Manufacturing Engineering

These projects are part of a one-semester only sequence. They are functionally complete.

Solar Car Challenge


Sponsor: Texas State University

Student Team: Manuel Garcia, Daniel Ratcliff, Matthew Park, Adrian Dominguez

Faculty Advisor: Mr. Nathan England

Electric vehicle technology is of high importance to automobile manufacturers and consumers because it provides an environmentally friendly means of transportation. This Texas State Senior Design team is tasked with designing and integrating the vehicle's braking system, mounts for pedals, batteries, and control modules onto the existing chassis. The braking system will consist of a hydraulic braking system, and a mechanical emergency braking system. The mounts for the control module, batteries, and pedals will be designed with CAD software and then manufactured to be integrated onto the existing chassis. Using DFMA principles the team will design a braking system that is safe, efficient, and affordable. To ensure the braking system and mounts are compatible with the powertrain components the team is working concurrently with electrical engineering teams that are designing powertrain components.

Three Wheeled Wheelbarrow Analysis


Sponsor: Majineering Product Design – Mr. Milton J. Vaverek

Student Team: Cesar Sifuentes, Madisen Weaver, Emily Rice, Isac Giron

Faculty Advisor: Mr. Mark Summers

The goal for Majineering is to produce a kit for customers to install on existing standard wheelbarrows and transform them into a wheelbarrow with two additional “training” wheels. The company plans for the kit to be easy to manufacture, install for the customer, and ship. This design provides many improvements to the standard wheelbarrow, including stability, height adjustable handles, and an automatically locking parking break.

This project is focused on performing a structural analysis on the lever and crossmember joints of the designed wheelbarrow handles, when exposed to a 500-pound load. The team will also investigate two different gauged rectangular steel tubes to find the least expensive option for manufacturing. Lastly, the team has been asked to optimize the bending manufacturing of the rectangular tube component and perform the bending at a 14° radius. There have been issues in the past with a wall thickness distortion, the team wants to prevent this occurrence.

Mechanical Watch Case Design


Sponsor: Texas State University

Student Team: Alec Chamberlain, Joshua Jennings, Kevin Diaz

Faculty Advisor: Dr. Rich Compeau

Before the days of the quartz driven watch, nearly all watches were mechanical. When the quartz movement was developed, mechanical watches were largely replaced, and many mechanical watch manufacturers went out of business. As a result, most watch companies started purchasing their mechanical watch movements instead of manufacturing them in-house.

This project focuses on developing a watch case that can fit a mechanical movement, specifically the 6498-1 movement. By developing this watch case we would be able to produce a quality watch with customizable features at a fraction of the price. The watch case will be water resistant, protect the movement while ensuring proper function, and be aesthetically pleasing. The final product will be cut using the 5-axis HAAS CNC machine.

Innovations in Ultrasound Tests for Vascularity Research


Sponsor: Texas State Exercise Sports Science: Dr. Stacy Hunter, James Shadiow

Student Team: Nicole Block, Daniel Valdez, Aleksandar Sike

Faculty Advisor: Mr. Mark Summers

Members of the Exercise and Sports Science Department are researching nitric oxide levels in the human bloodstream to gain information regarding vascularity. They are currently using an ultrasound probe that is being held by a multi-joint arm that is failing to meet their needs. This project focuses on designing and producing a new and improved Probe Holder. Focusing on three main areas, the product will be able to perform quality tests, will be cost efficient, and will be reproducible.

HVAC Automated Drain Line Cleaning System


Sponsor: Visionex Holdings LLC

Student Team: Wesley Howard, Deola Aina, and Justin Ratcliff

Faculty Advisor: Mr. Mark Summers

Visionex Holdings, in conjunction with Texas State Senior Design Team, is developing an automated product with the capability of cleaning an HVAC condensate drain line. This project addresses the need that home and business owners have expressed for a system to clean the interior of a condensate drain line by removing any algae growth inside it. This will prevent blockage of the drain line and consequently overflow of fluid, resulting in cost savings of roughly $250/year per building as a result of eliminating the need to call a plumber. This project is focused on developing a prototype with the functionality to automatically power on at least twice a year, each time cleaning the drain lines in under one minute.
