Make “Notebook Cutaway Device Diagram with Blue Labels” yours

Create a vertical hand-drawn engineering-science infographic on the theme «Components of [topic]». The background is a warm-white, slightly yellowed lined notebook page with light-blue horizontal rules, a pale-red vertical margin line on the left, preserving fine paper fibers and a slight scanned texture. At the top center, write a large handwritten title in blue ballpoint pen «[Chinese title]», with a slender, rounded, neat font, and draw a blue hand-drawn underline beneath the title. In the center, place a large [device name] in a slightly top-down three-quarter perspective, showing the internal structure partially opened, in cutaway, or disassembled. The structure should follow real engineering logic, with parts clearly layered and easy to identify. The main subject uses a fine graphite-pencil engineering illustration style: dark-gray thin outlines, dense hatching and cross-hatching to build volume, metal surfaces with realistic matte finish, reflections, and mechanical texture. Overall dominated by gray-black, with only a few restrained touches of yellow, red, and blue colored pencil on copper wires, circuits, coolant, and cables. Keep natural hand-drawn lines and slight imperfections. Around the subject, arrange [number] numbered Chinese labels, all in the same blue ballpoint handwriting, with thin straight blue arrows precisely pointing to the corresponding parts. Labels must not cover the device, arrows must not cross each other, layout balanced left and right, with natural whitespace. Label content: 1. [part name] 2. [part name] …… At the bottom, write 2 to 3 short lines of principle explanation in the same blue handwriting: «[explanatory text]» The overall effect should look like class notes carefully drawn by an engineering student: technically accurate, rich in detail, realistic yet handmade, with a neat layout, clear information, and a natural scanned texture.
