Rotating Dual-Leg Display Stand for Easy Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices standing on the floor lack adjustable height options, making it difficult to optimize viewing height for different user positions and environments.
Innovation Solution
A display device with a stand system featuring rotatable hinge brackets and legs of varying lengths, allowing easy adjustment between two states for optimal height positioning without requiring reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stand length is fixed, then the device structure is simple and manufacturing cost is low, but the viewing height cannot be adjusted for different user positions
Solution Approach 1:
The stand is designed with a rotatable hinge bracket that allows dynamic adjustment between two states: a first state where both long and short legs contact the mounting surface for stability, and a second state where only the long leg contacts the mounting surface for extended height. This dynamic mechanism enables viewing height adjustment without complex assembly changes.
2Ease of operation
If the stand structure is made adjustable, then viewing height can be optimized, but the device complexity and manufacturing cost increase
Solution Approach 1:
The stand is segmented into distinct components including a hinge bracket with long leg and short leg, where each segment serves a specific function. The hinge bracket connects to the display device rear surface, and the legs can be independently positioned to achieve different viewing heights through rotation, simplifying the adjustment operation.
Solution Approach 2:
The rotatable hinge bracket provides a simple dynamic mechanism that allows users to switch between two height states by rotation, avoiding complex assembly/disassembly operations while maintaining ease of adjustment.
3Adaptability or versatility
If the stand uses a rotatable hinge mechanism, then height adjustment is enabled, but the stability may be compromised
Solution Approach 1:
The hinge bracket is designed to rotate between two stable states: the first state where both long and short legs contact the mounting surface providing enhanced stability, and the second state where the long leg extends forward for height adjustment. Each state maintains stability through proper geometric configuration.
Solution Approach 2:
The stand employs asymmetric leg lengths with a long leg and short leg configured at a predetermined angle to the display device rear surface. This asymmetric design allows the stand to achieve different stable configurations for height adjustment while maintaining structural balance and stability in each state.
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
Enables simple and effective height adjustment of the display device, improving usability and reducing manufacturing costs while maintaining stability and design simplicity.
Implementation Method 1
a spring located between a head of the bolt and the stand and configured to provide elasticity in a direction in which the stand is attached to the hinge bracket
Implementation Method 2
the stand rotates to change to one state of a first state in which both the long leg and the short leg come into contact with a mounting surface and a second state in which only the long leg comes into contact with the mounting surface

AI summary
A display device comprises: a display module outputting an image; a pair of hinge brackets located on the lower portion of the display module; and a pair of stands which are rotatably coupled to the hinge brackets and each comprise a long leg and a short leg which are extended with a certain angle therebetween, wherein the stand is rotated to transform into one of a first state in which both the long leg and the short leg come into contact with a holding surface and a second state in which only the long leg comes into contact with the holding surface, and thus, the height of the display module is easily switched.
