      Iterate with modelling: saving space

      Lesson details

      Learning outcome

      I can iterate ideas for a piece of student furniture using card, foam and other materials.

      Key learning points

      1. Designers iterate as a direct result of testing, analysis and evaluation of a physical prototype.
      2. Design iterations consider user needs and wants, this can be empathetic or direct feedback.
      3. Analysis and evaluation can be carried out on design ideas to aid iterations.
      4. By using the evaluation points, the designer can make informed decisions.
      5. Design decisions lead to effective improvements that meet the needs and wants of the user.

      Keywords

      • Developing - improving and building on design ideas to make them better

      • Iteration - process of refining and improving a design

      • Analyse - to examine something in detail

      • Evaluate - to think about what you did and suggest any changes or improvements

      Common misconception

      Iterations of models are purely based on the thoughts of the designer.

      Iterations can be based off a range of analysis and evaluations such as evaluating against the users needs and wants as well as direct feedback from the user.

      Teacher tip

      Previous model/s made by the students will be needed.

      Equipment

      Models and modelling materials and tools such as white card, corrugated card, balsa wood, felt, split pins, masking tape, foam, knives, cutting mats, glue guns, needle and thread etc.

      Correct Answer: sketching, initial design ideas, designing

      Q2.
      Which of these are benefits of sketching?

      it eliminates the need for feedback from a client
      Correct answer: it avoids money being spent on prototypes before working the idea out
      Correct answer: it allows for quick idea exploration and visualisation
      it allows for the best idea to be drawn straight away
      Correct answer: it encourages creativity without the designer being limited

      Q3.
      The ability to store things in a piece of furniture would be described as its ...

      ergonomics
      Correct answer: function
      aesthetics
      cost

      Q4.
      What can 3D modelling show about your design that’s harder to understand from a sketch?

      Correct answer: proportion
      cost
      colour
      Correct answer: scale

      Q5.
      Why is corrugated card useful for 3D modelling?

      Correct answer: low in cost
      waterproof
      Correct answer: sustainable
      high-quality finish
      Correct answer: relatively strong

      Q6.
      What is the name of this timber that is great for modelling?

      An image in a quiz
      Correct Answer: MDF, medium density fibreboard

      4 Questions

      Q1.
      The process of refining and improving a design is called?

      Correct Answer: iteration, development

      Q2.
      Why is it important to iterate design ideas?

      because original ideas are always perfect
      because repeating the same design saves time
      Correct answer: because they can usually be improved

      Q3.
      When we examine something in detail we ...

      Correct answer: analyse it.
      simplify it.
      memorise it.
      overcomplicate it.

      Q4.
      Put these parts of the design process into order.

      1 - design
      2 - analyse
      3 - evaluate
      4 - iterate
