Solution Overview

Problem

Current induction cooking systems on porcelain surfaces rely on passive thermal insulators that do not effectively prevent overheating of the ferromagnetic cooking surface, as they only provide minimal separation and lack dynamic temperature control.

Innovation Solution

The introduction of active thermal insulating separators with integrated temperature sensors and a control unit that communicate via radiofrequency signals to regulate induction power, ensuring real-time temperature adjustments and preventing overheating by providing feedback to the control unit.
