A clean technical blueprint-style exploded diagram of [a tennis racquet and ball], formatted like an instruction manual figure. Canvas and Composition: Vertical 3:4 portrait layout set against a [warm off-white] paper background with ample negative space. Features thin [cobalt blue] line art, monoline technical drafting strokes, subtle paper texture, and pale blue translucent fills where appropriate. No shadows, except for a flat soft blue shading on the ball core. Layout: - Left two-thirds: The exploded racquet arranged vertically along a central axis with visible separation between parts. - Right-middle: The exploded cross-section of the tennis ball. - Construction lines: Dashed vertical guide lines framing the assemblies and dashed horizontal callout lines leading directly to labels on the right side of each component. - Lettering: Crisp, monospaced blueprint all-caps font. Header and Footer Annotations: - Top-left corner: "[FIG.002]" - Top-right corner: "[ RACQUET AND BALL ]" - Bottom-right corner: "[COPYRIGHT 2026]" Visible Components (13 total): Racquet assembly (7 parts stacked top to bottom): 1. FRAME: Oval head rim with evenly spaced string holes and yoke junction. 2. STRING BED: Separate dense crisscross mesh insert with perimeter tie-off nodes. 3. THROAT: Open triangular bridge piece. 4. SHAFT: Cylindrical connector with inset recess. 5. GRIP: Tapered cylindrical handle wrapped in spiral bands. 6. BUTT CAP: Hexagonal base end cap. 7. Dashed vertical alignment axis and callout lines. Ball assembly (6 parts): 1. Top curved white FELT shell. 2. Central blue spherical CORE with contour line. 3. Bottom curved white FELT shell. 4. Dashed vertical guide lines. 5. Dashed callout line pointing to FELT. 6. Dashed callout line pointing to CORE. Callout Labels: Exactly 7 blue uppercase labels aligned to the right of each section: FRAME, STRING BED, THROAT, SHAFT, GRIP, BUTT CAP, FELT, CORE. Style: Minimalist technical patent schematic, precise vector drafting geometry, no photorealism, no human figures, no background scenery.
