Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to simulate explosive and pyrotechnic effects, such as fireworks and cannon shots, in a safe and repeatable manner that can be performed indoors and in various locations, as traditional pyrotechnics involve hazardous materials and are typically outdoor events.
Innovation Solution
A projection module that includes a light source, a diffractive optical element, and a motion assembly, which splits and converges light beams onto a projection surface to create dynamic and controlled light patterns, mimicking the effects of explosions or sparks, using a combination of diffractive optics and mechanical or electronic movement to vary the convergence point and orientation of the light beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional pyrotechnics are used to create explosive effects, then intensely bright naturally animated effects are achieved, but safety hazards and outdoor location requirements worsen
Solution Approach 1:
The patent creates optical copies of pyrotechnic effects using light projection instead of actual explosive materials. A light source projects patterns through diffractive optical elements to simulate sparks, fireworks, and explosion effects on a projection surface, eliminating hazardous materials while maintaining visual impact
Solution Approach 2:
The patent replaces the mechanical/chemical system of explosive materials with an optical system. Instead of using combustibles and explosives to create visual effects, the system uses light sources, lenses, and diffractive elements to project animated patterns that mimic pyrotechnic effects safely
2Illumination intensity
If traditional pyrotechnics are used for explosive effects, then visually impressive effects are achieved, but repeatability and indoor venue compatibility worsen
Solution Approach 1:
The system creates repeatable optical copies of pyrotechnic effects through controlled light projection. By using programmable light sources and diffractive optical elements, the same visual effects can be reproduced consistently in different locations and under different conditions, unlike actual pyrotechnics which vary with environmental factors
Solution Approach 2:
The patent employs dynamic control of the light projection system to create animated effects that simulate the natural movement of pyrotechnics. The motion assembly and control system adjust light beam orientation, convergence points, and projection patterns in real-time to reproduce the dynamic behavior of explosions and fireworks
