Cooking device and control method therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking devices often malfunction due to unintended user operations, posing safety risks as they can operate differently from the user's intention, particularly when touched by pets or accidental contact.
Innovation Solution
A cooking device with a touch region and a malfunction prevention region, where the processor determines whether to perform a function command based on input from the touch region alone or in combination with the malfunction prevention region, preventing unintended operations by distinguishing between intended and unintended user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch key with simple contact operation is used, then ease of operation is improved, but reliability deteriorates due to unintended operations
Solution Approach 1:
The touch sensor is divided into multiple independent touch regions (first touch region, second touch region, third touch region) arranged in a matrix pattern. Each region can be touched independently, allowing the system to distinguish between intentional single-region touches and unintentional multi-region touches (such as pet licking), thereby preventing malfunction while maintaining ease of operation.
2Ease of operation
If touch region area is increased for easier input, then ease of operation is improved, but reliability deteriorates due to increased accidental contact
Solution Approach 1:
The touch sensor is divided into multiple independent touch regions (first touch region, second touch region, third touch region) arranged in a matrix pattern. Each region can be touched independently, allowing the system to distinguish between intentional single-region touches and unintentional multi-region touches (such as pet licking), thereby preventing malfunction while maintaining ease of operation.
Solution Approach 2:
Different touch regions are assigned different functions (power on/off, temperature selection, timer setting). The system evaluates touch patterns locally across different regions to determine user intent, allowing larger overall touch area while maintaining reliability through local pattern recognition.

AI summary
A cooking device according to the present disclosure comprises: a heating device for heating a cooking material; an input device having a touch region receiving an input of a function command related to control of the heating device and a malfunction prevention region disposed around the touch region; and a processor for, when a user operation is input through the touch region, determining whether to perform the function command, and when the performing of the function command is determined, controlling the heating device so as to allow an operation corresponding to the function command to be performed, wherein the processor determines to perform a function command corresponding to the touch region when a user operation is input only to the touch region, and determines not to perform the function command corresponding to the touch region when user operations for the touch region and the malfunction prevention region are input together.
