No Fixed Number of Days. The Cycle Depends on Clarity of Requirements, Category Complexity, Certification Constraints, and Decision Efficiency, Not Just "Drawing Speed".

Common Range (For Reference Only)

Relatively simple consumer hardware appearance direction: reviewable solutions in weeks.

Products with Complex Structures, Multiple Assemblies, or Strict Certifications: Need to Be Stretched by Stages, with Reserved Prototypes and Modification Rounds.

Variables Controlled by Clients

Whether decision-makers are present, whether requirements are frozen, whether feedback is specific (not just "make it more advanced").

Providing competitor analysis, cost ceilings, mandatory certifications, and target launch dates can significantly reduce idle time.
