    Lecture Slides: Lecture Introduction to Modelling Lecture Slides: Lecture Introduction to Modelling Presentation Transcript

    • G-I-1 Introduction Modelling is the way of thinking Dr. Y. Song (Wolf) Faculty of Industrial Design Engineering Delft University of Technology Challenge the future 1
    • Contents IO2081 Modelling • Modelling & Product Design • Insights • Content Brief • Reflections • Upcoming in Thursday Challenge the future 2
    • 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
    • We think Alberto Alessi Challenge the future 4
    • 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
    • We experiment to verify both our thoughts and models Challenge the future 6
    • What are their relations ? Model Experiment Relations? Thought Design Challenge the future 7
    • Insights Challenge the future 8
    • 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
    • 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
    • Cause & effect – The key to modelling Challenge the future 11
    • 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
    • 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
    • Modelling-simulation-design We do need a handle! Challenge the future 14
    • Modelling: The basic loop Identify, choose Learn Evaluate Model Solve/Simulate Challenge the future 15 Courtesy of http://crapo.senate.gov/services/ConstituentCoffee.cfm

    • Modelling: The basic loop Identify, choose Learn Learn Evaluate Model Solve/Simulate Challenge the future 20
    • Modelling: The basic loop Identify, choose Learn Evaluate Model Solve/Simulate Challenge the future 21
    • Content brief Challenge the future 22
    • Case studies: Accessible knowledge with a vision 2012 ~ 2013 Advanced Embodiment Design (Many projects cover several disciplines) Statics 27% Dynamics 41% Biomechanics 55% Thermo 27% Fluid 41% Anthropometr y 0% 77% 20% 40% 60% 80% 100% Challenge the future 23
    • The scope of Modelling … … Case studies: Product modelling Mechanics Biomechanics Case studies: Human body modelling Anthropometric model Thermodynamics Fluid mechanics Anatomy Mathematics Social-technical-economic-environmental context Challenge the future 24
    • Case studies: Accessible knowledge with a vision Truth 98% accurate Challenge the future 25
    • Reflections Challenge the future 26
    • We say that curiosity is fun knowledge is power science is easy computers experience can be harnessed are tools hard work is the way to success modelling is the way to wisdom Challenge the future 27
    • Upcoming on Thursday Challenge the future 28
    • On April 25, 2013, we will design: Challenge the future 29
    • Questions! Challenge the future 30
    • What did you learn today? knowledge is power knowledge hard work is for geeks is for the uninspired hard work is the way to success Challenge the future 31
    • What did you learn today? we need handles on coffee cups, the first reason is... they keep us from burning our fingers they look nice Challenge the future 32
    • What did you learn today? model cause- effect relationships to design a successful product we need to... try a lot of experiments Identify, choose Learn Evaluate Model Solve/Simulate Challenge the future 33
    • G-I-1 Succes Modelling is the way of thinking Prof. Dr. Christos Spitas Dr. Y. Song (Wolf) Faculty of Industrial Design Engineering Delft University of Technology Challenge the future 34
