Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking systems for physical objects in environments with concrete and steel structures, such as airports and warehouses, face inefficiencies due to radio interference and the ineffectiveness of GPS and RFID tracking, leading to misidentification and increased costs, as they rely on fragile paper tags and barcodes that are prone to damage and loss.
Innovation Solution
A system utilizing beacon tags that broadcast radio signals, combined with image recognition and augmented reality, to locate and verify ownership of objects by correlating location data from user devices with object recognition files, providing real-time tracking and ownership verification through a hybrid use of beacon, RFID, and GPS tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS tracking is used to locate physical objects, then location tracking is enabled, but it becomes ineffective inside concrete and steel buildings such as airports
Solution Approach 1:
The system divides the tracking function into multiple components: beacon tags for indoor location, RFID tags for identification, and GPS for outdoor tracking. Each component operates independently in its optimal environment, with the beacon network segmented into multiple access points throughout the building to overcome signal blockage by concrete and steel structures.
Solution Approach 2:
Beacon tags and access points serve as intermediaries between the tracking system and objects inside buildings. These intermediaries relay location information through local wireless communication, bypassing the need for direct GPS satellite signals that are blocked by concrete and steel structures.
2Reliability
If RFID tracking is used to locate physical objects, then identification is enabled, but it becomes ineffective due to radio interference from steel structures
Solution Approach 1:
The system merges RFID technology with beacon-based tracking and augmented reality verification. RFID tags provide quick identification while beacon tags provide continuous location tracking, and augmented reality provides visual verification. This combination compensates for RFID's weakness in steel structure environments by adding redundant identification methods.
Solution Approach 2:
The beacon tags serve multiple functions: they provide location tracking, enable augmented reality verification, and act as identification markers. This multi-functionality replaces the单一的 RFID identification system with a more robust multi-functional system that works reliably in steel structure environments.
3Reliability
If paper tags and barcodes are used for object identification, then ownership verification is enabled, but they are fragile and prone to damage and loss
Solution Approach 1:
The system creates digital copies of identification information stored in databases associated with beacon and RFID tags. Instead of relying on physical paper tags that can be damaged, the verification information is copied to electronic storage and accessed wirelessly through user devices, providing durable and repeatable verification.
Solution Approach 2:
The system replaces the mechanical paper tag and barcode system with electronic beacon tags, RFID tags, and augmented reality displays. This substitution eliminates the physical fragility of paper while maintaining the identification and verification functions through wireless communication and digital displays.
4Reliability
If blueprinting an entire building is done to enable RFID tracking, then tracking coverage is improved, but it increases expense and time requirements
Solution Approach 1:
The beacon tags and user devices perform self-configuration and automatic location determination without requiring pre-planned blueprints. The system automatically maps the environment through wireless signal triangulation and device-based positioning, eliminating the need for time-consuming and expensive manual blueprinting while achieving comprehensive coverage.

Data Source
AI summary
A system is provided which utilizes multiple combinations of object location technology to locate objects and direct users to them, and which provides reliable owner recognition and ownership verification with the use of displayed augmented reality with a predefined image of the object and/or the user. Further, the system utilizes augmented reality fingerprint markers. When the augmented reality fingerprint marker is positioned on an object and scanned with a smart device, information relating to the object is superimposed on the object displayed on the smart device.
