Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing cost of existing elevatable stands is high due to their complex assembly processes with numerous components, which complicates the assembly process and results in a bulkier design.
Innovation Solution
A supporting device with a novel structure featuring a shell with protruding ribs, a slider with self-lubricating blocks, and an elastic element, allowing the slider to slide between positions with reduced components and simplified assembly, using a shell with interconnected openings and protruding ribs, and self-lubricating blocks that contact surfaces to facilitate smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linear slide with rolling balls and multiple components is used, then the display device can move smoothly and be sustained at any height, but the manufacturing cost increases and the assembly process becomes complex
Solution Approach 1:
The patent combines multiple functions into the support shell: the shell itself serves as both the structural support and the guide rail (replacing the linear slide's outer rail), while the self-lubricating blocks replace both the ball lining and the elastic element functions. This merging reduces the number of separate components while maintaining smooth movement and height sustainment capabilities.
Solution Approach 2:
The self-lubricating blocks are made of material that provides its own lubrication, eliminating the need for separate elastic elements or ball linings to reduce friction. The blocks automatically provide the necessary low-friction surface against the support shell, simplifying the system while maintaining reliable movement.
2Ease of operation
If multiple components and assembly parts are used, then the display device can be supported and adjusted, but the stand design becomes bulkier
Solution Approach 1:
The support shell integrates the guide structure and support function into a single component, eliminating the need for separate outer rails, inner rails, and mounting brackets. This integration significantly reduces the overall volume of the stand while maintaining full support and adjustment functionality.
3Ease of operation
If a linear slide with ball lining is used, then the slider can move smoothly, but the manufacturing cost increases
Solution Approach 1:
The self-lubricating blocks are made from materials that inherently provide low friction, eliminating the need for precision-machined ball linings or additional lubrication systems. This simplifies manufacturing while maintaining smooth slider movement along the support shell.

Function Achieved in This Case
The solution reduces the number of assembly parts, simplifies the assembly process, and results in a slimmer stand design while maintaining the ability to adjust the display device's height, offering a cost-effective and efficient solution to the complex assembly issues of existing stands.
Implementation Method 1
a slider (2) including a main part (21), an elongated arm (22), and at least one self-lubricating block (23)
Implementation Method 2
an elastic element disposed between the slider and the support; wherein when a force is applied to the slider, the self-lubricating block rubs the support so that the slider slides between a highest position and a lowest position with respect to the support, and the slider stops at any height with respect to the support when the force is removed

AI summary
A supporting device is disclosed, which comprises a support; a slider including at least one self-lubricating block; a pressing block disposed at the second opening, abutting the inner side of the second opening, and fixed on the slider so that the slider may tightly abut against the support through the self-lubricating block; and an elastic element disposed between the support and the slider. When a force is applied to the slider, the slider may move between a highest position and a lowest position with respect to the support while the self-lubricating block rubs the support. When the force is removed, the slider may stop at any vertical height with respect to the support.
