Coaxial Effect Wheel Assembly for Compact Stage Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stage lights with multiple effects require a larger space and greater safety distance between wheels, making them less compact and less efficient in terms of space utilization and effect generation.
Innovation Solution
A coaxially combined effect wheel assembly with a plurality of effect wheels, including at least one fixed and one rotatable wheel, where the wheels are driven to rotate coaxially by a transmission mechanism, allowing for overlapping effect sheets to create various stage effects while reducing the space and safety distance between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed wheel and rotatable wheel are installed independently, then each wheel can function independently, but greater safety distance and larger installation space are required
Solution Approach 1:
The patent merges the fixed wheel and rotatable wheel into a single integrated assembly where the rotatable wheel is positioned within the circular opening of the fixed wheel. This coaxial combination allows both wheels to function independently while occupying minimal space, eliminating the need for large safety distances between separately installed wheels.
Solution Approach 2:
The rotatable wheel is nested within the circular opening of the fixed wheel, creating a compact coaxial structure. This nesting arrangement allows the rotatable wheel to be positioned inside the space defined by the fixed wheel's opening, significantly reducing the overall installation footprint while maintaining functional independence.
2Adaptability or versatility
If fixed wheel and rotatable wheel are installed independently, then each wheel can operate separately, but larger space inside stage light is required
Solution Approach 1:
The patent combines multiple effect wheels into a single coaxial assembly that can be integrated within the existing internal space of stage lights. This merged structure provides multiple effects (fixed wheel patterns, rotatable wheel patterns, and their combinations) without requiring the larger volume that would be needed for separately installed wheels.
Solution Approach 2:
The patent transitions from a radial arrangement of independently installed wheels to a coaxial arrangement where wheels are stacked along the optical axis. This dimensional change from planar to axial stacking allows multiple wheels to occupy the same radial space, significantly reducing the internal volume requirement while maintaining multiple effect capabilities.
3Reliability
If effect wheels are arranged with greater safety distance, then operational safety is improved, but compactness and space utilization are reduced
Solution Approach 1:
The patent merges the safety function into the design itself by creating a coaxial arrangement where the rotatable wheel is positioned within the fixed wheel's circular opening. This integration eliminates the need for separate safety distances while maintaining operational safety through the structured coaxial configuration and controlled rotation mechanism.
Solution Approach 2:
The nested coaxial structure allows the rotatable wheel to be positioned inside the space defined by the fixed wheel's opening, eliminating the need for external safety distances. The nesting arrangement inherently provides safety through the controlled mechanical interaction within the compact structure, improving space utilization while maintaining operational safety.

AI summary
An effect wheel assembly for a stage light, comprising a plurality of effect wheels, each effect wheel having several effect sheets, a rotating shaft, and a transmission mechanism, the rotating shaft passing through an axle center of each effect wheel. The effect sheets of each of the effect wheels are correspondingly arranged to create various combined effects, and the transmission mechanism drives the rotating shaft to rotate in such a way that the effect wheels rotate coaxially. The effect sheets are driven by the transmission mechanism to rotate coaxially, during the rotating, the effects provided by the effect sheets will overlap such that a new stage effect is presented. The effect wheel assembly can not only meet the demand of multiple effects, but also meet the demand of a simplified structure, which is more practical.
