Side Projection Lamp Structure for Rear Blind-Spot Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side mirrors on mobility devices have a limited field of view due to their installation position, making it difficult to secure rear lateral sight and illuminate specific images on road surfaces or outer surfaces effectively, especially in blind spots.
Innovation Solution
An apparatus comprising a side projection lamp with a rear recognizer, an image transmitter, and a reflection unit that projects light onto a road surface or outer surface, allowing for improved rear lateral sight and image illumination, with adjustable projection position and size, and a reduced side part size to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional side mirror is installed on the passenger seat side, then the driver can observe rear lateral sight, but the reflection angle is very small and the field of view in blind spot cannot be secured
Solution Approach 1:
Instead of using a conventional mirror that reflects light from the rear lateral direction to the driver's eye, this invention inverts the approach by using a projection lamp that directly projects the rear lateral image onto the road surface in front of the vehicle. The driver then observes the projected image on the road surface, which provides a much larger viewing angle and eliminates blind spots while maintaining rear lateral sight observation.
2Loss of information
If a side mirror is installed on the body surface or door, then the driver can observe traffic situation, but the device size and complexity increase
Solution Approach 1:
This invention extracts the core function of observing rear lateral sight and traffic situation from the complex side mirror structure and implements it through a simplified projection lamp system. The projection lamp, image transmitter, and reflection unit work together to project images onto the road surface, eliminating the need for traditional mirror mechanisms while maintaining the essential observation function.
3Loss of information
If a projection lamp is used to illuminate images on the road surface, then visibility and communication with driver are improved, but the light movement space and side part size increase
Solution Approach 1:
This invention utilizes the road surface as a two-dimensional projection screen, transforming the observation space from the traditional mirror surface to the extensive road surface area. By projecting images onto the road surface in front of the vehicle, the system achieves high visibility without requiring a large side part structure, as the projection area extends forward rather than laterally.
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 apparatus effectively secures rear lateral sight and illuminates specific images on mobility devices, improving driver communication and reducing the overall size of the side part, thereby enhancing visibility and reducing blind spots.
Implementation Method 1
a reflection unit installed in the light movement space of the side part and projecting the image on a road surface or an outer surface of the mobility device by reflecting the light illuminated from the image transmitter

AI summary
Proposed is an apparatus for a side projection lamp of a mobility device having a structure as described may secure rear lateral sight from opposite lateral sides of the mobility device and illuminate light of a specific image on a road surface or an outer surface of the mobility device, thereby being allowed to communicate with a driver. In addition, as an image transmitter configured to generate the specific image is installed on a vehicle body or a door side, a size of a side part configured to secure rear sight may be reduced.
