Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional IoT devices are used with poor hardware specifications, then device complexity is reduced and ease of manufacture is improved, but security reliability deteriorates making devices vulnerable to hacking
Solution Approach 1:
The patent introduces a SIM card apparatus as an intermediary security component that mediates between the control server and the IoT device. The SIM card contains a verification module that independently verifies authentication virtual codes, acting as a security mediator that enhances reliability without requiring the IoT device itself to have complex security hardware.
Solution Approach 2:
The security function is segmented from the main IoT device and placed in a separate SIM card apparatus. This segmentation allows the IoT device to remain simple while the SIM card handles the complex verification operations, resolving the contradiction between device simplicity and security reliability.
2Reliability
If a verification module is added to verify authentication virtual codes, then security reliability is improved, but device complexity and firmware requirements increase
Solution Approach 1:
The SIM card apparatus serves as an intermediary that contains the verification module, eliminating the need to add complex firmware to the relay apparatus or IoT device. The verification functionality is housed in the SIM card, which is a separate, standardized component.
Solution Approach 2:
The SIM card apparatus provides multiple functions including authentication verification, secure communication, and device identification. By making the SIM card universal and multi-functional, the patent avoids adding dedicated security hardware or complex firmware to specific devices.
3Reliability
If authentication virtual code verification is implemented, then security against unauthorized access is improved, but communication protocol complexity and operation difficulty increase
Solution Approach 1:
The SIM card apparatus performs self-service verification by automatically checking authentication virtual codes without requiring manual intervention. The verification module autonomously validates codes received from the control server, maintaining ease of operation while enhancing security.
Solution Approach 2:
The SIM card apparatus performs preliminary verification of authentication codes before commands are executed. This preliminary security check is built into the communication flow, so users experience no additional operational steps while security is enhanced.
