VSEngineering Contradiction Analysis

1Productivity

If graph code is used to perform various operations in parallel computing platforms, then productivity is improved, but device complexity increases due to the complexity of graph code management

Engineering Contradiction:

Improveexecution efficiency of graph operationsVSAvoidcomplexity of graph code management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system consisting of capture interfaces and graph management APIs that mediate between the programmer and the complex graph code execution engine. This intermediary layer provides simplified interfaces for creating, capturing, and managing graph code, thereby maintaining high execution efficiency while reducing the perceived complexity for users.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the graph code management process into distinct functional components: graph creation, stream capture, dependency management, and execution control. By dividing the complex management task into manageable segments with dedicated interfaces, the system maintains productivity while reducing overall management complexity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If stream capture is used to manage graph code operations, then ease of operation is improved, but device complexity increases due to additional capture and dependency management mechanisms

Engineering Contradiction:

Improveease of graph code managementVSAvoidcomplexity of capture and dependency mechanisms

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The stream capture mechanism automatically manages graph code operations without requiring manual intervention for complex dependency tracking. The system self-services by automatically capturing stream operations, building dependency graphs, and managing execution states, thereby improving ease of operation while the internal complexity is handled autonomously by the system.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements feedback mechanisms where the stream capture system continuously monitors operation states, updates dependency relationships, and adjusts execution plans based on captured information. This feedback loop enables automatic adaptation to changing conditions, simplifying user operation while managing internal complexity through continuous state awareness.

Inventive Principle:

Principle #23Feedback
