Solution Overview
Problem
Existing communication networks and methods for providing mobility as a service (MaaS) face challenges in efficiently managing distributed ledgers, particularly in handling large volumes of journey data and ensuring data consistency across multiple service providers.
Innovation Solution
A communication network and method that utilize a distributed ledger, such as a blockchain, to maintain journey data of users across multiple nodes, enabling secure, transparent, and efficient data management while ensuring data consistency and integrity through consensus protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized gateway is used to manage mobility as a service, then service coordination is simplified, but system reliability and data consistency are reduced
Solution Approach 1:
The patent segments the centralized gateway functionality into multiple distributed nodes that each maintain a copy of the ledger. Instead of one central authority, the system divides coordination functions across multiple independent nodes, achieving both operational simplicity through standardized interfaces and reliability through distributed data storage and consensus mechanisms.
Solution Approach 2:
The patent implements beforehand cushioning by creating redundant copies of the ledger across multiple nodes before any potential failure or inconsistency can occur. This proactive distribution of data ensures that if one node fails or provides inconsistent data, other nodes maintain the correct state, cushioning against potential reliability issues.
2Reliability
If distributed ledger technology is implemented across multiple nodes, then data consistency and reliability are improved, but system complexity increases
Solution Approach 1:
The patent implements feedback through consensus protocols where nodes continuously communicate and validate transactions against the ledger state. Each node provides feedback about its local state, and the system uses this feedback to maintain global consistency automatically, reducing the perceived complexity for individual nodes while ensuring overall reliability.
Solution Approach 2:
The patent applies universality by designing standardized interfaces and protocols that allow different types of nodes (service providers, users, validators) to interact through common mechanisms. This multi-functionality approach enables the same distributed ledger infrastructure to serve multiple purposes (transaction processing, data storage, consensus validation) without proportionally increasing complexity.
3Reliability
If journey data is stored on multiple nodes, then data security and integrity are enhanced, but data access efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-processing and indexing journey data before it needs to be accessed. Nodes maintain optimized data structures and indexes in advance, allowing efficient queries without scanning the entire distributed ledger. This preliminary organization of data enables fast access while maintaining the security benefits of distributed storage.
Solution Approach 2:
The patent introduces intermediary mechanisms such as query coordinators or index nodes that mediate between users and the distributed data storage. These intermediaries handle access requests efficiently by routing queries to appropriate nodes or aggregating results, reducing the direct access burden on individual nodes while maintaining data integrity through the distributed architecture.
