Multi-Wax Candle with Differential Melting Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scented candles with multiple waxes often release fragrances simultaneously due to waxes having the same melting points, which can lead to uneven scent release and potential softening of the wax, and lack effective odor control systems.
Innovation Solution
A scented candle design featuring at least two waxes with different melting points, where one wax with a higher melting point surrounds the wick and may include malodor control agents, allowing controlled fragrance release and odor abatement, with the option of varying fragrance concentrations and colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple waxes with the same melting point are used in a candle, then both scents are released simultaneously, but the fragrance release is uneven and the wax may soften
Solution Approach 1:
The patent applies parameter changes by using waxes with different melting points instead of the same melting point. This allows the lower melting point wax to melt first and release its fragrance, while the higher melting point wax maintains structural integrity and releases fragrance later, solving the problem of uneven scent release and wax softening.
Solution Approach 2:
The patent segments the candle into multiple wax layers with different melting points. The inner layer has a lower melting point for initial fragrance release, while the outer layer has a higher melting point for structural support and delayed fragrance release, enabling controlled sequential scent emission.
2Productivity
If fragrance material is added to wax, then scent is released, but the melting point of the wax is reduced and the wax softens
Solution Approach 1:
The patent divides the candle into two wax regions with different melting points. The inner wax contains fragrance material and has a lower melting point for active scent release, while the outer wax has a higher melting point to maintain structural integrity and resist softening, thus resolving the conflict between fragrance release and temperature stability.
3Object-affected harmful factors
If odor abatement agents are added to wax, then odors are controlled, but the wax composition becomes more complex
Solution Approach 1:
The patent merges odor abatement agents with the higher melting point wax composition. This combination allows the odor control function to be integrated into the structural wax layer, enabling simultaneous structural support and odor management without requiring separate complex systems.
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
Enables controlled and prolonged fragrance release, maintaining wax integrity and effectively managing odors through the use of distinct melting points and odor abatement materials, enhancing the candle-burning experience.
Implementation Method 1
at least two different wax materials with one such wax material having one melting point and at least one of the other wax materials having a second melting point
Implementation Method 2
One or both of the wax materials may include malodor control agents

AI summary
A scented candle includes at least two different wax materials with one of the materials having one melting point and at least one of the other wax materials having a second higher melting point. The wax having the higher melting point may include a malodor control agent or odor abatement substance or alternatively a fragrance that is different than the fragrance in the other wax materials in the candle. The second fragrance may also be at a much higher concentration than the fragrances in the other wax materials contained in the candle.
