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.

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
![Page 16: Engineer in Residence Program: Concept Engineering Emily Davis Covidien 9/12/12.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce65503460f949b3b2d/html5/thumbnails/16.jpg)
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
![Page 17: Engineer in Residence Program: Concept Engineering Emily Davis Covidien 9/12/12.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce65503460f949b3b2d/html5/thumbnails/17.jpg)
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
![Page 20: Engineer in Residence Program: Concept Engineering Emily Davis Covidien 9/12/12.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce65503460f949b3b2d/html5/thumbnails/20.jpg)
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
![Page 22: Engineer in Residence Program: Concept Engineering Emily Davis Covidien 9/12/12.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce65503460f949b3b2d/html5/thumbnails/22.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
![Page 24: Engineer in Residence Program: Concept Engineering Emily Davis Covidien 9/12/12.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649ce65503460f949b3b2d/html5/thumbnails/24.jpg)
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
