Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data collection methods are used in chaotic environments, then data can be collected, but connectivity outages and transmission errors increase, reducing reliability
Solution Approach 1:
The system performs preliminary data collection and storage at the point of identification before transmission becomes problematic. The wearable device continuously monitors and stores data locally, ensuring data is ready for immediate transmission when connectivity is restored, thereby preventing data loss during connectivity outages.
Solution Approach 2:
The patent introduces an intermediary storage layer (local memory in the wearable device and intermediate servers) between the data collection point and the final cloud storage. This intermediary layer acts as a buffer during connectivity outages, allowing data to be stored locally and later synchronized when connectivity is restored, thereby maintaining reliability.
2Measurement precision
If rapid data collection is implemented at the point of identification, then data accuracy improves, but the complexity of the data collection system increases
Solution Approach 1:
The wearable device is designed as a multi-functional platform that combines sensors for monitoring, NFC for identification, Bluetooth for wireless communication, and local storage capabilities. By consolidating these functions into a single device, the system achieves rapid and accurate data collection without proportionally increasing overall system complexity.
Solution Approach 2:
The wearable device autonomously performs data collection, processing, and preliminary storage without requiring constant external intervention. The device self-manages its sensors, communication modules, and storage, reducing the complexity of centralized control systems while maintaining high data accuracy through continuous local operation.
3Duration of action of moving object
If data is collected in disconnected environments, then operational continuity is maintained, but data transmission and processing capabilities are limited
Solution Approach 1:
The system performs all necessary data collection, processing, and storage operations locally while disconnected from central systems. The wearable device pre-processes data, manages storage, and prepares transmission packets in advance, so that when connectivity is restored, data can be immediately transmitted without interrupting operational continuity.
Solution Approach 2:
The patent ensures continuous operational action by maintaining local data collection and processing capabilities independent of external connectivity. The wearable device continuously monitors and stores data even when disconnected, and automatically synchronizes with central systems when connectivity is restored, thereby maintaining both operational continuity and eventual data processing capability.
