Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning integrity control functionality is implemented, then positioning reliability is improved, but device and network complexity increases
Solution Approach 1:
The patent introduces an intermediary integrity verification mechanism using CRC checks and encryption/decryption operations as intermediate steps between positioning data transmission and utilization. These intermediary verification steps ensure positioning reliability without requiring fundamental changes to the core positioning architecture, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The patent applies preliminary integrity verification actions by performing CRC checks and encryption/decryption operations on positioning data before the data is utilized for positioning calculations. This preliminary validation ensures that integrity issues are detected early in the data flow, preventing propagation of errors while maintaining a structured approach to complexity management.
2Reliability
If integrity verification mechanisms are added, then positioning data integrity is improved, but signaling overhead increases
Solution Approach 1:
The patent merges integrity verification functions (CRC checks, encryption/decryption) with existing positioning data transmission protocols. By combining these verification mechanisms into the existing signaling framework rather than creating separate dedicated channels, the patent improves data integrity while minimizing the increase in signaling overhead through efficient resource utilization.
3Reliability
If secure transfer mechanisms are implemented, then positioning security is improved, but processing time increases
Solution Approach 1:
The patent performs encryption and decryption operations as preliminary actions before positioning data is transmitted and after reception. By establishing secure encryption/decryption keys and performing these operations in advance and immediately upon reception, the patent ensures positioning security while minimizing the time penalty through efficient key management and optimized cryptographic operations.
