Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user-related data is collected and processed in cloud-based systems, then adaptability to user environment changes is improved, but data security and privacy protection deteriorate
Solution Approach 1:
The system segments data processing into edge network-based preprocessing and cloud-based analysis. The edge network device group preprocesses user-related data locally, filtering and preparing only necessary information for transmission to the cloud-based device group. This segmentation reduces the amount of sensitive data exposed to cloud systems while maintaining adaptability through localized data handling.
Solution Approach 2:
A blockchain-based data management device acts as an intermediary between the edge network and cloud-based systems. It manages data sharing securely, ensuring privacy protection while enabling necessary data exchange. The blockchain mechanism provides transparent and secure data transmission, resolving the contradiction between data accessibility and security.
2Reliability
If data processing is performed at the edge network, then data security is improved, but computational capability and adaptability deteriorate
Solution Approach 1:
The system divides computational tasks into two segments: edge network-based preprocessing for security-critical operations and cloud-based processing for complex analysis. The edge network device group handles data filtering and preliminary processing securely, while the cloud-based device group performs reinforcement learning and generates control data. This segmentation allows each layer to optimize for its specific function without compromising overall capability.
Solution Approach 2:
The system merges edge network and cloud-based processing capabilities into a unified IoT service framework. The edge network-based device group and cloud-based device group work together, with the former providing secure data preparation and the latter providing advanced computational analysis. This merging enables both security and high computational capability to coexist.
3Reliability
If blockchain is used for data sharing between edge and cloud systems, then data management security is improved, but system complexity increases
Solution Approach 1:
The blockchain-based data management device serves as an intermediary layer that simplifies secure data sharing between edge and cloud systems. It handles the complexity of cryptographic operations, data verification, and secure transmission automatically, allowing the system to achieve high security without requiring complex manual security management at each layer.
