Cyclorama Panel Curvature for Uniform Light and Sound Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cycloramas in photography and film production often suffer from uneven lighting and sound amplification due to the focusing of light and sound by curved panels, creating shadows and uneven sound propagation along specific sight lines.
Innovation Solution
The use of modular panel members with concavo-convex designs featuring integrally-formed side portions and intermediate portions, where the radii of curvature in the Y-Z plane differ from those in the X-Y plane, to uniformly diffuse light and sound, reducing shadows and sound amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If curved panels are used in cyclorama corners, then the appearance of uninterrupted space is improved, but sound focusing and amplification in particular directions occurs
Solution Approach 1:
The panel employs different radii of curvature in different regions: a first radius of curvature in the corner region and a second radius of curvature in the non-corner regions, where the second radius is greater than the first. This local variation in curvature distributes sound reflection more evenly across different directions, preventing sound focusing and amplification in particular directions while preserving the curved panel's ability to create an uninterrupted space appearance.
2Shape
If curved panels are used in cyclorama corners, then the appearance of uninterrupted space is improved, but light reflection creates shadows or uneven lighting
Solution Approach 1:
The panel employs different radii of curvature in different regions: a first radius of curvature in the corner region and a second radius of curvature in the non-corner regions, where the second radius is greater than the first. This local variation in curvature distributes light reflection more evenly across different directions, reducing shadows and achieving more uniform lighting while preserving the curved panel's ability to create an uninterrupted space appearance.
3Ease of operation
If modular panel members are used, then assembly and disassembly is simplified, but manufacturing complexity increases
Solution Approach 1:
The cyclorama structure is divided into multiple modular panel members, each with standardized connection interfaces. The panels can be independently manufactured with varying dimensions but consistent connection mechanisms, allowing for simplified assembly and disassembly while managing manufacturing complexity through standardization of key components.
Solution Approach 2:
The panel members incorporate universal connection mechanisms that can accommodate different panel sizes and configurations. The standardized interfaces and attachment systems allow the same connection hardware to work across various panel types, simplifying assembly procedures while the modular design enables flexibility in creating different cyclorama configurations.

AI summary
A panel member for a cyclorama includes a concavo-convex body having integrally-formed first and second side portions with an intermediate portion therebetween. The first side portion, the second side portion, and the intermediate portion have a radius of curvature in a Y-Z plane, and the first and second side portions have a radius of curvature in an X-Y plane that is different from the radius of curvature in the Y-Z plane to uniformly reflect or diffuse sound and light incident on the panel member.
