Lead Mechanical & Functional Designer of Compact Moisture Purging System • Successfully designed & built 4 variants of moisture purging unit prototypes within a tight 2-month timeframe. Physical prototype units were featured in the UK defence technology exhibition show (DSEI 2021). • Made key decisions on assembly internal layouts, where ergonomic, functionality, ease of production & maintenance were factored in and justified. • Prepared precise 3D prototype assembly model in Autodesk Inventor to ensure faultless assembly. • Issued 2D fabrication drawings for CNC and sheet metal components with defined tolerance and finish. • Sourced & procured all required process instruments & mechanical components across multiple online based suppliers. • Conducted trial-fit assembly testing. Liaised with electronic engineer to conduct functionality tests. • Led regular progress meetings with managing director, lead electronic engineer and production technicians to present & generate creative ideas. Lead mechanical design engineer / consultant for existing & new proprietary products • Generate mechanical designs and CAD drawings for bespoke desiccators, humidity indicators & pressure relief valves in quick turnaround (produce 3-4 new designs per month). • Optimise & validate flow performance of relief valves and desiccator devices using Autodesk CFD package. • Perform mechanical, thermal & psychrometrical calculations using first principles & established evaluation methods. Ensure functional designs satisfy customer’s criteria. • Troubleshoot mechanical issues & amend out-dated proprietary designs and faulty components. • Lead the operation of Coordinate-Measuring Machine (CMM) to conduct manufacture tolerance analysis. • Mentor junior / intermediate engineers. Aiming to train them up to professional / chartership level. • Lead the operation of company’s FDM & SLA 3D printer for rapid prototypes. Troubleshoot 3D printer hardware & technical issues encountered by colleagues. Show less
