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 between edge devices and cloud infrastructure. IoT devices perform local data processing and filtering at the edge, transmitting only essential or processed data to the cloud. This segmentation reduces network bandwidth consumption while maintaining data processing capability, as the edge device handles preliminary processing locally before cloud transmission.
2Loss of time
If IoT devices operate autonomously at the edge, then response time is improved and bandwidth requirements are reduced, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring smart contracts and autonomous decision-making protocols in IoT devices before deployment. This allows devices to execute pre-programmed responses and local processing without real-time cloud intervention, reducing response time while the initial complexity is managed through standardized pre-deployment configuration processes.
3Reliability
If blockchain technology is integrated into IoT devices for secure communication, then data security is improved, but device complexity and computational requirements increase
Solution Approach 1:
The patent introduces a lightweight blockchain intermediary layer that mediates between IoT devices and the cloud. Instead of implementing full blockchain functionality in resource-constrained devices, a simplified blockchain protocol acts as an intermediary, providing security and trust verification with reduced computational overhead. This intermediary handles complex cryptographic operations while maintaining device simplicity.
