Candle Container Wick Holder Fixing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing candle container designs fail to prevent the wick holder from moving close to the container walls when the flammable material melts, leading to potential ignition, and existing solutions either increase production costs, interfere with burning, or pose ignition risks.
Innovation Solution
A fixing device is integrated at the junction of the container wall and bottom, shaped to prevent the wick holder from moving close to the wall, using a design that is simple, cost-effective, and does not interfere with burning, ensuring the wick remains at a safe distance from the container walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a deep recess is formed at the bottom of the container to limit wick holder movement, then the wick holder position is restricted, but the container loses stability and filling volume reduces
Solution Approach 1:
The invention transitions from a two-dimensional bottom recess to a three-dimensional fixing device with vertical extension. The fixing device rises from the bottom surface into the container interior, creating a multi-dimensional constraint system that limits wick holder movement in multiple directions simultaneously, thereby achieving reliable position restriction without compromising container stability or volume.
Solution Approach 2:
The fixing device acts as an intermediary element between the container bottom and the wick holder. Rather than directly modifying the bottom surface with deep recesses, the fixing device serves as a mediating structure that provides the necessary mechanical constraint while preserving the integrity and stability of the container body.
2Reliability
If sharp projections are formed at the bottom of the container to prevent wick position change, then wick holder movement is effectively prevented, but the projections themselves may ignite when close to the flame
Solution Approach 1:
The invention changes the geometric parameters of the fixing structure by replacing sharp, high projections with lower, broader elements. This parameter modification reduces the height of the fixing features, keeping them at a safer distance from the flame while maintaining their position-stabilizing function through increased surface area and distributed contact points.
Solution Approach 2:
The invention replaces sharp, angular projections with curved or rounded fixing elements. This curvature eliminates concentrated stress points and reduces the likelihood of ignition by distributing thermal exposure over a broader, smoother surface that does not concentrate heat in the same way sharp edges do.
3Reliability
If a plate with a hole is used to limit wick movement, then the wick position is controlled, but production costs increase due to additional manufacturing and assembly steps
Solution Approach 1:
The invention merges the fixing function directly into the container structure itself, eliminating the need for separate plates or additional components. The fixing devices are integrated as part of the container's bottom construction, combining the structural and positional control functions into a single unified element, thereby reducing manufacturing steps and assembly complexity.
Solution Approach 2:
The container bottom structure serves multiple functions simultaneously: it provides structural support, defines the container volume, and incorporates fixing devices for wick holder positioning. This multi-functionality eliminates the need for dedicated separate components, simplifying the overall device and reducing production costs.
4Reliability
If non-flammable materials are used for the container to prevent ignition, then safety is improved, but the costs for production increase
Solution Approach 1:
The fixing devices serve as intermediary protective elements between the flame and the container wall. By positioning these fixing structures at strategic locations, they act as mediators that maintain safe distances and prevent direct flame contact with the container material, enabling the use of more cost-effective materials that would otherwise be too flammable.
Solution Approach 2:
The fixing devices are pre-positioned during container manufacturing to establish safe geometric relationships between the wick holder and container walls before the candle is assembled. This preliminary positioning ensures that even with less fire-resistant materials, the design inherently prevents ignition by maintaining adequate clearance distances from the flame to the container surface.

AI summary
Containers which contain flammable materials, wicks and other elements are used for the production of a candle. Typically containers of non-flammable materials such as glass, aluminum (or other metal), ceramics, etc. are used for the production of a candle. In order to produce a container of the candle of the flammable materials it is necessary to ensure that when the flammable material of a candle moves into a liquid state, a candle wick will not be able to get close to a wall of the container or other elements of the container at a distance, for which there is a real threat to a wall or a container to ignite. This description provides a fixing device formed at the junction of a wall and a bottom of the container of the candle, for which a wick with its holder cannot get close to a wall of the container. Such structural solution is simple and inexpensive to implement in the production process, the solution does not interfere with the candle burning. Moreover, when using this solution, it is ensured greater strength of the container of the candle, the stability of the structure.
