Solution Overview
Problem
Existing wireless induction heating systems face issues with aligning a wireless induction heating cooker relative to an induction heating apparatus, leading to potential misalignment and compromised cooking performance, as users manually attempt to position the cooker, which can result in incomplete cooking or overheating due to misalignment.

A wireless induction heating system equipped with multiple temperature sensors on the internal pot and a control module that determines alignment state, providing a guide signal to users through audio or visual cues, indicating the necessary adjustments in direction and distance to achieve proper alignment with the induction heating apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually align the wireless induction heating cooker on the induction heating apparatus, then the device can be positioned for operation, but misalignment occurs leading to compromised cooking performance
Solution Approach 1:
The patent employs temperature sensors distributed around the internal pot to detect temperature differences caused by misalignment with the working coil. The control module processes these temperature signals and provides visual feedback through indicators (such as arrows or light patterns) to guide users in adjusting the cooker's position. This closed-loop feedback system enables users to achieve proper alignment without requiring manual precision, thereby resolving the contradiction between ease of operation and cooking performance reliability.
2Ease of operation
If the wireless induction heating cooker is misaligned on the induction heating apparatus, then the device can still be operated, but incomplete cooking or overheating occurs
Solution Approach 1:
The system uses temperature sensors to continuously monitor the alignment state by detecting temperature distribution patterns around the internal pot. When misalignment is detected, the control module generates visual guidance signals that indicate the direction and magnitude of adjustment needed. This feedback mechanism maintains operation capability while automatically compensating for alignment precision issues, allowing the system to operate effectively regardless of initial positioning accuracy.
3Measurement precision
If multiple temperature sensors are added to detect alignment state, then alignment accuracy improves, but device complexity increases
Solution Approach 1:
The patent strategically places a small number of temperature sensors (typically 3-4) at specific positions around the internal pot to detect temperature differences caused by misalignment. The control module uses simple comparison logic to determine alignment status based on these temperature signals and provides visual feedback through indicators. This approach achieves sufficient alignment detection precision without requiring complex sensor arrays or sophisticated processing algorithms, thereby balancing measurement precision with device complexity.
