Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wireless data transfer is implemented in drug delivery devices, then data synchronization and compliance monitoring are improved, but security risks and unauthorized access increase
Solution Approach 1:
The patent implements preliminary pairing between the drug delivery device and external device before data transfer. The pairing process establishes encryption keys and security credentials in advance, ensuring that only authorized devices can access transmitted data. This preliminary authentication prevents unauthorized access while enabling secure data synchronization.
Solution Approach 2:
The patent introduces an intermediary pairing mechanism that mediates between the drug delivery device and external devices. The pairing system acts as a security intermediary, verifying device identities and establishing secure communication channels before allowing data transfer, thus protecting against unauthorized access.
2Object-affected harmful factors
If complex security protocols are implemented for wireless pairing, then data security is improved, but ease of operation and user-friendliness deteriorate
Solution Approach 1:
The patent implements self-service pairing where the drug delivery device and external device automatically perform pairing operations without requiring complex user input. The devices autonomously exchange cryptographic information and establish secure connections, making the security process transparent and user-friendly while maintaining high security standards.
Solution Approach 2:
The patent combines multiple security functions into a unified pairing process. Authentication, key exchange, and device identification are merged into a single automated pairing operation, simplifying the user experience while implementing comprehensive security measures.
3Object-affected harmful factors
If secure pairing protocols are implemented, then data transmission security is improved, but device complexity and implementation costs increase
Solution Approach 1:
The patent implements a universal pairing mechanism that can be applied to various drug delivery devices and external devices using standard wireless communication protocols. The pairing system is designed to be device-agnostic and protocol-independent, reducing implementation complexity while maintaining security across different device types.
Solution Approach 2:
The patent replaces complex mechanical or manual security mechanisms with electronic and cryptographic solutions. The pairing process uses software-based authentication and key exchange protocols, eliminating the need for physical security elements and reducing overall system complexity while enhancing security.
