Solution Overview

Problem

Conventional organic light-emitting components face accelerated degradation due to reactions with water and oxygen, which is exacerbated by electrical conductive lines acting as permeation channels during encapsulation, making it difficult to achieve a satisfactory seal.

Innovation Solution

The method involves producing an organic light-emitting component with a substrate and a layer stack encapsulated in a way that eliminates external electrical contact surfaces, using a receiver device to convert an alternating electromagnetic field into electrical energy, and employing an encapsulation that completely surrounds the component to prevent contact with corrosive substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electrical conductive lines are used to lead outward from the component through or under encapsulation, then electrical contact to the component is enabled, but the encapsulation seal is compromised and water/oxygen penetration occurs

Engineering Contradiction:

Improveelectrical contactVSAvoidencapsulation seal

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical/electrical contact system (conductive lines penetrating encapsulation) with an electromagnetic field-based energy transfer system. The antenna coil transfers energy wirelessly to the organic light-emitting component, eliminating the need for conductive lines that would compromise the encapsulation seal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an antenna coil as an intermediary device that enables energy transfer without direct physical contact. The antenna coil acts as a mediator between the power source and the organic light-emitting component, allowing energy transmission through electromagnetic fields while maintaining the integrity of the encapsulation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If encapsulation is applied to protect organic materials from water and oxygen, then degradation is reduced, but electrical contact surfaces must be exposed which creates permeation channels

Engineering Contradiction:

Improveprotection from degradationVSAvoidpermeation channels

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical contact system requiring exposed electrical surfaces with an electromagnetic field-based wireless power transfer system. This substitution eliminates permeation channels while maintaining both protection and electrical functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the electrical contact function from the physical structure by using wireless electromagnetic energy transfer. The harmful permeation channels are eliminated by taking out the need for physical conductive lines that penetrate the encapsulation.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If conventional encapsulation with external contact surfaces is used, then electrical connection is achieved, but production time and costs increase

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent replaces complex mechanical electrical connection processes with simpler wireless electromagnetic energy transfer. This substitution reduces production steps, eliminates the need for precise alignment of contact surfaces, and decreases overall production time and costs.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
