Solution Overview

Problem

Existing optoelectronic components are difficult to identify and expensive to produce, particularly in a form that integrates a magnetic structure for unique identification while maintaining a visually uniform appearance.

Innovation Solution

An optoelectronic component with a magnetic structure covered by a coating that allows for machine-readable identification, integrated in a space-saving manner, using a matrix material with magnetic particles or strips, and a cover body to ensure the magnetic structure is not optically visible, combined with radiation-emitting semiconductor chips for electromagnetic radiation emission or reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a magnetic structure is integrated into the optoelectronic component for unique identification, then identification capability and data density are improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improveidentification capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The magnetic structure is integrated within the existing optoelectronic component structure, nesting the identification function inside the component housing or substrate. This allows the magnetic structure to be part of the component without adding external complexity, resolving the contradiction between identification capability and manufacturing complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The magnetic structure serves multiple purposes: providing unique identification through machine-readable patterns and potentially serving as part of the structural or functional architecture of the optoelectronic component. This multi-functionality reduces the need for separate identification components, thereby reducing overall manufacturing complexity

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

2Loss of information

If a magnetic structure is integrated into the optoelectronic component for unique identification, then identification capability is improved, but production cost increases

Engineering Contradiction:
Improveidentification capabilityVSAvoidproduction cost
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The magnetic structure is manufactured as an integrated part of the optoelectronic component during the same production process, rather than as a separate component requiring additional assembly steps. This nesting approach eliminates extra manufacturing operations and reduces production cost

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The manufacturing processes for the optoelectronic component and the magnetic structure are merged into a single integrated production flow. The magnetic structure is formed using the same lithography, deposition, and fabrication steps already required for the optoelectronic devices, thereby eliminating additional production costs

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If the magnetic structure is made visible for identification purposes, then identification capability is improved, but visual uniformity and aesthetic appearance deteriorate

Engineering Contradiction:
Improveidentification capabilityVSAvoidvisual uniformity
Core Design Contradiction:
Loss of informationVSShape

Solution Approach 1:

The magnetic structure is replicated or reflected in the coating layer, creating an optical illusion where the magnetic pattern appears visible without actually exposing the magnetic material. This copying approach provides machine-readable identification while maintaining visual uniformity for human observers

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The coating layer is designed with specific optical properties that allow it to interact with light in a way that creates machine-readable patterns without visually disturbing the uniform appearance. The coating may use interference effects, absorption characteristics, or refractive index variations to encode information that is detectable by machines but invisible or indistinguishable to human eyes

Inventive Principle:
Principle #32Color changes

4Loss of information

If the magnetic structure is exposed for identification, then identification capability is improved, but the magnetic structure becomes vulnerable to external influences

Engineering Contradiction:
Improveidentification capabilityVSAvoidvulnerability to external influences
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The coating layer creates an optical copy or representation of the magnetic structure that provides identification capability without exposing the actual magnetic material. The magnetic structure remains protected beneath the coating, while the coating's optical properties enable machine-readable identification

Inventive Principle:
Principle #26Copying

Solution Approach 2:

A protective coating layer is applied over the magnetic structure, forming a thin film barrier that protects the magnetic material from corrosion, oxidation, and other external influences. The coating is designed with specific optical properties that allow machine-readable identification while maintaining the protective function

Inventive Principle:
Principle #30Flexible shells and thin films
