Mobile Terminal Wallpaper Management via Feature Matching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In mobile terminals, setting a wallpaper often results in inconsistencies between the user-selected wallpaper status and the system status due to multi-thread switching and various wallpaper setting sources, requiring additional user confirmation and lengthening the process.

Innovation Solution

A wallpaper management method and apparatus that determines the wallpaper to be switched, obtains and compares feature information with a feature database to find a matching wallpaper, and performs switching based on this information, ensuring consistency and eliminating the need for additional user confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional wallpaper setting procedures with multiple information transfer parameters are used, then wallpaper status consistency can be monitored, but the process becomes complex and requires additional user confirmation

Engineering Contradiction:

Improvewallpaper status consistencyVSAvoidprocedure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where the application monitors system wallpaper status changes through callbacks and broadcasts, comparing the actual system status with the application-recorded status to ensure consistency and trigger appropriate updates

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary module that acts as a bridge between the application and system wallpaper settings, managing information transfer through standardized parameters and callbacks to reduce procedural complexity while maintaining reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multi-thread switching and various wallpaper setting sources are supported, then user flexibility is improved, but status inconsistency between application and system occurs

Engineering Contradiction:

Improvewallpaper setting flexibilityVSAvoidwallpaper status consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system continuously monitors wallpaper status changes through feedback mechanisms including callbacks and broadcast receivers, comparing expected status with actual system status to detect and correct inconsistencies caused by multi-thread switching and multiple setting sources

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The application performs self-service by automatically detecting status inconsistencies and triggering wallpaper updates without requiring user intervention, using internal logic to reconcile differences between application-recorded status and system actual status

Inventive Principle:

Principle #25Self-service

3Reliability

If additional confirmation steps are added to ensure wallpaper status consistency, then reliability is improved, but user operation time increases

Engineering Contradiction:

Improvewallpaper status consistencyVSAvoiduser confirmation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs automatic self-service by monitoring its own wallpaper status through callbacks and broadcasts, detecting inconsistencies and triggering updates autonomously without requiring user confirmation, thus maintaining reliability while eliminating time loss

Inventive Principle:

Principle #25Self-service
