Motorized Hinge Display Viewing Angle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information handling systems with automated opening mechanisms often leave the display offset from the user's optimal viewing angle, requiring manual adjustments to ensure clear and contrast-rich visuals, even after automated opening.
Innovation Solution
A system with motorized hinges and sensors, such as eye gaze sensors, that automatically adjust the display orientation to maintain a perpendicular viewing angle relative to the user, allowing for continuous optimal viewing without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated opening mechanism is used to open the lid housing portion, then end user convenience is improved, but display viewing angle alignment deteriorates
Solution Approach 1:
The system uses sensors to detect user position and automatically adjusts the display angle without requiring manual intervention. The motorized hinge self-regulates the display orientation based on real-time user positioning data, eliminating the need for users to manually adjust the display while maintaining optimal viewing angles.
Solution Approach 2:
The system incorporates sensors that continuously monitor user position and provide feedback to the control mechanism. Based on this feedback, the motorized hinge dynamically adjusts the display angle to maintain optimal perpendicular viewing alignment, resolving the contradiction between automated operation and viewing angle precision.
2Extent of automation
If motorized hinge automatically opens to a defined orientation, then system automation is improved, but display viewing angle precision deteriorates
Solution Approach 1:
The display orientation is made dynamic rather than fixed. The motorized hinge continuously adjusts the display angle based on real-time user position detection, allowing the system to maintain optimal viewing angles across different user positions and environments while remaining fully automated.
Solution Approach 2:
The patent replaces fixed mechanical positioning with an automated sensor-motor control system. Sensors detect user position and electronically control the motorized hinge to achieve precise display angle alignment, substituting rigid mechanical design with flexible electronic control for improved precision.
3Speed
If display is positioned for automated viewing, then opening speed is improved, but viewing angle adaptability deteriorates
Solution Approach 1:
The system maintains continuous useful action by constantly monitoring user position and adjusting the display angle throughout the user interaction session. This continuous adjustment ensures optimal viewing angles are maintained regardless of user movement or environmental changes, providing both speed and adaptability.

AI summary
A portable information handling system rotates a lid housing portion integrating a display from a closed to an open position with a motorized hinge. One or more sensors monitor an end user position during the rotating from the closed to the open position so that the motorized hinge aligns the display with a desired viewing position relative to the end user, such as substantially perpendicular to the end user's gaze. The one or more sensors monitor the end user during usage of the information handling system to adjust the motorized hinge as the end user's position changes relative to the display over time.
