Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is performed using traditional methods between devices or servers, then data exchange can be achieved, but it requires significant time and effort for updates and specifications definition
Solution Approach 1:
The patent uses blockchain to create immutable copies of data transmission records distributed across multiple nodes. Each transaction is copied and verified across the network, eliminating the need for centralized update mechanisms and reducing time spent on maintaining data consistency between devices and servers.
Solution Approach 2:
The smart contract mechanism performs preliminary verification and validation of data transmission parameters before actual transmission occurs. This pre-verification process automates specification checking and reduces the time required for post-transmission updates and corrections.
2Reliability
If traditional data transmission methods are used, then data exchange occurs, but it is difficult to prove whether the data is reliable and track transmission history
Solution Approach 1:
The blockchain system provides continuous feedback through the distributed ledger that records every transaction immutably. Each node receives feedback about the state of the ledger and can verify transmission history at any point, ensuring data reliability and complete auditability without information loss.
Solution Approach 2:
The blockchain acts as a neutral intermediary that mediates between transmitting and receiving devices. It provides an independent verification layer that proves data reliability through cryptographic validation and maintains complete transmission history records that are accessible to all authorized participants.
3Reliability
If blockchain ledger is used to store data transmission records, then data reliability and tracking are improved, but device complexity increases
Solution Approach 1:
The patent segments the blockchain implementation into distinct functional modules: smart contract execution, transaction verification, ledger maintenance, and data transmission. This segmentation allows each component to be optimized independently and simplifies the overall system architecture, reducing device complexity while maintaining reliability benefits.

AI summary
An electronic device is provided. The electronic device includes a communication circuit, a memory configured to store a partial ledger including a part of a full ledger for a blockchain network or the full ledger, and a processor. The processor is configured to generate a first transaction using a smart contract including shared data of the electronic device and information on an external user to receive the shared data, request to transmit the first transaction to the blockchain network, verify the first transaction using a node creating at least one block corresponding to each of at least one transaction, transmit the first transaction to the blockchain network, create a first block corresponding to the first transaction, verify a second transaction based on receiving a second transaction, execute the smart contract, and to create a second block corresponding to the second transaction.
