black-and-white technical line drawing
Task
Convert the attached photo into a black-and-white technical line drawing suitable for a USPTO patent figure.
Framing & scale
• Present a wide shot of the entire object, centered on a pure-white background.
• The object must occupy no more than 60 % of the canvas in both width and height, leaving at least 20 % blank white margin on every side for future annotations.
• Keep the object’s flat front view orthographic and proportions exactly as in the photo—do not rotate, skew, or alter its geometry.
Style & execution
• Clean, minimal, vector-style line art only.
• Uniform stroke weight; high-contrast black lines on white; absolutely no shading, color, textures, or background elements.
Detail fidelity
• Reproduce every visible mechanical or structural feature: edges, contours, holes, fasteners, seams, surface transitions, etc.
• If any portion is obscured or out of frame, terminate the geometry cleanly—do not invent or infer unseen details.
Negative constraints
• No close-ups, cropping, zoom-ins, or artistic reinterpretation.
• No added features, embellishments, or background objects.
Output requirement
A single high-resolution image that reads like a traditional cad drawing view: crisp lines, consistent stroke thickness, generous white space, ready for annotation.
