Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized diagnostic systems are used, then data transmission and analysis are simple, but data security and reliability are compromised
Solution Approach 1:
The patent segments the centralized diagnostic system into distributed blockchain nodes, where each node independently stores and validates fault data. This segmentation enhances data security through decentralization while managing complexity through standardized blockchain protocols and smart contracts that automate consensus and data validation processes.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between vehicle diagnostic systems and service centers. This intermediary provides secure, tamper-proof data transmission and storage, enhancing reliability while abstracting away the underlying complexity through standardized interfaces and automated smart contract execution.
2Ease of operation
If diagnostic devices are connected to physical OBD terminals, then fault diagnosis can be performed, but consumers must visit service centers losing convenience
Solution Approach 1:
The patent enables self-service diagnostic capabilities by allowing consumers to access and analyze their own vehicle fault data through mobile applications connected to the blockchain network. Consumers can perform preliminary fault diagnosis, monitor repair histories, and access diagnostic information without physically visiting service centers, thereby improving convenience and reducing time loss.
Solution Approach 2:
The patent implements preliminary fault detection and data collection capabilities that continuously monitor vehicle health parameters and store fault information on the blockchain in real-time. This preliminary action allows consumers to access diagnostic information immediately when needed, eliminating the need to wait at service centers and enabling proactive scheduling of repairs.
3Loss of information
If fault data is transmitted externally, then diagnostic information can be accessed, but information security and data protection are compromised
Solution Approach 1:
The patent transitions fault data storage from traditional external servers to a distributed blockchain network, adding the dimension of decentralization. This dimensional change enables data accessibility through multiple nodes while simultaneously protecting against data leakage through cryptographic security and distributed storage, where no single point of failure or attack exists.
Solution Approach 2:
The patent creates a secure, tamper-proof environment for fault data storage using blockchain's immutable ledger and cryptographic hashing. This inert environment protects data from unauthorized access, modification, or leakage while maintaining accessibility through authorized nodes and smart contracts that control data retrieval according to predefined rules.
4Reliability
If existing diagnostic methods are used, then post-failure diagnosis is possible, but proactive failure prediction is difficult
Solution Approach 1:
The patent implements feedback mechanisms where fault data continuously accumulates on the blockchain, and smart contracts analyze patterns to generate predictive insights. The system provides feedback to consumers about vehicle health status, potential future failures, and recommended maintenance actions, enabling proactive failure prediction while managing analysis complexity through automated algorithms and standardized data structures.
Solution Approach 2:
The patent enables preliminary failure prediction by continuously monitoring vehicle parameters and storing diagnostic data on the blockchain before actual failures occur. The system analyzes historical fault patterns and generates early warnings about potential issues, allowing consumers to take preventive actions before failures happen, thereby improving reliability while using automated analysis to manage complexity.
Data Source
AI summary
A system for managing fault information about vehicles based on blockchain includes a data storage unit configured to store at least one of fault information or a repair history of the vehicles, with interlinked blockchain tokens of vehicle controllers. The system also includes a first data transmission-reception unit configured to transmit and receive, to and from a main server, data pertaining to at least one of the fault information or the repair history of the vehicles, at preset periodic intervals. The main server is configured to classify and manage the data by types of the vehicles. The vehicle controllers each includes a plurality of electronic control units (ECUs) capable of storing the fault information in response to an occurrence of a fault, and a communication module configured to wirelessly communicate with the main server.
