Unified Vehicle Data Interface for Multi-Source Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of online services in vehicles leads to user overload and distraction for drivers, as they must navigate multiple sources and applications to find relevant data, complicating the search and provision of media content while driving.
Innovation Solution
A method and system that capture user queries and automatically search for corresponding data across various sources, assigning suitable applications to display results, allowing users to access a wide range of data types without selecting specific sources, and dynamically adjusting based on driving conditions to enhance road safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sources and applications are made available for data search, then data versatility and coverage are improved, but user complexity and distraction increase
Solution Approach 1:
The system introduces an intermediary layer (the display device and control unit) that mediates between the user and multiple data sources. The user interacts with a single unified interface that automatically manages multiple sources, applications, and data formats, transforming complex multi-source search into a simple single-query operation.
Solution Approach 2:
The system creates a universal search interface that can handle multiple types of data sources (online services, local storage, cloud services) and applications through a single unified query mechanism. This universal interface abstracts away the differences between various sources and presentations, allowing users to search all sources simultaneously without needing to know which specific source to use.
2Loss of information
If multiple sources are searched for user queries, then data completeness is improved, but search time and processing complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing connections to multiple data sources and pre-configuring search parameters. When a user submits a query, the system simultaneously initiates searches across all connected sources rather than sequentially accessing them, significantly reducing total search time while maintaining data completeness.
Solution Approach 2:
The system maintains continuous search operations across multiple sources simultaneously, keeping all data channels active and querying them in parallel. This continuous parallel operation ensures that no useful data source is missed while minimizing the total time required to gather complete information from all sources.
3Measurement precision
If application-specific display is implemented, then data accuracy is improved, but system complexity increases
Solution Approach 1:
The system dynamically changes display parameters based on the type of data retrieved and the user's current context. Different data types (maps, media players, text information) are automatically presented with appropriate display formats and parameters, ensuring each type of information is displayed in the most accurate and useful manner without requiring manual configuration.
Data Source
AI summary
A method makes data available in a motor vehicle. A user query is entered using an input device of the motor vehicle. A plurality of sources are searched for data corresponding to the user query, and the search result associated with the found data is displayed by a display device of the motor vehicle. Respective applications of the motor vehicle are assigned to the search results by a data processing device. The applications are designed to reflect the data formats associated with the search results. Only these applications are displayed by the display device. A corresponding system makes the data available in the motor vehicle.
