Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted without anonymization to assistance devices, then personalized traffic assistance can be provided, but privacy protection is compromised
Solution Approach 1:
The patent applies local quality by differentiating data processing based on the recipient assistance device. Configuration information stored in the relay device specifies which assistance devices receive anonymized data and which receive non-anonymized data. This allows personalized assistance for authorized devices while protecting privacy for unauthorized devices, creating different data quality characteristics for different recipients.
2Object-affected harmful factors
If all data is anonymized before transmission, then privacy protection is improved, but personalized traffic assistance cannot be provided
Solution Approach 1:
The patent implements dynamics by making the anonymization status configurable rather than fixed. The relay device stores configuration information that can be updated to change which assistance devices receive anonymized versus non-anonymized data. This dynamic approach allows the system to adapt privacy levels based on trust relationships and assistance requirements without redesigning the entire system.
3Object-affected harmful factors
If configuration information is stored for each assistance device, then privacy control is improved, but device complexity increases
Solution Approach 1:
The patent applies copying by using configuration information that can be stored and referenced multiple times. Instead of creating complex real-time decision logic, the system stores predefined configuration data specifying anonymization requirements for each assistance device. The relay device simply copies and applies the appropriate configuration based on the target device, reducing computational complexity while maintaining privacy control.
