Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smart under range induction is installed under the table for cooking, then the magnetic field influence is increased and cooking container placement flexibility is improved, but the temperature sensing precision deteriorates because the sensing means cannot directly contact the cooking container
Solution Approach 1:
A temperature sensing pad is introduced as an intermediary component between the cooking container and the sensing system. The pad includes a temperature sensing part that directly contacts the cooking container bottom, enabling precise temperature measurement while maintaining the under-table induction setup. This mediator transfers thermal information from the container to the control system without requiring direct penetration of the table surface.
Solution Approach 2:
The patent replaces the conventional mechanical penetration method (piercing the table to install sensors) with a non-invasive sensing pad system. The temperature sensing pad uses thermal conduction through direct contact with the container bottom, substituting the need for physical table penetration and complex sensor installation while achieving accurate temperature monitoring.
2Reliability
If the temperature sensing means is installed by piercing the table, then the temperature sensing capability is improved, but the installation complexity increases
Solution Approach 1:
The temperature sensing pad serves as a portable intermediary device that achieves reliable temperature sensing without requiring permanent table modification. It includes all necessary sensing components in a self-contained unit that simply contacts the cooking container, eliminating the need for table piercing and complex installation procedures.
Solution Approach 2:
The sensing pad is designed as a self-contained unit with integrated temperature sensing, signal transmission, and power supply components. It performs temperature monitoring autonomously by directly contacting the cooking container, requiring no installation infrastructure or table modification, thus simplifying deployment while maintaining reliable sensing capability.
3Device complexity
If the temperature sensing part is arranged only at the smart under range induction under the table, then the device structure is simplified, but the temperature detection accuracy deteriorates due to difference from actual cooking container temperature
Solution Approach 1:
The temperature sensing pad acts as a direct intermediary between the cooking container and the control system, providing accurate temperature data at the point of contact. This mediator ensures that the temperature measured is precisely that of the container bottom, eliminating the temperature gradient errors that would occur with remote sensing from under the table.
Solution Approach 2:
The patent implements local temperature sensing by placing the temperature sensing part in direct contact with the cooking container bottom where heating occurs. This localized measurement approach captures the actual temperature at the critical heating zone, providing accurate data for control decisions while keeping the overall device structure relatively simple.
4Productivity
If the cooking container is placed directly on the induction range, then the heating efficiency is improved, but the contamination risk increases when food overflows
Solution Approach 1:
The system separates the heating function (under-table induction) from the container support function (body pad with cooking container supporting part). This segmentation allows the container to be supported on the body pad surface rather than directly on the induction range, maintaining heating efficiency through magnetic field penetration while preventing contamination of the induction range when food overflows.
Solution Approach 2:
The body pad serves as an intermediary surface between the cooking container and the induction range. It supports the container during heating while protecting the induction range from direct contact with food and spills, thus maintaining heating efficiency through electromagnetic coupling while eliminating contamination risks.
