Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable induction stoves face challenges in stability and overheating issues due to the proximity of electronics to the induction elements, limiting their use, especially in mobile setups where spacing is not feasible, and existing solutions like EP 09 711 562 result in large, cumbersome designs.
Innovation Solution
A demountable assembly using non-magnetic spacers and adjustable feet with a coupling mechanism to create space between the induction element and the pan, allowing for easy assembly and disassembly, and an optional second electromagnetic element for uniform heating, along with a heat-insulating lining and a probe for content detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the induction element is placed close to the pan for efficient heating, then heating efficiency is improved, but the electronics overheat and shut down
Solution Approach 1:
The patent introduces a vertical spacing dimension between the induction element and pan by using adjustable feet and support structure. This creates a three-dimensional arrangement where the induction element remains horizontally positioned for efficient heating while being vertically separated from the pan bottom, allowing heat to be generated in the pan without directly transferring to the electronics below.
Solution Approach 2:
The support structure with adjustable feet acts as an intermediary element between the induction element and the pan. This intermediary component enables the pan to be positioned at an optimal distance from the induction element, ensuring efficient electromagnetic coupling for heating while preventing direct thermal contact that would cause electronics overheating.
2Reliability
If the induction element is spaced far from the pan to prevent overheating, then electronics are protected, but heating efficiency decreases
Solution Approach 1:
The patent employs adjustable feet with movable support surfaces that allow dynamic adjustment of the pan position relative to the induction element. This dynamic positioning system enables users to optimize the distance for each heating task, achieving the right balance between maintaining sufficient electromagnetic coupling for efficient heating and preventing direct thermal contact that would overheat the electronics.
3Ease of operation
If a fixed support structure is used for the pan, then assembly is simple, but stability against overturning is reduced
Solution Approach 1:
The adjustable feet incorporate a dynamic coupling mechanism with guide rails and locking positions that provide both ease of assembly and operational stability. The feet can be quickly positioned and locked into place, creating a stable support structure that resists overturning while maintaining simple assembly through the guide-rail-based coupling system.
Solution Approach 2:
The support structure is divided into modular components - the adjustable feet are separate from the main body and can be independently positioned and secured. This segmentation allows each foot to be optimized for both easy attachment/detachment and providing stable support, with the overall structure gaining stability from the distributed footprint of multiple adjustable feet.
4Quantity of substance
If a large induction surface is used to heat large pans, then heating capacity is improved, but the device becomes difficult to transport
Solution Approach 1:
The induction heating system is divided into separate modular components - the induction element assembly can be detached from the support structure with adjustable feet. This segmentation allows the induction element to be used with different pan sizes by adjusting the support structure, maintaining heating capacity for large pans while enabling easy transport by separating the components.

Function Achieved in This Case
Enables rapid and reliable assembly, prevents overheating of electronics, and ensures uniform and fast heating of contents while maintaining stability, enhancing the usability of portable induction heating systems.
Implementation Method 1
This heating can take place via an induction element. As is well known, induction heating of conductive or ferromagnetic metals is one of the radio frequency heating modes and relies on the generation of heat due to eddy currents generated in the conducting materials when they are immersed in a radio frequency magnetic field.
Implementation Method 2
A demountable assembly for induction plates which spaces any element/element to be heated, for example a pan or other container, from the induction element to avoid contact heat transfer.
