Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking systems lack the ability to seamlessly switch between short-range and long-range location services, and they do not integrate wide-ranging sensors, multiple communication interfaces, or hierarchical aggregation management.
Innovation Solution
An item tracking system that employs flexible electronic tracking labels with integrated sensors, multiple communication interfaces (including Bluetooth and cellular networks), and a server-based database to manage tracking histories. The system automatically switches between short-range and long-range location services based on communication availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tracking label uses long-range communication interfaces (cellular networks) for continuous location tracking, then the tracking coverage and reliability are improved, but the power consumption increases significantly
Solution Approach 1:
The tracking label dynamically switches between long-range and short-range communication modes based on the availability of short-range devices. When a short-range device is detected via Bluetooth, the system transitions to use short-range Wi-Fi communication for location tracking, thereby reducing power consumption while maintaining tracking reliability.
Solution Approach 2:
The tracking label autonomously determines the availability of short-range communication devices and self-manages the switch between communication interfaces without external intervention. The controller automatically detects nearby devices and adjusts the communication mode to optimize energy usage while ensuring continuous tracking functionality.
2Use of energy by moving object
If the tracking label uses only short-range communication (Bluetooth) for location tracking, then the power consumption is reduced, but the tracking coverage and reliability deteriorate when outside the range of short-range devices
Solution Approach 1:
The tracking label incorporates multiple communication interfaces (Bluetooth, Wi-Fi, and cellular) within a single device, enabling it to function across different communication ranges. The system universally supports both short-range and long-range communication modes, allowing it to adapt to various environmental conditions and maintain tracking reliability regardless of the presence of short-range devices.
3Adaptability or versatility
If the tracking label integrates multiple communication interfaces and sensors, then the functionality and tracking capability are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple communication interfaces (Bluetooth, Wi-Fi, cellular) and various sensors (GPS, accelerometer, temperature, humidity) into a single integrated tracking label device. This merging of functions allows the label to perform diverse tracking and monitoring tasks while managing the complexity through unified hardware and software architecture.
Solution Approach 2:
The controller acts as an intermediary that manages the multiple communication interfaces and sensors. It coordinates between different hardware components, processes data from various sources, and makes intelligent decisions about which communication mode to use, thereby simplifying the overall system operation despite the presence of multiple complex components.

AI summary
An item tracking system that uses smart tracking labels to track an item's position, and that switches between short-range tracking within a local area using short-range interfaces like Bluetooth and long-range tracking within a global or regional area using long-range interfaces like GPS. Long-range communication interfaces may be disabled when the tracking label comes within range of a short-range network such as a Bluetooth network within a warehouse. Switching to short-range services when they are available may significantly reduce the total power requirement for a tracking label. In an illustrative embodiment a tracking label may periodically broadcast an advertising message over Bluetooth; when a Bluetooth gateway in a warehouse or other local area responds to this message, the label disables long-range interfaces and switches position tracking to use short-range services. When the label loses communication with a short-range network, it re-enables the long-range interfaces.
