Mask Plate Assembly with Shielding Strip for Evaporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mask plates welded on frames are often in different shapes due to varying product arrangements, leading to increased tension and poor flexibility, resulting in uneven evaporation forces and undesirable mixed color effects during the evaporation process.
Innovation Solution
A mask plate assembly comprising a frame with a shielding strip and a mask plate, where the mask plate includes an elongated hole opposite to the shielding strip, reducing the area of the entity region and ensuring even evaporation forces by shielding the elongated hole with the strip, thereby improving flexibility and evaporation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mask plates are welded on frames in different shapes due to varying product arrangements, then adaptability to different products is improved, but tension on the mask plate increases and flexibility deteriorates
Solution Approach 1:
The mask plate is segmented by introducing an elongated hole that divides the solid structure into regions, reducing the overall entity region area and thereby decreasing tension while maintaining adaptability to different product arrangements
Solution Approach 2:
The mask plate design incorporates an elongated hole that changes the physical parameters of the plate, specifically reducing the entity region area and improving flexibility while maintaining the ability to adapt to different shapes and product arrangements
2Adaptability or versatility
If mask plates have increased tension due to different shapes, then adaptability to various configurations is improved, but evaporation force uniformity deteriorates
Solution Approach 1:
The elongated hole segments the mask plate structure, creating a more flexible configuration that allows for uniform evaporation force distribution across different shapes and configurations
Solution Approach 2:
By changing the physical parameters of the mask plate through the elongated hole, the tension is reduced and flexibility is improved, resulting in uniform evaporation force and preventing mixed color effects
3Adaptability or versatility
If mask plates have poor flexibility due to different shapes, then adaptability to various arrangements is improved, but fit between mask plate and evaporation member deteriorates
Solution Approach 1:
The elongated hole segments the mask plate, reducing the entity region area and improving flexibility to achieve better fit with the evaporation member while maintaining arrangement adaptability
Solution Approach 2:
The physical parameter change introduced by the elongated hole improves the mask plate's flexibility and fit characteristics without compromising its ability to adapt to various arrangements
