Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pathway articles use traditional authentication methods, then integration with existing infrastructure is simpler, but security and reliability of pathway information are insufficient
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between pathway articles and autonomous vehicles. The blockchain serves as a decentralized mediator that stores and verifies authentication information without requiring centralized control, thereby enhancing reliability while maintaining reasonable system complexity through standardized integration protocols
Solution Approach 2:
The patent replaces traditional centralized authentication mechanisms with a distributed blockchain-based system. This substitution eliminates single points of failure and centralized vulnerability, improving reliability through decentralization while the modular architecture keeps implementation complexity manageable
2Reliability
If blockchain authentication is implemented on all pathway articles, then security and authenticity verification are improved, but infrastructure cost and implementation complexity increase
Solution Approach 1:
The patent segments the blockchain authentication system into modular components: authentication modules embedded in pathway articles, verification software in autonomous vehicles, and a decentralized blockchain network. This segmentation allows selective implementation and reduces overall infrastructure complexity while maintaining security benefits
Solution Approach 2:
The patent designs the blockchain authentication system to serve multiple functions: authenticating pathway articles, providing immutable records of pathway information, enabling decentralized verification, and facilitating future expansion to other autonomous system applications. This multi-functionality justifies implementation costs through versatile utility
3Reliability
If traditional pathway recognition systems are used, then integration with existing vehicles is easier, but safety and efficiency of autonomous navigation are reduced
Solution Approach 1:
The patent implements feedback mechanisms where autonomous vehicles continuously verify pathway article authenticity through blockchain validation and adjust navigation decisions based on verification results. This feedback loop enhances navigation safety by ensuring reliable pathway information while the automated verification process manages system complexity through algorithmic decision-making
4Reliability
If authentication verification is performed for each pathway article, then security against counterfeit articles is improved, but processing time and computational load increase
Solution Approach 1:
The patent implements preliminary authentication by pre-registering pathway articles in the blockchain network before deployment. This preliminary action allows vehicles to perform faster verification queries against already-registered articles rather than conducting full authentication protocols in real-time, thereby maintaining high counterfeit detection capability while reducing processing time during actual navigation
Data Source
AI summary
The disclosure is directed to an article, such as a pathway article or a sheeting. The article includes a physical surface having a code embodied thereon. The code is associated with pathway information in transaction data stored by a blockchain managed by a consensus network of node. The pathway information indicates one or more characteristics of a vehicle pathway, wherein the pathway information provides at least one of: information descriptive of at least a portion of the vehicle pathway, or vehicle operation instructions associated with the portion of the vehicle pathway.
