Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encryption methods are used, then data security is improved, but user authentication complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-installing cryptographic references (keys and algorithms) on wearable devices during manufacturing. This allows the device to automatically perform encryption and decryption operations without requiring users to manually configure authentication credentials, thereby maintaining data security while eliminating authentication complexity for users.
Solution Approach 2:
The wearable device performs self-service by autonomously managing cryptographic operations using pre-configured references. The device automatically encrypts data before transmission and can decrypt received data without user intervention, making the security mechanism transparent and effortless for users while ensuring reliable data protection.
2Ease of operation
If factory-installed cryptographic references are used, then ease of operation is improved, but cryptographic flexibility decreases
Solution Approach 1:
The patent implements universality by designing the wearable device to support multiple cryptographic algorithms through pre-installed references. The device can selectively apply different encryption algorithms (e.g., AES, RSA, ECC) based on the specific data type and security requirements, thereby maintaining operational simplicity while preserving cryptographic flexibility and adaptability.
3Device complexity
If fixed cryptographic algorithms are used, then device complexity is reduced, but security reliability decreases due to potential algorithm compromise
Solution Approach 1:
The patent applies dynamics by enabling the wearable device to dynamically select and switch between multiple pre-installed cryptographic algorithms. When a security vulnerability is identified in one algorithm, the system can automatically transition to an alternative algorithm without requiring hardware changes or complex reconfiguration, thus maintaining low device complexity while ensuring ongoing security reliability.
