Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction ranges face issues with durability and thermal efficiency due to improper installation, where the distance between the coil and the container can vary, leading to excessive operation and component damage.
Innovation Solution
An under-induction range system that uses a noncontact type Hall sensor and a multi-support unit with a magnetic member to control power supply to the coil, automatically blocking power when the system operates outside a proper range and optimizing thermal efficiency by determining the thickness of the top plate and the height between the coil and the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the induction range is installed under a dining table with varying top plate thickness, then the installation flexibility is improved, but the distance between the coil and the dedicated container becomes out of proper heating range
Solution Approach 1:
The system performs preliminary detection of the top plate thickness using a sensor before initiating heating operation. Based on the detected thickness, the control unit pre-adjusts the coil position or heating parameters to ensure the container is within the proper heating range, preventing heating inefficiency before it occurs.
Solution Approach 2:
The system dynamically adjusts the coil position or heating power based on real-time feedback from the sensor that measures the distance between the coil and the container. This dynamic adjustment ensures consistent heating performance despite variations in top plate thickness across different installation locations.
2Ease of operation
If the distance between the coil and the dedicated container is not properly controlled, then the ease of installation is improved, but the thermal efficiency and durability of the induction range deteriorate
Solution Approach 1:
The system employs a sensor to continuously detect the distance between the coil and the dedicated container during operation. The control unit receives this feedback and automatically adjusts the coil position or heating parameters to maintain optimal distance, ensuring high thermal efficiency without complicating the installation process.
Solution Approach 2:
The induction range system automatically monitors and adjusts its own coil position or power output based on sensor feedback regarding the container distance. This self-regulating mechanism maintains optimal thermal efficiency without requiring manual intervention or complex installation procedures.
3Adaptability or versatility
If the induction range operates outside proper operating range due to distance variations, then the adaptability to different installation positions is improved, but the durability and component reliability worsen
Solution Approach 1:
Before operation, the system detects the installation position and top plate thickness using integrated sensors. Based on this preliminary information, the control unit pre-configures the coil position and heating parameters to ensure operation remains within the proper range, preventing component stress and durability issues before they occur.
Solution Approach 2:
The system dynamically monitors the distance between the coil and container during operation and automatically adjusts parameters to maintain optimal operating conditions. This dynamic control ensures that even with varied installation positions, the components operate within safe and efficient parameters, preserving durability.
4Device complexity
If no detection mechanism is used to monitor the distance between coil and container, then the device complexity is reduced, but the ability to control operation within proper range is worsened
Solution Approach 1:
The system replaces complex mechanical measurement and adjustment mechanisms with a non-contact sensor and electronic control system. The sensor optically or electromagnetically detects the distance between the coil and container, and the control unit electronically adjusts parameters, achieving precise operational control with simpler and more reliable components.
