Solution Overview
Problem
Existing vacuum evaporating apparatuses face challenges in efficiently controlling the evaporation process and maintaining a stable evaporation angle for mobile electronic devices, particularly in miniaturized systems where precise control of evaporating materials is crucial for display technologies like organic light-emitting diodes.
Innovation Solution
A vacuum evaporating apparatus is designed with a driving unit, linear-moving and rotational-moving portions, and a shutter portion with a mesh surface, incorporating shock-absorbing mechanisms and guides to precisely control the movement and evaporation process, ensuring stable evaporation angles and efficient material distribution.

Engineering Contradiction Analysis
1Manufacturing precision
If a conventional vacuum evaporating apparatus is used, then the evaporation process can be performed, but the evaporation angle cannot be maintained stably and material deviation occurs
Solution Approach 1:
The patent applies dynamics by making the shutter portion rotatable around a rotation axis. The rotation angle of the shutter portion is adjusted according to the position of the linear moving portion, enabling dynamic adjustment of the evaporation angle to maintain stability throughout the evaporation process. This dynamic mechanism ensures that the evaporation angle remains consistent even as the linear moving portion changes position, thereby preventing material deviation and improving manufacturing precision.
2Manufacturing precision
If the shutter portion is made larger to control material flow, then material distribution improves, but the apparatus size increases
Solution Approach 1:
The shutter portion is segmented into a first shutter body portion and a second shutter body portion that are bent relative to each other. This segmentation allows the shutter to effectively control material flow through its mesh structure and rotation capability while maintaining a compact form factor. The bent configuration enables the shutter to cover the necessary area for material control without requiring a large overall apparatus volume, thus resolving the contradiction between material distribution control and apparatus size.
