Solution Overview

Problem

Current electronic devices with multitasking capabilities face limitations due to small screen sizes, making it inconvenient to perform multitasking across multiple applications without splitting the screen, which hampers user experience and application utilization.

Innovation Solution

A multi-display method is implemented using a system of first and second electronic devices, where the first device transmits screen data to the second device, allowing simultaneous use of multiple applications without splitting the screen, maintaining the original application layout and enhancing user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen splitting is used to enable multitasking on mobile devices, then multiple applications can be used simultaneously, but the original application layout and design are compromised due to small screen size

Engineering Contradiction:
Improvemultitasking capabilityVSAvoidapplication utilization
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent extends the display dimension from a single mobile device screen to multiple external display devices. By transmitting screen data to external displays (TVs, monitors, projectors), the system creates additional spatial dimensions for application execution, allowing full-screen applications to run on external displays while the mobile device screen remains available for other tasks or controls.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the display function across multiple devices. The mobile electronic device acts as a control hub while external display devices handle the actual application rendering. This segmentation allows different applications to be distributed across different displays, with each display maintaining its original design intent and screen real estate.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple applications are executed on a single mobile device screen, then multitasking is enabled, but the screen size is insufficient to provide proper application layout and user experience

Engineering Contradiction:
Improvemultitasking efficiencyVSAvoiddisplay area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The system adds spatial dimensions by utilizing external display devices with larger display areas. Instead of compressing multiple applications onto a small mobile screen, the patent distributes applications across multiple displays, including TV screens, computer monitors, and projectors, thereby providing adequate display area for each application while maintaining multitasking capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the mobile device screen is used for single application execution, then the application design is preserved, but multitasking cannot be performed

Engineering Contradiction:
Improveapplication design integrityVSAvoidmultitasking capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The mobile electronic device serves multiple functions: it acts as both a standalone computing device for single-application execution and as a control hub for managing multiple applications across multiple displays. The external display devices also serve dual purposes by displaying application content while allowing the mobile device to remain accessible for other tasks.

Inventive Principle:
Principle #6Universality (Multi-functionality)
