Solution Overview

Problem

Existing methods for cross-ecosystem application window display on terminal devices result in significant time delays and poor user experience due to the need for complete window information transmission and separate management of application windows across different operating systems, leading to freezes and performance issues.

Innovation Solution

A method where the first operating system controls the application to send only description information of the window information, reducing the need for memory read and write operations and bandwidth usage, and implementing a unified management of application windows, thereby minimizing time delays and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complete window information is transmitted from the virtual machine to the host operating system, then cross-ecosystem window display is achieved, but transmission time delay increases significantly

Engineering Contradiction:
Improvecross-ecosystem window display capabilityVSAvoidwindow display time delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent extracts only the essential description information from complete window information for transmission. Instead of transmitting the entire window information structure, the system identifies and transmits only the critical description fields that enable window rendering, thereby reducing transmission time delay while maintaining cross-ecosystem display capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments window information into description information (transmitted) and detailed content (locally accessed). This segmentation allows the system to transmit minimal necessary data for window creation while the host operating system accesses additional details locally, reducing overall transmission time

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If complete window information is transmitted across systems, then window display is achieved, but transmission bandwidth consumption increases

Engineering Contradiction:
Improvecross-system application displayVSAvoidtransmission bandwidth usage
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential description information from complete window information for transmission. Instead of transmitting the entire window information structure, the system identifies and transmits only the critical description fields that enable window rendering, thereby reducing transmission bandwidth consumption while maintaining cross-ecosystem display capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a reference copying mechanism where description information acts as a pointer or reference to the actual window information stored locally. This allows the system to transmit minimal reference data rather than complete window information, significantly reducing bandwidth usage while enabling access to full window content

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If separate management of application windows is implemented across different operating systems, then cross-ecosystem compatibility is achieved, but system complexity increases

Engineering Contradiction:
Improvecross-ecosystem compatibilityVSAvoidwindow management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges window management by having the host operating system create and manage windows uniformly, regardless of whether the application originates from the same or different ecosystem. The container-managed application and host operating system cooperate through standardized interfaces, consolidating window management responsibilities and reducing system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal window management approach where the host operating system's window management mechanisms handle applications from multiple ecosystems through a common interface. The description information format and window creation process are standardized, allowing the same window management infrastructure to serve multiple purposes and ecosystems

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