Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control systems use card readers or basic cameras, then the system is simple to operate, but the system lacks the ability to detect duress, prevent tailgating, and provide second factor authentication
Solution Approach 1:
The patent combines facial recognition technology with skeletal tracking technology into a unified access control system. The facial recognizer processes facial images to identify users, while the skeletal tracker analyzes body movements to detect duress gestures. These two recognition systems are merged to work together, providing both authentication and security monitoring capabilities simultaneously, thereby enhancing reliability without proportionally increasing complexity.
Solution Approach 2:
The access control system is designed to perform multiple functions: facial recognition for user identification, skeletal tracking for duress detection, tailgating prevention through multiple subject detection, and second factor authentication. By making the system universal and multi-functional, it addresses multiple security concerns within a single integrated platform, improving reliability while managing complexity through consolidation.
2Reliability
If the system implements multiple security features (duress detection, tailgating prevention, second factor authentication), then security reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system employs frictionless access control where the authentication process occurs automatically without requiring active user participation. As users naturally approach the access point, the facial recognizer and skeletal tracker continuously process images to verify identity and detect duress. The system self-Service completes authentication in the background, maintaining ease of operation while implementing multiple security features.
Solution Approach 2:
The system performs preliminary authentication and security checks before the user actually needs to access the secured area. Facial recognition and skeletal tracking occur as users approach the access point, so that by the time the user reaches the door, authentication is already complete. This preliminary action ensures security requirements are met without adding steps to the user's操作流程.
3Productivity
If the system uses facial recognition with skeletal tracking for frictionless access, then productivity is improved through automated authentication, but the difficulty of detecting and measuring worsens due to complex gesture recognition requirements
Solution Approach 1:
The patent replaces complex mechanical or manual security verification methods with optical and computational systems. Instead of requiring manual security checks or physical tokens, the system uses cameras to capture images and computational algorithms (facial recognition and skeletal tracking) to automatically verify identity and detect gestures. This substitution maintains high productivity while managing detection complexity through software-based solutions.
Solution Approach 2:
The system introduces an intermediary computational layer between the camera input and the security decision. The skeletal tracker serves as an intermediary that processes raw image data, extracts skeletal information, recognizes gestures, and translates them into security-relevant signals. This intermediary approach enables automated duress detection while maintaining productivity by handling complexity in the computational layer rather than requiring direct human analysis.
4Measurement precision
If the system implements real-time facial recognition and skeletal tracking, then measurement precision is improved for user identification, but the use of energy worsens due to continuous processing requirements
Solution Approach 1:
Instead of continuous processing, the system uses periodic action by triggering facial recognition and skeletal tracking based on detection events. The camera captures images periodically or when motion is detected, and processing is initiated based on these triggers rather than running continuously. This approach maintains measurement precision for user identification while reducing energy consumption by processing only when necessary.

AI summary
An access control system can include a camera that detects an image regarding a subject, a database maintaining information, a facial recognizer that receives the image and identifies a facial feature of the subject based on the received image and the facial information maintained by the database, and a processor to alert security or another user when an authorized user accessing an area of a building is under duress, when an unauthorized user is accessing an area of a building by tailgating after an authorized user, when an authorized user has not provided two-factor authentication, or when an authorized user is in a particular area of the building.
