Solution Overview
Problem
Existing power-driven table stands face issues with complex assembly, heavy weight, large size, and inconsistent height adjustments due to manual operation of pneumatic or power-driven cylinders, leading to poor user experience and inefficient use of space.
Innovation Solution
A collapsible power-driven table stand design featuring a supporting body with pivotally attached extendable stands driven by motors and screw mechanisms, allowing for compact storage and easy assembly, with concealed components for a sleek appearance and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pneumatic cylinders are used for table height adjustment, then assembly is simplified, but height adjustment precision deteriorates due to high-speed lifting and manual lowering requirements
Solution Approach 1:
The patent replaces the pneumatic cylinder mechanical system with an electric motor-driven screw mechanism. The motor rotates a screw that translates rotational motion into linear motion of the table stand, providing precise height control while maintaining simple assembly. The screw mechanism inherently provides mechanical advantage and positioning precision without requiring manual intervention during operation.
2Manufacturing precision
If power-driven cylinders are used for height adjustment, then height adjustment precision is improved, but device complexity, weight, and size increase
Solution Approach 1:
The patent segments the power-driven system into separate functional components: a motor unit, a screw mechanism, and a table stand. The motor is mounted on the table stand which is separate from the tabletop, allowing independent adjustment without complicating the overall structure. This modular segmentation reduces device complexity while maintaining precise height adjustment capability.
3Strength
If traditional table stands are used, then structural strength is maintained, but overall size and storage space requirements increase
Solution Approach 1:
The patent employs a dynamic table stand structure that can extend and retract along the longitudinal axis of the tabletop. The stand includes extendable rod members that can be adjusted to different lengths, allowing the structure to adapt between a compact retracted state for small storage volume and an extended state for full structural strength and functionality. This dynamic adjustment enables the structure to maintain strength when needed while minimizing size during storage.

AI summary
A collapsible power-driven table stand includes a supporting body of an elongated shape, a first stand having a first driving member and a plurality of first extendable rods driven by the first driving member to move axially relative to each other and a second stand having a second driving member and a plurality of second extendable rods driven by the second driving member to move axially relative to each other. The first diving member is pivotally attached to one end of the supporting body and the second diving member is also pivotally attached to another end of the supporting body in order to allow both the first and second stands to extend/collapse relative to the supporting body. Accordingly, the assembly of the collapsible power-driven table is simplified and the overall size thereof is reduced.
