Design & 3D ModelingFunctionality and Design RequirementsThe hookah is a water pipe designed for smoking a tobacco product called “Shisha” which is a gooey and often flavored form of tobacco. The purpose of the hookah is to create a pleasant smoking experience that cools the smoke that is produced, and delivers the smoke to the user in an easy way. Both of these things are accomplished. With the use of direct injection of smoke into water held at the base, the smoke is cooled. By attaching a hose to the hookah, the smoke is delivered easily, and at a reasonable distance away from the apparatus, to the user. Hookahs are becoming increasingly popular amongst the college community, and remain very popular in Middle Eastern culture. There are a few design requirements associated with designing and ultimately producing a hookah. Because the hookah is subjected to great heat from charcoals and smoke, the entirety of the piece must have some level of eat resistive qualities. The charcoals come in direct contact with the bowl at the top of the hookah, and as a result, the bowl was designed to be made of ceramic, a fairly heat resistive material. Additionally, all parts of the body, besides the glass base, are composed of heat resistive metals. Of these metallic parts, all are made of stainless steel, excluding the charcoal tray which is made of an aluminum alloy. The tray is the only part not made of stainless steel because it does not have to support the weight of any part of the hookah.Another requirement of the design of the hookah is that all parts must have an air tight fit. If this were not the case, the hookah would have air leaks and would not function correctly. To create air tight connections between the parts, I inserted rubber spacers and air seals. These parts are made of rubber so that they can easily conform to the shapes of the parts around it, providing the most air tight seal possible. Where there were rubber pieces between parts, the parts were connected by screwing into each other. Though not perfect, having the parts screw into each other will create enough of an air tight seal to make the hookah function well.

The top opening of the bowl allows enough space for tobacco to be placed inside of it and for the coals to rest on top of it. The bowl is tapered so it can be inserted into the head base for a tight fit. A small hole at the bottom allows for smoke to travel through the bowl to the rest of the pipe and prevents tobacco from falling through into the rest of the pipe. The bowl is made of porcelain because it is a material that is good for resisting heat. The bowl will be subjected to great heat from the coals.The rubber spacer will go over the tapered end of the bowl and into the head base. The spacer is shaped the same as the tapered end of the bowl and the head base to ensure a tight seal between the two other pieces. It also prevents damage to the two other pieces surrounding it because it will prevent them from touching each other. The spacer is made of rubber so that it can stretch to fit the tapered end of the bowl and compress for a tight fit inside of the head base. There is also a small hole in the bottom to allow smoke to flow to the rest of the pipe.The head base will hold the bowl and the rubber spacer, and will screw into the connector piece. The head base screws into the connector piece to ensure an air tight seal so that no smoke escapes out of the pipe. The head base is made of stainless steel because of its heat resistive properties and because of the strength of material; this piece supports the bowl and should be sturdy.The charcoal tray will go in between the head base and the connector piece. The charcoal tray is used as a place to put the charcoals when the user does not want to heat the tobacco anymore. The tray is made of aluminum alloy because of its heat resistive properties, but is not made of stainless steel because it is not an element of the assembly that supports weight.The connector piece is a decorative piece of the assembly which adds some length to the assembly. It screws into the top of the center piece and into the bottom of the head base, creating an air tight seal for a clean transportation of smoke through the pipe. The connector piece is made of stainless steel because of its heat resistive properties and because the part has to support weight.The center piece is another decorative piece of the assembly which adds length to the assembly, and sports the Saváge logo (fictional brand). The center piece is sandwiched by two connector pieces, where all three parts screw into each other to ensure an air tight seal. The center piece is made of stainless because of its heat resistive properties and because it must support weight. Another connector piece is below the center piece. The connector piece is described above.The lower connector pipe in turn screws into the bottom of the connector piece. The pipe sandwiches the bottom middle piece to the connector piece and is allows the smoke to flow into the water. The pipe is made of stainless steel because of its heat resistive properties, and because it will be exposed to water frequently. The hookah base holds the water that makes the hookah a water pipe. This is also used as a