Designing a New Drug Delivery Device
An application of “design & build” principles
Betsy Ameen and Chris Lundberg
New Advances
Where do ideas come from?
How do you know if an idea is good (or not)?
How do engineers develop and test their ideas?
Why Design & Build? It’s fun!
It applies science to YOUR daily life
New advances are unique; we remember the strange and different…
… so we can tie methods of inquiry and design to the study of biotech advances.
Designing a New Medical Device
Think how the scientific method and then “design & build” relates to the process of invention
Science and Technology: A convergence
ofLife Sciences Nanotechnology
Biotechnology Adv. Materials & Production

How do New Inventions Happen? Close observation Sheer dumb luck – timing Motivation -- $ ? Search for an answer to a problem Creative approaches and strategies By asking, “what if?” and Brainstorming Using “models”… followed by a period of testing or scientific
analysis.
The Engineer’s Design Process
Identify the Problem Brainstorm Design Build – Test – Evaluate – Redesign Share Solution
Inventions:
are PRODUCTS we create which are… Unusual
Appropriate for a job
Transformed from something else
Condensed (refined after testing)
Finding Your Problem
Make a “bug list” of things that bother you…
What “bugs” you? What can you improve? Pills too large? Unwieldy or impractical devices? Invasive or painful? Expensive medications?
You can come up with an idea from your bug list!
More Ways to Develop Ideas
Combine Opposites!
What is exactlyopposite to myidea that I couldsomehow combinewith it?
Idea
Opposite
And More Invention Ideas!Use the SCAMPER Method:For my idea, what can I …. Substitute Combine Adapt Modify – Magnify – “Minify” Put to other Uses Reverse or Rearrange … to make it WORK!

The Process of Invention and Science An idea (or problem) = hypothesis
Develop a “bug” list = observe/describe
Build/design = testing
“Back to the drawing board” = rethink hypothesis and try a new variable
Establish criteria to evaluate = analysis of results
Will the public buy it? = conclusion
Your Task in this Session:
Design a new medical device that will solve a problem (or improve upon an existing solution)
Create a prototype of your design that will model what it will look like and how it will work
Share your creations with the class!
Once begun is half-done!
“If I have a thousand ideas a year, and only one turns out to be good, I’m
satisfied.”
Alfred Nobel
