Slide Type Elevating Post for Constant Size and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current elevating posts for displays or work tables suffer from varying installation size and reduced rigidity during static and dynamic transitions, and their exposed components can cause aesthetic issues and potential harm upon collision.
Innovation Solution
A slide type elevating post design featuring a plate that slides within a trough, utilizing a transmission system with a driver and outer tube, maintaining constant size and rigidity, and incorporating closed sections for enhanced strength and secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inner tube is projected from or into an outer tube to achieve elevation, then the elevation function is realized, but the overall installing size varies visibly and rigidity is considerably reduced
Solution Approach 1:
The patent applies nesting by placing the moving assembly containing the plate inside the outer tube. The plate slides within a longitudinal trough formed in the outer tube, allowing elevation while maintaining a compact nested structure that does not visibly change installing size. This resolves the contradiction by enabling elevation function while preserving size consistency.
2Ease of operation
If an inner tube is projected from or into an outer tube to achieve elevation, then the elevation function is realized, but rigidity is considerably reduced
Solution Approach 1:
The patent segments the elevation mechanism into a stationary outer tube and a moving assembly with a sliding plate. The plate is guided by the longitudinal trough and constrained by blocking portions at both ends, creating a segmented structure that maintains rigidity while enabling elevation. This segmentation prevents the rigidity loss associated with telescoping tube designs.
3Ease of operation
If outer tube or inner tube is exposed to achieve elevation, then the elevation function is realized, but appearance is derogated and collision damage may occur
Solution Approach 1:
The moving assembly is nested inside the outer tube, with the plate sliding within the longitudinal trough and remaining concealed during elevation. This nested configuration eliminates exposed moving parts that could cause collision damage or aesthetic issues, while still achieving the elevation function through the sliding mechanism.
4Stability of the object's composition
If a plate slides in a trough to achieve elevation, then installing size and rigidity are kept constant, but assembly complexity increases
Solution Approach 1:
The patent merges the guiding function and the blocking function into the longitudinal trough structure. The trough is formed directly in the outer tube and incorporates blocking portions at both ends that simultaneously guide the plate's movement and prevent it from exiting. This merging simplifies the overall structure despite the sliding mechanism, reducing assembly complexity.

AI summary
An elevating post includes a transmission (10), a driver (20), an outer tube (30) and a moving assembly (40). The driver (20) is connected to the transmission (10). The outer tube (30) receives the transmission (10) and the driver (20) and has a tube body (31) with a longitudinal trough (311). Two closed sections (312, 313) are separately disposed outside two ends of the longitudinal trough (311). The moving assembly (40) is operatably connected to the transmission (10) and has a plate (43) protruding from the tube body (31) by passing through the longitudinal trough (311) and being movable in the longitudinal trough (311).
