  2. 2. Contents IO2081 Modelling • Modelling & Product Design • Insights • Content Brief • Reflections • Upcoming in Thursday Challenge the future 2
  3. 3. The design process is fraught with questions Which wall thickness? Which material? Who will use it? How will it be used? … Hot or cold water? Challenge the future 3
  4. 4. We think Alberto Alessi Challenge the future 4
  5. 5. We use abstract models to ‘touch’ our thought like this sketched man? no, the man is not an abstract model this is da Vinci’s abstracted model (language: Eucledian calculus) Challenge the future 5
  6. 6. We experiment to verify both our thoughts and models Challenge the future 6
  7. 7. What are their relations ? Model Experiment Relations? Thought Design Challenge the future 7

  9. 9. One thing to keep in mind... Your mind thinks without you ...which is a very fortunate thing, as we shall see! (still, it’s up to you to check if it’s on track) Challenge the future 9
  10. 10. A look under the hood: Modelling in design what are you studying? Case brief ‘touch’ your thoughts choices what exactly...? System choices what do you foresee? what does your model foresee? choices Thought simulation Experience Build abstract model choices Solve / simulate Compare everything you did/ saw/ felt/ remember to be true... Finish! did you both agree? Acceptable ? Revisit choices do you need more insights/ data? Experiment Challenge the future 10
  11. 11. Cause & effect – The key to modelling Challenge the future 11
  12. 12. Cause & effect – The key to modelling Cause Cup falls off a table, hits the floor Identify What is special about falling off a table? Long distance, high speed, high acceleration at impact? etc cause-effect relationship Understand cause-effect relationship Quantify cause-effect relationship Effect ‘It is not the fall that kills you, but the sudden stop at the end’... Acceleration causes large forces... Accelerations during impact The cup is damaged Challenge the future 12
  13. 13. Cause & effect – The key to modelling Cause Identify You fill a cup with hot coffee What is special about filling a cup with coffee? cause-effect relationship High temperature, spilling, heat transfer? etc Understan d Heat migrates across temperature gradients (temperature difference), until steady state cause-effect relationship Quantify cause-effect relationship Effect Surface temperature rise with time You burn your fingers Challenge the future 13
