Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic access control systems are used to improve usability, then ease of operation is improved, but security is compromised
Solution Approach 1:
The system divides access control into two independent parts: a stationary security module containing the security key stored in the container, and a mobile authorization key delivery device that provides authorization keys temporarily. This segmentation ensures that even if the mobile device is lost, the security key remains secure in the container, resolving the contradiction between ease of operation and security.
Solution Approach 2:
The system performs preliminary actions by pre-storing authorization keys in the mobile device before delivery, and by having the container continuously generate and store security keys. This allows the delivery person to access the container immediately upon arrival without requiring real-time communication or complex authentication procedures, improving ease of operation while maintaining security through pre-established key pairs.
2Reliability
If mechanical locking systems are used to ensure security, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces mechanical locking systems with an electronic access control system. The container includes an electronic locking mechanism that can be unlocked by receiving a signal from the authorization module after successful key comparison. This substitution eliminates the need for physical keys and mechanical locks, improving ease of operation while maintaining security through electronic authentication.
3Ease of operation
If authorization keys are stored in the mobile device to improve usability, then ease of operation is improved, but security is compromised
Solution Approach 1:
The system segments the key storage function: the mobile device stores only temporary authorization keys that are valid for specific containers and expire after use, while the container itself stores the permanent security key. This segmentation limits the impact of key theft to only the temporary authorization keys, which can be regenerated, thereby maintaining both ease of operation and security.
Solution Approach 2:
The system provides beforehand cushioning by implementing multiple security layers: the authorization keys in the mobile device are encrypted, have expiration times, and are tied to specific container identification features. The container's security key remains independent and cannot be compromised by theft of the mobile device. This cushioning against potential security breaches allows the system to maintain ease of operation without sacrificing security.
