Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If memory-mapped interconnect architecture is used for data transfer between system components, then data sharing capability is improved, but processing efficiency deteriorates due to memory round trips

Engineering Contradiction:

Improvedata sharing capabilityVSAvoidprocessing efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent introduces a stream processor as an intermediary component between system components, enabling direct data streaming and processing without requiring memory round trips. The stream processor receives data streams from one component and passes processed data to another component, acting as a mediator that eliminates the inefficiency of memory-based data transfer while maintaining data sharing capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If memory-mapped interconnect architecture is used for data transfer, then system integration is improved, but power consumption increases due to asynchronous memory operations

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The stream processor serves as an intermediary that enables synchronous data streaming between components, eliminating the need for asynchronous memory operations. By directly passing data through the stream processor, the system reduces power consumption associated with memory access while maintaining system integration and data sharing capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If memory round trips are used for data retrieval, then data access flexibility is improved, but latency increases

Engineering Contradiction:

Improvedata access flexibilityVSAvoidlatency

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent implements continuous data streaming through the stream processor, where data flows continuously from source to destination without interruption. This continuous action eliminates the start-stop nature of memory round trips, reducing latency while maintaining data access flexibility. The stream processor maintains data flow continuity by directly passing data between components in real-time.
