Solution Overview
Problem
Conventional tabletop induction heating devices face issues with undesirable 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 divided case structure with the power supply unit and working coil spaced apart, allowing a table plate to fit between them, reducing thickness and enhancing stability, while also incorporating a pressure sensor and slip prevention member to secure the device and prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the induction heating device is manufactured with thin thickness 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 separated by a predetermined distance, with the power supply unit housed in one case and the working coil in the other. This segmentation physically isolates the components to prevent heat generation and electrical short-circuits while maintaining a thin overall profile.
2Shape
If the induction heating device is made with thin thickness, then the appearance is improved, but heat dissipation becomes insufficient
Solution Approach 1:
By separating the power supply unit and working coil into different cases with a gap between them, hot air generated by the components can flow through the space between the cases, significantly improving heat dissipation efficiency while maintaining a thin device profile.
3Ease of operation
If the induction heating device is placed on the table without proper mounting structure, then the ease of operation is improved, but the device becomes unstable and may move causing accidents
Solution Approach 1:
A table plate is introduced as an intermediary element that fits into the space between the first and second cases. The table plate provides stable support for the device on the table surface, preventing movement and accidents while maintaining ease of placement and removal.
4Volume of moving object
If the power supply unit and working coil are placed close together to reduce device size, then the volume is reduced, but undesirable heat generation and electrical short-circuits occur
Solution Approach 1:
The device is segmented into two separate cases housing the power supply unit and working coil respectively, with a predetermined distance between them. This segmentation prevents harmful heat generation and electrical short-circuits by ensuring adequate spacing between components while maintaining a compact overall device volume.
