ENGGEN 115: Design Project 2, Sem 2, 2021 Design Project 2: CAD Design of Toy Play Set Version 2 -230 Aug 2021 14 % of course marks. Online submission through Canvas. Project dues dates: Checkpoint: 6:00 pm, Monday 30 August (week 6) Final Submission: 10:00 am, Friday 17 September (week 7) Hi designers, Welcome to your second design project for ENGGEN 115! In DP2 you will be creating 3D parts and assemblies (using Autodesk Inventor) of a toy play set compatible with a LEGO Figurine. The theme for the play set is “Olympics – the ball is in your court”, and this is a chance to let your imagination run wild. The project allows plenty of creative freedom and should be a lot of fun. However, it will be fairly time-consuming, so make sure to start early and manage your time well. An average student getting an average mark is expected to spend about 20 hours on this assignment. You may need more hours or less hours to complete it. First of all – at some stage you should read all of these instructions! Yes, they are long and detailed, but we want to ensure there is sufficient detail to convey your design task without ambiguity. Reading and understanding instructions is an important skill for an engineer. To start with, you could read Sections 1, 2 & 3 in full and skim over the rest to know where to find information later. The DP2 Intro and FAQ page will be updated on Canvas as the assignment progresses, so make sure to keep up to date with that, and use piazza for any further queries you have. Enjoy! – Stephen Version 2 updates: updated Checkpoint due date, fixed checkpoint submission elements, added workplane to advanced features. ENGGEN 115: Design Project 2, Sem 2, 2021 Contents 1.

Learning Outcomes At the end of this project, students should be able to: Apply and document the stages of an open-ended design process. Work on a design problem that includes both the creation of a new design, and working with existing components. Use CAD software to generate parts, assemblies, and drawings, as well as understand the benefits of using CAD in the creation and revision of designs. Plan and implement CAD strategies to create robust and editable CAD parts and assemblies. Communicate different aspects of the same design to different stakeholders. 2. Background and Problem Definition To ground this problem in reality, we the teaching team will be your hypothetical client. For the sake of this project we are the directors of a successful toy company, ENGENder JoyTM , that want to give back to society by creating a new range of toy play sets with the theme “Olympics – the ball is in your court”. You are a group of junior engineering design consultants who we have tasked with creating and communicating a new toy play set design, as per the provided problem statement below. It is then over to you to further frame the problem definition, including choosing the specific stakeholders and needs that your design will target. 2.1. Problem statement The much delayed and debated Tokyo Olympics have just closed and the Paralympics are about to begin, once again providing a demonstration of the competitive human spirit. According to the UN: “Sport has proven to be a cost-effective and flexible tool in promoting peace and development objectives” [1], and the Olympics provides a great opportunity to get children interested in sports. However, while most of the whole can enjoy watching, only a small fraction of children will ultimately be able to compete at that level. Further, a large proportion of the population have either limited access to, or are just not inclined towards, the competitive sports that are included in the Olympics. Considering these factors, there is an opportunity for a well-designed Olympics themed* toy playset to inspire children to be engaged in sports, or other games and competitions. It should be fun and interactive, and compatible with a LEGO plastic toy figurine. * The playset theme should represent a competitive Olympic event, but this is *not* limited to an existing event or sport: it could be any real or invented sport/game/competition that you choose. 