Substrate Processing Controller Interface for Safe Storage Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate processing apparatuses face difficulties in preventing improper removal of removable storage media, such as USB flash drives, during data transfer, leading to potential data loss due to lack of clear indication of ongoing writing processes.
Innovation Solution
A substrate processing apparatus is designed with a controller that displays a manipulation screen indicating the attachment status of external storage devices, enabling or disabling buttons accordingly, and prompting users to safely remove the devices only after data writing is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data are written to USB flash memory using cache memory with delayed writing timing, then data transfer efficiency is improved, but the risk of data loss increases when the USB flash memory is removed during writing
Solution Approach 1:
The system provides visual feedback through icons on the manipulation screen to indicate the data writing state. When data is being written to the USB flash memory, a specific icon is displayed to warn users not to remove the device. This feedback mechanism allows the system to maintain delayed writing for efficiency while providing users with information needed to prevent data loss.
Solution Approach 2:
The controller acts as an intermediary between the cache memory system and the USB flash memory. It manages the delayed writing process and provides status information to the user interface, mediating between the need for efficient data transfer and the need to prevent accidental data loss during the writing process.
2Reliability
If a function icon for checking data writing states is added to the manipulation screen, then data safety is improved, but device complexity increases
Solution Approach 1:
The system uses different icons or icon states to represent different data writing conditions. This visual indication method provides clear information about the writing state without requiring complex text descriptions or multiple separate indicators, thus improving data safety while minimizing the increase in interface complexity.

AI summary
A substrate processing apparatus gives a user notice to prevent removal of a storage medium and provides a screen for determining whether the storage medium is removable. The apparatus controls display of the screen for manipulating substrate processing information and includes a part to which an external storage device is attached. The screen includes: a title panel displayed at an upper region of the screen; an information panel controlling or monitoring a task; and a navigation panel at a lower region of the screen. When the external storage device is attached to the part, an external storage device remove button is enabled by displaying the remove button on the navigation panel to indicate the external storage device is attached to the part. When the external storage device is not attached to the part, the remove button is disabled by displaying the remove button in a like color as the background.
