Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telematics messaging systems are static and require significant effort to add or adjust features, such as message content and structure, necessitating re-writing of source code and firmware updates, which limits their adaptability and interoperability with diverse vehicle telematics devices.
Innovation Solution
Dynamic telematics messaging systems that include a vehicle telematics device and a server system with a processor and memory, capable of transcoding messages from various formats into a standardized format, identifying and processing message data using modules like sensor data and reverse geocoding, enabling automatic data processing and communication with multiple devices through a single gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional static telematics messaging systems are used, then system simplicity is maintained, but adaptability to diverse message formats and devices deteriorates
Solution Approach 1:
The patent introduces a message broker as an intermediary component that receives messages from multiple telematics devices using different formats and protocols, transcodes them into a standardized internal format, and routes them to appropriate applications. This mediator layer enables diverse devices to communicate without requiring changes to the core system architecture, thus improving adaptability while maintaining system simplicity.
Solution Approach 2:
The system dynamically changes message format parameters by maintaining a registry of supported message formats and protocols. When a new message arrives, the system identifies its format and applies the appropriate transcode configuration, allowing the system to adapt to diverse formats without hardcoding each format into the system logic.
2Adaptability or versatility
If source code rewriting and firmware updates are performed to add features, then system functionality is improved, but ease of operation and maintenance deteriorates
Solution Approach 1:
The patent implements a dynamic configuration system where message formats, transcode rules, and routing logic can be modified at runtime without requiring system restart or firmware updates. Configuration files and parameter settings can be adjusted to add new features or support new devices, making the system highly maintainable and easy to operate.
Solution Approach 2:
The system architecture is segmented into independent modular components: message reception layer, transcode layer, routing layer, and application layer. Each component can be independently configured, maintained, and updated. This modular segmentation allows feature additions without affecting the entire system, significantly improving ease of maintenance.
3Adaptability or versatility
If multiple device types are supported, then interoperability is improved, but device complexity increases
Solution Approach 1:
The message broker is designed as a universal platform that can handle multiple message formats, protocols, and device types through a single unified interface. By implementing format detection and automatic transcode configuration, the gateway achieves multi-functionality without requiring separate handling logic for each device type, thus improving interoperability while controlling complexity.
