Abstract

The Auto-Trache is an emergency medical device that trivializes the tracheotomy process, allowing for rapid implementation even by individuals with no medical training. The simple operation allows someone to use it on themselves if the situation demands.

A constricted airway encountered by choking individuals, anaphylactic shock sufferers, and other victims must be cleared immediately to prevent death. When the Heimlich maneuver is insufficient, the only alternative is a tracheotomy. Untrained individuals are likely to cause harm when performing a traditional tracheotomy. The Auto-Trache device reduces the chance of unintended trauma, increasing the odds of survival.

Blocked airways can occur during surgery, leading doctors to perform tracheotomies mid-operation. When oxygen is cut off from the brain, seconds matter. The Auto-Trache’s ability to breach the throat and open an airway near-instantaneously gives doctors an edge.

Auto-Trache, because every second counts.

Abstract

With an increasing interest within society in alternative energies, the BE-Wind turbine is a small vertical axis wind turbine that can fill some of the future need for energy production. The purpose of this project is to make modifications to the turbine that will make it more efficient.

By changing the aerodynamics of the front facing shield and adding a weather-vane to allow for a better turn speed of the turbine we hope to achieve this increase in efficiency.

The size of these turbines allow them to be placed in much more urban settings. With better availability for locations and an increased efficiency in power production, these turbines will be a good solution for those who wish to help with reducing the carbon emissions we currently produce.

Abstract

Our project with Brewer Science involves improving their lithography chemical bottling operation via automation. We are confined within cleanroom, OSHA, and physical constraints when considering improvements to their current process. The main goal of the project is to cut down on the amount of human input needed to perform the bottling operation. Brewer Science's current machine is designed to do three functions, decapping, filling, and recapping the bottle. However, only one of these functions are done in the machine that they use currently, which is filling. The other two operations are currently done by hand because they do not function properly, and therefore are very time consuming. The bottles must also be labeled and scanned prior to entering the machine. These two functions are also done by hand.

We have identified a number of points in the process where we believe that time could be reduced. Several solutions have been developed that we believe will be able to cut back on the downtime that the current operation faces in addition to proposing a parameter modification in the control system that oversees the operation. We hope that Brewer Science will utilize or improve upon the solutions that we have provided for their operation.

Abstract

C&S Propeller specializes on maintenance, repair, and overhaul of the 54H60 propeller system. Our project consists of resolving two separate problems during the overhaul process. First, we must design a race protection cover that will resist etch and corrosive chemicals. Currently, the technicians are manually taping every inch of the ring, which is a very tedious and time consuming process. Our goal is to design a cover that is lightweight, easy to handle, and most importantly able keep the ring completely dry. With the use of this ring protection cover, we will reduce the time is takes to prepare the ring before FPI and anodizing processes.

Second, we must run stress analysis on the press fit bushing that transmits high torsional loads from the hub to the blade. Technicians are currently reaming the taper bore press fit area and scrapping the whole blade after becoming out of tolerance on critical dimensions. The goal of our analysis is to design an oversized tapered bushing that will meet all military/FAA standards. With the use of this bushing, wesave a very expensive blade from being scrapped and adding an additional flight life cycle for each overhauled blade.

Abstract

One may believe a building is always operating the most efficient way, however that is not always the case. Some facilities are not properly commissioned or do not have their energy data analyzed frequently. The result, the facility’s equipment becomes less efficient and continues to accumulate excess energy. One of the best ways to lower energy consumption and operational cost in a building is to perform an energy audit, and determine how a facility can become more efficient by implementing energy conservation measurements(ECM). Our senior design group was determined to help the University of North Texas by creating a utility assessment report (UAR). A UAR is a report which includes the facility’s current energy consumption, a list of ECMs that would benefit the facility, and the total energy saving after ECMs are implemented. E3 contacted the University of North Texas to discuss this senior design project and UNT agreed to provide the Business Leadership Building for this project. UNT assigned E3 the Business Leadership Building (BLB) due to its high energy usage and need for an energy audit. Our group created a base model using eQuest and an ECM model with ECM’s implemented. One of our goals is to demonstrate that a fairly new facility can consume an excessive amount of energy and become more efficient after implementing ECM’s.

