Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sensor data is stored and transmitted in its original form, then data completeness is maintained, but storage capacity and communication bandwidth are quickly exhausted
Solution Approach 1:
The patent extracts only the essential feature amounts from the complete sensor data set. The control unit identifies and extracts key characteristics (feature amounts) that represent the most important information from the raw sensor data, transmitting only these extracted features rather than the entire data set, thereby reducing data volume while maintaining information quality
Solution Approach 2:
The patent transforms the sensor data from its original form into a different parameter representation. By converting raw sensor data into feature amount data through feature amount generation processing, the system changes the parameter form of the data, reducing its volume while preserving the essential information needed for analysis
2Quantity of substance
If feature amount generation processing is performed on sensor data, then data volume is reduced for efficient storage and transmission, but processing time and computational resources are consumed
Solution Approach 1:
The control unit performs feature amount generation processing in advance, before data transmission is needed. By pre-processing the sensor data to extract feature amounts and storing them ready for transmission, the system prepares the reduced data set beforehand, so that when transmission is required, the data is already optimized and ready to go, reducing the time pressure during actual transmission operations
