Solution Overview

Problem

Modern electronic devices with increasing screen-to-device ratios face challenges in providing intuitive and efficient user interaction, particularly in transitioning content between multiple or wrap-around displays, leading to potential unintended touch events and complexity in user experience.

Innovation Solution

The implementation of device rotation, user actuation targets, and double taps on inactive displays allows for seamless switching of content between displays or display portions, utilizing motion sensors and processors to detect gestures and user inputs, thereby deactivating unused displays and enhancing user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the screen-to-device ratio is increased to provide more display area, then the display area is improved, but the device becomes more prone to unintended touch events and harder to control intuitively

Engineering Contradiction:

Improvedisplay areaVSAvoidintuitiveness of control

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The display is segmented into multiple independent display areas (front display and rear display) that can be independently activated. The system divides the display functionality so that different content can be presented on different surfaces, and the user can selectively activate only the needed display area, reducing unintended touches on inactive surfaces while maintaining large total display area.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple displays are added to provide more content presentation options, then the versatility is improved, but the device complexity increases

Engineering Contradiction:

Improvecontent presentation optionsVSAvoidnumber of displays

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rear display serves multiple functions: it can display content independently, show notifications, provide quick access to frequently used functions, or remain inactive to save power. The same hardware infrastructure supports multiple operational modes, allowing the system to be versatile without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system pre-configures the rear display with common functions and shortcuts that are activated through simple gestures or touches. This preliminary setup allows users to access frequently used features without navigating through complex menus, reducing the perceived complexity while maintaining versatility.

Inventive Principle:

Principle #10Preliminary action

3Shape

If touch-sensitive displays are used to replace physical keypads, then the sleekness and modern design are improved, but the precision and reliability of input decreases

Engineering Contradiction:

Improvesleekness of designVSAvoidinput precision

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

Different regions of the touch-sensitive display have different sensitivities and response characteristics optimized for their specific functions. Critical input areas have enhanced precision detection, while decorative or informational areas have lower sensitivity to prevent false inputs. This local optimization maintains sleek design while improving input reliability where needed.

Inventive Principle:

Principle #3Local quality

AI summary

An electronic device includes a first touch sensitive display positioned on a first major surface of the electronic device and a second touch sensitive display positioned on a second major surface of the electronic device, or alternatively a single display wrapping about the first major surface and the second major surface. One or more processors cause a presentation of content on the first touch sensitive display while the one or more sensors receive user input. In response to the user input, which can be received by the second touch sensitive display, the one or more processors cease the presentation of the content on the first touch sensitive display and commence another presentation of the content on the second touch sensitive display. The process is reversible to send the content back to the first touch sensitive display.
