Solution Overview

Problem

Existing fireworks face challenges in reliable ignition due to difficult access of the ignition fuse, which increases user risk and complicates connections with additional fireworks.

Innovation Solution

A firework design featuring a positioning means that allows the ignition means to be mechanically connected and positioned at a distance from the receiving part, enabling easier and safer ignition, as well as reliable connection with other fireworks, through a pivotable and securely attachable mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the fuse is arranged on the firework surface for easy access, then ignition ease is improved, but structural stability deteriorates

Engineering Contradiction:
Improveignition easeVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The firework is divided into separate functional modules: a stable receiving part for the pyrotechnic effect and a separate positioning means for the ignition device. This segmentation allows the ignition means to be positioned independently without compromising the structural integrity of the main firework body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A positioning means acts as an intermediary component between the receiving part and the ignition means. This mediator enables the ignition device to be positioned at an optimal distance and angle for easy access while maintaining a stable connection to the firework structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the ignition means is positioned close to the receiving part, then structural simplicity is improved, but ignition safety deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidignition safety
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The ignition means is extracted from the immediate vicinity of the pyrotechnic effect and positioned at a distance through the positioning means. This extraction reduces the harmful thermal and mechanical influence on the ignition device while maintaining structural connection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the fuse is positioned for easy user access, then ignition reliability is improved, but connection reliability with additional fireworks deteriorates

Engineering Contradiction:
Improveignition reliabilityVSAvoidconnection reliability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The positioning means serves multiple functions: it positions the ignition means for easy user access, maintains structural stability, and provides connection interfaces for linking additional fireworks. This multi-functionality resolves the contradiction between ignition reliability and connection versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
