Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used to locate electronic devices, then location accuracy is improved, but device complexity increases and GPS capability is required
Solution Approach 1:
A wireless module with NFC antenna and UWB beacon acts as an intermediary between the electronic device and the location determination system. The module contains the GPS-independent location technology, allowing the main device to remain simple while still achieving accurate location tracking through the intermediary component
2Measurement precision
If traditional locating systems are used for non-electronic items, then location tracking is attempted, but the system reliability is poor and location accuracy is insufficient
Solution Approach 1:
The wireless module with NFC and UWB capabilities provides universal location tracking functionality that works for both electronic devices and non-electronic items. The multi-functional design ensures reliable operation across different application scenarios, from tracking smartphones to locating physical property
3Ease of operation
If location data is transmitted without encryption, then communication simplicity is maintained, but information security deteriorates
Solution Approach 1:
The system automatically performs encryption and anonymization of location data without requiring user intervention. The wireless module and external devices handle security protocols autonomously, maintaining communication simplicity while ensuring information security through self-service security measures
