Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen foldable display devices face challenges in quickly making applications usable when the device is changed to different opening states, requiring user input and complex processing.
Innovation Solution
A dual-screen display device with a detection unit and display control unit that automatically adjusts the display of applications based on the degree of opening and tilt of the device, allowing for quick access to relevant apps by detecting specific states and displaying corresponding images on the screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the device automatically detects device state and displays corresponding application images, then application accessibility speed is improved, but device complexity increases due to detection unit and display control unit requirements
Solution Approach 1:
The system pre-associates application images with specific device states (opening degrees and tilt angles) in advance. When a state is detected, the corresponding application image is immediately displayed without requiring user selection or complex real-time processing, thus reducing access time while managing complexity through pre-computation
Solution Approach 2:
The device automatically detects its own state (opening degree and tilt angle) and autonomously determines which application image to display based on pre-established associations. This self-service mechanism eliminates the need for manual user input and reduces the complexity of external control systems
2Measurement precision
If multiple detection parameters (opening degree and tilt angle) are monitored to determine device state, then application selection accuracy is improved, but measurement complexity increases
Solution Approach 1:
The detection process is segmented into distinct parameters: opening degree detection and tilt angle detection. Each parameter is detected independently by dedicated sensors, and the results are combined to determine the overall device state. This segmentation simplifies the detection system by breaking down complex state measurement into manageable independent measurements
Solution Approach 2:
The detection system is designed to measure multiple parameters (opening degree and tilt angle) using a unified state determination framework. The same detection unit and control logic handle both parameters, making the system multi-functional and reducing overall complexity compared to having separate systems for each parameter

AI summary
A display device includes a main body degree of opening detecting unit that detects that a degree of opening of the main body is in a first style state that satisfies a style condition. A main body tilt detecting unit detects that a tilt of the main body is in a second style state that satisfies a style condition. A dual-screen display control unit, in response to detection that a degree of opening of the main body is in a first style state, and to detection that a tilt of the main body is in a second style state, causes an app image for a first app associated with the style states to appear on a first screen, and causes an app image for a second app associated with the style states to appear on a second screen. A style-based processing execution unit performs processing associated with the style states by use of the apps.
