Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If badge-based access control systems are used, then ease of operation is improved, but security reliability deteriorates due to vulnerability to theft, borrowing, counterfeiting, and tailgating
Solution Approach 1:
The patent replaces the mechanical badge-based access control system with a biometric facial recognition system. Instead of using physical cards that can be stolen or copied, the system uses unique facial characteristics to authenticate users, thereby eliminating the security vulnerabilities associated with badge theft and counterfeiting while maintaining ease of access.
Solution Approach 2:
The system creates a digital copy of the user's facial characteristics and stores it in a database. During authentication, the system compares the live facial scan against the stored digital copy to verify identity. This digital copying approach eliminates the need for physical badges that can be copied or stolen.
2Reliability
If biometric verification systems are used, then security reliability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent employs a simplified facial recognition system that uses readily available hardware components such as webcams and standard processors, rather than expensive specialized biometric devices. The system can be implemented using consumer-grade technology that is easily replaceable and cost-effective.
Solution Approach 2:
The system uses a multi-functional approach where a single facial recognition module can serve multiple access control points and integrate with existing building management systems. The same hardware and software platform can be deployed across multiple locations, reducing overall system complexity and cost.
3Reliability
If facial recognition systems are used, then security reliability is improved, but loss of time increases due to enrollment and authentication processing time
Solution Approach 1:
The system performs preliminary enrollment of users' facial characteristics during their first visit, creating a digital facial template that is stored in the database. Subsequent authentication processes then only require comparing the live scan against the pre-stored template, significantly reducing the time required for each access event while maintaining high security standards.
Solution Approach 2:
The patent implements a streamlined authentication process that skips unnecessary verification steps. By using rapid facial recognition algorithms and optimized hardware, the system can authenticate users in a fraction of a second, effectively rushing through the authentication process without compromising security.
4Reliability
If human guards are deployed, then security reliability is improved, but loss of time increases due to manual verification processes
Solution Approach 1:
The facial recognition system enables self-service authentication where users automatically present their faces to the access control system, which then autonomously verifies their identity and controls access. This eliminates the need for manual verification by human guards, significantly reducing both time consumption and operational costs while maintaining or improving security reliability.

AI summary
Systems and methods are provided for controlling access to a building or other restricted physical spaces using at least a facial recognition module. The facial recognition module comprises visible light and infrared detection. In some embodiments the facial recognition module comprises an angled front panel to limit blind spots near an entrance. In some embodiments, a facial recognition module may be mounted on one side of an entry point, and a second module on the opposite side, and together they may be configured to prevent unauthorized entry by blocking the opening of the entry point if an unauthorized person is on either side of the entry point.
