Solution Overview
Problem
Conventional induction heating cooktops face issues with temperature sensing due to separate installation of temperature sensors, which increases manufacturing cost and time, occupies additional space, and interferes with working coil patterns, limiting space utilization and burner count.
Innovation Solution
Integrally forming a temperature sensor with a coil circuit board module, positioning it within the sensing coil pattern area, and isolating it from the working coil pattern to prevent interference and heat conduction, thereby optimizing space utilization and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temperature sensor is separately installed on the cooktop, then temperature sensing function is achieved, but manufacturing cost and manufacturing time increase
Solution Approach 1:
The temperature sensor is integrated directly into the coil circuit board module, merging the temperature sensing function with the existing coil assembly structure. This eliminates the need for separate installation of temperature sensors and reduces the number of components, thereby lowering manufacturing cost and simplifying the manufacturing process while maintaining reliable temperature sensing capability
2Reliability
If a temperature sensor is separately installed on the cooktop, then temperature sensing function is achieved, but space utilization deteriorates
Solution Approach 1:
The temperature sensor is merged with the coil circuit board module, utilizing the same space that would otherwise be occupied by separate components. This integration approach maximizes space utilization by eliminating the need for additional dedicated space for temperature sensor installation while ensuring reliable temperature sensing functionality
3Reliability
If a temperature sensor is separately installed on the cooktop, then temperature sensing function is achieved, but additional wiring and fixing structures are required
Solution Approach 1:
The temperature sensor is combined with the coil circuit board module into a single integrated unit. This merger eliminates the need for separate wiring connections and fixing structures that would be required for independently installed temperature sensors, thereby reducing device complexity while maintaining effective temperature sensing capability
Solution Approach 2:
The coil circuit board module is designed to serve multiple functions: generating the magnetic field for induction heating and sensing temperature. By making the system multi-functional, the patent eliminates the need for dedicated temperature sensing components and their associated wiring and mounting structures, simplifying the overall device architecture
4Power
If the vertical size of individual burner is increased to accommodate multi-layer working coil, then output of individual burner increases, but the percentage of entire vertical size occupied by burner increases
Solution Approach 1:
The patent transitions from a vertical stacking approach to a planar integration approach by forming working coil patterns directly on a printed circuit board. This dimensional change allows the burner to maintain high output power through multi-layer coil patterns while keeping the vertical profile thin, as the complexity is resolved in the horizontal plane rather than increasing vertical height

Function Achieved in This Case
The integrated temperature sensor design enhances space utilization, improves temperature detection accuracy, and minimizes manufacturing time and costs by eliminating separate installation structures and wiring, while allowing for more burners on the cooktop.
Implementation Method 1
when high-frequency power is applied to a working coil, a magnetic field may be generated around the working coil. An eddy current is generated in the cooking container made of a magnetic material under the generated magnetic field, and the food cooking may be performed by the cooking container which acts as a resistor against the eddy current and generates heat.
