Prototype Project Description

Air-to-Water Drone: When looking at the current drone offerings, there are no options that allow for flying the drone in the air as well as maneuvering it underwater. That is why our team set out to create the solution, a drone capable of doing both! Our research showed that there were challenges to achieve the desired capabilities with the challenge of controlling buoyancy and waterproofing while keeping everything light enough to fly. The research resulted in a united focus to solve these problems, leading to the solution of a using a syringe piston ballast system, waterproof servo motors, inner gasket sealed electronics bay, and silicone sealant for the drone body. Team Members: Austin Mock Kevin Nguyen Paul Velasco Monica Wiewel Arman Zokaeiyazdi Presentation Time: 1:30 pm – 1:40 pm

Compact Disposal Unit: The purpose of our project is to create a trash compactor to compress the trash inside it container by 75%, this can increase the potential of landfill space before it overflow to our street, parks and our water supply. Our product is user friendly, cost efficient, ergonomic, low-maintenance and most importantly it good way to combat pollution. Team Members: Brandon Penesa, Miguel Deniz, Daniel Reyes Presentation Time: 1:40 pm – 1:50 pm

Vented Polar Burner 3D printer: During the 3D printing process heating the air around a part results in stronger more accurate parts however, machines with this capability are mostly nonexistent in the desktop/consumer market because of high cost and patents from companies like Stratasys. A consumer class 3D printer with industrial class part heating would allow anyone to afford strong prints and use advanced materials, the team set out to create a low-cost design that avoided patents. There are two unique design concepts of the Vented Polar Burner, a radial air vent integrated with the print bed, which envelopes 3D prints with hot air, and a heating system designed like a power plant, which utilizes thermal electric heat pumps; Every design element in the team’s printer is built around this with the tradeoff being noise. Team Members: Celso Lara, Jose Robles, Raul Sandoval, Timothy Holandez Presentation Time: 1:50 pm – 2:00 pm

Steam-Powered Engine: The objective of this project is to design a steam-powered engine at the size of a desktop model, with the purpose of educating learners of the inner-workings of a steam engine utilized to generate electricity. Our prototype design consists of a single-acting, reciprocating steam engine on a reproducible scale that can produce the amount of energy needed to charge a mobile device. A dynamo is used to convert mechanical rotation from the flywheel into electric power, and a USB port is connected. Team Members: Frankie Murillo, Jacob Zinger, Aidan VRO, Jared Caldarone, Sean Ward Presentation Time: 2:00 pm – 2:10 pm

Filament Fuser/Winder: After completing 3D prints using a roll of plastic filament, there is usually a remnant of filament that is left over that cannot be used due to how short it is. In most cases, that small piece of filament is thrown away as waste. The objective of this project is to create a device that can either fuse two pieces of filament into a single thread to be immediately used by a 3D printer or fuse the filament and wind it onto a single spool. Fusing the filament as the 3D printer is running can prevent the print failure due to the filament running out. Fusing the filament and winding it onto a single spool helps save storage space and gives the ability to create larger prints. Team Members: Daniel Barfield, Hannah Kotoff, Juliana Resong, Bennet Weiss Presentation Time: 2:10 pm – 2:20 pm

Automatic Sugarcane Juice Machine: The main purpose of our project is to increase operator safety when extracting sugarcane juice. Standard sugarcane machines require operators to manually guide a sugarcane into a set of crushing rollers to extract the juice. To eliminate the possibility of human error and injury, our machine automates the manual sugarcane guiding process through the integration of ramps and a step feeder that individually feeds the sugarcanes to the rollers. Our machine is neatly encased as a single unit within an aluminum frame. It is powered with a DC motor that drives the belt pulley, gears, and rollers. Team Members: Khoa Khuong, Tai Duong, Silvia Preciado, Nguyen Dang, Tuan Nguyen Presentation Time: 2:20 pm – 2:30 pm

CO2 Extractor: The objective of this project is to create a device that would capture and extract carbon dioxide from ambient air, using faradaic electro-swing adsorption methods. The current existing extraction technologies are limited to use in large scale, industrial applications with high CO2 concentration. Creating a device significantly smaller in size, centered on adsorption of atmospheric concentrations of CO2 could create a viable option for more commercial and public use and help to reduce CO2 concentrations in our atmosphere on a global scale. Team Members: James Costley, Kyle Bloomfield, Cynthia Mae Diaz, Seth Herft, Eli Garcia, Maria Chavez Presentation Time: 2:30 pm – 2:40 pm

