Rotatable Vehicle Projection Mapping for Wider Interior Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle projection systems have a limited field of view, requiring multiple projectors to cover larger areas, which is costly and space-intensive.
Innovation Solution
A rotatable projection device with a projector, depth detection camera, and infrared illumination source that aligns projections to the vehicle's interior geometry using a three-dimensional model, allowing for dynamic rotation and correction to ensure accurate projection over a broader area without additional projectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple projectors are provided to cover a broader projection area, then the projection field of view is increased, but the cost, space requirements, and wiring complexity increase
Solution Approach 1:
The patent applies the dynamics principle by making the single projector rotatable and adjustable in orientation. The projector can dynamically change its projection direction and angle to cover different areas of the vehicle interior, replacing the need for multiple fixed projectors. This is achieved through motorized rotation mechanisms that allow the projector to be positioned optimally for different projection surfaces.
Solution Approach 2:
The patent implements universality by designing a single projector system that can serve multiple functions and cover multiple projection areas. The rotatable projector can project onto different interior surfaces (windshield, dashboard, seats, etc.) by adjusting its orientation, making one device perform the work of multiple projectors would otherwise be needed.
2Area of moving object
If multiple projectors are installed to increase coverage area, then the projection field of view expands, but the space required in the vehicle increases
Solution Approach 1:
The dynamic rotation capability allows a single compact projector unit to cover the space that would otherwise require multiple larger projector installations. By rotating to different positions, one small device replaces the volume occupied by multiple projectors mounted at various locations.
Solution Approach 2:
The projection coverage is segmented into different temporal zones rather than spatial zones. Instead of having multiple projectors covering different areas simultaneously, one projector sequentially covers different areas by rotation, dividing the coverage task across time rather than space.
3Area of moving object
If multiple projectors are used to cover larger areas, then the projection field of view increases, but the wiring and installation complexity increases
Solution Approach 1:
A single universal projector system with rotation capability replaces multiple specialized projector installations. This eliminates the need for separate wiring harnesses, power supplies, and control systems for each projector, consolidating all connections into one system.
Solution Approach 2:
The patent merges the functions of multiple projectors into a single integrated system. The rotation mechanism, control system, and projection optics are combined into one unit, eliminating the need for separate installation and wiring of multiple independent projector systems.
