Mobile Cooking Appliance Combining Radiant and Induction Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile cooking appliances lack flexibility and efficiency in heating performance, particularly when used as a mobile cooking area, as they are limited to either radiant or induction heating methods, and do not effectively combine both for versatile cooking needs.
Innovation Solution
Incorporating both a radiant heater and an induction coil into a mobile cooking appliance, with control electronics that can switch between modes, allowing for hybrid operation of the hybrid coil to provide both heat radiation and induction heating, and utilizing a 3D position sensor to determine the cooking mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only a radiant heater is used in mobile cooking appliances, then the device can heat all types of cookware, but the heating speed and energy efficiency are insufficient
Solution Approach 1:
The patent combines radiant heating elements and induction heating elements into a single mobile cooking appliance. The control unit selectively activates either the radiant heater or the induction coil based on cookware detection, merging two different heating technologies to achieve both fast heating for induction-compatible cookware and universal compatibility for all cookware types.
Solution Approach 2:
The mobile cooking appliance is designed with dual heating capabilities (radiant and induction) to serve multiple functions. The control unit automatically detects cookware type and switches between heating modes, making the device universally adaptable to different cookware materials while maintaining optimal heating performance for each type.
2Productivity
If only an induction coil is used in mobile cooking appliances, then the heating speed is fast for induction-compatible cookware, but the device cannot heat non-induction cookware
Solution Approach 1:
The patent integrates both induction heating coils and radiant heating elements in the same appliance. The control unit detects whether the cookware is induction-compatible and activates the appropriate heating source, combining the advantages of both technologies to achieve fast heating when possible and universal compatibility when needed.
Solution Approach 2:
The dual-heating system provides multi-functionality by automatically adapting to different cookware types. Induction-compatible cookware receives rapid induction heating, while non-induction cookware is heated by the radiant elements, making the appliance universally versatile without sacrificing heating speed for compatible cookware.
3Adaptability or versatility
If both radiant heater and induction coil are incorporated, then heating flexibility and speed are improved, but the device complexity increases
Solution Approach 1:
The patent merges radiant heating and induction heating systems into a unified mobile cooking appliance with a single control unit. The control electronics automatically detect cookware type and switch between heating modes, managing the complexity of dual systems through intelligent automation rather than requiring manual intervention.
Solution Approach 2:
The appliance achieves multi-functionality with automatic mode selection, where the control unit handles the complexity of coordinating both heating systems. This universal design allows the device to adapt to different cookware types and cooking scenarios without requiring the user to understand or manage the underlying system complexity.
4Device complexity
If hybrid coils are used that can operate in both radiant and induction modes, then the device structure is simplified, but the coil design complexity increases
Solution Approach 1:
The patent employs hybrid coils that can operate in both radiant and induction modes, creating a universal heating element that eliminates the need for separate radiant and induction components. This multi-functional coil design simplifies the overall device structure while the manufacturing complexity is managed through standardized production processes for dual-mode heating elements.

AI summary
A mobile cooking appliance (101, 101') has a radiant heater (21) and an induction coil (19) in its housing (11), wherein control electronics are provided with which said heating elements (19, 21) can be controlled either in an infrared radiation mode (111) or in an induction mode (110). In this case, after the conventional use of the mobile cooking appliance as a hotplate, the cooking appliance can be used for baking with an overhead arrangement, so that this function is combined with the rapid heating with eddy currents (16, 116) via bottom heat.
