Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus supports various input devices for versatile operation, then the adaptability is improved, but the security vulnerability increases due to unauthorized operation risks
Solution Approach 1:
The system performs preliminary authentication before executing input operations. The authentication module pre-verifies whether the input operation originates from an authorized device or user, and only allows execution of operations that have passed authentication. This prevents unauthorized operations while maintaining support for multiple legitimate input devices.
Solution Approach 2:
An authentication module is introduced as an intermediary between the input device and the display apparatus execution mechanism. This intermediary layer verifies the legitimacy of each input operation, allowing the system to maintain versatility in accepting various input devices while ensuring security through centralized authentication control.
2Reliability
If the system filters out unauthorized input operations in safe mode, then the security is improved, but the operational flexibility deteriorates
Solution Approach 1:
The system dynamically adjusts its operational mode between safe mode and normal mode. In safe mode, strict authentication filtering is applied to prevent unauthorized operations. In normal mode, the system relaxes restrictions to allow greater operational flexibility. This dynamic switching resolves the contradiction by adapting the security level to the current operational context.
Solution Approach 2:
The authentication threshold parameter is changed based on the operational mode. In safe mode, the authentication requirement parameter is set to high, filtering out unauthorized operations. In normal mode, the parameter is lowered to allow more flexible operation. This parameter adjustment mechanism enables the system to balance security and flexibility as needed.
