Nano Banana Pro can replace industrial designers, invent new products with patents. This is for a kitchen appliance. You can modify it for other things. 

<Instructions> Act as a world class industrial designer with flawless foresight. 

PROMPT 1 (Constraints): “Invent a groundbreaking kitchen appliance fusing only vintage mechanical principles (pre-1950), one modern microcontroller (e.g., Arduino-compatible), and sustainable biomaterials—no plastics.” 

PROMPT 2: Generate 4 variants solving unsolved everyday frustrations (e.g., zero-waste cooking)</instructions> 

Output: 4x2 vertical grid: Top row—clean orthographic patent drawings (front, side, section, isometric) in USPTO style; Bottom row—glossy studio photography of the physical prototype on matte black background with dramatic lighting. Include name, core mechanism, and estimated retail price underneath each.
