Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle interior lighting systems do not effectively communicate driving dynamics to the driver, particularly regarding longitudinal and lateral acceleration limits, which can lead to loss of control or traction issues.
Innovation Solution
A control device that evaluates current driving status parameters, such as longitudinal and lateral acceleration, to adjust the lighting situation within the vehicle, providing visual feedback on the driver's performance relative to physical limits, using LEDs to indicate safe and unsafe driving conditions through color, frequency, and intensity changes.

Engineering Contradiction Analysis
1Loss of information
If ambient lighting is used to create atmospheric lighting situations, then the lighting device can illuminate the vehicle interior, but it cannot effectively communicate driving dynamics to the driver
Solution Approach 1:
The lighting device is designed to perform multiple functions: it creates atmospheric lighting situations for passenger comfort while simultaneously communicating driving dynamics information to the driver. The control device enables the lighting system to adapt its function based on driving conditions, switching between ambient lighting mode and driving feedback mode using the same hardware infrastructure.
Solution Approach 2:
The system implements feedback by using the lighting device to communicate driving status information back to the driver. The control device continuously monitors driving parameters (acceleration, steering angle, etc.) and translates them into visual lighting patterns that provide real-time feedback about vehicle dynamics and traction conditions to the driver.
2Loss of information
If the lighting device is controlled based on driving status evaluation, then driver awareness of driving dynamics is enhanced, but the device complexity increases
Solution Approach 1:
The control device leverages existing vehicle sensors and processing capabilities to evaluate driving status, avoiding the need for dedicated complex hardware. The same control unit that manages other vehicle functions is used to process driving parameters and control the lighting device, thereby reducing overall system complexity while maintaining comprehensive driving status monitoring.
Solution Approach 2:
The control device utilizes the vehicle's existing sensor network and processing systems to provide driving status evaluation and lighting control. Rather than requiring a separate complex evaluation system, the control device integrates with the vehicle's existing self-diagnostic and monitoring capabilities to derive driving status information from available sensor data.
3Reliability
If the lighting device provides detailed driving feedback, then driver awareness and control are improved, but the ease of operation decreases
Solution Approach 1:
The lighting device operates autonomously based on driving status evaluation without requiring manual driver input. The control device automatically interprets driving parameters and translates them into appropriate lighting feedback patterns, eliminating the need for the driver to manually control or interpret complex lighting settings while maintaining intuitive and easy operation.
