The prompt
Act as a senior mechanical design engineer, HVAC engineer, industrial designer and manufacturing engineer with more than 30 years of experience. Design a premium motorized smart air vent (HVAC supply grille) that can be manufactured with injection molding and standard mechanical components. Overall dimensions: Length: 500 mm Width: 300 mm Depth: 200 mm The design must include: 1. Dual-axis airflow control. - Vertical louvers rotate up and down. - Horizontal louvers rotate left and right. - Both movements can operate independently or simultaneously. 2. Airflow volume control. - An internal damper gradually adjusts airflow from 0% to 100%. - It must also completely close the airflow. 3. Actuation. - Use compact DC geared motors or miniature stepper motors. - Hidden motor installation. - Quiet operation. - Low power consumption. - Long service life. 4. Transmission. - Design gears, shafts, connecting rods and linkages. - Minimize number of parts. - Easy assembly. - Easy maintenance. 5. Manufacturing. - Suitable for plastic injection molding. - Standard screws only. - Standard bearings and shafts. - Avoid unnecessary machining. - High structural rigidity. 6. Appearance. - Premium modern HVAC style. - Thin bezels. - Hidden fasteners. - Elegant professional appearance. 7. Deliverables. Provide: A. Full 3D CAD model. B. Exploded view. C. Assembly drawing. D. Detailed part drawings. E. BOM (Bill of Materials). F. Assembly sequence. G. Cross-sectional views. H. Internal mechanism animation. I. Motion simulation showing: - Up/down movement - Left/right movement - Damper opening 0–100% - Full closing J. Engineering calculations: - Required motor torque - Gear ratio - Estimated airflow - Pressure loss - Material recommendations K. Manufacturing recommendations. L. STL, STEP and DWG export. The design should prioritize: - Simplicity - High elegance - Low manufacturing cost - Easy maintenance - Reliable operation - Commercial production readiness - Minimal number of parts - Professional engineering quality.
