[HW4b]: Concept Generation NOTE: Submit online AND bring hardcopies to Section
Objective: To generate creative design solutions, it is best
to come up with a high number of concepts at the beginning of a design process
without worrying too much about feasibility. Afterwards one can narrow down and
select the concept to pursue. It is also essential to be able to communicate
the design concepts effectively. In this assignment each students will use
their sketching skills to communicate their ideas.
Each team member is to develop
4 design concepts for the contest. Each concept should be written up on a
separate page using hand sketches and clear comments. Concepts should be
completed BEFORE section, since you will use them in your first team exercise.
For each concept include:
- Name of Concept
- Hand Sketch of Concept (with annotations – name
parts on drawing).
- Use a complete plain 8.5”x11” piece of paper
for each sketch
- Check out sketch examples below by Ivana Lee and link to one be Robert Hughes.
- List Advantages and Disadvantages (include
ease of fabrication)
- List all possible failure modes you can think
off
- List highest risk issues in design
- Describe Possible Risk Reduction Tests for this concept
- Paper
clip (not stapled) all concepts
together so they can easily be separated and laid out in front of team.
- Also submit online!

What
is a Risk Reduction Test?
- The goal of a Risk Reduction Test is to use the
quickest possible way to determine if a design concept will work as
planned.
- It is ok to “cheat” in risk reduction tests; use
parts that are not in the kit or look on the web for performance of
similar concepts.
- Examples:
- Is there enough energy to make the concept work
- How much accuracy is required for the design to
work.
- Is there enough space for all the machine parts
to fit?
- Other …
