Vehicle Window Shade Emergency Light Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency situation notification devices for vehicles, such as tripods and balloon-based systems, face issues with reduced visibility due to low placement and lack of lighting, leading to difficulty in recognizing alerts, especially at night, and increase vehicle weight with additional equipment.
Innovation Solution
A dangerous situation notification assembly for vehicle window shades that incorporates a light-emitting unit using optical fibers or light sources to display alerts on the shade or rear window, enhancing visibility with flickering lights and optional warning sounds to prevent secondary accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a tripod or balloon-based emergency indication device is used, then emergency situation can be notified, but visibility is reduced due to low placement and lack of lighting
Solution Approach 1:
The patent combines the emergency notification function with the existing window shade device by integrating light-emitting units into the shade structure. This merging eliminates the need for separate tripod or balloon-based indication devices, while providing integrated lighting to enhance visibility of the emergency notification.
Solution Approach 2:
The patent introduces light-emitting units as an intermediary element within the window shade device to enhance the visibility of the emergency notification. These light-emitting units serve as a mediator between the notification message and the external environment, ensuring the notification can be seen clearly during nighttime or low-visibility conditions.
2Reliability
If balloon and compressed air container are added to notify emergency situation, then emergency notification is achieved, but vehicle weight increases
Solution Approach 1:
The patent makes the window shade device multi-functional by integrating emergency notification capability into its existing structure. The window shade device, which already exists in the vehicle, is enhanced with light-emitting units to provide emergency notification, eliminating the need for additional dedicated equipment like balloons and compressed air containers.
Solution Approach 2:
The patent enables the window shade device to serve itself by providing emergency notification functionality through integrated light-emitting units. The device uses its own structure and power supply system to generate and display emergency notifications, without requiring external辅助设备 like tripods or balloon systems.
3Ease of operation
If emergency indication device is placed on the road surface, then it can be positioned, but visibility is reduced as it is below eye level of approaching drivers
Solution Approach 1:
The patent transitions the emergency notification from a ground-level placement (horizontal dimension) to a vertical placement on the window shade device. By utilizing the vertical space of the vehicle's window shade, the notification is positioned at eye level or above for approaching drivers, dramatically improving visibility while maintaining ease of deployment since the shade device is already mounted on the vehicle.
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
Improves visibility of emergency situations for approaching drivers by selectively emitting light on the shade or rear window, reducing the risk of secondary accidents through enhanced notification during breakdowns or accidents, both day and night.
Implementation Method 1
a light source unit disposed adjacent to the shade and configured to provide light to the dangerous situation notification unit so that the dangerous situation notification unit selectively emits light
Implementation Method 2
the dangerous situation notification unit may be formed of optical fibers in the shade

AI summary
The present disclosure relates to a dangerous situation notification assembly for a window shade device of a vehicle and a dangerous situation notification assembly for a rear window of a vehicle. A dangerous situation notification assembly for a window shade device for vehicles, according to the present disclosure, which has a shade provided on any one of upper and lower sides of a rear window and reciprocates between a shading position where the rear window is shaded and a rolling position where the shade is rolled from the shading position, comprises: a dangerous situation notification unit which is arranged in the shade and selectively emits light at the shading position of the shade to output a dangerous situation; and a light source unit which is adjacent to the shade and supplies light to the dangerous situation notification unit so that the dangerous situation notification unit selectively emits light.
