Solution Overview

Problem

Existing security tags for retail items lack efficient and accurate tracking mechanisms beyond the store environment, leading to potential theft detection gaps and inefficiencies in inventory management.

Innovation Solution

An electronic tracking device that transitions from Bluetooth proximity detection to GPS tracking when it loses visibility of Bluetooth beacons, utilizing a multi-modal communication approach to ensure continuous and precise location monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Bluetooth proximity detection is used for tracking within the store, then communication reliability is improved, but tracking capability deteriorates when the device moves outside the store environment

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidtracking capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically switches between Bluetooth and GPS tracking modes based on the device's location and connectivity status. When Bluetooth beacons are detected, the device uses Bluetooth for tracking; when beacons are lost (indicating exit from store), it transitions to GPS tracking, making the tracking system adaptive to different environments

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The electronic tracking device incorporates multiple tracking functionalities (Bluetooth proximity detection and GPS satellite-based tracking) within a single system, allowing it to perform effective tracking both inside the store (using Bluetooth) and outside the store (using GPS)

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If GPS tracking is continuously activated, then location monitoring precision is improved, but energy consumption increases

Engineering Contradiction:

Improvelocation monitoring precisionVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The device activates GPS tracking periodically or event-driven rather than continuously. GPS is activated when the device determines it has exited the store (via loss of Bluetooth beacon connectivity) or when specifically triggered, rather than operating continuously, thus reducing overall energy consumption while maintaining necessary monitoring precision

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts its tracking mode based on operational needs. Bluetooth low-power proximity detection is used when available, and GPS high-precision tracking is activated only when necessary (when exiting store or triggered by specific events), optimizing the balance between location precision and energy consumption

Inventive Principle:

Principle #15Dynamics

AI summary

Systems, devices, and methods for monitoring an electronic tracking device are described. In one example method, an electronic tracking device determines that the electronic tracking device is moving. After determining that the electronic tracking device is moving, the electronic tracking device determines that the electronic tracking device is not communicatively connected to one or more wireless networks. In response to determining that the electronic tracking device is not communicatively connected to the one or more wireless networks, the electronic tracking device determines location information of the electronic tracking device and sends the location information.
