Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing effects wheel assemblies for stage light fixtures face difficulties in easy coupling and alignment due to confined spaces and reliance on magnetic clamping, which complicates the interchangeability and correct alignment of the effects wheel with the supporting device.
Innovation Solution
The effects wheel assembly features a supporting device with elastically operated jaws that releasably clamp the effects wheel, ensuring proper alignment and easy coupling by inserting the hub between the jaws, facilitating secure and efficient attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If magnetic fastening device is used to connect supporting device and effects wheel, then interchangeability is improved, but coupling difficulty increases due to confined space and misalignment issues
Solution Approach 1:
A magnetic alignment ring is introduced as an intermediary component between the supporting device and effects wheel. This ring contains magnetic elements arranged in a specific pattern that creates a magnetic field to guide and align the effects wheel with the supporting device during coupling, eliminating the need for trial-and-error alignment in confined spaces
Solution Approach 2:
The magnetic alignment ring pre-establishes the correct alignment position through magnetic attraction before the operator completes the coupling. The magnetic field guides the effects wheel into proper position automatically, performing the alignment action beforehand rather than requiring manual adjustment during coupling
2Strength
If magnetic force clamping is used, then attachment security is improved, but alignment precision deteriorates due to lack of mechanical centering
Solution Approach 1:
The solution merges two different fastening mechanisms: magnetic clamping for secure attachment and mechanical centering for precise alignment. The magnetic alignment ring provides both magnetic attraction for security and geometric features for mechanical centering, combining the advantages of both approaches in a single integrated system
3Manufacturing precision
If trial and error method is used for centering, then alignment is achieved, but time consumption increases significantly
Solution Approach 1:
The magnetic alignment ring serves as a mediator that transforms the trial-and-error centering process into an automatic alignment process. The magnetic field and geometric features of the ring guide the effects wheel into correct position immediately upon approach, eliminating the need for repeated attempts and significantly reducing coupling time

AI summary
An effects wheel assembly for a light fixture, in particular a stage light fixture, suitable to generate a light beam, has a supporting device which rotates about a first axis; and an effects wheel having a hub, which extends about a second axis, and an effects portion, which extends about the hub and is suitable to generate optical effects when intercepting the light beam; the supporting device and the effects wheel being selectively connectable to each other by means of jaws elastically operated to clamp the effects wheel when the hub is inserted between the jaws.
