Beam Framing System for Automated Luminaire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated luminaires lack a simplified mechanism for providing soft edged framing or masking, which is necessary for soft edged or wash light systems commonly used in entertainment applications, as current systems are complex and expensive to manufacture.
Innovation Solution
A beam framing system that includes adjustable framing shutters with motorized control, allowing for independent movement and rotation of blades to achieve soft edged occlusion, integrated with a diffusion filter for homogenization and increased output angle range, and a Fresnel lens with enhanced facets for adjustable beam focus and zoom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional framing shutter systems with multiple motorized blades are used, then beam masking and shaping capability is improved, but device complexity and manufacturing cost increase substantially
Solution Approach 1:
The patent extracts the complex multi-motor blade system and replaces it with a single rotating framing shutter assembly. This removes unnecessary complexity while retaining the essential beam masking function through a simplified mechanical structure that rotates to achieve framing effects.
Solution Approach 2:
The patent merges multiple independent blade control systems into a single integrated framing shutter assembly that rotates as one unit. This combines the functionality of multiple motorized blades into a single mechanism, reducing device complexity while maintaining beam shaping capability.
2Adaptability or versatility
If multiple motorized blades with individual angular control are implemented, then beam shaping versatility is improved, but weight and cost increase substantially
Solution Approach 1:
The patent combines multiple independent blade mechanisms into a single rotating framing shutter assembly. This consolidation dramatically reduces the moving weight while maintaining the ability to shape and frame the beam through rotational positioning of the integrated structure.
Solution Approach 2:
The single rotating framing shutter assembly performs multiple functions that would traditionally require separate motorized blades. By making this single component multi-functional, the patent reduces overall weight while maintaining comprehensive beam shaping capability.
3Adaptability or versatility
If complex mechanisms with multiple selectable edges per blade are used, then edge shape options are improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent removes the complex mechanism requiring multiple selectable edges per blade. Instead, it uses a single rotating framing shutter assembly where different edge shapes are achieved through the rotation and positioning of the integrated structure, dramatically simplifying manufacturing.
Solution Approach 2:
Rather than having multiple edges on each blade that can be selected, the patent inverts the approach by having a single rotating assembly where the edge shape is determined by the orientation and position of the structure during rotation. This reverses the traditional design logic and simplifies manufacturing.
