Solution Overview

Problem

Existing ink stain antitheft tags are unreliable, costly, and lack efficient inventory management capabilities, as they often require complete replacement for technological upgrades and fail to provide a unified solution for theft deterrence and inventory tracking.

Innovation Solution

Incorporating an RFID pin with a low-cost RFID circuit into the securing pin of existing antitheft tags, allowing them to function as both theft prevention devices and inventory management tools without the need for full replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional ink stain antitheft tags are used, then theft deterrence is provided, but inventory management capability is lacking

Engineering Contradiction:

Improveinventory management capabilityVSAvoidtheft deterrence reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines an RFID circuit with the traditional ink stain antitheft tag mechanism into a single integrated device. The RFID circuit is embedded within the tag housing alongside the ink ampules and securing mechanism, allowing the device to simultaneously provide theft deterrence through ink discharge and inventory management through RFID communication.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The antitheft tag is designed to perform multiple functions: traditional theft deterrence via ink discharge and modern inventory management via RFID communication. This multi-functional design allows a single device to replace both the conventional antitheft tag and a separate RFID tracking system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If complete replacement of existing antitheft tags is done for technological upgrades, then new functionality is achieved, but cost increases

Engineering Contradiction:

Improvetechnological functionalityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent segments the antitheft tag into replaceable modules, particularly the RFID circuit component that can be independently installed or upgraded. This modular approach allows merchants to upgrade only the electronic components rather than replacing entire tag assemblies, reducing upgrade costs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary RFID circuit module that can be integrated into existing tag housings. This intermediary component serves as a bridge between traditional mechanical antitheft tags and modern RFID systems, allowing gradual technological transition without complete system replacement.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If RFID circuit is integrated into antitheft tag, then inventory management capability is improved, but device complexity increases

Engineering Contradiction:

Improveinventory management efficiencyVSAvoidtag structure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The RFID circuit is nested within the existing tag housing structure, utilizing the same spatial envelope as the traditional mechanical components. The RFID circuit board and antenna are integrated into the tag body alongside the ink ampules and securing mechanism, avoiding external additions that would increase overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The invention provides an RFID circuit for use with new or pre-existing antitheft tags. An RFID pin replaces the current pin on antitheft tags that retailers already own. The RFID circuit is incorporated into or secured to, the pin structure. By replacing the current pin used on antitheft tags with a low cost RFID pin, existing antitheft tags can be inexpensively upgraded to antitheft tags that are also capable of use as inventory management and/or enhanced theft control devices.
