Vehicle Mesh Data Logging Under Intermittent Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, especially aircraft, face challenges in transmitting and storing data due to weight or connectivity limitations, and the volatility of reliable connections, which can lead to data loss during emergencies or remote operations.
Innovation Solution
A system and method that utilize a computing device to receive vehicle data, connect to a second device via a mesh network, authenticate the second device, generate vehicle collection data, and store it in a recorder database, even in the absence of network identification, ensuring data integrity and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted continuously over volatile networks, then data analysis capability is improved, but data loss risk increases during emergencies or remote operations
Solution Approach 1:
The system performs preliminary actions by continuously storing vehicle data in local storage devices before transmission is needed. This ensures data is preserved and ready for transmission when network connectivity becomes available, preventing data loss during emergencies or remote operations where connections may be interrupted.
Solution Approach 2:
The patent introduces an intermediary storage layer (local storage devices on the vehicle) between data generation and network transmission. This intermediary buffer decouples the reliability of data collection from the reliability of network transmission, allowing data to be stored securely locally until a reliable connection is available.
2Loss of information
If computing power is increased for onboard data analysis, then analysis capability is improved, but vehicle weight increases
Solution Approach 1:
The patent extracts the heavy computational analysis function from the vehicle and relocates it to remote servers. The vehicle retains only minimal data processing capabilities for data collection and preparation, while complex analysis is performed externally, significantly reducing onboard computing hardware requirements and vehicle weight.
Solution Approach 2:
The patent replaces physical onboard computing hardware with a network-based computational system. Instead of installing heavy processing equipment in the vehicle, the solution uses communication infrastructure and remote servers to provide the necessary computational power, substituting mechanical/physical systems with information-based systems.
3Reliability
If mesh network authentication is implemented, then data security is improved, but device complexity increases
Solution Approach 1:
The authentication module serves multiple functions: it authenticates devices joining the mesh network, manages cryptographic key pairs, verifies data integrity, and controls access permissions. By consolidating these security functions into a single multi-functional module, the system achieves high security without proportionally increasing overall system complexity.

AI summary
A system for transmitting and storing data based on a connection for a vehicle is presented. The system includes a computing device, the computing device configured to receive a vehicle data, communicatively connect the computing device to a second device as a function of a mesh network, authenticate a second device as a function of an authentication module, generate a vehicle collection datum as a function of the vehicle data, communicate the vehicle collection datum to the second device as a function of the mesh network, and store the vehicle collection datum in a recorder database as a function of a lack of identification of the mesh network.
