Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle with easily changing screen direction between horizontal and vertical orientations due to difficulty in adjusting stands, leading to instability and inconvenience.
Innovation Solution
A display device with a rotation driver system that adjusts stand angles during module rotation, featuring a main body gear, reverse gear, and stand gears, with a gear ratio of 3:1, allowing for stable switching between horizontal and vertical orientations without additional stand adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen direction is changed to vertical or horizontal, then the display can be optimized for different viewing needs, but the stand is not easily adjusted and it becomes difficult to exchange between horizontal and vertical types
Solution Approach 1:
The patent combines the rotation function and stand angle adjustment function into a single rotation driver assembly. When the display module rotates, the stand angle automatically adjusts through the integrated gear mechanism, eliminating the need for separate stand adjustments and making the switching between horizontal and vertical orientations easy and convenient.
Solution Approach 2:
The rotation driver automatically adjusts the stand angle based on the rotation position of the display module. The mechanical linkage through gears causes the stand to self-adjust to the appropriate angle without requiring manual intervention, allowing the system to serve itself during the orientation switching process.
2Adaptability or versatility
If a fixed stand structure is used, then the device structure is simple, but it is difficult to adjust the stand angle when rotating the display module
Solution Approach 1:
The patent merges the rotation driver with the stand support structure, creating an integrated assembly where the gear mechanism serves dual purposes: rotating the display module and adjusting the stand angle. This combination adds adaptability while keeping the overall structure compact and unified rather than adding separate complex adjustment mechanisms.
Solution Approach 2:
The rotation driver performs multiple functions simultaneously: it rotates the display module to change orientation and automatically adjusts the stand angle to maintain stability. This multi-functionality provides adaptability for different viewing orientations without requiring separate dedicated mechanisms for each function.
3Reliability
If the stand height remains fixed during rotation, then the structure is simple, but the display module may hit the floor and cannot rotate stably
Solution Approach 1:
The stand height adjustment is merged into the rotation driver mechanism. As the display module rotates, the gear-driven stand automatically changes height to ensure the module clears the floor and maintains stable rotation, eliminating the need for separate height adjustment controls or mechanisms.
Solution Approach 2:
The stand height is made dynamic rather than fixed, automatically changing according to the rotation position of the display module. This dynamic adjustment ensures that during rotation, the stand height increases to prevent the module from hitting the floor, and stabilizes at the appropriate height when rotation is complete, providing reliable rotation stability.
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 easy and stable switching of screen direction, maintaining optimal height and stability during rotation, with the center of gravity remaining below the combined stand and module, ensuring stable support.
Implementation Method 1
The rotation driver may include a main body gear rotating together with the display module, a reverse gear rotating in engagement with the main body gear, a first stand gear rotating in engagement with the reverse gear, and a second stand gear rotating in engagement with the first stand gear

AI summary
A display device is characterized by comprising: a display module for outputting an image; a rotation drive unit located on the rear surface of the display module; and a pair of stands extending obliquely downward from the rotation drive unit, wherein the rotation drive unit adjusts the angle of the stands simultaneously when the display module rotates. In the display device, the direction of the display module can be easily changed, and thus it is easy to change the display module according to the arrangement of the screen being output.