Abstract

We worked with Huber Engineered Wood out of Broken Bow, Oklahoma to create a testing device for ASTM D1037 and PS2-10 Swell Tests that accommodate a larger range of Huber products. Currently the samples that do not fit within the current device are measured by hand. To fulfill the needs of Huber, we went about expanding upon the device that they currently use to allow larger variety of products to be tested. With this redesign, Huber can measure boards up to 2 inches thick with precision and accuracy. The device had to work with current lab set up while also being easy to implement. The Edge Swell testing device is useful to Huber as it allows them to have an elevated level of accuracy and precision for testing samples that have been previously out of size for the current means.

Abstract

There is an emerging problem in the world with the continuous rise of temperature, the planet is becoming warmer and thus the climate is changing. The burning of fossil fuels is the primary source of energy that is used to power the daily functions of our society. There are alternative paths that as a society can be used in order to stop or reverse the damage that has been caused by fossil fuels. The energy provided by the sun is an immense unexploited natural resource that can power the entire word; therefore, the purpose of this project is to help and contribute to emerging technological industries harvesting solar energy as a source of power. Our senior design team is in the process of integrating a solar cell into an existing thermoplastic roof material that is currently installed individually in commercial buildings. The main goal is to make the vast rooftop of commercial buildings harvest the solar energy.

Abstract

Micro Forms purchased a camera system that will inspect every part produced. Due to their inefficient lubrication method, too much fluid is splattered onto these cameras, making them inoperable. The goal of our project is to design a lubrication system that can be accurately controlled and improve quality control. The design is innovative because we will repurpose vehicle fuel injectors to spray the lubricating fluid and control them using a programmable logic controller(PLC).

Abstract

Our task is to redesign the Multicam3000 series CNC plasma cutting downdraft table and slag removal system.

When plasma cutters operate there are massive amounts of fumes and molten metal (slag) being thrown around. A downdraft table is meant to safely evacuate as much fumes from the work area as possible and to collect all the molten metal (slag) in one area for easy removal at a later time.

The current table that Multi-Cam uses has no issues but the design is over 10 years old. Project Vader is the pursuit to design/fabricate a downdraft table that can evacuate more fumes, provide a more efficient way to remove slag, and be more aesthetically pleasing.

Multicamcan then incorporate Project Vader in their current 3000 series CNC plasma cutting tables.

Abstract

Team Saturn was responsible for redesigning MultiCam's 15 year old rotary tool changer for their 5000 and 7000 series routers.

The major problems with the current design were inadequate protection of tools from debris when the CNC cuts material and the position of the motor being on topof the cover leaves little room for the dust collector on the spindle carriage.

We first started off by brainstorming possible design solutions. We narrowed the ideas down to 2 possible solutions and chose the most feasible option. From there we used SolidWorks simulations to modify our design so that it would meet the design criteria.

Completing this project was important to MulitCam because many failures occurred when debris got inside the tools and the spindle tried to grab them. This is not good for production because a CNC router is supposed to be as automated as possible.

Abstract

Currently there is no permanent solution for a height sensor on MULTICAM’s water-jet CNC machine.

The height sensor must be able to determine the standoff distance between the cutting tip and the material in which it is cutting. In addition all external components must be kept to a minimum and be easily replaceable.

The main issue tends to arise when cutting thin or cheaper metals. These tend to have built up stresses in themcausing the material to deform as it is being cut. Because of this the carbide tip runs the risk of impacting the material. Incorporating height and crash detection sensors are crucial to the design and development of this project.

A breakthrough with our design is the simplicity of the crash detection and its ability to be easily reset. This ensures continuous CNC operations with little downtime.

Introducing this design to MULTICAM’s water-jet will reduce production time and cost for the operator of this CNC.

Abstract

Increased orders mean increased shipments which can exhaust a normal human crew. Our design is to use a cobot, the UR-10 model, to effectively supplement the packing lines to increase productivity. The scope of the completed project will be rather large and, if successful, would spread to the rest of the Orora facilities. Our objective was to automate the cobot on a mobile modular track system, that through later software development, could sync to a cloud to retrieve order information, scan packaging slips, while pick and placing products from a rack to a moving conveyor belt.

The cart concept is a rolling plate inside a slotting tray, which sits upon casters for mobility. The cart portion is interlocking for modular needs and elevated to be a similar height as the conveyor belt. Additionally was designed a counting end-effector to process large number of small sheets of product, allowing product to be quickly organized.

