My goal is to take several upcoming Mechanical, Electrical and Plumbing scopes from the first sketch straight through commissioning and hand-over. I therefore need seasoned, end-to-end guidance that covers every decision point—concept design, detailed calculations, drawings, equipment selection, code compliance, procurement, installation sequencing, testing, and final close-out. The assignment spans all three disciplines, so I will rely on you to align ductwork, power distribution and piping layouts into one fully coordinated package, flag clashes early, and help optimise energy, water and maintenance costs. Because this is an A-to-Z brief, I expect practical advice on site logistics, contractor coordination, scheduling and quality checks in addition to the core engineering work. T...

I am working with the Maxim MAXREFDES103 optical health-sensor board (21.4 × 17.0 mm) and already have a complete engineering brief that specifies every component, footprint, and trace requirement for the next hardware spin. Your task is to open the native Cadence Allegro .brd file, add three additional LED channels, and replace the existing photodiode with the upgraded part exactly as called out in the documents. Key context • Placement: the brief marks preferred zones for the new LEDs; you may adjust within those areas to achieve clean routing and keep impedance targets intact. • Sourcing: I normally buy through DigiKey and Mouser, yet I am happy to accept equivalent parts from other reputable distributors if availability dictates. • All stack-up, SDS geometry...

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 rechargeable ...

Please deliver production-ready 3D CAD files (STEP or IGES), exploded assembly views, a short bill of materi...

I'm looking for a mechanical engineer. I have the CAD plans for a functional robot ready, but before I manufacture the first batch I want to simplify its production. I am looking for a mechanical engineer to review and optimize the schemes with the following main objectives: Facilitate team assembly. Increase the durability of key parts. Reduce the overall cost of manufacturing. The area that most needs improvement is the movement system (engines, transmissions and supports). In addition, in the external housing I need the number of parts to be assembled to be as minimal as possible without compromising rigidity or aesthetics. Deliverable I hope: 1. Updated CAD models (SolidWorks, Inventor or equivalent) with proposed modifications. 2. Revised and optimised Materials List (BOM) wit...

I am modelling a single-segment continuum robot whose backbone is manufactured in polyurethane and ABS. Your task is to set up and run parametric finite-element studies in ANSYS so we can see how the structure curves when one tendon is pulled with forces in the low 1 – 10 N range. For each geometric variant of the backbone I will supply (length, diameter, tendon-channel offset, bakbone type etc.), I need two clear results: • the exact tendon force applied, and • the resulting bend curvature radius of the backbone. Once all variants are simulated, please compare the force-radius trends and point out which configuration gives the most favorable bending performance so I can move forward with an optimal design. Deliverables must include the editable ANSYS project files, any ...

I am seeking an experienced mechanical or FEA engineer to perform a static structural finite element analysis (FEA) on a plastic lid component made from Polycarbonate (PC-110). The goal of the analysis is to estimate the force required to cause yielding or failure when a load is applied at the center of the lid panel. A STEP file of the part and a detailed instruction PDF are attached here. The simulation should apply a load perpendicular to the lid surface over a 1-inch diameter circular area at the center, while the perimeter of the lid is constrained as shown in the attached instructions. The analysis should gradually increase the load until material yield occurs (Von Mises stress ≥ 9,000 psi). Deliverables should include a short simulation report (PDF), stress plots, deformation plo...

I need a complete engineering package for a mobile shredder that turns mixed vegetable waste into 3-5 cm pieces and then compacts it with a built-in hydraulic press. The machine must comfortably handle 50–200 kg of material per day and be light enough to move around the farm on a small trailer or skid. Core requirements • Cutting system sized for fibrous, high-moisture vegetable matter; knives or hammers should minimise clogging and be easily replaceable. • Consistent particle size of 3–5 cm without excessive fines. • Integrated hydraulic ram (manual, electric, or engine-driven—justify choice) that compresses the shredded output into manageable bales/blocks. • Power options: single-phase 230 V, small diesel/petrol engine, or tractor PTO—...

I’m running a steady-state, two–phase condensation model for a single steam-carrying tube placed inside a rectangular duct through which the cooling medium flows. The goal is to quantify heat-transfer efficiency along the tube wall and map local condensation behaviour. All pre- and post-processing must be done in ANSYS Fluent – that is the environment my wider workflow depends on. I already have basic geometry and material data; what’s missing is a robust setup that captures phase change, solves for the temperature field on both sides of the tube, and outputs wall heat-flux, overall U-value, and condensate distribution with mesh-independent accuracy. Key points • Physics: two-phase (steam → liquid) condensation, steady-state, turbulent flow inside and ...

