Core Design Contradiction:

Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The drying device is divided into multiple drying sections (first drying section, second drying section, etc.) arranged in a specific pattern. Each section operates with normal phase voltage, and through the segmented arrangement and phase relationships, the radiation waves from individual sections interfere destructively, reducing overall radiation impact while maintaining large area heating capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent converts the harmful radiation waves into a beneficial effect by utilizing wave interference. By arranging drying sections with specific phase relationships (normal phase to adjacent sections), the radiation waves that would normally cause harm to peripheral devices are made to interfere destructively, canceling each other out and reducing overall radiation impact

Inventive Principle:
