1. IC283 Prototyping for Form Exploration Subject Overview

2. http://tds.ic.polyu.edu.hk/digital_design/site_ic283_prototyping/

3. What is IC283 About Develop a good looking, CAD reproducible form by hand Forms with constrains Styrofoam, grey foam, acrylic, polystyrene From ‘ruler-class’ to ‘calliper-class’ accuracy Human factors related to product form Proportion, contrast, balance, harmony, etc.

4. What is IC283 NOT About Develop a good looking form entirely in CAD Boundless artistic freedom or disciplined engineering rationality Clay, wood, cloths, wire, etc. ‘Naked-eye-class’ or ‘engineer-class’ accuracy Human factors related to product operation Strength, elongation, hardness, etc.

5. Learning Outcomes OC1: Plan and execute physical modelling process to explore and improve the aesthetic quality of the product being designed OC2: Build neat and sturdy sketch models suitable for communication and presentation OC3: Document form exploration process and results using technical and visual vocabularies, allowing others to reconstruct or modify the form by CAD without loosing the design intent OC4: Demonstrate sensitivity to visual elements and reflective visual skills relevant to future learning OC5: Articulate plastic representation of ideas and generate critical discourses in related topics OC6: Have developed an attitude to constantly evaluate practices and trends in the field

6. Aligning Our Goal

8. Overall Framework Part 1  Week 1 - 5  Get used to form exploration by sketching and model-making interactively  Assignment: A short sketch modelling exercise Part 2a  Week 6 - 9  More precise surface sculpting and aesthetic judgement  Assignment: Solid rigid-foam model of good aesthetic quality Part 2b  Week 10 - 14  Prototyping skills useful for presentation and later studies.

9. Assignments One assignment per module plus design journal Module 1: A short sketch modelling exercise Module 2: Solid rigid-foam model of good aesthetic quality Module 3: Step-by-step fabrication of a hollow plastic casing

12. Subject Reflection Most students appreciate the subject Know more about prototyping and better forecast Be able to apply only some techniques in projects Prototyping techniques from different sources are confusing if not contradictory The heavy workload at the end of semester interferes assignment 3, making the assignment a burden rather than a learning process The more to teach, the less to master

13. Subject Ground Rules Wear safety shoes and protective clothes Always have your set of tools and stationary around Appreciate the work-flow and attitude by following the demonstration Work safely and prudently Save material Keep your workplace tidy, and clean up before you leave Plagiarism and vandalism will result in subject fail
