Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles lack an effective way to display lap data and performance metrics in a visually engaging and dynamic manner, failing to provide real-time feedback on lap times and comparisons to previous best times.
Innovation Solution
An electronic display system with a graphical lap information display portion that includes a lap time differential indicator and an illuminated portion, controlled by a system that calculates and displays differential time values and adjusts lighting modes based on the rate of change of these values, allowing for real-time comparison and feedback on vehicular performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional displays are used to show lap data, then the display is simple and reliable, but the visual engagement and real-time feedback effectiveness are insufficient
Solution Approach 1:
The display system transitions from static to dynamic visualization by changing illumination colors and patterns in real-time based on lap performance data. The graphical display portion dynamically adjusts its visual properties to reflect differential time values and performance metrics, creating an engaging and informative display without requiring multiple physical display devices.
Solution Approach 2:
The system uses color-coded illumination to convey different performance states and differential time values. By varying the color and intensity of the illuminated portion based on performance data, the system provides intuitive visual feedback while maintaining a single display device, thus improving visual engagement without proportionally increasing complexity.
2Measurement precision
If detailed lap data is displayed continuously, then measurement precision is improved, but passenger distraction increases
Solution Approach 1:
The display system segments information presentation by using different visual elements (illumination color, intensity, and graphical patterns) to represent different aspects of lap performance. This segmentation allows precise lap time data to be conveyed through intuitive visual cues rather than continuous numerical displays, maintaining measurement precision while reducing cognitive load and distraction.
Solution Approach 2:
The system implements real-time visual feedback that automatically adjusts the display based on performance differential. When the vehicle is on track or ahead, the display provides encouraging visual feedback; when off-track or behind, it provides corrective feedback. This automated feedback mechanism delivers precise performance information without requiring constant passenger attention to detailed data.
3Productivity
If real-time lap data calculation is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: collecting vehicle sensor data, calculating lap times, determining differential values, and controlling the graphical display. By consolidating these functions into a single multi-functional controller rather than separate dedicated systems, the patent achieves real-time data processing while managing overall device complexity through functional integration.
