Rotating Projection Turret for Multi-Direction Vehicle Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in optimizing the viewing angles of public service messaging, particularly on vehicles, which may not be optimally oriented for viewing and are impractical due to limited parking and frequent repositioning, and there is a need for open cockpit vehicles to safely present public interest messaging and act as geofencing access points.
Innovation Solution
A system and method for open cockpit vehicles, such as scooters and motorcycles, that project media messages on road surfaces using a turret system to adjust viewing angles and project messages based on motion detection, geographic location, and target orientation, incorporating a media projection subsystem with a turret system that can rotate to face targets or project maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a display is mounted on a vehicle, then outdoor public notification space is increased, but the display cannot be optimally oriented for viewing in multiple directions
Solution Approach 1:
The patent applies the dynamics principle by making the display orientation adjustable rather than fixed. The display can be rotated to different angles and positions, allowing it to adapt to various viewing directions and optimize visibility for pedestrians and vehicles approaching from different directions.
Solution Approach 2:
The display system is designed to serve multiple viewing directions and scenarios simultaneously. By enabling rotation and repositioning, a single display unit can function effectively for traffic approaching from multiple directions, eliminating the need for multiple separate displays.
2Duration of action of stationary object
If parking spots are limited to one or two hours, then vehicle availability for public notification is reduced, but frequent repositioning becomes necessary
Solution Approach 1:
The system is designed to be dynamically repositionable, allowing the vehicle to move between different locations and still maintain effective public notification capability. The adjustable display orientation compensates for changes in location, making frequent repositioning manageable.
3Productivity
If open cockpit vehicles are used for public messaging, then vehicle availability increases, but safety concerns arise from projecting messages while in motion
Solution Approach 1:
The system incorporates motion detection technology that provides feedback about the vehicle's movement state. When motion is detected, the system automatically adjusts or disables message projection to prevent safety hazards. When the vehicle is stationary, the system enables projection, ensuring safe operation.
4Device complexity
If a vehicle-mounted display is fixed in one orientation, then device complexity is reduced, but viewing optimization for multiple directions is lost
Solution Approach 1:
The display mounting system incorporates rotational and adjustable mechanisms that allow the display to be positioned at different angles and orientations. This dynamic capability enables optimization for multiple viewing directions while maintaining reasonable system complexity through standardized components.

AI summary
A portable projection turret deployment is provided with a media projection subsystem (MPS). The MPS has a display surface aligned in a vertical plane, as is conventional. At a first time, the MPS display surface is rotated to align in a first horizontal direction, as viewed from a plan (top-down) perspective. Alternatively stated, a horizontal direction is the direction that the MPS display screen faces, or the direction in which the MPS projects visual information. At a second time, the MPS display surface is rotated in a second horizontal direction. The first horizontal direction may be orthogonal to the second horizontal direction. In one aspect, the MPS display surface can be rotated in a plurality of horizontal directions. In another aspect, the MPS display surface can be rotated (spun) in a horizontal circle.
