Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual parameter categorization is used for machine learning training, then the machine learning model can be trained, but the training time becomes very long
Solution Approach 1:
The LwM2M server automatically categorizes sensor parameters by adding categorization information to resource data, enabling the machine learning system to self-organize training data without human intervention. This self-service approach resolves the contradiction by automating the categorization process, maintaining accuracy while eliminating time-consuming manual effort.
Solution Approach 2:
The patent applies preliminary action by pre-categorizing parameters during data collection and storage in the LwM2M server. By organizing data with categorization metadata before training begins, the system prepares everything in advance, eliminating the need for time-consuming manual categorization during the training phase while ensuring accuracy is maintained.
2Reliability
If traditional simulation platforms are used to train machine learning models, then the models can be trained, but the system scalability is poor
Solution Approach 1:
The patent implements universality by designing an LwM2M-based solution that can handle multiple types of sensor data from various sources through a standardized interface. The server universally processes different parameter types with consistent categorization, enabling the system to scale across diverse IoT deployments while maintaining reliable training through standardized data organization.
Solution Approach 2:
The patent applies segmentation by dividing the training system into modular components: data collection, categorization, storage, and training. This modular architecture allows each component to be independently optimized and scaled, improving system versatility while maintaining reliability through standardized interfaces between segments.
3Manufacturing precision
If extensive human design and configuration is applied to organize sensor data, then the machine learning model can be properly trained, but the process becomes time-consuming
Solution Approach 1:
The LwM2M server performs automatic categorization of sensor parameters by examining resource data and adding appropriate categorization metadata without human intervention. This self-service mechanism maintains high data organization quality through systematic categorization while dramatically improving training efficiency by eliminating manual configuration steps.
Solution Approach 2:
The patent introduces an intermediary categorization layer between raw sensor data and the machine learning model. The LwM2M server acts as a mediator that automatically organizes data with categorization metadata, ensuring high organization quality while improving productivity by removing the need for human designers to manually configure data structures.
