design exercise ii
Design Exercise II
  • Each team should create a design for a bridge using a single set of Geomag magnetic sticks and balls.
  • The bridge must span an 8 inch gap.
  • The bridge must be able to suspend a large can of Play-Doh at an arbitrary spot on the bridge.
  • The cost of the bridge should be minimized. Each stick and each ball cost 1000 dollars.
exercise ii cont d
Exercise II, cont’d.
  • On Tuesday, bring a description of your design to class.
  • This description must be text only. This is important. The description must be text only.
  • Another team will build the bridge according to this design, and will have 20 minutes to do so.
  • The design team and build team will not be able to communicate or clarify anything with each other.
  • The designers and builders of the lowest cost bridge that spans 8 inches and supports the can of Play-Doh will win.

Exercise II, cont’d.
  • Now it’s time to BUILD your bridge …
  • Again, NO communications between design team and build team !
  • … 20 minutes …
exercise ii cont d2
Exercise II, cont’d
  • The cost structure of sticks and balls has changed
    • blue and green sticks cost 2000 dollars
    • yellow sticks still cost 1000 dollars, but no ball can have more than one yellow stick attached to it
    • red sticks still cost 1000 dollars, but no ball can have any red sticks attached to it
    • for each ball that violates these restrictions, a 5000 dollar "reinforcement" penalty will be incurred
  • The build team will need to improvise to address this change
  • You have 10 extra minutes
reflection
Reflection
  • As a builder
    • was the design understandable?
    • was the design complete?
    • was the design modifiable?
    • how much did you have to deviate from the original design?
    • what do you think of text as the representation for the design you built?
    • did you feel you were designing?
reflection1
Reflection
  • As a designer:
    • what do you think of text as the representation for your design?
    • how much could you draw upon your existing knowledge of bridges?
    • how much did the limited amount of materials (e.g., number of sticks and balls) influence your design?
    • Designer: how did the caveat that “some things may change” influence your design and design process?
