Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication authentication mechanism is added to storage apparatus, then data security is improved, but device complexity increases
Solution Approach 1:
The patent introduces an authentication flag as an intermediary element that mediates between the wireless communication interface and the nonvolatile memory. This flag acts as a gatekeeper, simplifying the authentication mechanism while maintaining security. The controller checks this single flag state to determine whether to permit or prohibit data access, avoiding the need for complex multi-step authentication protocols.
Solution Approach 2:
The patent changes the state of an authentication flag parameter to control access permissions. By transitioning the flag between set and unset states, the system dynamically adjusts access rights without requiring complex permission management structures. This parameter-based control simplifies the authentication mechanism while ensuring data security.
2Reliability
If authentication flag is stored in nonvolatile memory, then access control reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by designating a specific, dedicated region within the nonvolatile memory for storing the authentication flag. This localized approach ensures that the flag is stored in a controlled, predictable location that can be reliably accessed during authentication operations, without requiring high-precision manufacturing across the entire memory structure.
Solution Approach 2:
The authentication flag is pre-configured in a known initial state during manufacturing or first use. This preliminary action establishes the default access permission state before any authentication operations occur, eliminating the need for complex initialization routines and reducing manufacturing precision requirements.
3Adaptability or versatility
If wireless communication function is integrated into storage apparatus, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by enabling the storage apparatus to operate in multiple modes: traditional wired storage mode and wireless communication mode. The same device can serve both as a conventional storage device connected via physical interface and as a wireless storage device, eliminating the need for separate specialized devices and reducing overall system complexity.
Solution Approach 2:
The patent merges the wireless communication function with the existing storage apparatus architecture by integrating the wireless interface and authentication mechanism into the controller that already manages the nonvolatile memory. This consolidation allows the storage controller to handle both traditional storage operations and wireless communication operations, reducing device complexity through functional integration.
Data Source
AI summary
A storage apparatus includes a first memory, which is nonvolatile, a first controller that controls the first memory, a wireless antenna, a second memory, which is operable based on power supplied from the wireless antenna, and a second controller that is operable based on the power supplied from the wireless antenna, and performs communication using the wireless antenna. When performing communication with an external apparatus using the wireless antenna, the second controller performs authentication of the external apparatus, and stores in the second memory an authentication result indicating whether the authentication succeeded or failed. If the authentication result indicates that the authentication succeeded, the second controller permits reading by the external apparatus of first data from the second memory by communication using the wireless antenna or writing by the external apparatus of second data to the second memory by communication using the wireless antenna.
