Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical RFID badges are used for access control, then access control functionality is provided, but the system becomes bulky, easily misplaced, and vulnerable to security breaches
Solution Approach 1:
The patent replaces the mechanical physical badge system with a wireless communication system. The mobile device uses Bluetooth Low Energy to communicate with the emulator device, eliminating the need for physical RFID badges. This substitution resolves the contradiction by providing secure access control without the bulk and security vulnerabilities of physical badges, while maintaining ease of operation through wireless interaction.
Solution Approach 2:
The emulator device creates a virtual copy of the physical badge functionality. Instead of using actual physical RFID cards, the system generates and transmits virtual badge signals through the emulator device. This copying approach allows users to access control functionality without carrying physical badges, resolving the contradiction between security reliability and operational convenience.
2Adaptability or versatility
If existing card readers are retrofitted with new functionality, then system capabilities are enhanced, but installation becomes time-consuming and costly
Solution Approach 1:
The emulator device is designed as a universal retrofit solution that can be installed in existing card reader slots without requiring specialized installation infrastructure. The device performs multiple functions including Bluetooth communication, RFID emulation, and access control, allowing a single device to replace and enhance existing reader capabilities. This multi-functionality reduces installation time and cost while enhancing system versatility.
Solution Approach 2:
The emulator device acts as an intermediary between the mobile device and the existing card reader infrastructure. It translates wireless Bluetooth signals from mobile devices into RFID-compatible signals that existing readers can process. This intermediary approach enables functionality enhancement without requiring direct modification of the existing reader hardware, significantly reducing installation time and cost.
3Reliability
If complete redesign of card readers is implemented, then security and functionality are improved, but the cost and complexity of installation increases
Solution Approach 1:
The system is segmented into three independent components: the mobile device, the emulator device, and the existing card reader. This segmentation allows each component to maintain its original functionality while working together to provide enhanced security. The emulator device serves as a bridge that adds security features without requiring redesign of the reader or mobile device, reducing overall system complexity and installation difficulty.
