Dynamic Vehicle Display Template Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern display systems in passenger vehicles often display empty fields, error messages, or incorrect information due to unavailability or malfunction of data, leading to confusion and annoyance for passengers.
Innovation Solution
A display system that retrieves information, evaluates its availability and metadata, and selects a suitable display template to format and display relevant data, ensuring smooth operation and correct information presentation even when data is unavailable or incorrect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display system permanently reserves space for all possible information fields, then the layout structure is simple and stable, but the display surface is wasted when certain information is unavailable
Solution Approach 1:
The display system dynamically adjusts the layout by selecting from multiple pre-defined templates based on data availability. The processing means evaluates which information fields contain valid data and automatically switches between different display templates to optimize space utilization while maintaining a clean appearance.
Solution Approach 2:
The system changes the display configuration parameters by selecting different templates that define various layout arrangements. Each template is optimized for specific data availability scenarios, allowing the system to adapt the display parameters (layout, positioning, content) based on the current state of information availability.
2Loss of information
If the display system shows all available information fields, then information completeness is improved, but error messages and empty fields confuse passengers
Solution Approach 1:
The processing means extracts and identifies which information fields contain valid data versus which fields are empty or contain errors. It then selectively displays only the relevant information fields while omitting empty or erroneous ones, thereby maintaining information completeness for available data while eliminating sources of passenger confusion.
Solution Approach 2:
The system converts the potential harm of data unavailability (empty fields, error messages) into a benefit by using the absence of data as a trigger to select alternative templates that maintain aesthetic appearance and avoid confusion. The evaluation of data quality becomes a useful mechanism for improving user experience.
3Adaptability or versatility
If the display system uses a fixed layout template, then the display structure is simple and reliable, but it cannot adapt to varying information availability
Solution Approach 1:
The system performs preliminary action by pre-defining multiple display templates that cover various data availability scenarios. These templates are prepared in advance and stored in the memory, allowing the processing means to quickly select the appropriate template based on current data conditions without requiring complex real-time layout calculations.

AI summary
The invention pertains to a display system for displaying messages in a passenger compartment of a vehicle, the system comprising: a display surface; a memory comprising a plurality of display templates; interfacing means adapted to retrieve information from an information system; processing means to evaluate said retrieved information and to select a display template from among said plurality of display templates conditionally on said evaluating; and formatting means configured to format said retrieved information in accordance with said selected template for displaying on the display surface. The invention also pertains to a corresponding method, comprising: retrieving (210) information from an information system; evaluating (220) said retrieved information; selecting (230) a display template from among a plurality of display templates conditionally on said evaluating; formatting (240) said retrieved information in accordance with said selected template; and displaying (250) said formatted information on a display surface of a display system.
