Solution Overview

Problem

Pyrotechnic displays often emit hot embers or sparks that can ignite surrounding materials, posing a risk of fires in crowded venues and causing property damage or injury.

Innovation Solution

The Cold Spark Device (CSD) features a collector cavity with a sparkling device that generates 'cold sparks' contained within a display case, preventing ignition by using a collector and display case configuration that directs sparks away from surrounding materials, and includes a processing device for remote operation and various configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional pyrotechnic displays are used to provide entertainment, then visual effect and entertainment value are improved, but risk of ignition of surrounding materials increases

Engineering Contradiction:

Improvevisual effectVSAvoidignition risk

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful hot sparks into beneficial cold sparks by using a cold spark generator instead of traditional pyrotechnics. The device produces visual effects through cold spark particles that do not have sufficient temperature to ignite surrounding materials, thereby eliminating the ignition risk while maintaining the entertainment value.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent introduces a collector as an intermediary component that captures and contains the cold spark particles. The collector cavity and collector bottom opening work together to direct and contain the spark particles, preventing them from escaping and potentially causing harm, thus serving as a protective intermediary between the spark generator and the surrounding environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If collector cavity is designed to contain cold sparks, then safety is improved, but device complexity increases

Engineering Contradiction:

ImprovesafetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the device into distinct functional segments: a cold spark generator, a collector with cavity and bottom opening, and a base. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity. The collector is separated from the generator, allowing independent optimization of each part.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where the collector is positioned within the base, and the cold spark generator is contained within the collector cavity. This nesting arrangement consolidates multiple components into a compact integrated device, reducing overall complexity while maintaining safety functions.

Inventive Principle:

Principle #7Nested doll (Nesting)
