Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified communication and control network is used in intelligent manufacturing, then system integration is simplified, but calculation pressure concentrates in the transmission control center causing data traffic jams
Solution Approach 1:
The patent divides the unified communication and control network into multiple independent sensor network platforms, each handling specific data processing tasks. This segmentation distributes calculation pressure from the centralized transmission control center to multiple distributed nodes, preventing data traffic jams while maintaining system integration through standardized interfaces and protocols.
2Ease of operation
If calculation pressure is concentrated in the transmission control center, then centralized control is achieved, but load increases causing system bottlenecks
Solution Approach 1:
The patent segments computational functions by introducing edge computing capabilities at the sensor network platform level. Routine data processing and filtering are performed locally at distributed sensor nodes, while the transmission control center focuses on high-level decision-making and coordination, thus maintaining centralized control authority while distributing computational load.
Solution Approach 2:
The patent introduces sensor network platforms as intermediary layers between production devices and the transmission control center. These intermediaries perform preliminary data processing, aggregation, and filtering, reducing the volume and complexity of data transmitted to the control center, thereby lowering its computational load while preserving centralized oversight.
3Productivity
If independent sensor network platforms are created, then calculation pressure is distributed, but system architecture becomes more complex
Solution Approach 1:
The patent designs sensor network platforms with universal, multi-functional capabilities that can handle various data processing tasks across different production scenarios. By creating standardized, reusable platform modules with consistent interfaces and protocols, the system achieves distributed processing efficiency without proportionally increasing architectural complexity, as the same platform architecture can be replicated across multiple nodes.
