Substrate Container Buffer Assembly for Vibration and Dust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate containers face issues such as substrate damage from vertical vibrations, loosening of assembly components, friction-induced dust generation, and loosening due to thermal expansion and contraction.
Innovation Solution
The substrate container incorporates a door assembly, a support assembly, and elastic buffer elements to mitigate these issues. The elastic buffer elements are placed between rigid elements to provide a buffer force and appropriate frictional force, preventing impact and dust generation, and accommodating thermal deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rigid structures are used in substrate container, then structural strength is maintained, but vibration and friction cause substrate damage and component loosening
Solution Approach 1:
The patent applies elastic buffer elements at connection positions between components and at substrate support positions. These buffer elements are pre-installed to provide cushioning before vibration impacts occur, preventing direct transmission of vibration forces to substrates and components, thereby resolving the contradiction between maintaining structural strength and protecting against vibration damage.
Solution Approach 2:
The patent changes the mechanical parameters of connection and support structures by introducing elastic buffer elements with specific elasticity values. This transforms rigid connections into flexible connections that can absorb vibration energy, changing the system's response to vibration from rigid transmission to elastic absorption, thus protecting substrates while maintaining structural integrity.
2Stability of the object's composition
If tight fitting components are used in substrate container, then assembly stability is improved, but friction generates dust during transportation and positioning
Solution Approach 1:
The patent introduces elastic buffer elements as intermediary components between tightly fitting parts. These buffer elements maintain the tight fitting necessary for assembly stability while providing a protective layer that prevents direct friction between rigid surfaces, thereby eliminating dust generation during transportation and positioning operations.
3Strength
If rigid support structures are used, then load bearing capacity is maintained, but thermal expansion causes component loosening
Solution Approach 1:
The patent explicitly addresses thermal expansion by using elastic buffer elements in support structures. These buffer elements have elastic properties that allow them to expand and contract with temperature changes while maintaining connection integrity. This resolves the contradiction by providing both load bearing capacity through the rigid support structure and accommodation of thermal expansion through the elastic buffer, preventing component loosening.

AI summary
A substrate container includes a container body having a storage space and an opening in communication with the storage, a door body disposed at the opening, a limiter disposed on the door body and facing the opening, a supporter disposed on one side of the storage space, and at least two elastic buffer elements tightly disposed between the door body and the limiter and between the supporter and the container body, respectively. A door assembly of a substrate container, a support assembly of a substrate container and an elastic buffer element used in a substrate container are further provided. The elastic buffer element is applied between any two rigid elements in the substrate container to provide a buffer force and an appropriate frictional force, so as to alleviate the problems of impact and dust generated between the rigid elements.
