Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If indicator lights operate at fixed brightness, then device complexity is reduced, but visibility in varying ambient light conditions deteriorates
Solution Approach 1:
The indicator light system automatically adjusts its brightness by capturing images with an image capturing device, processing the images to determine ambient light intensity, and generating control signals without requiring dedicated light sensors or manual intervention
Solution Approach 2:
The image capturing device serves dual purposes: capturing operational status information and determining ambient light intensity for automatic brightness adjustment, eliminating the need for separate light sensing components
2Illumination intensity
If dedicated light sensors are added to adjust indicator light brightness, then visibility in varying light conditions is improved, but device complexity and cost increase
Solution Approach 1:
The image capturing device performs multiple functions including capturing operational status and determining ambient light intensity, replacing the need for dedicated light sensors
Solution Approach 2:
The system uses its own image capturing and processing capabilities to determine ambient light conditions and adjust indicator light brightness autonomously

AI summary
A method, for operating an indicator light mounted to an exterior of a work machine, includes receiving, by a controller, a digital input image of an environment surrounding the work machine from an image capturing device. Also, the method includes processing, by the controller, the digital input image to determine an ambient light intensity of the environment. In addition, the method includes generating, by the controller, based on the determined ambient light intensity of the environment, one or more control signals to correspondingly adjust at least one attribute of light output by the indicator light.
