AI Technical Summary

Technical Problem

Existing pyrotechnic devices suffer from inconsistencies in the height and spread of pyrotechnic stars due to unstable pressure changes during ignition, leading to unpredictable visual effects and potential safety risks.

Method used

A pyrotechnic device with a monolithic housing comprising a sidewall and bottom wall, a constant cavity width increase, and controlled gas flow features to stabilize gas expansion, along with a cap to protect components and ensure consistent ejection of pyrotechnic stars.

Benefits of technology

The solution provides improved consistency in pyrotechnic star dispersion and reduced environmental impact by minimizing turbulence and enhancing safety through a one-piece housing design and controlled gas flow, ensuring uniform launch height and visual effects.
