Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in providing efficient user input due to limited space, requiring innovative solutions to enhance usability and reduce power consumption while maintaining portability.
Innovation Solution
A moveable display assembly in portable electronic devices that exposes a touch-sensitive input device on the back when the keyboard is in use, allowing for thumb input and forefinger navigation without repositioning hands, thereby reducing device usage and power consumption.

Engineering Contradiction Analysis
1Weight of moving object
If a touch-sensitive display with limited space is used in portable electronic devices, then portability is improved, but user input efficiency deteriorates
Solution Approach 1:
The patent utilizes the back surface of the display assembly as an additional input dimension. By placing a touch-sensitive input device on the back of the display assembly, the invention creates a second input plane that does not occupy additional space on the front display area, thereby maintaining portability while enhancing user input efficiency through multi-dimensional interaction.
Solution Approach 2:
The display assembly is designed to be movable relative to the body, transitioning between a first position that covers the input device and a second position that exposes it. This dynamic configuration allows the device to adapt between different input modes (keyboard-only, touch-only, or combined), resolving the contradiction by providing context-dependent input efficiency without permanently increasing device footprint.
2Productivity
If the display assembly is made movable to expose input devices, then user interaction efficiency is improved, but device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: a body housing containing the keyboard, and a separate display assembly that can move independently. This segmentation allows the complex movable mechanism to be isolated to just the display assembly portion, rather than requiring the entire device structure to be complex, thereby limiting the increase in overall device complexity while still achieving improved user interaction efficiency.

AI summary
An electronic device includes a body and a display assembly. The display assembly includes a housing, a display on one face of the housing, and a first input device located on an opposing face of the housing, adjacent at least one side of the display assembly. The display assembly is connected to the body and moveable relative to the body, between a first position in which the first input device is covered by the body and a second position in which the input device is exposed.
