Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current on-board computer networking systems for managing vehicles and fleets lack efficient data collection, processing, and secure remote access, leading to inadequate management and maintenance decision-making.
Innovation Solution
A system comprising sensors, a certified processor, a database, and a computer network that generates and processes critical vehicle data, allowing selective remote storage and access through a user portal, with secure authorization and hierarchical data organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is collected and stored on the certified processor on the vehicle, then data availability for management decisions is improved, but data security and access control become more complex
Solution Approach 1:
The system segments data access by creating different user roles (operator, maintenance personnel, management) with specific permission levels. Each user type can access only the data and functions relevant to their role, thereby maintaining data security while simplifying the access control mechanism for each individual user.
Solution Approach 2:
The patent introduces a data buffer and communication bus as intermediaries between the certified processor and external access points. This intermediary layer manages data requests and permissions centrally, reducing the complexity of direct access control at multiple points in the system.
2Loss of time
If real-time data processing is implemented on the vehicle, then maintenance decision-making speed is improved, but system reliability requirements increase
Solution Approach 1:
The system performs preliminary data processing and analysis on the certified processor while the vehicle is operating. Critical parameters are continuously monitored and pre-evaluated, so that when maintenance decisions are needed, the analysis is already complete or near-complete, reducing decision time while maintaining reliability through progressive verification.
Solution Approach 2:
The patent implements feedback loops where processing results are continuously monitored and verified against predefined thresholds and conditions. This feedback mechanism ensures that real-time processing maintains system reliability by detecting and correcting anomalies before they compromise the system.
3Adaptability or versatility
If comprehensive vehicle data is stored remotely in a database, then fleet management capability is improved, but data transmission requirements and costs increase
Solution Approach 1:
The system extracts and transmits only the most critical and frequently accessed vehicle data to the remote database, while less critical data remains stored locally on the certified processor. This selective data extraction reduces transmission requirements and costs while maintaining comprehensive fleet management capability for the essential parameters.
Solution Approach 2:
The patent implements partial data transmission by sending data at optimized intervals and only when changes exceed predefined thresholds. This approach provides sufficient data for fleet management decisions without the excessive energy consumption of continuous full-data transmission.
