Vehicle Dashboard Language Setting via Portable Device Index
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle dashboard systems lack a simple and efficient method to switch between multiple languages for display, requiring complex user interactions and limited language support.
Innovation Solution
A system comprising a dashboard device and a portable electronic device that communicate to set the language using a processor, storage components, and Unicode databases, allowing automatic language selection based on machine codes and unique language indices, with the ability to update firmware and application programs for expanded language support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple language packs are stored in the dashboard device, then language support is expanded, but device complexity increases
Solution Approach 1:
The system uses a universal language index mapping mechanism that works across different language packs. The processor compares language indices from the portable device with supported language indices in the dashboard device, enabling a single unified interface to support multiple languages without requiring separate control mechanisms for each language pack.
Solution Approach 2:
The dashboard device pre-stores multiple language packs and their corresponding language indices in the storage component. The processor is pre-programmed with the logic to compare received language indices against the supported language indices table, enabling automatic language selection without requiring real-time complex processing or user configuration.
2Ease of operation
If automatic language selection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system enables automatic language selection where the dashboard device autonomously determines the appropriate language by comparing the language index received from the portable device with its supported language indices. This self-service mechanism eliminates the need for manual language configuration by users while maintaining operational simplicity.
Solution Approach 2:
The processor implements a feedback mechanism by comparing the received language index from the portable device against the stored supported language indices. Based on this comparison feedback, the system automatically selects and applies the appropriate language pack, ensuring correct language display without user intervention.
3Adaptability or versatility
If language packs are updated through firmware updates, then adaptability is improved, but loss of time increases
Solution Approach 1:
The system merges the language pack updates with regular firmware update processes. When firmware updates are performed on the dashboard device, new language packs or updated language data are bundled and installed simultaneously, eliminating the need for separate language update operations and reducing overall update time.

AI summary
A dashboard device of a vehicle includes a storage component and a processor. The storage component stores a plurality of different language packs and a first national table listing a first number of unique language indices associated respectively with the language packs. The processor is coupled to the storage component and is programmed to, in response to receipt of a machine code and a second number related to another plurality of unique language indices from a portable electronic device, use one of the language packs to set language used on the dashboard device based on content of the machine code and a relationship between the first and second numbers.
