Solution Overview

Problem

Traditional candles pose risks of fire and air pollution due to flame and combustion, limiting their use in certain environments and requiring a safer, flameless alternative that mimics the swaying flame effect.

Innovation Solution

An electric flameless candle design featuring a translucent shell, light emitting diodes, an electromagnetic sway module with a metal bar and coil, and a circuit board that creates a magnetic field to sway the shell, simulating a candle flame without actual fire or pollution, using a copper coil, iron core, and iron bar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a traditional candle with flame is used, then the swaying flame effect and romantic atmosphere are achieved, but fire risk and air pollution occur

Engineering Contradiction:

Improveswaying flame effectVSAvoidfire risk and air pollution

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical combustion system (flame) with an electromagnetic system. An electromagnetic sway module generates a magnetic field that causes a metal bar to sway, which in turn moves a translucent shell to simulate flame motion. This substitution eliminates fire and combustion gases while maintaining the visual effect of a swaying flame.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a visual copy of the flame effect using light and motion rather than actual fire. The translucent shell diffracts light from LEDs to simulate flame appearance, while the electromagnetic sway module replicates the natural swaying motion of a real flame without using combustion.

Inventive Principle:

Principle #26Copying

2Illumination intensity

If a traditional candle is used, then the lighting effect and romantic atmosphere are provided, but safety risks in flammable environments increase

Engineering Contradiction:

Improvelighting effectVSAvoidsafety in flammable environments

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent replaces the flame-based lighting system with an LED-based electromagnetic system. LEDs provide the lighting effect without producing open flames, making the device safe for use in flammable environments while maintaining the visual characteristics of a candle.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If an electromagnetic sway module is added to create flame swaying effect, then the realistic flame motion is achieved, but device complexity increases

Engineering Contradiction:

Improveflame swaying effectVSAvoiddevice structure

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent divides the sway mechanism into separate functional components: an electromagnetic sway module that generates magnetic fields, a metal bar that responds to the magnetic fields, and a translucent shell that translates the metal bar's motion into flame-like movement. This segmentation allows each component to be optimized independently while working together to create the overall flame effect.

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The electric flameless candle effectively replicates the swaying flame effect of traditional candles without fire or air pollution risks, providing a safer and environmentally friendly lighting solution.

Implementation Method 1

When the circuit board provides a pulse current to the metal coil, the energizing metal coil lets the metal core become magnetic, and a magnetic field is formed between the metal bar and the metal core

Methodology Applied

Scientific EffectElectromagnetic induction: Electromagnetic Induction

Implementation Method 2

the translucent shell includes a translucent shell base... the translucent shell diffracts the light from the light emitting unit, so the translucent shell provides the lighting effect of the candle flame

Methodology Applied

Scientific EffectDiffraction: Diffraction
