ABSTRACTThe study of manufacturing was very important in order to carry out this projectto ensure that the student understand on what are needed to do. This project is aboutdesigning and fabricate “Multipurpose Portable Desk” to help people easy to bringanywhere. This project involves the process of designing the table by using consideringsome of factor such as shape and ergonomic for people to use. After the design iscomplete, it was transformed to real product where the design is used as a guideline.This project also required to ensure the safety for indeed of publishing. Methods andprocess involve in this project for instance joining using welding, rivet, shearing,bending and drilling. This project is mainly about generating a new concept ofmultipurpose and portable desk that would make easy to bring anywhere and morefunction. After all process had been done, this desk may help us to understand thefabrication and designing process that involved in this project.

ABSTRAKPembelajaran mengenai pembuatan adalah penting untuk menjalankan projek inibagi memastikan pelajar memahami tentang perkara yang perlu dilakukan. Projek iniadalah mengenai merekabentuk dan membuat meja serbegunabagi memberikemudahan kepada pengguna untuk membawa kemana-mana sahaja.

CHAPTER 1INTRODUCTION1.1: Project TitleMy project title is design and fabricate multi-purpose portable desk. Thefabrication of the table is concern to strength, durability, and more function. Newconcepts require improving portable multipurpose function such as easy to use.1.2: Project synopsisThis project is design and fabricates a Multipurpose Portable Desk. Theproject involved the design and fabrication. This desk can be adjusts to differentheights and angles and folds away too. Multi-purpose Portable Desk instantlyturns a chair or sofa into an eating, entertainment or work center. The desk mustbe sturdy and portable so it can use for flat for eating, writing, and doingpaperwork.Skill requirement during making this project is AutoCAD, mechanicaldesign, welding and basic machining such as shearing machine, bending machineand drill machine.

1.3: Project BackgroundAt this moment desk in market have various type, specification, andshape. Table used as place to put anything on them. Beside that table can used tostudy and making many works such as writing note, make assignment, and cando the drawing.As we know, desk is large, difficult to move and sometime not usingfriendly. In order to solve this problem, the desk that I design is considering allof current weakness. This desk design is more compact, user friendly due to wecan adjust the height and angle, portable and multipurpose.1.4: Project ObjectiveProject objective divide by two. It is general objective and specificobjective for the title of project.1.4.1: General ObjectiveThe objective of diploma final year project is to practice the knowledgeand skill in problem solving using academic research, in order to become a goodengineer that have been enough knowledge and skill.This project also important to train and increase student capability inresearch, analysis and problem solving. These projects also educate the student incommunication like in presentation and educate them to define their research inpresentation.

This also can produce and train student to capable of doing work withminimal supervisory and more independent in searching, detailing and expandingthe knowledge and experiences.The other objective is generating student that have capability to make agood research report thesis form or technical writing.1.4.2: Specific Project ObjectiveThe main objective of this project is:i.To design and fabricate a multipurpose portable desk.ii.Fabricate desk can be adjust to different height, angle and can fold.iii.To design a desk that is suitable to it application.iv.Introduce and fabricate new concept of desk.v.Fabricate the desk with minimize the manufacturing cost.1.5: Problem StatementsBasically this project is base on these problem statements: Existing desk in the market only has limited function. Many desks right now fit for their height and angle. Difficult to change the place because the desk not portable or can’t befold.

1.6: Project Scope Literature review- Consideration on the multipurpose and portable of the desk. Design product- Sketching and CAD drawing- Mechanical design application Fabrication product- Process involving basic machining and joining. Test and evaluation- Aspect to consideration:Strength, safety, ergonomic- No error from fabrication

CHAPTER 2LITERATURE REVIEW2.1: IntroductionTable used as place to put anything on it. Beside that table can be used towriting, study and making many work such as doing drawing, making homework andothers. We already know many table have a big size and difficult to move at other placeand bring it. So many designs right now become fordable table that have more easy touse, can fold, move to other place and bring it. Foldable table is thing that can fold fromlarge to become a small size such as briefcase, box and others. Fordable table is the mostinteresting to people used to camping, picnic because easy to bring it. Many products atthe market have different specification, shape and type when manufacture by differentmanufacturing company. Research review about fordable table is to get data to make anew concept of foldable table.2.2: Review Current Product
