Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles share road change data in existing systems, then navigation information can be updated, but data value uncertainty and platform incompatibility prevent effective sharing
Solution Approach 1:
The system segments the data sharing process into distinct phases: local validation phase where changes are verified by threshold number of vehicles in a geographic area, then global propagation phase where validated changes are shared across the network. This segmentation resolves the contradiction by ensuring data reliability through local validation before enabling efficient global navigation updates.
Solution Approach 2:
The patent introduces an intermediary validation mechanism using blockchain technology and threshold cryptography that mediates between data contributors and navigation systems. This intermediary layer verifies data authenticity and compatibility before integration, resolving the reliability issue while maintaining efficient update propagation.
2Reliability
If a decentralized validation system is implemented to ensure data integrity, then data security improves, but system complexity increases
Solution Approach 1:
The system implements self-service validation where vehicles autonomously validate road changes using their own sensors and the validation logic distributed across the network. Vehicles independently determine whether observed changes meet the threshold criteria, eliminating the need for centralized validation infrastructure and reducing system complexity while maintaining data integrity.
Solution Approach 2:
The patent creates a universal validation protocol that works across different vehicle platforms and manufacturers. The threshold cryptography mechanism and blockchain validation are platform-agnostic, allowing any vehicle to participate in validation without requiring platform-specific infrastructure, thus reducing overall system complexity.
3Manufacturing precision
If road changes are validated by threshold number of vehicles before integration, then map accuracy improves, but data sharing time increases
Solution Approach 1:
The system performs preliminary validation actions at the local level before global integration. Changes are pre-validated by threshold vehicles in the immediate geographic area, and only then are they propagated globally. This preliminary action ensures map accuracy while minimizing overall validation time by parallelizing the validation process across multiple vehicles simultaneously.
Solution Approach 2:
The patent applies partial validation by requiring threshold number of vehicles to validate changes locally rather than requiring universal validation across the entire network. This partial action is sufficient to ensure map accuracy for that geographic area while significantly reducing the time required compared to full network validation.

AI summary
Methods and systems are presented for sharing detected changes in roads using blockchains in a network. The network includes vehicles operable to detect a change in a road, a plurality of local blockchains, and a global blockchain. The vehicles are divided into groups of local vehicles. The plurality of local blockchains includes local blocks of changes, wherein after a first vehicle publishes a change of the road among a group of local vehicles, a block of the change is integrated into a local blockchain when at least a local threshold number of the local vehicles endorse the change. The global blockchain includes blocks of changes, wherein a block of the change is integrated into the global blockchain when at least a global threshold number of the vehicles endorse the change. A token is awarded to the first vehicle.
