Purpose of class
This course is a hands-on engineering design practice focusing on the analysis, redesign, and fabrication of everyday products. Students select an existing product from their daily lives, analyze its function, structure, usability, and manufacturing method, and propose an improved design.

Using 3D CAD and 3D printers as core tools—optionally supported by 3D scanning and numerical simulation—students experience the complete engineering design cycle:
design → prototyping → evaluation → redesign.
Course description
Each student works individually (or with limited collaboration as appropriate) and completes the course by submitting a fabricated prototype and an A4 two-page technical report, which together form the basis of evaluation.
Goals and objectives
  1. Analyze everyday products from an engineering perspective
  2. Identify design problems and translate them into design requirements
  3. Design product geometry and structure using 3D CAD tools
  4. Fabricate prototypes using a 3D printer and evaluate their performance
  5. Improve designs based on testing and evaluation results
  6. Clearly document design intent, manufacturing methods, and evaluation outcomes in a technical report
