Rotatable Light Forming Device for Continuous Beam Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light effect systems for forming light beams in light fixtures are limited by mechanical restrictions, such as a frame support that can only rotate approximately 45 degrees and shutter blades with limited movement, making it time-consuming to frame desired areas, especially in large setups, and often require physical movement and reprogramming of light fixtures.
Innovation Solution
A light effect system with a framing system that includes a base support and a frame support with shutter blades and actuators, where the frame support can rotate continuously more than 360 degrees, and rotatable electric connecting means for transferring power and control signals, allowing for unlimited rotation and adjustment of the light beam shape without physical movement of the light fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame support is limited to approximately 45 degrees rotation due to mechanical restrictions, then the mechanical structure remains simple, but the light beam framing capability is insufficient and requires physical movement of the light fixture which is time-consuming
Solution Approach 1:
The frame support is transformed from a statically limited structure to a dynamically rotatable one. The patent implements a continuous rotation mechanism that allows the frame support to rotate more than 360 degrees around the light beam axis, enabling the shutter blades to frame any desired area without physically moving the entire light fixture. This dynamic capability resolves the contradiction by providing unlimited framing adaptability while eliminating time-consuming physical repositioning.
2Adaptability or versatility
If the frame support can rotate continuously more than 360 degrees, then the light beam can be framed in any direction without physical movement, but the mechanical complexity increases
Solution Approach 1:
The patent replaces complex mechanical rotation mechanisms with an electrical field-based solution. Instead of using traditional mechanical gears, belts, or linkages to achieve continuous rotation, the invention employs electric fields to actuate the frame support and shutter blades. This substitution eliminates the need for complex mechanical transmission components while enabling smooth, continuous rotation beyond 360 degrees, thus achieving high framing flexibility without proportionally increasing mechanical complexity.
3Manufacturing precision
If multiple components are required to shape the light beam, then the light beam can be precisely framed, but the device takes up a lot of space and cannot be integrated inside the light fixture housing
Solution Approach 1:
The patent implements a nested configuration where the frame support and shutter blades are positioned concentrically around the light beam path. The frame support rotates around the central light beam axis, and the shutter blades are arranged radially within the same cylindrical volume. This nested arrangement allows multiple light beam shaping components to occupy minimal space while maintaining full functional capability for precise framing, enabling complete integration within the light fixture housing.
Solution Approach 2:
The patent transitions from a linear arrangement of light beam shaping components to a radial/dimensional arrangement around the light beam axis. Instead of placing components in sequence along the beam path (which would require significant length), the invention positions the frame support and shutter blades in a radial configuration that can rotate around the beam. This dimensional change from linear to radial arrangement dramatically reduces the volume required while maintaining precise light beam shaping capability.
