Induction Heating Coil Support Framework Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induction heating cooking devices face challenges in maintaining a constant distance between the heating coil and the top plate due to deformation of the framework under load, leading to stress on the top plate and complexity in configuration, which affects performance and ease of assembly.
Innovation Solution
The induction heating cooking device is designed with a framework that uses first and second horizontal parts and vertical parts to support the heating coil unit, eliminating the need for springs and reducing the number of components, thereby maintaining a constant distance and simplifying the configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If springs are used to press the coil base upward to maintain distance, then the distance between heating coil and top plate can be kept constant, but the configuration becomes complex and the top plate is subjected to continuous stress
Solution Approach 1:
The patent removes the springs and coil base from the system, extracting the problematic components that caused complexity and stress. The heating coil is directly mounted to the framework without intermediate pressing mechanisms, eliminating the need for springs while maintaining the required distance through direct structural support.
Solution Approach 2:
The framework is divided into specific supporting parts that directly hold the heating coil at the correct position. By segmenting the framework into functional supporting elements, the patent achieves precise positioning without requiring additional springs or adjustment mechanisms.
2Ease of manufacture
If multiple components are stacked on the bottom surface of the framework, then the heating coil can be positioned, but the bottom surface deflects under load affecting distance consistency
Solution Approach 1:
Instead of stacking components vertically on the bottom surface (one dimension), the patent distributes the support across multiple horizontal parts of the framework (spreading across dimensions). The heating coil is supported by horizontal parts extending from different sides of the framework, transforming a vertical stacking problem into a distributed spatial support solution.
3Manufacturing precision
If springs are always in compressed state to maintain distance, then constant distance is achieved, but stress is continuously applied to the top plate
Solution Approach 1:
The patent extracts the springs that were causing continuous stress on the top plate. By removing the pressing mechanism entirely and using direct structural support from the framework, the harmful continuous compressive stress is eliminated while the heating coil maintains its proper distance from the top plate through rigid framework support.

AI summary
In order to provide an induction heating cooking device in which a supporting configuration of a heating coil unit is simple and can be easily assembled, and which can accurately and constantly maintain a distance between a top plate and heating coils, opposite side surfaces of a framework laid out below the top plate are configured to have first vertical parts, first horizontal parts, and second vertical parts. A heating coil supporting member that supports the heating coils is disposed to be bridged between the first horizontal parts of the opposite side surfaces of the framework, and the heating coil unit having the heating coil is configured to be securely supported by the first horizontal parts.
