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.

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.

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

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
