Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data from smart meters are collected and processed by a central control unit, then energy balance can be monitored, but the calculation time becomes excessively long for real-time balancing requirements
Solution Approach 1:
The patent divides the central control unit into multiple logical control nodes arranged in a tree structure with hierarchical levels. Each logical control node processes data from specific connection points independently, segmenting the monolithic processing task into parallel sub-tasks that can be executed simultaneously, thereby reducing overall calculation time while maintaining comprehensive energy balance monitoring
Solution Approach 2:
The patent introduces a hierarchical dimensional structure with multiple levels of logical control nodes. Data processing occurs across different hierarchical dimensions, where lower-level nodes handle local connection points and higher-level nodes aggregate results, adding a spatial-distributive dimension to the processing architecture that enables parallel computation and reduces time complexity
2Adaptability or versatility
If more connection points are connected to the distribution network, then energy management coverage increases, but the complexity of calculating system energy balance increases
Solution Approach 1:
The patent segments the network into multiple zones, each managed by logical control nodes at different hierarchical levels. Each logical control node is responsible for a specific subset of connection points, dividing the complex system-wide calculation into simpler local calculations that can be performed independently and then aggregated, reducing overall computational complexity while maintaining comprehensive coverage
Solution Approach 2:
The patent adds a hierarchical dimension to the network architecture, organizing logical control nodes into multiple levels. This hierarchical dimension allows the system to scale to accommodate more connection points by distributing management across multiple hierarchical layers, transforming a single-layer complex problem into a multi-layer structured problem that is more manageable and scalable
3Productivity
If energy balance calculation is performed in real-time with 1 second intervals, then energy overflow can be minimized, but normal computing power is insufficient to achieve this
Solution Approach 1:
The patent segments the computing task across multiple logical control nodes that operate in parallel. By dividing the overall energy balance calculation into concurrent local calculations at different hierarchical levels, the system achieves real-time processing capability (1 second intervals) by distributing the computational load, effectively multiplying the available computing power through parallelization
Solution Approach 2:
The patent introduces parallel processing as a new dimension of computation by implementing multiple logical control nodes that operate simultaneously. This parallel computational dimension allows the system to process energy balance data from multiple connection points concurrently, achieving real-time calculation speeds that exceed the capabilities of sequential processing with normal computing power
