Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional evaporation apparatuses lack flexibility to accommodate different organic materials, requiring repeated reconstruction and testing, which is time-consuming and resource-intensive due to oxidation of materials when the chamber is opened.
Innovation Solution
An evaporation apparatus with a moving device below the evaporation chamber that adjusts the relative height between the evaporation source and regulating plates, allowing for flexible evaporation conditions without reconstruction, using a servo motor control system to actuate the moving device and adjust the evaporation source or regulating plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the evaporation apparatus structure is determined according to a specific organic material, then the evaporation performance is optimized, but the apparatus cannot accommodate different organic materials without reconstruction
Solution Approach 1:
The patent applies the dynamics principle by making the regulating plates movable rather than fixed. The regulating plates can be adjusted to different positions and angles, allowing the evaporation apparatus to adapt to different organic materials while maintaining optimal evaporation performance. This dynamic adjustment capability resolves the contradiction between optimized performance for a specific material and versatility for multiple materials.
2Adaptability or versatility
If the chamber is opened for reconstruction when changing organic materials, then the apparatus can be reconfigured, but the organic material oxidizes and must be replaced
Solution Approach 1:
The movable regulating plates allow configuration changes without opening the chamber, preventing material oxidation and loss.
Solution Approach 2:
The regulating plates are pre-designed to be adjustable, allowing configuration changes to be made without chamber opening. This preliminary design feature prevents the need to open the chamber for material replacement, thus preventing oxidation and loss of organic material.
3Adaptability or versatility
If the chamber is opened multiple times for reconstruction and testing, then the apparatus can be optimized for different materials, but the process becomes time-consuming
Solution Approach 1:
The dynamic adjustable regulating plates eliminate the need for repeated chamber opening, reconstruction, and testing. The plates can be reconfigured for different materials without breaking vacuum, significantly reducing the time required for material adaptation.
Solution Approach 2:
The adjustable regulating plates are pre-configured to allow easy repositioning and angle adjustment. This preliminary design enables rapid adaptation to different organic materials without time-consuming reconstruction and testing cycles.

Implementation Method 1
When performing vacuum evaporation, the organic material in the evaporation source 21 is vaporized into organic material molecules and forms an organic thin film on the substrate 1
Implementation Method 2
the moving device actuates the evaporation source to move up and down, thereby changing a relative height between the evaporation source and the regulating plates
