Mechanical Design is a discipline of engineering that focuses on applying a combination of physical principles, mathematics, and materials science on the design, assembly, and maintenance of mechanical systems. The area often encompasses the development and analysis of both individual components and complete systems ranging from an entire car engine to smaller parts such as gears, levers, bearings, springs, hinges and other small mechanical parts. Mechanical Engineers use the knowledge and skills acquired to research, design, develop and test machines, engines and other types of tools for different industries. In essence, Mechanical Engineers create solutions that keep people and processes safe.
When working on projects for clients, hiring a Mechanical Engineer is beneficial for many reasons. A Mechanical Engineer offers expertise across multiple areas - engineering design skills to identify potential issues with existing systems or to develop new ones; problem-solving skills when it comes to resolving problems; knowledge in material sciences used in designing products; and the ability to develop detailed plans when implementing or maintaining systems.

I am building DigitScale IA, a dedicated body-composition scale that goes beyond mere weight and zeroes in on bone density. The goal is a standalone hardware device—complete with its own enclosure, sensing module, firmware and simple companion interface—that can provide reliable, non-invasive bone-density readings each time a user steps on it. Your expertise in sensor selection, PCB design, firmware development and calibration will shape the entire product. Feel free to propose capacitive, impedance-based, ultrasound or hybrid approaches; accuracy and repeatability are the metrics that matter most. Bluetooth LE connectivity is preferred so users can pull their data into a mobile app later, but a basic on-device display will suffice for the first iteration. Deliverables &b...
We manufacture washroom cubicles and need an experienced CAD drafter who can jump in at short notice. For every project I will send you the layout, panel dimensions and hardware details. Your job is to turn that information into: • Client sign-off drawings – clean, clearly annotated PDF sheets produced in AutoCAD • Manufacturing packs – one DXF and one STP file per panel, plus a compiled PDF set for workshop reference All files must originate from AutoCAD so that my internal team can edit them later if required. Accuracy is critical; hole centres, edge bands and any special cut-outs must match the information I provide. I have attached a completed project as a template so you can see layering, title-block style and the level of detail expected. If you are comfo...
I need an experienced SolidWorks specialist to take full ownership of multiple flatbed trailer projects. Every model must optimize load capacity, stand up to heavy-duty use, and make loading or unloading as straightforward as possible. All trailers will be steel-constructed, so please be comfortable specifying beam sizes, weld details, and connection hardware for this material. Typical deliverables include the complete 3D model, detailed fabrication drawings, BOMs, and any strength or clearance checks you normally run for road-worthy equipment. This is not a one-off task—our workload is continuous. If your first design meets our quality and manufacturability standards, you can expect a steady stream of trailer assignments. When you respond, show me at least one prior flatbed...
I already have concept videos and rough sketches for a fully automatic case-packer / cartoning machine that collates boxed products (secondary packaging) and inserts them into shipping cases. What I need now is a complete mechanical design inside Autodesk Inventor so the build team can take it straight to the shop floor. Using Inventor, please create a parametric 3D assembly that respects normal industrial footprints; there are no unusual size constraints beyond keeping the layout practical for a standard production line. The model should include every mechanism—product in-feed conveyor, collation system, pick-and-place or push station, case magazine, flap closing units, guarding, drives, and frame. I will supply all reference videos, the current layout, and supplier data for purcha...

I am looking to create a complete, professional assembly jig design for the rear fuselage side plate/panel of a generic aircraft. The freelancer will need to design the entire jig from scratch, starting with research on standard practices for fuselage panel assembly fixtures, then creating the full 3D model, drawings, and documentation in CATIA V5. The jig should hold and locate the curved/contoured side panel accurately during assembly (e.g., riveting/fastening stringers, frames, or skin panels), ensuring precise alignment, minimal deformation, and repeatability. Design the full jig assembly: Base/frame structure (beams, plates, supports). Locators (pads, pins, vee-blocks, or adjustable for curvature). Clamps (toggle, swing, or vacuum if suitable). Additional supports to control panel d...

Summary We are developing a perfusion lid system for a proprietary vertical-membrane co-culture plate used for advanced cell culture. The lid will enable controlled flow (shear) along the membrane and will scale to the full plate with 12 independent recirculating loops (one loop per column). Each column contains 8 wells (total 96 wells). We prefer 12 independent loops so each column can run different flow rates and/or media conditions. We are looking for a contractor who can support development (concept → CAD → prototype strategy → DFM), not just drafting. We want flow constrained into a defined gap near the membrane to generate predictable laminar shear Target design gap: ~0.3–0.5 mm (must be toleranced and verifiable) Typical target per-well flow range: ~30–20...
I need a complete engineering design for a sonic soot blower dedicated to a water-tube boiler. The main driver is to prolong the unit’s service life by keeping the economizer section consistently clean without resorting to abrasive or high-pressure mechanical methods. Here’s what I’m looking for: • A properly sized acoustic horn (frequency, SPL, nozzle geometry) that is effective on the economizer’s finned tubes. • Integration details—mounting arrangements, air supply specs, control logic—and confirmation that the new equipment will fit around existing access doors and ducting. • Supporting calculations or CFD evidence showing ash/soot detachment rates versus current steam-soot-blowing performance. • Fabrication drawings, 3D m...

I’m finishing a custom guitar case and need a purpose-built handle that can survive the rigours of touring while feeling great in the hand. The brief is straightforward: • Core material: metal for maximum strength and longevity. • Grip: must be rubber-coated or knurled so it stays comfortable and non-slip even when hands are sweaty. • Attachment: the handle will be screwed to the Carbon Fiber composite case walls; the design therefore has to include proper load-spreading plates or inserts, accurate hole alignment and hardware selection. What I need from you: 1. Concept sketches that explore shape, ergonomics and aesthetics in line with classic guitar-case styling. 2. Full 3D CAD (STEP/SolidWorks preferred) with stress considerations for a 25 kg load. 3. Manuf...
Note - I want someone to make & get one machine ready for me so please bid if you can handle everything from design to manufacturing. I am developing a compact, battery-powered device that continuously feeds a roll of sticky mat across a doorway so the exposed surface always stays clean. The concept is simple: a fresh section of mat is pulled from one spindle, laid flat, and the used layer is wound onto a take-up reel. Here’s what I already know I want: • Time-based automatic control that advances the mat precisely every hour. • A low-profile, walk-safe deck suitable for hospital corridors and dusty construction entries alike. • A rigid steel frame for durability, yet light enough to remain truly portable. • Quiet, sealed gear-motor driven by a rec...
I am looking for a skilled graphic designer or 3D artist to create a realistic before-and-after comparison image for a crowdfunding campaign. This project is based on a real existing cemetery urn wall i (Netherlands) which inspired an innovation idea. The image will be used to explain the concept visually without revealing technical details. I already tried generating the images with AI (Leonardo AI and other tools), but the results are incorrect and unrealistic. The AI keeps producing wrong angles, loose stones, pots placed on top, or unrealistic mounting systems. Because this image is important for crowdfunding, I need a professionally made and accurate visualization. Goal of the Image The final image must show: LEFT SIDE – BEFORE (Current Situation) A realistic cemetery urn...
