Design and Build Exercise - Take 2
Thursday March 25
Design
The task of each team is to design a free standing frame made
of newspaper, in which the entire team can stand upright together.
The frame must enclose the team on all sides as well as above. It
does not need to have a floor or walls. The team must be able to
enter and exit the intact structure.
Each team will be allocated 8 (eight) full-sized sheets of
newspaper per team member, plus 10" of masking tape per team
member.
After 20 minutes, each team must turn in their construction
drawings and instructions for their structure. The drawings, plus the
unused newspaper and masking tape, must be sufficient to construct the
structure as designed. All newspaper that has been used to construct
prototypes, which cannot be returned to its original folded state,
will be recycled immediately.
The construction team will not have rulers, calculators, etc.
You can assume that they will have a pen or a pencil.
Build
The task of each team is to build the free standing structure
designed by another team using their instructions, their remaining
newspaper and their remaining tape. You have 30 minutes maximum to
build the structure.
You may not talk to anyone who is not on your team.
Scoring
Design Team Points
- Design requirements. All of the members of the design team
can stand upright in the structure together. Maximum 25 points. 5
points off for each team member who doesn't fit. 1 point off for each
protruding head, arm, or leg.
- Minimal use of materials. Points awarded in rank order of
material use. Maximum 10 points.
Construction Team Points
- Adherence to design intent (i.e. to the drawings and
instructions). Maximum 15 points.
- Improvements to the design. Improvement must be documented and
must increase the design team's score. Maximum 10 point bonus.
Points shared by Design and Construction Teams.*
- Structural integrity, measured by deflection under a gentle push.
(Remember that structures have zero degrees of freedom!) Maximum 15
points.
- Build time. Points awarded in rank order of
construction time. Maximum 5 points.
- Aesthetics. Maximum 7 points.
*For any particular structure, each team gets half the points for this
category. So some of your points for this category will come from the
structure you designed and some from the structure you built.
