Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Projectors face challenges in maintaining immersion and engagement due to background areas being exposed despite environmental corrections, leading to decreased user experience.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector performs correction functions to remove or change color of background portions, then the projection image can be corrected to adapt to surrounding environment, but light is still projected to the background area position causing it to be exposed and decreasing user immersion
Solution Approach 1:
The patent divides the projection system into two independent parts: a projection unit that outputs the projection image and a filtering unit (optical shutter) that selectively blocks light. This segmentation allows the correction function to modify the projection image while the filtering unit separately handles the blocking of background area light, resolving the contradiction by enabling both correction and background area blocking without interference.
Solution Approach 2:
The patent introduces an optical shutter as an intermediary component between the projection unit and the projection surface. This intermediary selectively blocks light corresponding to background areas while allowing light for corrected image areas to pass through, enabling the system to both correct the projection image and prevent background area exposure simultaneously.
2Reliability
If the projector outputs projection image at the projection surface, then the image can be displayed, but background areas remain exposed due to ambient illumination reducing immersion
Solution Approach 1:
The patent applies local quality by making different parts of the projection system have different functions: the projection unit outputs the entire projection image including background areas, while the optical shutter selectively blocks only the background area portions. This allows the system to maintain reliable projection output while locally preventing ambient illumination exposure at background areas, thereby improving immersion.
3Manufacturing precision
If the projector performs correction functions to adapt to projection environment, then the projection image quality improves, but the background area boundaries remain exposed causing inconvenience
Solution Approach 1:
The patent segments the projection system into a correction function that improves overall image quality and a separate filtering function that specifically addresses background area boundaries. The correction function enhances projection image quality by adapting to the projection environment, while the optical shutter simultaneously blocks exposed background boundaries, resolving the contradiction between image quality improvement and boundary exposure prevention.
