Solution Overview

Problem

In the manufacturing of display devices, achieving precise alignment and maintaining the accuracy of the adhesive layer thickness between substrates is challenging due to variations in substrate positioning and the complexity of existing adhesion apparatuses, which can degrade the quality of the display device.

Innovation Solution

The apparatus includes a turning section to align substrates, a support section with adjustable distance to maintain positional accuracy, and a pressing mechanism to stabilize the substrate after turning, along with a radiation section for curing the adhesive layer, ensuring precise control over the adhesive layer thickness through measurement and adjustment units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a turning section is added to align substrates, then substrate alignment accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvesubstrate alignment accuracyVSAvoidapparatus structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The apparatus is divided into functionally independent sections: a turning section for substrate alignment, a support section for positioning, and a pressing mechanism for adhesion. Each section operates independently to perform its specific function, allowing the turning section to improve alignment accuracy without requiring the entire apparatus to be redesigned.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The turning section enables dynamic adjustment of substrate orientation and positioning. By allowing rotational and positional movements during the adhesion process, the system achieves precise alignment while maintaining operational flexibility, rather than requiring fixed, complex mechanical structures.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If an adjustable support section is used to maintain positional accuracy, then adhesive layer thickness consistency is improved, but device complexity increases

Engineering Contradiction:
Improveadhesive layer thickness consistencyVSAvoidsupport section complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The support section is configured to preliminarily position and stabilize the substrate before the pressing mechanism applies adhesive. This preliminary positioning ensures that the substrate is correctly aligned and spaced, allowing for consistent adhesive layer thickness without requiring complex real-time adjustment mechanisms during the pressing phase.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The support section acts as an intermediary element between the turning section and the pressing mechanism. It transfers and stabilizes the positional information from the turning section while providing a stable platform for the pressing mechanism, thereby ensuring adhesive layer consistency without directly adding complexity to either the turning or pressing systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If multiple sections are added for precise control, then adhesive layer thickness accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveadhesive layer thickness accuracyVSAvoidapparatus operation simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

Multiple functional sections (turning, support, pressing) are merged into a single integrated apparatus that operates through coordinated movement of substrates. Instead of requiring separate operations for each function, the system combines them into one continuous process where substrates are turned, positioned, and pressed in sequence, maintaining precision while simplifying the overall operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The apparatus is designed with multi-functional components that perform multiple operations. For example, the pressing mechanism not only applies pressure for adhesion but also maintains substrate positioning throughout the process. This multi-functionality reduces the number of separate controls and operations needed, improving ease of use while maintaining adhesive layer thickness accuracy.

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