Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional badge-based identification is used, then access control is simple to implement, but security is compromised due to easy fabrication of fraudulent badges

Engineering Contradiction:
ImprovesecurityVSAvoidaccess control system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical badge-based identification with a biometric authentication system using facial recognition technology. The system captures facial images, extracts biometric features, and compares them against stored templates to verify identity, eliminating the need for physical badges that can be forged.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital copy of the user's biometric data (facial features) and stores it as a template in a database. This digital biometric template serves as the authentication credential, replacing the physical badge while providing superior security against fraud.

Inventive Principle:
Principle #26Copying

2Productivity

If manual badge checking is performed, then system complexity is low, but time consumption increases causing lengthy queues

Engineering Contradiction:
Improveaccess processing speedVSAvoidaccess control system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables self-service authentication where users simply present their face to the camera for automatic verification. The biometric system independently performs image capture, feature extraction, template matching, and authentication decisions without requiring manual badge checking by security personnel.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual badge checking operations with automated biometric verification using facial recognition technology. The system automatically captures facial images, processes biometric data, and makes authentication decisions, eliminating the need for human operators to manually verify physical badges.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If people are kept close together in queues for access control, then space utilization is efficient, but health risk increases due to pathogen transmission

Engineering Contradiction:
Improvepathogen transmission riskVSAvoidqueue space utilization
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The system performs biometric verification before users enter the facility, allowing for pre-screening and contactless authentication. This preliminary verification eliminates the need for close-contact queueing at access points, as users can be authenticated from a distance using facial recognition technology.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for enhanced access control is provided that includes the steps of displaying buttons, by an electronic device, where each button corresponds to a different service. Moreover, the method includes receiving, by the electronic device, input regarding a selected service, transmitting at least one credential for the selected service to a computer, and capturing, by a camera in communication with the computer, facial image data of a user. The method also includes determining whether the facial image data was taken of a live person. In response to determining the facial image data was taken of a live person, a verification transaction is conducted based on the at least one credential and facial image data. In response to verifying the identity of the user as true, the user is granted access to the selected service.
