*BIODESIGN considers prototyping part of “analysis” or “concept selection”- Designers create 2+ prototypes, analyze them, and choose 1 to commercialize (implement). �In this course, we will select only 1 idea to prototype.�

•  Develop Need Statement ��•  Acquire and apply technical knowledge�

•  Identify resources necessary ($, time, personnel)�

•  Develop and prioritize qualitative design goals � /needs criteria�

•  Identify quantitative design specifications�

STEP 2: Problem Formulation / Needs Screening�

Creativity in Business Development: 3 components ��

"Facts: we are all good at fact finding - a result of our education system’s preoccupation with facts�

�"Ideas: play & exploration at the heart of finding new ideas��"�"Solutions: most engineers enjoy solving problems�

��

Each step deserves equal time !!! �

tendency to go directly from facts to solutions �

STEP 3: Brainstorming�

STEP 3: Brainstorming�•  Want to generate as many different design alternatives as possible�

-  1 medical need�-  6 knowledgeable participants�-  90 minutes �-  goal of 100 new ideas�

•  A good engineer never settles on his/her first idea��

•  Enabled by participants with diverse backgrounds, points of view, and expertise�

Rules for Brainstorming �1.  Defer judgment: accept even silly ideas�

2.  Encourage wild ideas: can stimulate creativity�

3.  Build on the ideas of others: “building on X’s idea, what if…”�

4.  Go for quantity: 50+ ideas in an hour�

5.  One conversation at a time: listening is as important as talking �

6.  Stay focused: record unrelated thoughts or questions to discuss later�

7.  Be visual: use whiteboard, flip pad, sticky notes, props, etc�

�

Appoint a facilitator to enforce the rules, prevent lingering on 1 idea too long, and move the group in fresh directions�

Scamper Method�Substitute: white board for chalk board��

Combine: spork ��

Adapt: road bike into mountain bike��

Modify: car into convertible��

Magnify: car into limo ��

Minify: laptop computer��

Put to other uses: futon is couch and bed��

Eliminate: cordless phone��

Rearrange: recycling machines�

Step 4: Analysis�•  Prioritize design goals�•  Assign weighting factor (WF= 1 to 100) to goals: �–  71-100 "Critical�–  31-70 "Important �–  0-30 "Optional�

�

Step 4: Analysis��

•  Score the design alternatives for their ability to meet each goal: �

"10 = Excellent �"8 = Good �"6 = Satisfactory �"4 = Mediocre �"2 = Unacceptable�"0 = Failure �

•  Combine this info in a decision matrix to determine which design alternative best fulfills the goals �

"" "For each design: ���

score "# WF

Step 4: Analysis��

Decision Matrix���

brainstorm to come up with 3+ design alternatives that may meet the goals and fulfill the need: ��•  Briefly describe the 3 alternatives�

•  A previous design or existing commercial solution may be considered one of the alternative designs �

•  Include figures for these alternatives. �•   �•  Discuss any patent-related issues with any of the

alternatives.�

Team Assignment 2: Design Alternatives�

Next, analyze the design alternatives to determine which one best achieves the stated design goals: �

•  Rank the relative importance of the goals, assign a weighting factor to each, & explain the rationale �

•   �•  Determine how well each alternative fulfills each goal.

Explain the rationale for your rating and include any relevant analysis. �

•  Identify which of the design alternatives best fulfills the design goals by creating a decision matrix. �

Team Assignment 2: Design Alternatives�

What if our advisor already has one solution in mind? ��What if the decision matrix selects a design that is different than the one we wanted?��Our need doesn’t have alternative solutions, what should we do? ����
