Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic devices lack wireless protocol capabilities (e.g., NFC), then device complexity is reduced, but secure data transmission capability deteriorates
Solution Approach 1:
The patent introduces a secondary device as an intermediary that bridges the gap between devices with and without NFC capabilities. The secondary device receives data from the primary device via wireless connection and handles the secure transmission using NFC, enabling capable devices to provide security without requiring all devices to have the full capability set.
Solution Approach 2:
The system creates a universal solution where devices can function with or without NFC by leveraging the secondary device. The secondary device performs multiple functions including receiving data, verifying credentials, and conducting secure exchanges, making the system adaptable to different device configurations.
2Reliability
If all devices incorporate all wireless protocols and capabilities, then secure data transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the device functionality into two types: primary devices that may lack NFC but have other capabilities, and secondary devices that provide the NFC and security functions. This segmentation allows each device type to be optimized for its specific role rather than requiring all devices to have all capabilities.
Solution Approach 2:
The secondary device acts as an intermediary that concentrates the complex security and NFC functions, allowing primary devices to remain simpler while still achieving secure data transmission when needed.
3Ease of operation
If devices without NFC capabilities attempt secure transmission, then ease of operation is improved, but transmission security deteriorates
Solution Approach 1:
The secondary device serves as a mediator that enables devices without NFC to perform secure transmissions by handling the complex security protocols and NFC communications, providing both ease of operation and transmission security simultaneously.
Solution Approach 2:
The system replaces the mechanical NFC hardware requirement with a software-based solution where the secondary device handles the security functions, allowing devices without physical NFC capabilities to achieve secure transmission through alternative communication methods.
