Activity 6.4a Product Disassembly ALTERNATE



Activity 6.4a Product Disassembly ALTERNATEIntroductionHave you ever wondered how a product functions or what causes it to fail? Why can some products withstand extreme conditions and others cannot? Understanding how a product is made is not easy to determine by simply looking at a product. A technique used by many engineers is to disassemble a product to learn more about how it works and what makes it not work in some situations. Disassembly is a major step in the reverse engineering process. During this activity you will disassemble your product to investigate vital product characteristics and test your hypothesis as to the operation of the product. You will also investigate the structural composition of the product. During the disassembly process, you will research and document your findings using careful measurements, sketches, and notes. The information you record will help you in the next activity which will include 3D modeling, analysis, and redesign of your chosen product.EquipmentEngineering notebookPencilConsumer productStorage container for partsHand tools necessary to disassemble productGraph and isometric grid paperProduct Disassembly ChartMaterials Usages ChartProcedureCarefully disassemble your product and identify each part by name, quantity, size, function, material, finish, interaction of parts, and general notes using the Product Disassembly Chart to record your work.Create annotated sketches of each part including an isometric pictorial and/or orthographic projections (as necessary) to detail the part with dimensions, material, and other characteristics.Carefully measure each part using appropriate measuring devices and place your measurements on your sketches from step plete the Product Disassembly Chart to detail important aspects of each part.Sample Annotated Sketch of Part DocumentationThe following is an example of a part documentation using an isometric sketch with annotated notes of fillet, hole location, materials, finish part location, and interactive parts.ConclusionDescribe the process of reverse engineering.How did the process of disassembling the product aid you in understanding how the product works?What is the intended consumer use for this product?What parts would you redesign? Why? ................
