Rotating Display Stand With Angle Detection for One-Touch Screen Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices require continuous user input to rotate the screen direction, which is inconvenient, especially when multiple users need to adjust the screen, as the screen often does not align optimally with the user's desired direction.
Innovation Solution
An image display device equipped with a rotating mechanism and an angle detection system, using a potentiometer to detect the screen's angle and allow for quick rotation to desired positions via a remote controller, enabling easy adjustment and storage of multiple screen orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous button pressing is used to rotate the screen direction, then the screen can be rotated to face the remote controller direction, but the operation time and complexity increase for the user
Solution Approach 1:
The system pre-detects the user's position relative to the image display device and automatically determines the optimal screen direction before the user needs to adjust it. This eliminates the need for continuous button pressing by performing the orientation action in advance based on detected user position.
Solution Approach 2:
The image display device automatically adjusts its own screen direction based on detected user position information. The system serves itself by autonomously determining and executing the optimal orientation without requiring continuous user input through button pressing.
2Ease of operation
If the screen faces the remote controller direction, then the rotation control is simple, but the screen may not align optimally with the user's position in multi-user scenarios
Solution Approach 1:
The system incorporates user position detection that provides feedback about where users are located relative to the image display device. This feedback mechanism allows the system to accurately determine the optimal screen direction based on actual user positions rather than just remote controller direction, improving alignment precision.
Solution Approach 2:
The image display device is designed to serve multiple users by detecting and responding to different user positions. The system can adapt its screen direction to accommodate various viewing positions, making it universally applicable to multi-user scenarios rather than being limited to single-user remote controller alignment.

AI summary
A self-supporting stand for a thin display device is to be controlled so that the display device faces in a preset screen direction in a one-touch manner. A function of constantly recognizing the screen direction of the display device and detecting its own direction by detecting a resistance value of a resistance volume such as a variable resistor installed in an electric screen direction changing mechanism, and a control unit which reproduces a preset screen direction no matter in which direction the screen faces currently, are combined with each other.
