Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection systems often fail to provide sufficient color saturation and uniformity, leading to undesirable appearances when projectors malfunction, particularly in theme park attractions where consistent imagery is crucial for artistic effect.
Innovation Solution
A projection system incorporating active materials like nanoparticles, photochromic, and thermochromic materials on the projection surface, activated by secondary light sources to enhance image characteristics and provide a backup image when the primary projector fails, ensuring continuous and aesthetically pleasing visuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional projectors are used to project images, then the projection system is simple and easy to operate, but the color saturation and brightness are insufficient
Solution Approach 1:
The projection surface applies a composite coat containing multiple types of active materials (fluorescent materials, phosphorescent materials, photochromic materials, thermochromic materials, and nanoparticles) that work together to enhance color saturation and brightness when activated by light, resolving the contradiction between simple projector design and enhanced image quality
Solution Approach 2:
The system changes the optical parameters of the projection surface by using active materials that alter their properties when exposed to light, transforming the surface from a passive reflective surface to an active light-enhancing surface that improves color saturation and brightness without requiring a more complex projector
2Reliability
If a single projector is used, then the device complexity is low, but the reliability is poor when the projector fails
Solution Approach 1:
The system performs preliminary action by pre-applying the active material coat to the projection surface before operation. This ensures that when the projector fails or is turned off, the surface already contains the necessary materials to generate imagery, providing automatic backup without requiring complex redundant projector systems
Solution Approach 2:
The active material coat acts as an intermediary between the projector and the final image display. When the projector provides light, the coat enhances it; when the projector fails, the coat can still generate imagery using ambient or alternative light sources, providing a buffer that maintains projection continuity without requiring duplicate projectors
3Use of energy by moving object
If the projector is turned off to save energy, then the energy consumption is reduced, but the appearance becomes undesirable
Solution Approach 1:
The active material coat undergoes color changes when exposed to different light conditions. When the projector is off, the coat can still respond to ambient light or alternative sources to maintain a visually acceptable appearance, eliminating the need to keep the projector running solely for aesthetic purposes and thus reducing energy consumption

AI summary
The present disclosure includes a projection system for enhancing color saturation and contrast for a projected image. The projection surface includes a coat containing active materials and the projection system includes a first light source emitting light onto the surface and defining a first image on the surface and a second light source emitting light onto the surface and activating the active materials within the transparent coat to emit visible light of one or more wavelengths. The first light source defines the first image and the visible light emitted from the active materials enhances one or more characteristics of the first image. In another embodiment, the second light source may be activated when the first light source fails to define a backup or static image that may be different or the same as the image produced by the first light source.
