Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical locks with keys are used to secure merchandise security devices, then the security device can be locked and unlocked, but the system is vulnerable to shoplifting attempts and lacks centralized control
Solution Approach 1:
The patent replaces mechanical lock and key systems with electronic key devices that communicate wirelessly with security devices. The electronic key device contains a processor and memory that store security codes and serial numbers, eliminating the need for mechanical locking mechanisms while providing enhanced security through electronic authentication and centralized control capabilities.
Solution Approach 2:
The electronic key device serves multiple functions: it stores security codes and serial numbers, communicates wirelessly with security devices, provides centralized control over multiple locations, and enables real-time monitoring. This multi-functional approach consolidates what would otherwise require separate mechanical locks, keys, and monitoring systems.
2Ease of operation
If electronic keys with centralized control are implemented, then security management is improved and real-time monitoring is enabled, but the device complexity and programming requirements increase
Solution Approach 1:
The electronic key device automatically performs authentication by comparing stored security codes and serial numbers with those of the security device. The system self-manages the locking and unlocking processes without requiring manual intervention or complex programming by the user, simplifying operation while maintaining security.
Solution Approach 2:
Security codes and serial numbers are pre-programmed into the electronic key device before use. This preliminary configuration enables the device to automatically authenticate and control security devices without requiring on-site programming, reducing operational complexity while maintaining centralized control capabilities.
3Reliability
If serial numbers are programmed in electronic keys for authorization, then only authorized keys can operate security devices, but the programming process becomes more complex
Solution Approach 1:
The patent replaces manual programming processes with wireless electronic communication. The electronic key device and security device exchange authentication data electronically, eliminating the need for manual serial number entry or complex programming procedures. This maintains high authorization security while significantly simplifying the programming process.