Fiber-Optic Orbital Debris Detector- Mechanism (FOODD-M): Our project’s mission objective is to take a step towards the future of collecting data on currently untraceable micro-orbital debris that pose threats to space mission safety and success. Our group has optimized a design for an easily manufacturable Fiber-Optic Bragg Grating (FBG) sensor and one-step deployment mechanism to be utilized in a constellation of 6U-CubeSats for the purpose of space observation in LEO. We hope this technology can be further studied and developed to be capable of characterizing impacts by size, velocity, and micro-orbital debris density from the strain of the fiber-optic sensor map. Team Members: Rebeca Griego, Jaylie Galang, Paul Beckwith, Kyle Yang Presentation Time: 2:40 pm – 2:50 pm

The Clipper Cooler: The objective of our project was quite simple. It was to cool down multiple sets of overheating hair clippers in under a minute. There are not any existing solutions that really solved the problem. Until now, after research, design, and fabrication, we came up with the Clipper Cooler. The Clipper Cooler is a scaled down version of an evaporative cooling system that consists of two fans (pull-push configuration), a water pump, and a pack of cooling mesh. A constant stream of water runs through the cooling mesh keeping it constantly dampened while the Clipper Cooler is on. Air is then pulled through the dampened mesh and through the blades of the overheated clippers. The second fan, located on the other side, pushes air out. The Clipper Cooler’s final design was chosen because of its’ multiple clipper capacity. Team Members: Mauricio Delgadillo, Steven Thanh, Kadin Mello, Tung Phan, Michael Nguyen Presentation Time: 2:50 pm – 3:00 pm

3-Piece Motorcycle Helmet: The objective of this project is to allow the motorcyclist to easily replace helmet parts at a cheaper cost rather than purchasing a full brand new helmet. The helmet will provide the user with the necessary safety and protection in the event of an accident. All 3-helmet pieces are connected using tight-hold draw latches, which can easily be attached and reassembled (user-friendly). Team Members: Jessy Vu, Ivan Herrera, Trevor Norman, Fnu Shubham Presentation Time: 3:00 pm – 3:10 pm

Electromagnetic Locking Differential: The objective of our project was to create an electromagnetic locking differential. Enabling the ability to engage and disengage power to the front drivetrain of a Baja vehicle conforming to Society of Automotive Engineers (SAE) rules. Opposed to the SAE team purchasing an off-the-shelf component, our team has designed a system to compliment the current chassis in development for the upcoming competition demanding for a 4x4-drivetrain system. Team Members: Fernando Alcala, Fernando Martinez, Alfredo Alcala Presentation Time: 3:10 pm – 3:20 pm

Upper Arm of Off-roading Suspension System: The ever-growing off-roading industry currently has greater demands than ever before, as each driving team is in search of an edge over its competition. In compliance with these needs, our team has set out to design a lightweight and structurally sound upper arm. Through vast amounts of research and strain gauge testing, our visions as a team have become realities as we look to drive each team to the finish line of success. Team Members: Matt Miller, Juan Lopez, Kevin Shelton, Bryce Roark, Donny Park Presentation Time: 3:20 pm – 3:30 pm

PAC Device - Portable Air Cooler: The need for this project came from the heat wave, which occurred last summer and the widespread use of ac units causing power outages. The need for a device, which provided a cooling effect to ambient air while using only minimal power was needed. Another desired feature was to have the device be small. The vapor compression refrigeration cycle was considered along with the use of thermoelectric coolers. Research suggested that the vapor compression cycle would be difficult to implement and achieve our desired specifications and therefore more research was done on thermoelectric devices. After research on these thermoelectric devices, it was determined to

use these for their simple and small space consumption. Team Members: Charles Gangitano, Israel Morales, Brian Tang, Gilberto Martinez, Ryan Paglinawan Presentation Time: 3:30 pm – 3:40 pm

Lifeguard Drone: Statistics from the CDC states that during the year 2005-2014, about 3500 people drowned each year to non-boating incidents. This number still holds as of today and due to that reason, our project team created the lifeguard drone with the goal of reducing that number. The design is intended to assist lifeguards during rescue operations by designing a buoyant device that can be quickly flown directly to a swimmer in need of help. After reaching the victim, the drone will land in the water and act as a buoy keeping the swimmer above water. Flying the drone to someone in distress will increase the time available for lifeguards to successfully complete the rescue. Team Members: Phu Pham, Gage Scott, Lance Collins, Ryan Hagen Presentation Time: 3:40 pm – 3:50 pm

