Hộp Sa Bàn Mặt Cắt Cơ Khí

A detailed physical cutaway diorama box resting on a wooden workbench, revealing the inner mechanical layers and cause-and-effect process of [an automated vintage coffee roasting and brewing system]. The boxed cross-section displays stacked architectural floors: raw material intake, brass pipes and mechanical gear sorting, storage bins, conveyor belts transporting miniature tokens, and final packaging chutes. Physical flow cues connect the stations using painted guide tracks, taut string lines, and marble-run pathways. Tiny toyified miniature worker figurines in roles like operator, inspector, and analyst interact with miniature levers and switchboards. Pinned to an interior wooden wall is a tiny stamped paper certification notice. A small failure corner shows a jammed belt mechanism, contrasted with an adjacent reinforced upgrade corner. Three-quarter perspective view, crisp depth of field, soft practical workshop lighting with gentle tactile shadows, crafted from wood, brass, matte resin, and paper. No holograms, no neon, no bioluminescence.
