Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional frame animation techniques require multiple frames to achieve smooth movement, which can be limiting in creating dynamic and varied animated effects, especially when applied to moving lights like gobos, where the ability to display multiple images at different orientations is restricted.
Innovation Solution
A gobo system that combines multiple frame parts with different optical codings, utilizing an interference pattern that can rotate to reveal partial images, creating an animation sequence by selectively interfering with these frames, allowing for multiple animations from a single set of gobos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional frame animation techniques are used with multiple frames, then smooth movement can be achieved, but the ability to display multiple images at different orientations is restricted
Solution Approach 1:
The gobo is divided into multiple frame parts, each containing a different frame of the animation sequence. These segmented frames are arranged in a combined sectional frame structure, allowing selective interference to reveal individual frames or combinations of frames at different orientations, thereby achieving multiple images display capability while maintaining smooth animation transitions.
Solution Approach 2:
The patent introduces an additional dimension of orientation by arranging frames in a combined sectional frame that can be viewed at multiple orientations. The interference pattern interacts with these frames in three-dimensional space, allowing the same gobo to produce multiple different animation sequences depending on the viewing angle, thus overcoming the limitation of single-orientation display.
2Productivity
If multiple frame parts are combined into a single gobo, then multiple animations can be created from one set, but the device structure becomes more complex
Solution Approach 1:
Multiple frame parts representing different animation sequences are merged into a single combined sectional frame structure within one gobo. This merging allows a single gobo to contain and display multiple complete animation sequences by selectively interfering with different frame combinations, thereby increasing productivity without requiring multiple separate gobo sets.
Solution Approach 2:
The combined sectional frame structure serves multiple functions: it can display different animation sequences, support multiple orientations, and work with various interference patterns. This multi-functionality allows a single gobo design to replace what would traditionally require multiple specialized gobo sets, simplifying the overall system while increasing versatility.
3Adaptability or versatility
If frames are arranged in combined sectional frame with different optical codings, then selective interference can reveal partial images, but manufacturing precision requirements increase
Solution Approach 1:
Different regions of the combined sectional frame are assigned different optical codings tailored to their specific function. Each frame part or sectional area has optimized optical properties (such as transparency, opacity, or refractive characteristics) that enable selective interference to reveal specific frames or partial images. This localized optimization achieves the desired versatility while managing manufacturing complexity through region-specific design.

AI summary
An automated luminaire, that combines outputs from two different gobo assemblies. A first gobo assembly has a combined sectional frame that is a combination of a plurality of different frames, each frame representing a different individual image. The combined sectional frame includes different optical codings for the different views of the image. A second gobo assembly includes an interference pattern which is coded at different orientations to allow only one of the images to be seen at any of a plurality of different orientations of the interference pattern. At least one of the first and second gobo assemblies being rotatable, and commanded by the commands received by the computer to different orientations relative to one another, to allow the only one of the images to be seen at anyone time.
