Flameless Candle Wax Insert Light Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flameless candles constructed with plastic shells often fail to diffuse light effectively, creating unwanted shadows and a poor illusion of a traditional candle, despite the durability and precision of plastic materials.
Innovation Solution
A flameless candle design featuring a waxen shell with a hollow interior housing an LED lamp and a waxen insert with a shading wall, allowing for controlled light diffusion and improved illumination characteristics, including the option for different thickness and opacity levels between the shell and insert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic shell is used for the flameless candle, then the durability and manufacturing precision are improved, but the light diffusion quality deteriorates
Solution Approach 1:
The patent applies composite materials by combining plastic and waxen materials in a single candle structure. The shell is made of plastic for durability and precision, while the insert is made of waxen material for optimal light diffusion. This composite approach allows each material to contribute its superior properties, resolving the contradiction between durability and light diffusion quality.
Solution Approach 2:
The candle is segmented into two distinct parts: an outer plastic shell and an inner waxen insert. This segmentation allows each component to be optimized for its specific function - the plastic shell provides structural integrity and durability, while the waxen insert provides superior light diffusion characteristics, thereby resolving the contradiction between these two properties.
2Manufacturing precision
If a plastic shell is used for the flameless candle, then the manufacturing precision is improved, but the light diffusion quality deteriorates

The shell is made of plastic for durability and precision, while the insert is made of waxen material for optimal light diffusion.

This segmentation allows each component to be optimized for its specific function - the plastic shell provides structural integrity and durability, while the waxen insert provides superior light diffusion characteristics, thereby resolving the contradiction between these two properties.
3Ease of manufacture
If a uniform waxen material is used for both shell and insert, then the manufacturing simplicity is improved, but the light diffusion control deteriorates
Solution Approach 1:
The patent applies local quality by using different materials for different parts of the candle. The outer shell uses plastic material while the inner insert uses waxen material. This allows each region to have the optimal properties for its function - the plastic shell for structural integrity and the waxen insert for light diffusion control, thereby resolving the contradiction between manufacturing simplicity and light diffusion control.
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 design enhances the light diffusion and illumination quality, providing a more natural and desirable lighting effect that mimics a traditional candle without sacrificing the benefits of plastic construction, such as durability and precision.
Implementation Method 1
A light source may generate light that emanates through the shell
Implementation Method 2
it does not tend to diffuse light as one may expect from a traditional flamed candle

AI summary
A flameless candle includes a shell that has a sidewall and a hollow interior region. The sidewall can be made of a waxen material. The sidewall has a thickness and opacity. The shell also has a hollow interior region within the sidewall. A lamp (for example, LED) may be housed within the hollow interior region. The flameless candle also includes an insert. The insert can be made of a waxen material that may have different properties from the material of the sidewall. The insert is positioned in a top area of the hollow interior region. The insert includes a shading wall that has a thickness and opacity. The thickness of the sidewall may be different than the thickness of the shading wall. As another option, the opacity of the sidewall may be different from the opacity of the shading wall.
