Transmission LEGO Practice
In Chapter 2, the
matrix method” was introduced for comparing and evaluating different
design concepts. The following figures depict 3 different design concepts of the
lifting mechanism discussed in class.
In the following
two-hour practice session, two kinds of LEGO kits are provided, and each team
can pick one LEGO kit for practice.
Use your LEGO kit to
complete working prototypes of the 3 design concepts. Demonstrate each LEGO
mechanism to the TA. The TA has constructed examples of LEGO mechanisms. But
try to come up with your own prototype.
Based on the observation of
your LEGO prototypes, use the decision matrix method to compare the 3 design
concepts. Complete your evaluation at the back of this paper and turn it to the
Students who are
present in this session and complete this practice will get 2 bonus points. After
this practice, each team may keep your own LEGO kit and use your LEGO kit for
the following projects this semester. At the end of his semester, all the teams
should return your LEGO kits in good condition.
