Display Stand Guide Rail Structure for Stable Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjusting structures for display devices are prone to damage from external collisions, have complex assembly structures, require multiple components and screws, and are unstable due to an offset center of gravity, leading to increased manufacturing costs and space usage.
Innovation Solution
A height adjusting structure using a guide rail and a coil-type spring with a guide unit, where the guide unit moves along the guide rail to adjust the display device's height, eliminating the need for screws and minimizing components, while keeping the center of gravity close to the supporting unit for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal height adjusting structure with screws is used, then the structure is strong and stable, but it is 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 strength through optimized geometric parameters and structural design
Solution Approach 2:
The patent removes screws and fastening components from the structure, extracting the complex assembly elements while maintaining structural integrity through the integrated guide rail and guide unit design that relies on friction and geometric constraints rather than mechanical fasteners
2Stability of the object's composition
If multiple components and screws are used for the height adjusting structure, then the structure is stable, but the manufacturing cost increases and assembly becomes complex
Solution Approach 1:
The patent merges the guide rail, guide unit, and height adjustment mechanism into an integrated structure where the guide unit moves along the guide rail without separate fasteners, reducing the number of components and simplifying assembly while maintaining structural stability
Solution Approach 2:
The guide rail and guide unit serve multiple functions simultaneously: they guide the vertical movement, provide structural support, enable height adjustment, and eliminate the need for separate fastening mechanisms, thereby reducing overall device complexity
3Ease of operation
If the height adjusting unit is formed on a supporting unit erected on a base unit, then the display device can be adjusted in height, but the center of gravity is disposed forward of the center of the supporting unit causing instability
Solution Approach 1:
The patent inverts the traditional height adjustment mechanism by positioning the guide unit to move along the guide rail in a configuration that places the center of gravity closer to or directly over the supporting unit's center, reversing the unstable arrangement and achieving both adjustability and stability
4Reliability
If a separate component is required to cover the sliding assembly and height adjusting unit, then the internal components are protected, but more components are needed and manufacturing cost increases
Solution Approach 1:
The patent merges the protective cover function with the existing guide rail and guide unit structure, where the guide rail itself serves as both a functional component and a protective element, eliminating the need for a separate cover component
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a simpler, cost-effective, and shock-resistant height adjustment mechanism that reduces noise and assembly complexity, while ensuring the display device's stability by maintaining the center of gravity close to the supporting unit, thus preventing instability and damage from external shocks.
Implementation Method 1
a spring, one end of which is fixed to the rear surface fixing unit and the other end contacts the guide unit, so that the spring expands and contracts as the height of the display device is adjusted
