The prompt
Create a clean, simple, realistic 3D CAD-style isometric render of a compact square hybrid energy-harvesting floor tile for human footsteps. The device is a small square platform, approximately 25 cm by 25 cm, with a very low total height of less than 3 cm. It must have two flat square wooden boards: a lower rigid MDF base and an upper blue semi-transparent acrylic or painted MDF stepping plate. The upper stepping plate floats above the lower base using four visible metallic compression springs positioned near the four corners. Each spring is vertically aligned, evenly spaced, and supports the upper plate. Include small bolts, washers, and nuts around the springs to make the platform look mechanically solid and buildable. Inside the space between the top and bottom plates, show a complete hybrid energy-harvesting mechanism: - Sixteen small circular piezoelectric discs arranged symmetrically in a 4 by 4 grid across the wooden base. - The piezoelectric discs must look like small round brass-gold metal discs with pale ceramic centers. - Add small dark rubber or EVA pads above the piezoelectric discs, positioned between the discs and the upper plate. - Place a compact low-profile electromagnetic generator at the center of the tile. - The electromagnetic generator consists of a short gray PVC cylinder, a tightly wound copper-colored coil around the cylinder, and a small cylindrical neodymium magnet positioned inside the PVC tube. - The magnet is attached to the underside of the upper plate by a short central rod, so it moves vertically when the top plate is pressed. - The coil remains fixed to the lower wooden base. - Include simple red and black wires routed neatly along the base from the piezoelectric discs and coil toward one small green circuit board near an edge of the base. - The small circuit board should contain only basic electronic parts: tiny black diodes, one small cylindrical capacitor, a red LED, and a small connector. Show the upper plate slightly raised above the base, with a narrow air gap of approximately 2 to 4 mm. The design must look sturdy, low-profile, compact, easy to assemble by beginners, and made from accessible parts: MDF wood, acrylic, steel springs, bolts, piezoelectric discs, PVC, copper wire, neodymium magnet, red and black cables, and a small circuit board. Composition: - Isometric three-quarter view from slightly above. - White or very light gray studio background. - Soft shadows. - Product visualization / simple engineering prototype style. - Realistic materials and proportions. - The internal components must be visible through the semi-transparent blue top plate or through a subtle cutaway. - Keep the geometry simple and clean. - No people. - No hands. - No logos. - No text. - No labels. - No dimensions. - No arrows. - No annotations. - No floating exploded parts. - No complex gears, motors, batteries, or industrial components.