Abstract

The University of North Texas Formula SAE team is competing in the 2018 Lincoln event as a sixth year team. After placing 13th overall in 2017, the team set its sights on making changes to the systems of the car for weight reduction, increased strength, and higher degree of accuracy in manufacturing. The senior design system focus is the suspension and chassis of the car. The goal of this design project is to redesign and fabricate the suspension and chassis of the UNT Formula SAE car. The suspension is being redesigned a better lightweight geometry. The new suspension design will allow the driver have more control of the steering of the car. The three key changes in the steering systems were; a one piece double U-Joint instead of two single U-Joints, splined steering shafts as opposed to SAE Grade 5 cross bolts, a needle thrust bearing for the steering column support, and a premium quick-release hub. These changes resulted in significant reductions in steering systems play. The interaction of a vehicle’s suspension and chassis is crucial for producing a car that is predictable and balance when pushed to its limits. The chassis design goal was reducing weight and increasing torsional rigidity while complimenting suspension changes.

Abstract

We are designing a solar canopy to cover most of theparking spaces on the top floor of the Highland Street Garage. The energy generated by the solar panels will help UNT save money on electricity, which will allow the canopy to pay for itself over time, and the canopy will contribute to UNT’s image as being environmentally friendly andsustainable.
Additionally, the canopy is expected to help UNT Transportation Services generate more revenue, since people are more likely to pay to park on the top floor of the garage if the parking spaces are covered.

Abstract

The primary focus of this study was to demonstrate how blade designs alter the power production of a wind turbine. The University Of North Texas (UNT) offers a wide array of engineering elective courses but most lack classroom models. For this reason, a wind turbine with four distinct blades was designed, engineered, and manufactured for the Alternative Energy (MEEN 4110) elective at UNT. The following four blade designs were chosen:

  • Short Design
  • Flat Blade
  • Increased Tip Radius
  • Wide Blade

Abstract

According to the U.S. Energy Information Administration, buildings make up 47.6% of the U.S Energy Consumption by sector. In order to reduce this large consumption, organizations have been put into place with the goal that every new building possess a net zero energy consumption by the year 2030. To achieve this goal energy modeling software is used in determining a building's necessary HVAC load. Energy models provide engineers an accurate real-life representation of the thermal properties within the building. From the Energy model data Engineers can size the mechanical system to be exactly what the building requires. HKS Architecture and the city of Arlington are in need of an HVAC system design for the new Arlington Performing Arts Center. To provide proper mechanical system drawings we utilized the energy model method to determine the necessary mechanical system and equipment sizing for the building. Thus reducing wasted energy from oversizing equipment and moving us one step closer to the 2030 goal. Alternative energy solutions, such as geothermal, do exist however there is a large limitations in professional engineers with experience in alternative energy solutions.

Abstract

The purpose of our project was to take a medieval device called the trebuchet, used as a siege weapon in the 13th century, and improve the design. We approached the problem by deviating from the traditional design and using a floating-arm trebuchet (FAT) design. This design maximizes the kinetic energy of the counter weight by allowing the counter weight to freefall straight down instead of the traditional elliptical path. This allows more energy to be transferred to the throwing arm and thus throwing the projectile further. Therefore, we were able to use our engineering education to improve an old medieval weapon system.

Abstract

Triumph’s current fastener installation process in aircraft skin panels is mostly done by a human. A mechanic is required to place a “stencil/template” depending on the size and shape of these panels on the aircraft skin and mark fastener positions for thousands of rivets. After this is completed, the fasteners will be grouped/boxed together based on hole sizes by drawing boxes, lines, or symbols that denote countersink or not, or a combination of all three of these processes to aid in the correct hole size to be drilled by a human or by specialized autorivet machines. Not only is this process time consuming, human error can play a role in the accuracy of these markings causing repair and in some cases scrap the expensive parts. The position markings placed on the panels cannot be off by more than .030 thousandths of an inch, roughly ½ the thickness of a penny to stay within required engineering tolerances.

In order to reduce manufacturing time, cost and potential scrap, our team was given the opportunity to automate the fastener marking system. Our team is utilizing a UR-10 COBOT, a 60 pound collaborative robot provided by Universal Robots. This allows the same mechanic who would normally spend twice the time marking fastener positions and hole sizes to perform other value-added work while the COBOT performs this repetitive marking task. By doing this, the fastener process on aircraft skin panels is much more efficient, repeatable, accurate and reduces scrap costs.

