Understand
Define the problem
Clarify requirements, constraints, interfaces, intended use and the technical problem the design must solve.
Develop
Build the solution
Develop the mechanical architecture, CAD geometry, assemblies and design details needed to transform the concept into a functional system.
Validate
Evaluate and refine
Review fit, motion, structural behavior, manufacturability and prototype feedback to identify improvements before finalization.
Prepare
Prepare for fabrication
Refine the approved design and organize the technical deliverables required for prototyping, manufacturing or further development.
