External Storage Medium Processing Device Startup Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with removable external storage media, such as USB ports or card slots, unnecessarily notify users of attached media upon startup, even if the media was already present before shutdown, causing obstructive operations.
Innovation Solution
An external storage medium processing device that stores identification information of attached media during shutdown and determines whether to notify the user of attachment at startup based on this information, avoiding unnecessary notifications by matching pre-stored and current identification data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification of attachment is performed every time the device is turned on with an external storage medium attached, then the user is notified of all attached media, but unnecessary notifications occur when the same medium was already attached before shutdown, obstructing user operation
Solution Approach 1:
The system performs preliminary action by storing identification information of the external storage medium before shutdown occurs. During startup, this pre-stored information is compared with currently attached media to determine whether notification is necessary, avoiding unnecessary notifications while ensuring reliable detection of new media attachments.
Solution Approach 2:
The system implements feedback by comparing the identification information of currently attached external storage media with previously stored identification information. Based on this comparison result, the notification decision is made - if the IDs match, no notification is performed; if they differ, notification is triggered. This feedback mechanism resolves the contradiction between reliable notification and operational efficiency.
2Ease of operation
If the device stores and compares identification information to avoid unnecessary notifications, then user operation efficiency is improved, but the device complexity increases due to additional storage and comparison functions
Solution Approach 1:
The control unit stores identification information of the external storage medium in a predetermined storage area before shutdown. This preliminary storage action enables the system to quickly determine during startup whether notification is needed by simply comparing IDs, avoiding the need for complex analysis while improving operational efficiency.
Solution Approach 2:
The system creates a copy of the identification information from the external storage medium and stores it in the predetermined storage area of the control unit. This copying mechanism allows for simple comparison operations during startup without requiring complex processing, thus improving user operation efficiency while adding minimal system complexity.

AI summary
An external storage medium processing device includes a plurality of receiving units to and from which the external storage medium can be attached and detached. Further, when detecting that the external storage medium is attached to the receiving unit at the time of startup, a control unit collates identification information stored in a storage unit with identification information acquired from the external storage medium. A notification unit does not perform notification of attachment if identification information is matched and, if not, performs notification of attachment.
