ENR 118 SolidWorks Assignment 2017 Introduction This assignment is intended to provide students with the opportunity to put into practice and demonstrate what they have learnt in the course. This assignment is worth 50% of the overall course mark. Please read carefully the following requirements for your assignment. Assignment Requirements The assignment is based on the Engineers Without Borders Australia Challenge 2017 – East Santo Communities, Vanuatu. For background see here:- http://www.ewbchallenge.org/live-learn-vanuatu For this year’s assignment we will be working on Design Area 2 – Sanitation and Hygiene The EWB challenge has been modified for this course to be:- For the SolidWorks Assignment you are to model an assembled one person Ventilated Improved Pit Latrine (VIP) suitable for use in Vanuatu or other remote areas. The latrine is to feature a white 10 mm thick plastic moulded seat in the style of the Ballatrines tough toilet shown below with a folding seat and lid. The lid is to be fitted with a visible UniSA decal. http://www.bellatrines.co.nz/tuff_toilet.html The walls, door and roof are to be made of a suitable sheet material of your choice. The toilet is to include a 90mm PVC ventilation pipe painted black. Many designs for the VIP latrine can be found with a Google search to help with ideas. You only need to model the above ground components: Note: This course is not creating an entry in the EWB Challenge but is only using the topics as a basis for the Engineering Drawing with SolidWorks assignment. The modelled parts with part drawings provided should include (but you can do more modelling):- 1. Sub assembly of a Ballatrines tough toilet base, seat and lid 2. Piping and vent for the ventilation system 3. Sub assembly of a door frame made from a welded 25 x 25 x 1.6 mm RHS section 4. Door hinges 5. Sub assembly of wall frame made from a welded 25 x 25 x 1.6 mm RHS section 6. Door lock/handle 7. A full assembly made from a combination of all the parts 8. Adding a walling material (e.g. corrugated iron) is optional Dimensions for 25 x 25 x 1.6 RHS cross section (Can be found in toolbox as a standard part) SolidWorks Toolbox parts can be used for bolts, nuts and washers. The is to The drawings are to include - A tolerance size on the pin and holes for the hinged toilet and lid using a Loose Running H11/c11 fit. Use these limits of fit to specify the maximum and minimum sizes for the pin (shaft) and holes. - A flatness tolerance on the toilet seat lid - The sub-assembly drawings of the door and wall frame show 2 mm fillet welds all around the joints. - An appropriate surface finish on the plastic moulded toilet seat Each student must submit, using the ePortfolio template “ENR 118 Major Assignment”, the following via the learnonline ePortfolio submission link: - 1. A description of the items modelled, materials chosen and the modelling techniques used (150 to 250 words). 2. A zip folder of files including (items a to f, below):- a. All SolidWorks models (part, assembly and drawing files). All parts and assemblies are to be given a part number in the format of “Username xx” where xx is a 2 digit number series (e.g. 01, 02, 03 etc) b. Six detailed A3 sized part/sub assembly drawings for selected parts that show:- i. Dimensioning and linear tolerancing (all drawings) ii. Geometric tolerancing (on at least 1 drawing), e.g. circularity of pipe, flatness of toilet seat cover iii. Limits and fits (on at least 1 drawing) e.g. , pivot pin for toilet seat and lid iv. Surface finish (on at least 1 drawing) e.g. toilet seat Use 1 part per drawing sheet, each with a completed title block containing AS1100, 3rd angle projection, sheet size, part number and title. c. An assembly drawing of the total design with a bill of materials in the top RH corner and item numbers in balloons, detailed to AS1100. This drawing is to include a detail view and a section view. Dimensions should not be shown d. An exploded view drawing of the design with a bill of materials in top RH corner and item numbers in balloons to AS1100. e. All other files created for the assignment. 3. A display of all SolidWorks engineering drawings (they must be in jpg format) with a resolution that can be clearly read. 4. Two high resolution photo rendered jpg images (up to 5MB) of the design. One with a plain background and the other with the Vanuatu site provided (see course website for image jpg file). A visible UniSA logo (see course website for image) that is applied as a decal is to be included on the model. Vanuatu site scene to be used image background UniSA Logo (image modified from http://www.ewbchallenge.org/challenge/1773/node/1802) 5. An avi animation of the toilet seat and lid in operation and/or the assembly being exploded and assembled (up to 20 MB) for at least 10 seconds. 6. A self reflection on learning and achievements from the course (50 to 100 words). Due Date Students will be required to submit their work via learnonline ePortfolio submission link that will link and lock your completed ePortfolio to the assessment task. Due date: see course site. Special Note: For your work to be assessed you must include all your SolidWorks parts, assembly and drawing files. Your work will be checked for its author and date of creation. Submission of work created by others without due reference (excludes parts from SolidWorks Toolbox) will result in zero for that assessment task.
