Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user manually selects and sets wallpaper through settings menu, then wallpaper can be changed, but the process is complex and time-consuming

Engineering Contradiction:
Improvewallpaper setting operationVSAvoidtime for wallpaper setting
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically captures screenshots, selects appropriate images, and applies them as wallpaper without requiring user intervention. The electronic device performs the entire wallpaper setting process autonomously by detecting user actions and automatically configuring the display.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-captures screenshots at predetermined time points and pre-processes them for wallpaper use. By preparing potential wallpaper images in advance during normal operation, the system eliminates the need for manual selection and setup when wallpaper change is desired.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If wallpaper is changed frequently to reflect user mood, then personalization is improved, but battery consumption increases

Engineering Contradiction:
Improvewallpaper personalizationVSAvoidbattery consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system changes wallpaper at predetermined time intervals or specific triggering events rather than continuously or frequently. This periodic approach allows personalization while controlling energy consumption by limiting the frequency of wallpaper updates.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses existing screenshot images with different resolution parameters for different display scenarios. By reusing captured images at different quality levels rather than constantly capturing new high-resolution images, the system achieves personalization while reducing the energy cost of image processing and display updates.

Inventive Principle:
Principle #35Parameter changes

AI summary

This application provides a wallpaper setting method and an electronic device, and is relates to the field of terminal technologies. In the wallpaper setting method, a second interface displayed by the electronic device includes a first wallpaper, a second wallpaper and a first control. The first wallpaper and the second wallpaper are different wallpapers generated based on a same image. The electronic device sets the first wallpaper as a wallpaper of a first display and sets the second wallpaper as a wallpaper of a second display in response to a second operation on the first control on the second interface. That is, a user can set the first wallpaper of the first display and the second wallpaper of the second display through one trigger, which is convenient and quick to operate and has high efficiency.
