### Design Exercises

Informatics 121

Oct 28, 2008

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.
• 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’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
• 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?
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?
