I need to turn a new product idea into a solid conceptual mechanical design. The focus is on early-stage product definition: form, basic kinematics, key components, preliminary materials, and rough manufacturing considerations. Once the concept is approved, I plan to move into detailed engineering in AutoCAD, so any files or sketches you create should transition smoothly into that environment. Deliverables I expect for this phase: • 2-3 refined concept variants presented as 3D visuals or annotated sketches • A short design rationale outlining assumptions, mechanisms, and proposed materials • Native files plus neutral formats (STEP, IGES or PDF) suitable for later AutoCAD work Please factor in one review cycle for tweaks before finalizing the chosen concept.
