Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital vehicle key authentication is implemented using only mobile terminal connection, then ease of operation is improved, but security is worsened due to unauthorized access risks when device is lost
Solution Approach 1:
The authentication process is segmented into multiple independent verification stages: first verifying the mobile terminal connection, then separately verifying trajectory conditions, and finally combining both results. This segmentation allows each verification layer to focus on specific security aspects without compromising operational convenience.
Solution Approach 2:
The trajectory verification serves as an intermediary layer between the mobile terminal connection and the final authentication decision. By introducing this intermediate verification mechanism, the system can assess whether the mobile device has followed a reasonable path to the vehicle, adding security without directly impacting the ease of operation.
2Reliability
If additional hardware authentication methods like fingerprint or face recognition are added, then security is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces physical hardware authentication mechanisms (fingerprint sensors, face recognition cameras) with a software-based trajectory verification system. By substituting mechanical/hardware verification with computational analysis of movement patterns, the system achieves enhanced security without increasing device complexity or requiring additional hardware components.
Solution Approach 2:
The system utilizes data already being collected by the mobile terminal (location information, movement trajectory) to perform authentication. Instead of requiring additional hardware inputs, the system makes the authentication decision based on self-generated data from the mobile device's normal operation, avoiding the need for extra hardware while maintaining security.
3Reliability
If trajectory verification is added to authentication process, then security is improved, but measurement precision requirements increase
Solution Approach 1:
The system does not require perfect or excessive precision in trajectory measurement. Instead, it uses partial trajectory information (basic movement path from location data) to make authentication decisions. The verification accepts approximate trajectory patterns rather than demanding exact precision, thereby improving security without imposing unrealistic measurement precision requirements.
