E&S CONSTRUCTION ENGINEERS

Description: Currently, I work as a mechanical engineer designing and constructing HVAC / plumbing systems for large commercial retail, primarily malls all over the U.S. As a project engineer, my daily tasks include generating 3D and 2D renderings of system designs using AutoCAD products. Below is a sample of the work that is not covered by propriety rights.

Figure 1 (E&S): Here is a 3D rendering of the exterior of one of the buildings I have worked on. I built this model from scratch using the construction documents I obtained from state building records in AutoCAD’s Revit.

Figure 2 (E&S): Building on Figure 1 (E&S), you can now see the interior of the building as well. Including office layout and the new mechanical system that will be added during the renovation. Everything is accurately placed within 1’ – 0”.

DOW CHEMICAL – CO-OP ENGINEERING DESIGN (PROJECT LEAD)

Figure 4 (E&S): For the final 3D rendering, here is an image of just the mechanics that were added during the renovation.

Figure 3 (E&S): With the exterior of the building removed, you can now see the amount of detail involved in this system.

Figure 1 (DOW – UD): Schematic layout of the Impreg line (SUBA1) used at the DOW Chemical manufacturing facility. The roller scraper portion caused maintenance crews problems for cleaning due to the location and large number of steps necessary to clean the blade whenever a new polymer was introduced.

Description: As a senior at the University of Delaware, the final year curriculum intended to expose us to a wide range of real world problems in order to prepare us for post graduation exercises. Our main exposure came when the University of Delaware partnered us with companies needing solutions for real-life engineering problems. In a group of 5, I was partnered with DOW Chemical to solve a problem on their manufacturing line during the production of polishing pads used on large semi conductors.

Project Scope: To modify the Impreg Line (SUBA1) for easier and safer maintenance of the Teflon roller scraper used in the removal of excess polymer left over from the wicking process. While also considering material containment and product consistency. The modification should be designed, prototyped, and tested. Once DOW engineers sign off on the design, construction documents need to be detailed and presented.

Figure 3 (DOW – UD): After many alterations and hours of working with DOW engineers, we came up with this final design concept, the Mark II. We kept with the idea of using two lightweight and low friction materials for the sliding system. While also adding a polymer collection system was also added to collect and store the excess polymer that was taken off by the Teflon scraper until it can be safely removed.

Figure 2 (DOW – UD): Our original concept generated in Solidworks, Mark I. The key to this design was to have the scraper portion slide out using a combination of two very low friction materials. This was choosen over a typical ball bearing slider system due to the potential risk of rusting that could occur with the polymer in use.

SWIM FIN – ENGINEERING DESIGN (PROJECT LEAD)

Description:As a junior engineer at the University of Delaware, the curriculums emphasis that year was to combine our engineering knowledge with real world design issues. Our professors asked us to design, develop, build and test a swim device that could increase a swimmers efficiency. The kicker was that it had to be completely human powered. Below you will see the results of my work that year…

Figure 4 (DOW – UD): A working prototype of our Mark II’s design solution for the Teflon scrapper slider. This prototype was built to demonstrate our concept to DOW and was used for testing / design analysis.

Figure 5 (DOW – UD): Final presentations required a presentation board highlighting features of our design project.

PROJECT ACCOMPLISHMENTS: Working in a real world environment. Taking the design from concept to actual implementation in the

manufacturing line. Managed a group of 5 peers effectively, while working on a manufacturing

line that produces more then $50,000 of profit per month.

Figure 1 (Swim Fin): Beginning sketches and calculations of the original swim fin design. The main take away from this is the utilization of cables and springs; the idea was to attempt to capture all forms of potential and kinetic energy.

Figure 2 (Swim Fin): Mark I is the original design and 3D rendering of the swim fin using Solidworks.

Figure 3 (Swim Fin): Mark II, after reviewing Mark I’s overall design and calculated assumptions, I went back to drawing board in hopes of improving. The main difference is the decrease in the overall fin surface area because Mark I’s large fin required too much force by the swimmer to propel themselves forward.

Figure 4 (Swim Fin): Mark III, is the final accepted concept of the swim fin design. This design was generated in SolidWorks, which would then be used to build a full scale prototype.