Improved RTT Bars and Fixtures: Manufacturers have struggled with threads in round bars and bar fixtures from wear and tears as well as high costs from specimen production. Hence, our group has decided to remove threads entirely by innovating a slip insert design and insert pieces. In a way, this offers convenience in time and money for manufacturers. Team Members: Michelle Tran, Tina Hayati, Ryane Kurt, Matthew Sing, Sophia Beshir Presentation Time: 3:50 pm – 4:00 pm

Portable Shopping Cart: The Portable Shopping Cart allows for an easier system of loading and unloading a cart full of groceries. It takes a lot of time and energy to unload a shopping cart at checkout, reload it after checkout, unload it into the car, and then unload it again at home. Our goal was to simplify the process by creating a portable, personal shopping cart that can carry a full load of groceries, collapse, adjust in height, and fit into a car without having to unload the groceries into the trunk individually. Team Members: Alfredo Carrillo, Patricia Brown, Zijie Gong, Rodolfo Hernandez, Guillermo Amaya Salcido Presentation Time: 4:00 pm – 4:10 pm

Functional At-Home Workout Equipment: A functional at-home workout equipment was designed considering both the novice and experienced individuals that are looking to build or expand their personal gym. With a bench and handlebars to compliment the frame, this multifunctional, at-home design accommodates for a wide range of exercises including calisthenics, resistance bands, bodyweight, and weighted exercises. The frame can be used as a standalone feature or accompanied by a bench and/or handlebar accessories. Team Members: Aubrey Chavez, Nallely Lopez, Jessica Ly, Paulina Maldonado, Allan Rojas Presentation Time: 4:10 pm – 4:20 pm

Universal Automatic Windshield Wipers: While automatic windshield wipers have been a staple in most vehicles since the mid 2010's, our group wanted to bring this technology to all consumers while providing it at an affordable price point. This simple system can be wired into any vehicle, while the easy to use connectors can allow the user to transfer this device from vehicle to vehicle with relative ease. After multiple design iterations, our team was able to make a simple and

effective system that can bring any vehicle into the modern day. Team Members: Jordan Murray, Andrew Alameida, Uriel Castillo, Jayson Yamasaki Presentation Time: 4:20 pm – 4:30 pm

Automated Implement Impact Measurement (AIIM): The AIIM (Automated Implement Impact Measurement) addresses an antiquated, dangerous practice of measuring performance marks within the throwing events of track and field competition. Rather than requiring a human official to stand within the landing sector, measurements are made easily using a replacement-landing surface. This surface is comprised of a rigid board combined with four, undersurface integrated sensors. Each sensor is positioned in such a way that they capture any vertical impact energy translated downward through the board, and these data outputs are then utilized in impact triangulation and distance calculation. Our product eliminates the risk of injury during the measurement process, and it further creates a precisely repeatable process without any of the discrepancies associated with human error. Team Members: Juan Ayala, Ryan Coy, Michael Rowan Presentation Time: 4:30 pm – 4:40 pm

Sock Assist: Designing an everyday device that could be used by those with limited mobility in order to accomplish a task that we take for granted every day: putting on your socks. After making different prototypes, we found a suitable one that would meet certain requirements. Team Members: Hyun Wook Ahn, Francisco Hernandez, Francisco Hernandez, Tyler Lansdell Presentation Time: 4:40 pm – 4:50 pm

Active Cooled Chair: The need for staying cool while sitting on an office/gaming chair arose during the transition into working virtually from home. While many people began to seek new chairs, this particular market become essential to our daily lives. However, spending long hours on typical office chairs led to heat buildup and leaving us with sweaty bums. We chose to tackle this problem and introduce an effective way for actively cooling the user with a control at their convenience using the principles of thermoelectric cooling. Team Members: Joseph Kwon, Oscar Sanchez Rodriguez, Fergus Ginther Presentation Time: 4:50 pm – 5:00 pm

Low Cost Ventilator for Emergency Implementation: Amid the pandemic, the high demand for ventilators created a shortage of these devices. As a result, the cost of a ventilator increased making them difficult to obtain. The objective of this project was to create a ventilator that could be a safe and affordable option to the public. This was done by utilizing valves, an oxygen concentration sensor, flow rate sensors, and a microcontroller to monitor and ensure proper delivery of the air to oxygen ratio. Team Members: Dylan Nguyen, Ricardo Orozco, Sovannprina Kiet, Jeremy Wong, Daniel Lim, David Perez Presentation Time: 5:00 pm – 5:10 pm
