Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire columns with glass cylinders are prone to tipping over, posing a safety risk due to high construction complexity and effort, and require complex assembly, especially when handling hot components.
Innovation Solution
A fire column design featuring a tight-fitting outer shell over guide elements with a 20% axial overlap, a robust base, and adjustable air intake, eliminating the need for separate air channels and reducing manufacturing complexity by integrating guide elements with the base and fuel chamber as a single casting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the glass cylinder rests on the base, then assembly is simple, but the fire column is unstable and can be easily knocked over
Solution Approach 1:
The base is divided into two functional parts: a lower support portion and an upper guide element assembly. The guide elements are separate components that can be attached to the base, creating a segmented structure that provides both ease of assembly and enhanced stability through the distributed weight and geometry of the separate elements.
Solution Approach 2:
The guide elements extend vertically from the base, adding height and creating a three-dimensional structure. This vertical dimension increases the moment of inertia and stabilizes the fire column by distributing the center of gravity, preventing easy toppling while maintaining simple assembly.
2Temperature
If multiple components are used for cooling, then cooling effectiveness improves, but construction effort and device complexity increase
Solution Approach 1:
The guide elements serve dual functions: they direct airflow to create the vortex flame pattern and simultaneously act as cooling channels for the outer glass cylinder. By merging these two functions into a single structural component, the design achieves effective cooling without adding separate cooling mechanisms, thereby reducing construction effort and device complexity.
Solution Approach 2:
The guide elements are designed as multi-functional components that perform both flow guidance for flame formation and thermal cooling of the cylinder. This universal design eliminates the need for dedicated cooling systems, reducing the number of parts and assembly steps while maintaining cooling effectiveness.
3Adaptability or versatility
If guide elements are individually attached with metal rings, then assembly is flexible, but manufacturing complexity and construction effort increase
Solution Approach 1:
The guide elements are integrated directly into the base structure or attached as a unified assembly rather than being individually mounted with separate metal rings. This merging of components simplifies the manufacturing process by reducing the number of fastening operations and eliminates the need for additional metal ring parts, while still allowing for flexible assembly configurations.
4Stability of the object's composition
If the outer shell is tightly fitted over guide elements, then stability improves, but air channel isolation increases device complexity
Solution Approach 1:
The outer shell is designed with a tight fit over the guide elements, merging the structural support and air channel definition functions into a single component interface. This eliminates the need for separate air channel boundaries or additional sealing elements, as the tight fit itself provides both mechanical stability and airflow channel isolation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures stability and safety by preventing accidental tipping, reduces manufacturing costs, and allows safe handling without gloves, while achieving intense air vortexes and efficient cooling of the glass cylinder, eliminating the need for additional cooling mechanisms.
Implementation Method 1
The incoming air is deflected by the guide elements into a vortex or swirling flow
Implementation Method 2
The increased flow rate (with six guide elements) cools the outer casing (especially the inner wall of the glass cylinder)
Implementation Method 3
The tight fit thus largely prevents the passage of supply air from one air channel to an adjacent one, while still allowing for slight, vertical lifting of the outer shell

AI summary
To create a safe and simply constructed fire column, the flame of which is fed by a fuel container, particularly for bioethanol, and surrounded by an outer shell (4), wherein supply air flows largely axially into the lower region of the outer shell via several guide elements (3) and is preferably set into a helical rotation to form a vortex flame, it is proposed that the outer shell (4) be placed over the guide elements (3). Preferably, the outer shell (4) is centered in an upright position by the outer edges (3a) of the guide elements (3).
