Innovation Solution
A wireless personal tracking device equipped with an electronic compass, accelerometer, biometric sensor, and thin film micro energy cell battery, which uses a combination of received signal strength indicating (RSSI) and Bluetooth communication to enable real-time directional tracking, secure access, and reduce human error in time logging, featuring an electronic paper display and energy harvesting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID systems lack biometric verification, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system merges RFID technology with biometric authentication (fingerprint, facial recognition, or iris scanning) to create a multi-layered security system that combines the convenience of contactless RFID access with the security of physiological verification, ensuring both ease of operation and high security
2Reliability
If NFC requires close proximity to reader, then security is improved, but real-time tracking capability deteriorates
Solution Approach 1:
The system dynamically adjusts communication modes based on distance - using secure NFC when in close proximity for authentication, and switching to Wi-Fi or cellular communication when at a distance to enable real-time tracking, thus maintaining both security and tracking capability across different operational scenarios
3Device complexity
If RFID cards provide limited data, then device complexity is reduced, but information completeness deteriorates
Solution Approach 1:
The system transitions from two-dimensional RFID card data to multi-dimensional data collection by incorporating sensors for location (GPS), movement (accelerometer), orientation (compass), and biometric information, enabling comprehensive employee activity monitoring while maintaining device portability and ease of use
