In-Vehicle Meter Design Switching for Contextual Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems lack flexibility and user customization, as users find pre-designed meter displays either difficult to create or not suitable for specific driving conditions, leading to user dissatisfaction and inappropriate data presentation.
Innovation Solution
An in-vehicle display apparatus that allows users to select and switch between multiple authorized meter design files based on usage conditions, with a server managing and authenticating these designs, ensuring only reliable and contextually appropriate displays are shown, including automatic switching based on predefined conditions such as speed or location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to create custom meter designs using a keyboard or mobile computer, then user customization capability is improved, but device complexity and time required to create a satisfactory design increases
Solution Approach 1:
The system pre-provides multiple meter design files with different characteristics (urban road design, expressway design, etc.) that have been prepared in advance. Users can directly select from these pre-configured designs without needing to create them from scratch, thus reducing the time and complexity of design creation while maintaining customization capability.
Solution Approach 2:
The system stores and manages multiple copyable meter design files that can be selected and applied. Instead of requiring users to create unique designs, the system provides ready-made design templates that can be copied and used directly, simplifying the customization process while maintaining design variety.
2Adaptability or versatility
If multiple meter design files are stored and selectable, then adaptability to different driving conditions is improved, but the system cannot ensure appropriate design selection for specific conditions
Solution Approach 1:
The system automatically determines the current driving condition (urban road or expressway) and provides feedback by selecting and displaying the appropriate meter design file corresponding to that condition. This feedback mechanism ensures that the correct design is displayed without requiring manual user judgment, solving the problem of inappropriate design selection.
Solution Approach 2:
The system performs self-service by automatically selecting the appropriate meter design file based on the determined driving condition. Instead of relying on users to manually choose the correct design, the system autonomously matches the current condition with the suitable pre-configured design, ensuring appropriate display selection.
3Device complexity
If a fixed meter design provided by a device maker is used, then device simplicity is maintained, but user satisfaction decreases due to lack of customization
Solution Approach 1:
The system transitions from a static fixed design to a dynamic multi-design system. Multiple meter design files are stored, and the system can dynamically switch between them based on user selection or determined driving conditions. This dynamic capability maintains system simplicity in terms of user interface while providing extensive customization options internally.
Solution Approach 2:
The system implements multi-functionality by incorporating multiple meter design files that can serve different purposes (urban road display, expressway display, etc.). This universal approach allows a single system to fulfill multiple display needs without requiring separate devices, maintaining simplicity while enhancing adaptability.