I am ready to move my mechanical wheel-end assembly from a rough concept to a fully filed U.S. and PCT application. To do that, I need the three cornerstone pieces of the submission produced to professional, examiner-ready quality: • Patent Claims – drafted to capture the inventive features and provide layered fallback positions. • Patent Description – a clear, enabling specification that aligns perfectly with the claims. • Patent Drawings – line-art illustrations prepared in strict accord with USPTO 37 CFR 1.84 so every figure number, margin, and line weight meets formal requirements. The concept is already sketched out, so you will start with my notes, preliminary sketches, and functional objectives, then refine them into a cohesive set of documents...

I’m upgrading a vehicle with a roof-mounted thermal imaging camera and need a streamlined enclosure that behaves a bit like a transformer: it must rise, give the camera a full 180° pan and at least 30° of tilt, then fold back and disappear under a low-drag cover when not in use. The core of the job is mechanical design. I’m after a concept that can be built either by 3-D printing or injection-moulding, so please keep draft angles, wall thickness and other DFM considerations in mind from the outset. Weather sealing, vibration resistance and smooth airflow over the stowed housing are essential, but I’m flexible on the exact material as long as it can survive sun, rain and highway wind speeds. I need sourcing motors, sensors, circuitry, the enclosure geometry...

Requirements: - Experience with concrete work - Understanding of load-bearing requirements - Ability to work with clay ground conditions

My electric garage door, operated by a handheld remote, has suddenly stopped moving in either direction. I have already ruled out dead batteries in the remote, so the fault sits somewhere in the opener, safety sensors, wiring, or motor assembly. I need a technician who can: • Diagnose why the opener is unresponsive • Repair or replace the faulty component (limit switches, travel module, gear kit, safety eyes, etc.) • Test the door for smooth, balanced travel and reliable remote operation afterward Please bring the tools and common replacement parts you normally use for electric garage door systems; brand-agnostic expertise is fine as long as you can source compatible parts the same day. Once the unit is working again, a brief hand-off showing me how to reset limits or ...

I need a detailed CNC-ready design for a small metal disc that will act as a machine part inside one of our assemblies. The core requirement is precision: the profile, hole pattern, and thickness all have to meet tight tolerances so the disc drops straight into an existing housing with no post-machining tweaks. Here is what I am expecting from you: • A fully dimensioned 3D CAD model (STEP or IGES) • Manufacturing drawings with critical tolerances called out • CAM data or G-code that can run on a standard 3-axis mill or lathe Material, cutter, and setup suggestions are welcome as long as they support repeatable accuracy. Surface finish is less important than getting the dimensions perfect, but feel free to recommend tweaks that could improve both if it doesn’t ...

I own a set of industrial-grade fans and want a clear picture of their current condition as quickly as possible. The job centres on a single spectrum vibration analysis that will reveal any bearing, alignment or balance issues.

Deliverables I need from you: • One FFT spectrum analysis file (raw and processed) • A written health report explaining detected faults, severity and recommended fixes • A template or brief guide for monthly condition-monitoring reviews I can perform myself You are free to use the vibration tools you prefer (e.g., VibXpert, Emerson CSI, SKF Microlog, MATLAB) as long as your output is compatible with common formats such as CSV...

Pracuję nad kilkoma koncepcjami nowych produktów i potrzebuję solidnych modeli 3D w SketchUp, które posłużą bezpośrednio do pierwszego etapu prototypowania. Interesują mnie przede wszystkim bryły mechaniczne – zależy mi na poprawnej geometrii, zachowaniu wymiarów oraz na czystej strukturze warstw, tak aby pliki mogły być później łatwo wyeksportowane do formatu produkcyjnego (STEP / STL). Preferuję natywne pliki .skp, ale jeżeli tworzysz w CAD lub CATIA, wystarczy – pod warunkiem, że dostarczysz równoległą wersję kompatybilną z SketchUp. Każdy model powinien odzwierciedlać rzeczywiste tolerancje i punkty montażowe; nie zależy mi natomiast na teksturach ani renderach wizualnych, liczy się poprawność bryły. Proszę o: • kompletny plik źr&oa...

I have built several tractor-mounted boom extensions and now I want solid, engineer-backed numbers on exactly how much weight each point along the boom can safely handle. The boom is welded from a 3/8" side-steer plate and a 2-1/2" × 2-1/2" × 3/16" square tube. From the plate it runs straight for 10 ft, then kicks up at a 30° angle and continues another 2 ft, giving a total length of 11 ft 10 in. Its primary job is lifting pole-barn trusses, so the working load will sit in the 500–1,000 lb range. I don’t have to satisfy OSHA, ISO, or any other formal standard, but I do want a clear, defensible safety factor. What I need from you is a straightforward structural analysis—hand calculations, FEA, or a mix—that tells me: • Ma...

