Portable motion picture theater
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional movie theaters face issues with suboptimal viewing experiences due to seat placement, screen size, and frame rate, leading to artifacts like blurring, strobing, and eyestrain, especially in giant screen formats, which are costly and inefficient in terms of space and construction.
Innovation Solution
A portable theater design featuring a hemispherically curved projection screen and high frame rate projection at 120 frames per second, combined with prefabricated modular components, reduces eyestrain and costs by providing a wider field of view and immersive 3D experience without the drawbacks of conventional systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is increased to provide a wider field of view, then the viewing experience is improved, but the construction cost and space requirements increase significantly
Solution Approach 1:
The patent employs a curved (hemispherical or toroidal) projection screen instead of a flat screen. This curvature allows the screen to wrap around the viewer's field of view, providing a wider angular coverage (up to 180 degrees or more) without requiring a proportionally larger physical screen area. The curved geometry efficiently distributes the projected image across a broader visual field, achieving immersive viewing experience with reduced material requirements compared to a flat screen of equivalent visual coverage.
2Object-generated harmful factors
If the frame rate is increased to 120 fps to eliminate strobing and judder, then the motion smoothness is improved, but the energy consumption and device complexity increase
Solution Approach 1:
The patent implements a high frame rate projection system operating at 120 frames per second (or higher), significantly exceeding the conventional 24 fps standard. This parameter change in temporal frequency eliminates the persistence of vision artifacts (strobing, judder, and flicker) that occur at lower frame rates, particularly noticeable during camera motion or subject movement in the projected content. The high frame rate ensures that each frame is displayed long enough to be fully perceived before the next frame begins, creating seamless motion without visible transitions or artifacts.
3Use of energy by moving object
If conventional 24 fps projection is used, then the energy consumption is lower, but the viewing experience deteriorates due to persistence of vision artifacts and strobing
Solution Approach 1:

4Area of stationary object
If a hemispherically curved screen is used to expand field of view, then the immersive experience is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
