Adaptive Window Illumination System for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window illumination systems fail to adaptively improve visibility through windows in varying light conditions and do not effectively communicate information to drivers or occupants without relying on external accessories like spectacles or additional lighting.
Innovation Solution
A method and system that detects environmental light conditions and activates an edge-mounted illumination system on windows using LEDs that emit a range of colors, allowing for intensity and wavelength adjustment to enhance visibility and communicate information, such as through color changes for emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an illumination system is fixedly attached to the lower edge of the window pane, then the window pane is easy to locate in darkness, but the system cannot adaptively improve visibility through the window in varying light conditions
Solution Approach 1:
The illumination system transitions from a static, fixed attachment to a dynamic system with multiple degrees of freedom. The illumination device can rotate about a first axis and tilt about a second axis, allowing it to adaptively position light output toward different portions of the window pane based on detected viewing conditions, thereby resolving the contradiction between fixed positioning and adaptive functionality
Solution Approach 2:
The system incorporates sensors that automatically detect light conditions and trigger appropriate illumination responses without requiring external control. The illumination device self-adjusts its orientation and activation based on environmental conditions, eliminating the need for manual operation while maintaining adaptability to varying light conditions
2Illumination intensity
If the illumination system emits light into the window pane, then visibility of the window pane is improved, but the system cannot communicate information to the viewer
Solution Approach 1:
The illumination device incorporates multiple light sources emitting different wavelengths corresponding to different colors. By selectively activating specific light sources or combinations thereof, the system can display different colors to convey information to the viewer while simultaneously improving window visibility, thus resolving the contradiction between illumination and information communication
Solution Approach 2:
The illumination system is designed to perform multiple functions: it illuminates the window pane to improve visibility, and it communicates information through color variations. This multi-functional design allows a single system to address both the visibility improvement need and the information communication need without requiring separate systems
3Illumination intensity
If the illumination system is activated to improve visibility, then the environment viewing is enhanced, but energy consumption increases
Solution Approach 1:
The system incorporates sensors that continuously monitor environmental light conditions and provide feedback to the control logic. Based on this feedback, the system intelligently activates or deactivates the illumination device, ensuring it operates only when necessary to improve visibility, thereby minimizing energy consumption while maintaining visibility enhancement when needed
Solution Approach 2:
The illumination system dynamically adjusts its operation based on real-time environmental conditions. Rather than continuous operation, the system activates illumination only when sensors detect conditions requiring improved visibility, and adjusts the orientation and intensity of light output dynamically, reducing overall energy consumption while maintaining effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system improves visibility by adapting light intensity and color to environmental conditions, reducing the need for external accessories and enhancing safety by providing adaptive lighting that communicates information effectively to drivers and occupants.
Implementation Method 1
activating an illumination system adjacent an edge of the window. The illumination system is activated in a manner to direct light into the window
Implementation Method 2
The light condition may be detected by an environmental sensor and the illumination system activated based on signals generated by the environmental sensor

AI summary
A method of improving visibility for a person viewing an environment through a window includes detecting a light condition in the environment and, in responses to nature of the detected light condition, activating an illumination system adjacent an edge of the window to direct light into the window. The light is of the proper intensity and a wavelength to improve visibility of the environment as viewed through the window. The light condition may be detected by an environmental sensor and the illumination system activated based on signals generated by the environmental sensor.