2.4. Where to find inspiration The best source of inspiration is your own research and personal experience. What sports/games/ competitions do you like participating in What about when you were a child What would your dream sport be if you could invent one What about an underrated, boring or obscure sport you could promote with an exciting toy It’s completely up to you. Some examples are provided below to spark your imagination, but we want to see new and innovative designs, let your ideas run wild! ENGGEN 115: Design Project 2, Sem 2, 2021 Remember: You are not limited to replicating existing Olympic events or sports, think outside the box! While you will begin this project by making a LEGO block and assembling a LEGO figurine, your play set design should *not* be made of LEGO blocks. It only has to connect in some way to your LEGO figurine(s) (Section 4.3). Existing commercially manufactured play sets can be used for inspiration for your design, but yours must be unique and different enough to be sold next to the existing products. Figure 1. Some sport themed toy play sets for inspiration. Yours is not meant to *be* made of LEGO pieces, but should be compatible with a LEGO figurine. Sources: [2]. ENGGEN 115: Design Project 2, Sem 2, 2021 3. Project Instructions So, what do you need to do As an engineering design consultant, you will be completing all the required design work. Remember that this is an individual project. You are permitted to help each other with learning CAD and understanding the project requirements, but all design work and creation of CAD models must be your own. The table in Section 3.1 below describes the four main stages of the project, with a suggested sequence of tasks to complete, and the related assessment and submission details. While you do not need to stick to this sequence exactly (and you are encouraged to loop back and iterate as needed) we suggest you at least tick off each step to complete the project in full. 3.1 Suggested sequence I. Begin Stage A and Stage B in parallel II. After completing B, begin Stage C. It is encouraged to start this before the Checkpoint. III. Monday 30 August: Checkpoint (summary of submission below). IV. Begin Stage D once you have a final design near completion in CAD. Ideally 2 weeks before final submission. V. Friday 17 September: Final submission (summary of submission below).

Use the Submission checklist (Section 7) and submit to Canvas, then *check* that the submission was successful All ^All ENGGEN 115: Design Project 2, Sem 2, 2021 4. Design Requirements 4.1. Minimum design constraints To provide some consistency between submissions, and a minimum complexity of designs, the playset must comply with all of the minimum design constraints below. Requirements – Miminum design constraints Must be on the theme “Olympics – the ball is in your court”. As per the problem statement, you get to decide on the sport/game/competition that will be an Olympic event. The playset may be inspired by an existing commercial playset, but can’t be an exact copy. You’re welcome to measure and reverse engineer features of existing toys, as long as you do 100 % of the CAD yourself. Your final CAD assembly must include one or more LEGO figurine sub-assemblies, and in addition a minimum of: o six (6) parts that you have created. o three (3) of these parts need to be unique. o a sub-assembly containing at least two (2) parts is to be connected to the LEGO figurine (details in Section 4.3) o there is no upper limit for the total number of parts or sub-assemblies. However, a large number of parts does not necessarily correspond to a high mark. Connected parts of your playset should be intended to push/click/snap/glue together somehow (see Section 4.3). You are not allowed to acquire CAD files from any other source. You are welcome to follow online tutorials to create certain features, as long as you do 100 % of the CAD yourself. Opaque plastic parts should be made from ABS Plastic. Other materials can be specified for parts that cannot be made from ABS Plastic (for example steel for wheel axles, rubber for tyres, or another transparent plastic for windows). Your design must *not* include the LEGO name or logo on the design or poster (you are an independent consultant, not working for LEGO ). You are allowed to use any appearances/colours/decal that you want (apart from LEGO branding). The use of a suitable appearance will be weighed into the design quality mark. However, note that: o avoid black where possible, as this can make parts very difficult to see in shaded drawing views. You might want to choose a dark grey colour instead. o applying attractive decals should supplement a good CAD design, it can’t make up for an overly simple CAD implementation. 4.2. Design quality The marking rubric includes “Design Quality”. Quality is not that easy to define, but is a requirement that is very important when you compete for contract. An example to help you understand design quality will be posted on the FAQ page (Module D page 21). 4.3. Connections Part of the new playset (specifically part of a sub-assembly containing at least two parts) must be able to physically connect to the LEGO figurine. There are several different ways the figurine can connect to you’re a part of your design (see Figure 2): 1. Hold it in the hand (some aspect of the playset must snap into the hand). The part connecting to the hand needs to have an outer diameter that is the same as the inner ENGGEN 115: Design Project 2, Sem 2, 2021 diameter of the hand (drawing of the hand is found in the figurine tutorial). Note that the angle of the elbow is slightly different in the CAD file and the physical figurine. You need to design so it fits the CAD file. 2. Stand on it (must connect to the holes under the feet). You can use the same stud dimensions and spacing that you use for the LEGO block in stage A (also applies to sitting). 