Rotatable Dual-Screen Handheld Device for Compact Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic communication devices face challenges in optimizing screen space and user input due to their compact size, particularly in devices with touch-sensitive displays, where functions and operations require adaptable screen content and efficient input methods.
Innovation Solution
A handheld electronic communication device with a rotatable display system featuring two screens, where the first screen faces one direction and the second, larger touch-sensitive screen faces the opposite direction, allowing for different operational modes by activating or deactivating touch-sensing based on the display's position, enabling efficient use of space and input options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single touch-sensitive display is used in a compact handheld device, then the device maintains a small form factor for portability, but the screen space and input area are limited
Solution Approach 1:
The display system is segmented into two separate display screens (first display screen and second display screen) that can be positioned at different locations on the device. This allows the device to maintain a compact form factor while providing additional screen space through the second display screen that can be viewed from the back or side of the device.
Solution Approach 2:
The patent utilizes the third dimension by placing a display screen on the back surface of the device body. Instead of expanding the device horizontally or vertically, the second display screen extends the display area into the depth dimension, allowing users to view additional content without increasing the device's footprint.
2Area of stationary object
If a larger display screen is added to increase screen space, then the display area is improved, but the device becomes less portable
Solution Approach 1:
The display functionality is divided between two separate screens, allowing the main front display to remain compact for portability while the second display provides additional screen real estate on the back surface without requiring the device body to be larger.
Solution Approach 2:
The second display screen is positioned on the back surface of the device, utilizing the z-dimension (depth) rather than expanding the x or y dimensions. This allows increased total display area while maintaining a compact device form factor suitable for handheld use.
3Adaptability or versatility
If the display device is made rotatable to provide adaptable screen orientation, then the versatility and usability are improved, but the device complexity increases
Solution Approach 1:
The display device is made rotatable relative to the device body, allowing it to rotate between a first position where the first display screen faces forward and a second position where the second display screen faces forward. This dynamic reconfiguration enables the device to adapt to different usage scenarios without requiring multiple separate devices or complex adjustable mechanisms.

AI summary
A handheld electronic communication device including a body including an input device facing a first direction, and a display device coupled to the body. The display device has a first display screen and a second display screen. The second display screen faces an opposite direction as the first display screen. The display device is rotatable between a first position in which the first display screen faces the first direction, and a second position in which the second display screen faces the first direction.
