Design Optimization Jobs

I need an experienced mechanical engineer to rethink an existing machine so it runs significantly more efficiently. The current design performs its task reliably, but power consumption is high and several moving components cause unnecessary downtime for maintenance. You will receive the original 3-D CAD model (SolidWorks) along with performance logs, vibration data, and photos of wear points. Your task is to analyse the weak spots, propose redesigns for critical sub-assemblies, and demonstrate—through calculation or simulation—that the new concept will cut energy use and extend component life. Key deliverables • Updated CAD files and 2-D manufacturing drawings in native and neutral formats • Brief engineering report detailing the design rationale, efficiency g...

Neo-Hookean is suitable as a starting hyperelastic material model for snap-through structure, especially if we are using a TPU/rubber-like material and the strain level is not extremely high. start with Neo-Hookean for the baseline ANSYS model because it is simple, stable, and easy to calibrate. Then, if my experimental TPU data shows large nonlinear deformation that Neo-Hookean cannot match well, compare it with Mooney–Rivlin or Ogden. For snap-through analysis, the important point is that the material model must handle large strain + large deformation. Neo-Hookean does this much better than a simple linear elastic model. but “A Neo-Hookean hyperelastic material model was initially selected to represent the nonlinear elastic behaviour of the TPU structure under large deform...

I already have a complete set of architectural drawings, but the interior layout no longer matches my needs. I want a skilled architect or designer to re-work the plan strictly from a design perspective—no structural moves—so the flow of the rooms is more efficient and contemporary. Scope I need to have new drawing done have old ones we need to add drawing of fire curtains That have been add under the sup floor Acceptance Revised drawings must align with local code clearances and keep existing load-bearing walls untouched. Once the 2D layout is approved, I may open a follow-up project for 3D visualization.

I need a licensed structural engineer who works comfortably in CYPECAD to take my low-rise commercial building (1–5 floors) from concept to fully checked, code-compliant design. Scope You will build the complete CYPECAD model, run all necessary static and dynamic checks, optimise the member sizes, and verify compliance with the governing codes for gravity and lateral loads. Once the model is locked, translate the results into clear construction drawings and a calculation report that another engineer can independently review without back-and-forth. Deliverables • CYPECAD project file with all libraries and load cases • PDF set of structural plans (foundation, framing, reinforcement, sections, schedules) ready for permit submission • Sealed calculation report cover...

I’m working on a new commercial fit-out and need complete interior design plans tailored specifically for a retail space. The shell of the unit is already defined; what I’m missing are polished, construction-ready drawings that translate our brand concept into an engaging customer journey from storefront to checkout. Here’s what I expect as final deliverables: • Dimensioned floor plan with furniture and fixture layout including drawings for mezannine floor • Reflected ceiling plan showing lighting strategy, ducting, Dx hvac, fire prevention, sprinklers • Two to three key elevations / sections highlighting merchandising wall • attaching a list of drawings required for approval from builder. Also attaching a rough layout plan for the store The store...

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 have a power-board inverter destined for a modern battery-electric vehicle and I need a complete thermal solution developed around it. The work starts with accurate 3-D modelling of the board, then moves into designing an aluminium heatsink that houses an internal liquid-coolant channel. Every design decision must be validated in ANSYS/COMSOL, as that is the simulation environment we use in-house. The study has three inseparable goals: maximise heat-dissipation efficiency, keep every critical component within its target temperature window, and optimise the coolant flow path so pressure drop stays reasonable. You are free to choose the most suitable ANSYS modules—Icepak, Fluent, Mechanical, or Workbench—as long as the final package covers both conjugate heat transfer and CFD....

I’m setting up a small but professional environment where I can run a legal-awareness program alongside my day-to-day legal practice. The space must feel credible to clients, comfortable for one-to-one consultations, and versatile enough to double as a classroom for workshops and talks. My priority is getting maximum impact on a tightly controlled budget, so every design choice—from layout to finishes—needs to balance cost with a polished, contemporary look that reflects the seriousness of legal work. Key focus The heart of the project is a class-conduct area that quickly converts from lecture seating to discussion pods without feeling like a makeshift solution. I’m open to hearing how a compact reception or storage wall might be woven in if it keeps the overa...
