Activity 6.4 Structural Analysis Automoblox



Activity 6.4 Structural Analysis AutomobloxIntroductionYou have already performed a Visual Analysis and a Functional Analysis of your Automoblox vehicle. During this activity you will investigate vital product characteristics with regard to the structure of the product. You will research and document your findings using careful measurements, sketches, and notes which will complete the reverse engineering of your product. You will use the information you have gathered during the process in the next unit when you design an enhancement or accessory for the Automoblox vehicle.EquipmentEngineering notebookPencilAutomoblox vehicleGraph and isometric grid paperProduct Disassembly ChartMaterials Usages ChartProcedureIdentify each part of the Automoblox vehicle by name, quantity, size, function, material, finish, interaction of parts, and general notes using the Product Disassembly Chart to record your work.Create pictorial sketches, as necessary, to communicate the internal operation of the product. Staple the sketches to this packet!If you have not already done so, carefully measure each part using appropriate measuring devices.If you have not already done so, create annotated sketches of each part including an isometric pictorial (at least) and orthographic projections (as necessary) to detail the part with dimensions, material, and other characteristics. You may simply need to add annotations to sketches that you have previously created.Consider the choice of materials for the toy. For each part listed below, research the material used. Then either justify the choice of material or present an alternate material that you believe would be more appropriate for the part. Include mass, workability (in manufacturing), durability, strength, transparency, frictional properties, flexibility, and resistance to fatigue (failure due to repetitive use) in entries.PartMaterialJustification or AlternateWindshieldPolycarbonateTireRubberBodyHardwoodConnectorABSAxleProprietary polycarbonate blend (which includes a lubricant)Complete 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.Activity 6.4 Product Disassembly ChartProduct Name:Group members:Date:Time:Part#Part NameQtyDimensionsFunctionMaterialDensityMassor WeightTexture and FinishInteraction with Other PartsGeneral Notes(i.e.; wear, stress indicators)Part#Part NameQtyDimensionsFunctionMaterialDensityMassor WeightTexture and FinishInteraction with Other PartsGeneral Notes(i.e.; wear, stress indicators)ConclusionDescribe the process of Reverse Engineering.Part of the mission of Automoblox is to “offer a high quality building system that will delight and inspire children while fostering the development of important skills and learning foundations.” If given the opportunity, how would you improve the Automoblox design (visually, functionally, or structurally) while furthering the mission of the company at minimal cost?Activity 6.4 Product Disassembly Material Usage ChartFerrous MetalsCast IronHeavy equipment, machine frames.Carbon Steel 1000,4000,5000 seriesFasteners like rivets, nails, wire, chains and machine parts.
