Pyro-Cube Fireworks Modular Fuse Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fireworks ignition methods are complex and unsafe, as they require connecting multiple units with quick leads and plastic connectors, which can be hazardous and difficult to manage for achieving simultaneous and controlled ignition.
Innovation Solution
The Pyro-Cube fireworks system uses a configuration of male and female tubes with specific nozzle arrangements to connect and ignite multiple fireworks units sequentially, allowing for simple and safe ignition by linking fuses between stepped-cylinder and cylinder-shaped tubes, enabling diverse and stable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fireworks units are connected with quick leads and plastic connectors, then the fireworks can be ignited simultaneously, but the operation becomes complicated and unsafe
Solution Approach 1:
The patent merges the connector and the fuse into a single integrated structure. The female tube incorporates both the connection interface (receiving the male tube) and the fuse channel (guiding the fuse to the ignition point) as one unified component, eliminating the need for separate quick leads and plastic connectors. This integration simplifies the overall system while maintaining reliable and safe ignition.
Solution Approach 2:
The tube structure serves multiple functions simultaneously: it acts as a mechanical connector between units, a protective sheath for the fuse, and a guide channel for ignition. This multi-functionality reduces the number of components needed and simplifies the connection process while ensuring safe operation.
2Ease of operation
If fireworks units are connected in sequence, then the ignition becomes simpler and safer, but the entertainment effects become less diverse
Solution Approach 1:
The fireworks system is divided into independent modular units, each capable of being configured with different numbers and arrangements of firework tubes. This segmentation allows users to create diverse entertainment effects by combining different numbers of units (e.g., single unit, double unit, triple unit configurations) while maintaining simple sequential ignition through the standardized male-female tube connection system.

AI summary
A Pyro-Cube fireworks includes a plurality of fireworks units (10). Each of the fireworks units (10) includes a fuse (11), a plurality of fireworks launching tubes (12), at least one male tube (13), and at least one female tube (14). The fuse (11) connects with the female tube (14). The male tube (13) and the female tube (14) are configured in a rim of the fireworks units (10). The fuse (11) connects all fireworks launching tubes (12) with the male tube (13) from the female tube (14). The female tube (14) of one fireworks unit engages with the male tube (13) of another fireworks unit to connect the fuse (11) of the female tube (14) with the fuse (11) of the male tube (13) of adjacent fireworks unit. Only the fuse (11) on the female tube (14) of the first fireworks unit has to be ignited, and all fireworks units (10) are ignited in a sequence corresponding to the connecting sequence of the fuses (11). The igniting operation of the fireworks is simple and safe.
