  • 1. 1. Looking back at your project now knowing better the expectations of the project whatwould you do differently? I would definitely have my group work on the inventor drawings first becauseeverything went smoothly except for the inventor drawings because there weretechnical errors at the last minute so I barely had time to fix them.2. What was the most valuable feedback from the engineers about your finalpresentation? The engineers actually didn’t say much at all. We gave our presentation and theysaid it was unique and good. Also they told us to keep up the good work.3. Did each person in the group have a role and a function? What was yours? Howcould you better set the roles and expectations for each group member? We all had our roles ant contributed to as much possible. Obviously Katie hadvacation so we couldn’t really collaborate much with her but I made the shoe whileSneha was working on the board. I glued on some pictures and I worked on inventordrawings and exploded views. The roles were laid out fine but what made it not workwas that Katie had vacation and that caused most of our problems.4. What was the most meaningful part of the assignment for you? How did the meaningof the design process change for you? The most meaningful part was when I felt very accomplished by makinghandmade shoes. It felt amazing. But on the way to making the shoes, I realized thatusing tire was too thick so I found car mats that were an excellent substitute.
  • 2. So we, as a group, are going to split the work amongst each other and we have the challenge ofhaving to send a potato chip through the postal service. But the chip is not allowed to break andit must be edible. We, the whole group, will try to collaborate through any method like Skype,calling, emailing, etc. And by these methods, we will have all steps looked over by all groupmembers.

  • 5. Aakash BalajiKatherine WongAlyssa HaselsteinerJordan Murphy Pringles Project ResearchThe U.S. postal service, also known as USPS, is an independent agency of the United Stateswhich delivers mail. We also discovered that the USPS went through a major change in 2010. Itinstalled a 5 day delivery and collection week instead of the former 6 day week; although thepost offices will still operate on Saturdays. The way the service works is customers will leavetheir packages with addresses and the proper amount of stamps in a postal service delivery boxor at an office. Also there will be a fee based on the flat rate box chosen. To clarify a flat rate boxis a box in which you put your mail and ship it for a pre determined price. Then the USPS willcheck the package for harmful substances and store them until the next delivery route to thataddress occurs. Next the mail will be handed off to a postman or woman and be delivered via thepostal van. The vans are long life vehicles and the USPS owns over a 100,000 of them. The vanwill be filled with as much mail as will fit appropriately and later taken out at the address by themailman or woman and given to the present party at the location. Here is a list of prices and sizesfor priority mail. We also found an online cost calculator on the USPS website that will calculatemailing prices for us.Priority Mail Flat Rate Envelope $4.95 12-1/2" x 9-1/2"Priority Mail Padded Flat Rate Envelope $4.95 12-1/2" x 9-1/2"

  • 7. http://www.usps.com/communications/five-daydelivery/ataglance.htmwww.usps.com/prices/priority-mail-prices.htmThe materials our primary idea consists of are peanut butter and a box that fits in the allottedbox/envelope and allows for at least an inch of space in between it and the chip in all directionswhen the chip is inside it. Peanut butter is a food paste made from dry roasted peanuts. The twomain categories of peanut butter are chunky and smooth. For the purposes of our project wefound that the smooth type was better suited because it is less dense and has no solids in it. Toadd on peanut butter is edible so it will not compromise the edibility of the chip. Our box will bemade of cardboard and be either a prism or cube because those are the shapes that fit best in theUSPS box. We also knew that both our materials are readily available. Another primary idea wehad involves the use of polyester pillow stuffing, copper wire, and cardboard to construct a cribfor the chips. Copper wire is ductile and sturdy so it can prevent compression. Polyester pillowstuffing is soft and firm so it can reduce strain on the chip. Polyester is a synthetic material that ismade from polyethylene terephthalate, which is essentially plastic. It is fibered, fluffed, flocked,or clustered for use as a pillow stuffing. The cardboard is used as a base for the wires to beplaced on. Cardboard is made mostly of wood and can be made of recycled paper thus it is earthfriendly. Copper is also an abundant resource. The materials for the second idea are alsocommon.
