Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID tags are used for wireless identification and tracking, then automatic identification and data transmission are improved, but communication range is limited to close proximity only
Solution Approach 1:
The patent combines RFID technology with Bluetooth Low Energy (BLE) in a hybrid tag system. The RFID component provides close-range automatic identification while the BLE component extends communication range to meters, allowing the system to benefit from both technologies' strengths simultaneously.
Solution Approach 2:
The tag is designed to perform multiple functions: RFID for close-proximity identification, BLE for extended-range communication and location tracking, and optional GPS for global positioning. This multi-functional approach allows a single device to serve multiple purposes across different communication ranges.
2Measurement precision
If Smartphones with GPS are used for location tracking, then location accuracy is improved, but device security and reliability for tracking external assets deteriorates
Solution Approach 1:
The patent introduces a dedicated tracking tag as an intermediary device attached to the asset being tracked. This tag contains its own GPS receiver and communication modules, serving as a reliable intermediary that directly reports asset location without depending on the target device's (e.g., smartphone) security or availability.
Solution Approach 2:
The tracking tag is a self-contained device with integrated GPS, RFID, and BLE components that autonomously performs location tracking and data transmission. It does not require the target asset's device to be secure, powered on, or cooperative, making the tracking system reliable and independent.
3Use of energy by moving object
If Bluetooth Low Energy is used for low power wireless communication, then energy consumption is reduced, but data transmission capability and range are limited
Solution Approach 1:
The system merges BLE with RFID and optional GPS technologies. BLE handles low-power periodic location updates and collects data from GPS, while RFID provides close-range identification. This combination allows the system to maintain low power consumption while still achieving comprehensive data collection and extended communication capability when needed.

AI summary
Methods and systems for establishing communication between multiple GRL (Global Resource Locator) devices in proximity to one another. The method includes detecting the presence of other GRL devices using a low power wireless transmission protocol, transmitting universally unique identifiers (UUIDs), and establishing communication links to form a collective. The system stores data received from the GRL devices, determines if any devices have been added or are missing, and transmits the stored data to a receiving device. The method further includes generating and storing location and sensor measurement data, encrypting transmitted data, and authenticating UUIDs. The system ensures accurate data transmission through clock synchronization and generates metrics for quality of service, power consumption, signal strength, and proximity. This invention enhances the tracking, monitoring, and management of assets equipped with GRL devices.