decorative piece. The base is made of thick glass so that it is durable (as far as glass goes) and so that smoke can be seen traveling into the pipe. The rubber air seal creates an air tight seal between the hookah base and the bottom middle piece. This is necessary because once smoke travels from the lower connector pipe into the water, the smoke then travels back up into the bottom middle piece. If there were to be an air leak between the base and the bottom middle piece, the hookah would not be functional. The air seal is made of rubber because rubber is flexible and can deform its shape to create a tight seal to the two parts it comes into contact with.The bottom middle piece directs smoke out of the hookah and into the hose. It has an opening and connector that allows the hose to be inserted into this piece. The bottom middle piece is made of stainless steel because of its heat resistive properties and because it needs to be able to supports weight.The hookah hose has three main parts to it: the rubber connector, the polyurethane hose, and the oak mouth piece. The connector piece is inserted into the bottom middle piece, and is made of rubber so that there is an air tight seal between the bottom middle and the hose. The hose is made of polyurethane because it is a flexible, durable, and washable plastic and typical to hookah hoses. The hose is also given significant length so that the users do not need to be right next to the hookah in order to use it. The mouth piece is made of oak as a decorative element and for taste purposes. The mouth piece is tapered at one end so that the user can comfortably put their mouth around it, and the handle of the mouth piece has some length to it for ergonomic purposes.

This can be attributed to a lighter product, reducing fuel costs of transportation, and a simpler manufacturing process, possibly reducing machine run time. The downside to a polyurethane base is that it could not support the rest of the assembly as it currently stands. The hookah would need to be remade of different material. Though more environmentally friendly, this product would be less desirable to consumers because of the current stigma of a larger, heavier piece being a better one.Part Manufacturing- Injection molding3063240107315000-309880107251500CAD Theory QuestionsDid you find it hard to create the parts?Some parts were more difficult than others. Specifically, there were parts that had to fit inside other parts, and the pieces that needed to line up correctly were splines, which were somewhat difficult to dimension. In the beginning it was difficult figuring out how everything was supposed to fit together, but as I progressed through the design process, I started getting the hang of it and I figured out some shortcuts to cut down on design time.Did you find it hard to create mating conditions? Which ones? Why?In the assembly, it was difficult mating the rubber air seal to the hookah base, the bottom middle piece to the hookah base, the rubber spacer to the head base, and the ceramic bowl to the rubber spacer. I had most difficulty creating coincident mates because the edges were all rounded, and often didn’t lend themselves well to that type of mating. Eventually, I would click on the correct two lines or faces or combinations of the two, and the parts would come together correctly. What did you learn from the project, how much time did you spend on it? Do you have any suggestions to make the project experience better?I was able to take away a lot from this project; I was able to learn more about free form drawing in terms of using the spline tool, I gained a lot of experience in using surfacing, and I was given my first opportunity to free design my own product. I value being able to design my own product because I could potentially include and speak about this project in an interview portfolio. Also, having to answer the questions in the write up that followed forced me to take design intent and purpose into consideration; I considered which materials I would use and why I would use them. I spent approximately 35 to 40 hours on this project.I really enjoyed completing this project, but the one thing I thing could be improved on is taking away some redundancy. For example, I felt as though the learning associated with completing a task for the “three most relevant parts” could have been accomplished with a single part.How did you find the course learning experience in general? What did you like the most? Any suggestions to improve/changeOverall, I enjoyed taking the course. I hadn’t taken a Solidworks course since my freshman year, and I liked that the course started from the most basic tools and worked all the way up to using all of the tools SolidWorks had to offer. For the most part, the tutorials were very comprehensive, and proved good examples that I could look back on if I was every struggling with a concept. I also really liked that I was able to become certified in Solidworks through this class. The only improvements that I would make would be to make revisions to the textbook where they are needed. There were some instances in the tutorials where there were mistakes that made completing the design extremely frustrating and nearly impossible. ................
