Gesture-Controlled Electric Range for Rapid Heat Power Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric ranges, particularly induction heating types, lack the ability to rapidly adjust heat power and require cumbersome touch operations, making it difficult to respond quickly to emergency situations during cooking, such as overheating, and do not allow for convenient activation of additional functions without separate user manipulation.
Innovation Solution
An electric range that determines the movement of a heated item and provides corresponding functions, including heat power adjustments and additional features, by using a control unit to manage heating units and an input interface, allowing for gesture-based control of heat power and function activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If touch operation is used to control heat power on electric range, then heat power can be adjusted, but the adjustment speed is slow compared to knob operation
Solution Approach 1:
The patent replaces the mechanical knob operation with a touch-sensitive interface that detects gestures (sliding, tapping, long-pressing) to control heat power. This substitution enables faster adjustment response while maintaining ease of operation through intuitive gesture-based control, directly resolving the contradiction between adjustment speed and operational convenience.
2Adaptability or versatility
If separate operations are required to activate additional functions, then functions can be provided, but user manipulation time increases
Solution Approach 1:
The patent implements a multi-functional touch interface where different gestures (slide direction, press duration, tap patterns) trigger different functions including heat power adjustment, timer activation, and child lock. This universal interface consolidates multiple separate operations into a single gesture-based system, providing diverse functions while minimizing user manipulation time.
Solution Approach 2:
The system automatically determines which function to activate based on the detected gesture pattern without requiring users to navigate through menus or press multiple buttons. The touch interface self-adapts to user intent through gesture recognition, enabling rapid activation of additional functions without separate manipulation steps.
3Reliability
If conventional touch operation is used for emergency situations, then heat power can be adjusted, but rapid response is difficult due to repeated touch operations required
Solution Approach 1:
The patent implements a long-press gesture that allows users to pre-select and rapidly adjust heat power levels in emergency situations. By pressing and holding the touch interface, users can quickly reduce heat power without needing to perform multiple separate touch operations, enabling immediate response to emergencies like boiling over while maintaining operational reliability.

AI summary
Disclosed is an electric range which provides specific functions according to the gestures of a user. When an object to be heated that is currently being heated is moved to a different spot, the electric range determines in what way the object to be heated has been moved, and provides a specific function corresponding to the determined way of movement.
