The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A thermo-adaptive iron system is disclosed that integrates a TCS34725 RGB color sensor, an infrared surface temperature sensor, and an FSR 402 force sensor with an ESP32 microcontroller to provide fully automated fabric type detection and temperature regulation without manual user input. The RGB color sensor reads the spectral reflectance characteristics of a fabric surface and transmits the data to the microcontroller, which classifies the fabric type from a pre-calibrated internal database encompassing cotton, silk, polyester, linen, wool, and synthetic blended materials, and retrieves the corresponding target ironing temperature. The infrared sensor provides continuous real-time soleplate temperature feedback that the microcontroller employs within a proportional-integral-derivative closed-loop control algorithm to precisely modulate a pulse-width modulation signal driving a solid-state relay connected to the heating element, thereby maintaining the soleplate temperature at the optimal value for the identified fabric with high accuracy and minimal thermal deviation. The force sensor continuously monitors user-applied contact pressure to determine active and inactive operational states, enabling the system to automatically transition between full-power ironing mode, reduced-power energy-saving standby mode, and complete auto-shutoff mode based on configurable inactivity time thresholds. An OLED display module provides the user with real-time visual feedback of fabric type identification, current and target temperatures, active operational mode, and all safety alerts generated by the overheat protection and auto-shutoff safety subsystems. The firmware architecture utilizes a FreeRTOS real-time operating system framework for concurrent execution of all control and monitoring tasks. In an optional embodiment, a servo motor controls an adjustable steam vent assembly whose aperture is regulated according to detected fabric type."
