Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent uses composite materials by combining inorganic silicon dioxide core with organic silane precursor coating. The core provides far-infrared radiation performance while the organic coating layer reduces biotoxicity and allergenicity, creating a composite structure that integrates benefits of both material types.

Inventive Principle:
