The Stretch Test is a unique apparatus designed to simultaneously stretch elastic fabric and read the quantity of light passing through it. Modern athletic wear has become a staple in women’s fashion however it often becomes transparent as the fibers are stretched. The Stretch Test makes it possible to test different fabric compositions for opacity and assign a rating to compare one’s transparency to another. Unlike anything currently on the market, the rigid steel structure provides quantifiable and repeatable testing capabilities to rate any elastic fabric. As a result, The Stretch Test is an effective tool for clothing and textile manufactures around the world.
Have you ever paid hundreds of dollars on a pair of ski boots, only to find out that they feel terrible when you ski in them? With Das Boot’s innovative True Boot, this problem will soon become a thing of the past! For use in ski shops, the True Boot is a device that allows users to test out ski boots in the shop before making a decision on which pair to purchase. Adults can put on a pair of ski boots, step onto the True Boot, and in a single motion get a sense of how the boots will feel on the slopes. Developed by a team of five mechanical engineers from the University of Nevada, Reno, the True Boot will be be completed in May of 2016 and introduce a new way for skiers to tryout their ski boots while off the mountain.
Water Works has created a water tunnel for the mechanical engineering department. The faculty members and students may utilize the device to study objects that undergo laminar flow of water. The water tunnel is designed to be highly adaptable, unlike the tunnels available on the market today. The flow becomes laminar after it flows out of the reservoir tank and through a honeycomb specially designed for the water tunnel. The tunnel’s flow of water is highly responsive due to a speed controller and can reach water speeds of up to 1 meter per second. The size of the test area can be varied according to the tester by simply sliding a hatch to physically limit the width of the tunnel. To make it easily maneuverable for the faculty members and students, the water tunnel is mounted on a cart-like apparatus.
In the Reno Air Races, pilots, engineers, and aviation enthusiasts work on building the fastest experimental aircraft. An effective way to increase an aircraft’s top speed is by improving aerodynamics. This project focused improving the aerodynamics on a Thunder Mustang, or a ¾ scale P-51 Mustang. There were two main points on the aircraft causing parasitic drag: the cockpit and the radiator scoop. DR3D-M focused on redesigning the radiator scoop.
Mad Injections’ goal is to design and manufacture steel and 3D printed molds that will be used in future courses at the University of Nevada, Reno. The design of the mold’s cavities will create a product that will be used by the Mechanical Engineering department here at UNR to pique student’s interest in the subject of injection molding. Instructors will be able to use the steel mold to mass produce parts made out of injected & molded plastics that range from acrylonitrile butadiene styrene (ABS), polyethylene, and/or polypropylene. These parts will be put together by students and will also give them hands-on experience in injection molding. For parts needed to be made in only a limited quantity, 3D printed molds will be able to replicate more intricate and unique pieces for a cheaper investment. Not many engineering students know the process of injection molding, which is why it is important for Mad Injections to design and manufacture molds that will create an intriguing product that will excite and engage students into learning about the subject.
Individuals with severe physical and mental disabilities often lack refined gross motor skills, which include broad arm and leg movements. At Marvin Picollo School, a special education school in Reno, bowling is an activity that is used to practice gross motor skills. Quick transitions during activities are important in special education classes because distractions are a common issue for special education students. Currently, Buddy Lowe, the adaptive PE teacher at Picollo School and the sponsor for this project, manually resets the bowling pins for his students. A primary focus of this project will be to minimize the time between students’ turns. Team Turkey is designing a portable bowling pin resetter that automatically resets the pins. The instructor can then spend more time with the students, and students can take more turns within their allotted PE class time.
The Bootie Bunch is creating the first purely mechanical automatic shoe cover remover that removes polypropylene shoe covers in an effective, efficient, and safe way. Polypropylene shoe covers are made with durable plastic, so the final device operates on a mechanical advantage derived from the gear-spring mechanism located in the interior of the device. Furthermore, the design provides a handle for balance and allows users to store the shoe covers for a quick disposal. The design will be constructed from lightweight metal parts in order to resist user stepping forces, while still maintaining an easy weight for transportation purposes. Current shoe cover removers function with a vacuum extraction system, yet this is inefficient for porous shoe covers, or shoe covers with tiny holes, because the remover cannot take them off. Our device does not use electricity, and it can remove a wide range of shoe covers, thus making it adaptable for any environment and setting.
