Optical Hinge Angle Sensing for Automatic Dual-Display Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require manual user adjustment of brightness, contrast, and volume settings when multiple displays are angled relative to each other, lacking automatic control based on the display angle.
Innovation Solution
A hinge device with a light emitter and receiver on opposing hinge portions that control connected displays based on light intensity, allowing automatic adjustment of display settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are connected using a hinge device, then the displays can be positioned at different angles to serve different purposes, but the user must manually adjust brightness, contrast, and volume settings for each angle configuration
Solution Approach 1:
The system automatically detects the hinge angle using a sensor and adjusts display parameters (brightness, contrast, volume) without requiring user intervention. The display device performs the adjustment operation itself based on the detected angle, eliminating manual configuration needs.
Solution Approach 2:
A sensor continuously monitors the hinge angle and provides feedback to the controller, which then automatically adjusts display settings based on the detected angle. This closed-loop feedback mechanism enables automatic adaptation to different display configurations.
2Adaptability or versatility
If a hinge device mechanically connects multiple displays, then the displays can be folded and positioned flexibly, but additional components like light sensors and controllers must be integrated into the hinge structure
Solution Approach 1:
The hinge device is designed to perform multiple functions: mechanical connection and folding of displays, angle detection via sensor, and automatic control of display parameters. By integrating these functions into a single hinge unit, the overall system complexity is managed efficiently.
Solution Approach 2:
The sensor, controller, and hinge mechanism are combined into an integrated unit. The sensor is mounted on the hinge portion, and the controller is configured to receive sensor signals and control display parameters, merging multiple components into a compact assembly.
3Extent of automation
If the hinge angle is used to control display parameters automatically, then user convenience is improved, but the hinge structure must include precise sensing and control mechanisms
Solution Approach 1:
The manual mechanical adjustment process is replaced with an automated system using a sensor to detect the hinge angle and a controller to adjust display parameters electronically. This substitution of mechanical control with sensor-based automatic control improves convenience while managing complexity through integration.
