Solution Overview
Problem
Conventional tabletop induction heating devices face issues with heat generation and electrical short-circuits due to closely packed components, and they can be unstable on tables, posing a risk of accidents during cooking.
Innovation Solution
The design features a case divided into two sections with a plate-fitting insertion space, allowing the power supply unit and working coil to be spaced apart, reducing thickness and preventing heat and electrical issues, while a pressure sensor and slip prevention member enhance stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the induction heating device is made thin to improve appearance, then the aesthetic quality is improved, but the components become too close together causing heat generation and electrical short-circuits
Solution Approach 1:
The case is divided into a first case and a second case that are separable from each other. The power supply unit is accommodated in one case while the working coil is accommodated in the other case, physically separating components that generate heat and electrical fields. This segmentation allows the device to maintain a thin profile while preventing harmful interactions between components through the table plate barrier.
2Shape
If the induction heating device is made thin to improve appearance, then the aesthetic quality is improved, but heat dissipation becomes insufficient
Solution Approach 1:
The power supply unit, which generates significant heat during operation, is extracted from the main device body and accommodated in a separate case. This extraction removes the primary heat source from the thin device body, enabling effective heat dissipation while maintaining the aesthetic thin profile. The separated power supply unit can be positioned away from the working coil area, preventing heat accumulation.
3Device complexity
If the device is designed as a single integrated unit, then the structure is simple, but the device moves undesirably on the table causing accidents
Solution Approach 1:
The device is segmented into separable cases that can be independently positioned on the table. The first case with the working coil remains on the table surface for heating operations, while the second case with the power supply unit can be positioned stably or secured separately. This segmentation allows the heating portion to remain lightweight and movable for cooking operations while the power supply portion can be stabilized independently, preventing the entire device from sliding.
4Length of stationary object
If the components are placed close together to reduce thickness, then the device becomes thinner, but heat generation and electrical short-circuits occur
Solution Approach 1:
The table plate serves as an intermediary barrier between the power supply unit and the working coil. When the device is placed on the table, the table plate physically separates the power supply unit (in one case) from the working coil (in the other case), preventing direct thermal and electrical interaction. This intermediary allows the cases to be positioned close together for a thin profile while the table plate maintains safe separation between harmful components.
