Mask Package Buffer Structure for FMM Impact and Pressure Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging structures for fine metal masks (FMM) in the display industry, such as those used in OLED panel manufacturing, fail to prevent damage from impact or squeeze during transportation, and do not protect against internal pressure caused by external stress transfer.
Innovation Solution
A mask package comprising a package body with an accommodating space, a cover body, and a first buffer, along with optional second buffer, provides anti-impact protection and prevents shear stress by using a flexible first buffer that absorbs external forces, while the package body offers structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a general package with upper plate and lower plate is used, then the packaging structure is simple, but the FMM may be squeezed and damaged during transportation
Solution Approach 1:
The packaging structure is divided into multiple functional components: package body, cover body, first buffer, and second buffer. Each component serves a specific function - the package body provides structural support, the buffers provide cushioning and stress absorption, and the cover body provides closure. This segmentation allows the system to achieve both simplicity in assembly and high reliability in protection.
Solution Approach 2:
The first buffer and second buffer are positioned between the mask and the package body/cover body to provide beforehand cushioning. These buffers absorb external impacts and internal pressure before they can reach the mask, preventing damage during transportation while maintaining a relatively simple overall structure.
2Ease of manufacture
If conventional packaging is used, then the packaging cost is low, but internal pressure caused by external stress transfer damages the mask
Solution Approach 1:
The first buffer and second buffer act as intermediary elements between the external environment and the mask. These buffers mediate the transfer of external stress, absorbing and dissipating forces before they can penetrate through to the mask, thereby eliminating internal pressure damage while maintaining cost-effective packaging.
Solution Approach 2:
The packaging system changes the mechanical parameters of stress transmission by introducing buffer materials with specific elasticity and damping properties. These buffers modify the stress distribution and absorption characteristics, transforming harmful concentrated stresses into distributed, absorbed forces that protect the mask while remaining cost-effective to manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents damage to the mask and maintains its original state by absorbing external impacts and internal pressure, ensuring the mask remains intact during transportation.
Implementation Method 1
The first buffer has a first length and a first width, and is disposed between the package body and the cover body... the first buffer absorbs external forces

AI summary
A mask package comprises a package body, a cover body and a first buffer. The package body has a bottom and a side wall, where the side wall has a top; the side wall is connected with the bottom, the top is located on a side opposite to a side where the side wall is connected with the bottom, and the side wall surrounds the bottom to form an accommodating space. The cover body is disposed on the top of the side wall and masks the accommodating space. The first buffer has a first length and a first width, and is disposed between the package body and the cover body, where the accommodating space has a second length and a second width, the second length is less than the first length and the second width is less than the first width.
