Industrial Design Concept Generation

I am looking to develop an industrial design concept for a modular clip-on attachment for a conventional endoscope handle. The concept should visually explore a compact, ergonomic device that mounts over the existing endoscope control wheels and assists their movement through a motorised or mechanical drive system, potentially controlled by a joystick or intuitive external controller.
I need concept sketches/renders that show the attachment fitted onto an endoscope handle, highlighting form, ergonomics, mounting method, control interface, and overall product styling.
