Domestic Appliance Panel Thermal Treatment for Optical Flexibility

The patent applies thermal treatment to specific sections of the raw plate rather than the entire plate, creating local variations in optical properties. This allows different areas of the panel to have different transparency or color characteristics, enabling design flexibility and lighting adaptability while treating only the necessary portions.

The patent changes optical parameters (transparency, color) of the raw plate by applying thermal treatment at controlled temperatures. By adjusting temperature and treatment duration, different optical properties are achieved in treated sections, allowing the same raw plate to be adapted for various lighting configurations and design requirements.

The patent segments the customization process from the mass production process. Raw plates are produced in bulk with standard properties, then later divided into treated and untreated sections through thermal treatment. This allows efficient mass production of base materials while enabling subsequent individual customization without affecting the initial manufacturing efficiency.

The patent performs preliminary mass production of raw plates with uniform properties, then applies selective thermal treatment as a subsequent action. This preliminary production of standardized components maintains manufacturing efficiency, while the later thermal treatment step enables individual customization when needed.
