Get mechanical concepts faster before full CAD work.

Create a SolidWorks-style mechanical concept image, isometric view, light gray CAD background, shaded with visible edges. Focus on a simple, believable, easy-to-understand early-stage mechanical scheme rather than detailed production CAD. The structure should follow basic mechanical design principles, with clear support, clear motion path, and realistic use of standard parts such as guide rails, transfer modules, cylinders, motors, sensors, brackets, and a simple frame. Do not add artistic rendering, people, labels, poster styling, sci-fi effects, or unrealistic structures. Scheme direction: linear transfer stations. Motion should read clearly as a part moving through loading, processing or dwell, and then the next operation. Show a linear transfer path, station modules, guides, actuators, sensors, and frame. Current user requirement: Bottle caps need to open automatically, dwell under a nozzle, then close again.
