My Background BS Biomedical Engineering from UCONN in 2006
MAT Middle School Math and Science from AASU in Savannah, GA
Currently working on Masters in Materials Science and Engineering at UCONN
Interned at Covidien 2005 and 2006. Returned to Covidien in 2009 as a Product Development Engineer
Covidien Corporate Overview
Covidien is… A global medical device and pharmaceutical manufacturing company with
over $11 Billion in annual revenue
Well positioned with a diverse portfolio of products and technologies in attractive franchises
A company with a history of quality and innovation
Highly efficient and productive, producing strong margins and cash flow
A leading player across our portfolio
What does Covidien mean? “Co,” from the Latin word for together
“Vi,” from the Latin word for life
Covidien is a unique name in our space within the healthcare industry – and it is designed to stand out from our competitors
An ongoing partnership in the lifesaving work of medical professionals, creating far-reaching benefits for improved
patient care
What is the significance of the Covidien brand icon?
Two bracketed "C's," representing Covidien's core values of Compassion and Collaboration
Visually embodies support and integration
The two “C’s” of Compassion and
Collaboration
Our Mission and Vision
Create and deliver innovative healthcare solutions, developed in ethical collaboration with medical professionals, which enhance the quality of life for patients and improve outcomes for our customers and our shareholders.
Deliver unmatched value to our customers by providing solutions that improve patient outcomes and healthcare delivery through clinically relevant and economically valuable innovation.
Our Mission
Our Vision
Strong Line-Up of Well Recognized Brands
Engineer in Residence Program This program is designed to send one to two Covidien engineer(s) to UCONN
per week throughout the academic year. This engineer will provide senior design project support.
Align senior design project syllabus with engineer skills so proper help is provided throughout the various project stages.
First semester we will be at UCONN on Wednesdays. Present from 12:00-1:00
Office hours from 1:00-4:00
Extra credit available for participation.
Disclaimer: Although we are all professional engineers our expertise tends to be in areas that we work in consistently. We do not know everything, but promise to help as much as possible and point you in the right direction if we don’t know.
Engineer in Residence Program Topics Creativity Tools and Concept Selection
Product Development Process/FDA for Medical Devices
Rapid Prototyping/Machining: Methods and Design Guidelines
CAD Basics
How to Read Engineering Drawings
How to Create Engineering Drawings
Design for Manufacturing/ Design for Assembly
Concept Creation and Selection
Why do we need to learn about creativity? Thomas Edison and the light bulb filament:
"I have not failed 10,000 times. I have successfully found 10,000 ways that will not work."
Do you think this trial and error approach would be acceptable in the business world?
We need to be innovative, but at the same time efficient
Must have tools at our disposal that help us: Remove our bias
Think outside the box
Bring novel ideas
Be more efficient

Some simple creativity tools… Process Mapping
Brain Writing
Process Mapping
Should describe: Major activities/tasks
Sub-processes
Process boundaries
Input variables (X’s)
Output variables (Y’s)
Can help determine proper scope of project
Shows unexpected complexity, problem areas, redundancy, unnecessary loops, and where simplification may be possible
Great for laying out functions of a device, steps of a test method, etc.
As more information becomes available, the map can be updated to verify the scope is controlled and correct for the design objectives
Needs to be routinely updated
Process Mapping Symbols
A step in a process
A decision or multiple choice
A path (flow) from one step to another
Start, Stop
Storage or inventory
Delay

Brain Writing (6-3-5)
An alternative to traditional brainstorming
Ideas are written instead of spoken
Encourages building on others’ ideas
Good for introverted personalities
1. Everyone gets a brain writing form
2. Write 3 ideas across the top row
3. Allow fixed time intervals (5 minutes)
4. Rotate forms through group
5. Review ideas of previous person
6. Either expand on previous person’s idea (use arrows to show the flow) or write new ideas
7. Keep passing sheet until all participants have received each sheet

Other methods to look into… TRIZ- Theory of Inventive Problem Solving
A problem-solving algorithm developed by a Soviet inventor based on extensive research of global patent history
1. Problems and solutions repeat across industry and science
2. Patterns of technical evolution also repeat across industry and science
3. Innovations used scientific effects outside of the field in which they were developed
http://en.wikipedia.org/wiki/File:TRIZway.jpg
TRIZ Continued (www.triz40.com) Basic principle that inventive problems stem from contradictions such as, “I need a longer
instrument shaft, but need to minimize its weight.”

Concept Selection: Pugh Matrix Developed by Stuart Pugh
Used to compare alternative design concepts
Comparisons based upon design requirements
Results can be single or reduced number of concepts
Pugh Matrix Steps for Application1. Determine the design requirements
2. Identify competing designs with a small phrase or picture
3. Create a matrix with1. Requirements on left
2. Design concepts on the top
4. Establish a team mutual understanding1. All requirements
2. All design concepts
5. Weight the design requirements on a 1, 3, 9 scale if necessary
6. Rate each design’s ability to meet the requirements1. Rank 1-3 (3=best, 1=worst)
7. Multiple weights by rating and sum each column to determine superior design
8. Evaluate each concept for “hybrid potential”

Conclusions Concept creation tools help eliminate bias and provide a systematic
approach to innovation
Process mapping, brain writing, and TRIZ are just a few of the many tools available
Once concepts are created, a Pugh matrix can help rank concepts to determine the best solution or hybrid solution
