Dual-Screen Mobile Terminal with Segmented Input and Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals require users to change the way they hold the device depending on whether button presses or touch inputs are needed, making it inconvenient for multi-input tasks.
Innovation Solution
A mobile terminal design with dual displays on the front and rear surfaces that allows output to switch between displays when opened, enabling touch inputs on one display to execute functions on the other, allowing for multi-input methods while maintaining a consistent holding position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user presses buttons for key input, then the user can input keys tactilely, but the user must change the way of holding the terminal
Solution Approach 1:
The terminal is divided into two separate bodies (first body and second body) that can be opened relative to each other. The first display unit is disposed on the first body while the second display unit is disposed on the second body, allowing independent positioning of input and output interfaces.
Solution Approach 2:
The patent introduces a spatial dimension by opening the first body relative to the second body. When opened, the first display unit and second display unit are positioned in different spatial planes, allowing the user to view the output display while maintaining a stable holding position for button input.
2Ease of operation
If the user performs touch screen inputs, then the user can input keys through touch operation, but the user must change the way of holding the terminal
Solution Approach 1:
The terminal interface is segmented into separate input and output zones on different bodies. The touch input can be performed on the first body while the output is displayed on the second body, allowing consistent two-handed holding position regardless of input method.
Solution Approach 2:
The first display unit serves multiple functions: it can display information directly and also serve as a touch input interface. The controller can receive touch inputs from the first display unit and execute corresponding functions, making the same display surface both input and output device.
3Adaptability or versatility
If the terminal has both button and touch input capabilities, then the user can choose different input methods, but the user must change holding position depending on input method
Solution Approach 1:
By separating the input interface (first display unit on first body) and output interface (second display unit on second body) into different physical locations, the user can maintain a consistent two-handed holding position whether using button input or touch input, eliminating the need to switch between one-handed and two-handed holding modes.

AI summary
A mobile terminal, method and computer program product for transferring a currently displayed first display from a first touchscreen of a first display unit on an outer surface of a first body of a device to a second display unit on an inner surface of the first body or on an inner surface of a second body of the device when the device is opened, and subsequently executing a predetermined function upon receiving a first touch input to the first touchscreen.
