Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized gate access control system is implemented, then access management capability is improved, but communication latency and data storage redundancy increase
Solution Approach 1:
The system segments access control decisions by implementing local unit computers at each gate that can independently verify access codes against centrally stored credentials. This allows local access decisions without constant central communication, reducing latency while maintaining centralized management capability.
Solution Approach 2:
Access codes and credentials are pre-loaded into local gate units from the central system. This preliminary action enables local units to make immediate access decisions without real-time communication with the central office, eliminating communication latency for routine access operations.
2Speed
If local units store access codes in memory, then access speed is improved, but data storage redundancy increases
Solution Approach 1:
The system implements local quality by storing complete access code databases in every local gate unit memory. This ensures that each local unit has the capability to independently verify any access code without needing to query the central system, achieving fast local access decisions while accepting the redundancy of duplicated data storage across multiple locations.
3Stability of the object's composition
If centralized control is maintained, then system coordination is improved, but system complexity increases
Solution Approach 1:
The system segments control functions between the central office and local gate units. The central office handles high-level management tasks like adding/removing access codes and monitoring system status, while local units handle routine access verification. This segmentation maintains centralized coordination while simplifying the operational complexity at each level.
Solution Approach 2:
Local gate units are designed to autonomously verify access codes against their stored credentials and control gate operation without requiring central office intervention for each access event. This self-service capability reduces the coordination burden on the central system while maintaining overall system unity through shared credential databases.
