Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor electronics unit allows communication with any user terminal, then ease of operation is improved, but reliability deteriorates due to unauthorized apps providing inaccurate glucose values
Solution Approach 1:
The sensor electronics unit performs preliminary verification of the security key before establishing communication. The verification process checks whether the received second security key matches the pre-stored first security key associated with authorized apps. This preliminary action ensures that only authorized applications can establish communication, preventing unauthorized apps from providing inaccurate glucose values while maintaining ease of operation for legitimate users.
2Reliability
If the sensor electronics unit implements security key verification, then reliability is improved, but device complexity increases due to additional verification steps
Solution Approach 1:
The verification functionality is extracted as a separate, dedicated process within the sensor electronics unit. The unit receives the second security key from the user terminal and performs verification by comparing it against the pre-stored first security key. This extracted verification mechanism operates independently, providing reliable security checks without significantly increasing the overall device complexity. The separation allows the verification logic to be implemented as a distinct module, making the system more manageable and maintainable.
3Adaptability or versatility
If the sensor electronics unit stores multiple security keys for third-party apps, then adaptability is improved, but security risk increases
Solution Approach 1:
The sensor electronics unit implements a feedback mechanism where each stored security key is associated with verified authorized third-party apps. When a user terminal attempts to connect, the unit checks the provided second security key against the pre-stored first security keys in a whitelist. This feedback loop ensures that only apps with valid security keys can establish communication. The system dynamically responds to connection attempts by verifying credentials, thereby maintaining security while enabling compatibility with multiple authorized third-party applications.
