Dual-Screen Mobile Phone with Segmented Display and Keypad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone devices face challenges in providing a large, easy-to-read screen with a full keypad for efficient text entry while maintaining a small form factor, as touchscreen devices lack tactile feedback and have smaller screens, and devices with moveable parts are unreliable and costly.
Innovation Solution
A mobile phone device with a rectangular enclosure featuring a first side entirely or mostly occupied by a touchscreen display and a second side with a physical keypad and display, allowing data output on both sides and detecting reorientation to switch between them for optimal usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a touchscreen display is used, then the screen size can be large and easily viewable, but text entry efficiency deteriorates due to lack of tactile feedback
Solution Approach 1:
The device is divided into two separate sides: one side dedicated to a large touchscreen display for viewing, and the other side dedicated to a physical keypad for text entry. This segmentation allows each side to optimize its function without compromise - the touchscreen can be large and viewable while the physical keypad provides tactile feedback for efficient text entry.
2Productivity
If an LCD display with full keypad is used, then text entry efficiency improves with tactile feedback, but screen size deteriorates and becomes smaller and harder to view
Solution Approach 1:
The device separates the display function and input function into different sides. The LCD with full keypad is placed on one side providing excellent text entry efficiency, while a separate display is provided on the other side that can be optimized for viewing without being constrained by keypad space requirements.
3Area of moving object
If moveable screens or keypads are added to provide larger display with full keypad, then screen size and text entry capability improve, but device reliability deteriorates due to additional moving parts
Solution Approach 1:
Instead of making the screen or keypad moveable to accommodate both functions in one side, the invention inverts the approach by making the entire device body the movable element. The phone can be flipped over to access different sides, with each side containing fixed, non-moving components optimized for their specific function.
4Productivity
If moveable screens or keypads are added to provide larger display with full keypad, then text entry capability improves, but device complexity and cost increase
Solution Approach 1:
Rather than adding complex moveable mechanisms to integrate screen and keypad in one side, the invention simplifies the design by using fixed components on each side and making the entire device flip the simpler mechanical operation.
5Area of moving object
If moveable screens or keypads are added to provide larger display with full keypad, then a larger screen with full keypad can be included, but device thickness increases and form factor deteriorates
Solution Approach 1:
Instead of extending the device in one direction to accommodate moveable components, the invention uses a compact thin form factor where both the large display and full keypad are accommodated on opposite faces of the same thin body, allowing the device to fit easily in pockets while providing both functions.

AI summary
According to one embodiment, a mobile phone device includes a generally rectangular-shaped enclosure, the enclosure including a first side on an opposite side of the enclosure from a second side. The first side has a first display that occupies between about 60 percent and about 100 percent of the first side, and the second side has a keypad and a second display. In another embodiment, a method includes outputting data on a first display of a mobile phone device, wherein the first display occupies between about 60 percent and about 100 percent of the first side, detecting a reorientation of the mobile phone, and outputting data on a second display on a second side of the mobile phone device, wherein the first side is opposite the second side, wherein the second side includes a keypad and the second display. Other embodiments are disclosed as well.