3. Sit on it (must connect to the holes on the back of the legs) 4. Connect to the head. 5. Fit around the neck. 6. Fit around the body in another way. 7. Connect to the figurine in a way that we didn’t think of. The way the playset connects should be obvious to a child. Figure 2: Examples of ways the figurine can connect with the playset. A note about tolerances: We will not worry about tolerances in this project. Although a real item must adhere to specific tolerances, you can make parts that connect together the exact same size. For example, a part that should be snapped into the hand should have an outer diameter of 3.00 mm. 5. Deliverable Requirements/Instructions 5.1 Workbook Workbooks or design journals are essential tools for capturing your ideas and process as you work on a design. Workbooks are often used in industry to document the work on a design. They may be physical paper books, or they may be digital documents. The workbooks fill important roles when it comes to – for example – design revisions, troubleshooting, and legal issues. Document your design process and progress in a single workbook. The workbook should be formatted as shown in class. Make sure you date your work as you go. Printed images, research, and calculations can be included your workbook, with references included where necessary (https://learningessentials.auckland.ac.nz/referencing/). Your workbook may be a physical paper book or a google doc. All workbooks are due at the specified deadlines, regardless of type. An example workbook pdf is available on the CANVAS page. The list below outlines the parts of the design process you are expected to record in your workbooks, expanded from DP. ENGGEN 115: Design Project 2, Sem 2, 2021 Requirements – Workbook content Problem Statement Stakeholders Research (design task, constraints) Initial PDS development Three concepts – ideas, sketches, inspirations, notes, etc. (up to here due at Checkpoint) Concept selection Updated PDS Layout sketches for CAD CAD implementation – notes on your plans, then what worked, what didn’t Detailed design – note any significant observations/changes to the design as you progress CAD strategies and Advanced CAD features – in the very last entries after your design is complete, compile your evidence of the CAD Strategies and Advanced CAD Features (see Sections 5.2 and 5.3). Workbook checks In class tutorial workbook checks may occur if time permits, but will not count towards DP2 grading. 5.2 CAD strategies Marks will be awarded for good use of CAD strategies. You will be guided to implement these in the LEGO block (Module D page 22), and then it will be over to you to implement a layout sketch, key dimensions and named features in one of the parts, and document this in your workbook. You are encouraged to use these strategies in reasonably complex parts, but will only be assessed on the one part you identify at the end of your workbook. For your selected part you should have: Layout sketch(es): start by sketching a preliminary layout sketch(es) in your workbook (as Stephen showed for the phone stand and LEGO block), and then implement this in CAD at the top of your model tree. Key dimensions: add at least two (2) named parameters to your model that control key dimensions of the part. Named features: name the features in your model tree to document design intent. Requirements – CAD Strategy Submission At the end of your workbook, create clear section headings for (replace the red text): o “CAD strategies for *Part Name*” Take clear screenshots (as you will be guided through in the LEGO block CAD strategies Checkpoint submission) and compile the following: o Hand sketched layout sketch o Layout sketch implemented in CAD o Parameters window, with two (2) parameters identified as your “Selected key dimensions” o Model tree showing feature naming and geometry of part 5.3 Advanced CAD features Marks will be awarded for proper use of CAD Features that are beyond the basic features you have learnt in the phone stand and LEGO block & Figurine tutorials. You will be awarded one (1) mark ENGGEN 115: Design Project 2, Sem 2, 2021 per feature up to a maximum of four (4). Note that some are much simpler to apply than others, and well within a beginner’s ability. Have a try of those in bold to start with. Advanced CAD features include, but are not limited to (in alphabetical