Rotating Flip Keyboard for Compact Mobile Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile devices face challenges in providing an effective user interface for both voice and text transmission due to limited space, leading to unsatisfactory input methods for advanced functionalities like email and internet browsing.
Innovation Solution
A flip-around keyboard design that is rotatably coupled to the housing, allowing for a compact device with a large display screen, featuring keys with translucent indicia and adjustable display light intensity for improved usability in low-light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard size is increased to provide effective text input for advanced functionalities, then the user interface functionality is improved, but the device size increases
Solution Approach 1:
The keyboard is designed to be rotatable relative to the display screen, allowing it to dynamically change position between covering and non-covering states. This dynamic configuration enables the keyboard to provide full input functionality when needed while maintaining a compact form factor by tucking away when not in use.
Solution Approach 2:
The keyboard is positioned in a different spatial dimension relative to the display, rotating on an axis that allows it to overlay the display when needed. This dimensional arrangement enables the keyboard to occupy space efficiently without permanently increasing the device's footprint.
2Adaptability or versatility
If the display screen size is increased to accommodate multimedia and internet functions, then the user interface functionality is improved, but the space available for input devices decreases
Solution Approach 1:
The keyboard rotates to overlay the display screen only when text input is required, allowing the display to maintain its full size for multimedia and internet functions while providing access to a full keyboard when needed.
Solution Approach 2:
The device is segmented into two main functional components: a fixed display area for multimedia and internet functions, and a rotatable keyboard component for text input. This segmentation allows each component to optimize its function without compromising the other.
3Volume of moving object
If the keyboard is made compact to maintain small device size, then the device portability is improved, but the user interface functionality for text input deteriorates
Solution Approach 1:
The keyboard rotates into position over the display to provide full-sized key input functionality when text entry is required, while maintaining a compact profile when rotated away, thus providing both portability and full input capability.

AI summary
A mobile device having a flip-around keyboard includes a housing, a display, and a keyboard rotatably coupled to the housing. The housing has a top end, a bottom end, a front surface, and a back surface. The display is located on the front surface of the housing. The keyboard is rotatably coupled at about the bottom end of the housing. The keyboard has a front face having a plurality of keys and a rear face opposite the front surface. In a first configuration, the rear face of the keyboard faces the display of the housing. In a second configuration, the front face of the keyboard faces the back surface of the housing. The keyboard can be rotatably coupled to the housing by a coupler that permits greater than two hundred seventy degrees of rotation about a lateral axis parallel to an edge of the housing.
