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.

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.

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.

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.

Blister Packaging-Test Development

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.

• 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.

Harvest Process Development

No Dissolved Air (Micro Bubbles) are seen in the Chamber.

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.

Harvest Process Development

• 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.

Injection points with valves maintaining desired pressure.

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%

Complete saturation achieved!

Kinematics-Reverse Engineering • One of the projects assigned

in my Kinematics course was to reverse engineer a basic kinematic machine as seen here.

Crank Slider

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.