order): 3D features/other: 3D sketch (not ‘2D sketch’), bend, coil, combine, derive, direct edit, draft, freeform, gear generator (bevel, spur or worm), grill, loft, rib, split, stress analysis (can be for a single part, doesn’t have to be the entire assembly), sweep, thicken/offset, work axis, work point and work plane (not ‘Offset from Plane’ option), zebra analysis tool. Sketch features: equation curve, extend curve, helical curve, slot, spline, split. Surface features: delete face, extend surface, patch, ruled surface, sculpt, stitch, replace face, thicken/offset. If you have used a feature that isn’t listed, please post your question on Piazza. If approved, it will be added to a list on the FAQ page (Module D page 21). The following features are not considered advanced: extrude, chamfer, fillet, hole, mirror, pattern – rectangular and circular, shell, revolve, ‘Offset from Plane’ workplane. Requirements – Advanced CAD Features At the end of your workbook, create a clear section heading for “Advanced CAD features”, and in this section: o clearly identify each advanced feature(s) you wish to be marked for. If you list more than four, only the first four will be marked. Identify the part file that the feature can be found in, and what the feature name is in your model tree. o explain the application of each advanced feature(s). Write one or two sentences about how you used the CAD feature to achieve the geometry you needed for your design. For example: “Extrude was used here to take a rectangular sketch and extrude it into a rectangular box. This box became the body of my Tablet part”. 5.4 3D part and assembly models After completing the LEGO Block and Figurine tutorials, you will be ready to start creating models for your toy playset design. By this stage you are expected to have the basic CAD skills required to continue on to building more complicated designs, however, if you’re struggling make sure to: – ask other students for help on Piazza, but please use generic examples that are not directly related to the project. For example, if you want to make a ladder for a swimming pool, you could ask “Any idea how I could make a curved ladder ” – aim to make early progress, so that challenges can be discovered and resolved early. – Use online tutorials to learn new CAD features. Finding good ones is a useful skill! – Make use of tutorial sessions in week 6 and 7, and the Part 1 assistance centre mentors. – Additional CAD guidance, including how to use some advanced features will be posted in the Part D module on Canvas. Requirements – CAD parts: All parts and assemblies should be made in a new project in Inventor. Must be created using Autodesk Inventor Professional 2021. Must use metric units, especially mm for length. Students caught sharing files for their project will face penalties. ENGGEN 115: Design Project 2, Sem 2, 2021 5.5 Technical drawings The purpose of the technical drawings is to communicate your design to the ENGENder JoyTM engineering department, such that it could be assessed for manufacture. You are required to make an assembly drawing and a detailed part drawing. Guidance on how to create these is provided in the tutorial for Stage A of the project, and will be discussed further in lectures in weeks 6 and 7. Requirements – Both drawings: Use the provided UOA drawing template, size A3, landscape. Instructions for how to download, install, and use the template is covered in Stage A. Fill out the relevant information in the title block. Follow the same steps as in Stage A. Requirements – Assembly drawing: One to three (1-3) drawing sheets showing the complete playset. Include all assemblies/sub-assemblies. Different sub-assemblies can be shown on different sheets. The figurine(s) should be connected in the intended way. The parts should be in positions that would be physically possible. Use coloured/shaded settings without hidden lines (Do not use the wireframe setting). Include at least one isometric view per sheet (can be exploded views, if desired). Additional views can be added to communicate aspects of the design. Include parts lists such that every part is accounted for. There should be at minimum a column for part number, no empty columns. Include balloons. The balloons do not need to point to the parts of the figurine (head, torso, arms, legs, hands, hips). If a part is hidden, you may not be able to add a balloon. You can choose to add view to show the part, or just skip the balloon for the hidden part. However, all visible parts should have balloons. Include additional views if needed to clearly communicate the design. Requirements – Detailed part drawing: One (1) drawing sheet to communicate the important geometry of one (1) of your parts. Use wireframe without hidden lines (Do not use the coloured/shaded