Q3:Assignment 2 - Reverse-Engineering: Functional Analysis, Design for Manufacture, and Environmental Impacts In this assignment, you are asked to undertake the reverse-engineering of a consumer durable (or similar product) in order to consider its overall design and that of its individual components. Central to the activities you undertake will be the analysis of its design for manufacture, the construction of a function hierarchy (Functional Analysis), and lifecycle analysis. There is a selection of very cheap toasters, irons, and hand-mixers available, and the disassembly is done in groups of four or so, (in order to economize on the number of products destroyed!). However, if you are able to find some other defunct product to use in this exercise, you are welcome to use that, (subject to checking suitability with me). Additionally, if you provide your own product, you can select your own disassembly group size and members. Health and safety are paramount in doing this exercise. It is important that the product you use for this disassembly is disposed of after this exercise. If the product you plan to disassemble uses mains electricity, it is a condition of using it for this exercise that before commencement you cut to electrical lead as close to the product as possible to prevent subsequent use. In conducting the reverse-engineering exercise, you should review the operation and performance of the product and consider how each of the components contributes functionally to the operation of the product. Use this to construct a functional hierarchy./nYou should then select two components from the product and produce a brief report on each discussing the design choices they embody. You should also use the software, Open CL, (to which you will be introduced), to estimate the environmental impacts of your two components. Ensure that the components you choose represent different manufacturing processes, and thus different DFM and potentially different environmental impact issues. (For example, do not select two injection molded components; for maximum marks you need to show an understanding of a wide range of DfM considerations, and even if different components, two components of similar manufacture will tend to embody the same points.) If you are sharing a product, ensure that you chose different components to discuss than those of your colleagues. Probable reasons for the choice of material and choice of manufacturing process should be briefly explained, but far and away more important is that you should highlight features of the component which have been designed to aid manufacture or assembly, (or perhaps compromises in this regard to satisfy other product characteristics). Nota Bene: The DfM/LCA submission should solely focus on those aspects of the components. You should not include a discussion of how you disassembled the product; it is not of interest here. Moreover, whilst you are expected to identify the manufacturing processes used, and the reasons for their selection, you may assume that the reader is familiar with the processes. Generic explanations of the processes are NOT required, and will not gain any marks.See Answer
Q4:Part 2: Designing Lift Arm Assembly In Part 2 of this OEMP project you will be designing two aspects of the Lift Arm Assembly while ensuring functionality of your design. You will be selecting the length of parallel members CD and EB, as well as the height of chair assembly DEF. Throughout this project, all team's will be using US Customary units (pounds, slugs, feet, inches). E LOF do H d hu hg hc Figure 1: Side View (x-y plane) of Pool Lift with variable dimensions The lift arm assembly consists of a four-bar linkage, BCDE, where members CD and BE are the same length and remain parallel to one another at all times. The four-bar linkage ensures that the seat mount/chair DEF will maintain a vertical orientation throughout its motion. The goal of this OMEP is to develop your team's most competent Pool Lift Model allowing for a variety of users to comfortably enter and exit the pool safely. To limit the scope of this project, all teams will use the following dimensions: hc=56 inches and do = d = 2 inches, where he represents the height of pin C above the pool deck, hg represents the height of pin B above the pool deck, and de and d represent the length of hinges G and H, respectively, from the pin to the centerline of the member to which each hinge is attached. The lift arm assembly must be designed to successfully achieve your chair's selected vertical range of motion while limiting the necessary operating range of a angles (suggested less than 60°). Consider how the length of the parallel members and the height of the chair assembly affect the chair's vertical position. • Design the length of parallel members CD and BE (lcp in figure 1). Design the height of chair assembly DEF (DF in figure 1). Select the height of pin B above the pool deck (hg in figure 1). Based on your design, use geometry to find the a angles corresponding to your maximum and minimum chair positions. If your range of operating a angles is greater than 60° you need to consider redesigning lcD and lor as large ranges of angles may cause the hydraulic cylinder to overextend.See Answer

Q12:Q2) When storing chocolates, care must be taken to avoid the fat bloom at high temperature and sugar bloom on the surface of the chocolate at low temperature. It is best to store chocolate at constant temperature. However for practical reasons to the present exercise, let's say it is required to avoid the temperature below 10 °C and should not exceed 20 °C. Use the utility plot and graph the usefulness of the gain in performance by stetting the S- curve as measure for the performance for the chocolate bar over the given temperature range. Define the values of the plot and the variable at the abscissa.See Answer
Q13:Q3) The auxiliary power unit for trucks (APU) provides air conditioning during driving breaks while eliminating the need to idle the engine. This technology could help eliminate large quantity of carbon dioxide emissions from truck idling. Designing such APU requires considering the house of quality of such design. The APU has a maximum weight of 75 kg with a turbine weight of 3kg and 2.5 kW shaft power. It operates at control inlet temperature of 1000°C. The target of bleeding air will be specified at later stage. Consider using a house of quality (HoQ) to explore the Auxiliary Power Unit for trucks (APU). A manufacturer wants to explore the possibility of designing an APU that satisfy the drivers (Who). The information and the table below are prepared by the designer for HoQ elements (Hows, Whats, Who, Now and Target (How much)). Do the followings; Use the information given in the table below to construct the complete HoQ (make sure the What's, the Who's, the How's, the Now's and Targets are shown in the HoQ) Use the given ranking values and the Symbols to a) Use the information given below to construct the complete HoQ b) Do tradeoff between How's Versus How's c) Rank the evaluation of the Who (Drivers) versus What's d) Rank the evaluation of the How's versus What's e) Calculate the importance rating of the How'sSee Answer
