Solution Overview

Problem

Existing methods for tagging metal products from iron and steel processes are cumbersome and time-consuming, requiring double manipulation operations for applying tags and support elements, which complicates manual and automated application processes.

Innovation Solution

A tag with a metal plate-like structure and a junction element having a through-opening with radial interference protrusions, allowing for interference fit and integration with a gripping portion for robotic or mechanical arm handling, simplifying the attachment and welding process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate manipulation of tag and support element is used, then secure attachment is achieved, but operation complexity and time increase

Engineering Contradiction:
Improvetag application operationVSAvoidmanipulation process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The tag and support element are merged into a single integrated component. The tag body directly incorporates the support element structure, eliminating the need for separate manipulation and attachment operations. This integration simplifies the操作流程 while maintaining secure attachment capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated tag structure serves multiple functions simultaneously: it provides identification information through its reading surface, structural support through the integrated support element, and attachment capability through the unified design. This multi-functionality reduces the number of separate components needed.

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

2Productivity

If integrated tag with interference fit is used, then attachment speed increases, but manufacturing precision requirements increase

Engineering Contradiction:
Improvetag affixing speedVSAvoidinterference protrusion fit
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The interference fit features (protrusions and corresponding recesses) are localized to specific regions of the tag structure rather than requiring precision across the entire component. This allows high-speed manufacturing methods to be used while maintaining adequate fit precision only where needed for the interference connection.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The design incorporates tolerance compensation through the interference fit geometry, where slight variations in manufacturing dimensions are absorbed by the elastic deformation capability of the interference connection. This allows faster manufacturing processes with relaxed tolerances to produce functional tags.

Inventive Principle:
Principle #35Parameter changes
