BBQ Grill Improvement

mc_logo2Sponsor: Metalcraft, Inc.
Team: David Briggs, Tanner Northrop, Justin Muraski

    Metalcraft Inc. is a sheet metal fabrication and machining company located in Boise, Idaho. They wish to increase the performance of a wood pellet BBQ grill they currently manufacture. Grills of this type often experience non-uniform heating and a slow temperature recovery time after opening the grill lid. The problems experienced are compounded during adverse weather conditions. Using heat transfer principles, subcomponents of the grill were redesigned to address these problems. Through extensive testing we were able to determine which subcomponent design will best resolve the issues experienced within the pellet grill.

Children’s Carseat Rocker

Sponsor: Katie and Wyatt Parke
Team: Erik Larson, Abdullah Sadeq, Mohammed Alghamdi, Tarci Hernandez

     The Parkes are parents who know the challenges involved in soothing and keeping a child asleep. They envisioned a portable device that could interact with an infant car seat to simulate the famously soothing movement of a car ride, while stationary. Thus helping parents achieve a sleeping child with less effort while on-the-go and away from home. The device had to be portable, battery operated, simulate the motion that can be felt in a moving vehicle, strong enough to support the weight and motion of rocking the baby in a car seat, operate in various environments, and with a wide range of car seats. The team approached the idea by working towards a compact design that can fit under a majority of car seats, be carried in a diaper bag, and create 3-axis motion with controllable degrees of intensity.

Connection System for Modular Emergency Housing

College of Innovation and Design logoSponsor: Boise State Shelter Lab Vertically Integrated Project
Team: Amber Salcedo, Jongsang Kim, Zach Fohn

     Shelter Lab is a Vertically Integrated Project out of the College of Innovation and Design. The project focuses on developing a low cost, modular shelter than can be mass produced and deployed following natural and manmade disasters. Shelter Lab tasked the senior design team with the challenge to develop a connection system to attach the roof, walls, and floor of the shelter. This design will help to catapult the rest of the project so the remaining components of the shelter can be designed around the connection system. The team focused on creating a self-contained, toolless, and low cost system that can be easily assembled. Additionally, the connection system developed allows for a wide array of shelter configurations.

Dimethyl Ketone Vapor Smoothing for FDM Printed Parts

TechHelp logoSponsor: TechHelp New Product Development Lab and Boise State MBE Department
Team: Ayoub Alawadhi, Jon Alban, Abdul Altheyab, Chris Brown, Wankun Sirichotiyakul 

     Fused Deposition Modeling (FDM) is an additive manufacturing technology technique used for 3D printing applications. This technique constructs parts layer by layer using a thermoplastic material, ABS being the most common. However, since the parts are built by layers, curved surfaces result in a step like finish posing a problem to the final aesthetics of the product. Our team researched different methods to effectively smooth the surface of an FDM printed part and found the properties of dimethyl ketone to be appealing due to its ability to dissolve ABS plastic as opposed to melting it. A fully enclosed apparatus was designed to vaporize dimethyl ketone, controllably dissolve the surface of a finished part and condense the chemical back to a liquid phase.

High Mobility Wheelchair

Sponsor:  Russell Buschert
Team: Matt DeGoede, Omar Tallab, Hamad Albeshi, Cody Miller

     After an injury, Mr. Buschert discovered some glaring issues with standard wheelchair design. He had a vision to produce an chair which would increase mobility, improve comfort, and utilize a simple design for open source replication and low cost. The team set out to accomplish just that. The ideal chair was created with larger tires to allow increased mobility on all types of terrains, an air shock for improved comfort and economically sensible components to make cost affordable for an open source design. The finalized design of the chair will help to reduce the amount of fatigue the user experiences in day to day activities and allow them greater accessibility on non paved surfaces.

Induced Airflow Product Sorting

Sponsor:  Boise State Mechanical and Biomedical Engineering
Team: Mohammad Ali, Abdullah Almuthen, Joe Ferrin, Jody Hooyboer, Pete Marting

     One of challenges of harvesting agricultural products is sorting the final product from the dirt, sticks, and rocks that surround the product. The client has asked that the team investigate the use of an induced air flow to improve this process. This would move the fan out of the air stream and prevent tare from getting pulled through the fan, damaging the blades and motor. The team has focused on trying to understand how to induce air flow and also how to optimize the volumetric flow rate of the induced air flow. They have also looked at how to use this airflow in product sorting. To do this, a series of testing devices were built culminating with a test stand designed for a wind tunnel at BSU. Various orientations were tested with flow velocity and pressure be collected throughout. Final analysis was completed to determine optimum geometry and controlling parameters.

Moving Target Design

MGM Targets LogoSponsor: Michael Gibson Manufacturing, Inc.
Team: Yousef Alabbad, Kelly Harrigan, Kaleb Churchman, Michael Travis, Gage Roberts

     Problem: MGM Targets is looking to design a moving target to be used for long-range rifle training. The design needs to run autonomously on rough terrain, following a straight line back and forth robustly for several hours, and have a start/stop function that can be controlled from a distance. It also needs to be easy to set up, durable, and affordable. Tasks accomplished: The final design consists of a chassis that will carry the target perpendicular to the shooter with a mechanical guidance system. The moving target was assembled and tested to verify the design.

Ultralight Backpacking Chair

Logo - TD Development and DesignSponsor: TD Development and Design
Team: Bryce Grigg, Kalin Gibbons, Katie Yocham, Clayton Kezerle

     Enthusiast backpackers work toward minimizing the weight of what they carry when embarking on a trip. A camp chair is an item that greatly benefits the comfort of a backpacker but is often too heavy to bring. TD Development, LLC wants to design the best camping chair for the ultralight market. The chair consists of an elevated seat with lumbar support which folds into a compact form. The ultralight chair is competitive in the current market, weighing approximately 16 oz. We have improved on the current market designs by using novel materials such as pultruded carbon fiber and a tensegrity concept.  We would like to thank our instructor and Travis Dean of TD Designs for their support and valuable insight.

Wash Station

MGM Targets LogoSponsor: Michael Gibson Manufacturing, Inc.
Team: Juan F. Luna Jr., Abdullah Alghamdi, Colton Streufert, Muhammed Alzahrani

     Mike Gibson Manufacturing (MGM) is a company located in Caldwell, Idaho, that produces shooting targets for training and recreational purposes. Many MGM products require steel tubing for brackets, stands, and linkages. Grease covers most of the steel tubing, and must be removed before production. The old process involved a lot of hand cleaning and pressure washing one steel tube at a time. This project focused on the design of an automatic wash system that would pull dirty material in one side, and push it out the other ready for production. The design consisted of multiple support tables to accommodate 20 foot lengths of material in quantities up to 60 tubes, a conveyor system, a wash system, and a water collection and filtration system. The final design was built and tested before being delivered to MGM for immediate use.

Water Knife Roll Sizer

Image of the ConAgra Foods logoSponsor: ConAgra Foods/Lamb-Weston
Team: Juan Arrieta de Angulo, Hadi Bin Abdullah Aldees, Mohammad Bin Naji Alotaibi, Samuel R Barker, Michael Deane Chapple

     ConAgra Foods Lamb Weston utilizes a diameter sized grader to sort and distribute the right size potatoes to the right place. This machine experiences frequent failures to the drive system that cause unplanned maintenance and downtime costing the company substantial amounts of money. The SIZE Team examined and studied the equipment in operation and the history of failed parts in order to determine the root cause of failure. A smaller scale machine was designed and manufactured by the team in order to test and analyze different drive configurations and determine the best solution to mitigate the failures.
