A detailed technical illustration of a modern toilet seat prototype. The toilet seat is upright in its resting position using a torsion spring mechanism hidden in the rear hinges. The seat is connected to the spring with small metal attachments. The lid has a magnetic closure at the front to keep it securely shut while flushing. The toilet is white porcelain, the seat is slightly raised and shown semi-transparent to reveal the spring mechanism inside. The hinges, spring, and magnetic components are clearly visible, with labels or callouts for: torsion spring, hinge, magnet, seat, and lid. The style is a clean schematic drawing, engineering diagram, high detail, clear lines, neutral background, professional presentation, realistic proportions. Show the seat both in the upright resting position and slightly lowered to demonstrate movement. Include arrows showing upward motion of the seat from spring force. Lighting is soft, shadows subtle, focus on mechanical design. Mehr sehen
