Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional fireworks are used for aerial displays, then visual entertainment is provided, but fire hazards and smoke emission occur
Solution Approach 1:
The patent replaces the chemical combustion system of conventional fireworks with a pneumatic propulsion system. Compressed air is used to launch the aerial display device, eliminating the need for explosive propellants. The visual effects are achieved through LED lighting systems rather than pyrotechnic compositions, thereby eliminating fire hazards and smoke emission while maintaining visual entertainment quality
Solution Approach 2:
The patent employs compressed air (pneumatics) as the propulsion mechanism to launch the aerial display device. A compressed air reservoir and valve system provide controlled gas pressure to propel the device upward, replacing the chemical explosive system entirely. This pneumatic approach eliminates fire hazards while achieving the necessary launch performance
2Illumination intensity
If conventional fireworks are used for aerial displays, then visual effects are produced, but loud noises are generated
Solution Approach 1:
The patent replaces the explosive combustion system that generates loud noises with a pneumatic propulsion system and LED lighting system. The compressed air launch is significantly quieter than explosive propellants, and the LED visual effects produce no noise at all, thereby eliminating the harmful noise factor while maintaining visual entertainment quality
3Illumination intensity
If pyrotechnic devices are used, then self-contained exothermic reactions produce light and effects, but environmental pollution and health risks increase
Solution Approach 1:
The patent replaces the exothermic chemical reaction system with a pneumatic propulsion system and electrical LED lighting system. The compressed air launch eliminates chemical propellants, and the LED system provides light without combustion. This substitution eliminates environmental pollution and health risks associated with inhaling smoke and chemical residues while maintaining light production and visual effects
Solution Approach 2:
The patent uses compressed air (inert atmosphere) as the propulsion medium instead of flammable chemical propellants. The LED lighting system operates without combustion, creating a clean, pollution-free environment. This approach eliminates harmful emissions and health risks while providing the necessary light and visual effects
4Speed
If aerial fireworks are launched with lifting charges, then shells reach desired altitude, but fire danger is elevated
Solution Approach 1:
The patent uses a compressed air reservoir and pneumatic valve system to launch the aerial display device. The compressed air provides the necessary pressure and velocity to reach desired altitudes without using flammable lifting charges. This pneumatic launch system eliminates fire danger while achieving the required launch performance
Solution Approach 2:
The patent replaces the chemical lifting charge system with a pneumatic propulsion system. The compressed air mechanism provides the same launch function without the fire hazards associated with explosive propellants, thereby eliminating fire danger while maintaining the ability to reach desired altitudes
