Vehicle Display System with Camera View for Obstructed Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile display systems for vehicles obstruct the operator's view when in an operative position, posing safety concerns due to obstructed exterior views.
Innovation Solution
A mobile display system with an electronically powered display assembly, such as an LCD or scrolling billboard, and a viewing assembly comprising cameras and camera displays strategically placed to provide clear, safe observation of obstructed areas, allowing the operator to maintain a clear view while the display is in operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a display assembly is positioned on the exterior of the vehicle for advertising purposes, then the advertising visibility is improved, but the operator's field of vision is obstructed
Solution Approach 1:
A camera system is introduced as an intermediary device to capture images of the area obstructed by the display assembly. The camera feed is then displayed on interior display screens, allowing the operator to view obstructed areas without the display assembly blocking their direct line of sight. This intermediary solution resolves the contradiction by transferring the visual information from the obstructed exterior area to the operator's interior viewing area.
Solution Approach 2:
The camera system creates a visual copy or replica of the obstructed exterior area and displays it on interior screens. This copy allows the operator to observe the area that would otherwise be blocked by the display assembly, effectively duplicating the visual information in a location that does not obstruct the operator's view.
2Adaptability or versatility
If a display assembly is placed on the vehicle for advertising, then the advertising display function is improved, but the vehicle operation safety deteriorates
Solution Approach 1:
The camera system serves as a safety intermediary by providing continuous visual monitoring of areas obstructed by the display assembly. This allows the operator to maintain awareness of the vehicle's exterior environment despite the display assembly's presence, thereby maintaining operational safety while enabling the advertising function.
Solution Approach 2:
The camera system provides real-time visual feedback to the operator about conditions in areas obstructed by the display assembly. This feedback loop ensures the operator remains informed about the vehicle's surroundings, maintaining safety awareness while the display assembly performs its advertising function.

AI summary
A vehicle mounted display system generating advertising and/or other displayed messages which are clearly viewable from at least a rear exterior vicinity of the vehicle. An electronically powered display may comprise a digital display screen, such as an LCD, or a mechanically driven but electronically powered scrolling assembly. A mounting assembly selectively disposes the display assembly between operative and stored positions and a viewing assembly including at least one camera disposed to observe exterior areas which are obstructed by the operatively positioned display assembly. The viewing assembly also comprises a camera display disposed to be clearly viewable by the vehicle operator enables the operator to the view the obstructed areas.
