Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decentralized physical storage information management is used, then information security is improved, but information retrieval efficiency and multi-functional application capability deteriorate
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between decentralized storage and information retrieval applications. The blockchain serves as a mediator that coordinates distributed storage nodes, enabling efficient information retrieval through consensus mechanisms and smart contracts while maintaining the security benefits of decentralized storage. This resolves the contradiction by providing a structured intermediary framework that optimizes both security and efficiency.
Solution Approach 2:
The patent implements a universal blockchain-based information management system that can handle multiple functions including storage, retrieval, verification, and application of device state information. The blockchain platform provides multi-functional capabilities through smart contracts and decentralized applications, allowing the same infrastructure to serve diverse purposes without compromising security or efficiency.
2Productivity
If database or cloud storage-based information management is used, then information retrieval efficiency is improved, but information security deteriorates
Solution Approach 1:
The patent segments the information management system into multiple independent components: decentralized storage nodes, blockchain consensus layer, smart contract execution environment, and application interfaces. This segmentation allows the system to achieve efficient retrieval through distributed query processing while maintaining security through cryptographic verification and decentralized architecture, resolving the contradiction between efficiency and security.
Solution Approach 2:
The patent creates a composite information management system that combines the advantages of centralized database efficiency with decentralized storage security. The system integrates blockchain technology with distributed file storage, creating a hybrid architecture that leverages the speed of centralized processing and the security of decentralized storage, thus resolving the contradiction between retrieval efficiency and information security.
3Productivity
If device state information is stored in centralized databases, then information retrieval and application efficiency is improved, but security against abnormal information modification deteriorates
Solution Approach 1:
The patent implements feedback mechanisms through blockchain verification and smart contract validation that continuously monitor and verify device state information. The system provides feedback loops where stored information is periodically checked against blockchain records, enabling detection and prevention of abnormal modifications while maintaining efficient retrieval and application capabilities.
Solution Approach 2:
The patent applies preliminary anti-action by using cryptographic hashing and blockchain immutability to prevent abnormal information modification before it can occur. The system establishes secure storage structures in advance that make tampering with device state information extremely difficult, thereby protecting against harmful factors while maintaining efficient information management operations.

AI summary
The specification provides a method and apparatus for managing a measurement device based on a blockchain, which is applied to node devices in a blockchain network. The method comprises: obtaining device state data of the measurement device at various stages in the life cycle of the measurement device; constructing a target transaction based on the obtained device state data, and then sending the target transaction to other node devices in the blockchain network to perform consensus processing on the target transaction; and storing, when a consensus of the target transaction is reached, the target transaction into a distributed ledger of the blockchain network, wherein the target transaction stored in the distributed ledger of the blockchain network is used for life cycle management of the measurement device.
