Candle Wick Storage Tank for Smoke-Free Flame Extinguishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combustion devices face difficulties in safely extinguishing flames due to air flow through the flow guiding mechanism, leading to potential scalding and carbonization of the candle wick, resulting in smoke and odor.
Innovation Solution
A combustion device design featuring a fuel tank assembly with a switch to control fuel flow, a pivotable filling seat, and a flow guiding assembly with pivotable shield members to manage flame size and extinguish the flame efficiently, reducing the risk of air contact with the candle wick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user blocks the opening on the shield to extinguish the flame, then the flame is extinguished, but air still flows through the flow guiding mechanism to contact the candle wick and prevent complete extinguishment
Solution Approach 1:
The patent extracts the candle wick from the flow guiding mechanism by providing a separate storage tank that isolates the wick from the air flow path. This allows the flame to be completely extinguished by blocking the opening, as the wick is no longer exposed to air flow that would reignite it.
Solution Approach 2:
The combustion device is segmented into distinct functional components: a flow guiding mechanism for flame generation, a storage tank for wick isolation, and a fuel tank. This segmentation allows independent control of flame extinguishment and wick protection, resolving the contradiction between ease of operation and extinguishment effectiveness.
2Reliability
If the user removes the shield or moves the candle wick with a long rod to extinguish the flame, then air contact with the wick is prevented, but the operation becomes difficult and scalding risk increases
Solution Approach 1:
The candle wick is preliminarily positioned in a storage tank that isolates it from the flow guiding mechanism before combustion occurs. This preliminary isolation eliminates the need for difficult post-combustion operations to prevent air contact, making flame extinguishment simple and safe.
Solution Approach 2:
The storage tank acts as an intermediary structure that physically separates the candle wick from the air flow path. This intermediary allows the wick to be protected from air contact during flame extinguishment without requiring user interaction with hot components, eliminating scalding risk.
3Object-generated harmful factors
If the flame is extinguished by blocking the opening, then the flame is extinguished, but the candle wick tip remains at high temperature and continues to convey fuel causing carbonization, smoke and odor
Solution Approach 1:
The patent extracts the candle wick from the combustion zone and places it in a storage tank isolated from air flow. This extraction prevents the wick tip from remaining at high temperature after flame extinction, stopping the continuous fuel conveyance that causes carbonization, smoke, and odor.
Solution Approach 2:
The storage tank creates an inert environment for the candle wick by isolating it from air flow. This inert atmosphere prevents oxygen contact with the hot wick tip, stopping the thermal decomposition processes that generate carbonization, smoke, and unpleasant odors.
4Reliability
If a containment lid is placed on the candle wick to prevent air contact, then air contact is prevented, but the operation is difficult when the flame is large and scalding risk exists
Solution Approach 1:
The candle wick is preliminarily positioned in a storage tank that provides inherent protection from air contact. This preliminary arrangement eliminates the need for users to handle hot components or place containment lids on scalding surfaces, removing the scalding hazard while maintaining extinguishment effectiveness.
Solution Approach 2:
The storage tank serves as an intermediary structure that provides physical protection and isolation for the candle wick. This intermediary allows the wick to be contained and protected from air contact without requiring user interaction with hot surfaces, eliminating scalding risk while ensuring reliable flame extinguishment.

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 solution allows for easy flame extinguishment without scalding risks, minimizing smoke and odor by controlling fuel flow and using a smaller capacity tank to limit flame duration, enhancing user safety and reducing carbonization.
