Solution Overview

Problem

Existing asset tracking systems face challenges in confined spaces due to reliance on GNSS, which is inadequate indoors, and require infrastructure like VHF towers, making them vulnerable to theft and costly.

Innovation Solution

A system utilizing low-energy Bluetooth Low Energy (BLE) connectivity between primary and auxiliary tracking devices, with pairing initiated by the primary device, enabling secure communication and transitioning to alarm mode if primary device is not detected, using GSM for location updates when motion is detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If VHF towers and infrastructure are used for asset tracking, then tracking reliability is improved, but device complexity and infrastructure requirements increase

Engineering Contradiction:

Improvetracking reliabilityVSAvoidinfrastructure requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the tracking functionality from infrastructure-dependent systems (VHF towers, GNSS) and implements it using standalone BLE devices that operate independently without requiring external infrastructure, thereby reducing device complexity while maintaining tracking capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces BLE technology as an intermediary communication method between tracking devices and smartphones, replacing the need for VHF tower infrastructure and enabling reliable indoor tracking through peer-to-peer communication

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If continuous transmission is used for asset tracking, then tracking reliability is improved, but energy consumption increases

Engineering Contradiction:

Improvetracking reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic transmission where auxiliary devices send low-energy signals at intervals rather than continuously, and primary devices transmit location information only when motion is detected or at scheduled intervals, significantly reducing energy consumption while maintaining tracking reliability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent employs dynamic transmission strategies where the primary device adjusts its transmission behavior based on motion detection - transmitting location information when movement is detected and entering low-power mode when stationary, optimizing the balance between reliability and energy consumption

Inventive Principle:

Principle #15Dynamics

3Reliability

If constant communication is used for asset tracking, then tracking reliability is improved, but detectability and theft risk increase

Engineering Contradiction:

Improvetracking reliabilityVSAvoidtheft risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses periodic communication where auxiliary devices transmit low-energy signals at intervals rather than continuously, making the tracking system harder to detect by thieves while maintaining reliable tracking functionality through periodic location updates

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent implements different communication behaviors for different devices - auxiliary devices use low-energy periodic signals for stealth, while the primary device communicates location information selectively based on motion detection, creating a layered approach that balances reliability and stealth

Inventive Principle:

Principle #3Local quality

4Reliability

If GNSS tracking is used for asset tracking, then tracking reliability in open areas is improved, but applicability in confined spaces deteriorates

Engineering Contradiction:

Improvetracking reliability in open areasVSAvoidindoor tracking capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal tracking system that works both indoors and outdoors by combining BLE technology (for indoor confined spaces) with optional GNSS integration (for outdoor open areas), allowing the same system to adapt to different environments and eliminating the limitation of GNSS-only solutions

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Method and system for object tracking comprises transmission of tracking signal of primary and auxiliary tracking devices and exchange of information between the primary and the auxiliary tracking devices via low-energy Bluetooth connectivity (BLE), in the 2.4 GHz frequency band. Auxiliary tracking device connects automatically to primary tracking device upon activation of auxiliary tracking device. After successful pairing with primary tracking device auxiliary tracking device activates GATT service with the following characteristics: status of the internal power supply, product uptime, counter of received periodic BLE packets, counter of undetected periodic BLE packets, counter of the number of alarms, GSM module uptime. After pairing auxiliary tracking device communicates with primary tracking device by sending periodic BLE information packets and waits for feedback, and if, during the feedback search, auxiliary tracking device does not detect a BLE packet transmitted by primary tracking device, the auxiliary tracking device switches to the alarm mode.
