Solution Approach 1:

The induction heating system replaces the high-power ceramic heater with a more energy-efficient electromagnetic induction system. The coil member generates a magnetic field that induces eddy currents in the metal tube, creating heat more efficiently. This reduces the overall power consumption required to maintain the heating temperature, thereby extending battery usage time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes the electromagnetic field, which can be considered a form of energy loss in traditional systems, and converts it into useful heating through eddy current induction. The magnetic field generated by the coil member induces currents in the metal tube, transforming electromagnetic energy directly into thermal energy with higher efficiency, thus reducing the burden on the battery.
