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 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. READ BELOW- DESIGN WILL BE OF 2 PARTS - 1 FRAME - THIS ALLOWS LENS TO BE LOCKED INTO IT WITH HANDS 2- LENS FRAME - USED TO FIX LENS IN IT AND THEN IT GOES INTO THE FRAME TO BE LOCKED. THERE NEEDS TO BE A SEMI PERMANENT LOCKING MECHANISM. Key design parameters • Material: the frame will be injection-moulded in PC or TR90. Every feature must respect the flow, draft and wall-thickness constraints typ...

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...

Project Title: Bio-Inspired Disc Brake Design with Dust Collection System (ANSYS Analysis) Project Description: I am a final-year engineering student working on a disc brake project.

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...

I need a detailed modal analysis carried out in ANSYS Mechanical (Workbench or APDL) on a composite beam that is mounted on linear springs at both ends. The study is part of my master’s research, so every modelling choice—from element selection and mesh sensitivity to boundary condition justification—must be fully traceable. Two configurations must be investigated: 1. The bare beam on linear springs. 2. The same beam on linear springs with a centrally-mounted lumped mass (a disc). I already have the exact beam dimensions and material properties for the composite lay-up; I will share them once the project starts.