ALTERNATIVE TRANSPORTATION DURING WINTER MONTHS

Heated Side Walks

Description: During my sophomore year engineering design course, I was tasked with developing several unique concepts for traveling to and from class in the harsh winter months. This exercise was used to introduce innovative design and problem solving into our engineering questions.

Project Metrics:

Figure 5 (Swim Fin): A Finite Element Analysis (FEA) was performed to test the deflection done on the Mark III’s swim fin at peak intervals during forward movement. Obviously you will see the main deflection occurs at the tails tips due to the structural design.

Figure 6 AB (Swim Fin): A completed full-scale prototype of the Mark III’s concept. The prototype was then tested in the water to see if the results matched the assumptions.

PROJECT ACCOMPLISHMENTS: Took a design from concept to working prototype. Won the most innovative design award presented by the University of

Delaware Mechanical Engineering Department.

Underground Tunnels

Studded Tires

INDEPENDENT DESIGNS

SWIM FIN FOR PARAPLEGIC INDIVIDUALS

Description: Even prior to earning my degree in mechanical engineering, my passion has always in the design and development of consumer products. So much so, that whenever I find time outside of work or coaching soccer, I enjoy researching and designing my own products. Below are a few concepts I’m excited about and that I feel have potential in the marketplace.

This idea is a continuation from the swim fin I designed my junior year at the University of Delaware. However, the difference is that this device mimics the swimming motion of a manta ray to generate motion using only the upper body. By utilizing the upper body’s muscles, this design allows those who can’t operate their legs normally, or have difficulty, to now have a chance to move more efficiently through the water and even scuba dive.

Figure 3 (AT): Design in SolidWorks, these custom-made bicycle tires will allow students to more safely travel to class in the dangerous winter months.

Figure 1 (AT): Designed in SolidWorks, these heated sidewalks use electrical heat tracing or steamed heat vents to melt the snow. Allowing for cost cutting on manual snow

Figure 2 (AT): Designed in SolidWorks, the underground tunnels would provide students with safe travel to and from class in a conditioned environment. With students and teachers not using the roads or sidewalks, manual snow removal costs could be reduced.

ATHLETIC WATER BOTTLE (PRE/INTRA/POST MIXING)

This water bottle was designed to allow athletes to apply (up to 3) workout supplements to their drinks with just the turn of a handle. The point being that most “bodybuilding” water bottles have separate compartments that can be removed and then have the supplements poured into the bottle. This can be a hassle, so I’ve designed a bottle that allows for direct feed of the supplement into the bottle. The water bottle below has three separate compartments that are attached to the bottle and with the turn of a handle immediately supply supplements to your drink. This result in a 4-step process becoming a 1-step process.

REMOVEABLE LAX “HEAD”

This 2 piece lacrosse head allows for easy “pocket” netting transfer. The idea behind this is that in bad weather, the pocket netting absorbs water/mud quickly, which can adversely affect a player’s performance. The extra weight from the water in the netting can be a big factor by slowing head speed and whether or not you score a goal. But with this design, it allows for the user to exchange netting quickly and easily during the game. Which means the athlete can replace heavily saturated netting, with dry light weight netting, thereby maintaining optimal play characteristics of the lacrosse stick. Some additional benefits include changing a players “pocket” from offensive to defensive properties, such as changing a pockets release time and hold on a ball.

SOCCER SHOE “SOCK”

The soccer shoe “sock” is just that, it allows for an external layer to be placed around the exterior of a cleat. The concept is based off the idea that when an individual is fit for a cleat they aren’t necessarily thinking about if the thermal layer in the cleat will keep their feet warm in cold conditions. So, for many athletes that play in cold climates, they just wear an extra sock to keep warm. That extra sock has subtle negative affects on the cleat. Such as warping the leather around the opening and in some severe cases the cleat can break apart completely due to the force being exterted from the extra layer of insulation. Instead of forcing an extra insulation layer in your shoe when it’s cold out, you can place a layer on the outside of your shoe. Having the layer outside allows a player to then have a great fit in their cleat in all conditions. Some added benefits include cheap/customizable socks that can change a player’s look. This can also be used for brand recognition since it is placed on the outside of the
