adjustable surface, with the adjustable portion supported by segmented telescoping risers. This segmentation allows independent adjustment of the worksurface height while maintaining structural integrity, enabling easy operation with multiple position options.
3Stability of the object's composition
If heavy worksurface is used, then structural stability is improved, but adjustment force requirement increases
Solution Approach 1:
The patent incorporates a counterbalance mechanism that applies an opposing force to offset the weight of the height-adjustable surface during movement. This counterbalance system reduces the net force required by the user to extend or retract the telescoping risers, enabling easy adjustment of heavy worksurfaces while maintaining stability.
Solution Approach 2:
The patent replaces direct manual lifting of the heavy worksurface with a mechanical advantage system using linkages and counterbalance mechanisms. This mechanical substitution transforms the adjustment action from direct weight opposition to a controlled mechanical process, reducing the effort force needed while maintaining worksurface stability.

AI summary
A height adjustable table can include a plurality of legs, a lower portion, a worksurface, a height adjustable surface, and a linkage. The worksurface can be supported by the plurality of legs and can include a fixed surface and a height adjustable surface. The fixed surface can be secured to at least one of the lower portion and the plurality of legs, and the fixed surface can define a recessed portion. The height adjustable surface can be movable between a raised position and a lowered position so that the height-adjustable surface retracts into the recessed portion when in the lowered position so that the height adjustable surface is coplanar with the fixed surface. The linkage can be configured to move the height adjustable surface between the lowered position and the raised position so that the height adjustable surface remains parallel to the fixed surface.
