Engineering Design Process

  • Systematic approach to creating and refining solutions to engineering problems
  • Begins with identifying and defining the problem or need
  • Conduct research to gather information and constraints related to the problem
  • Generate multiple concepts and ideas through brainstorming and ideation techniques
  • Evaluate and select the most promising concept based on criteria (functionality, feasibility, cost, etc.)
  • Create detailed designs, specifications, and models of the chosen concept
    • Use computer-aided design (CAD) software for 3D modeling and simulation
  • Build and test prototypes to validate the design and identify areas for improvement
  • Refine the design based on testing results and feedback from stakeholders
  • Implement the final design, ensuring proper manufacturing, assembly, and quality control

Tools and Technologies

  • Computer-aided design (CAD) software (AutoCAD, SolidWorks) for creating digital models and drawings
  • Finite element analysis (FEA) tools for simulating and analyzing stress, strain, and deformation in structures
  • Computational fluid dynamics (CFD) software for modeling fluid flow and heat transfer
  • Programming languages (Python, MATLAB) for data analysis, automation, and numerical computations
  • Rapid prototyping technologies (3D printing, CNC machining) for creating physical models and prototypes
