Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical RFID badges are used for access control, then existing infrastructure can be utilized, but security is compromised due to copying and sniffing vulnerabilities
Solution Approach 1:
The patent creates a virtual copy of the RFID badge functionality within a mobile device. The emulator captures authentication data from the physical badge and recreates it as a software-based virtual badge, eliminating the need for physical plastic cards while maintaining access control functionality. This virtual copy cannot be physically copied or sniffered since it exists as encrypted software data.
Solution Approach 2:
The patent replaces the mechanical physical badge system with a wireless electronic system. Instead of using physical RFID cards that can be lost or copied, the system uses a mobile device with an emulator that communicates wirelessly with access control readers. This substitution eliminates physical media vulnerabilities while maintaining the same access control function.
2Ease of operation
If physical badges are used, then access control function is provided, but user-friendliness is reduced due to bulkiness and loss risk
Solution Approach 1:
The patent extracts the badge functionality from its physical form and relocates it to a mobile device. The emulator removes the physical badge component entirely, replacing it with a software application that performs the same authentication function. Users no longer need to carry, manage, or protect physical plastic cards, significantly improving user-friendliness.
3Ease of manufacture
If existing card reader infrastructure is retained, then cost is reduced, but system functionality and security features cannot be upgraded
Solution Approach 1:
The patent creates a universal emulator system that can interface with existing access control readers while enabling new functionality. The mobile device-based emulator serves multiple purposes: it provides touchless authentication, stores virtual badges, manages access control credentials, and can be updated with new security features without requiring hardware changes to the reader infrastructure.
4Reliability
If complete redesign of card readers is implemented, then security and functionality are improved, but implementation cost and complexity increase significantly
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the access control system. The emulator application on the mobile device acts as a mediator that translates between modern touchless authentication methods and legacy RFID reader infrastructure. This intermediary layer enables security improvements without requiring direct modification of the existing reader hardware or complex system-wide redesign.
