Substrate Container Lid Holder Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current substrate containers experience continuous positional deviation of substrates due to repeated attachment and detachment of the lid, leading to inaccurate substrate positioning and decreased throughput in transportation and treatment processes.
Innovation Solution
A substrate container design featuring a casing with a lid, a lid holder, and a substrate separating mechanism that includes a contact part movable relative to the lid holder, allowing precise control of substrate positioning by attaching and detaching the lid while ensuring the substrates are held securely during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lid is repeatedly attached and detached from the casing, then the substrates can be transported from the casing, but the substrates experience continuous positional deviation and cannot be positioned accurately
Solution Approach 1:
The lid holder is pre-configured with holding portions that engage with the substrates before the lid is fully attached. This preliminary action secures the substrates in position, preventing deviation during subsequent attachment-detachment cycles while maintaining transportation capability
Solution Approach 2:
The lid holder acts as an intermediary component between the lid and the substrates. It provides a stable interface that holds the substrates firmly during lid attachment/detachment operations, eliminating direct contact forces that cause positional deviation while enabling substrate transportation
2Productivity
If the lid is repeatedly attached and detached from the casing, then the substrates can be transported, but the substrate treatment process is delayed and throughput decreases
Solution Approach 1:
The lid holder secures substrates in advance before lid attachment, eliminating the need for re-positioning operations after each detachment. This preliminary securing action streamlines the transportation process and reduces idle time during substrate treatment operations
Solution Approach 2:
The lid holder maintains continuous substrate holding capability throughout the lid attachment-detachment cycle. This continuous action ensures substrates remain properly positioned without interruption, eliminating delays in the substrate treatment process while maintaining transportation efficiency
3Manufacturing precision
If a lid holder is added to hold substrate ends, then substrate positioning is improved, but the device complexity increases
Solution Approach 1:
The lid holder is designed to perform multiple functions: it holds substrate ends for positioning, provides a mounting interface for the substrate separating mechanism, and structurally connects the lid to the casing. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved positioning accuracy

AI summary
A substrate container includes a casing, a rack, a lid, a lid holder, and a substrate separating mechanism. The casing has on its front face an opening. The substrate separating mechanism has a contact part that directly contacts substrates. The contact part is movable relative to the lid holder. The lid moves forward to the opening, and the contact part moves backward relative to the lid holder, whereby the lid holder holds ends of the substrates. The lid moves backward from the opening, and the contact part moves forward to the lid holder, whereby the substrate separating mechanism separates the substrates from the lid holder.
