Solar Turbines: Ancillary Quick Disconnect
2020-2021 - Spring
Team: 16
A vacuum test platform was designed and manufactured in order to test both installation/removal times of clamps and bolts as well as ensure the connection solution maintained a vacuum of up to 4 in Hg. Undermount toggle clamps in combination with a neoprene foam gasket is a proposed solution to replace the current use of bolts and Sikaflex.
Improving Automated COVID-19 Testing Workflows: Pipette Challenge
2020-2021 - Spring
Team: 32
The goal of this project was to optimize COVID-19 testing workflows, allowing for more daily testing and faster results. The problem was boiled down to test tube orientation. The status quo at the EXCITE Lab was for technicians to manually align the test tubes' barcodes in a rack before placing them into a machine that scans the tubes. This wasted about two hours daily. Our solution is a detachable piece that forces the correct alignment of each tube, removing the manual alignment step entirely.
Hamud Universal Upright Vehicle Rack
2020-2021 - Spring
Team: 29
The purpose of this project was to develop a universal vehicle equipment rack that could accommodate various types of sporting equipment. The problem statement was to design and manufacture a modular rack that was: versatile with many types of equipment, durable to withstand a maximum load of 430 lbs, and cost-efficient to be less than current competitors.
Precision Hydrogel Injector
2020-2021 - Spring
Team: 10
We focus on a biomedical device that creates a suction mechanism to grip onto a rat intestine model and is built with an insertion tunnel that allows a hydrogel syringe to inject the fluid at the intestinal site. The 3D printed device successfully gripped the rat intestine underwater, through which 1 μL water with red dye was injected. Red staining of the intestinal wall indicated successful delivery into the submucosal layer.

Wearable Lower Body Negative Pressure Pump
2020-2021 - Spring
Team: 23
Currently, the constant exposure of astronauts to microgravity in space has the potential to cause lasting negative effects on the human body, which include muscular atrophy and even some cardiovascular deconditioning. To combat this, a mobile wearable circulation pump was designed to simulate gravity by creating a negative pressure of 20 mmHg within the suit and reverting fluid shifts in the body.
Brain Organoid Advanced Research Development in Space (BOARDS) Launch Acceleration Simulation Tool
2020-2021 - Spring
Team: 14
The pursuit of space as the next frontier of human exploration raises the question of how space microgravity affects the human brain. To study these effects, brain samples will be sent to the International Space Station aboard a Falcon 9 rocket. However, the high G-forces of a rocket launch may damage the samples. As a result, an acceleration centrifuge simulator was designed to simulate a rocket launch profile to account for these high G-forces.
Optimization of COVID-19 Testing Workflow
2020-2021 - Spring
Team: 6
This project provided two solutions for automating the decapping of COVID-19 sample test tubes in UC San Diego's EXCITE Lab. The goal of the project was to increase overall testing throughput by decreasing decapping time and circumventing limitations on certain equipment.
Bicycle Theft Detection
2020-2021 - Spring
Team: 22
Our device, which can be attached nicely underneath a saddle like a saddlebag, is capable of sensing movement of a bike and sending an alert to the user via text messages. To achieve long operation period, the device is equipped with four solar panels which are capable of not only running the system but charging the battery whenever possible.
Hair Snag Project
2020-2021 - Spring
Team: 28
Researchers studying animals in the wild often use “hair snags”, devices placed in a habitat to collect hair samples when animals interact with them, to collect and study animal DNA. More often than not, current hair snag designs capture hair from more than one individual animal, which makes it harder for researchers to inspect the DNA samples. To correct this issue, we have created a prototype for a single-sampling hair snag that successfully collects and isolates a sample from a single animal.

UCSD MED - Autoinjector for Ultrasound Guided Nerve Blocks
2020-2021 - Spring
Team: 31
This project focused on the development of a medical device to streamline and improve ultrasound guided nerve blocks. These procedures currently require two medical personnel, an anesthesiologist and an assistant. Ideally, this procedure would be performed by the anesthesiologist alone as the forces felt throughout the injection provide valuable sensory information about the state of the operation. Thus revealing the need for an Auto-Injector device enabling this desired one-person operation.
Endoscope Torque Applicator
2020-2021 - Spring
Team: 35
The objective is to design, build, test, and document a device that can reduce the stress on a doctor’s body when performing an endoscopy by applying mechanical advantage while exerting the necessary forces to perform a colonoscopy. The device must be a cheap, disposable tool or a durable, easy to clean tool that can replace the current hand and towel combination. Finally, the device must not alter the overall procedure as that will impose a training cost on the hospital.
