Solution Overview

Problem

Conventional fire knives pose safety risks due to their sharp blades, flammable materials, and potential for injury, especially when used by inexperienced users or in confined spaces, limiting their use and teaching opportunities.

Innovation Solution

A light emitting fire knife device that replicates the look and feel of traditional Samoan fire knives but uses LED lights instead of fire, providing a safe alternative with removable planar and cylindrical light emitting components, allowing for various light patterns and colors, and a design that mimics the weight and balance of traditional knives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fire knives with flammable materials and sharp blades are used, then authentic fire knife dancing performance is achieved, but safety risks and potential for injury increase significantly

Engineering Contradiction:

ImprovesafetyVSAvoidburns and injuries

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates a safe copy of the traditional fire knife by using LED lights embedded in the blade to replicate the visual appearance of fire without the actual flames. The light emitting components are positioned to mimic the glow and movement of fire, providing an authentic visual experience while eliminating burn hazards entirely

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the chemical combustion system (flammable materials and fire) with an electrical lighting system (LEDs and battery). This substitution maintains the visual effect of fire knife dancing while eliminating the harmful thermal and chemical aspects that cause injuries

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If traditional fire knives are used, then authentic performance experience is provided, but the sharp blade and flammable materials create injury risks

Engineering Contradiction:

Improveusability for inexperienced usersVSAvoidinjury risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The light emitting blade replicates the visual characteristics of a traditional fire knife without the dangerous properties, making it suitable for beginners and inexperienced users who need to learn techniques without facing the same safety risks as traditional practitioners

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent converts the harmful aspect of fire (visual spectacle) into a beneficial form (LED lighting) that provides the same performance value while eliminating the harmful thermal effects. The harm of fire is transformed into the benefit of safe, controllable light

Inventive Principle:

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

3Adaptability or versatility

If conventional fire knives are used in confined spaces, then traditional performance is maintained, but safety hazards are amplified due to proximity to people and surroundings

Engineering Contradiction:

Improveperformance location flexibilityVSAvoiddamage and injury risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

By replacing the fire-based system with an electrical lighting system, the patent enables performances in confined spaces and locations where open flames would be prohibited or dangerously close to spectators and surroundings

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The visual copy of fire through LED lighting allows performances to be conducted anywhere without the restrictions imposed by actual flames, providing location flexibility while maintaining the authentic appearance of traditional fire knife dancing

Inventive Principle:

Principle #26Copying
