Solution Overview
Problem
Existing cooktops with multiple heating units lack efficient and user-friendly methods for optimizing the use of these units, particularly when dealing with cooking vessels of varying sizes and shapes, often leading to energy wastage and uneven heating.
Innovation Solution
The method involves providing persistent indicators on the cooktop surface to guide users in positioning cooking vessels to cover the maximum number of heating zones, optimizing energy use by ensuring the vessel covers the appropriate heating elements, and using sensors to provide real-time feedback on optimal placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooking vessels are placed as close to the back edge of the cooktop as possible, then safety is improved (vessels are less likely to be knocked off), but energy efficiency deteriorates (heating units are not optimally utilized)
Solution Approach 1:
Visual indicators (marks or lights) are introduced as intermediaries between the heating zones and the cooking vessel. These indicators guide users to position vessels optimally by showing which heating zones should be covered, thereby resolving the conflict between safety positioning and energy efficiency without requiring complex automation.
2Power
If multiple heating units are used with a single cooking vessel, then heating capability is improved, but energy wastage occurs if the vessel does not cover the heating units efficiently
Solution Approach 1:
The system provides visual feedback through indicators that show users whether their vessel placement is optimal for energy efficiency. The indicators communicate information about which heating zones are being utilized effectively, enabling users to adjust vessel position to maximize energy usage while maintaining high heating capability.
3Adaptability or versatility
If cooking vessels of varying sizes and shapes are used, then versatility is improved, but optimization difficulty increases (users cannot efficiently position vessels to cover heating zones)
Solution Approach 1:
Visual indicators serve as a universal intermediary that adapts to different vessel sizes and shapes. By showing users which heating zones should be covered regardless of vessel dimensions, the indicators make it easy for users to optimize positioning with any vessel type, thereby maintaining versatility while improving ease of operation.
4Device complexity
If known cooktops provide no instructions for optimizing multiple heating units, then device complexity is reduced, but user performance optimization deteriorates
Solution Approach 1:
Visual indicators provide optimization guidance without adding mechanical or electronic complexity to the heating system itself. The indicators act as a simple intermediary layer that communicates optimal positioning information to users, thereby improving cooking efficiency while maintaining device simplicity.

AI summary
A method of optimizing performance of a cooktop with a plurality of adjacent heating zones includes indicating a point for each heating zone; placing a cooking vessel on the cooktop, the cooking vessel being sufficiently large to cover at least two of the points simultaneously; and adjusting the cooking vessel so that the cooking vessel covers the maximum number of the points possible for the size of the cooking vessel. A cooktop includes at least three induction heating elements; and a persistent indicator for each heating element. The cooktop is adapted to instruct a user to cover a maximum possible number of the at least three persistent indicators with a cooking vessel to optimize use of the cooktop.