Shoe Inn Rebooted is a team dedicated to overhaul the, completely manual, manufacturing process of building custom shoe cover cartridges for a local company, Shoe Inn. These shoe cover cartridges are designed to fit into a custom shoe cover dispenser, which is used in many industries, where cleanliness is a necessity. The team has come up with an assembly line design that will greatly increase the productivity of the manufacturing of the shoe covers. The end goal of the manufacturing process is to cut the manufacturing time of a single shoe cover cartridge by at least 50%. This process will decrease the price of the manufacturing which should have a trickle-down effect to the customers.
Athletic Purpose: The Backcountry Ski Power Meter is a preliminary product that will introduce the use of tracking power values into the winter sport of backcountry skiing. The application of power in sports has been primarily used in the sport of cycling, and can provide the user with multiple values to gage their performance. The professional and competitive athlete can use power output to fine tune training levels and zones, helping further their athletic ability in the sport. The recreational athlete can simultaneously use the power meter for the same reason as the competitive and professional athlete, and can also track calorie expenditure and general fitness. Having a preliminary introduction of power into skiing will provide beneficial feedback from customers and users alike with different uses to further research and develop.
Winter snow sports and outdoor recreation are becoming increasingly popular, and there is a strong need for safety gear that will keep winter enthusiasts safe in unsure snow conditions. Every year, hundreds of people die from avalanches and snow suffocation because of a lack of information and little use of safety equipment. The current safety standard for backcountry winter sports is to never travel alone and to wait for fresh snow to settle; however, many tend to ignore the safety standard because they enjoy the solitude of backcountry recreation. And because of the dangers associated with backcountry sporting, there exists a large demand for a reliable and cost effective device that will reduce the danger of traveling in these areas by helping winter sportspeople survive in a snow slide. A solution to this problem is to design an alternative avalanche airbag that is internally mechanical, reusable with no extra cost, inexpensive, and lightweight that will keep prevent users from being buried under avalanches.
Team Dyno Punch was approached by The Nevada Karate Association which needs a mobile device that can record impact energy. The Nevada Karate Association moved to a new building which is a shared complex and cannot leave anything in the building after their class. Therefore, their striking surfaces, punching bags and striking posts, cannot be permanently fixed in the classroom. The Nevada Karate Association does have special striking surfaces that measured impact forces with 27% error which they used to manually track training progress but they came to us to create something more accurate and user friendly. The Nevada Karate Association needs a device that will record and trend an individual’s impact energy with 5% error. The new device cannot be anchored to the wall or floor and must be mobile enough for one person to move it. Team Dyno Punch aims to create an easily portable device that will automatically track and trend multiple users strike information.
With the rising use of 3d printers, whether it is for rapid prototyping or hobbyist creations, there is an ever-increasing demand for lower cost manufacturing materials. Most entry level 3d printers are extrusion type printers; these printers work by feeding a plastic filament, not unlike weed trimmer cord, into a heated nozzle and precisely laying the melted plastic to form a 3-dimensional object. The Filamaster extruder will allow the user to purchase cheap, thermoplastic pellets, and extrude their own filament for a much cheaper price than buying the filament in spools. The Filamaster Shredder will be able to recycle old prints, as well as other plastics such as old remote controls into new filament to be printed with.
Most hand powered tricycles have cumbersome controls that are difficult to operate and visually displeasing. The objective of Trike-Me was to design a sleek and functional hand powered tricycle. The sponsor requested a hand powered tricycle with no controls (shifting, braking, and turning) on the hand pedals, one wheel in the front, and rear steering. To satisfy the demands, the group designed a tricycle that is hand powered with foot controlled steering. The tricycle’s design also utilizes a chain system with a 9-speed internal geared hub. The hub is a low maintenance alternative to conventional systems that offers a similar range of gears while preserving the simplistic chain line. The braking of the tricycle is accomplished with the use of a two brake system. The brake levers are positioned on the side of the rider which allows for powerful braking in an ergonomic location. The multiple systems of the tricycle function in unison to produce a successful design.
In the solar power industry, panels often become dirty over time due to rain, dust collection, industrial pollution, bird droppings, and more. Currently, most solar panel providers rely on inefficient methods for cleaning solar panels such as rainwater or hands-on methods with brushes or squeegees. An alternative method for cleaning these panels that improves their efficiency and removes unnecessary labor costs would be economically beneficial. Mech Wash is determined to ensure solar panels maintain efficiency by providing an affordable cleaning device that sweeps dust off modules without using water or chemicals. The device will utilize a brush to clean panels while being able to move autonomously. One of the convenient features of the device is its ability to attach onto installed solar panels. Mech Wash intends to provide a low cost, and low maintenance device.
