Motorized Display Height and Stand Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Desktop computers are bulky and difficult to move, and their external display devices are restricted by cable length, making them less portable and inconvenient to adjust, especially for AIO PCs which are heavy and require cumbersome stand adjustments.
Innovation Solution
An electronic device with a main body, display, stand, height-adjusting module, and angle-adjusting module, where the display is slidably mounted on the main body, and the stand is pivoted, allowing for motor-driven adjustments of the display's height and the stand's angle using stepper motors and transmission units, enhancing usability and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stand is made adjustable for different tilt angles, then user comfort is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The stand is designed with a pivot connection to the main body, allowing it to rotate and adjust to different tilt angles dynamically. This dynamic structure enables the stand to adapt to various viewing positions while maintaining structural integrity through the pivot joint mechanism.
Solution Approach 2:
The stand adjustment function is separated into distinct components: the pivot connection point on the main body, the stand arm, and the display mounting portion. This segmentation allows each component to perform its specific function independently, simplifying the overall adjustment mechanism while maintaining versatility.
2Volume of moving object
If the display is made slidable on the main body for height adjustment, then portability and space efficiency are improved, but the stability of the display position may deteriorate
Solution Approach 1:
The display is connected to the main body through a slidable mechanism that allows vertical movement. This dynamic connection enables the display to be adjusted to different heights and positions, optimizing both compactness when collapsed and viewing comfort when extended, while maintaining stable positioning through friction or locking features in the sliding mechanism.

AI summary
An electronic device includes a main body, a display, a stand, a height-adjusting module and an angle-adjusting module. The display is slidably disposed on the main body. The stand pivots to the main body. The height-adjusting module is disposed on the main body and connected to the display. The angle-adjusting module includes a first sliding element, a linkage, two angle-adjusting transmission units and an angle-adjusting motor. The first sliding element is slidably disposed on the main body. Two opposite ends of the linkage are pivoted to the first sliding element and the stand. The two angle-adjusting transmission units are disposed on the main body and the first sliding element, and engaged with each other. The angle-adjusting motor is connected to the second angle-adjusting transmission unit.
