Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus supports various input devices for intelligent terminal operations, then the adaptability and ease of operation are improved, but the security vulnerability to unauthorized operation increases
Solution Approach 1:
The system pre-configures multiple operating modes (normal mode, safe mode, kiosk mode) and authentication mechanisms before unauthorized access attempts occur. The safe mode is pre-established with restricted functionality, and authentication credentials are pre-set to control access between modes, preventing unauthorized changes before they can happen.
Solution Approach 2:
The display apparatus dynamically switches between different operating modes based on authentication results and operational requirements. The system can transition from normal mode to safe mode or kiosk mode during operation, and the set of accessible input devices and functions changes dynamically according to the current mode, providing adaptability while maintaining security.
2Reliability
If multiple operating modes are implemented to enhance security, then the security against unauthorized operation is improved, but the device complexity increases
Solution Approach 1:
The control logic is segmented into distinct operating modes (normal mode, safe mode, kiosk mode), each with its own predefined set of accessible functions and input devices. This segmentation isolates security-critical functions in specific modes, making the complexity manageable by treating each mode as a separate operational context rather than one monolithic complex system.
Solution Approach 2:
An intermediary control mechanism (authentication system and mode manager) mediates between the user/input devices and the display apparatus functions. This intermediary layer handles the complexity of mode switching and access control, shielding the underlying complexity from users while providing a simple interface for mode transitions through authentication.
3Reliability
If preset operations with key combinations are required for mode switching, then the security is improved, but the ease of operation deteriorates
Solution Approach 1:
Different operation complexity requirements are applied locally to different functions and modes. Critical mode transitions (e.g., entering or exiting safe mode) require authenticated key combination operations, while routine operations within a mode maintain simple single-key or touch interactions. This local differentiation of operation complexity provides security where needed while preserving ease of use for normal operations.