Abstract

Mechanics working for Triumph Aerospace are currently having to mark parts by hand which leaves room for human error. They are required to reference drawings every time they make a mark which is tedious and time consuming. Our solution is to create a collaborative robot easily programmed to stencil parts. We were tasked with creating an end effector for a collaborative robot to mark small parts. The cobot will move parts to a new work space using suction cups or grippers, reorient to mark the part with a sharpie end effector, and place parts back to the original box.

Our team designed and fabricated three separate end effectors for moving and marking parts, a work space for parts to be stabilized on while being marked, and a jig for the box of parts tosit. Implementing this cobot into Triumph Aerospace will reduce error in part markings which will save time and cost.

Abstract

We worked with UNT Facilities to design HVAC systems for the computer server rooms in Sage Hall and the University Services Building. Currently the computer server rooms for Sage Hall and the University Services Building are being served by HVAC systems that serve other parts of the building as well. Computer server rooms need to be served 24/7 as they are critical zones. Other areas in the buildings do not need to be served 24/7, so when they are unoccupied they are currently still being cooled and heated. This leads to extra energy and money being spent that could otherwise be conserved. If separate computer server room units were added then during unoccupied hours UNT could shut off the systems serving unoccupied spaces which would save energy and money. Through energy modeling we calculated the energy and cost savings that implementing separate computer server room units could provide. We then usedthe savings and the cost of adding new units to determine a payback well within the 7 year range.

Abstract

The problem that we were trying to solve is designing a shallow water skiff that would draft and run in less than 6-inches of water. Our solution to this problem is to implement a shallow water tunnel to help channel the water up to the prop without needing the prop to hang below the bottom of the hull. The tunnel allows us to achieve the 6-inch depth we were aiming for. Some of our design limitations are holding 2 people, weight, and the ability to haul 2 of these boats on a single trailer. This product was created using Solidworks to generate a 3D model, which then allowed us to have the company Johnson County Foam CNC the hull out of foam. One drawback of using foam was that the fiber glass resin would melt the foam, this meant we had to apply paper mache over the foam to protect it. After this we applied, fiberglass and sanded it down to create a smooth final product. This project is important for the fishing industry, as it provides a low-cost skiff with the ability to run in the shallow waters that bay fisherman would need.

Abstract

With the increasing use of composite materials in the aerospace industry, ZSUS tasked us with replacing a current metallic component of their seats with a redesigned lightweight composite, thereby making the seat more marketable to clients. We chose to modify the armrest core of their current Z-300 style seat, presently machined from 7075-T6 aluminum, with a high strength carbon fiber fabric and epoxy matrix to increase the structural strength and reduce weight.

In accordance with ZSUS safety standards and SAE aerospace standard AS8049A, armrests must be designed to meet handling and service load cases of 300lbf, 200lbf, and 150lb as well as fatigue loading without compromising seat safety.

After running FEA simulations our research shows the armrest core experiences high von misses stresses in the elbow region, which makes a complete carbon fiber piece unsuitable. Therefore, our project encompasses the bonding of anewly designed aluminum elbow with a carbon fiber sandwich structure to form an armrest core which is both lightweight and structurally sound. Using Solidworks, we redesigned the aluminum elbow with guide geometry that allows the carbon fiber beam-end to soundly bond to the aluminumguides. Further simulation analysis shows the bonded assembly will not fail and meets the listed load criteria.

Abstract

Our client Zodiac Seats US is one of the biggest suppliers of the aircraft seats to plane manufactures and airlines all over the world.

This project details the automation of commercial aircraft seat assembly intending to reduce time, labor cost, increase seat production, and ergonomics. The automation is achieved by using Universal Robots. The UR3 and UR10 are programmed to coordinate with each other to pick and place parts, and torque in the bolts. Molds are manufactured to hold the parts in place while the robots torque the bolts with the help of custom end effector.

The requirements of this project is not only the torque specifications, but also weight that robot can hold, the reach of the robot, space available at the manufacturing facility, and the budget. Our project meets all torque requirements and weight requirements, but has yet to be tested to see if it can reduce cost and time. With further iterations and testing cost and time reduction can be achieved.
