IR-Guided Display Screen Positioning for Automatic Viewer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen position adjustment devices require manual adjustment or user-operated controllers, lacking an automatic solution to align the display screen optimally with the viewer's position.
Innovation Solution
A motor-driven device with telescopic screws and IR sensors automatically adjusts the screen's position by calculating the swiveling and tilting angles based on IR signal intensity from a remote control unit, allowing for automatic alignment with the viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual adjustment or user-operated controller is used, then device complexity is reduced, but extent of automation deteriorates
Solution Approach 1:
The system uses IR sensors to automatically detect the viewer's position and motor-driven mechanisms to automatically adjust the screen position, eliminating the need for manual operation. The device serves itself by autonomously navigating to the optimal viewing position based on detected IR signals from the remote control unit.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electromechanical system. Motor-driven telescopic screws and rotational mechanisms substitute for manual positioning, while IR sensors and processing units replace human judgment in determining optimal screen orientation.
2Extent of automation
If motor-driven automatic adjustment mechanism is implemented, then extent of automation is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is divided into independent functional modules: telescopic screws for distance adjustment, rotational mechanisms for angle adjustment, IR sensors for detection, and motor-driven actuators for movement. Each component performs a specific function, making the complex system manageable and maintainable.
Solution Approach 2:
The support system incorporates multiple degrees of freedom with motor-driven components that can dynamically adjust the screen position in real-time. The telescopic screws and rotational mechanisms enable continuous movement and positioning adjustments based on detected viewer location.
3Adaptability or versatility
If telescopic screw extraction is increased for larger screens, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system adjusts the extraction length of telescopic screws based on the detected screen size and distance requirements. The motor-driven telescopic mechanism can vary its extension parameter to accommodate different screen dimensions, enabling the same device to adapt to various display sizes without requiring multiple fixed configurations.