Sail Yeaaah is an industry sponsored team by the company North Sails. The purpose of our project is to create a custom abrasion tester to help North Sails develop new protective coatings for their ultralight racing sails. These racing sails are used in prestigious events such as America’s Cup, which is an event in which six teams represent their country to sail in several races. In order to create coatings that are lighter but protective enough, North Sails needs a custom abrasion tester to meet the needs of their specific samples. Once North Sails has an accurate, dependable, and repeatable testing machine, the company can compare different coatings that are resistant enough to withstand the conditions of the race while being lighter, which translates to speed. Sail Yeaaah’s goal is to create a professional bond with North Sails that ties education with application.
The most substantial problem with the current design of bicycles is that they are highly inefficient, when used in urban settings. The kinetic energy that the bicycle receives and stores as momentum, is wasted away every time the rider needs to come to a stop. This is extremely frustrating when stopping frequently. To address this problem, the Cycle-Paths team is developing a Kinetic Energy Recovery System (K.E.R.S.) for bicycles. The K.E.R.S will use regenerative braking to store energy that can be later used to propell the bike back up to speed.The only regenerative braking bicycles that are currently on the market use electric systems that are unreasonably overpriced and extremely inefficiency. The Cycle-Paths are designing a regenerative braking system that uses compressed air instead of electricity; it will double the amount energy recovered and and cut the price in half. The Cycle-Paths’ K.E.R.S will make cycling more convenient, and a more enjoyable option for commuting.
Nanotechnology is a new and exciting field that has opened many doors when it comes to science and engineering. While the term “nanotechnology” covers a broad spectrum, it is commonly applied to chemistry, biology and material science. The most important aspect of our project is to create an exciting visual reaction when nanoparticles are exposed to a certain range of near infrared light. More research into visually changing reactions with nanoshells is the next step in developing a working demonstration kit. The end goal is to illustrate that nanoparticles are not simply a work in progress, but rather a working technology that has endless possibilities. Looking at our project, we will be demonstrating the many uses of nanotechnology that include heat transfer, light refraction, and drug delivery.
In many industries, fast application of personal protective equipment is necessary to perform successful work; however, some equipment can be difficult to apply quickly. The application of disposable gloves can be incredibly time consuming, especially under the condition of wet hands. Because of this difficulty, it is common to see many workers in large scale facilities become bottlenecked at prepping stations. This congestion can cause a loss in productivity every day. The manual procedure of applying gloves has the potential for gloves to tear, causing excessive waste and additional costs. Applying gloves manually also has the potential of contaminants being on the surface of the gloves, creating an unsafe environment. Team Glovetrotters aims to create a disposable glove dispenser that would alleviate the congestion of workers, significantly lower the amount of time lost, prevent gloves from tearing, as well as reduce the contaminants on the outside of the gloves.
Smooth Sailing: Sails are put through immense forces during their lifetime, which fatigues and shrinks the material, rendering them useless. The fatigue machine used today fatigues the sail material, although it does not adequately simulate the abrupt and strong stresses that a sail is put through. North Sails, one of the largest sail manufacturers in the world, has reached out to Team Smooth Sailing to develop a dynamic fatigue machine that can artificially simulate the instantaneous shock loading a sail experiences. The goal is to design a way to reliably and repeatedly fatigue sail samples under shock loading conditions. North Sails will then analyze the sails after they have been fatigued to determine how the fatigue affects the ultimate strength. With the given feedback, North Sails can then make appropriate measures to change cost, lifetime, and efficiency of the sails. Having measurable data on the fatigue of their sails will also provide proof of integrity of the sails for North Sails’ customers, creating a better business assurance between the two.
FRW is a senior design project at the University of Nevada, Reno dedicated to redefining the process of friction stir welding. The goal of this project is to make a clean and efficient material joining process accessible to small operations. This project will bring new opportunities to schools and small machine shops, allowing them to join pieces of aluminum easier than ever before. Friction stir welding uses rotary friction to join two separate pieces of metal together. This is done by bringing the metals to a plastic deformation stage and not melting the metals. A customized friction stir welding tool is used to make the seam. It is spun with a 20 HP CNC machine. By advancing the tool along the seam and applying a vertical force as the tool is rotating the whole process can take place. Most of today’s friction welding machines are very large and costly. With Team FRW’s prototype the size and cost will decrease dramatically.
