1. Material selection: Research and recommend suitable materials based on strength, durability, and cost. 2. CAD generation: Create 3D models and technical drawings using CAD software (SolidWorks/AutoCAD/Creo). 3. Analysis: Perform simulations (FEA/CFD) to evaluate design performance under different conditions. 4. Prototype development: Assist in building and assembling prototypes for testing. 5. Testing & validation: Conduct mechanical tests, record data, and prepare performance reports. 6. Documentation: Maintain design records, test results, and improvement suggestions.
