Problem Statement<br />The USPS handles packages without care, and as a result, the contents of these packages are sometimes damaged. We need to find a way to reduce, absorb, and dispense the shock the packages are exposed to. <br />We will use the 12 step design process to evaluate, design, and develop a way to ship a Pringles chip from Fremd to Conant, or vice versa, without the chip breaking.<br />
Research<br />The USPS<br />The United States Postal Service (USPS) employs roughly 700,000 people who work to ensure that 213 billion pieces of mail are delivered to 146 million addresses each year. <br />It operates as a business, with total revenue in 2006 of $72.8 billion. It is governed by a board of governors made up of the postmaster general, the deputy postmaster general and nine governors who are appointed by the president. <br />
Research<br />Shipping and Processing<br /><ul><li>At the mail processing plant, machines separate mail by shape and size. They also orient the packages so their addresses are right-side up and facing the same direction.
A unique fluorescent bar code is imprinted on the back of each piece of mail. An optical scanner scans the address, and then a bar code representing the specific address is sprayed on the front of the envelope. </li></li></ul><li>Research<br />Pringles<br />Calculations<br />Pringles have only about 42% potato content, with the remainder being wheat starch and flours (potato, corn, and rice) mixed with vegetable oils and an emulsifier. They are baked.<br />Their consistent saddle shape is mathematically known as a hyperbolic paraboloid.<br />mass m= 1 kg <br />height of h = 5 m<br />velocity v = 9.899494936611665m/s. <br />kinetic energy = 49 J.<br />distance traveled after impact is d = .1 m <br />Average impact force = 490 Newtons.<br />
The Decision Matrix<br /><ul><li>Each Number value ranges on a scale of 1-5.
The meaning behind each number for each criteria may be different.
In the end, we concluded that a box solution would be the most viable.</li></li></ul><li>Testing our Box<br />That means that our box can take over 56 lbs. of weight upon itself without being crushed.<br /><ul><li>Each textbook weighs approximately 3.5 lbs. each
Both teams tested our designs and gathered data on how well the boxes stood the tests</li></li></ul><li>Video<br />
Our Final Prototype<br />Composed of : <br />1 cardboard box.<br />1 bag of cotton.<br />1 3rd Gen. IPod Nano case.<br />