Q14:-- PIFCO INSTRUCTION MANUAL/n ENG3017 Mechanical Design 3 2023-24 Assignment 2 - Reverse-Engineering: Functional Analysis, Design for Manufacture, and Environmental Impacts (20% of total module assessment) In this assignment you are asked to undertake the reverse-engineering of a consumer durable (or similar product) in order to consider its overall design and that of its individual components. Central to the activities you undertake will be the analysis of its design for manufacture and assembly, the construction of a function hierarchy (Functional Analysis), and a lifecycle analysis. There is a selection of very cheap toasters, irons and hand-mixers available, and the disassembly is done in groups of four or so, (in order to economise on the number of products destroyed!). However, if you are able to find some other defunct product to use in this exercise, you are welcome to use that, (subject to checking suitability with me). Additionally, if you provide your own product, you can select your own disassembly group size and members. As you conduct the reverse-engineering exercise, you should review the operation of the product, and thus consider how each of the components contribute functionally to the operation of the product. Use this to construct a functional hierarchy. Construction of the functional hierarchy will be conducted as group exercise in class, in the tutorial sessions of 25th Jan, and 1st Feb. There is no formal assessment of this, but if absent, you may be required to submit a single page function hierarchy for your product, (not a report), to demonstrate you have engaged with this content. (Failure to engage may result in a reduction of one grade point on this assignment.) Health and safety is paramount in doing this exercise. It is important that the product you use for this disassembly is disposed of after this exercise. If the product you plan to disassemble uses mains electricity, it is a condition of using it for this exercise that, before commencement of the disassembly, you cut the electrical lead as close to the product as possible to prevent subsequent use. For the individual assessment, you should then select two components from the product and produce a brief report on each, discussing the design choices they embody. You should also use the software, OpenLCA, (to which you will be introduced), to estimate the environmental impacts of your two components. Ensure that the components you choose represent different manufacturing processes, and thus different DfM issues, and potentially different environmental impact issues. (For example, do not select two injection moulded components; for maximum marks you need to show an understanding of a wide range of DfM considerations, and even if of very different in function, two components of similar manufacture will tend to embody the same points.) If you are sharing a product, ensure that you chose different components to discuss than those of your colleagues. Probable reasons for the choice of material and choice of manufacturing process should be briefly explained, but far and away more important is that you should highlight features of the component which have been designed to aid manufacture or assembly, (or perhaps compromises in this regard to satisfy other product characteristics). Nota Bene: The DfM/LCA submission should solely focus on those aspects of the components. You should not include a discussion of how you disassembled the product; it is not of interest here. Moreover, whilst you are expected to identify the manufacturing processes used, and the reasons for their selection, you may assume that the reader is familiar with the processes. Generic explanations of the processes are NOT required, and will not gain any marks. Deliverables Design for Manufacture (Individual Submission) - 20% of total course assessment A report on two components. In effect this should be in the form of two mini-reports. (i.e., There is no requirement for a general introduction or overall conclusion.) Word count For guidance, 800 - 1200 words should be sufficient (2 components x 400 - 600 words per component/sub-assembly). You should not worry if you are slightly over or slightly short of this target, but long-rambling irrelevance and omission of relevant points are sins of equal measure.

Q20: MAIN INSTRUCTIONS Assignment: New or Evolved Product Manufacture and Launch - 3000 words. The assignment requires you to plan the production and introduction of a new product using a concurrent engineering approach. You should consider your product to be new to the market or at least a new variant of an existing product. You must first decide on a product, it may be a: mobile phone, computer, electric drill, food mixer, electric kettle, pen, watch or anything you choose. Whichever product you select, it should have at least 10 component parts so that you are able to plan its production and describe the process planning requirements. If you select a complex product like an automobile, you can restrict your process planning to one of its sub-assemblies. Also describe the design of the product development. You are expected to cost out the project from the initial concept stage to delivery of the product. This includes the design of the product, design and creation of the manufacturing facilities; the cost of manufacturing operations; sales and delivery. You must explain whether you will manufacture in your own factory or sub-contract the manufacture, how and where the product will be assembled? Whatever you decide to do, I still require the process planning and method of manufacture to be described. Also if you subcontract the manufacture I want to know how you will protect your product so that it cannot be stolen by the sub-contractors. You need to imagine that you have decided to invest your own money into this project and this will motivate you to make the new product introduction and launch a success. An important decision is to decide the price that the product will sell for and also the anticipated volume of annual sales. You also need to decide on your profit margin in order to evaluate your budget. You should make sketches of your product, it would be good to do this using our CAD facilities but it is also acceptable to provide hand drawn sketches I expect to see the following sections in the essay, the percentages indicate the proportion of the mark that can be obtained for each section 1. Drawings of the product & component parts 5% 2. A section on the design, prototyping and test strategy, the materials used should be specified and justified for each component part. 10% 3.