  • 8. http://www33.brinkster.com/iiiii/inventions/http://www.varioustypes.com/pillow_stuffingMoving on Pringles was invented by Alexander Liepa and Gene Wolfe invented the machine thatcooks them. The current owner of this brand is Proctor and Gamble. The shape of the chip isknown mathematically known as a hyperbolic paraboloid. They are shaped this way so they aremore tightly packaged. This shape is what helps protect the chips in the Pringles packaging in
  • 9. hich they are sold due to the chips cushioning each other. In addition their slender shape makesthem very fragile.http://www.google.com/patents?vid=3998975http://www.time.com/time/magazine/article/0,9171,947586,00.htmlCurrent viable solutions include the Proctor and Gamble packaging and numerous different kindsof chips containers. The majority of them will be able to transport chips but the chips will sustainmoderate damage. The two solutions that are most viable and used are the cylindrical plasticcontainer and the bag filled with air. The Pringles containers are shaped to snugly nestle thechips and protect them by almost completely immobilizing them. As mentioned before they dothis by using the shape of the chips to fit with each other. The other solution surrounds the chipswith air to block damage.
  • 10. Acceleration = Change in VelocityChange in velocity = force = mass x accelerationDistance = 9.8(acceleration due to gravity) x time squaredNext we calculated the different ways the chips could break. The first way we researched was therelation between velocity, such as when the package is dropped, and the amount of force exertedon the box. The force that primarily affects the object when it falls is gravity and the frictioncaused by the air. Also we found the type of break that occurs in a chip is called a fracture.Gravity is the force that is the result of the attraction of the Earth to other objects. The pull ofgravity increases as mass increases and so does the velocity. Velocity is distance divided by timeor how fast and object is going at a certain point in time. The absolute value of velocity is speed.As velocity increases so does the speed at which the package hits the ground. The faster
  • 11. something hits the ground the more damage it is likely to sustain. Also everything accelerates orincreases in velocity at approximately the same rate of 9.8 meter/second due to the constant pullof gravity. Now for example if our box fell for 10 seconds without any air resistance that meansour box would hit the ground at 98 meter per second and would have fallen from 539 meters.This is just a sample calculation to show how we can set up theoretical scenarios to predict thekind of damage the chip would sustain. Moving on the other factor that affects the terminalvelocity or the speed at which the object hits the ground is the mass. Mass is the measure of anobject’s resistance to being put in motion or, if moving, its resistance to being stopped. Thisother variable will make the object fall faster when heavier and fall slower when lighter becauseweight increases as mass increases. A factor that can help reduce terminal velocity is increasedsurface are on an object. Increased surface are on an object creates more friction with the air andslows the speed of impact.http://www.sv.vt.edu/classes/MSE2094_NoteBook/97ClassProj/exper/halahan/www/halahan.htmlwww.eeescience.utoledo.edu/Faculty/.../Physical.Chap01.gravity1.ppthttp://www.racemath.info/forcesandpressure/what_is_f=ma.htm
  • 12. We also explored other possible material for our project such as plastic wrap, bubble wrap, andpacking peanuts but we did not use these because we found peanut butter to be better. The mostcommonly used shrink wrap is a polyolefin. It is available in a variety of thicknesses, clarities,strengths and shrink ratios. A shrink film can be made to shrink in one direction (unidirectionalor mono-directional) or in both directions (bidirectional). Films are stretched when they arewarm to orient the molecules from their initial random pattern. Cooling the film sets the filmscharacteristics until it is reheated: this causes it to shrink back toward its initial dimensions. Allthese factors make plastic wrap seem like a good option but plastic wrap requires controlled heatand accuracy to use. This means if wrapped incorrectly our chip would be crushed by the wrapitself so we determined that it was not suited for this project. Next we saw that bubble wrap isdurable, lightweight, and helps fill voids in boxes to prevent movement. Another benefit itprovides is shock absorbance but we rejected this material because if it likely to compress thechip and break it during turbulent shipping. This is mainly due to the odd shape of the chip. Thebubble wrap does not mold to the chip’s unique ship like peanut butter does. Packing peanuts aremostly made from recycled polystyrene or starch and come in various shapes and sizes. Howeverthey are not easily accessible or cost efficient.http://www.usps.com/nationalpremieraccounts/bundlepreparationguidelines.htmhttp://www.theofficeguide.com/bubble-packaging/http://www.officedepot.com/a/browse/packing-materials/N=5+3972/;jsessionid=0000ypeDnmnpbWPOa224VYoXpip:13ddq0tfm
