Hi — this is Mohand, a talented mechanical engineer based in U.S. engineering. I’m excited about the opportunity to design your metal porch door lock prototype for a child-safe screen door. I can develop a rotating metal arm mechanism that secures the door from both sides, using a metal dowel through the jamb with an interior knob and an exterior arm that rotates in front of the door to block it and up to clear it. My workflow in SolidWorks allows me to create a clean, functional 3D model optimized for metalworking and 3D-printed test parts. I will focus on simple, reliable operation, robust geometry, and easy installation while keeping child safety as the top priority. I can provide detailed CAD files, assembly drawings, and a prototype-ready design that you can refine or fabricate directly. Please share any dimensions or constraints you have, and I would be glad to start right away.

Hello, I have extensive experience designing mechanical prototypes, safety mechanisms, and functional hardware assemblies with a focus on reliability, usability, and manufacturability. I’ve worked on moving components, locking systems, metal mechanisms, and product concepts requiring precise fit, durable materials, and practical operation. For your screen porch door safety lock, I will develop a functional CAD prototype with the rotating metal arm, through-door dowel system, interior knob, and exterior blocking mechanism integrated into a simple and robust design. The model will consider assembly method, user operation from both sides, material selection, and prototype fabrication requirements. Could you provide the door thickness, frame dimensions, and any existing lock hardware constraints? Also, should the prototype prioritize CNC machining, 3D printing for testing, or direct metal fabrication? Regards

Right from the start, I want to assure you that choosing me for this project would be a wise and strategic decision. Firstly, I'm a Mechanical Design Engineer with a lot of experience and proficiency in prototyping complex mechanical locks and mechanisms. This encompasses your requirement for a rotating metal arm design that can be operated from both sides – my specialty. Another tick in my box is my extensive knowledge of SolidWorks, which will allow me to deliver highly-detailed design files like SLDPRT / SLDASM, STEP / IGES / DXF and STL / OBJ on top of technical drawings. Coming to manufacturing, I've been trained with the DFM (Design-for-Manufacturing) principles, ensuring the lock mechanism we create together not only excels functionally but also maximizes its effectiveness on the production line. Lastly, though by no means less important – my commitment to professional communication, reliability, and on-time delivery. Being a freelancer for a variety of clients over the years has sharpened my soft skills as much as my technical capabilities. I'd see our collaboration more as a partnership aiming to achieve one common goal – realizing your vision of a child safety lock prototype for your porch door. Thank you for considering me – now let's revolutionize child safety together!
