Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smartphone navigation applications are used to provide navigation data, then the need for onboard GPS modules is eliminated, but the lack of standardization in data formats makes data integration difficult
Solution Approach 1:
The patent introduces a standardized data interface layer that acts as an intermediary between diverse smartphone navigation applications and the vehicle computing system. This intermediary layer receives various formats of navigation data from different applications, standardizes them into a common format, and then processes them for vehicle output devices. This resolves the contradiction by enabling broad compatibility while managing standardization complexity through a dedicated mediation layer rather than requiring direct integration of each application format.
Solution Approach 2:
The patent applies parameter changes by transforming navigation data from various source formats into a standardized parameter set that the vehicle computing system can process. The system identifies key parameters from different data sources (such as position coordinates, route information, turn-by-turn instructions) and normalizes them into consistent formats, allowing the system to work with diverse smartphone applications without requiring each to adhere to a specific format.
2Adaptability or versatility
If diverse smartphone navigation applications are integrated, then more navigation sources are available, but the variance in data formats among applications creates processing difficulties
Solution Approach 1:
The standardized data interface serves as a mediator that simplifies data processing by handling format conversion automatically. The system receives data from multiple smartphone navigation applications in different formats, the intermediary standardizes these formats, and then the vehicle computing system processes the unified data without needing to handle format variations. This maintains ease of operation while supporting diverse application sources.
Solution Approach 2:
The patent implements a universal data interface that can handle multiple types of navigation data from different sources through a single standardized mechanism. This multi-functional interface is designed to accept various data formats and convert them uniformly, allowing the system to work with any smartphone navigation application that provides compatible navigation information, thus maintaining operational simplicity while supporting versatility.
3Adaptability or versatility
If a standardized data interface is implemented, then data compatibility is improved, but additional data processing steps are required
Solution Approach 1:
The system performs preliminary standardization of navigation data as it is received from smartphone applications, converting data to the standardized format immediately upon receipt rather than delaying processing. This preliminary action ensures that all subsequent processing steps work with uniformly formatted data, improving overall efficiency despite the additional standardization step. The standardization is integrated into the data reception workflow rather than being a separate post-processing step.
Data Source
AI summary
A system includes a processor configured to communicate wirelessly with a mobile device, wherein the processor is further configured to receive output data from a navigation application running on the mobile device. The processor is also configured to send data back through the mobile device to a standardization system, including a request for standardization, running on a remote system, if the output data is in an unusable format. Also, the processor is configured to receive a standardized form of the data, having been standardized by the remote standardization system. The processor is further configured to process the standardized data to provide navigation directions through one or more vehicle outputs controllable by the processor.
