Firework Holder with Magnetic Sensor for Predictable Image Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firework technologies fail to consistently display signs, symbols, or letters in the night sky with predeterminable orientation, often resulting in distorted or incomplete visuals due to rotational instability during ascent.
Innovation Solution
A firework holder with a molded body featuring a hollow hemisphere and guide rod, equipped with a sensor for determining the Earth's magnetic field, which ensures the firework rotates predictably around its longitudinal axis, allowing for precise orientation of the bursting charge and effect set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spherical or cylindrical firework bombs are used, then the firework can ascend and burst, but the spatial orientation of the effect image cannot be determined due to rotation around all three axes
Solution Approach 1:
The patent extracts and eliminates the rotational degrees of freedom by using a rocket-shaped firework holder with a longitudinal axis instead of a spherical or cylindrical bomb. This geometric change constrains rotation to only the longitudinal axis, removing the unwanted rotational movements around other axes and enabling predictable spatial orientation of the effect image.
Solution Approach 2:
The patent employs an asymmetric rocket-shaped firework holder with a defined longitudinal axis rather than a symmetric spherical or cylindrical shape. This asymmetry creates a preferred orientation during ascent, allowing the effect image to be displayed in a predetermined spatial orientation rather than rotating freely in all directions.
2Measurement precision
If firework rockets are used instead of ball and cylinder bombs, then rotation around longitudinal axis occurs, but vertical hearts are generated with varying width visibility and high speed ascent distorts effect images
Solution Approach 1:
The patent introduces an electronic control system with magnetic field sensors that dynamically adjust the ignition timing of the bursting charge based on the real-time rotational position of the firework during ascent. This dynamic control allows the system to compensate for rotation speed variations and ensure the effect image is displayed in the correct orientation regardless of ascent speed.
Solution Approach 2:
The patent employs magnetic field sensors to detect the rotational position of the firework holder during ascent and feeds this information back to an electronic control unit. Based on this feedback, the control unit precisely times the ignition of the bursting charge to occur at the optimal moment when the effect image will be displayed in the desired spatial orientation, thereby eliminating distortion.
3Stability of the object's composition
If ropes, chains and fabric panels are attached to ball and cylinder bombs, then degrees of freedom are limited, but effect images are still compressed, mirrored or only visible as vertical lines
Solution Approach 1:
The patent replaces the mechanical stabilization method (ropes, chains, and fabric panels) with an electronic control system using magnetic field sensors and controlled ignition timing. This substitution provides more precise control over the angular position of the effect image by electronically detecting rotational position and timing the burst accordingly, rather than relying on passive mechanical constraints that only limit but do not precisely control rotation.
4Reliability
If multiple heart bombs are fired to see a nice heart shape, then the correct heart shape may appear, but this requires very high effort and deformed hearts reduce the experience
Solution Approach 1:
The patent enables each individual firework to determine and display its own effect image in the correct spatial orientation through onboard magnetic field sensors and electronic control. This self-service capability eliminates the need to fire multiple fireworks to achieve a visible effect, as each firework independently ensures proper orientation, thereby reducing the number of launches required and eliminating deformed displays.