I need a robust arc-suppression circuit engineered specifically for my RF welding machine. The goal is simple and non-negotiable: stop destructive arcing before it reaches the generator or matching network, protecting the entire system from costly downtime and repairs. Key points you should know up front • Purpose: prevention of equipment damage only—operator safety circuits are handled elsewhere. • Architecture: solid-state components throughout; no relays or mechanical contacts. • Ratings: I will share the operating voltage and current range once we start, so your design must be adaptable within those limits. What I expect to receive 1. Schematic with clearly labeled protection stages (detection, quench, reset). 2. Bill of materials with manufacturer p...

I need an experienced Amada laser programmer who can quickly turn my part drawings into production-ready code for cutting metal in the ¼"–½" range. All work is for steel and stainless only—no plastics or wood—so your settings, pierce routines, and kerf offsets must reflect that. Parts arrive as DXF/SolidWorks files and are already dimension-checked; what I’m missing is the clean, efficiently nested NC program that will let my operators load it straight onto the machine and start cutting. I’m on a tight timeline and would like the first set of programs ASAP, ideally within the next day or two, with a short feedback loop for any tweaks. Deliverables • Amada-compatible NC code (M/N files) for each part number • Nest layouts...

I hold a recently granted U.S. patent for a next-generation noise-abatement system for internal-combustion engines and now need a thorough, simulation-driven validation of its performance.

For an upcoming marine‐grade manhole cover fabrication for a drilling rig, I need a formal Welding Procedure Specification that meets every clause of AWS D1.1. Manhole covers will be assembled and inspected in a shipyard environment, so clarity, practicality, and code compliance are equally important. The finished WPS must: • Reference AWS D1.1 throughout and spell out all essential, supplementary and non-essential variables. • Be tailored to marine-grade carbon steel; include pre-heat, inter-pass, post-weld and any corrosion-protection notes unique to salt-water service. • Specify filler metals, shielding gases and joint preparations suitable for both yard and onboard repairs. • Come with a Procedure Qualification Record template (or existing PQR data if you...

I have a conical rainhead to fabricate in stainless steel with a base diameter larger than 20 inches. Before any cutting begins on the workshop’s CNC plasma, I need a clean, ready-to-cut flat pattern that unfolds the cone accurately, includes all seam allowances, and clearly marks bend lines, notches, and any overlap for TIG welding. Send me: • A fully dimensioned 2D pattern in DWG or DXF • A PDF print for quick shop reference • A short note on the development method you used (SolidWorks sheet-metal feature, AutoCAD, Inventor, etc.) so my team can reproduce it later if we tweak the angles. Tolerance target is ±0.5 mm along critical edges; please keep that in mind when laying out arcs and stretch-outs. If you have produced flat patterns for large-diameter ...

I have a steel storage box fitted with two lightweight, self-closing doors—one on the front and one on the top. The current hinges sit on the outside of the cabinet, and they spoil the overall look. I want to keep the same self-closing performance but move the hinge mechanism inside the enclosure and do it in a cost-effective way. Here is what I need from you: • Study the existing setup and door geometry. • Propose at least one practical internal hinge concept that can handle doors of up to 5 kg without sacrificing the automatic return action. • Provide basic CAD drawings or sketches with dimensions, material callouts, and mounting details so my fabricator can implement the change. • List any off-the-shelf components required (torsion springs, concealed h...

I'm looking for a comprehensive HVO (Hydrotreated Vegetable Oil) process design from start to finish. The project should include: - Full plant design - Costing estimates Design should encompass: - Architectural design - Mechanical systems - Machinery specifications - Full process specifications Ideal candidates should have experience in chemical process design, plant layout, and a strong understanding of HVO production.

I have a set of mechanical-ventilation drawings that call for rectangular ductwork in 20-gauge galvanized steel. I need a meticulous quantity survey and cost estimate that I can hand straight to our fabricators and, ultimately, to the client as a firm quotation. Your task is to extract every length, fitting, transition and accessory from the plans, calculate sheet-metal areas and weights, apply labour factors, and produce a clear pricing workbook. I expect the file in Excel (or a comparable format) with sections for raw material, fabrication hours, installation hours, consumables and mark-ups so I can adjust numbers if needed before submitting the quote. Accuracy is critical; the totals must reconcile with the drawings and the gauge specified. If you normally use tools like AutoCAD, Revi...

