Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-factor authentication is implemented to enhance security, then the false acceptance rate decreases significantly, but the complexity of the authentication process increases requiring multiple user inputs
Solution Approach 1:
Light sources are introduced as intermediary visual aids between the authentication system and the user. These lights provide real-time feedback and guidance, mediating the complex authentication process by indicating which input devices are active and what actions are required, thereby reducing user confusion without compromising security
Solution Approach 2:
The system implements feedback mechanisms where light sources provide continuous visual information about the authentication state. The lights respond to user inputs and system events in real-time, guiding users through the multi-factor authentication process and confirming when credentials are successfully verified
2Reliability
If multiple authentication factors are required, then security is enhanced, but user guidance and notification become necessary to prevent confusion
Solution Approach 1:
Visual feedback through light sources serves as an intermediary communication channel between the authentication system and user. The lights translate system states into intuitive visual cues, making the authentication process easier to understand and operate while maintaining high security requirements
Solution Approach 2:
The system utilizes different light states and patterns to communicate authentication status and guide user actions. Visual feedback through illumination changes provides intuitive guidance without requiring complex text or audio instructions, enhancing ease of operation
