Pivoting Mobile Device Screen with Gyro Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices have fixed-sized screens, requiring users to purchase multiple devices for different activities, increasing cost and inconvenience.
Innovation Solution
A mobile device design featuring two pivotally connected portions with a hinge, allowing the screen size to be varied between single, dual, and notebook modes by folding or unfolding, utilizing gyroscope sensors to switch between screen configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed size screen is used in a mobile device, then the device structure is simple, but the user cannot adapt the screen size for different activities
Solution Approach 1:
The mobile device is divided into a first portion and a second portion that can be folded relative to each other. The first portion includes a first display and the second portion includes a second display, allowing the screen to be segmented into different visible areas based on the folding state, thereby achieving variable screen size without requiring a completely different device structure for each size.
Solution Approach 2:
The device employs a folding mechanism between the first and second portions that allows the screen configuration to dynamically change between different states (e.g., folded and unfolded). This dynamic structure enables the screen size to adapt from a smaller single-display configuration to a larger dual-display configuration, providing versatility while maintaining a relatively simple base structure.
2Adaptability or versatility
If multiple mobile devices with different screen sizes are purchased for different activities, then the user experience for each activity is optimized, but the cost and convenience are greatly increased
Solution Approach 1:
The mobile device is designed to perform multiple functions by changing its screen configuration. A single device can serve as a small-screen mobile device when folded for activities like web browsing and gaming, and as a large-screen device when unfolded for activities like video watching. This multi-functionality eliminates the need for users to purchase and carry multiple separate devices, reducing both cost and the quantity of devices required.
3Adaptability or versatility
If a variable sized screen is implemented through folding portions, then screen size adaptability is achieved, but the device complexity increases
Solution Approach 1:
The mobile device is divided into a first portion and a second portion that can be folded relative to each other. The first portion includes a first display and the second portion includes a second display, allowing the screen to be segmented into different visible areas based on the folding state, thereby achieving variable screen size without requiring a completely different device structure for each size.
Solution Approach 2:
The device uses gyroscope sensors to automatically detect the folding state and switch between different screen configurations without requiring manual intervention. The system self-adjusts the display mode based on the physical state of the device, reducing the need for complex user interfaces or manual controls while maintaining the variable screen size capability.

AI summary
A mobile device with display screen of more than one size includes a first portion and a second portion. The first portion includes a main screen and a first gyroscope sensor. The main screen is located on a front surface of the first portion. The second portion includes an auxiliary screen and a second gyroscope sensor. The auxiliary screen is located on a front surface of the second portion. The first and second portions are pivotally connected to each other and can be folded or unfolded. The first and second gyroscope sensors can determine the folded and unfolded states of the first and second portions so as to switch the mobile device into a single screen mode of the main screen or a dual screen mode of the main and auxiliary screens.
