Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sit-stand office desks are underutilized due to perceived ugliness and high costs, primarily because they are often bulky and expensive, lacking aesthetically pleasing designs while meeting stability requirements, and have complex assembly processes.
Innovation Solution
A sit-stand table design featuring telescopic legs with a hollow profile structure, driven by elastic springs and traction means, allowing for height adjustment with a slim and stable four-legged frame, reducing component and assembly costs while maintaining mechanical stability and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the table frame is designed with four legs for aesthetic appeal, then the visual appearance is improved, but the mechanical stability deteriorates
Solution Approach 1:
The patent introduces diagonal bracing elements that add structural rigidity through geometric triangulation, transforming the frame from a simple rectangular configuration to a more complex three-dimensional truss structure. This dimensional enhancement provides the necessary mechanical stability while preserving the four-legged aesthetic form.
Solution Approach 2:
The frame construction combines different materials and structural components - including metal tubes, wooden elements, and reinforcement brackets - to create a composite structure that achieves both visual appeal and mechanical stability. The heterogeneous material composition allows optimization of both aesthetic and structural properties.
2Stability of the object's composition
If expensive components and complex assembly processes are used to achieve stability, then the mechanical stability is improved, but the manufacturing cost increases
Solution Approach 1:
The table frame is divided into modular segments - individual legs, cross-bracing elements, and connection joints - that can be manufactured separately using standardized processes and then assembled through simple connection mechanisms. This segmentation reduces manufacturing complexity and assembly costs while maintaining overall structural stability.
Solution Approach 2:
The patent employs cost-effective connection solutions such as simple metal brackets, screws, and adhesive joints rather than expensive specialized fasteners. These straightforward connection elements achieve sufficient structural integrity without requiring costly components or complex assembly procedures.

AI summary
The invention relates to a sit-stand table having four telescoping legs, the upper leg sections (15) of which table are rigidly connected to a central cross member (2), wherein movement of an elastic spring (57) is movement-coupled by traction means (21, 22) to relative movement between the upper leg sections (15) and lower leg sections (16). The cross member (2) is rigidly connected to each of the individual upper leg sections (15) by a lateral support (33) and by a diagonal strut (34). The traction means (21, 22) extend through the diagonal strut (34), which is designed as a hollow profile.
