Solution Overview

Problem

Users face inconvenience in selecting a favorite picture from server-pushed images as the server lacks knowledge of the user's state, making it difficult to apply these images as wallpapers, and the process of choosing a suitable picture on a webpage is time-consuming.

Innovation Solution

A method and mobile terminal that acquire and analyze a user's facial expression to determine their emotion type, filtering a picture gallery to push a target picture matching the user's emotion type, thereby reducing the time spent on picture selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the server pushes pictures aperiodically without knowing user state, then the server can provide picture content, but the pushed pictures are not likely to match user preferences

Engineering Contradiction:
Improveuser state informationVSAvoidpicture matching accuracy
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The system captures the user's facial expression image, analyzes the emotion type, and uses this feedback to determine which picture to push. This creates a closed-loop system where the server adapts to user state, resolving the contradiction between lacking user information and achieving accurate picture matching.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary emotion recognition and analysis before pushing the picture. By capturing and analyzing the user's facial expression in advance, the system determines the appropriate picture to push, ensuring the picture matches user preferences before delivery.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the user manually chooses a picture from pushed pictures or on a webpage, then the user can select a favorite picture, but the process takes a lot of time

Engineering Contradiction:
Improvepicture selection convenienceVSAvoidpicture selection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically performs picture selection based on user facial expression analysis without requiring manual user intervention. The terminal or server autonomously determines and pushes the appropriate picture, eliminating the time-consuming manual browsing and selection process while maintaining user preference accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses rapid facial expression recognition and emotion analysis technology to quickly determine user state and select appropriate pictures, dramatically accelerating the picture selection process compared to traditional manual methods.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)
