Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If points are distributed over a network in data form to enable easy access and usage, then ease of operation is improved, but security and reliability deteriorate due to vulnerabilities to illegal copying and forgery
Solution Approach 1:
The patent replaces traditional centralized database management with a blockchain-based distributed ledger system. This substitution transforms the mechanical data storage and verification process into a decentralized cryptographic system where transactions are secured through hash functions and public-private key pairs, eliminating the security vulnerabilities of centralized systems while maintaining ease of access.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary between point distributors and users. This intermediary layer provides transparent, immutable transaction records that verify point exchanges without requiring trusted central authorities, thus enhancing security while preserving operational simplicity through automated smart contract execution.
2Device complexity
If traditional centralized systems are used to manage point transactions, then device complexity is reduced, but security and prevention of duplicate issuance deteriorate
Solution Approach 1:
The patent segments the centralized management system into distributed nodes across a blockchain network. Each node independently validates and records transactions, eliminating single points of failure and duplicate issuance risks while maintaining systematic simplicity through standardized cryptographic protocols and automated consensus mechanisms.
3Reliability
If cryptographic technologies are implemented to secure point transactions, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service cryptographic verification through automated smart contracts and digital signatures. The system autonomously validates transactions using public-private key pairs and hash functions without requiring manual intervention or complex verification procedures, thus enhancing security while masking the underlying cryptographic complexity from users.

AI summary
A method of registering a point distributor and an exchange rate for a united point service is provided. The method includes steps of: a system managing server (a) verifying a registration transaction TrxA or a confirmation transaction TrxB if (i) a condition that the TrxA having a public key of a point managing server, and a first XEA, an exchange rate of a point A of a point distributor to the united point, is acquired from a point distributing server, or (ii) a condition that the TrxB having a public key of the point distributing server and a second XEA is acquired from the point managing server, is satisfied; and (b) if the TrxA or the TrxB is valid, (i) recording it on a blockchain database, (ii) initializing a balance database by updating a balance of the point distributor, and (iii) acquiring a transaction ID of the TrxA, the TrxB.
