Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional graphics processing architecture is used with direct display connection, then processing simplicity is maintained, but network transmission efficiency deteriorates due to bandwidth limitations

Engineering Contradiction:

Improveprocessing architecture simplicityVSAvoidnetwork transmission efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The graphics processor is divided into multiple independent modules including encryption module, compression module, post-processing module, and multiplexer/error correction/packetization module. Each module performs a specific function to optimize content for network transmission, allowing selective processing based on bandwidth conditions while maintaining overall system efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically selects and configures processing modules based on real-time bandwidth conditions and quality of service requirements. The graphics processor can adaptively adjust which modules are active, enabling efficient transmission across varying network conditions without requiring a complete architectural redesign.

Inventive Principle:

Principle #15Dynamics

2Productivity

If content is encrypted and compressed for network transmission, then transmission efficiency is improved, but processing complexity increases

Engineering Contradiction:

Improvetransmission efficiencyVSAvoidprocessing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Encryption, compression, post-processing, and error correction are implemented as separate, independent modules within the graphics processor. This segmentation allows each function to be optimized independently and enables selective activation based on transmission requirements, managing complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The graphics processor is designed with multi-functional modules that can handle various processing tasks. The same modular architecture supports different encryption algorithms, compression methods, and error correction techniques, providing universal functionality that reduces overall system complexity despite the variety of processing operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If bandwidth limitations are addressed through compression, then transmission capability is improved, but display quality may deteriorate

Engineering Contradiction:

Improvetransmission capabilityVSAvoiddisplay quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The post-processing module applies quality enhancement techniques selectively to different portions of the content based on importance and bandwidth conditions. Critical visual elements receive higher quality processing while less critical areas use more aggressive compression, maintaining overall display quality while improving transmission capability.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system combines multiple processing techniques including encryption, compression, and post-processing in a composite pipeline. Each technique contributes differently to the final output, with compression reducing size and post-processing restoring quality, creating a composite effect that achieves both transmission efficiency and display quality.

Inventive Principle:

Principle #40Composite materials

4Reliability

If error correction and packetization are added for reliable transmission, then transmission reliability is improved, but processing overhead increases

Engineering Contradiction:

Improvetransmission reliabilityVSAvoidprocessing overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Error correction and packetization functions are merged into a single integrated module within the graphics processor. This combination reduces the overhead of having separate processing stages while maintaining the reliability benefits of both functions working together in a coordinated manner.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The multiplexer/error correction/packetization module performs self-configuration based on transmission conditions, automatically adjusting error correction levels and packetization parameters without requiring external control. This self-service capability reduces processing overhead by eliminating the need for additional control logic and configuration management.

Inventive Principle:

Principle #25Self-service
