Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If key cards and card readers are used for access control, then user access authorization is improved, but device complexity and maintenance overhead increase
Solution Approach 1:
The patent replaces the mechanical key card system with a wireless communication system using mobile devices. The mobile device's wireless transceiver communicates with access points to authenticate users and control elevator access, eliminating the need for physical key cards and card readers while maintaining access control functionality.
Solution Approach 2:
The patent introduces an authentication server as an intermediary between the mobile device and the elevator control system. The server receives authentication requests, verifies user credentials, and provides authorization information to the elevator controller, centralizing the access control logic and reducing complexity at the elevator level.
2Reliability
If physical guarding personnel are deployed, then security is improved, but operational cost and time consumption increase
Solution Approach 1:
The patent implements a self-service access control system where users authenticate themselves using their mobile devices without requiring human intervention. The system automatically verifies credentials, authorizes access, and controls elevator operation, eliminating the need for guarding personnel while maintaining security.
Solution Approach 2:
The patent incorporates real-time feedback mechanisms where the authentication server continuously monitors authentication status and communicates authorization information to the elevator controller. The system provides immediate feedback on access decisions, enabling automatic security enforcement without human delay.
3Ease of operation
If wireless authentication is implemented, then ease of operation is improved, but measurement precision and location tracking accuracy are challenged
Solution Approach 1:
The patent divides the building into multiple zones with access points strategically positioned to detect mobile devices. By segmenting the detection area into discrete zones with known locations, the system can determine user position based on which access point detects the device, providing sufficient location precision for access control decisions.
