Vessel attachment system for a portable stove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vessel attachment systems for portable stoves are prone to wear, leading to a risk of unintended separation between the vessel and the stove, which can result in accidents and increased fire risk due to loose vessel placement.
Innovation Solution
A vessel attachment system featuring a polygonal opening in the vessel's bottom area and a corresponding polygonal supporting means that provides a secure positive lock through relative rotational movement, with a mechanical stop to limit rotation and prevent unintended detachment, and a twin bottom structure for convenient handling and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radial pin and L-shaped slot attaching means are used, then the vessel can be fixed to the vessel support, but the system is strongly subject to wear leading to malfunction over time
Solution Approach 1:
The patent replaces the conventional radial pin and L-shaped slot (sharp edges) with a polygonal attaching means that has rounded corners. This curvature modification reduces stress concentration and wear at the contact points, thereby extending the service life of the attaching means while maintaining reliable vessel fixation to the vessel support over time
2Device complexity
If the vessel is loosely placed on the vessel support, then the attachment system is simple, but the vessel may fall down causing injury or fire
Solution Approach 1:
The patent employs an asymmetric polygonal attaching means where the polygonal opening in the vessel bottom and the corresponding polygonal protrusion on the vessel support have complementary shapes that only fit together in a specific orientation. This asymmetric design provides inherent directional guidance during attachment, ensuring proper alignment and secure fixation while maintaining relative simplicity of the overall system structure

AI summary
The present invention is directed to a vessel attachment system (1) for a portable stove comprising a vessel (2) and a vessel support (3), wherein the vessel (2) comprises a first attaching means and the vessel support (3) comprises a second attaching means. The first attaching means and the second attaching means are configured to provide for a positive locking between the vessel (2) and the vessel support (3). The invention is characterized in that the first attaching means is a polygonal opening (4) in a bottom area of the vessel (2) and the second attaching means is a polygonal supporting means (5), wherein the polygonal supporting means (5) is insertable into the polygonal opening (4). Subsequent relative rotational movement between the vessel (2) and the vessel support (3) after insertion of the polygonal supporting means (5) in to the polygonal opening (4) provides for the positive locking between the vessel (2) and the vessel support (3).
