Team Vision for System-Level Design Phase
- The team planned to complete a functional
- From the functional decomposition we were able to
create a morphological chart.
- Using the morphological chart several concepts for a
potential motor control system were created.
- These concepts were then sketched to give us an idea
of what we would physically be looking at.
- Using the concepts feasibility questions were raised
by the team to ask critical questions of what we were
going to do.
- Combining the above we were able to create and
populate a Pugh Chart to decide which concept fit our
- We also used material from last review (engineering
requirements) and mapped them to different structures of
the functional decomposition.
- All of the above was accomplished during this phase.
Our Functional Decomposition diagram shows the
breakdown of function that the motor controller should
perform. The driving question for the entire diagram from
the top down is "how?", where the answer to that comes from
the box(es) below. Conversely when read from the bottom up
the question of "why?" is answered from the box above. Many
of the boxes come from the engineering requirements.
Avoid redundant work by identifying already available
solutions and concept options. Furthermore, to determine
what the market has to offer versus what we currently have.
Benchmarking of Different MCUs
Generate new concept options or combinations that can
potentially exceed the benchmark concepts. Furthermore, the
concepts can be subjectively worse than the current
configuration, but improved in cost, or some other aspect.
In general we aimed to improve upon the build of the
default controller (what is currently mounted).
Various Ideas for Concepts
Initial Concepts 1, 2 , 3
Concepts 1,2, and 3
The purpose of the morphological chart is to use the
functional decomposition chart to develop different ideas
and concepts of what *could* make up our final design. What
flows together, what doesn't, just get the creative
thoughts flowing. The ideas presented should fit the
customer and engineering requirements but does so by using
a variety of components.

Plans for next phase
By next review we hope to be building the supporting
circuit and programming the MCU so that we can begin doing
simple simulations and mock ups. By doing this we allow
ourselves ample time to make adjustments (Fail soft and
