Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional candles pose safety risks due to inefficient burning, uneven scent throw, and potential for tunneling, which negatively impact the consumer experience and safety profile.
Innovation Solution
A thermally-protective material and candle wrap or label made from a multi-layered vinyl material with metal flecks and UV/abrasion-resistant properties, applied to encircle or surround the candle, reducing exterior and molten wax temperatures, and enhancing burn time and fragrance consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If glass containers are used for candles, then the container is popular and aesthetically pleasing, but the container gets hot to the touch and may shatter
Solution Approach 1:
The patent introduces a thermally-protective material as an intermediary layer between the glass container and the user. This material wraps around the container and provides thermal insulation, preventing heat transfer to the user's hand while maintaining the aesthetic appearance of the glass container. The intermediary layer resolves the contradiction by blocking the harmful thermal effect without removing the popular glass container design.
Solution Approach 2:
The thermally-protective material is applied as a flexible wrap or label that conforms to the container shape. This thin film approach provides thermal protection without adding significant bulk or compromising the container's appearance. The flexible shell encapsulates the hot surface, allowing the container to remain popular while eliminating the hot-to-touch hazard.
2Device complexity
If conventional candles are used, then the candle structure is simple, but the burning is inefficient with uneven scent throw and tunneling
Solution Approach 1:
The patent modifies the thermal parameters of the candle system by introducing a thermally-protective material with specific thermal conductivity properties. This material changes the heat distribution pattern around the container, preventing heat loss and ensuring more uniform melting of the wax. The parameter change in thermal insulation resolves the burning inefficiency while maintaining the simple candle structure.
3Duration of action of moving object
If the candle burns efficiently with uniform heat distribution, then scent throw is consistent and burn time is extended, but the exterior and molten wax temperatures are reduced
Solution Approach 1:
The patent converts the potentially harmful effect of heat retention into a beneficial outcome. By introducing the thermally-protective material, the heat that would normally escape is now retained and redistributed more uniformly throughout the wax. This converts the harmful concentration of heat (which causes high temperatures and safety issues) into a beneficial uniform heat distribution (which extends burn time and improves scent throw). The result is that burn time is extended while the exterior temperature remains safer.
