Vehicle Air Conditioning Colored Lighting Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems in vehicles do not provide effective long-term feedback on temperature settings, leading to driver distraction and safety risks due to the inability to distinguish between cooling and heating operations after acclimatization.
Innovation Solution
The method employs colored lighting elements to symbolize temperature settings, using primary colors like red, green, and blue to differentiate between warm, neutral, and cold temperature ranges, and assigns these colors to specific airflow zones, allowing operators to intuitively recognize active zones and temperature levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If white light color temperature is adjusted to indicate temperature settings, then the feedback is initially visible, but after a short period of acclimatization, humans can no longer perceive the change and distinguish between cooling and heating operations
Solution Approach 1:
The patent applies color changes by using different colored lights (e.g., blue for cooling, red for heating) to indicate temperature settings. This overcomes the limitation of white light color temperature adjustment, which humans cannot perceive after acclimatization. The colored lights maintain their distinguishability over time, allowing continuous feedback on whether the air conditioning is in cooling or heating mode.
2Adaptability or versatility
If multiple setting options are provided for air conditioning (target temperature, ventilation level, air outlet direction, zone temperatures), then the air conditioning functionality is comprehensive, but the driver can easily be distracted from traffic
Solution Approach 1:
The patent implements visual feedback through colored lights that immediately indicate the current air conditioning mode (cooling/heating) and settings. This feedback allows drivers to quickly understand the system state without needing to study multiple displays or menus, reducing cognitive load and distraction while maintaining comprehensive air conditioning control capabilities.

AI summary
A method for feedback of a temperature setting of an air-conditioning device involves adjusting a light color of at least one lighting element for the display of a set temperature. The adjusted light color corresponds to a temperature setting of an airflow zone in a motor vehicle.
