Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing vehicle data and communications lack efficient management and dissemination of information across multiple vehicles, particularly in a fleet setting, with limited capabilities for two-way data transfer and authorization control.
Innovation Solution
A network-centric architecture featuring an onboard microserver system with a web-based server and subsystem microservers, combined with a ground mirror database for remote data replication and authorization, enabling two-way communication and data transfer while ensuring secure dissemination of information across a fleet of vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an onboard microserver system is used to collect and store data locally, then data extraction capability is improved, but communication management complexity increases
Solution Approach 1:
The ground mirror database acts as an intermediary between the onboard microserver and external systems. It receives data from the onboard microserver, maintains a replica copy, and handles all communication management operations including authorization and data dissemination to multiple users, thereby reducing the communication burden on the onboard system while preserving full data extraction capability
Solution Approach 2:
The system divides communication management functions into two segments: the onboard microserver handles local data collection and storage, while the ground mirror database handles remote communication management, authorization, and data distribution. This segmentation allows each component to specialize in specific tasks, reducing overall system complexity while maintaining enhanced data extraction capabilities
2Adaptability or versatility
If data is transferred remotely using satellite and cellular communications, then fleet management capability is improved, but communication time and data loss increase
Solution Approach 1:
The ground mirror database maintains a pre-synchronized replica copy of all data before remote access is needed. This preliminary data replication eliminates the need for real-time data transfer over satellite or cellular networks, as users can immediately access the pre-cached data locally at the ground station, significantly reducing communication time while maintaining full fleet management capability
Solution Approach 2:
Instead of transferring data in real-time over slow satellite and cellular connections, the system creates and maintains a copy of the entire database at the ground mirror database. This copying approach allows instant local access to fleet data without the time delays inherent in remote wireless communications, while preserving complete fleet management versatility
3Productivity
If a ground mirror database is implemented for two-way communication, then data dissemination efficiency is improved, but system complexity increases
Solution Approach 1:
The ground mirror database is designed as a universal platform that performs multiple functions: maintaining data replicas, handling authorization for multiple users, managing two-way communications, and distributing data to various fleet management applications. By consolidating these diverse functions into a single multi-functional system, the patent achieves high data dissemination efficiency while avoiding the complexity of coordinating multiple separate systems
Data Source
AI summary
A system and method for global product management includes an onboard microserver located on a vehicle, a plurality of subsystem microservers, and a ground mirror database configured to be located remote of the vehicle. The onboard microserver includes a computer processor, memory storage, and a web-based server enabling local and remote communications to and from the onboard microserver using standard internet protocols. The plurality of subsystem microservers are configured to communicate with the onboard microserver and each other. The ground mirror database includes a replica of data contained on the onboard microserver and the subsystem microservers, and the database and the onboard microserver are configured for two-way communications and data transfers. The ground mirror database operates as a gatekeeper for all information sent to and from the onboard microserver by monitoring, authorizing and controlling a dissemination of data to and from the onboard microserver.
