Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage device enables wireless communication function, then data transmission capability is improved, but device complexity increases due to lack of user-accessible interfaces for setting identification IDs and passwords
Solution Approach 1:
The storage device automatically generates identification IDs and passwords for wireless communication without requiring user input. The device serves itself by autonomously creating and managing the credentials needed for wireless connection, eliminating the need for complex user interfaces for setting these parameters.
Solution Approach 2:
A two-dimensional code serves as an intermediary between the storage device and external devices. Instead of requiring direct interaction with complex wireless settings interfaces, the system uses a visual two-dimensional code that encapsulates connection information, which can be easily scanned and processed by external devices to establish wireless communication.
2Ease of operation
If manual input interface for wireless settings is provided, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The two-dimensional code acts as an intermediary that simplifies the wireless connection setup process. Instead of requiring users to manually input identification IDs and passwords through complex interfaces, the system presents a scannable two-dimensional code that external devices can automatically read and use to establish connections, greatly easing operation while maintaining simple device structure.
3Ease of operation
If automatic generation of identification information is implemented, then ease of operation is improved, but security considerations arise from automated credential creation
Solution Approach 1:
The storage device autonomously generates secure identification IDs and passwords through automated processes without user intervention. This self-service approach ensures that credentials are consistently and securely created using built-in security algorithms, while simultaneously improving ease of operation by eliminating manual setup requirements.
Data Source
AI summary
In one embodiment, a storage device that is installable in an electronic apparatus includes a first communication interface for connecting the electronic apparatus to the storage device, a nonvolatile memory for storing data and data management table storing a data size and address information for the data stored in the nonvolatile memory, and a processor configured to change at least one piece of data stored in the nonvolatile memory without changing file management information stored in the data management table. The processor is configured to change the stored data without receiving an instruction to do so from the electronic apparatus through the first interface.
