Existing smart cards and tracking devices face issues such as bulkiness due to physical connections, poor accuracy, short battery life, and reliance on high-power cellular infrastructure, which limits their effectiveness in secure access and location tracking, especially in indoor or underground environments.
Innovation Solution
A tracking device equipped with a first location tracking circuit for wireless communication with a global positioning satellite network, a second location tracking circuit for wireless communication with a local-area network, a biometric identification circuit, and a processor that determines user authorization and location, using low-power wide-area networks like LoRa for efficient and secure tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical connection between reader device and computing device is used, then data transmission reliability is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical physical connection system with a wireless electromagnetic field-based communication system. The reader device communicates with the computing device through wireless signals, eliminating the need for physical cables or connectors while maintaining data transmission reliability through protocol-level error correction and authentication mechanisms.
Solution Approach 2:
The patent introduces wireless communication protocols and signal processing mechanisms as intermediaries between the reader device and computing device. These intermediaries enable reliable data transmission over wireless channels by managing signal integrity, authentication, and error correction without requiring direct physical contact.
2Speed
If smart card remains in reader device during non-use, then access speed is improved, but security deteriorates
Solution Approach 1:
The patent implements dynamic access control where the reader device automatically authenticates the smart card upon insertion and then securely ejects it after the session ends. The system dynamically adjusts the card's access rights based on authentication results and automatically removes the card from the reader device, preventing unauthorized access while maintaining fast authenticated access during active use.
Solution Approach 2:
The patent employs feedback mechanisms where the reader device continuously monitors the smart card's presence and authentication status. After successful authentication, the system provides feedback to maintain access rights temporarily, then automatically revokes access and ejects the card when the session concludes, ensuring security without requiring manual user intervention.
3Speed
If known tracking devices use high-power cellular infrastructure, then communication range is improved, but battery life and energy efficiency deteriorate
Solution Approach 1:
The patent implements partial action by having the tracking device transmit location information only at specified intervals or when location changes occur, rather than continuously. This reduces energy consumption significantly while maintaining effective tracking functionality. The device uses low-power wireless communication for periodic updates instead of continuous high-power cellular transmission.
Solution Approach 2:
The patent employs periodic transmission of location data instead of continuous communication. The tracking device transmits location information at predetermined time intervals or when location changes exceed a threshold, reducing energy consumption while maintaining tracking effectiveness. This periodic action allows the device to enter low-power states between transmissions, extending battery life.
