The prompt
Design a compact mechanical assembly for an automotive active aero system that fits within a maximum envelope of 3 inches vertical depth. The assembly consists of: A rigid carrier platform that raises vertically from a vehicle decklid. A fixed center wing section mounted to the carrier. Two independent outer wing sections mounted on left and right linear slides. Each outer wing translates horizontally outward from the center after the carrier is fully raised. After deployment, each outer wing must rotate independently about its spanwise axis to vary angle of attack for aerodynamic control and air-brake functionality. Design only the mechanical architecture. Requirements: Compact packaging. Independent left and right operation. High rigidity under aerodynamic loading. Mechanical hard stops for deployed positions. Minimize backlash. Serviceable modular construction. Bearings and pivots sized for automotive duty. Leave actuator selection unspecified. Explore mechanisms including: Four-bar linkages Cam-driven rotation Over-center locking Sliding carriages Deployable wing pivots Kinematic linkage solutions Primary objective: Create the simplest mechanism that allows: Carrier rises. Side wings extend horizontally. Side wings tilt independently. Mechanism retracts in reverse. Do not design exterior styling. Produce only the internal mechanical concept suitable for CAD refinement and manufacturing.
