Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is encrypted and transmitted through a server, then security is improved, but the system becomes cumbersome and anonymous retrieval is impossible
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that mediates between data providers and data requesters. The blockchain network acts as a decentralized mediator that enables anonymous data retrieval through cryptographic proofs and smart contracts, eliminating the need for centralized server authentication while maintaining security.
Solution Approach 2:
The patent replaces the traditional mechanical authentication system (usernames, passwords, server-based verification) with a cryptographic system based on public-key infrastructure and blockchain consensus mechanisms. This substitution enables anonymous yet secure data retrieval through cryptographic proofs rather than identity verification.
2Ease of operation
If a centralized server manages data storage and transmission, then data access is controlled, but security and efficiency are reduced
Solution Approach 1:
The patent segments the centralized server system into multiple decentralized nodes distributed across a blockchain network. Each node maintains a copy of the data ledger and can independently verify and process data access requests, eliminating the single point of failure and security vulnerability inherent in centralized systems.
Solution Approach 2:
The patent implements self-service through smart contracts that automatically execute data access control logic. The system autonomously verifies requester credentials, manages permissions, and transfers data without requiring manual server intervention, thereby maintaining controlled access while improving security and efficiency.
3Reliability
If traditional encryption methods are used, then data confidentiality is protected, but the system lacks decentralization and efficiency
Solution Approach 1:
The patent creates a universal blockchain-based platform that supports multiple data trading models, permission schemes, and cryptographic protocols within a single decentralized system. This multi-functional platform enables various forms of anonymous data exchange while maintaining confidentiality through integrated encryption and smart contract mechanisms.
Solution Approach 2:
The patent changes the fundamental parameters of the data exchange system by transitioning from centralized control to decentralized consensus, and from identity-based authentication to cryptographic proof-based access. These parameter changes enable anonymous yet secure data trading while maintaining confidentiality through advanced cryptographic techniques.

AI summary
A network node for a field device data network, which receives first field device data, store, the first field device data in data blocks, receives a data block request including a public key and digital monetary data, checks the digital monetary data, and if the check is successful, answers the data block request by encrypting the requested data block using the public key and transmitting the data block encrypted using the public key.
