In-Vehicle Navigation Interface for Remote Destination Download
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle navigation systems lack customization options based on vehicle capabilities and user preferences, and do not efficiently manage multiple destinations or adapt to varying network conditions.
Innovation Solution
A system that allows users to remotely select destinations via a web interface and wirelessly download them to their vehicle's telematics unit, customizing the navigation experience based on vehicle capabilities and user preferences, and optimizing for network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard navigation interface is used, then the system is simple to operate, but it cannot be customized based on vehicle capabilities and user preferences
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple interface templates with different levels of customization before the user needs them. When a user accesses the navigation system, pre-prepared interface configurations are immediately available based on detected vehicle capabilities and user preferences, eliminating the need for real-time complex customization while still providing adaptability.
Solution Approach 2:
The interface dynamically adapts its complexity based on detected vehicle capabilities and user preferences. The system automatically adjusts which interface elements are displayed or hidden, transforming a static interface into a dynamic one that provides customization without requiring the user to manually configure complex settings.
2Productivity
If multiple destinations are managed through separate processes, then each destination can be handled individually, but the system efficiency decreases
Solution Approach 1:
The system merges multiple destination management operations into a single integrated process. Instead of handling each destination separately through individual processes, the system combines destination selection, validation, and download operations into one unified workflow that processes multiple destinations simultaneously, significantly improving efficiency while maintaining manageable complexity through modular architecture.
Solution Approach 2:
A universal destination management module is implemented that can handle multiple destinations through a single interface and process flow. This multi-functional module replaces multiple specialized processes, allowing the system to manage any number of destinations using the same underlying logic and code structure, thereby improving productivity without proportionally increasing system complexity.
3Reliability
If navigation data is downloaded without considering network conditions, then the download process is simple, but data availability and reliability decrease
Solution Approach 1:
The system implements feedback mechanisms that continuously monitor network conditions during the download process. Based on real-time feedback about network availability, bandwidth, and connectivity stability, the system dynamically adjusts download parameters such as retry attempts, data compression levels, and alternative data sources, ensuring reliable data acquisition without requiring complex manual configuration by the user.
Solution Approach 2:
The download system performs self-service by automatically detecting network conditions and adjusting its behavior accordingly. The system monitors its own operational environment, identifies network constraints, and independently optimizes the download process without external intervention, thereby improving reliability while keeping the user interface simple and the overall system complexity manageable.
Data Source
AI summary
The described method and system for providing navigation assistance to a user of a mobile navigation system includes presenting a web interface to the user, the web interface having one or more user-selectable fields including a destination field. Through the interface, the user can identify a desired destination and download data associated with the destination to a database associated with a call center. Later, the user may download the data to their mobile navigation device, e.g., their vehicle telematics unit, for navigational assistance. In an implementation, such assistance is provided in the form of turn-by-turn directions.
