Deister Machine Gear Cover
Deister Machine Inc. is an international aggregate screening and handling equipment manufacturer.
Deister approached us for help with the redesign of a gear cover for an aggregate shaker screen. Deister needed to lower the weight and cost of the gear cover. The design had to have infinite fatigue life, withstand 8Gs at 800 RPMs, and could not be cast.
The team researched several concepts, set the product specifications, designed and analyzed the gear cover utilizing SolidWorks 3D modeling software and built the prototype. The team identified a solution that met and in some cases even exceeded Deister′s requirements.
Dometic Industries High Capacity Ice Maker
The time has come for a new implementation of ice making. Dometic presented the idea to engineer innovative ice–making concepts.
Dometic Industries is a worldwide supplier of high–quality and innovative products for the RV and Marine industries. The current ice–making process, in which ice is made by using only the absorption refrigeration process, is inefficient, producing only 3 to 4 pounds of ice in 24 hours, the current RV refrigerating ice makers do not supply travelers with the amount of ice they need daily.
The team researched various concepts, set specifications, performance designs and analysis using SolidWorks 3D modeling and analysis software to redesign the ice maker concept. Prototypers were built to prove out the design. The redesign of the ice maker is projected to allow consumers to produce approximately 20 to 28 pounds of ice in refrigerator and close to 30 pounds in a stand–alone ice maker drawer in a 24 hour period, which raises the productivity level of ice making approximately by 15 percent. The innovative ice makers will be placed in the current Dometic commercial vehicles. The drawer will allow an alternative way to retrieve ice and is projected to be placed underneath the counter in a Marine Cruiser, RV and ultimately households.
Pokagon State Park LEED Certified Amphitheater
Pokagon State Park recently acquired 200 acres of land northeast of the main park in Angola, Ind.
This site included remains of a once functional amphitheater, including a concrete stage and seating area. In an effort to save as many existing structures as possible and create a new area for Pokagon to hold outdoor events, the amphitheater site was rehabilitated. The project incorporated both structural and environmental design aspects.
The design focused on a new steel structure, rehabilitation of all existing concrete, an updated runoff collection system, and a solar panel array for on–site electricity generation. The amphitheater site was rehabilitated using LEED certification guidelines, producing an environmentally friendly project.
"RaFT," the Radio–Frequency Tracker
Locating a radio beacon is a problem encountered in several endeavors, including science and the military. Whether tracking wild animals or friendly soldiers, there are two different approaches: GPS–based positioning and radio–tracking.
This project offered a small transmitter or beacon that can be carried by a person, a seeker′s antenna array which can be handheld or mounted in a frame, and a computer interface to indicate the beacon′s location. The team provided mapping as well as a simple direction and range estimate.
Metal Technologies Inc. in Auburn, Ind., uses spectrometers as a part of its quality assurance process to ensure that the iron parts coming off the line meet the chemical composition requirements specified by its customer. These spectrometers are regularly calibrated using certified iron blocks with a known chemical composition.
We developed a repeatable process that creates iron blocks with a predictable chemical composition. The process for creating these blocks consists of melting scrap iron, supplied by Metal Technologies, and pouring the molten iron into a mold attached to a heat exchanger.
The cooled test blocks were analyzed to ensure correct chemistry, composition, and microstructure by both the group and Metal Technologies. Various types of molds and heat exchangers were investigated and tested. A national market exists for these, and commercialization will be investigated.
Xylene Purification from an Acrylic Resin Production System
Anderson Development Company of Adrian, Mich., produces acrylic resin used for powder coating applications. A xylene solvent is used in the manufacturing of this resin. The solvent is recovered from the process, but most of the recovered solvent is contaminated by other chemical compounds. This project involved the conceptual design of a xylene purification process.
The design processed the contaminated xylene solvent and upgraded it to meet the specifications of market grade xylene. Different design options to perform were investigated and specified. Preliminary equipment specifications and cost estimation were performed on each proposed design option. A rate of return and the advantages and disadvantages of each were considered along with a safety and environmental analysis.
