Portfolio of projects ranging from reverse engineering to package development and algae harvesting.

2. ABOUT ME
My name is Gabriel Gonzales and I am currently a student at New
Mexico State University, obtaining my B.S. in Mechanical Engineering
Technology. I am seeking a position where I can begin a career in
product design, research & development.

4. Shell & Tube Boiler/Condenser
• For my Capstone Project, myself and two other group members were given the task
of building, testing, and determining the feasibility of a Multi-Stage Vacuum Still to
purify water.
• Using concepts in Patent No. 8282791, which outlines the details and concept of a
naturally maintained vacuum still, our group designed and simulated various
designs using Solid Works to determine which would best meet our goals.

5. Shell & Tube Boiler/Condenser
• Using Solid Works to design and
perform flow simulations, our Capstone
team developed several iterations
before we achieved a design that met
all our specifications
• A scalable prototype is currently being
built to perform required tests.

6. Procter & Gamble
• For my summer internship at Procter & Gamble, I was given the task to develop a new
Variable based test method for determining blistercard seal integrity.
• The blistercard seal integrity test method was an Attribute based test which did not
provide enough granularity to fully understand the seal qualities of blister packaging.
• Furthermore, an Attribute based test requires a large test size, which means a large loss of
product occurs.

7. Package Test Development
• In developing a Variable based test, I leveraged technical curiosity to determine areas of
improvement and implementation of current tests based off of ASTM test standards.
• Once an alternative method was agreed upon, I validated the process through a design
of experiments and statistical analysis of the test data.
• The overall outcome of my efforts was the development of a statistical model that was
able to determine and predict failure percentages based off of various seal qualities.
• At the end of my Internship, I made recommendations on how to incorporate the
alternative test method based off of final results.
• Alternative test method reduced test size, costs, and allowed a better understanding of
seal qualities.

8. • Dissolved Air (Micro Bubbles)-Density Improvement
• DAF (Dissolved Air Floatation) technology is used to harvest algae.
• The method being used to inject the Dissolved Air solution was not
efficient as air was settling-out of the, thus decreasing harvest efficiencies.

9. Harvest Process Development
• After evaluation, it was determined that the location of injection and the method
of maintaining pressure was the cause of the absence of dissolved air in the main
chamber.

• New injection points were created to inject directly into the the chamber.
• Also, I determined that maintaining pressure at the injection points prevented
air to settle out of the solution.

11. Harvest Process Development
• After testing and evaluation, saturation of air throughout the chamber
was achieved.
• Thus increasing the efficiency and overall performance.
– Efficiencies increased to an average of 90%

12. Kinematics-Reverse Engineering
• One of the projects assigned
in my Kinematics course was
to reverse engineer a basic
kinematic machine as seen
here.

13. Kinematics-Reverse Engineering
• The outcome of my efforts was an interchangeable crank
and slider mechanism as seen here.
• Measurement points were incorporated into the design
in order to be able to measure angular and linear
displacement, velocity, and acceleration.
• Interchangeable links were also designed to compare the
effects of using straight, angled, or curved links.
