Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security labels face issues with adhesion on certain surfaces, especially when exposed to heat or solvents, and lack multi-functional capabilities such as counterfeit-evidence, tamper-evidence, and refill-evidence. Additionally, single-layer security labels can be easily breached.

Innovation Solution

A tamper-evident security system featuring a dual-layer security label with a first layer containing a machine-scannable code associated with initial information and a second layer with a code that remains hidden until irreversible disengagement, providing enhanced authentication and tamper-evidence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If self-adhesive security labels are used, then ease of application is improved, but adhesion strength deteriorates on certain surfaces when exposed to heat or solvent

Engineering Contradiction:

Improveease of applicationVSAvoidadhesion strength

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The security label is divided into multiple layers (first layer with first code, second layer with second code). This segmentation allows each layer to serve specific functions while collectively providing strong adhesion and tamper evidence. The multi-layer structure enables the label to maintain reliability on surfaces exposed to heat or solvent while preserving ease of application.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The security label employs composite material structure with multiple layers having different properties. The combination of materials in different layers provides both strong adhesion characteristics for reliable attachment to various surfaces and ease of application through self-adhesive properties, resolving the contradiction between these two features.

Inventive Principle:

Principle #40Composite materials

2Device complexity

If single layer security label is used, then device complexity is reduced, but security against breaching deteriorates

Engineering Contradiction:

Improvelabel structure complexityVSAvoidsecurity against breaching

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The security label employs nested structure where one layer is disposed over another layer. The first layer is disposed over the second layer in a way that at least a portion of the second code on the second layer is covered by the first layer. This nesting provides enhanced security while maintaining manageable complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of manufacture

If security label is designed for single task, then manufacturing simplicity is improved, but authentication versatility deteriorates

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidauthentication capabilities

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The security label is designed with multi-functionality to perform various authentication tasks including counterfeit-evidence, tamper-evidence, and refill-evidence. The first layer with first code and second layer with second code enable different authentication modes, allowing a single label to address multiple security requirements without significantly complicating manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The security label utilizes a multi-layer dimensional structure where the first layer is disposed over the second layer. This dimensional approach enables the label to provide multiple authentication functions (counterfeit-evidence, tamper-evidence, refill-evidence) simultaneously, enhancing versatility while maintaining manufacturing feasibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If heat is applied to enable easy peeling, then ease of operation is improved, but tamper evidence capability deteriorates

Engineering Contradiction:

Improveease of peelingVSAvoidtamper evidence

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first layer is designed as a disposable element that can be irreversibly disengaged to reveal the second layer with the second code. This disposable approach allows easy peeling through heat application while ensuring tamper evidence, as the irreversible disengagement exposes the hidden second code that indicates the label has been compromised.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

The system comprises of a security label engaged to a package. The label comprises of a first layer with a first code and a second layer with a second code. The first layer is disposed over the second layer in a way that at least a portion of the second code on the second layer is covered by the first layer. The second code on the second layer is revealed upon irreversibly disengaging the first layer from the package. The first code is associated with a first information and the second code is associated with a second information. The second code on the second layer is associated with the first code on the first layer. These codes are authentication-wise interlinked and as one single label which can be pre-applied on product-label and still extended authentication challenge like refill-evidence or tamper-evidence in addition to basic counterfeit-evidence.
