Plastic Guide Rail Height Adjusting Mechanism for Display Stands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjusting structures for display devices are prone to damage from external collisions, have complex assembly, require multiple components and screws, and are unstable due to the weight distribution, which increases manufacturing costs and space usage.
Innovation Solution
A height adjusting structure using a guide rail, a base, and a supporting unit with a coil-type spring and guide unit that allows vertical movement without screws, reducing the number of components and stabilizing the center of gravity closer to the supporting unit, thus enhancing stability and resistance to shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal height adjusting structure with screws is used, then the structure provides stable support, but it becomes susceptible to damage from external collisions and has a complex assembly structure
Solution Approach 1:
The patent changes the material parameter from metal to plastic for the guide rail and guide unit, creating a structure that is more resistant to external shocks while maintaining sufficient mechanical strength through the plastic material properties and structural design
2Strength
If a metal height adjusting structure with multiple components is used, then the structure provides stable support, but it requires more components and has a complex assembly structure
Solution Approach 1:
The patent merges the guide rail and guide unit into a simplified integrated structure made of plastic, reducing the number of separate components needed while maintaining the height adjusting function and structural stability
Solution Approach 2:
The plastic guide rail and guide unit structure serves multiple functions: guiding the vertical movement, providing structural support, and acting as the housing, eliminating the need for separate metal components and covers
3Strength
If a metal height adjusting structure with multiple components is used, then the structure provides stable support, but it takes up a lot of space
Solution Approach 1:
The patent combines multiple functions into the plastic guide rail and guide unit assembly, reducing the overall volume required for the height adjusting mechanism while maintaining structural stability
4Device complexity
If the height adjusting unit is formed on a supporting unit with the center of gravity forward of the center, then the structure is simple, but the stand becomes unstable due to the weight of the display device
Solution Approach 1:
The patent changes the position parameter of the center of gravity from forward of the supporting unit center to close to the supporting unit center, achieving better stability while maintaining structure simplicity through the plastic guide rail and guide unit design
