Solution Overview

Problem

Existing marking systems require carriers for marking objects, which increase costs and can lead to unwanted emissions due to incorrect operating parameters, particularly in laser marking systems.

Innovation Solution

A marking system with a detection device to capture identification information and a control device to authenticate and control the marking process, allowing for reliable marking without carriers and preventing unauthorized marking by adjusting operating parameters based on authentication results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a carrier is used to hold marking objects, then the objects can be fed into the marking system, but the cost increases and the carrier serves no purpose after marking

Engineering Contradiction:
Improvefeeding marking objectsVSAvoidcost of carrier
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent extracts the identification function from the carrier by placing identification information directly on the marking object itself. This eliminates the need for a separate carrier, as the marking object can be individually identified and processed without requiring a film or tray to hold multiple objects.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The marking object serves multiple functions: it is both the item to be marked and the carrier of its own identification information. The identification information is integrated into the marking object itself, allowing the object to identify itself during the marking process without requiring an external carrier.

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

2Manufacturing precision

If operating parameters are adjusted for different marking objects, then marking accuracy improves, but incorrect parameters can cause excessive emissions

Engineering Contradiction:
Improvemarking accuracyVSAvoidemissions
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary authentication of the marking object's identification information before the marking process begins. The control device verifies the identification data and determines the correct operating parameters in advance, ensuring that appropriate parameters are used from the start and preventing excessive emissions caused by incorrect parameter selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the detection device that reads the identification information on each marking object to automatically adjust the operating parameters. This closed-loop control ensures that the marking parameters match the specific requirements of each object, preventing emissions caused by mismatched parameters.

Inventive Principle:
Principle #23Feedback

3Reliability

If authentication is performed before marking, then unauthorized marking is prevented, but the process time increases

Engineering Contradiction:
ImproveauthenticationVSAvoidprocess time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The authentication of identification information is performed as a preliminary step before the marking process begins. The control device verifies the identification data and determines parameter authenticity in advance, which prevents unauthorized marking while integrating smoothly into the workflow without significant time loss.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If identification information is read from marking objects, then carrier-free processing is enabled, but detection accuracy must be ensured

Engineering Contradiction:
Improvecarrier-free processingVSAvoiddetection accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent uses an intermediary detection device as a mediator between the marking object and the control device. This detection device reads the identification information from the marking object and transmits it to the control device, enabling carrier-free processing while ensuring accurate detection through a dedicated reading mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)
