Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional theme park attractions using light projections to simulate three-dimensional objects are limited by hardware and software constraints, requiring large show spaces and often result in distorted or flattened 3-D effects due to architectural and robotic limitations.
Innovation Solution
A system utilizing a projector and a translucent scrim to simulate 3-D objects by projecting light onto an opaque surface and extending the object beyond the boundary through the scrim, with projection characteristics determined by a squinching algorithm to maintain visual authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional light projection systems are used to simulate 3-D objects, then the show space can be reduced, but the 3-D effect becomes distorted or flattened due to hardware and software limitations
Solution Approach 1:
The projection surface is divided into two distinct parts: an opaque surface for displaying the main body of the 3-D object and a translucent scrim for displaying the extension beyond the boundary. This segmentation allows each surface to be optimized for its specific function, with the opaque surface providing sharp, detailed projection and the scrim providing smooth transitions and depth extension, thereby eliminating distortion and flattening while managing system complexity
Solution Approach 2:
The translucent scrim acts as an intermediary element between the opaque surface and the projected light. It receives the projection and selectively transmits light to create the illusion of depth extension, serving as a mediator that bridges the gap between the 2-D projection surface and the perceived 3-D space, thus resolving the distortion issue without requiring complex hardware modifications
2Shape
If a large array of physical show elements or set props is used, then the 3-D effect is improved, but the show space requirement increases
Solution Approach 1:
Instead of using physical 3-D objects or set props that occupy real space, the system creates a visual copy of the 3-D object through projection mapping. The opaque surface displays the primary projection, and the translucent scrim extends this visual copy beyond the physical boundary, achieving authentic 3-D effects without requiring corresponding physical elements, thus eliminating the show space constraint
Solution Approach 2:
The system transitions from two-dimensional projection on a flat surface to a multi-dimensional visual effect by introducing the translucent scrim as a third dimension. This allows the projection to extend beyond the opaque surface boundary into the space behind it, creating genuine depth and volume without occupying physical show space, thereby resolving the contradiction between 3-D effect quality and space requirements
3Shape
If projection characteristics are not adjusted for different surfaces, then the system is simpler to operate, but the visual authenticity of the 3-D object is reduced
Solution Approach 1:
The system applies different projection characteristics to different regions of the display surface. The opaque surface receives projections optimized for sharpness and detail, while the translucent scrim receives projections optimized for smooth transitions and depth. This local differentiation of projection parameters enhances visual authenticity by matching the optical properties of each surface, and the complexity is managed through automated parameter adjustment rather than manual control
