Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If IoT devices transmit all generated data to the cloud, then data processing capability is improved, but network bandwidth consumption increases and latency increases
Solution Approach 1:
The patent segments data processing functions between edge devices (IoT devices) and cloud infrastructure. Edge computing nodes process and filter data locally before transmitting only essential information to the cloud, reducing network bandwidth consumption while maintaining data processing capability.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between IoT devices and the cloud. The blockchain network enables decentralized data verification and processing, allowing devices to validate data integrity peer-to-peer without constant cloud communication, thereby reducing latency and bandwidth usage.
2Loss of information
If centralized cloud management is used for IoT devices, then data processing capability is improved, but security risks from hacked devices increase
Solution Approach 1:
The patent segments the centralized cloud management into a decentralized blockchain network. Each node in the network maintains its own copy of the ledger and can independently verify transactions, eliminating the single point of failure represented by centralized cloud servers and reducing security risks from hacks.
Solution Approach 2:
The patent implements cryptographic verification and consensus mechanisms in the blockchain system that provide continuous feedback on data integrity and device authenticity. This allows the network to detect and reject fraudulent or compromised devices automatically, enhancing security without sacrificing data processing capability.
3Reliability
If blockchain technology is integrated into IoT devices, then data security is improved, but device complexity increases
Solution Approach 1:
The patent extracts the most computationally intensive blockchain operations (such as full ledger validation and complex cryptographic operations) and relocates them to dedicated blockchain nodes or cloud services. IoT devices only perform lightweight operations like generating cryptographic signatures and verifying basic consensus, significantly reducing device complexity while maintaining data security.
