Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static QR codes are used, then ease of manufacture and operation are improved, but security reliability deteriorates due to unauthorized duplication
Solution Approach 1:
The patent transitions from static QR codes to dynamic QR codes that change over time. The system generates QR codes with time-varying patterns that expire after use, preventing unauthorized duplication while maintaining ease of operation through automated generation and verification processes.
Solution Approach 2:
The system implements a feedback mechanism where the QR code is verified by a server that checks its validity and updates its status. This feedback loop ensures that only valid, unexpired QR codes are accepted, enhancing security while maintaining operational simplicity through automated verification.
2Reliability
If dynamic QR codes are generated with LiDAR environmental mapping, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that handles the complex tasks of QR code generation, environmental mapping verification, and validity checking. This moves the computational complexity from the end-user device to a centralized server, reducing device complexity while maintaining high security through sophisticated verification processes.
Solution Approach 2:
The system replaces traditional mechanical or manual QR code generation methods with AI-based environmental mapping and pattern generation. The LiDAR-based spatial understanding and neural network-based QR code generation automate the process, reducing manual intervention while enhancing security through unique environmental fingerprints.
3Reliability
If AI-based environmental mapping is used for QR code generation, then uniqueness and security are improved, but processing time increases
Solution Approach 1:
The system performs preliminary environmental mapping and stores the spatial data before QR code generation is needed. By pre-processing the environmental data and maintaining it in the system, the actual QR code generation process can quickly reference stored information rather than performing full environmental scans in real-time, reducing processing time while maintaining uniqueness.
