机械设计 Jobs

I need detailed SolidWorks models of an aluminum framework that will ultimately serve a structural purpose. The concept is already sketched; what’s missing are precise, fully-defined 3D parts and an assembly that reflect real-world aluminum profiles, connection plates, and fasteners so I can run structural checks and move straight into fabrication. Please build the model parametrically so I can adjust profile sizes and overall dimensions without rebuilding everything. Standard aluminum extrusion libraries are fine if they speed things up, but custom profiles must match the dimensions I supply. Corner joints, gussets, and any load-bearing features have to be modelled exactly as they would be machined or welded. Deliverables • Native SolidWorks part and assembly files •...

I am developing a new spectacle frame and need a product designer who can balance engineering accuracy with eye-catching style. Both the mechanical function and the overall look carry equal weight for this project, so I’m counting on you to finesse every detail—from hinge geometry to surface curves—until the piece is production-ready and commercially appealing.

I need a production-ready robotic welding arm built in Blender that I can drop straight into an industrial-simulation scene for unreal engine . The model should sit in the “moderate detail” sweet spot: clean, believable geometry with sensible poly counts, visible joints, cabling and a realistic torch head, but without the ultra-fine nuts-and-bolts treatment that would bloat file size. Please rig the arm so every axis of motion is functional—base rotation, shoulder, elbow, wrist, and torch swivel—and then create a short, looping cycle that shows a full weld sequence: move into position, strike arc, trace a seam, retract, and reset. All pivots have to align with real-world kinematics so the animation can be retimed later without drifting. PBR materials matter becaus...

I have developed the functional concept for a professional-grade handheld spray tool that will be used every day in demanding field conditions. The form factor and ergonomics are largely defined; what I now need is a SolidWorks specialist who can translate my sketches and specifications into a fully detailed 3D model ready for prototyping. The core of the job is mechanical: an assembly of metal parts—primarily aluminium and steel—with a robust threaded connection system that can be produced on standard CNC and turning equipment. I will provide a comprehensive brief covering dimensions, performance targets, and load cases as soon as we have an NDA in place. You will retain the flexibility to optimise wall thicknesses, tolerances and fastening choices, and I am open to your reco...

What the project is A comparative structural impact study of three lightweight occupant-cell concepts for a small side by side 2 seater urban vehicle: 1. Tubular frame (aluminium) 2. Monocoque frame (preferably carbon or maybe polyurethane like foam filled stuff) 3. Hybrid redesign based on the weaknesses found in 1 and 2 The occupants are side-by-side in every case. The impact speed is 28 mph (45 km/h) in every case. The impact conditions are: • frontal impact • side impact The purpose is to find which concept gives the best occupant protection for a lightweight design.

I’m working on the next-generation gear systems that will drive our CNC turning centres, vertical machining centres, and multi-axis machines. What I need right now is a fresh, precise mechanical design for those individual gear components—everything from tooth profile definition through tolerance-ready manufacturing drawings. Here’s what the collaboration looks like: • Scope ‑ Purely mechanical design: no electronics or control work this round. ‑ Component-level focus: shafts, pinions, spur/helical gears and their mating relations inside the gearbox. ‑ The design must integrate smoothly with our existing machine envelopes and lubrication layouts at JYOTI CNC Automation Ltd. • Typical workflow 1. You receive my baseline requirements, speed/torq...

We have a electronic siren system which have some electronic components. There is a metal enclosure in which all the components are placed. The problem is that, the current system is temporary like a jugaad. We want to get the modular system designed so the goal is: 1. make every component plug and play 2. wirings and cables hidden inside and secure 3. make connections plug and play 4. Thermal dissipation so system cools down internally as there is no exit in the enclosure 5. make system compact and robust for coastal and extreme conditions. 6. Heat sinks and other ways we can make it temperature controlled. Let me also attach a basic requirements document also (AI generated according to our requirements) You are an expert so you can also suggest the implementation things.

I have a consumer-oriented packing concept that feeds items into plastic sleeves, heat-seals them, and advances to the next cycle. The core idea is solid and I need detailed drawings, and the mechanics. I now need these drawings converted into a fully engineered, test-ready design. Your task is to transform the concept into a complete 3D CAD assembly, flesh out every moving part, and specify the materials that will survive repeated heat, friction and load. I want to see how the film advances, where the sealing jaws sit, how the drive train engages and resets—every cam, gear or actuator modelled so we can simulate the full feed-seal-cut sequence before metal is cut. Deliverables • Parametric 3D model of the entire mechanism (SolidWorks, Fusion 360 or comparable) • Detail...

The client is seeking a product design solution for a physical 5x5 tile slider (24-tile puzzle) with a key functional enhancement: the ability to remove and replace individual tiles. The initial focus is strictly on modifying an existing base design to allow for tile removal while maintaining the usability of a standard sliding puzzle. Additionally, the client is interested in exploring the feasibility of producing an electronic version with similar functionality once the mechanical system has been proven. Materials for the product can be either plastic or metal, depending on feasibility and cost-efficiency. A major priority is minimizing tooling and production costs, with a preference for leveraging or adapting an existing UK-based manufacturer capable of modifying current designs. ...

Project Overview We are developing a compact cylindrical chamber where fluid enters tangentially to create a strong vortex flow. The chamber currently produces rotational circulation, but we want to enhance the swirl strength and stability. The goal of this project is to design internal helical guide ribs (swirl-inducing surfaces) along the inner wall of the chamber to improve fluid circulation and increase angular momentum in the vortex core. We are seeking an engineer with experience in fluid mechanics and mechanical design to optimize the internal rib geometry. System Description Chamber type: cylindrical vortex chamber Internal diameter: ~150 mm Chamber height: ~200 mm Material: PVC or similar plastic Fluid: water Flow type: tangential inlet jets generating vortex circulation ...

I’m building a compact, four-legged robot and need a mechanical designer who can take it from concept to validated CAD. Whether you prefer SolidWorks or Fusion 360 is completely up to you—the important part is a solid background in robotics mechanisms, joints, linkages, and gears, backed by a portfolio that shows assemblies in motion rather than static renders. Project scope The core task is a lightweight yet strong leg architecture. Each leg will have hip and knee joints that must offer a wide range of motion and allow precise control once the actuators and gearing are in place. Please reserve internal volume and mounting points for a Jetson board alongside a battery pack, and route cabling logically so the final build stays neat. What I expect from you • A full 3D ...

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG. Once the PIG is in service, the beacon’s field must be strong enough to be detected up 3–5 m above the pipe, even when the signal has to pass through steel wall, backfill, soil, and asphalt or reinforced concrete. All operations take place underground and fully enclosed by steel, so coil geometry, core selection, drive strategy, and noise rejection are critical. Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry fo...
