Solution Overview

Problem

Existing pyrotechnic devices for creating luminescent designs require significant amounts of inflammable powder for lighting cylinders, making them fragile, prone to humidity damage, and complex to produce.

Innovation Solution

A pyrotechnic device with a box-shaped element featuring a burning surface and rising conduits to guide the flame towards the upper surface, eliminating the need for a traditional inflammable material lighting cylinder, using a modest quantity of powder for lighting and incorporating a cylindrical base with grooves to form conduits for the flame, which can be reused.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional lighting cylinder made of compressed inflammable powder is used, then the candle can be lit, but the device becomes fragile and prone to humidity damage

Engineering Contradiction:
Improvedurability of lighting cylinderVSAvoidcomplexity of producing lighting cylinder
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the traditional lighting cylinder made of compressed inflammable powder from the device. Instead, it uses a rigid container that can be reused, eliminating the fragile and humidity-sensitive powder cylinder while simplifying production processes.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a lighting cylinder of compressed powder is used, then the candle can be lit, but a significant quantity of inflammable powder is required

Engineering Contradiction:
Improvelighting effectivenessVSAvoidamount of inflammable powder
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and eliminates the need for large quantities of compressed inflammable powder by using a rigid container system that allows for more efficient and localized application of inflammable material, reducing overall consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If a rigid cylindrical container is used for moulding the lighting cylinder, then the structure is stable, but the container must be removed after use making the process complex

Engineering Contradiction:
Improvestructural stability of containerVSAvoidease of producing and reusing container
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent introduces a rigid container that is designed to be recovered and reused after the pyrotechnic composition is placed inside. This eliminates the need to discard the container after each use, simplifying the manufacturing process and reducing waste compared to traditional single-use moulds.

Inventive Principle:
Principle #34Discarding and recovering
