Chapter 2 LITERATURE RIVIEW

2.1 Definiton of engineering design processTheengineering design processis a methodical series of steps that engineers use in creating functional products and processes. The steps tend to get articulated, subdivided, and/or illustrated in a variety of different ways, but regardless, they generally reflect certain core principles regarding the underlying concepts and their respective sequence and interrelationship. Also, the process is highly iterative - i.e. parts of the process often need to be repeated many times before production of a product can begin - though the part(s) that get iterated and the number of such cycles in any given project can be highly variable.

2.2 Definition of President Universitys chairPresident University's chair is a collage chair that use for all learning and meeting process in President University. Designed specifically only in President University and will not be found in any other university. A chair with a table for study as well as in the collage chair in general, but with different strengths and uniqueness that distinguishes it from other similar products.

CHAPTER 3 DISCUSSION3.1 Adventages and weakness as well as how to improve the weakness3.1.1 Adventages1. Sponge as a seatside and backside is very comfortable 2. Distance users foot to the ground is is make the user's feet comfortable 3. Tabble design is flexible, removable table. So the chair can be used as learning chair or formal event chair (when the user drop the table) 4. The table can be rotated by a certain angle, making it easier for the user in the learning process 5. The distance between the table and the user's body is quite convenient for people who have a large body3.1.2 weakness1. sometime its part separated from its chair (between table and chair itself)2. feeling a shake. Either vertically or horizontally wobble. Shaking in the vertical happens Because The table is flexible, you can rotate it with the angle that you like. Several but after time, that part feeling a shake. Not strong anymore. And shaking in the horizontal happens Because The pipe from the connected table and chair sometime separated. As We've said in the first point.3.1.3 improvement1. make the pipe longer, then we will use the bolt on the inside of the seat, more precisely on the back of the pipe. So the table will still be removed. However, to remove the need for tools. It is aimed that the table will never be separated again by accident. It also would eliminate the wobble horizontally. 2. after that we will make a flat section of pipe under the table becomes wider area. It aims to reduce the sway forward and backward (vertical) after a long time its chair used.

3.2 Materials and machines that we use to make a President Universitys chair3.2.1 Materials1. Sponge,2. Iron pipe,3. Iron plat,4. Bolts & skrew,5. Ruber,6. Glue,7. Multiplex,8. Wood,9. Vernish,10. Paint,11. Vinyl,3.2.2 Machines1. Bending MachineIts purpose is to assemble a bend on a workpiece. A bends is manufactured by using a bending tool during a linear or rotating move. The detailed classification can be done with the help of the kinematics2. Welding MachineIs a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material3. Deep Drawing MachineIs a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch4. Milling MachineMilling is the process of using rotary cutters to remove material from a workpiece advancing (or feeding) in a direction at an angle with the axis of the tool5. Cutting MachineIs any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools.

3.3 Steps to make a President Universitys chair1. Make the frame from the chair, first we make the kick frame with the iron pipe, using the cuting machine to cut the iron pipe then use bending machine to bend the pipe become U-form. And make the suport kick frame with the iron plate material using cuting machine to cut the plate become thats form, then we joining with welding process,then we painting this part, like the picture. (1)Then the second, we make the connector around the kick frame from the same iron pipe with kick frame. Using cuting machine to cut this iron pipe and we make the support part with the iron plate material and use cuting machine to make this plate become that form, then use drilling machine to make holes for the bolts. Then joining those parts with welding process. Then we painting this part. (2)Then the third, we make the kick stand from the iron pipe with diameter 0.5 cm and using cuting machine to cut this iron. And use the iron pipe with diameter 0.3 cm to make the place for book with bending process. Then after that we joining those part with welding process. Then we painting tis part. (3)Then the fourth, we make the suport part for the backside and seatside. We using iron pipe and using cuting process to cut this pipe and use bending machine to bend the pipe become L-form. And make the house skrew for suport the backside chair from iron plate material and use cuting machine to make that form and use drilling machine to make the holes for the skrew. Then we joining those parts with welding process, then we painting this part, like the picture. (4)Then the fifth, we joining the the all parts from the frame. We joining the kick frame with the kick stand (3) and the connector of kickframe (2). We use welding process to jaoining the kick frame with the connector kick frame and for the kick stand we just put the kick stand to the kick frame hole.(5)Then we joining the the kick frame sheet (5) with the support backside chair (4) with welding process. (6)2. Make the tabble sheet, first we make the suport leg for tabble, we use the iron pipe with diameter 2 cm and using the cuting process then we bend this pipe with bending mchine to make that form. Then we make the more side from tabble suport with the iron pipe with diameter 1.5 cm also use cuting machine and bending machine. And make the suport plate with iron plate, using cating machine an bending machine to make that form and we make the connector parts with iron pipe with diameter 1 cm. Then we joining those parts with welding process. Then we painting this part.(7)Then the second, we make the different side support tabble from the iron plate and using cuting machine to make the plate become smaller then use punch machine to make the plate have a hole. Then we make the engsel from the tabble with iron plate also and using punch machine to make the hole and make that form. And we joining those parts with the poros, then we painting this part, like the picture. (8)The third, we make the tabble. Using the multiplex material, then we use the cuting machine with jigsaw for make the form like on the picture. Then we use sand paper to make the sureface become clean and put the vinyl on the top surface then we vernish this tabble. (9)Then the fourth, we joining those tabble parts, we joining the the support part (8) with the tabble (9), we use skrew for joining this.(10)Then we joining the support tabble (7) with the tabble sheet (10) , we use welding machine to joining this. Like on the picture. (11)3. We make the backside and the seatside of the chair, first we make the seaside of the chair. We use wood and cut the wood become the form and put the sponge on top the wood with glue and we covering with syntetic leather then use a ruber to block the edge side from the seatside with strapless.(12)Then we make the backside from the chair, using same materials with the seatside. Use a wood and cut become the form and put the sponge with glue and covering with syntetic leather, and use ruber also to block the edge side of the backside with the strapless.(13)4. Joining all parts. First we joining the frame chair (6) with the backside (13) and seatside (12) chair. On this job we use skrew and bolts to joining those parts.(14)Then we joining the chair (14) with the tabble sheet (11), just put the connector from the tabble sheet to the holes from the support kickframe. And use a rubuer in the hole of the support kickframe for dicrease the struggle. After finish, take a bolt as the last steps (our improvement) (15)
