Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If device-to-device control strategy is used, then the system structure is simple, but the collaborative interaction between sensors and electrical apparatuses is limited
Solution Approach 1:
The patent introduces a fusion node as an intermediary component between sensing nodes and electrical apparatuses. This fusion node receives data from multiple sensing nodes, performs data fusion to generate spatial state features, and then controls the electrical apparatuses based on these features. This intermediary structure enables enhanced collaborative interaction without requiring direct complex connections between all sensors and all apparatuses.
2Extent of automation
If conventional sensor control is used, then the control logic is simple, but the intelligent level of the building system is insufficient
Solution Approach 1:
The system performs preliminary data fusion and spatial state feature generation before controlling electrical apparatuses. The fusion node pre-processes data from multiple sensing nodes to create comprehensive spatial state features that characterize the building environment. This preliminary action enables more intelligent and informed control decisions while maintaining relatively simple control logic at the execution level.
Solution Approach 2:
The fusion node serves as an intermediary that enhances the intelligent level by performing sophisticated data fusion and spatial analysis. This intermediary layer handles the complexity of processing multiple sensor inputs and generating meaningful spatial state features, allowing the control system to operate at a higher intelligent level without overwhelming the control logic with raw data complexity.
3Measurement precision
If spatial state feature generation is implemented, then the control precision is improved, but the data processing complexity increases
Solution Approach 1:
The system segments the data processing function into distinct components: sensing nodes collect raw data, the fusion node performs data fusion and generates spatial state features, and the control system executes control actions based on these features. This segmentation allows control precision to be improved through comprehensive spatial state features while distributing the data processing complexity across multiple specialized components rather than concentrating it all in one system.
