Mechanical Mechanism Design

Need a functional mechanical mechanism designed for your product, machine or equipment? I can develop individual components and integrate them into a complete working mechanism.

I focus on the movement, component interaction, clearances, assembly and manufacturability of the mechanismnot just its visual appearance.

What I can design:

  • Linkage mechanisms
  • Sliding and linear mechanisms
  • Cam and follower mechanisms
  • Gear-driven mechanisms
  • Shaft and coupling systems
  • Clamping and locking mechanisms
  • Lifting and positioning mechanisms
  • Rotary and reciprocating mechanisms
  • Custom mechanical mechanisms
  • Machine sub-assemblies

What you can receive:

  • Individual 3D CAD components
  • Complete mechanism assembly
  • Motion and interference checking
  • Exploded assembly view
  • BOM
  • Engineering/manufacturing drawings
  • Dimensions and tolerances
  • GD&T where required
  • STEP / IGES / STL files
  • Native CAD files and PDF drawings

I consider kinematics, clearances, component interaction, load requirements, assembly sequence and manufacturing feasibility while developing the mechanism.

You can provide a concept, sketch, reference mechanism, video, dimensions or functional requirements, and I

I’m a Mechanical Design Engineer with 3 years of experience in machine and product design. I specialize in SolidWorks, AutoCAD, 3D CAD modeling, mechanical assemblies, sheet metal design, GD&T, manufacturing drawings, and reverse engineering. I have hands-on experience with CNC cylindrical grinding machines, machine components, mechanisms, and manufacturing projects. I focus on creating accurate, functional, and manufacturing-ready designs with proper fitment, clearances, and assembly considerations. Let’s turn your idea into a precise engineering solution.