setting). Include at least three (3) orthographic views. Include at least one (1) section view to show inside the part (this can also count towards the three orthographic views). Include at least six (6) relevant dimensions. Some parts will be too simple to have six dimensions, so please pick a part with enough features to achieve this. Do not include redundant dimensions. You do not need to fully specify the geometry of the part with dimensions. If you do not fully specify the geometry, you must include a note that says “For full geometry see CAD model “name_of_part”.ipt. Do include centremarks or centrelines where appropriate. Export your drawing as a PDF document. *IMPORTANT*: Follow the recommendations on how to layout views and add dimensions to drawings that are covered on pages 120 – 145 of the coursebook and will be covered in Week 6 and 7 lectures. You may of course prepare your drawing before the lectures, but it is advised that you check it again after the lectures. ENGGEN 115: Design Project 2, Sem 2, 2021 5.6 Poster The purpose of the poster is to communicate the design to a hypothetical user/buyer, and the ENGENder JoyTM marketing department. It should highlight the best features of your design. The poster can also be created to be the backside (and/or front side) of the playset retail cardboard box. Requirements – Poster On 1-2 pages (A4 or A3), explain the functionality of the playset. Include a 100-300 word section that sets the scenario for the playset. You can design this document as an actual poster suitable to be pinned to the wall, as a brochure, as the front and/or back of the retail box for the playset, or another document intended for the user/buyer of the playset. Include other texts and figures that explain how the playset works, if it can be used in different ways, if it is intended to be educational or interactive, or other information you think is important. You may use any software to generate the poster. You are expected to use a combination of text and images/drawings, but the format and style is free. You can use renders, or screenshots from Inventor, or even your drawings, to add images of your design to the poster. Include your name on the poster. Export your poster as a stand-alone PDF (don’t merge it with the drawings). 5.7 Photo-realistic rendering (optional) OPTIONAL submission: A photo-realistic rendering of your design. No marks are assigned for this part, but the best renderings will win a prize. You may want to use these tools to produce images for your poster, but this is not compulsory. No detailed instructions will be provided on how to create this. There are very powerful tools built-in to Inventor to create rendering which you can explore on your own. There are probably great tutorials available online. Search for them and see what you can find. Let your creativity loose! You can upload the rendering in any common file format, but please include the text “photo_rendering” (without quotation marks) in the file name so we can easily find the photo renderings. Do not put it inside the .zip folder. 6. Marking Marking will be according to the rubric posted on the assignment pages. 6.1 Late penalties Submissions will be accepted up to 48 hours after the deadline, but will incur late penalties as follows: Hours late Penalty > 0 to ≤ 2 hours 10% > 2 hours to ≤ 24 hours 20% > 24 hours to ≤ 48 hours 50% > 48 hours 100% ENGGEN 115: Design Project 2, Sem 2, 2021 7.

Learn more about LEGO If you want to learn how LEGO is made, check out: Inside LEGO : Robot Factory Where Toys Get Made If you are interested in the history of LEGO , check out: How LEGO Play Began LEGO continuously develops new products. This is from the 2017 annual report [3]: “New launches account for approximately 60% of the LEGO Group’s sales to consumers. More than 250 designers from more than 40 different countries make up the creative core of product development within the company, with the majority being based in the company’s headquarters in Billund, Denmark. The development activities that enable such an extensive degree of innovation comprise a wide range of initiatives from trend spotting and anthropological studies to the development of specific products and campaigns. The LEGO Group also cooperates with a number of educational institutions concerning various research projects within, among other topics, children’s play and new technologies.” Toy manufacturing is a billion-dollar industry, LEGO alone had a revenue of 8 billion NZ$ in 2017 [4]. To make long-lasting, well-functioning, affordable toys like LEGO takes almost rocket science. If you don’t think designing toys is the most exciting thing in life, you will use the same skills and knowledge you gain in this course to build airplanes and rocket ships. 9.
