Dual-Display Hinge Posture Detection via Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of dual-display mobile computer devices face discomfort due to the need to adopt suboptimal support and grip positions when interacting with touch-screen displays, as the free half of the device housing may pivot or hang freely, lacking secure detents to maintain a desired display posture.
Innovation Solution
A system that senses position data from a binding or position sensors to determine the angle between the two housings, allowing for the initiation of specific presentation modes based on the display posture, such as laptop, book, presentation, surface, or tablet modes, and provides feedback to maintain secure postures through haptic experiences or detent simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If physical or static detents are used in the hinge to hold the touch-screen displays in a particular display position, then the device can maintain stable display postures, but the device complexity increases and the hinge mechanism becomes more complex
Solution Approach 1:
The patent replaces the traditional mechanical detent system with a software-based solution. Sensors detect the hinge angle and determine display postures, then the operating system automatically configures the user interface accordingly. This substitutes complex mechanical detents with electronic sensing and software control, reducing mechanical complexity while maintaining posture stability.
Solution Approach 2:
The patent implements dynamic posture detection and adaptation. Instead of fixed mechanical detents, the system continuously monitors hinge angle through sensors and dynamically adjusts the display configuration. This allows the device to adapt to various display postures (laptop, book, presentation, surface, tablet modes) without requiring physical detents for each position.
2Device complexity
If the hinge allows free movement without detents, then the device complexity is reduced, but the free half of the device housing may pivot or hang freely causing uncomfortable or suboptimal support and grip positions
Solution Approach 1:
The patent implements feedback through sensors that continuously monitor the hinge angle and provide position data to the system. This feedback mechanism allows the device to detect when it is in a stable posture and automatically configure the interface accordingly, ensuring user comfort without requiring physical detents to prevent free movement.
Solution Approach 2:
The system automatically detects the display posture through sensor data and self-configures the user interface without user intervention. The operating system monitors hinge position and autonomously adjusts the display mode, application layout, and keyboard input methods, allowing the device to serve itself in maintaining optimal operation conditions.
3Adaptability or versatility
If multiple physical detents are added to provide various display positions, then more display postures are supported, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent replaces multiple mechanical detents with a single continuous hinge mechanism配合sensor detection. Instead of manufacturing complex multi-detent hinges, the system uses a simple hinge with electronic sensors to detect and support multiple display postures through software configuration, significantly easing manufacturing while maintaining versatility.
Solution Approach 2:
The patent implements a universal hinge mechanism that can support multiple display postures (laptop, book, presentation, surface, tablet modes) without requiring specific detents for each position. A single hinge design with sensor feedback provides multi-functionality, allowing the same hardware to adapt to various usage scenarios through software rather than requiring separate mechanical solutions for each posture.

AI summary
Embodiments of mobile computer device display postures are described. In embodiments, a first display is integrated in a first housing of a dual-display mobile computer device, and a second display is integrated in a second housing of the dual-display mobile computer device. Position data can be sensed from a binding that movably connects the first housing and the second housing, and a position angle can be determined between the first housing and the second housing that correlates to a display posture of the first display and the second display.
