Solution Overview

Problem

In multi-display environments, such as those involving internal and external screens of varying sizes, existing technologies fail to synchronize the homescreen layout consistently, leading to inconsistent item arrangements and unnatural configurations due to differing display sizes and ratios.

Innovation Solution

An electronic device with a display module and processor that switches between display screens by outputting a first view layout on a second display screen with a greater area, grouping page layouts, and detecting a screen switch input to transition to a second view layout based on the number of pages displayable on the second screen, maintaining a consistent user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate grids or data are managed for each display screen, then each screen can be configured independently, but consistency and synchronization between screens deteriorates

Engineering Contradiction:

ImproveIndependent screen configurationVSAvoidHomescreen layout consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The display screen is divided into multiple regions (first region and second region) with different aspect ratios. Each region can be independently configured with appropriate layouts, while the system manages these segmented regions through a unified homescreen data structure that maintains overall consistency. This allows independent optimization for each screen size while preserving synchronization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts layout parameters such as grid size, icon size, and item arrangement based on the detected display screen characteristics. When switching between different display screens, the processor modifies these parameters to achieve natural configurations for each screen size while maintaining a consistent homescreen identity across all displays.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If the same grid size or icon size is used across different display screens, then configuration simplicity is maintained, but natural configuration deteriorates due to different screen ratios

Engineering Contradiction:

ImproveConfiguration managementVSAvoidNatural screen configuration

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

Different regions of the display system are assigned different local qualities - specifically, different grid sizes and icon sizes tailored to each screen's aspect ratio and size. The first region and second region can have independently optimized layouts that naturally fit their respective display characteristics, rather than forcing a uniform configuration across all screens.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts configuration parameters based on the active display screen. When the processor detects a screen switch, it automatically modifies grid size, icon size, and item arrangement to match the characteristics of the current screen, providing natural configurations without requiring manual reconfiguration by the user.

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If item arrangement is performed manually for each display size, then customization precision is improved, but user operation complexity increases

Engineering Contradiction:

ImproveItem arrangement precisionVSAvoidUser operation simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs self-service by automatically detecting the active display screen and adjusting item arrangements accordingly. The processor monitors screen switches and autonomously reconfigures the homescreen layout, grid size, and icon sizes without requiring manual user intervention. This provides precision optimized for each screen size while maintaining operational simplicity for the user.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If separate homescreen configurations are used for internal and external screens, then screen-specific optimization is achieved, but synchronization and continuity deteriorate

Engineering Contradiction:

ImproveScreen-specific optimizationVSAvoidHomescreen synchronization

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system implements a universal homescreen data structure that serves multiple display screens with different characteristics. This unified data structure enables the same homescreen content to be adaptively rendered across various screen sizes and aspect ratios, maintaining synchronization and continuity while allowing screen-specific optimizations through dynamic parameter adjustment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An electronic device outputs, on a second display screen, a page layout output on a first display screen along with another page layout grouped together with the page layout in response to a screen switch from the first display screen to the second display screen having a greater display area than a display area of the first display screen, and switches the grouped page layouts in response to a swipe input being detected.
