Solution Overview

Problem

Traditional electronic firework firing systems require a pair of wires with a clip-on fastener to ignite fuses, which is cumbersome and prone to errors.

Innovation Solution

An ignitor module is inserted into the firework, featuring a heating element and pyrotechnic material that ignites in response to electrical current, eliminating the need for fuses and talons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a clip-on style fastener with wires is used to ignite firework fuses, then electrical current can be delivered to ignite the firework, but the system becomes cumbersome and prone to errors

Engineering Contradiction:

Improveignition processVSAvoidfiring system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the electrical contacts, heating element, and pyrotechnic material into a single integrated ignitor module that is embedded directly into the firework body. This merging eliminates the need for separate wires and clip-on fasteners, reducing system complexity while maintaining the electrical ignition function. The module integrates multiple components (electrical contacts, heating element, pyrotechnic material) into one unified structure that simplifies the overall firing system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the mechanical clip-on fastener system with an embedded electrical module that directly contacts the firework body. Instead of using mechanical attachment methods (clips, fasteners, wires), the system uses direct electrical contacts integrated into the firework structure, eliminating the mechanical complexity of wire attachment while maintaining electrical current delivery for ignition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If traditional fuse and talon systems are used, then firework ignition can be achieved, but setup time increases and safety is reduced

Engineering Contradiction:

ImprovesafetyVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The ignitor module is pre-integrated into the firework body during manufacturing, with electrical contacts, heating elements, and pyrotechnic material already in position. This preliminary action eliminates the need for on-site assembly of wires and fasteners, reducing setup time while ensuring proper alignment and connection. The module is ready for immediate electrical connection and ignition, improving both safety and efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts the fuse and talon components from the ignition system, replacing them with an integrated electrical module. By removing the fuse and mechanical fastener elements, the system eliminates the associated setup time and safety risks related to fuse handling and mechanical attachment errors, while maintaining the essential ignition function through direct electrical heating of pyrotechnic material.
