Northwind Inc
Internship
Root Cause analysis
Problem
• Automated well, pipe, pump, and
filter system producing data
discrepancies. Tasked to
troubleshoot a complex
automated water treatment system.
Solution
• Used RCA to design testing
procedures to be used in any
current and future gauge, pump
controller, and connection analysis.
• Discovered and corrected a meter
which had been programed
incorrectly.
Accomplishments
• Gained extensive experience with: • Implemented Design
• Transducers
• Valves
• Pumps
• Piping
• Wells
• Filters
• Meters
• Gauges
• Ladder Logic Programing
• CAD Drawings • Product Spec Sheets.
• Completed all work in an
independent, timely, and efficient
manner. Produced detailed design
reports including methods, analysis,
and results. 3
BYU-I
Educational
Projects
“EZ TRAC”
Fender Tire Chain
system
Project Goal
• The proposal was for the design
and construction of a semi-automatic or fully-automatic truck
and trailer chain installation and
removal device.
Design Outcomes
• Fully functional prototype
• Chaining process time decreased
by 80%.
• First Place at BYU-I Research and
Creative Works Conference for
junior mechanical engineering
product design.
Personal Contribution
• Presented initial proposal.
• Assigned to Lead the team.
• Lead concept generation and
selection with the use of HOQ,
Pugh chart, FMEA, Selection
Matrix.
• Assisted in 3D CAD design
creation and iteration using
Autodesk Inventor and Solid
Works to achieve fit and finish.
• Preformed all Iterative ANSYS
Finite Element Analysis for stress
and deformation requirements.
• Worked with team members to
fabricate, install, and test
chaining system. • Created Project reports to
update progress.

“SWAT Bot”
Mechatronic Tactical
Reconnaissance Robot
Project Goal
• Rexburg, Idaho SWAT team
requested a durable remote
controlled camera to view the
interior of a house before entering.
Design Outcomes
• Fully functional prototype allowing the device to easily drive wirelessly
and feed a live video back to the
driver.
• Third Place at BYU-I Research and
Creative Works Conference for Senior mechatronic product
design.
Personal Contribution
• Worked with team members
concept generation and
selection.
• Preformed all 3D CAD design and
iteration using Solid Works to
assure adequate space for
components.
• Assisted in writing Arduino programing and constructing
circuits.
• Fabricated, constructed, and
tested SWAT Bot frame.
• Created project video for
presentation.

“Bone Crusher”
Kinematic Can and Bottle
Recycling Compactor
Project Goal
• Assigned to build a five bar linkage to preform and every day task.
Design Outcomes
• Fully functional prototype allowing
a small child to crush a can with
over 70 PSI of force .
Personal Contribution
• Worked with team members to
brainstorm concept selection.
• Assisted in 3D CAD design using
SolidWorks, and preformed a
motion study to predict velocity and acceleration.
• Used CAD drawings to fabricate,
construct, and test Bone Crusher
with the help of my own four
small children.
• Presented device to a class of peers.

Jack Tester
Project Goal
• To design and construct an frame that could be built and used based
on CAD drawings alone.
• Jack tester required to hold up
under load in high and low
positions.
Design Outcomes
• Easy to build frame with minimal
machining operations
• Device maintained integrity under
excessive load.
Personal Contribution
• Worked with a team in concept
generation and selection .
• Assisted in 3D CAD design using
Solid Works to create DXF file for
plasma cutter. • Preformed Finite Element Analysis
for stress and deformation
requirements using Autodesk
Inventor.
Miniature Cannon
Frame
Project Goal
• To design and mill twenty cannon
frames that could be milled on a
CNC Machine. • Frame required to fit in a final
assembly.
Design Outcomes and
Personal Contributions
• Modeled frame set in SolidWorks and imported to Master CAM to
program and obtain G code file for
mill.
• Assembled frame with parts for
twenty complete cannons.

Hagen Potato
Sizer/Sorter
Design Optimization
Project Goal
• Optimize the production volume of
the Hagen Potato Sorter at Wada
Farms in Blackfoot, Idaho.
Design Outcomes
• Root Cause Analysis resulting in
many test design iterations.
• Solution increasing production
efficiency and resulting in an increase of approximately $3.5
million annually.
• Completed project on time and
significantly under budget.
• Second Place at BYU-I Research
and Creative Works Conference for senior mechanical engineering
project design.
Personal Contribution
• Voted team leader.
• Worked with team members to preform a functional
decomposition of a complex
optical sorter.
• Worked through a Root Cause
Analysis.
• Assisted in 3D CAD creation using
Solid Works to demonstrate the
system organization.
• Worked with team members to
plan, perform, analyze each test.
• Created Project reports to explain RCA process and progress.
• Created project video to
demonstrate process and solution.
