Putting Theory into Practice

Published May 1, 2018

A locomotive suspension system for harsh environments was chosen as the most innovative and practical design and a turbine in-pipe system as the best design for sustainable and clean energy harvesting at the Engineering Innovation Expo Monday.

The showcase in the University Student Union included 22 Senior Design Projects from the CSULB Mechanical & Aerospace Engineering Department.

The pico hydroelectric turbine-in-pipe system uses excess pressure within residential-scale pipe systems to harvest electricity off-the-grid. The system consists of a reaction turbine, generator, and auxiliary electrical equipment. The electrical equipment is dependent upon the application which can include powering outdoor lights or charging small electronics. Additionally, the design of the system will keep the flow rate and pressure of the water entering the household in compliance with standards for potable water systems. Team members include Cristina Azuara, Hope Daley, Elyssa Lawrence, and Daisy Zaragoza.

The locomotive suspension system design uses components that are low maintenance, easy to dismantle, and flexible enough to operate over rough and fluctuating track conditions, and cost effective for the export market. Team members are Austin Ralph, Alexander O’ Donnell, Jared Malabed, and Jacob Bostrom

The other teams were:

Natural Gas Production from Waste Food

This anaerobic digestion system shows a viable and affordable way for university campuses and other small communities to recycle organic waste to produce natural gas. The gas is filtered to output methane, which can then be applied to provide heat or electricity to the university campus. The benefits of this alternative energy source include saving the environment from unnecessary waste and lower energy costs. This prototype is a micro-grid model of a compost digestion chamber with a gas filtration system that can be scaled up to fit the needs of customers.

Low NOx Hydrogen Natural Gas Mixture Fueled Burner

Our team contributed to the research, manufacturing, and testing of a burner capable of using mixtures of natural gas and hydrogen. The results of this study have significant impacts on controlling NOx emissions during combustion, which is critical in minimizing the adverse impacts on the environment. The successful completion of this design would help provide a tool that uses different blends of natural gas and hydrogen mixture, while limiting the NOx emissions.

Team Members: Karla Duenas Zuniga, Adam Still, Chris Asfour, and Hanif Payandeh (BSChE)

Hydrogen Pipeline Installation

The purpose of the project is to develop a method to install a hydrogen pipeline in an existing natural gas pipelines. To achieve this, a pipe was made out of High Density Polyethylene (HDPE) reinforced with fiberglass. HDPE was used to ensure that hydrogen gas doesn’t diffuse through the pipe walls, while the fiberglass reinforcement ensures that the pipe is capable of holding 1000 psi. Our project will help cut down the time and cost required to create new pipelines by eliminating the need to dig new trenches.

Multipurpose Air Duct Surveying Rover

This rover will improve mechanical surveying of buildings. In hospitals, prisons, and universities, some areas that ducts wind through can’t be easily accessed due to older building standards and regulations. Sometimes what sounds like a simple task requires hazmat suits due to asbestos. This rover is equipped with a light and camera for navigation, but also surveying equipment to determine its exact location inside of the space, relative to a predetermined zeroed location. This rover differentiates itself from others in its ability to ascend a vertical shaft, either cylindrical or rectangular. The arms are spring-loaded to adjust to a changing duct size. This rover so far can’t achieve many of its lofty goals, but it can move, (albeit not by battery power), overcoming the challenge of providing motion to this unique design. With this working, the planned features can be upgrades onto an existing platform.

The Pillar

The objective of this project is to create a solution for users, particularly elderly citizens, who are required to take multiple different pills a day. By creating and optimizing a machine that will be safe, reliable, and user friendly, their pill taking regime will be simplified. By decreasing the amount of time and effort needed to sort and organize their pills, we hope to improve their day-to-day life. The device will have the capability to sort up to 16 different types of pills and detect when a pill has been dispensed.

Charge Cart

In order to relieve the pressure of the increasing demand for electricity, a pulley system that can be easily attached to a shopping cart was designed. The driven wheel of the pulley system drives a generator shaft, which generates power that is stored in a battery. The battery can then be used to charge handheld devices such as cellphones and tablets.

Energy Generating Exercise Machine Using Wells Turbine

The Wind-Powered Workout Machine is an exercise machine that generates power using Wells turbine technology. A cable that is pulled during exercise lifts a piston that exhales and inhales air through a vent powering a bidirectional turbine to generate enough power to charge four smartphones simultaneously. The machine has the capability to perform various exercises such as lateral pull down, rowing, bicep curls, and much more. The machine is different than any other type of energy-generating exercise device in the market, since its primary focus is in building muscle rather than providing a cardio exercise.

Concentrated Solar-Thermal Energy Collector

A solar thermal collector captures sun’s heat  to convert to useful work. A parabolic trough collector is a curved mirror that focuses the sun’s radiation to a focal point, where fluid running through a pipe absorbs the heat. The trough was designed to optimize energy collection potential and test the feasibility of a home installation for space heating and heating hot water.

Team Members: Esteban Martinez, Graham Schafer, Randy Vu, Joseph Cruz, and Thomas Anderson

Automatic Lead Belay

The Automatic Lead Belay provides lead rock climbers a way to climb safely on their own and prevent a fall. A 250-pound climber could safely lead climb and descend at their discretion. To prove the concept, we fabricated a 3D-printed, scale model to safely withstand a 25-lb. weight. This prototype comes with a centrifugal mechanism that activates a rotary damper to increase  drag force, slow down the rotational speed, and safely lower the climber in the event of a fall.

Smart Trash Can

The Smart Trash Can incorporates a PIR sensor-activated vacuum at the base to help get rid of debris such as dust or trash that may end up on the floor. This will remove the need to bend over with a dustpan to sweep up trash on the floor, allowing for the consumer to move on with their day. A distance sensor is integrated in the trash can to automatically open the lid with a simple gesture and one more integrated inside to show the user how full the trash bin is through a small LCD screen.

Team Members: Jose Nuno, Luis Torres, Marcos Barajas, Sahiru Liyanage, and Williams Rosas

Skateboard Generator

The Skateboard Generator was designed to save your phone or tablet from dying in a time of need. The idea came from wanting to create power from an everyday item that is used by students. Everyone has to deal with limited battery supply and with the advancement of technology increasing every year, battery life seems to be getting worse. The gear that is integrated into the wheels will spin a belt that is connected to a smaller gear which will spin the motor which will charge a portable power pack. Once the power pack is charged, unplug it from the skateboard and use it as a power source for your phone, tablet, laptop, etc.
