Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative combustion devices take a long time to fill an indoor space with fragrance, as they rely on electric heating which is inefficient for rapid fragrance emission.
Innovation Solution
A combustion device comprising a burner with a fragrance diffuser, where the burner includes a fuel container and a wick, and the fragrance diffuser has a support and holder to hold a fragrance substance, with a design that allows for efficient heat transfer and fragrance particle dispersion through penetrating holes, enabling rapid fragrance emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electric heating is used to heat the fragrance capsule, then the device structure is simple, but it takes a very long time for the entire indoor space to be full of fragrance
Solution Approach 1:
The patent replaces the electric heating system with a combustion-based thermal system. The burner generates heat through combustion of fuel (candle or liquid fuel), which directly heats the fragrance capsule without requiring electrical components. This substitution resolves the contradiction by providing rapid heat generation (improving productivity) while maintaining relatively simple device structure (though adding combustion components).
Solution Approach 2:
The patent utilizes phase transition of the fragrance material from solid to liquid to gas. The fragrance capsule contains solid fragrance material that melts when heated by the combustion source, then evaporates to release fragrance into the air. This phase transition mechanism enables rapid fragrance emission compared to electric heating, resolving the productivity issue while keeping the overall device structure simple.
2Adaptability or versatility
If a fragrance capsule is placed in the burner, then the device can emit fragrance, but it takes a very long time to fill the indoor space with fragrance
Solution Approach 1:
The patent replaces electric heating with combustion heating to accelerate the fragrance emission process. The combustion source generates higher temperatures more quickly than electric heaters, causing faster melting and evaporation of the fragrance material, thus reducing the time required to fill the indoor space with fragrance.
Solution Approach 2:
The fragrance capsule is pre-designed with a structure that facilitates rapid heating and fragrance release. The capsule contains solid fragrance material positioned to maximize surface area exposure to heat, and includes pathways for efficient fragrance diffusion. This preliminary preparation enables the fragrance to be released quickly once heating begins, reducing the time loss.
3Stability of the object's composition
If the inner wall is arranged around the narrow portion and abutted against the outer end face, then the structural stability is improved, but the fragrance diffusion space is reduced
Solution Approach 1:
The support structure is segmented into distinct functional zones: the inner wall provides structural support and stability around the combustion area, while the outer wall creates a separate diffusion chamber. This segmentation allows the inner wall to be positioned close to the narrow portion for stability without significantly compromising the overall fragrance diffusion volume in the outer region.
Solution Approach 2:
The support structure utilizes vertical dimensionality to resolve the space conflict. The inner wall extends vertically around the narrow portion to provide stability, while the fragrance diffusion occurs in the horizontal and upper vertical spaces between the inner and outer walls. This dimensional arrangement allows structural support without significantly reducing the fragrance diffusion volume.

AI summary
A combustion device (10) comprises a burner (20) and a fragrance diffuser (30). The burner (20) is provided with a top end (21) having a combustion portion (22). The fragrance diffuser (30) includes a support (31) and a holder (32) adapted to hold a fragrance substance. The support (31) is disposed on the top end (21) and has an inner wall (311) and an outer wall (312). The inner wall (311) is arranged around the combustion portion (22), and the outer wall (312) is arranged around the inner wall (311). A holding space (313) is formed between the inner wall (311) and the outer wall (312). The holder (32) is disposed in the holding space (313). Thus, the combustion device (10) is not only for decorative purpose, but also able to emit fragrance. Further, the fragrance diffuser (30) can function as a windshield of the burner (20).
