Solution Overview

Problem

Current methods for preventing theft in retail settings, such as video surveillance and anti-theft badges, are inadequate due to limitations in monitoring large areas and the inability to distinguish between items with the same barcode, leading to inventory discrepancies and fraudulent transactions.

Innovation Solution

A device with a locking mechanism and an optically readable code distinct from the standard barcode, which can be read by electronic devices to securely identify and track items, preventing substitution and ensuring accurate pricing and inventory management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If standard barcodes (EAN, EPC) are used for item identification, then items can be tracked through the supply chain, but items with the same barcode cannot be distinguished from each other

Engineering Contradiction:
Improveitem identification capabilityVSAvoiditem distinction accuracy
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The identification system is segmented into two distinct code types: standard barcodes for supply chain tracking and unique optically readable codes for individual item identification. This segmentation allows each code type to serve its specific purpose without interference, resolving the contradiction between bulk tracking and individual distinction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A unique optically readable code acts as an intermediary between the standard barcode and the point-of-sale system. This intermediary code provides the additional layer of individual item identification needed to distinguish between multiple items sharing the same standard barcode.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If price tags are substituted with lower-priced item tags, then fraudulent transactions occur, but detection is difficult with current systems

Engineering Contradiction:
Improvetransaction speedVSAvoidtransaction accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback by reading the unique optically readable code at the point of sale and verifying it against the scanned barcode in the computer system. This feedback mechanism detects discrepancies between the intended item and the actual item, preventing fraudulent transactions while maintaining transaction speed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The manual verification process is replaced with an automated optical code reading system. The electronic reading and verification of unique codes provides rapid, accurate detection of price tag substitution fraud without slowing down the transaction process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If video surveillance is used to monitor store areas, then theft detection is possible, but blind spots and limited monitoring capacity reduce effectiveness

Engineering Contradiction:
Improvetheft detection capabilityVSAvoidmonitored area coverage
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

Each item carries its own identification code that actively participates in the security system. The unique optically readable code on each item enables automatic identification and tracking without requiring external surveillance, effectively making each item self-monitoring and eliminating blind spots.

Inventive Principle:
Principle #25Self-service

4Reliability

If anti-theft badges are used on items, then theft prevention is achieved, but internal employees can remove or deactivate them

Engineering Contradiction:
Improvetheft prevention effectivenessVSAvoidbadge security against internal threats
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The unique optically readable code is merged with the item's pricing and identification system. This integration means the security feature is inseparable from the item's commercial identification, making it impossible to remove or deactivate without affecting the item's trackability and pricing.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A device for protecting a commercial article which is a physical object (10, 32), that may or may not be packaged, against theft. The device (12, 42) includes: at least one active or passive member that is capable of emitting electromagnetic waves out from the device or receiving electromagnetic waves from outside the device; elements for attaching and locking the device to the physical object or to the packaging of same in a locked position such that a user cannot separate the device from the physical object without an external tool, the locking elements including a locking mechanism; and at least one optically readable code (24) uniquely identifying the physical object to which the device is intended to be attached and which is separate from a commercial article code (EAN, EPC, etc.) assigned to the physical object, as a commercial article.
