Solution Overview

Problem

Existing laser label readers lack the capability to authenticate the authenticity and security of products, leading to issues with counterfeit detection and product verification.

Innovation Solution

A laser label identification device that processes laser label images to extract texture features, which are matched against stored standard images to verify authenticity, using a recognition module and machine learning models to determine product genuineness and lot information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing readers focus on improving their ability to identify images of distorted labels, then label reading capability is improved, but the ability to authenticate product authenticity and security remains insufficient

Engineering Contradiction:
Improvelabel reading capabilityVSAvoidproduct authentication capability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent segments the label verification process into two independent modules: one for reading distorted label images and another for extracting and verifying texture features. This segmentation allows each module to specialize in its function, improving both label reading capability and authentication reliability without mutual interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reader device is enhanced with multi-functionality by integrating both label reading and texture feature verification capabilities into a single system. The device can now perform not only traditional label recognition but also authenticity authentication through texture analysis, making it a universal verification tool.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If laser marking is used to create labels, then marking speed is improved and environmental pollution is reduced, but the ability to verify product authenticity through the labels is insufficient

Engineering Contradiction:
Improvemarking speedVSAvoidauthenticity verification capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by embedding unique texture features into the laser-marked labels during the manufacturing process. These features are created automatically as part of the laser marking operation, so that when the product reaches the consumer, the authenticity verification can be performed immediately without requiring additional manufacturing steps.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If traditional marking processes such as chemical corrosion or ink jetting are used, then environmental pollution increases and marking speed decreases, but authenticity verification capability is also limited

Engineering Contradiction:
Improveenvironmental pollutionVSAvoidauthenticity verification capability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent replaces traditional chemical or mechanical marking processes with laser marking, which uses optical energy instead of chemicals or mechanical contact. This substitution eliminates environmental pollution and improves marking speed while simultaneously enabling authenticity verification through the unique texture features that laser marking naturally produces.

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