Firework Holder Tray with Inverted Legs and Shape-Matched Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for consumer fireworks lack safety and stability, as loose fireworks tend to fall over during ignition, potentially causing unintended detonations of adjacent fireworks.
Innovation Solution
A holder with a tray and legs that positions fireworks upside-down, with openings matching the diameter and shape of fireworks, ensuring they are securely supported and easy to ignite individually, and includes clamping means for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fireworks are placed loosely in traditional packaging, then the packaging is simple and easy to manufacture, but the fireworks tend to fall over during ignition causing safety hazards
Solution Approach 1:
The holder is designed to be placed upside-down on the surface, with the tray inverted and legs extending upward. This inversion allows the fireworks to be positioned securely on the underside of the tray, preventing them from falling over during ignition while maintaining manufacturing simplicity.
Solution Approach 2:
The holder is divided into separate components: a tray with openings and legs that can be assembled after packaging. This segmentation allows the holder to be compact during transport and easily assembled by the consumer, providing stability without adding excessive complexity to the packaging structure.
2Volume of stationary object
If multiple fireworks are placed close together for compact packaging, then space utilization is improved, but the risk of spontaneous detonation of adjacent fireworks increases
Solution Approach 1:
The tray is provided with multiple separate openings, each designed to hold a single firework. This segmentation physically isolates each firework within its own opening, preventing accidental detonation of adjacent fireworks while maintaining compact packaging. The legs provide additional spacing and stability between fireworks.
Solution Approach 2:
The holder structure acts as an intermediary between the fireworks and the packaging environment. It provides a stable platform that positions fireworks securely in place, preventing them from falling over or contacting each other accidentally, thus reducing the risk of spontaneous detonation while enabling compact arrangement.
3Reliability
If the holder is designed with precise openings matching fireworks dimensions, then fireworks stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The openings in the tray are designed with dimensions and shapes that correspond to the width of standard fireworks. By optimizing these parameters within reasonable tolerances, the holder provides stable positioning without requiring excessive manufacturing precision. The upside-down configuration and leg structure compensate for minor dimensional variations.
4Volume of stationary object
If the holder is assembled after packaging, then space utilization and transport efficiency are improved, but ease of operation decreases
Solution Approach 1:
The holder is designed as separable components (tray and legs) that can be easily assembled after packaging. The legs are designed to attach to the underside of the tray, creating a stable structure. This segmentation allows for compact packaging during transport while enabling simple assembly by the consumer at the point of use.

AI summary
There is disclosed a holder (1) for consumer fireworks (4). The holder comprises a tray (6) provided with legs (3), which extends above a surface after being installed on said legs, which tray is provided with at least one opening (7). The opening is configured to enclose consumer fireworks to be placed on said surface and has a diameter and shape that correspond to the width of the fireworks. This results in a safe, lightweight holder for the ornamental consumer fireworks which is easy to manufacture at low cost. Where loosely placed fireworks cakes exhibit a greater tendency to fall over upon being ignited during festivities, this problem is eliminated by the simple holder according to the invention.
