Mechanical Design Jobs

I’m putting together a simple proof-of-concept: an XY plotter that uses stepper motors and a motor-driven cream / syringe head to write one predefined word on plain paper in four different sizes. The word and the sizes will be hard-coded for now; no live UI or font selection is needed. I just want to see smooth, accurate motion, clean cream extrusion, and clearly legible lettering in an “Elegant” style. Here’s what I need from you: • Mechanical design and parts list for the XY frame, rails, carriage, and syringe mount, all sized for an A4 sheet of paper. • Electronics schematic and firmware (Arduino + GRBL, or any open-source control stack you prefer) that drives two XY stepper motors plus a third actuator for the syringe. • G-code or equivalen...

I need a modular box unit designed for controlled environment agriculture, specifically for growing herbs using vertical farming techniques. The unit should be adaptable for various growing conditions and efficient in space utilization. Key requirements: - Must support vertical farming systems - Suitable for herb cultivation - Modular design for scalability - Climate control integration Ideal candidates should have experience in agricultural design, especially in vertical farming.

Product Design / Mechanical Engineer Needed – Portable Pet Product We are a UK start-up developing an innovative portable outdoor product for dog owners and are looking for an experienced Product Design / Mechanical Engineer to help refine our existing concept and prepare it for prototyping and manufacture. The product concept, branding and initial CAD/design work have already been developed. We have also carried out initial market research with UK dog owners, which has identified several areas we would now like to improve from an engineering and usability perspective. The Project: The product is a compact, portable shade and comfort station for dogs, designed for use at beaches, parks, camping trips, outdoor events, holidays, gardens and other outdoor environments. The current ...

I already have a clear concept and now need it turned into a production-ready mechanical design in SolidWorks. The job is firmly in the detailed-design phase: every part must be modeled, toleranced, and fitted into a complete assembly that a manufacturer can quote from without guesswork. I will share sketches, functional requirements, and any reference models I have. From there, I expect you to build the full SolidWorks project, keep the feature tree clean, and follow best-practice naming so future edits are easy. To make expectations crystal-clear, here is what I need back: • Native SolidWorks 3D part and assembly files • Fully dimensioned 2D drawings for each component and the overall assembly • Exploded views and a BOM with material specs and quantities • A ...

We are looking for an experienced Mechanical/Industrial Engineer specialized in SolidWorks or similar CAD software to design a reusable steel mold for the mass production of precast concrete housing modules. The concrete module is approximately 3.0 m wide × 7.0 m long × 3.0 m high, open at the top, with an additional 1.2 m balcony on the front side. Main concrete specifications: * Wall thickness: 80 mm * Floor thickness: 200 mm * 4 concrete walls + floor cast as one monolithic piece * No roof during this casting process We need the complete manufacturing design of the steel mold, including: * External steel formwork * Internal negative/core mold * Steel plate thickness calculation * Structural frames and reinforcement ribs * Corners, connections and locking systems * Openi...

I need a mechanical engineer who can guide me in choosing a fixed-ratio gearbox for an industrial machine now in the design phase. The gearbox will not be manual, automatic, or CVT; I specifically want a robust fixed gearbox that can meet three critical criteria: high load capacity, a defined speed range that matches our motor curve, and long-term durability in a 24/7 production environment. Your task is to analyse the duty cycle, calculate the required service factor, and translate those figures into an exact gearbox size and model recommendation. Please include: • All design calculations and assumptions • A shortlist of commercially available gearboxes that satisfy the numbers, with supplier links and lead times • A brief comparison explaining why the recommended uni...

I'm looking for a CAD designer to create a machine tool specifically for pinching water hoses (layflat of 16” diameter). The design should prioritize ease of use. Key Requirements: - Design a machine tool for pinching 16” diameter water hoses. - Focus on ease of use in the design. Ideal Skills and Experience: - Proficiency in CAD software. - Experience in designing machine tools. - Strong focus on user-friendly design principles. Please provide examples of similar work.

I’m designing a slow-turning drum and need an experienced engineer to specify both the AC motor and the reduction gearbox that will drive it. The drum must rotate steadily at 6 RPM and the load calls for less than 100 Nm of torque on the output shaft. Space is limited, so overall package size and mounting arrangement have to be considered alongside efficiency and durability. What I need from you is a clear, calculation-backed recommendation: the appropriate gear ratio, motor power, frame size, and any duty-cycle or thermal considerations that might affect service life. Please base the sizing on readily available industrial components—ideally IEC-frame or NEMA equivalents—so I can source them quickly. Deliverables • A brief sizing report showing assumptions, torqu...

I need a complete mechanical design package for four identical 800 mm-wide belt conveyors that will carry bulk materials in an outdoor setting. I will supply the full layout and dimensional data; your task is to turn those numbers into ready-for-fabrication documents. Because these units will be exposed to the elements and loaded with bulk product, reliability and maintainability are critical. All three idler styles—troughing, return and impact—must be incorporated, along with properly sized pulleys, a robust take-up arrangement, and a drive system that aligns the motor, gearbox and coupling without shimming on site. The steel structure, galleries or trestles should be checked for deflection and vibration against standard limits. Deliverables I expect: • Detailed 3D mode...

A functional medical equipment product is already on my bench; what it lacks is a visually inviting shape and form that makes people want to pick it up and use it. I need a mechanical design engineer who can re-imagine the external geometry while respecting the internal components and overall ease-of-use goals. The brief is centred on aesthetic enhancement—specifically refined contours, balanced proportions, and a smooth user interaction—without compromising mechanical integrity. The workflow I picture is straightforward: translate my sketches and rough CAD into elegant 3D models, review iterations together, then prepare manufacturable files. Experience with SolidWorks or Fusion 360 is essential, and an eye for ergonomic detail will set the direction. Deliverables • Op...

I'm looking for a skilled material engineer or specialist to create a 12-inch urethane hinge for a small sailboat rudder. This hinge will need to withstand high-stress conditions and is intended to replace an old, degraded hinge that turned into a slippery goo after 20 years. Key Requirements: - The hinge must be durable, specifically designed to resist cracking, deforming, or detaching under stress. - It should withstand exposure to water without degrading. - Ideally, you should have experience with high-performance materials, particularly urethane or similar polymers. Please provide samples or evidence of previous work with high-durability hinges or similar applications. Thank you!

I have a working prototype of a transverse dental floss holder with a thumb-operated mechanism to tighten floss for insertion between teeth and slacken it for cleaning them. Key requirements: - Material: Plastic - Compatibility: Both waxed and unwaxed floss - Tension variation: Push button mechanism, preferably tightening floss by more than 10mm achieved by prototype - Ease of threading floss through the mechanism, which may require hinged case Ideal skills and experience: - Experience with plastic molding or fabrication - Familiarity with dental care tools - Mechanism design expertise, especially push-button systems
