Induction Cooker Interface for Single-Drag Multi-Coil Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction heating cookers face inefficiencies in controlling multiple coils due to the need for multiple screen shifts, which degrades control efficiency and increases manufacturing costs, especially when trying to control all coils simultaneously or convert the cooking process quickly.
Innovation Solution
A user interface with a display unit and sensor unit that allows for simultaneous control of all coils through a single drag touch on the main screen, enabling rapid conversion to a safe state and reducing manufacturing costs by eliminating the need for enlarged displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the user interface is provided in small size, then the manufacturing cost is decreased, but a desired control process is achieved only through a plurality of shifts of screens, and thus the efficiency of control is degraded
Solution Approach 1:
The patent merges multiple control functions (power level adjustment, cooking time setting, coil selection) into a single integrated main screen interface. All coil power levels are displayed and controllable on one screen without requiring navigation to separate pages, thus maintaining small display size while eliminating the need for multiple screen shifts.
Solution Approach 2:
The main screen is designed to perform multiple functions simultaneously: displaying power levels for all coils, adjusting individual coil power, setting cooking time, and providing cooking guidance. This multi-functional design allows the small display to provide comprehensive control without requiring additional screens or page navigation.
2Productivity
If the user interface is provided in large size, then the efficiency of control is improved, but instead, the manufacturing cost is increased
Solution Approach 1:
The interface is segmented into distinct functional zones on the main screen: power level display areas for each coil, cooking time setting section, and cooking guidance information. This segmentation allows comprehensive control functionality to be organized efficiently on a small display without requiring a large screen size.
3Device complexity
If multiple screen shifts are required for controlling coils, then the device complexity is reduced, but the time for cooking adjustment is increased
Solution Approach 1:
All necessary control elements (power level sliders, cooking time input, coil selection) are prepared and displayed in advance on the main screen. Users can immediately adjust any parameter without navigating to different screens, eliminating delays associated with screen transitions and allowing rapid cooking adjustments.

AI summary
A user interface for an induction heating cooker, a method of controlling the same and an induction heating cooker thereof are provided. The user interface, if a drag touch signal of a drag touch from one position to another position on a display unit is sensed, is configured to change power levels of all of coils in operation to a predetermined reference power level and displays the changed power level. The induction heating cooker is configured to supply the coils with a power corresponding to the reference power level, thereby controlling all of the coils with one drag touch and enabling enhanced security while in a rapid manner.