I already have a set of layout drawings that mark out where the eleven axial fans should sit across the 37 m × 27 m footprint of Basement 1 and Basement 2. What I need now is your help turning those mark-ups into a fully detailed, code-compliant smoke–extraction package. The core of the assignment is straightforward: confirm the proposed fan positions, size the very small amount of ductwork those fans will connect to, and show all dimensions, offsets and clearances so the installer can fabricate and fix without coming back with questions. Because the space is tight, I prefer the duct dimensions to stay flexible—use whatever cross-section best fits each run once you have checked airflow and velocity, as long as you remain within standard sheet-metal sizes. You will recei...

I have a PET bottle concept design. The right image shows the desired final look with advanced smooth surfacing and twist features. I need an expert in advanced surface modeling to convert the curve-based design into a smooth, production-ready PET bottle parasolid model.

I have an initial CAD model for a biomechanical hoof-protection shoe and now need it refined for real-world 3D-printed prototyping. The single most important improvement is a heel expansion flex zone that delivers a controlled 2–4 mm of movement under load. This flex feature must run across both heels and taper slightly toward the frog so the hoof can widen naturally without compromising strength on rocky ground. Beyond that critical zone, I also want you to: refine the frog relief, introduce a smooth toe rocker for easier break-over, carve a subtle concave sole contour, and generally lighten and reinforce the structure so it survives repeated impact when printed in TPU or flexible nylon. The updated geometry has to remain friendly to FDM or SLS printing, with clean overhangs and ra...

I have a consumer-goods concept that has already taken shape in my sketches, and now I need it translated into precise 2D drawings in SolidWorks. The goal is to secure clean, production-ready documentation that a manufacturer can reference without guesswork. Here’s what I expect: • Detailed orthographic views with accurate dimensions, tolerances, and annotations • Proper layer management, line weights, and title blocks that follow standard drafting conventions • Source files in native SolidWorks format plus exported PDFs for quick sharing Because this phase is strictly 2D drafting for product design, no simulation or 3D modeling is required—just crisp, fabrication-ready sheets that capture every feature of the part. If you are fluent in SolidWorks dra...

I need an experienced CAE specialist to help me finish my final-year mechanical engineering project: a fully detailed finite-element model of a small-caliber projectile striking a multilayer bullet-resistant vest. I have already defined the basic geometry and material stack-up in HyperMesh, and the plan is to solve everything with the explicit OpenRadioss solver. What I still require is expert guidance—and hands-on modelling work—so that the simulation reliably predicts: • penetration depth and overall armor performance, • the complete stress and strain fields inside the ceramic and composite layers (stress distribution, strain distribution), • projectile behaviour such as velocity reduction, deformation, and residual velocity, • correct energy accou...

I need to run a series of on-site load tests on several fixed posts installed in a confined area. Space restrictions mean the whole setup must rely on a compact, portable hydraulic arrangement rather than large jack systems or heavy rigs. The main goal is to confirm and fine-tune the posts’ performance under their design loads—this is strictly about performance optimization, not a one-time safety check. All procedures, calculations, and reporting have to align with the relevant international building standards, so any methodology you propose should reference the specific clauses you intend to follow. I will supply drawings, design loads, and access details once we start; you will handle everything from test plan to final report. Deliverables • A concise test plan showi...

3D CAD Design for Automated Gold Melting & Pouring Machine Project Description: I am developing a concept for an automated gold melting and pouring machine intended for jewellery workshops and showrooms. Currently, gold melting is performed manually using crucibles handled with tongs at temperatures above 1000°C, which can be unsafe and inefficient. The goal of this project is to design a professional 3D CAD model of a compact machine that safely melts gold and allows controlled pouring into a mold without manual handling of the crucible. Key Functional Concept: • A compact furnace chamber that holds a crucible for melting gold • A motorized tilting mechanism that can rotate the crucible holder to pour molten gold into a mold • A sturdy base frame for stability &bull...

I’m building a free-standing kinetic installation that tells a historical story through moving mechanical elements rather than costumed characters or electronics-heavy animatronics. The prop will rely on gears, cams, counterweights, and simple motor drives to create repeated, reliable motion sequences that feel period-authentic while still meeting modern safety standards. Here’s what I need from you: • Concept development that blends accurate historical styling with eye-catching, repeatable movement. • Mechanical schematics or CAD models (SolidWorks, Fusion 360, or comparable) showing linkages, drive systems, and fastener choices. • A concise bill of materials noting readily available components and period-appropriate finishes. • Assembly guidance and, if ...
