Solution Overview

Problem

Existing dynamic wallpapers on electronic devices are limited in user customization, lack interactivity, and fail to provide spatial effects during interface switching, reducing user engagement.

Innovation Solution

A method that allows users to select and customize images for multiple graphic layers, which are processed into a target video using a virtual camera to create dynamic depth effects during interface switching, enhancing interactivity and interest.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a static wallpaper is displayed, then the device complexity is low, but the interactivity and user engagement are reduced

Engineering Contradiction:
ImproveinteractivityVSAvoidwallpaper system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wallpaper is divided into multiple graphic layers, each containing different image elements that can be independently selected and customized by users. This segmentation allows complex interactive functionality while maintaining manageable system structure through modular layer design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wallpaper system transitions from static to dynamic through virtual camera photographing that captures scene images with depth of field effects. The dynamic wallpaper is generated by processing multiple graphic layers through virtual photographing operations, creating animated transitions during interface switching.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a dynamic wallpaper is used, then user engagement improves, but the range of selectable wallpapers is limited

Engineering Contradiction:
Improvecustomization rangeVSAvoidwallpaper generation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The virtual camera module serves multiple functions: it photographs scene images, generates depth of field effects, creates dynamic wallpaper animations, and processes transitions between different interfaces. This multi-functionality enables extensive customization without proportionally increasing system complexity.

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

Solution Approach 2:

The system uses virtual camera copying to create scene images from multiple graphic layers. Instead of requiring separate physical photographs for each wallpaper, the virtual camera copies and processes the layered graphic elements to generate dynamic wallpaper effects, reducing the need for extensive pre-produced wallpaper assets.

Inventive Principle:
Principle #26Copying

3Illumination intensity

If multiple graphic layers are processed with virtual camera photographing, then spatial effects and depth of field are achieved, but processing power consumption increases

Engineering Contradiction:
Improvevisual effect qualityVSAvoidprocessing power consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

Scene images are pre-photographed by the virtual camera for each preset interface before actual interface switching occurs. These pre-generated scene images are stored and readily available for quick retrieval during interface transitions, avoiding real-time processing of multiple graphic layers when the interface switches, thus reducing instantaneous processing power consumption.

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If scene images are obtained by virtual camera with different photographing angles, then depth of field variation is achieved, but the processing time increases

Engineering Contradiction:
Improvedepth of field accuracyVSAvoidinterface switching time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

Scene images corresponding to different preset interfaces are photographed in advance by the virtual camera with appropriate depth of field settings. During interface switching, the system directly retrieves and displays the pre-prepared scene images, eliminating the need for real-time photographing and processing, thus maintaining high depth of field accuracy while minimizing interface switching time.

Inventive Principle:
Principle #10Preliminary action
