The prompt
Create a realistic 3D CAD engineering design of a 14-inch BLDC pedestal fan with a 360° spherical nutation mechanism, inspired by US6506012B2 FIG.6. Mechanical Structure: * Fixed outer hemisphere: Connected to the rear cover, support pole, and base. * Moving inner hemisphere: Supports the entire fan head, including the grille, BLDC motor, and blades. * Spherical bearing: Provides a fixed pivot for smooth multidirectional tilting. * Eccentric drive: A compact geared motor and eccentric bearing generate continuous 360° conical oscillation at a 15° tilt angle. * Anti-rotation guide: Prevents the inner hemisphere from spinning around its own axis. * Fan blades: Rotate independently at high speed, while the grille follows the slow oscillating motion. Visualization: Show three detailed views: 1. Fully assembled 3D mechanism. 2. Exploded mechanical assembly. 3. Enlarged cutaway showing the spherical bearing and eccentric transmission. Use a professional SolidWorks-style CAD rendering with realistic mechanical connections and color-coded components. Design Goals: Minimal parts, compact structure, low noise, low vibration, high durability, and easy manufacturing. Avoid unnecessary gears, complex linkages, floating components, or unrealistic mechanical structures. Result: A clean, technically plausible 3D engineering concept with clearly visible internal transmission principles.
