Solution Overview

Problem

Existing electronic devices face limitations in providing personalized on-screen display patterns without occupying excessive memory, particularly in screen-off or locked states, as they rely on fixed, downloaded patterns.

Innovation Solution

A method and apparatus for generating graffiti patterns based on user-input text information, utilizing attribute information such as overlapping areas, tilt angles, and edge information to combine graffiti letter images, thereby creating personalized patterns without the need for large storage occupancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large quantity of pictures are downloaded and stored locally, then the displayed pattern type is enriched, but a very large amount of memory is occupied

Engineering Contradiction:
Improvedisplayed pattern typeVSAvoidmemory occupation
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent uses vector graphics (SVG) to represent patterns instead of storing actual image files. Vector graphics store mathematical descriptions of shapes, lines, and curves, which can be rendered at any resolution without quality loss. This allows the system to generate diverse pattern variations from a single set of vector definitions, dramatically reducing storage requirements while maintaining pattern diversity and quality.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs parameterized vector graphics where patterns are defined by adjustable parameters such as line width, color, spacing, and geometric properties. By modifying these parameters, the system can generate multiple pattern variations from the same base vector definition, enabling rich pattern diversity without storing multiple copies of each pattern image.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If fixed patterns stored locally are used, then the implementation is simple, but the personalized requirement of the user cannot be met

Engineering Contradiction:
Improveimplementation simplicityVSAvoidpersonalized requirement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transforms static, fixed patterns into dynamic, user-customizable patterns through vector graphics technology. Users can modify pattern parameters such as text content, font style, line thickness, and color in real-time, and the system dynamically renders the updated patterns. This dynamic approach maintains implementation simplicity while enabling extensive personalization options.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent provides users with direct control over pattern customization through an intuitive interface where users can edit text, adjust parameters, and preview changes immediately. The system processes user inputs and generates personalized patterns on-demand without requiring complex pre-processing or manual intervention, enabling users to serve their own personalization needs efficiently.

Inventive Principle:
Principle #25Self-service
