I have a working Fusion 360 model of a patented oscillating tool attachment. The existing Fusion 360 assembly was intentionally created to clearly communicate structure, function, and motion — primarily for patent and legal review. That objective has been met. The file needs a professional mechanical redesign and full DFM (Design for Manufacturability) refinement for prototype production. The assembly includes both polymer (injection-molded) and metal (CNC or stamped) components with a unique mounting interface. Proper wall thickness, draft angles, tolerances, and realistic fits are critical. You will receive my current Fusion files. Your task is to rebuild or refine the model so that: • All components are cleanly structured and clearly named • The design is fully paramet...
I need a hands-on field service engineer who holds an EPA 608 refrigeration certification and can spend most of the time keeping our food-processing equipment running at peak efficiency. The heart of the job is maintenance—specifically, accurate calibration and adjustment of temperature controls, pressure switches, flow meters, vacuum and any other critical components that keep product quality and safety within spec. You will also travel to customer sites to install new food-processing machinery. Once the hardware is in place you may have to work with PLCs, tweak ladder logic, and verify that every sensor and actuator reports correctly before sign-off. Although troubleshooting is part of life in the field, I measure success by how well the preventive work you do avoids unplanned dow...

Project Description: CFD–FSI Analysis of Flexible Flapping Wing Aerodynamics This project focuses on the numerical investigation of unsteady aerodynamics of a flapping wing with flexible deformation using coupled Fluid–Structure Interaction (FSI) simulations. The objective is to understand how wing flexibility and deformation affect vortex formation, wake evolution, pressure distribution, and aerodynamic force generation (lift and thrust). The study will be carried out using transient CFD coupled with structural deformation, where the wing undergoes prescribed flapping motion and deforms under aerodynamic loads. The interaction between fluid flow and structural response will be analyzed over multiple flapping cycles. Key Scope of Work Perform transient CFD simulations of a ...
I want to take traditional conveyor-belt tensioning a decisive step forward by creating a completely motorized, cable-and-pulley system that adjusts itself on the fly. The goal is to maintain optimal belt tension at all times—compensating automatically for stretch, wear and changing load—so downtime, manual checks and premature belt failures disappear. My vision centres on a robust mechanical layout married to intelligent control. Integrated real-time tension monitoring, wear-detection sensors and load-variation sensing will feed a compact controller that drives the motorised actuator. Wireless control and monitoring must let operators check status or initiate overrides from a tablet if needed, and the firmware should generate predictive-maintenance alerts long before an issue...
