Induction Cooktop Visual Feedback for Cooking Vessel Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction cooktops lack clear visual feedback for the positioning and size of cooking vessels, leading to user uncertainty when adjusting heat levels, as existing systems only provide Boolean indications of vessel presence without size or position information, resulting in potential misplacement and inefficient heating.
Innovation Solution
An induction cooktop with a detector and controller that provides size and position information of cooking vessels, using light sources or graphical interfaces to guide users into optimal positions for improved heating efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If Boolean detection is used to indicate vessel presence, then the system is simple to implement, but the user interface lacks clarity about vessel size and position
Solution Approach 1:
The system provides visual feedback through light sources that display the detected size and position of the cooking vessel on the cooktop surface. This feedback loop allows users to see exactly where the vessel is positioned and its detected dimensions, resolving the information loss while maintaining relatively simple detection hardware.
Solution Approach 2:
The patent introduces light sources as an intermediary between the detection system and the user. These light sources visually represent the vessel's position and size information, translating raw detection data into comprehensible visual feedback without complicating the core detection mechanism.
2Productivity
If power delivery coils are adapted to match cooking article location, then heating efficiency improves, but the system lacks feedback to indicate proper positioning
Solution Approach 1:
The light sources provide real-time visual feedback showing the detected position and size of the cooking vessel. This allows users to see whether the vessel is properly positioned on the cooktop and makes adjustments accordingly, increasing user confidence while maintaining efficient heating through coil adaptation.
Solution Approach 2:
The system uses different light colors to indicate various states: green light indicates proper positioning and optimal heating conditions, while yellow or red lights indicate positioning issues. This visual coding system makes it easy for users to understand the heating status and adjust vessel placement accordingly.
3Adaptability or versatility
If zoneless cooktops use general match for cooking article location, then adaptability improves, but clarity about cooking zone position is lost
Solution Approach 1:
The light sources act as visual intermediaries that display the detected cooking zone position and vessel location on the cooktop surface. This maintains the flexibility of zoneless operation while providing clear visual information about where heating is occurring and whether the vessel is properly positioned.
Solution Approach 2:
The system creates a visual copy or representation of the cooking zone and vessel position using light sources on the cooktop surface. This graphical representation allows users to see the abstract concept of a zoneless cooking area in concrete visual terms, maintaining adaptability while improving clarity.

AI summary
An induction cooktop (10) includes a cooktop surface (12), a plurality of power delivery coils (14) in an array (62) beneath the cooktop surface (12), a cooking article detector (16), a light source (26) directed toward the cooktop surface (12), and a controller (18). The controller (18) receives a signal (20) from the cooking article detector (16) including size and position information for at least one detected cooking article on the cooktop surface (12) and determines that a detected position (22) of the detected cooking article does not correlate with a preferred position (24) of the cooking article with respect to at least one of the plurality of power delivery coils (14). The controller (18) then presents an indication (28), preferably via the light source (26), of the preferred position (24) of the detected cooking article on at least one of the detected cooking article and the cooktop surface (12).
