Wick-Burning Structure with Heat Isolation Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cotton-based wicks in burning devices cause environmental pollution, poor heat isolation, and instability due to high temperature carbonization, frequent replacement needs, and susceptibility to flame jumping from wind influences.
Innovation Solution
A wick-burning and ventilation structure comprising a wick tray with heat-dissipating fuel-dropping holes, a heat isolation cover with a curved surface and support sections, and a metallic or ceramic wick with a flame-blocking sleeve, along with a wind-shielding hood to stabilize the flame and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cotton-based wick is used for burning, then the burning process can be maintained, but environmental pollution is generated and the wick requires constant replacement
Solution Approach 1:
The patent changes the material parameter of the wick from cotton-based to metallic or ceramic materials, which fundamentally alters the burning characteristics. These materials do not carbonize like cotton, eliminating PM2.5 generation while maintaining continuous burning capability through capillary fuel transport
Solution Approach 2:
The patent employs composite material structures including metallic or ceramic wicks combined with heat isolation covers and flame-blocking sleeves. This composite approach addresses both the burning continuity requirement and environmental pollution issue by using materials that burn cleanly while maintaining structural integrity
2Power
If a cotton-based wick is used, then fuel burning can be achieved, but heat isolation is poor leading to over-heating
Solution Approach 1:
The patent introduces a heat isolation cover as an intermediary component between the flame and the surrounding environment. This cover acts as a thermal barrier that isolates heat locally, preventing excessive temperature rise while allowing controlled heat dissipation through designed openings
Solution Approach 2:
The heat isolation cover provides localized thermal management by creating a controlled micro-environment around the flame. The cover isolates heat in the immediate burning area while allowing strategic heat dissipation through openings, achieving both heat isolation and controlled temperature management
3Device complexity
If no wind-shield hood is installed, then the structure remains simple, but the flame becomes unstable and jumps due to airflow influence
Solution Approach 1:
The patent employs a wind-shield hood that acts as a protective shell around the flame. This hood is designed to be relatively simple in structure but effectively blocks external airflow from directly contacting the flame, stabilizing it while maintaining overall device simplicity
Solution Approach 2:
The wind-shield hood provides preliminary protection against external airflow disturbances before they can reach and destabilize the flame. By preemptively blocking wind and air currents, the hood prevents flame jumping and instability without requiring complex active control systems
4Device complexity
If the wick is not firmly positioned, then the structure remains simple, but burning security is compromised due to falling or inclining
Solution Approach 1:
The patent divides the positioning function into separate components: a wick tray with mounting holes, support sections on the heat isolation cover, and corresponding protrusions. This segmented approach provides firm positioning through multiple contact points while keeping each individual component simple and easy to manufacture

Function Achieved in This Case
The solution provides clean burning, effective heat isolation and dissipation, prevents wick consumption, and ensures stable, non-jumping flames while shielding against winds, thus addressing environmental and safety issues.
Implementation Method 1
a heat isolation cover... to form a heat isolation space between the heat isolation cover and the wick tray
Implementation Method 2
the periphery of the heat isolation cover being also formed with at least one opening part, which defines, together with a periphery of the wick tray, a ventilation heat-dissipating space
Implementation Method 3
a flame-blocking heat-isolating sleeve being fit over and mounted to a surface of the wick between the heat isolation cover and the wick tray
Implementation Method 4
a bottom of the recess of the wick tray being provided with a plurality of heat-dissipating fuel-dropping holes

AI summary
A wick-burning and ventilation and flow-guide structure includes a wick tray, a heat isolation cover, and a wick. The heat isolation cover has support sections that are extended to form protrusion sections insertable into and mounted in mounting holes of the wick tray for secured combination and easy separation. The wick tray and the heat isolation cover provide a dual-layered heat isolation effect and also achieve an effect of heat dissipation. The wick is made of a metallic or ceramic material and has a surface over which a flame-blocking heat-isolating sleeve is fit to prevent downward spreading of flaming. A wind-shielding hood is provided on the fuel container to define therebetween a flow-guide opening for smooth ingress of air, preventing flaming from jumping.