Team Ascent formed around the idea of building an Unmanned Aerial Vehicle (UAV) capable of two flight modes: traditional, fixed-wing forward flight and Vertical Take-Off and Landing (VTOL). This allows for efficient, long-range operation in fixed-wing mode, and highly maneuverable, hovering flight in VTOL mode. Ascent chose the name Alatron for their UAV as a nod to both aeronautics and robotics. The bimodal nature of Alatron is a solution to the battery life limitations of conventional UAVs. Its versatility and efficiency makes it suitable for filling roles in a variety of applications, such as surveying, search and rescue, and humanitarian. With the backing of their sponsor, the Nevada Advanced Autonomous Systems Innovation Center (NAASIC), and their team mentor, Dr. Logan Yliniemi, Ascent is exploring the use of multirotor systems, carbon fiber body and wing construction, and various airfoil geometries to optimize the design.
Team 23’s objective is to create a device that will make the process of applying a ski skin easier than the traditional method. A ski skin is a latex layer that is put onto a ski to ascend a mountain for backcountry skiing. The traditional method of applying a ski skin is to take off one’s ski, dry the bottom ski off, carefully apply the ski skin, apply extra force to ensure that the ski skin will stick, and put one’s ski back on. This process takes on average five minutes for an average leveled backcountry skier. Team 23’s goal is to allow a backcountry skier to apply their ski skin without the removal of their skis and do so in less time than the traditional method. These goals mean the device would have to dry the ski before the application of the ski skin, guiding the skin onto the ski, and allowing for extra force to ensure the ski skin is on correctly.
The guitarist strikes the last chord in the solo, letting the note linger for a moment before the crowd erupts in applause. This was their first show, and the band was thrilled to soak in the cheers. Exhausted but satisfied, the band smiles as the crowd slowly makes their way out of the venue. However, before long a feeling of dread creeps over them. As they tear their eyes away from the tides of people, the band comes face to face with a horrific mess of equipment. The sound cables had become grimy and tangled, and the band would have to spend hours cleaning and organizing them. Suddenly, a lone fan walks up to the stage with a strange machine. Without saying a word, the fan presses a button and all the cables are cleaned and coiled before the band’s eyes. This is the idea behind the Cable Combatter, a device that automates the cleaning and organizing of production cables, and Rebel Engineering’s goal is to make this story a reality.
Flocking and schooling are natural phenomena in which individual birds or fish (respectively) will move together in a coordinated group. These organisms create unique flow fields within their respective fluid mediums. The fluid dynamics of these flow fields are of interest to Dr. Hassan Masoud, one of the faculty of Mechanical Engineering Department at the University of Nevada, Reno. He is currently conducting research to determine if birds behave this way to minimize energy expenditure, or if they self-organize to maintain a hydrodynamically stable relationship with their neighbors. Team Ornithopter will be constructing a device, the Flapping Wing Simulator, to simulate these conditions mechanically. This device will offer qualitative data in the form of flow field visualization, and quantitative data in the form of the forces experienced by each fin in the flow field. This design is an improved version of a similar apparatus constructed by the Courant Institute of Applied Mathematics at New York University.
For the outdoor enthusiast who rides a motorcycle, quad, or snowmobile, there are a number of pickup truck ramp options on the market. Although they serve some function with regards to loading and unloading, many of these ramps can be very unsafe because they don’t physically attach to the truck. Those that do attach to the tailgate are generally bulky and cumbersome to haul and store. Ramp NV has found the need for a ramp system that not only allows riders to conveniently load and unload their power sports equipment, but also gives them peace of mind knowing their ramp won’t tip over during the process. Even better, when not in use, the ramp will be very space efficient. With state-of-the-art safety features, the Ramp-It-Up system will be built to last, utilizing the best possible manufacturing processes and materials.
Cryptocurrencies and the underpinning blockchain technology are set to disrupt global financial markets, and person to person connectivity in a way that has not been seen since the formation of the internet. Team Fratcoin seeks to capitalize on this emerging market by developing secondary service products based around bitcoin, and person to person payment networks. The first such product in development is the formation of a coin sorter and exchange service that will allow consumers to exchange their physical spare change into digital coins allowing for a simple way for the masses to become involved in cryptocurrencies while minimizing the risk associated with the free market volatility of bitcoin as it matures as an established market. By providing an easy to use way to integrate bitcoin into daily use the goals of spreading bitcoin into the local market will allow for a wider and more developed global financial market.
