Substrate Container Locking Structure for Simpler Mold Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing substrate storing containers require a complex mold structure due to the central locked portion, leading to reduced production efficiency and extended cooling times, as the central locked portion complicates the mold operation and hinders optimal placement of cooling circuits.
Innovation Solution
A substrate storing container design with a central fixed member that is removably attached to the container main body, avoiding undercuts and complex mold structures, allowing for efficient fitting and optimal placement of cooling circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the central locked portion is integrated into the container main body, then the container can be securely fixed to the load port, but the mold structure becomes complex requiring slide structures
Solution Approach 1:
The central locked portion is separated from the container main body and designed as a removable attachment. This segmentation allows the container main body to be molded without complex slide structures, while the locked portion can be separately attached to provide the necessary fixing function. The separation resolves the contradiction by eliminating the need for complex integrated mold structures while maintaining secure fixation capability.
2Manufacturing precision
If the mold structure is complex with slide structures, then the central locked portion can be formed, but the mold operation speed must be reduced
Solution Approach 1:
By segmenting the central locked portion as a separate removable component rather than an integrated feature, the mold structure is simplified to avoid slide structures. This enables faster mold operation and shorter molding cycles while still achieving precise formation of the locked portion through separate attachment processes.
3Manufacturing precision
If the mold structure is complex, then the central locked portion can be formed, but the cooling circuit placement becomes difficult extending cooling time
Solution Approach 1:
The segmentation of the central locked portion simplifies the mold structure, enabling optimal placement of cooling circuits within the mold. This allows for efficient heat dissipation and reduced cooling time, as the cooling circuit can be positioned at the most effective locations without being constrained by complex slide structure requirements.

AI summary
The container main body includes a tubular wall portion having an opening circumferential portion provided at one end portion and the other end portion being closed, the opening circumferential portion having a container main body opening portion formed therein. The substrate storing space can store a substrate and communicates with the container main body opening portion. A central fixed member is provided to the wall portion of the container main body so as to be removably attached to the wall portion of the container main body. The central fixed member is configured to be locked and fixed to an alignment portion provided at a load port for conveying the substrate stored in the substrate storing space to a processing apparatus.
