Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID cards are used for building access, then user convenience is improved, but security reliability deteriorates due to loss, theft, or forgetting of cards
Solution Approach 1:
The patent replaces the physical RFID card with a virtual access credential stored in the mobile device's memory. The access credential is copied from the server to the mobile device, eliminating the need for physical cards while maintaining convenient access. This resolves the contradiction by removing the physical object that can be lost or stolen, while preserving the ease of operation through mobile device usage.
Solution Approach 2:
The patent substitutes the mechanical RFID card system with an electronic/mobile-based authentication system. The physical card reader mechanism is replaced with a mobile device that communicates with the controller via Bluetooth or other wireless interfaces. This substitution eliminates the physical card that can be lost or stolen, improving security reliability while maintaining user convenience through the ubiquity of mobile devices.
2Adaptability or versatility
If wireless access control systems with remote access devices are implemented, then access flexibility is improved, but security features deteriorate due to lack of password protection during unlock operations
Solution Approach 1:
The patent merges multiple authentication methods into a single unified system. The mobile device simultaneously provides proximity detection (replacing remote access devices) and password/biometric authentication capabilities. The controller verifies both the presence of the mobile device and the correctness of the password or biometric data before granting access. This combination maintains access flexibility while significantly improving security features.
Solution Approach 2:
The patent introduces the mobile device as an intermediary between the user and the access control system. Instead of direct remote access or simple card reading, the mobile device acts as a mediator that requires both proximity (via Bluetooth/wireless communication) and authentication (via password or biometric verification). This intermediary layer adds security while maintaining flexibility in access methods.
3Device complexity
If fixed access control systems with predetermined access times are used, then system simplicity is improved, but adaptability deteriorates as user accessibility cannot be updated in real time
Solution Approach 1:
The patent transforms the static, predetermined access control system into a dynamic system where access credentials and permissions can be updated in real time. The server can remotely issue, revoke, or modify access credentials in the mobile device without requiring system reconfiguration or hardware changes. This dynamic capability allows real-time accessibility updates while maintaining relative system simplicity through centralized server management.
Solution Approach 2:
The patent creates a universal access control system where a single mobile device can serve multiple functions: storing access credentials, providing authentication, enabling real-time updates, and supporting various access methods (password, biometric, proximity). The server provides universal management capabilities for all users and access points. This multi-functionality achieves real-time adaptability without proportionally increasing system complexity.
4Ease of manufacture
If traditional lock systems or digital lock systems are applied, then installation simplicity is improved, but security effectiveness deteriorates as buildings are not perfectly secured
Solution Approach 1:
The patent replaces traditional mechanical lock systems and basic digital lock systems with an intelligent access control system that uses mobile devices for authentication. The physical key or simple digital code is replaced with a mobile-based authentication system that includes password verification, biometric authentication, and encrypted communication. This substitution maintains installation simplicity through wireless communication while dramatically improving security effectiveness through multiple authentication layers and real-time credential management.

AI summary
An access control system is described and includes a server, a controller for regulating the accessibility of an entrance, and a mobile device having an application for user to trigger an access authentication process, means for collecting biometric information of the user, and a BLUETOOTH module to establish a BLUETOOTH communication link between the mobile device and the controller. The controller includes a communication module for connecting the controller to the server and mobile device for receiving updates on user access credentials, an access module for activating/deactivating a barrier of entrance, and a microprocessor for verifying the received user access credentials, generating an door execution command, and uploading the entrance status to the server.
