Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current candle wax formulations based on natural oils face issues such as cracking, air pocket formation, product shrinkage, and inconsistent burning characteristics, which affect flame height, burning time, and appearance, particularly with soybean-based waxes.
Innovation Solution
The method involves purifying natural oil wax compositions using a dissipation factor ranging from 0.0001 to 0.0600, measured at 70°C, to control purification and improve candle properties like rate of consumption and flame height, by incorporating filtration and bleaching processes to remove impurities like nickel and volatile compounds.

Engineering Contradiction Analysis
1Object-affected harmful factors
If natural oils are used as candle wax formulations, then environmental friendliness is improved, but product defects such as cracking, air pocket formation, and shrinkage occur
Solution Approach 1:
The patent applies preliminary action by performing purification processes (filtration, bleaching, deodorization) on natural oils before they are used as candle wax. This pre-treatment removes impurities that would otherwise cause cracking, air pockets, and shrinkage during candle manufacturing and burning, thereby maintaining both environmental friendliness and product reliability.
Solution Approach 2:
The patent utilizes parameter changes by monitoring and controlling the dissipation factor (a measure of dielectric loss) during purification processes. By adjusting purification parameters and measuring dissipation factor at specific temperatures, the patent optimizes the removal of impurities while preserving the desirable properties of natural oils for candle applications.
2Adaptability or versatility
If natural oils are used for candle wax, then natural material requirement is satisfied, but burning performance consistency deteriorates
Solution Approach 1:
The patent applies parameter changes by using dissipation factor measurements at controlled temperatures to monitor and standardize the purification process. This ensures consistent removal of impurities across different batches of natural oils, leading to uniform burning performance in the final candle products while maintaining the use of natural materials.
Solution Approach 2:
The patent implements feedback control by measuring the dissipation factor during purification and using this information to adjust processing conditions. This closed-loop approach ensures that natural oils achieve consistent purity levels, which directly translates to consistent burning performance in candles while preserving the natural material advantage.
3Manufacturing precision
If purification processes are applied to natural oil wax, then product quality is improved, but processing complexity increases
Solution Approach 1:
The patent replaces complex mechanical purification systems with a simplified approach based on dissipation factor measurements. By using this electrical/dielectric property as a purification indicator, the patent reduces the need for multiple complex mechanical filtration and separation steps, thereby improving product quality while reducing processing complexity.
Solution Approach 2:
The patent utilizes changes in dissipation factor (an electrical property analogous to color changes in visual detection) as an indicator of purification progress. This provides a simple, measurable parameter to monitor purification effectiveness without requiring complex analytical equipment, thus improving product quality while maintaining process simplicity.
