Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used for driverless vehicle testing data, then authentication reliability can be maintained through centralized verification, but authentication time and cost increase significantly
Solution Approach 1:
The authentication system is segmented into multiple independent authentication nodes distributed across the network. Each node can independently verify simulation data, eliminating the single-point bottleneck of centralized verification. This segmentation enables parallel processing of authentication requests, reducing overall authentication time while maintaining reliability through distributed consensus.
Solution Approach 2:
A blockchain-based intermediary layer is introduced between the simulation data and authentication nodes. The blockchain serves as a trusted mediator that records and verifies authentication results immutably, allowing nodes to trust each other's verification without requiring centralized coordination. This intermediary enables efficient peer-to-peer verification while ensuring authentication reliability.
2Reliability
If traditional authentication methods are used for driverless vehicle testing data, then comprehensive verification can be performed, but authentication cost increases
Solution Approach 1:
The authentication system enables self-service through automated verification processes. Simulation data is automatically submitted to the blockchain and verified by authentication nodes without requiring manual intervention. The system uses automated consensus mechanisms and smart contracts to perform comprehensive verification, reducing labor costs while maintaining high authentication reliability.
Solution Approach 2:
The system changes the verification parameter from centralized manual review to distributed automated verification. By transforming the authentication process into algorithmic verification performed by multiple nodes, the system achieves comprehensive checking at lower cost. The blockchain's immutable ledger provides verification certainty without requiring expensive manual audit processes.
3Productivity
If multiple authentication nodes are used for verifying simulation data, then authentication efficiency improves, but system complexity increases
Solution Approach 1:
The blockchain platform provides universal functionality that simplifies the multi-node authentication system. The blockchain handles data storage, consensus reaching, and result recording for all authentication nodes uniformly. This universal infrastructure allows multiple nodes to operate efficiently without each node needing to implement complex individual verification logic, reducing overall system complexity while maintaining high authentication efficiency.
