Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld computing devices with single touch screen displays face challenges in balancing display graphics and input areas, leading to visual clutter and user frustration due to their limited screen space, which hampers information interpretation and productivity.
Innovation Solution
A dual multi-display handheld computing device with two touch-sensitive screens that can be oriented and configured in various positions to provide enhanced display configurations and input options, allowing for improved user interaction and productivity by expanding the display area and optimizing user interface layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single touch screen display is used in handheld computing devices, then the device maintains a compact form factor, but the display area is limited causing visual clutter and reduced user productivity
Solution Approach 1:
The display system is segmented into multiple independent touch-sensitive screens that can be positioned in various configurations. Each screen can display different content simultaneously, eliminating visual clutter while providing extensive display area. The screens can be arranged in portrait, landscape, or split orientations to optimize the display real estate without increasing the handheld device's form factor complexity.
2Productivity
If multiple displays are added to increase display area, then user productivity and information interpretation improve, but the device complexity and space requirements increase
Solution Approach 1:
Instead of expanding display area in a single plane, the system utilizes multiple dimensional arrangements of touch-sensitive screens. The screens can be positioned at different angles and orientations (portrait, landscape, split), effectively using spatial dimensions to maximize display area within the handheld device's form factor. This dimensional approach enhances productivity by providing more screen real estate without proportionally increasing device complexity.
3Ease of operation
If virtual keypads and user interface elements are superimposed on the display, then input functionality is provided, but the display area for information interpretation is reduced
Solution Approach 1:
The display system is divided into multiple independent touch-sensitive screens that can be allocated for different functions simultaneously. One or more screens can be dedicated to displaying information while another screen handles virtual keypads and user interface elements. This segmentation allows full utilization of display area for information interpretation while maintaining complete input functionality on separate screen regions.

AI summary
A multi-display device can interface with two or more different types of docking stations. The device can determine the type of dock and change the pin outs for a connector to interface with that dock. Once docked, the device can determine a charge status for the device and the dock to present the status to the user. Further, the dock can enter one of several modes, including a call receipt mode and an entertainment mode. The modes allow for expanded functionality for the device while docked. Two particular docks, the laptop dock and the smart dock, provide special functionality with the device.
