Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If preset pictures are displayed on mobile terminals when the screen is off, then the display function is simple and easy to implement, but the display content is monotonous and unvarying

Engineering Contradiction:
Improvedisplay implementation simplicityVSAvoiddisplay content variety
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transforms static preset pictures into dynamic generated pictures by introducing random factors and environmental parameters. The display content dynamically changes based on time, location, device orientation, and other environmental factors, making the screen-off display adaptable and varied while maintaining simple implementation through algorithmic generation rather than manual picture selection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters used for picture generation by incorporating environmental parameters such as time, location, temperature, and device orientation. Instead of using fixed preset pictures, the system generates pictures with varying parameters based on real-time environmental data, achieving display content variety while keeping the implementation straightforward through parameter-driven generation.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If generated pictures with environmental adaptations are displayed, then display content variety is improved, but processing complexity increases

Engineering Contradiction:
Improvedisplay content varietyVSAvoidpicture processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the picture generation process into distinct modules: environmental parameter acquisition, random factor generation, picture element generation, and composition. Each module performs a specific function, making the overall complex process manageable and implementable through standardized, independent components that can be executed sequentially or in parallel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs self-service by automatically acquiring environmental parameters, generating random factors, and creating display pictures without requiring manual intervention. The device uses its own sensors and processing capabilities to generate adaptive display content, reducing the need for external input or complex user configuration while achieving varied and adaptive display results.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If multiple processing steps including contour extraction and pixel translation are applied, then picture generation quality is improved, but processing time increases

Engineering Contradiction:
Improvepicture generation qualityVSAvoidpicture processing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-defining the structure and characteristics of pictures to be generated, including contour patterns, element types, and composition rules. By establishing these templates and rules in advance, the system can quickly generate high-quality pictures during screen-off periods without requiring extensive real-time processing, thus maintaining both quality and efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by selectively processing only the essential elements needed for picture generation, such as key contour features and major composition components, rather than processing every detail exhaustively. This approach achieves sufficient picture generation quality while reducing processing time by focusing computational resources on the most impactful elements.

Inventive Principle:
Principle #16Partial or excessive action
