Multi-Arm Display Mount for Adjustable Viewing Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have fixed support structures that make it difficult to adjust the height, distance, and tilting angle of the screen relative to the user's eyes, leading to inconvenience and fatigue during use.
Innovation Solution
A display device with a support system that includes a mounting bracket, tiltable and rotatable arms, and a pillar with elastic members, allowing for adjustable height, distance, and tilting angle adjustments, providing more than 5 degrees of freedom and reducing the required driving force for adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed support structure is used to mount the display unit, then the structural stability is improved, but the adjustability of height, distance, and tilting angle deteriorates
Solution Approach 1:
The support device transforms from a fixed static structure to a dynamic adjustable structure through multiple arms with rotational joints. The first arm rotates about a first axis, the second arm rotates about a second axis, and the third arm rotates about a third axis, enabling continuous adjustment of the display unit's position and orientation while maintaining structural integrity through controlled mechanical connections
2Adaptability or versatility
If multiple arms with rotational joints are added to achieve adjustable height and tilting angle, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The support device is divided into multiple independent functional segments: a mounting bracket for attachment, a first arm for height adjustment, a second arm for distance adjustment, and a third arm for tilting angle adjustment. Each segment performs a specific adjustment function, allowing the complex adjustment capability to be broken down into manageable, modular components that can be independently controlled and maintained
3Stability of the object's composition
If the display unit is fixed to the support device, then the structural stability is improved, but the ease of operation for adjusting screen position deteriorates
Solution Approach 1:
The mounting system transitions from a rigid fixed connection to a dynamically adjustable connection. The display unit is initially secured to the mounting bracket, but the entire assembly can be repositioned through the rotational movements of the three arms, providing both stable mounting and operational flexibility for adjusting screen position to various viewing angles and distances

AI summary
A display device can include a display; a mounting bracket coupled to a rear surface of the display; a first arm connected to the mounting bracket for tilting the mounting bracket up and down; a second arm connected to an end portion of the first arm and the first arm being configured to rotate based on a first swivel shaft disposed in the second arm; a third arm connected to an end portion of the second arm and rotates based on a second swivel shaft disposed in the third arm; a pillar connected to the third arm and the pillar being configured to move up and down; and a fixing part configured to be fixed to an external object, in which the pillar is connected to an upper surface of the fixing part and rotates based on a third swivel shaft disposed in the fixing part or the pillar.
