Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional software encryption algorithms are used for device authentication and data communication, then security protection is provided, but device resource requirements increase and complexity rises
Solution Approach 1:
The patent introduces a border gateway as an intermediary component between sensing devices and the cloud platform. The gateway implements the complex encryption and authentication operations, while sensing devices use simpler verification protocols. This mediator approach allows strong security without burdening resource-constrained IoT devices with complex cryptographic operations.
Solution Approach 2:
The patent replaces traditional software-based encryption mechanisms with a hardware security module (HSM) or secure element embedded in the border gateway. This hardware substitution provides equivalent or superior security with lower computational overhead and better resistance to attacks, while reducing the software complexity burden on the system.
2Reliability
If hardware encryption means such as security encryption chips are added to the border gateway, then device authentication and data communication security are improved, but device overheads and electric consumption increase
Solution Approach 1:
The patent segments the security functionality into two parts: a hardware security module for key generation and storage (low-power operations) and software-based cryptographic operations for actual data processing (higher-power operations). By separating these functions and executing them at appropriate times, the system achieves strong authentication security while minimizing overall power consumption during normal operation.
3Ease of operation
If massive sensing data is stored in a few central nodes, then data collection is simplified, but data security and backup capability are compromised
Solution Approach 1:
The patent transitions from a single-dimension centralized storage model to a multi-dimensional distributed storage architecture using blockchain technology. Data is replicated across multiple nodes in the network, creating redundancy in the spatial dimension. This distributed approach maintains ease of data collection through standardized interfaces while dramatically improving security and backup capabilities through decentralization.
Solution Approach 2:
The patent changes the fundamental parameter of data storage architecture from centralized to distributed. By implementing blockchain-based distributed ledger technology, the system transforms how data is stored, secured, and accessed. This parameter change enables both simplified data collection through standardized protocols and enhanced security through cryptographic distribution across multiple nodes.
4Reliability
If blockchain technology is implemented for data storage and authentication, then data integrity and security are improved, but device resource requirements and system complexity increase
Solution Approach 1:
The patent segments the blockchain system into distinct functional layers: a consensus layer for maintaining data integrity (implemented in the border gateway), a data storage layer for secure record-keeping (distributed across nodes), and an application layer for sensing device interactions. This segmentation allows the sensing devices to interact with a simplified interface while the complex blockchain mechanisms operate transparently in the background at the gateway level.
Solution Approach 2:
The border gateway acts as an intermediary that shields sensing devices from blockchain complexity. The gateway handles all blockchain-specific operations including transaction validation, consensus participation, and ledger maintenance, while presenting a simple, standardized interface to sensing devices. This mediator approach enables data integrity through blockchain without exposing device complexity to the IoT endpoints.

AI summary
The present disclosure discloses an electric border gateway device which adopts the blockchain technology to implement communication authentication and data transmission encryption at the gateway. As a device for sinking and processing local information, the border gateway device may build not only a local blockchain network with a variety of local electric sensing terminal devices, but also a regional blockchain network with other border gateways and electric management platforms. As a critical node of these two types of blockchain, the border gateway may enable the authentication of identity legality between electric sensing terminal devices, the critical data storage in the blockchain ledger, the deployment and implementation of blockchain transaction by control and coordinated functions, and the safe and reliable data interaction. The present disclosure also discloses a method for chaining and storage of sensing data based on the electric border gateway device.
