Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing access control devices are upgraded to support mobile terminal devices, then the ability to read access identifiers from mobile terminals is improved, but the device complexity and cost increase
Solution Approach 1:
The system is divided into three independent components: the existing access control device, the extended reading module (radio interface), and the access control system. The extended reading module handles mobile terminal communication while the access control device maintains its original functionality, allowing versatility improvement without increasing the complexity of individual components.
Solution Approach 2:
The extended reading module acts as an intermediary component that bridges mobile terminals and the access control system. It receives access identifiers from mobile terminals via radio interface and forwards them to the access control device through standardized protocols, enabling mobile support without modifying the original access control device.
2Adaptability or versatility
If new hardware is installed to support mobile authentication, then the functionality for mobile access control is improved, but the cost and installation complexity increase
Solution Approach 1:
The extended reading module is designed with universal interfaces that support multiple communication protocols (Wiegand, UART, TCP/IP) and can integrate with various access control devices from different manufacturers. This multi-functionality allows a single module to work across different systems, reducing overall cost and installation complexity.
Solution Approach 2:
By positioning the extended reading module as an intermediary that connects to existing access control devices through standard interfaces, the system avoids the need to replace or extensively modify existing hardware. The module can be added to existing installations with minimal disruption, reducing both cost and installation complexity.
3Adaptability or versatility
If existing access control devices are modified to integrate radio interfaces, then the integration of mobile terminals is improved, but the reliability and robustness in noisy environments may deteriorate
Solution Approach 1:
The radio interface functionality is completely separated from the access control device and implemented in the extended reading module. This segmentation ensures that the original access control device, which is designed for robust operation in noisy environments, remains unmodified and maintains its reliability, while the extended module handles mobile terminal communications.
Solution Approach 2:
The extended reading module serves as an intermediary that isolates the access control system from potential interference introduced by radio interface operations. It processes mobile terminal communications and translates them into standardized formats suitable for the access control device, protecting the original system's reliability while enabling mobile integration.
